Description

The invention relates to agricultural machinery, in particular to structures for cleaning combine harvesters. The purpose of the invention is to improve the quality of separation. The cleaning contains a grating board 1 with a comb installed on its end, which has longitudinal fingers 2. To improve the separation of grain from the pile, fingers 2 are attached to the board 1 pivotally. Under the comb mounted horizontal drive shaft 3 with Cams 4. located 'opposite fingers 2, and agitators 5 installed between the cams 4. When working, the pile falls on the agitators 5, shaken them, resulting in improved separation of grain from the pile. Under the action of the cams 4 fingers 2 make oscillatory movements, agitating and fluffing up a pile, which contributes to a better separation of the grain. 4 il.

The invention relates to agricultural machinery, in particular to the structures of cleaning combine harvesters.

The purpose of the invention is to improve the quality of separation.

FIG. 1 shows the proposed cleaning. general form; in fig. 2 - the same. view from above; in fig. 3 is a section A-A in FIG. 2; in fig. 4 section bb in Fig.2.

Cleaning combine harvester contains a grating board 1 with a comb installed at its end, having longitudinal fingers 2. Fingers 2 are hingedly attached. Under the comb mounted horizontal drive shaft 3 with the Cams 4, located opposite the fingers 2, and the neighboring Cams 4 are offset from each other in phase. On the shaft 3, in the intervals between the cams 4 and the fingers 1, the turners are installed in the form of rods perpendicular to the shaft 3 5. A fan (not shown) is located under the board.

Cleaning combine works as follows.

When the combine moves, the threshed mass enters the shaker plate 1 and comes down onto the finger comb. The turners 5, rotating on the shaft 3, actively affect the heap, take it away! it and thus violates the connection between its lower and upper layers, raise a heap, shaking it, and lower it further on

5 fingers 2. As a result of the separation of the mass of the heap, there is an additional release from the heap of grain or seeds located in its lower part.

Depleted grain and seed mass

10 under the influence of the air flow of the fan and the oscillatory movements of the fingers 2, which are affected by the cams 4, are listening more actively, which contributes to the selection of the masses remaining in it

15 seeds and grains.

Claims

Invention Formula Cleaning a combine harvester containing a shaker board with an installed

20 at its end with a comb equipped with fingers, a fan and a sieve mill, characterized in that, in order to improve the quality of separation, the fingers of the comb are hinged and equipped with a swing mechanism made in the form of a shaft with cams interacting with fingers, while adjacent cams phase shifted relative to each other, and between the fingers on the shaft are installed · turners.
