(54) GRAIN COMBINE

I

FIELD: agricultural engineering.

A combine harvester is known that includes an inclined chamber, a threshing apparatus with a straw walker, a bunker and a device for cleaning grain from small impurities (1.

A disadvantage of the known combine is the impossibility of turning the beveled mass or rolls with partial separation of the grain and further laying the dried mass in the roll. IQ

The aim of the invention is to reduce grain losses and accelerate the drying of the roll.

The goal is achieved by the fact that the threshing machine with a straw is made in the form of a agitator containing a series of finger drums and a row of 15 baffles installed above them, while the combine is equipped with an additional sieve installed under the agitator and additional fans installed under the additional sieve .

The drawing shows a combine harvester.

It includes header 1 with reel 2, pick-up 3 mounted in front of the header,

screw 4, floating conveyor 5 installed in inclined chamber 6, receiving beater 7, agitator 8 containing a series of finger drums 9 and a row of demolition beaters 10, a sieve 11 installed under the agitator, a device for cleaning grain from fine impurities, including two the sieve 12 and the fan 13 installed under the sieve 11, the additional fans 14 and the hopper 15.

Works combine harvester as follows.

The mowed header 1 is picked up by the pick-up 3, the mass is fed by the screw 4 into the inclined chamber 6. The floating conveyor 5 transports the mass to the receiving beater 7, which feeds it to the chopper 8. The rotation speed of each subsequent drum drum 9, rotator is greater than the speed of the previous one. The grain released during the turning of the mass is fed to the sieve 11, and then to the sieve 12, from where the final cleaned with the help of the fan 13 is sent to the bunker. 15. The mass passing through the agitator is blown by the air flow from the additional fans 14, while partially

dried and then laid in a swath on the stubble for final drying, after which it is subjected to a final thresh.

Due to this design of the combine harvester, it is possible to reduce grain losses due to its partial release while agitating the mass, partial drying of the whole mass in the combine, and if necessary, the roller can be passed several times through the agitator, thus achieving the optimal domolization of the final dried roller.
