Description

The invention relates to the improvement of sowing machines for seedlings for sowing one grain at a time.

Seeds that have a seed box divided into separate sections with sowing machines for single-grain seedlings consist of: and from vertically mounted double rotating disks, between which there is an annular channel for seeds, are known.

Also known are discs in sowing devices equipped with hooks and pliers to engage with the ground.

These plants sowing machines have a complex structure and do not provide a clear sowing of one grain, moreover, they are narrowly specialized, as they are adapted to work with seeds of strictly defined sizes.

In the apparatus described, these disadvantages are eliminated by the fact that to distribute the seeds in one row to one grain, the annular channel between the discs is made tapering downwards by pressing the rotation.

FIG. 1 schematically shows a section of the cutter, side view; in fig. 2 and 3-irodol and transverse section of a separate sowing apparatus; FIG. 4-conditional transverse annular incision of the channel filled with grains.

Under the frame 1, the seeds are mounted on a ball leash 2 and a pole 3 with a spring, the body 4 of the sowing apparatus with the seed box 5 fixed above it, which communicates with the body channel 6.

A rotating disk 7 is mounted on the same axis with the housing 4, on the periphery of which the hooks 8 are located.

Between the housing 4 and the disk 7 is located connected with the second disk 9, made with the rim 10. The latter with an annular notch 11 of the disk 7 forms an annular channel 12.

The disk 9 in its lower part is clamped to the disk 7 by means of spring-loaded rollers 13, as a result of which the annular channel 12 is extended

No. 79571-2 in the upper part circumferentially n already in the lower part, where the wedge-shaped reflector is placed And with the separating spring 15. Under the outlet opening formed by the reflector 14 and the wall of the cornus 4, the seed wire 16 is located.

When the spindle moves by zero zero, the disk 7, zatyil about the night with night grades 8, freely rolls over it and rotates the disk 9 with itself in the direction indicated by the arrow and fig. 2

Seeds entering by gravity from the seed box 5, through channel 6, are filled with an annular channel 12 located in its upper part in several rows. As the disks 7 and 9 rotate, the seeds move downward and, due to the presence of the narrowed channel 12, are arranged in a row of one grain in its lower part (Fig. 4).

When the grains are in contact with the wedge-shaped reflector 14, the individual grains last are directed past the cutting spring 15 into the seed wire 16, which pushes the seeds 8 into the groove of the rotating disk 7.

Subject invention

An apparatus for sowing one grain, consisting of two vertically mounted discs with an annular channel between them, one of which is provided with soil allowances, characterized in that for distributing the seeds in one row, the annular channel between the disks is made tapering discs of one to the other through the spring rollers.
