Description

(54) PLANTING DEVICE

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to seeding machines.

A disc-type seeder is known, which includes a seed hopper, in which a disk with holes around the hopper side is placed on the shaft with a circle and mounted on it on the opposite side is a turntable with a number of holes of different sizes.

When the cover is rotated, one or another of its openings corresponding to a certain size of seeds coincides with the holes on the disk, and the sowing apparatus is reequipped for sowing of seeds of a certain size fll

However, in a known seeding machine, an increase in the number of possible combinations of holes for seeding seeds is achieved by making different-sized holes on the patch along the arc length of a sector of its circumference, and a further increase in the number of possible combinations can occur only by increasing

The diameter of the sowing plate is larger, which leads to an increase in the weight and dimensions of the sowing apparatus. Expanding the range of sowing of seeds of various sizes is especially important for selective sowing.

In addition, the re-equipment of the known sowing apparatus for sowing seeds of one type or another is laborious.

The purpose of the invention is to expand the range of sizes of sown seeds for planting.

The goal is achieved by the fact that the sowing pad is formed by a series of small disks corresponding to the number of holes on the disk and meshing with each other, each small disk having evenly spaced large holes along its circumference. small disks in engagement are mirrored one relative to another. Ha FIG. 1 shows the proposed seeding apparatus in the embodiment of its pneumatic, section; in fig. 2 - the same, side view; in fig. 3 — Seeding pad assembly. The sowing machine consists of a family bunker 1 in which shaft 2 is placed with disk 3 mounted on it, with holes 4 evenly spaced around its circumference, small disks 6 are installed on the opposite side of the disk on axles 5, corresponding to the number of holes on the disk 3 and being in gearing with each other, with the small disks not extending beyond the diameter of the disk 3. On each small disk, differently sized holes 7, located in the increasing (or decreasing) follower, are uniformly along its circumference. awns largest diameter, and their location on the meshed small disk mirroring. The diameter of the largest hole of the small disk is equal to the diameter of the hole of the disk 3. In the embodiment of the proposed sowing apparatus — Pneumatic, on the side of small disks there is a vacuum chamber 8 connected to a vacuum source. A tedder 9 seeds is installed on the shaft 2. The device works as follows. Before sowing, the small disks 6 are turned so that one of the holes 7 on each small disk is aligned with the hole 4 on the sowing disk 3, and in this position the small disks 6 are fixed. Seeds in bunker 1 with agitator 9 when water is in motion. The vacuum chamber 8 through the openings 7 of the small disks 6 is connected with the corners 4 of the disk 3. The small disks b rotate together with the disk 3 in a fixed position. As a result, as the disk 3 rotates, the seeds located in the seeds 4 are sucked When the disc 3 leaves the zone of action of the vacuum, the seeds due to their own weight fall out of the holes. Chamfers made from the side of the seed bunker contribute to the best loss of seeds from the holes. 1 8 4 4 Re-equipment of the apparatus for sowing seeds of other sizes is carried out by turning the small disks 6 to align the corresponding hole 7 on each disk with hole 4 on the disk 3. If this hole is smaller than 4 holes on the disk 3, it is already sucked to the hole 7 on the small disk 6, but the seeding process remains the same. Seeds when the disk 3 leaves the vacuum zone fall out of the holes 4 of the disk 3. Thus, using the proposed sowing unit reduces the time spent on re-equipment of it when sowing various seeds without disassembling and assembling the device, which is especially important when breeding material. When the device is no crushing seeds n. An increase in the number of possible combinations of sowing holes for seeds is achieved by arranging different-sized holes along the circumference of the small disk. The length of the circle on which different-sized holes are located is longer than the arc length of the sector of the sowing plate in the known apparatus with the same dimensions. The invention The sowing machine, including a seed bin, a shaft with a disk with a series of holes evenly spaced around its circumference, and a pad with differently sized holes installed on the disk, characterized in that, in order to spread the size range of the sown seeds, the pad formed by a number of small disks corresponding to the number of holes on the disk and meshing with each other, each of the small disks having evenly spaced holes evenly spaced around its circumference, and the holes Finding ishhs in the engagement of small disks are mirrored one relative to another.
