Description

The present invention relates to a nested cell with a cellular sowing apparatus and with a rotary valve installed in the cavity of the seed conduit. In the proposed plant, the periodic deflection of the rotary valve, in order to release the seeds to the bottom of the furrow, is carried out using the projections of the seed drum.

The frame 4 of the crop shown in the drawing is fixed by means of part 3 on the semi-axles 2 of the running wheels 1, a gear wheel 5, which engages with the gear wheel b, transmitting the rotation through the gear wheels 7, 8 gear wheels 9 is attached to the hub of one of the wheels 1 -12 gearboxes. Gears 7, 8, together with their axles, can have a longitudinal movement under the action of a lever in order to alternately activate one of the gears 9-12 of the gearbox. From the latter, rotation is transmitted through gear 13 to the gear wheel 14, which sits on the same axis 15 with the seed drum 16, which is mounted in the sides of the casing 17. This casing is attached to the seed box 18 having a lid 2Q, which in turn is fastened with bolts 19 The main frame 4 is attached to the wall of the casing 17. A seed wire 21 is attached, the front side of which serves as a valve 22.

may take a vertical position due to its hinged fastening on the axis 23. The rotary valve 22 may deflect to pass the seeds under the action of either its own weight or the weight, or the spring 48 supported by the bracket 24 secured to the bracket 25.

In the seed box above the seeding drum 16 is placed a cap 26. against which is located an agitator 27 with paddles 28. The agitator is fixed on the axis 29 and is rotated from the gear wheel 14. On the front of the frame 4 there is a bracket 31, to which corner 33. and brackets 34 pivotally attached leads 32 openers. Behind the coulters 35, at the ends of the leads, on the axis 39, the roller 37 is fixed. It can move in the cuts 38 of the lead, due to which it is possible to embed the seeds at different depths. To lift the coulters, there is a lever with a finger 42, which, when the lever is lifted up, rests on the pin 43 and lifts the coulter. The lifting mechanism is connected to the gear box, which is turned off when lifting the coulters, thereby stopping the operation of the sowing unit.

When rotating the seeding drum 16 in the direction shown by the arrow.

27 seeds pushed by the agitator fall into the grooves 44 of the drum. From the latter, the seeds are ejected into portions 21 in portions, and case 47 prevents the seeds from falling out of other grooves.

Upon further rotation of the drum, the protrusion 45 emerges from the joint with the valve shoulder 46, which thereby opens up, and the seeds all immediately fall into the furrow made by the vomer. Behind the coulter comes a skating rink, which on top is filling the seeds with earth. The seed embedment depth can be adjusted by strengthening the roller in slots 38 higher or lower relative to the vomer.

The subject matter of the invention.

Breeding cell with a cellular sowing device and with a rotary valve located in the family cable, characterized in that for the periodic deflection of the valve 22 against the action of a special load, the dead weight of the valve or spring, the protrusions 45 of the sowing drum 6, " l interaction with which valve 46 is intended.
