the present art overcomes the prior art limitations by providing a vehicle mounted feed hopper device . a prior art tmr holds between 140 to 1600 cubic foot of material and the present invention 1 will hold 10 to 100 cubic foot of material as shown in fig1 , within the class of mobile feed hoppers in the 10 to 100 cubic foot range . the present invention has a generally rectangular base 2 formed of angle iron defining a plane with two longitudinal side members 2 a and two lateral end members 2 b . the longitudinal side members are mutually parallel and spaced apart and the lateral end members are mutually parallel and spaced apart and perpendicular to the side members . at the intersection of an end member with a side member , the base has a leg 3 extending perpendicular to the end member , the side member , and the plane of the base . the base has an orientation to fit the invention transverse upon a transport vehicle , such as a light duty flat bed truck , thus the lateral end parallels the length of the truck . upon the base , the invention present invention has a metal enclosure 4 with a top panel 5 and a v shaped bottom 6 spaced apart and beneath the top panel . the top panel has a generally rectangular , planar shape , exceeding the dimensions of the base . within the top panel , an aperture ( not shown ) receives material placed within the invention from an external source . the aperture has a lid 7 upon it as shown in fig1 . the lid is also generally rectangular with a size exceeding the aperture but much less than the dimensions of the top panel . the lid includes a handle upon it for manual opening . opening of the lid occurs upon sliding it along a track , here shown as two mutually parallel and spaced apart rails 8 that extend outwardly from the aperture partially along the length of the top panel . similar to the base , the top panel has two longitudinal edges and two lateral edges . the longitudinal edges are mutually parallel and spaced apart and the lateral edges are mutually parallel and spaced apart and perpendicular to the longitudinal edges . upon one lateral edge proximate the rails 8 , as at 5 a , a back panel 9 depends perpendicular to and beneath the top panel 5 . the back panel is generally planar but of a pentagonal shape that comports with the v shaped bottom 6 . extending from the back panel , the present invention has two spaced apart bearings 10 and an outlet 11 proximate the vertex the v shaped bottom 6 . the outlet is generally round and hollow . the applicant also foresees the lid 7 having a width nearly that of the hopper itself , while still sliding upon rails . in an alternate embodiment , the hopper has the lid removed so that it remains open entirely during its usage . the hopper without a lid may have a hollow frame resting upon the hopper that stiffens the side panels , back panel , and front panel as it provides a warning to persons approaching the hopper . opposite the back panel 9 and depending from the top panel 5 upon the other lateral edge 5 b , a drive cover 12 extends beneath the top panel 5 and outwardly from the remainder of the enclosure . the drive cover extends generally opposite the chute as shown . the drive cover extends across the width of the top panel and descends to follow the v shaped bottom 6 . appurtenant to the drive cover , a motor cover 13 extends beneath the drive cover and along a portion of one half of the v shaped bottom . the motor cover conceals and shelters a hydraulic motor 14 secured to one leg , as at 3 a . spanning between the back panel 9 , the drive cover 12 , and the top panel 5 , the enclosure 4 has a side panel shown , here the left side panel 15 . the left side panel depends from one longitudinal edge 5 c of the top panel for the length of the top panel and generally more than the length of the longitudinal side members 2 a . the left side panel depends for a height that accommodates the desired volume , or capacity of the invention , generally the height exceeds that of the legs 3 . the height of the left side panel accommodates the internal mechanism for material handling , here shown as its bearings 10 in the back panel 9 . turning the invention towards the back panel 9 , fig2 shows an end view typically seen during unloading of material . the enclosure 4 of the invention 1 has its lid 7 centered upon the top panel 5 . from a lateral edge 5 a , the back panel 9 depends perpendicular and beneath the top panel . the back panel has a pentagonal shape with one edge parallel to the lateral edge 5 a , two mutually parallel and spaced apart side edges that join to the left side panel 15 and its counterpart right side panel as later shown in fig6 , and two other edges that attain a partially flattened v shape , as shown in this figure . the edges of the v shape have a