FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in harvesting machines for small seed crops.

A device for collecting ergot horns, containing dividers, blade tines enclosed in enclosing casings, and receiving trays located under the tines 1, is known.

A device for stripping plants on the root is known, which contains dividers and longitudinal lobe tines arranged in pairs in a row, on which a casing 2 is mounted.

The disadvantage of these devices is a significant loss of seed yield due to spilling them into the gap between the feeders, which is necessary for the passage of the plants.

The purpose of the invention is to increase the completeness of the harvest of the grown seed by creating an effective airflow between the stripping zones.

The goal is achieved by the fact that the device for washing plants on the root is equipped with a suction confuser of a pneumatic conveyor with a double-face perforated fairing, turned upwards and installed above adjacent tapers of different pairs, while the edges of the fairing are convex.

In addition, the device is provided with elastic plates fixed to the ends of the sides of the fairing, to close the gap between the ends of the fairing and the cylindrical surface of rotation of the ends of the beater blades.

FIG. 1 shows a diagram of the proposed device; in fig. 2 shows section A-A in FIG. one.

The device contains dividers 1 mounted on frame 2 and blade tines 3-6 arranged in pairs in rows. Dividers 1 are installed in such a way that they close the front ends of tines 3-6 and cover the gap between tines 4 and 5. Top on frame 2 over beaters installed

a suction confuser 7 connected to a duct 8 of a pneumatic conveyor (not shown), in which a two-sided perforated fairing 9 is located over the adjacent beaters 4 and 5, facing upwards

upwards and having convex faces 10. Curvature of faces 10 of flap 9 is selected taking into account the distribution of power lines of the suction air flow in confusor 7, in addition, the execution of faces 10 of flap 9 perforated contributes to the effective convergence of the tow products from fairing 9. In addition, the speed of suction air flow must be greater than the critical speed of the nozzle products. Elastic plates U are fixed at the ends of the sides of the flap 9 to bridge the gap between the ends of the flap 9 and the cylindrical surface of rotation of the ends of the blades of the tines 4 and 5. The device operates as follows.

When the aggregate is moving along the rows, the plants with the dividers 1 are directed to the zones of towing between the beaters 3-4 and 5-6, which, rotating in the opposite direction, produce an intense weed of the seed pile and along the concave perforated facets of the fairing 9 or along the walls confuser 7 throw him into the zone of air flow, which through the channel

8 transports a pile to a storage bin (not shown). Through the perforated surface of the faces 10 of the flap 9, air is drawn in, which prevents the pile from hanging on the skirt 9. The elastic plates 11 prevent the seed pile from being thrown under the fairing 9. The device (not shown) is designed so that the tines 3 and 5 have left rotation, and beaters 4 and 6 - right.

The use of the invention will ensure maximum completeness of the collection of seeds.
