Description

The invention relates to agricultural machinery, in particular to devices feeding threshing aggregates of combine harvesters.

Known thresher feeder, made in the form of an inclined hollow body with a smooth bottom. A chain-slat conveyor is located inside the casing, which transfers the bread mass cut by the cutting apparatus from the header to the thresher (1).

Such a feeder does not provide a uniform feed, since the chain-slat conveyor moves the grain mass in the form in which it comes from the header auger.

Known accepted by the authors for the prototype feeder containing a hollow body with a smooth bottom and a number of rotors with flexible blades mounted inside the body of the feeder (2).

However, even this feeder is not able to provide uniform loading of the thresher, especially when harvesting long-stalked, lodged, confused breads, since under the action of a thick layer of mass, the elastic blades bend and work not on the edge, but on a curved surface, which significantly reduces their gripping ability and transporting activity , since in this case, the blades can slip on the stems of the transported mass.

The purpose of the invention is to increase the stability of the technological process of feeding bread mass into the thresher of a combine harvester by improving the transporting ability of the working bodies of the feeder.

This goal is achieved by the fact that in the feeder of the thresher of a combine harvester, which includes a housing of an inclined chamber with a smooth bottom and beaters equipped with pins and located inside this housing, at least one, first, receiving beater, cutting elements are installed alternately with pins.

Another feature of the invention is that the axis of the pins are offset relative to the axis of the beater forward in the direction of rotation.

Another feature of the invention is that at least one, the last, beater is equipped with conveying blades.

The invention is illustrated by the drawing, which shows a thresher feeder in the form of an inclined chamber of a combine harvester.

The feeder contains a hollow body 1 with a smooth bottom 2 and a series of pin beaters 3, 4 and 5 sequentially located in its cavity. The last beater 6 is equipped with conveying blades 7. Moreover, for example, the first beater 3 is equipped with pins 8 and cutting elements 9 arranged alternately with pins 8. The pins 8 are made in the form of conical fingers or other special shapes, and the cutting elements 9 are in the form of segments with sharpened working edges 10 to ensure cutting of the technological straw mass. Pins 8 are mounted on beaters 3, 4, and 5, the axes of which are offset relative to the axes of the beaters forward in the direction of rotation by the value “K” to ensure that the mass glides along the pin when it leaves the straw mass and transfers this mass to the next bit.

The feeder operates as follows.

The chopped bread mass from the header is fed to the first, receiving bit 3, which moves it to the next beaters 4, 5 and 6 along the smooth bottom 2, and the last beater 6 sends this mass to the threshing unit.

When harvesting long-stalked, laid-down breads of high productivity, for example, when harvesting rice, tangled, moist, difficult to transport and interwoven stems enter the feeder, which the first beater 3 captures with its pins 8, moves them, and the cutting elements 9, installed alternately with the pins, tangled stems are cut, which contributes to the uniform and continuous transportation of this mass.

Beaters 4 and 5 pierce the mass with their pins 8, additionally tear the tangled stems and move them along the feeder to the bit 6, which contributes to the uniform supply of this mass. The last beater 6, equipped with blades, directs the mass into the threshing unit.

The positive effect of the device is to equalize the flow entering the threshing unit, increase the productivity of the combine by increasing the uniformity of loading the thresher when the combine is working in fields with different heights of stalks, heavily laid, confused and high-yielding breads, reducing the occurrence of clogging of the working bodies of both the feeder and others working bodies of the harvester as a whole.

The invention can find wide application in combine harvesters, especially when harvesting high-yielding confused, wet bread and rice.
