COMBINE FOR HARVESTING STANDING CEREAL CROPS

摘要

FIELD: agriculture. ^ SUBSTANCE: invention relates to agricultural machine building. A combine comprises a transport facility with a threshing unit and a facility to move threshed grain along a tubular conveyor. A threshing unit comprises an assembly of forward-flow threshing chambers in the form of a pair of rollers with pneumatic throwers per each pair of rollers. Downstream the threshing chambers there is a knife drum for cutting and grinding of plants, which are thrown around the field or are loaded into a vehicle. Drive of the forward-flow threshing chambers with pneumatic throwers is done from a hydraulic motor. The knife drum drive is carried out via a conical reducer from a power takeoff shaft. ^ EFFECT: using the developed combine design helps to increase labour efficiency and to reduce power intensity of harvesting. ^ 2 dwg
