FIELD OF THE INVENTION The invention relates to agricultural machinery, mainly to machines for the harvesting of standing crops.

A device for lifting and threshing lodged plants on the root is known, which contains a combing device, two pneumatic channels, one of which is located in front of the combing drum for lifting the laid stalks, and the other is installed behind the combing device to supply the stalks to the combing device and transport the combed heap 1.

However, this device does not allow for the necessary entry of the combing device into the grain mass; high quality tow of mixed up, laid plants due to the absence of a compact tuft of ears for their passage in the combing gap between the fingers. In addition, the grains after stripping move under the action of centrifugal force along the surface of the finger to its end, and part of the grains are thrown past the drum, and the air flow pulls the panicles out of the stripping area.

It is also known a device for threshing agricultural crops at the root, containing a drum mounted rotatably with a casing placed above it and with combing teeth located along the drum 2.

A disadvantage of the known device is the loss of grain when harvesting laid bread, caused by insufficiently compact formation of a bunch of ears and a sharp impact on the bunch by one brown teeth, as well as the absence of blown grain from the teeth.

The purpose of the invention is to reduce the loss of grain during the harvesting of laid bread.

The goal is set for 1a in the device for threshing agricultural crops at the root, which contains a drum mounted for rotation with a casing placed above it and with combing teeth installed along the drum, the latter being located two light blue, with the upper Russian teeth having a clearance between the teeth are bigger than the bottom, and inside the drum there is a diametrical fan coaxially with it to blow the pile off the teeth.

Moreover, the casing is provided with an additional diameter fan for lifting.

and the supply of laid stalks to the area of towing, installed in front of the drum.

FIG. 1 shows a device for threshing agricultural crops at the root, side view; in fig. 2 - teeth, located two runes.

The device comprises a frame on which the drum 1 is rotatably mounted with combing upper 2 and lower 3 teeth, those located

two runes and rows, a casing 4 placed above the drum 1, a cutting apparatus 5 with a conveyor 6, a bunker 7 with a conveyor 8. Inside the drum 1 there is a diametrical fan 9 coaxially with it to blow away the heap from the teeth. Casing 4 has

additional diametrical fan 10 for raising and feeding the laid stalks to the nozzle area, mounted in front of the drum 1. The upper 2 and lower 3 teeth may have different lengths, but the upper 2

already in width in relation to the lower 3 teeth of m.

The device works as follows.

When driving on a field rotating

drum 1 combing the top 2 and bottom 3 teeth captures tufts of stems. Two brown teeth enter the grain-to-white mass and the upper 2 teeth, having a large gap between them, pre-form a compact bundle of stems and perform partial stripping. The lower teeth 3 have a smaller gap between them and complete stripping of the stems. In this case, the heaped pile is collected in the space between the upper 2 and lower 3 teeth. Diametrical

The fan 9, mounted in the drum 1 coaxially with it, creates a discharge air flow, which, passing through the drum 1, blows the combed heap from the teeth. An additional diametrical fan 10, creating an air flow inside itself, provides the latter with the rise and supply of laid stems to the stripping area. The air ducts of both fans transport the combed heap into the bunker 7, where it is unloaded by the conveyor 8. The cutting unit 5 cuts off the stems and leads them to the side by the conveyor 6.

Thus, this solution will reduce the loss of grain when harvesting laid bread.
