Description

The seed drill, according to the present invention, is intended for uniformly distributed sowing of seeds with embedding them at a constant depth without redistributing soil particles vertically.

A distinctive feature of a knife-shaped coulter is that rotating blades, mounted on a force-rotated shaft, are used to distribute the seeds under the knife.

In FIG. 1 shows a longitudinal section through an exemplary form of the opener, in accordance with the invention; FIG. 2 is a top view, partly in section along the line AB, on the vomer of FIG. one.

Under the corner knife 4, for example, taken from the NIMIS flat cutter and fixed to the lower end of the tube 2, are bladed washers / mounted on a vertical shaft 3 passing through the tube 2. The upper end of the tube 2 is mounted, for example, on a frame of cultivator type machine for lifting it. At the upper end of the shaft S, bolt -5 is rigidly fastened to drive the rotation of the shaft 5 from the axis of the traveling wheels of one or another crop, not shown in the drawing.

The action of the opener according to the invention is that the seeds, the passage through tube 2 under knife 4, are evenly distributed along the bottom of the soil channel at a certain constant depth corresponding to the depth of the knife soil 4. Forced distribution of seed loops 1 eliminated em enveloping seeds with plant debris.

The subject matter of the invention.

A seed drill, made in the form of a knife mounted on a hollow tube, characterized in that rotating blades 1 mounted on the shaft 5 placed in the cavity of the tube 2 are used to distribute the seeds under the knife