rounded junction , centered upon the back panel and at the lowest portion of the back panel . upon the back panel between the side edges , the bearings 10 of the internal mechanism extend . the bearings have a position generally in line with the rails 8 of the top panel 5 . proximate the junction of the edges of the v shape , the back panel has its outlet 11 that discharges the material from the hopper of the invention . the chute has its hollow round shape as before . within the chute though , it has an outlet bearing 16 that supports a journal end of an internal mechanism later shown . the outlet bearing has a generally v shaped form with two attachments to the outlet generally towards the bearings 10 . inward from the back panel , the bottom 6 joined to the two edges of the v shape of the back panel accepts the legs 3 of the base 2 , here shown as two legs . in the background , one leg , as at 3 a in fig1 , receives the hydraulic motor 14 proximate the motor cover , that is opposite from the back panel . the legs 3 connect to the base at the lateral member 2 b and have a height so that the outlet is slightly above the lateral member . rotating the invention once more , fig3 shows a side view of the invention 1 generally along its length . the invention has its enclosure 4 connecting to the base 2 upon legs 3 as previously described . the enclosure 4 has its top panel 5 , here shown on its longitudinal edge 5 c , with the back panel 9 towards the right of the figure and mutually spaced apart from the drive cover 12 towards the left of the figure . the back panel has the bearings 10 of the internal mechanism extending outwardly from it and the outlet 11 also extending outwardly from the back panel and slightly above the lateral member 2 b of the base 2 . the drive cover 12 extends outwardly from the enclosure , that is , beyond the length of the top panel and extends downwardly , that is , towards the plane of the base 2 . beneath the drive cover , the enclosure has the motor cover 13 of shorter height and width than the drive cover , as later shown in fig4 . the motor cover shelters and conceals the motor 14 as previously described . between the motor cover , the legs , and the back panel , the enclosure has the left side panel 15 and a portion of the v shaped bottom , here at 6 a . the left side panel has a generally elongated rectangular shape of similar length to the top panel , particularly the longitudinal edge 5 c . the portion of the v shaped bottom also has a generally elongated rectangular shape of similar length as the left side panel but at an inwardly sloping angle from the left side panel . the inwardly sloping angle defines on half of the v shaped bottom . having mentioned the drive cover previously , fig4 shows an end view of the invention with the drive cover 12 in the foreground . the drive cover also has a pentagonal shape similar to that of the back panel . however , the drive cover has its pentagonal shape truncated proximate the intersection of the edges of the v shape by the motor cover 13 . the motor cover has a generally rectangular shape fitted upon the intersection of the edges of the v shape defining the bottom of the drive cover and with one corner of the motor cover itself truncated to follow the v shape of the bottom as shown . the motor cover rests upon a lateral member 2 b of the base and in front of leg 3 a , not shown , that supports the motor . above the drive cover , the enclosure has the top panel 5 with its lid 7 as previously described . after viewing the invention from two ends and a side , fig5 shows the invention from above . the invention 1 has its enclosure 4 with the top panel 5 that has a lid 7 upon rails 8 towards one end . proximate that end , the invention has the back panel 9 , here to the right , with the two spaced apart bearings 10 centered about and above the outlet 11 . opposite the back panel , the enclosure has the drive cover 12 connecting to the top panel and the motor cover 13 slightly beneath the drive cover . upon removing the top panel 5 , the drive cover 12 , and the motor cover 13 , fig6 shows the invention with its enclosure 4 and internal mechanism within the enclosure and the back panel 9 in the foreground . the enclosure rests upon the legs 3 of the base 2 as described above . the enclosure also has its back panel 9 , left side panel 15 , and bottom portion 6 a as previously described . the enclosure also has its right side panel 16 of similar dimensions to the left side panel and mutually parallel and spaced apart from the left side panel . spanning between the left side panel and the right side panel opposite the back panel 9 , the enclosure has its front panel 17 . the front panel has a similar pentagonal shape as the back panel . from the bearings 10 inwardly , the