The invention relates to agricultural machinery and can be used for harvesting grain crops.

on the vine.

The purpose of the invention is to increase the productivity and reduce grain losses.

FIG. 1 shows the proposed device, side view; in fig. 2 - comb, incision; in fig. 3 - comb in the open state; in fig. 4 - the position of the teeth of the parts of the dies at the time of batting; in fig. 5 - the same after brushing.

The proposed device consists of a conveyor 1 with combing working bodies mounted on it, made in the form of combs 2. Behind and below the device is closed by a casing 3 in which the auger 4 is placed. 2. The latter consists of two mating parts 6 and 7, one of which, for example, part 7 is rigidly fixed on the conveyor belt 1, and the other 6 relative to part 7 can move in the transverse direction. In the closed position, parts 6 and 7 of the comb 2 are returned under the action of a spring 8 mounted on the base of part 6 of the comb 2. At the end of each tooth of one of the parts from the side adjacent to

the tooth of the other part of the comb 2 is made protrusion 9.

The device works as follows. In ipouecce, work of comb 2 approaches to the zone of plant capture. The mechanism 5 for opening the gap between the teeth of the combs 2, overcoming the resistance of the spring 8, moves in the transverse direction part 6 of the comb 2 relative to part 7, with the result that a gap a is formed between the teeth (Fig. 3). In connection with the forward movement of the device into the formed gap E, the stroke is the stem of the plants. Upon further movement of the dies 2, part 6 11 is moved in the opposite direction by means of a spring 8, while the protrusion 9 closes the gap between the teeth, forming a closed slit b (Fig. 4).

Thus, the stem and plants, sandwiched between the teeth of the combs 2, are inclined on the conveyor belt 1 and stripped in a closed slot b. Moreover, the size of the gap between the teeth varies depending on the thickness of the plants and the thickness of the stem through the spring 8. The stripped grain falls on the conveyor belt 1 and is transported to the unloading screw 4. The gaps a 5 and b between the teeth of the combs 2 at the end of the comb completely overlap and The mating parts 6 and 7 of the combs 2 perform the function of the transporting bars.
