FIELD CATERPILLAR MACHINE Russian patent published in 2018 - IPC A01D41/02 A01D41/12 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to field machines for harvesting and collecting of not winnowed grain heap. Field caterpillar machine contains power source (1) with a caterpillar drive (2), a motor installation (3), a storage hopper. Storage hopper front part is articulated to the power source (1) frame (5), and the rear is supported with two hydraulic cylinders (6), located at an angle to each other. In the storage hopper rear part, the rear valve (7) is suspended on both sides of roof (26) with the possibility of its rotating in both directions relative to hinge (25), bottom and lateral sides of which are equipped with elastic bands, and its bottom part is held by the conveyor (9) plate (8), with elastic straps attached to it. Tracked vehicle front hitch (10) is accommodating reaper (11) with a reel (12), cutting device (13) and auger (14), rotary threshing and separating device (15) with bread mass tangential feeding, with a grinder (16) and a straw extractor (17), elevator (18) with flexible corrugated pipe (19) for grain heap transportation. On the power source (1) frame (5) on the side of the elevator (18) with a flexible corrugated pipe (19) a grain heap movement accelerator in the form of fan (20) is mounted, which bottom part is connected to the flexible corrugated pipe (19) free end. On the fan (20) cowl (21) confuser (22) with a swivel part (23) and apron (24) is made, between which a spacer (29) is articulated with possibility of horizontal rotation.

EFFECT: such constructive solution ensures the field machine operation under conditions of soil water-logging, grain heap compaction up to specific gravity of not less than 400 kg/m³ and a reduction in grain heap transporting cost to station, as well as the completeness of the storage hopper filling with a grain heap and reducing its losses when the hopper is full.
