Abstract

The invention relates to the field of agricultural engineering and can be used in the fields of precise sowing of seeds of various crops. The purpose of the invention is to reduce the metal structure with a precise seeding of seeds in several rows. The apparatus includes a housing 2 in which the drum 3 is located with paired scoops 4 located above the inclined symmetrically diverging channels 5. In the areas of seed rolling along the channels 5 there are funnels. A part of the channels 5 is in radially diverging planes, and a part in planes located at an angle to the radial planes in the direction of rotation of the drum and against it. The seeds are picked up by the scoops 4 and in the upper part of the drum 3 are rolled down the channels 5 into the funnels. As a result of different angles of inclination of the channels to the radius of the drum, the seeds roll into the funnels over time. 2 hp f-ly, 6 ill.

The purpose of the invention is to reduce the metal content of the structure while accurately introducing seeds into several rows.

FIG. one; in fig. 3 - the scheme of sowing Yu with an angle. a drum with an indication of the angles of displacement of the axes of the channels relative to the radius of rotation of the drums (section of the lower part, side view); in fig. 4 is a schematic of the arrangement of the scoops with an inclined semiconductor channel displaced against the rotation of the drum in all three zones, indicating the discharge of the seeds in the zone of the first funnel; in fig. 5 - the same, with an inclined sem conducting channel in radially diverging planes; in fig. 6 - the same, with the slope of the semiconductor channels in the direction of rotation of the drums.

The metering device contains a seed bunker 1 installed above the housing 2, inside of which the seed drum 3 rotates, in the center of the circuit, which are arranged twin intakes in the form of calibrated scoops 4 located above the inclined symmetrically diverging conductive channels 5 (Fig. 1).

6 of the scoops roll down the inclined channels 5 and through the opener are distributed with a given frequency in a row.

As a result of the different angle of inclination of the projection of the axes of the semiconductor channels 5 to the radius of the drum 3, the seeds roll into the funnel 7 extended in time, as a result of which from the channels 5 the seeds fall into the funnel 7 first from the channel with the angle of inclination (- a, then -a, and at the end of the channel

From scoops 4, the most likely rolling of seeds 6 from this seven conductive channel 5 s occurs when it is in a vertical (or close to vertical) position in the rolling zone of the seed AO (Fig. 5), and from the scoops 4 with an angle the slope of the rotation of the drum 3 (seed channel 5 s + a), respectively, the most likely decline of seeds from the seven conducting channels 5 to zone A + will also be 20 in the vicinity of the perpendicular position of the channels 5 in this zone (Fig. 6) .

The considered design of the sowing unit can be made of two sowing drums 3, synchronously rotating with a chain transmission. The number of simultaneously sown rows for such a device is twelve (three rows from each end of two drums).
