Abstract

The invention relates to agricultural machinery, in particular to coulters, which can be used in crops for a wide spread method of sowing seed crops and fertilizing. The aim of the invention is to improve the uniformity of the distribution of seeds and fertilizer in the bands. The centurion for spreading the seeds and fertilizing, contains a hollow rack 2, an arrowed paw 1 and a distributor located in its lower part. The latter is tapered and screwed along the vertical axis 5 of the rack in the form of a self-rotating upper cone 3, along the perimeter of which curvilinear plates are placed 6 with an inclination angle coinciding with the inclination angle of the lower helical stationary snake rigidly connected to the opener walls and the vertical axis of the cone, the surface of which consists of multi-way more expensive treadmills k, separated from each other by small protrusions, and extending into the rear notch of the hollow stand of the opener, while providing uniform strip seeding of seeds and fertilizers. 2 Il. i (L

The invention relates to agricultural machinery, in particular, to coulters, which can be used in seedlings for a spreading method of sowing crops and fertilizing.

The purpose of the invention is to increase the uniformity of distribution of the seeds and fertilizers in the lanes.

FIG. 1 shows the opener, general view; in fig. 2 shows section A-A in FIG. 1 (the band distribution of seeds and fertilizers when operating as an opener).

The opener consists of a lancet paw 1, a hollow pillar 2, the upper conical part 3 of the distributor and the lower fixed-screw snake 4 of the distributor. The cone part 3 of the distributor consists of a cone with a vertical axis 5, along the perimeter of which curvilinear plates 6 are attached with an angle of inclination coinciding with the angle of inclination of the screw snake. The fixed-screw part A of the distributor is fixed to the hollow drain of the opener 2 and to the vertical axis of rotation of the upper conical-screw part 3 of the distributor. Surface

The mixtures fall on different treadmills of the lower fixed screw part 4 of the distributor, where, due to the difference in the surface properties of the particles of the heterogeneous grain mix, they are redistributed and exit through the notch in the rear section of the hollow rack 2 on the hard bottom formed by the moving arrow. Coarse grains are sown in zone 9 (Fig. 2), medium sized grains and whole fertilizer granules in zone 10 and crushed fertilizer particles in zone 11.

Invention Formula The opener for wide sowing of seeds and fertilization, containing a pointed blade, a hollow stand, and a distributor located in its lower part, characterized in that the distributor is made conical-screw in which the spreader seeds are planted the cone is mounted on a fixed vertical axis with the possibility The fixed-screw part 4 of the distribution of rotation, relative to the bottom, is made up of multi-way treadmills separated from each other by small protrusions 7 and extending into the lower rear cutout 8 of the hollow rack 2 of the opener. When working with the lap coulters of the proposed design, a grain mix is fed to the upper movable conical part 3 of the distributor along the hollow legs of the 2 openers. Rotating, part 3 gives different kinetic energy to the particles of the grain mixture. With this, the components screw-in part and provided around the perimeter of the curvilinear plates with an angle of inclination coinciding with the angle of inclination of the screw snake, which is rigidly connected to the walls of the stand and the fixed vertical axis of the distributor, while in the rear wall of the rack there is a cut-out for the output of the snake screw tracks. 1
