Description

Threshing devices, for example, to a combine, with the use of conveyors for removing the threshed mass from the threshing drum are known.

Distinctive feature

The proposed threshing device is that the receiving ends of the two conveyors are arranged in such a way that the mass ejected by the drum is divided into two parts, of which the large straw part comes to the upper conveyor and the fine straw breaker to the lower conveyor.

The drawing shows a general view of the combine in section.

Threshing grain crops is carried out as follows.

The solomist mass, which emerges from the drum along the thickness of the layer, is divided into two parts: the upper part, preferably the long straw, falls on the chain-slat conveyor (straw walker) 4 of the upper zone; the second part, which is smaller, being located during the threshing process in the drum, mainly in the lower part of the layer, is highly saturated with grain, falls on the conveyor 2 of the slat type in the lower zone.

Subsequently, the threshed mass, 1 by the conveyor 4 in the direction of exit from the thresher, has the opportunity, due to the rise of the beaters and other organs, to allocate grain and small chaff to the lower zone of the Tracyorter 2, due to their spilling between the conveyor slats.

The operation of the lower zone consists in the fact that most of the threshed grain immediately after it leaves the drum lies on the slats of the conveyor 2, from where it goes directly to the first cleaning mill. Part of the straw carried by the conveyor 2 is removed from it by ikierny rollers as it is on conventional combine harvesters and transferred by them to the lower chain-fed conveyor. Thus, the straw is divided into two independent parts - the upper part along the conveyors 4 and 5 lower along the conveyors 2 and /.

Grain and chaff, spilled between the slats of the conveyors 4 and 5, fall into the lower zone on conveyors 2 and 1, and spilled between the slats of the conveyor 1 are carried along by the lower branch of the latter along the pitched one to the first clearing camp,

To prevent the grain from creeping from the second cleaning sieves and falling on the .JOMbi layer moving to the exit of the thresher, a grain-assisting screw 3 is provided, which diverts the captured grain to the cereal-transporter for re-separation or domolot.

The subject of the invention is a Threshing Spray, for example, to a combine using

of conveyors for threshed mass from threshing} 101o drum, which is the fact that the receiving ends of two tralsportero :; They are arranged in such a way that the mass ejected by the drum is divided into two parts, with the crinnolomist going to the upper conveyor, and the mild strawberry to the lower conveyor.
