(54) PLANTING DEVICE

one

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

The sowing devices are known, including a bunker, a sowing disc 1C located therein in cells and a rotary sem wire.

However, such devices have low metering accuracy, and the presence of reflective ejector devices and a valve system in the channels leads to a significant uneven distribution of the seeds in the furrow and to their damage.

In order to eliminate the above drawbacks in the proposed seeding apparatus, the seeding disc is made with through-grooves, and the cells for the seeds are formed by the grooves of the disc and the wall of the hopper.

On .fig. 1 schematically shows the proposed sowing apparatus, a general view and a section along A - A; in fig. 2 - a cell with a seed.

The device contains: a housing 1, a hopper 2, a sowing disk 3, a rotary sem wire 4, an adjustable damper 5, a ring 6 and an outflow port 7. The sowing disc 3 and a rotary sem wire 4 mounted on one

the axes are rigidly connected and the walls of the bunker 2 separate them (see Fig. 2).

Seeds in the loading area of the hopper 2 fall into the cells formed by the through grooves of the sowing disk 3 and the wall of the hopper 2. When the sowing disk of the sowing disk with the seeds rotates, it leaves the total seed mass, released from the seed, and when the discharge window reaches 7 the wall of the hopper 2 unloads the cells into the channels of the rotary seed wire 4. Next, the seeds are moved through the channels of the rotary seed wire and are thrown into the soil through a window in the lower part of the housing 1. The level of the seeds in the loading zone is maintained using p Adjustable damper 5.

Subject invention

A sowing unit including a hopper, a sowing disc with seed cells and a rotary sem wire in it, characterized in that, in order to increase the uniformity of seed distribution in the furrow and reduce their damage, the sowing disc is made with through slots, and Seed N formed by the grooves of the disk and the wall of the hopper.