invention has a left mixer 17 having a plurality of paddles thereon , generally to the left of the chute 11 and extending to the front panel 17 , and a right mixer 18 having a plurality of paddles at a different orientation that the paddles of the left mixer , generally to the right of the chute 11 and extending to the front panel 17 . the left mixer and the right mixer are generally shafts with t shaped paddles extending perpendicular to the shafts . the left mixer and the right mixer counter rotate to assist in moving material or feed through the hopper . similar to fig6 , fig7 here shows the invention with its enclosure 4 and internal mechanism inside it but the front panel 17 in the foreground . the enclosure rests upon the legs 3 of the base 2 as described above . the enclosure also has its back panel 9 , left side panel 15 , and bottom portion 6 a as previously described . the enclosure also has its right side panel 16 of similar dimensions to the left side panel and mutually parallel and spaced apart from the left side panel . spanning between the left side panel and the right side panel opposite the back panel 9 , the enclosure has its front panel 17 . the front panel has a similar pentagonal shape as the back panel . from the bearings inwardly as previously shown , the invention has the left mixer 18 with fewer paddles shown in this figure and extending to the front panel 18 , and the right mixer 19 having a plurality of paddles , generally to the right of the chute 11 and extending to the front panel 17 . the shafts of the left mixer and the right mixer each connect to a sprocket , as at 20 , 21 respectively outwardly of the front panel . the sprockets rotate by action of a chain 22 , or other flexible elongated member , such as a belt , so that the sprockets rotate in opposite directions . the chain also turns a gear 23 connected to a screw conveyor , not shown . the screw gear also operatively receives a drive chain 24 , or other flexible elongated member , and the drive chain operatively connects to the drive sprocket 25 of the motor 14 . the hydraulic motor provides at least four horsepower suitable for simultaneously driving two mixers and the screw conveyor with material thereon . the hydraulic motor operates from the host vehicle hydraulic system . alternatively , the motor operates upon reduction gearing and shafts from the drive train of the host vehicle . from testing , the applicant has identified that electrical motors in this application would draw current in excess of the capacity of the typical host vehicle , or truck . alternatively , a gearbox drive , not shown , supplies direct mechanical power transfer from the host vehicle drive train to the conveyor and the paddles . the direct power transfer occurs through a gear box and related shaft or alternatively through load cells . upwardly from the two sprockets , the front panel also has a shelf 17 a that extends across the width of the panel and slightly outwardly from the panel , such as for the width of the chain . fig8 shows the driving mechanism of the invention more closely . as above , the left mixer connects to its sprocket 20 and the right mixer to its sprocket 21 outwardly of the front panel . the two sprockets have the largest diameter and largest tooth count of the components in the driving mechanism . the sprockets rotate by the action of the chain 22 , belt , or other flexible elongated member , in opposite directions . the opposite rotation occurs as the chain 22 passes upon a first idler pulley 26 upon the front panel slightly beneath the shelf 17 a , above the left sprocket 20 and inwardly from the center of the left sprocket . also keeping tension in the chain or other flexible elongated member , a second idler pulley 27 has its position upon the front panel beneath the left sprocket 20 , outwardly from the center of the left sprocket , and outwardly from the first sprocket . the two idler pulleys have sufficient biasing strength , maintaining the chain 22 taut during initial mixing of material , the time of maximum load , and later during continuous mixing , a time of lesser load upon the driving mechanism . the chain continues around the second idler pulley and turns the gear 23 connected to a screw conveyor . outwardly from the screw gear , the screw shaft also has a drive gear 23 a with a larger diameter than the screw gear and a higher tooth count . this drive gear 23 a receives the drive chain 24 that delivers the power from the motor &# 39 ; s drive sprocket 25 . the hydraulic motor secures to the leg 3 a and the left bottom 6 a as shown . the enclosure rests upon the other legs 3 and the base 2 . fig8 a provides an alternate embodiment of the driving mechanism where the left mixer connects to its sprocket 20 and the right mixer to its sprocket 21 