FIELD MACHINE FOR HARVESTING AND COLLECTING GRAIN HEAP Russian patent published in 2017 - IPC A01D41/02 

FIELD: agriculture.

SUBSTANCE: field machine for harvesting and collecting the grain heap contains a power means with the front and the rear hitches. A header with a reel, a cutting device and a screw, a rotary threshing-separating device with a grinder and a straw outlet, an elevator with a flexible branch pipe and an inclined conveyor screw with a spiral and an unloading device are hung on the front hitch of the power means. A storage tank in the form of a hopper with a cone-shaped bottom is fixed on the rear hitch of the power means. The hopper has a grain heap compactor in the form of a vertical screw with the perforated helical surface of different diameters. In the middle, the helical surface has a diameter commensurate with the largest width of the hopper and evenly decreasing to the end of the screw. Under the vertical screw, there is an additional unloading screw of the hingedly connected horizontal and inclined parts for unloading the grain heap into the vehicle, which eliminates manual labour and increases the productivity.

EFFECT: compacting the grain heap before loading.
