DE3311994A1 - Seed-spacing drill - Google Patents

Abstract

In a seed-spacing drill, a rotating cellular wheel (3) is provided in a hollow-cylindrical housing (1). This cellular wheel (3) has cells (9), which the seed grains to be sown enter and out of which they fall in the region of a seed outlet (7). The cells (9) are covered at the top by a cover (6). A stripper (12) in the form of a brush is arranged in front of the entry edge (10) of the cover (6). This stripper prevents seed from striking the entry edge of the cover (6). If the cells (9) are doubly occupied, it brushes a seed grain out of the respective cell (9). <IMAGE>

In order to achieve as regular a game as possible in the testicle, it is necessary that the cellular wheel at least approximately a peripheral speed; that corresponds to the forward speed of the precision air seeder. The seeds then hit \\.

Seed breakage occurs through which the affected hair grains lose their ability to germinate.

In order to keep the seed breakage small, it is known that the Leading edge of the cover with a nr Absnhrnqunq / u Mistake. This is the case, for example, with the precision seeder according to the aforementioned DE-DS 29U0247 ripr. This measure allows the number of "hard, Reduce the grains beating against the leading edge still to semen breakage, as the ones stretching out of the cells The seeds inevitably hit the leading edge of the cover, which is designed as a cutting edge, before they fall back down within the cellular wheel .

The invention is based on the object of a Lln / p.i-. to train the seeder so that even at high Circumferential speeds of the cell wheel the proportion van damaged seed is as low as possible.

In the case of double occupancy, the protruding seed is able to pass the scraper, since it is able to move inward, but is given a twist that rolls it out of the cell after passing the scraper, ππ rJr-ιΠ it can then fall down . Thanks to the Γrfindung so Uird avoided that seeds ι to di beat ^one leading edge of the cover and thereby · lu - ujerden damaged.

An adaptation to different seeds is possible if according to an advantageous embodiment of the invention the scraper is designed to be adjustable at a distance from the inner circumferential surface of the cell wheel.

The ability of Ausuei chenrj is particularly easy to reach inside at the scraper, uiRnn he consists of elastic material.

It is advantageous if the scraper πίπ brush is trained, uieil he is then particularly reliable in, the respective seeds from double-occupied cells can roll out. You can leave this UJirkungr refer to as sweeping out or brushing out.

A particularly simple way of evading the scraper is to do this by spring force or a weight in a fixed Distance to the inner surface of the filler wheel to keep.

Seed can enter the housing 1 through a seed inlet 8 in the end face of the housing 1. The individual seeds then move along the inner circumferential surface 5 of the filling wheel 3 and are able to move into individual ones. Cells H to get into the outer surface of the bucket wheel 3. These cells 3 are produced by inclined bores.

The cover 6 has an inlet edge 1ΓΙ, uelr.hR through a bevel 11 is formed in the shape of a cutting edge.

- The functioning of the precision seeder according to the invention is as follows:

By rotating the bucket wheel 3 it is achieved that the seeds entering through the seed inlet θ open the inner circumferential surface 5 with in the direction of the inlet edge 10 led uiird. Most of it happens Reaching the scraper 12 back down into the cellular wheel 3. The seeds get into the area of the lower left quadrant seeds in the cells 9. Are divided into individual cells to form seeds reaches, zuiar can also do that inwards from the Cell protruding seed grain to pass the bristles 13 of the stripper 12, but uird from these bristles 13 set in rotation so that it is above the scraper 12 before the inlet edge from the cell comes out and falls back down in the cellular wheel. There is no impact against the inlet edge 10 and thus no seed breakage. Important for this function is that the scraper 12 spacing from the inlet edge 10, so that the seeds passing through the scraper 12 are above the scraper can fall back.