outwardly of the front panel 17 . the two sprockets have the largest diameter as shown . the sprockets rotate by the action of the chain 22 or other flexible elongated member , in opposite directions . the opposite rotation occurs as the chain 22 passes upon a first idler pulley 26 located upon the front panel between two shelves 17 a towards the left side panel 16 , above the left sprocket 20 and inwardly from the center of the left sprocket . also keeping tension in the chain or other flexible elongated member , a second idler pulley 27 has its position upon the front panel beneath the left sprocket 20 , inwardly from the center of the left sprocket and the first sprocket . the chain continues to a third idler pulley 27 a partially shown in this figure behind drive gear 23 of the conveyor . the three idler pulleys have sufficient biasing strength , maintaining the chain 22 taut during initial mixing of material , the time of maximum load , and later during continuous mixing , a time of lesser load upon the driving mechanism . the chain continues around the third idler pulley and turns a gear sprocket 23 a connected to the screw conveyor but concealed behind the drive gear 23 . the chain then travels from the gear sprocket to the sprocket 21 for the right mixer . outwardly from the gear sprocket 23 a , the screw shaft also has the drive gear 23 with a larger diameter than the gear sprocket and a higher tooth count . this drive gear 23 receives the drive chain 24 that delivers the power from the motor &# 39 ; s drive sprocket 25 as shown before . fig8 b shows the gearing and chain proximate the front panel 17 with the drive gear 23 and drive chain 24 removed . as above , the chain 22 begins its travels upon the first idler pulley 26 and proceeds above the left sprocket 20 and inwardly from the center of the left sprocket . the chain proceeds around the inner teeth of the left sprocket towards the second idler pulley 27 which is beneath the left sprocket and inwardly from the center of the left sprocket and the first sprocket . the chain continues to a third idler pulley 27 a spaced inwardly from the second idler pulley upon an idler arm 27 b . the third idler pulley is located upon the free end of the idler arm 27 b while the second idler pulley is upon the pivoting end of the idler arm . the idler arm &# 39 ; s pivoting end and the second idler puller are generally proximate the gear sprocket 23 a . the pivoting end of the idler arm secures to a post 17 b upon the front panel . the post is generally perpendicular to the shelves 17 a and upon the exterior of the front panel as shown . the chain continues around the third idler pulley and turns the gear sprocket 23 a so that the screw conveyor turns . the chain then travels from the gear sprocket to the sprocket 21 for the right mixer and back to the first idler pulley . the three idler pulleys in cooperation with the idler arm provide sufficient biasing to keep the chain 22 taut during initial mixing of material , maximum load of material , and during lesser load upon the driving mechanism . turning the invention again , fig9 shows the invention from a side view with the top panel , drive cover , and motor cover removed . this figure has a similar appearance to fig3 but here showing the drive mechanism from the side . as mentioned above , the driving mechanism turns three components simultaneously to mix product in a hopper , enclosure of this volume . fig1 shows the three components and the remainder of the invention from above . the driving mechanism supplies power from the motor 14 through the screw gear 23 to a screw conveyor 28 , then the right sprocket 21 to the right mixer 19 , and then the left sprocket 20 to the left mixer 18 . the screw conveyor 28 has its position within the bottom 6 of the enclosure 4 , generally centered , and a distance above the junction of the two edges of the v shape described above . the screw conveyor includes helical flights at a regular interval and arranged to advance material axially , along the screw conveyor . the flighting , as at 28 a , has a construction of a coiled bar of metal wrapped around a shaft 28 b . during usage , an operator directs the screw conveyor in clockwise rotation to mix the material and move it away from the dispensing outlet , that is , towards the front panel . then for dispensing of material , the operator reverses the direction of the screw conveyor , that is , counterclockwise , which moves the material toward the outlet 11 , dispensing it into a feed bunk . the helical flights have an outer diameter that fits within the bottom panels as at 6 . for this volume of hopper , the invention has at least one paddle mixer above the screw conveyor . though fig1 shows two paddle mixers , the applicant foresees that the invention may