Description

(54) DISTRIBUTOR OF PLANTED MATERIALS OF PNEUMATIC GRAIN-THREE SEEDS

{

The invention relates to agricultural machinery, in particular to grain grooves with a pneumatic centralized seeding system,

A known distributor of grain materials for pneumatic seedlings includes an expanding socket, on the inner surface of which spherical reflector segments, dividers and connecting pipes are arranged in a staggered pattern.

Also known is a distributor of seeded materials of pneumatic grain-grain sprouts, including a supply pipe, an expanding socket, filled in the form of two lateral, lower and obliquely installed upper walls, with reflectors, flow dividers, discharge pipes and these wires 2.

The described distributors have a high uniformity of distribution of the sown ml: (pn.ii;) gfi relatively wide limits of change, if the air flow rate at the entrance to the distributor is in the range of 22-25 m / s. However, if the air velocity falls outside these values, then the average uneven distribution does not satisfy the agrotechnical requirements.

The purpose of the invention is poveplie uniform distribution of seed

10 material on this wire.

This goal is achieved by the fact that the side walls of the bell are filled with curvilinear ones and are installed by convexity inside the bell.

FIG. 1 shows the proposed distributor, side view; in fig. The same, with the upper wall removed, is a top view.

The distributor includes an inlet X of the pipeline 1, a socket 2, the states of the upper wall 3, the lower wall 4 and curved side walls 5, the reflectors 6, made on

Claims (1)

Claim Distributor of sowing materials of pneumatic grain-seeders, including the supply pipe, an expanding socket, made in the form of two side, bottom and obliquely installed upper walls. with reflectors, flow dividers, outlet nozzles and seed tubes, characterized by the fact that, in order to increase the uniformity of distribution of the sown materials along the seed tubes, the side walls of the bell are curved and set with convexity inside the socket.
