Assessment of prospective technological schemes potato harvester
The article considers the issue of expanding the range of soil and climatic conditions for effective operation of potato harvesting machines through the introduction in the technological scheme of the developed technical solutions allowing to intensify the process of separation of tuber piles and to reduce damage of tubers during interaction with metallic surfaces of the frame when hitting the surface of the vehicle body during unloading of the storage bin. The descriptions and operation of the developed devices: mines, for part of the potato harvesters developed by digging up working body, for bodies posevnoi separation was developed by levelling the intensifier with elastic working elements mounted on the working branch of the paintings in the front part of the bodies external separation intensifiers developed in the form of pneumatic cylinders clonearray, to limit the interaction of potato tubers with the metal side surfaces of the combine body on the side surfaces of the conveyors of the sieving and external separation bodies, limiters in the form of elastic elements were developed, to reduce the speed of the falling tubers and to reduce the height difference between the unloading conveyor and the body of the vehicle, a device was developed to extinguish the energy of the falling potato tubers. The results of comparative tests of serial and improved potato harvesting machines are presented. In conclusion, it is concluded that the range of effective use of the developed devices is expanded.