operate upon a single paddle mixer in an alternate embodiment . meanwhile , the two paddle mixers , 18 , 19 always move the feed in the opposite direction from the screw conveyor , producing two dimensions of mixing . the paddle mixers mix the material where one , 18 , turns clockwise while the other , 19 turns counterclockwise , the paddle mixers counter rotate . each paddle mixer has a plurality of paddles arranged thereon . each paddle , as at 29 has a generally t shape with a wide , rectangular plate 29 a parallel to a plane including the length of the mixer shaft , and a thin rounded stem 29 b generally perpendicular to the mixer shaft . each paddle mixer may have paddles 29 in select arrangements . here , the right mixer 19 has paddles in a primary arrangement 30 and a secondary arrangement 31 . the primary arrangement has paired paddles in opposition with the plates 29 a generally at an angle to the shaft , particularly towards its length or longitudinal axis . the angle of the paddles , particularly the plates , is from about 15 ° to about 75 °. the secondary arrangement has paired paddles in opposition but with the plates pitched at the mirror image to the plates of the primary arrangement , that is , from about 75 ° to about 15 ° to the shaft , particularly towards its length or longitudinal axis and opposite that of the plate on the other side , forming an x shaped pattern as shown . here , the right mixer has three primary arrangements between four secondary arrangements of its paddles in an alternating manner which produces an axial movement of the feed , often grain . opposite the right mixer , the left mixer 18 has seven secondary arrangements of its paddles . in another embodiment , the invention has produced optimal flow of feed utilizing paddles at a 45 ° angle to the shaft . therefore , while in mixing mode of the invention , the left mixer and the right mixer , through their paddles , drive the material or feed , longitudinally , toward the dispensing outlet , that is , the back panel 9 of the hopper and the screw conveyor drives it away from the dispensing outlet towards the front panel 17 . when the feed reaches the front panel 17 , the conveyor discharges the feed against the bottom 6 and its portions 6 a , 6 b with their approximately 45 ° upward angle , shown in fig2 , 3 , 8 . the paddle mixers counter rotate and in mixing mode raise feed in the center of the hopper and lower feed on the outside of the hopper . the feed then travels upwardly on the bottom portions until the paddle mixers , 18 , 19 collect the feed and move it towards the back panel . upon engaging the back panel , the feed drops into a void created by the screw conveyor and the mixing cycle repeats . while in the mode of dispensing feed from the invention , the left mixer and the right mixer , through their paddles , continue mixing , but they drive the material away from the back panel towards the front panel . the screw conveyor , though below the paddles , therefore conveys the feed in the opposite direction , that is , toward the back panel , and out the dispensing outlet . the paddle mixers and the screw conveyor rotate in the opposite direction as in the mixing mode . in an alternate embodiment , the present invention includes switches and wiring from the device to a remote location , such as the cab of a host vehicle or truck . the switches are foreseen to control rotation and direction of the mixers and the conveyor either jointly or singly . the screw conveyor and the left mixer and the right mixer turn using a hydraulic motor 14 coupled by a chain dive 24 , 22 . the prior art hoppers typically utilize dc electric gear motors . the present invention uses hydraulic actuated motors to meet the greater horsepower requirements of the mixing action . few hoppers in the prior art use a paddle style mixing screw as in the present invention . and fewer prior art hoppers , if any , drive their conveyors and paddles in one direction to mix and the opposite direction to dispense as in the present invention . from the aforementioned description , a vehicle mounted feed hopper device has been described . the vehicle mounted feed hopper device is uniquely capable of mixing feed materials , excluding silage , in a hopper less than 101 cubic feet while attaining blends suitable and nutritious for livestock . the vehicle mounted feed hopper device and its various components may be manufactured from many materials , including but not limited to , wood , steel , aluminum , polymers , polypropylene , polyvinyl chloride , high density polyethylene , polypropylene , ferrous and non - ferrous metals , their alloys , and composites . various aspects of the illustrative embodiments have been described using terms commonly employed by those skilled in the art to convey the
