Description

The proposed row seed, intended for sowing at a shallow depth, has a special sowing unit device, regulating the seeding density, and is equipped with special-purpose coulters, allowing the seed to be applied to uneven fields. In FIG. 1 shows, in schematic form, the cross section in vertical section; FIG. 2 is a front view of the metering unit. The proposed range of the cutter has, in the slot of the bottom of the crate 1, a roller 2 (FIG. 1) with Grooves 7 (FIG. 2) driven from the axis of the traveling wheels; parallel to the roller and close to it is a sloping plate 3 (. 2), cn "chbzhsnna cutouts For, when-xc actions against cannzhzh 7 roller and about (h) on the other hand to transfer the seed from the box to this wire b ( Fig. 1) during the rotation of WA.ik. For adjusting the seeding density, there are adjustable shutters 5 (FNI. 1 N 2), overlapping in some way or another the cutouts and the grooves 7. The syringe NIKI is made in the form of hollow boxes 4, equipped with frame 8 and mounted on the rotary 9 around the hinges 9 levers 10, the ends 11 of which are loaded with springs 13. The subject of the patent. 1. An arbor of a tractor, characterized in that its coulters are mounted on levers 10, pivoting near hinges 9 and loaded with springs 13, in order to adapt the coulter to uneven ground surfaces. 2. The form of execution indicated in the plant, characterized by the use of the sowing apparatus consisting of a roller 2 installed under the seed box 1, provided with grooves 7, and | an inclined plate 3, located with its notches behind against the grooves of the roller in order to form outlets for the grain fed in, for blocking which holes, | For the purpose of adjusting the seeding density, the adjustable flaps 5 are used.
