GRAIN COMBINE HARVESTER Russian patent published in 2013 - IPC A01D41/02 A01D41/133 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, namely, grain combine harvesters, performing harvesting of grains under increased humidity. The engine (7) of the harvester comprises a unit (3) of three pumps connected to the engine (7), an oil-liquid heat exchanger (4) and an air-liquid heat exchanger (9). The radiator pipes of the engine cooling system (7) are welded on the top to the rear wall of the hopper (15). The radiator pipes of oil cooling are welded in the lower front wall of the hopper (15). The radiator pipes (18) of the air cooling system are welded in the in the side walls of the hopper (15). The radiator pipes of the engine cooling system are welded on the top to the perforated bottom. On the bottom on the top two pressure sensors are placed, and on its bend there are impact sensors. At the bottom of the bottom a valve of contact dryer is mounted. The valve of contact and convective dryer is connected to the lower front wall of the hopper (15). In the side walls of the hopper (15) on the top the impact sensors are placed, and in the front wall of the hopper (15) there are pressure sensors. The bottom and top of the hopper (15) are connected by the recirculation pipe which is attached on the right to the fan (22), and on the left - the unloading pipe with a gate. The grain auger (2) is attached to the lifting screw (1) that is attached to the exhaust pipe (11) passing from the engine (7) turbocharger (10). Hollow shaft of the lifting screw (1) is open from the bottom, and on the top it has tangential windows. The lifting screw (1) is attached to the loading auger (12), which part of the outer wall is made in the form of the separating lattice. There is a unit of control (20) and signalling and the display (21) is located in the cabin.

EFFECT: technical solution enables to improve the efficiency of work of the grain combine harvester and to increase the coefficient of efficiency of its engine.
