Description

the wall 5 in the upper part has a groove and is coupled with the shaft 2 of the coil 1 by means of an annular recess 3 and is enclosed by the fixed casing 8 of the receiving hopper. Partitions 7 are hinged on the axis

9 and the upper edges cover the sowing coil 1 with a gap. Between the partitions 7 and the side walls 4 and 5, preloaded springs are mounted on the axis 9

10 with equal parameters. The lower edges of the partitions 7 and the walls 4 and 5 of the receiving funnel are connected with the upper edges of the fixed partitions 11 and the walls of this wire 6 through elastic tapes 12.

Works as follows.

In order to decrease (increase) the seeding rate, coil 1 is pushed (pushed) into the socket and the size of its active part is reduced (increased). The movable side wall 5 is enclosed by a stationary casing 8 and in the upper part contains a groove that is movably mated with the annular recess 3 of the shaft of the coil 1. Such a connection between the shaft of the coil 1 and the receiving funnel with the wall 5 sowing to perform plane-parallel movement together with the shaft of the coil in the direction of its axis.

Between the partitions 7 and the side walls 4 and 6, preloaded springs 10 are installed on the axis 9. But the springs 10 have equal parameters, therefore when the wall-parallel movement of the wall 5 occurs, the distance between the partitions 7 decreases (increases) in proportion to the movement of this wall and for all channels remains the same . Thus, while decreasing (increasing) the seeding rate by decreasing (increasing) the coil solution, a synchronous reduction (increase) in the width of the channels formed by partitions 7 and walls 4 and 5 is ensured, and the seed flow is in any case divided into equal proportions parts of coil 1.

The lower edges of the partitions 7 and the walls 4 and 5 are connected to the upper edges of the partitions 11 and the walls of the wire 6 through elastic bands 12. As a result, equal portions of the seeds are transported from the receiving funnel to the channels of the wire 6 and further

into the opener screening chamber, which ensures that the goal is achieved.

In the proposed design, the uniform distribution of seeds over the cross-section of the seed wire, and hence the width of the opener, is achieved at any seeding rate and does not depend on the size of the active part of the coil.
