with continued reference to the drawings , a tobacco harvester 10 is provided having a frame 11 on which a raised deck 12 is mounted . the frame 11 is supported by a front propelling wheel 13 and a pair of rear wheels 14 . the propelling wheel is driven by a power plant 15 and is controlled by a steering mechanism including a steering wheel 16 mounted on the deck 12 . preferably , a conventional row guide mechanism 17 is connected to the front wheel 13 to maintain such front wheel in a furrow between rows of tobacco plants so that it is not necessary for a driver to steer the harvester at all times . a pair of aligned seats 18 are suspended from the frame 11 at each side of the harvester in any desired manner so that the seats are located between rows of tobacco plants and may be disposed adjacent to the ground . if desired , the seats 18 may be vertically adjustable relative to the ground so that such seats are located adjacent to a particular portion of the tobacco plants . a plurality of generally vertically disposed endless conveyors 19 are supported on the frame 11 and the lower end of each conveyor is located adjacent to one of the seats while the upper end is disposed above the deck 12 . an endless belt 20 engages the upward run of each conveyor 19 so that a workman , who is sitting on a seat 18 , can prime tobacco leaves and place the leaves between the conveyor 19 and the belt 20 and such leaves are carried upwardly to a position above the deck where they are discharged from the conveyor . the conveyors 19 and belts 20 are driven in any conventional manner , as by chains and sprockets driven by a drive shaft 21 which in turn may be driven from the power plant 15 or by a sprocket fixed to one of the rear wheels 14 . at the rear of the frame 11 , a selectively operated lift mechanism 22 is provided for raising a pair of lift tines 23 or a platform from the ground to a position above the tobacco plants . as illustrated , the lift mechanism includes vertically disposed guide members 24 mounted on the frame 11 and in which a carriage having the tines 23 connected thereto is vertically movable by a bell crank 25 operated by a fluid cylinder 26 . it is noted that the lift mechanism 22 can be raised and lowered by any other conventional lift mechanism . the structure thus far described is shown in my prior u . s . pat . no . 3 , 215 , 288 . above the deck 12 a pair of opposed inwardly and downwardly inclined slides 30 are mounted in any desired manner at opposite sides of the deck and between the forward and rearward vertically disposed conveyors . as illustrated , the forward conveyor 19 discharges the tobacco leaves rearwardly , and the rearward conveyor 19 discharges tobacco leaves forwardly so that leaves from both conveyors at each side of the harvester are discharged onto the upper portion of one of the slides 30 . a pair of generally longitudinally disposed conveyors 31 are mounted on the upper surface of the deck 12 with the forward portion of each conveyor being located directly below the lower end portion of one of the slides 30 . each of the conveyors 31 includes a drive roller 32 carried by a shaft 33 which is rotatably mounted in lugs 34 mounted on the deck 12 . an endless belt 35 drivingly engages the roller 32 and extends upwardly and rearwardly about an idler roller 36 mounted on a shaft 37 which is rotatably carried in a support frame 38 . the conveyor belt 35 preferably has a plurality of laterally disposed slats 39 which support the tobacco leaves , and , if desired , the belt 35 may be either imperforate or foraminated . also , it is contemplated that the belt 35 could consist of two or more strips having a plurality of slats 39 connected thereto . the drive roller 32 may be driven in any desired manner such as a sprocket ( not shown ) which is fixed to the shaft 33 and is connected by a chain 40 to a sprocket fixed to the drive shaft 21 ( fig4 ). a large bulk tobacco receiving container 41 is carried on the tines or platform 23 at the rear of the deck 12 and adjacent to the discharge end of both of the conveyors 31 . the upper side of the container 41 is open and such open side is disposed below the upper run of the conveyors so that tobacco leaves discharged from the conveyors 31 fall into the container where at least most of the leaves are disposed in a flat plane . in the operation of the device , a workman / driver on the deck 12 steers the harvester 10 to a field of tobacco plants having at least some leaves which are mature enough to harvest . at the field , the driver aligns the harvester so that the front wheel 13 is disposed along a furrow between rows of tobacco plants and the rear wheels 14 are disposed along adjacent furrows . one or two workmen or primers sit on the seats 18 at each side of the harvester and as the harvester moves through the field , the primers select and remove desired leaves from the tobacco plants . the primers may place each individual leaf between the vertical conveyor 19 and the endless belt 20 which is adjacent to him or he may accumulate several leaves before placing them on the conveyor . the conveyors 19 and belts 20 are operating continuously and lift the leaves to the upper end of the conveyors where such leaves are discharged onto the slides 30 . the leaves gravitate or slide downwardly and inwardly along the slides 30 and are discharged onto the upper runs of the conveyors 31 . the conveyors 31 are operated continuously with the upper run being inclined upwardly and rearwardly so that when the tobacco leaves are discharged onto the upper run , such leaves are raised to a height greater than the dimensions of the container 41 . at the rear end of the conveyors 31 , the tobacco leaves are discharged into the container 41 in a random haphazard manner with the stems disposed in any direction . however , most of the leaves fall flat into the container . when the harvester is in operation , the row guide mechanism 17 maintains the harvester in alignment with the rows of tobacco plants automatically so that periodically the workman on the deck may take a pitchfork or other pointed implement and spread the leaves within the container so that the container is substantially evenly filled and the tobacco leaves are disposed in the corners of the container as well as in the middle . preferably the harvester 10 travels at a speed of approximately one to three miles per hour through the tobacco field so that the primers may select and remove only the leaves which are mature enough for curing . when the harvester reaches the end of a row , the workman on the deck moves to the front of the harvester and operates the steering wheel 16 to cause the harvester to enter the rows of tobacco plants in an area adjacent to the area just traversed so that the priming operation continues . if the container is filled or substantially filled at the end of a row , the lift mechanism 22 is operated to drop the tines 23 and discharge the container 41 either onto a wagon or other vehicle for transporting the container to a barn for curing , or the lift mechanism may discharge the container onto the access roadway adjacent to the field for later removal to the curing barn . after the container 41 has been discharged from the lift mechanism , an empty container is placed thereon and raised to a height substantially equal to the deck 12 and above the tobacco plants in the field . thereafter the harvester re - enters the field of tobacco plants and the priming operation continues .
tobacco harvesting apparatus having a plurality of seats for workmen to hand prime tobacco plants and having a plurality of conveyors for transporting the tobacco leaves and discharging such leaves into a large bulk container .
