Seeder for precise placement of single grains

So, too, are the small grain planters that have become known so far Precision grooves called ~ throw the individual grains from a cellular wheel over the seed furrow one - horizontal that deviates from the driving speed Speed down, so that - especially at higher driving speeds - rolling the grain enters the furrow when it hits »whereby their position becomes imprecise and sometimes deviates considerably from the planned intervals.

The principle of the method according to the main patent *. * * (Patent Application K 52 838 IXI / 45 b) now consists in the grains alone au seen by a lan ^ saalaufendeβ cellular au "the stock and in a provided with chambers second lad einaeln in to bring the laanaers t with hazy laying wheel - ttabove the driving speed corresponding to the driving speed rolls over dtr Säfuroht, so that the grains from the individual chambers without - or

can be put down almost without horizontal speed to the ground and therefore also at high driving speed do not roll in the seed furrow.

A seed drill that works precisely must have it in addition, further conditions are met »·

a) Avoidance of double fillings or lack of fillings in the cells, even with mixtures of fiaohen and spherical seeds »

b) The degree of unevenness should be as independent as possible from the Be the driving speed, therefore the longest possible filling distance of the cellular wheel.

c) Avoidance of semen damage.

d) Deep position of the deposit opening above the sowing furrow in order to report a higher vertical fall speed.

In addition - for the purpose of adapting to practical requirements -

e) wide choice of seed spacing, e.g. B. 4, 5, 6, 8, to, 12, 15, 2o and 3o da,

f) Convenient interchangeability of the cellular wheel and / or the secondary wheel, for use in beans, corn, beet seeds, Grain and noise.

g) Small overall width for grain or Geaüe * eaat.

The iärftilluag this Krfqrdernieee is together not by individual measures for themselves but only through their suitable combination in an overall construction accessible.

In accordance with the invention ds by the one described below Device achievable as an advance over the known types.

Under the seed hopper 1 as shown in Figure A is a disc rotating about a vertical axis 2 3 arranged with a cellular ring 4, as a result lan ^ e J? üllstrecken der Bellen after requirement b achieved will and - as research has shown to practice a Such an arrangement in the degree of filling is not very sensitive to larger changes in speed. The depth of the cells can be chosen to be relatively small in relation to the diameter » because their position to gravity remains the same and is insensitive to sole oar forces, so that they are suitable for a mixture of spherical and flat seeds, without significant numbers of To effect double fillings. If the opening 5 of the seed storage container - as provided according to the invention If - shortly above the cell disc, smaller than the diameter of the cell ring, so is an inexpedient pressure on the above the

Prevents cells from located and moving grains * On the one hand, this ensures a certain mobility between the grains, which prevents them from falling individual grains in the cells, ▼ on the other hand, prevents coarse grains that by the grains deposited over the filled cells, ready filled cells are torn empty again " This arrangement fulfills funding a and b.

The cell disc 3 is seen with a grain removal device ▼, which the individual grains laterally, d. H. in radial direction, drains from the cells, as shown in picture C. The cell disk 3 is coupled to the also rotating base 11, driven by the shaft 2. liie cell seal 3 is provided with punched, milled, cast or pressed cells 12 and made of metal, plastic or Rubber made. In front of the discharge point in the transfer wheel, a displacer 13 is arranged above the Cell wreath removes the grains. A cover 13 prevents grains from slipping back again from stock. The base rotating with the cell disc is provided with a recess 14, into which a scraper 15 engages, while a similarly shaped second one above the cell ring Wiper is arranged.

A similar arrangement is shown in Figure D, each

but with a special rotating displacer that is driven by the base 11.

In addition to the discharge parts, the outer ring of a vertical disc 6 passing This Hing of the Ablegeradee is formed from chambers 3, which are open to the side of the cell disc, and in the approximately at the apex of the deposit a the grains from the cells with passing Ka "~ mern are introduced on the cells through the grain discharge device.

Haoh the transition point of the individual grains of the ^ eIIe to the chamber becomes the side and the am Circumferential opening of the Kämmerrin ^ es of the disc by the fixed Abdsokung 7 to about the lower sparks of the disc held closed, after the end of this point in each case Exceeding grain falls out of the chamber in the furrow formed by the coulter 9 just below. This fulfills requirement d.

Bas the offshoot gear 6 is through a bevel gear set 1oa and 1ob with the iJellenaoheibe speed-wise coupled in such a way that the peripheral speed of the Ablegeradee it is in the same ratio as the distance to the circumferential speed of the cellular wheel ring the opening of the chambers of the disc wheel to the distance

the cells of the cell wheel ,. UIe circumferential speeds are according to the invention in a ratio of 5J1, so if the 2-pin crane length is dimensioned to two fifths of the sprocket, the bevel gear has a gear ratio of 1J2 .

If, for example, 5 cm is selected as the fixed smallest separation distance between the grains, the distance between the cells is 1 era if each chamber is to be filled with one grain. If only every second chamber is filled, the depositing distance is 1o cm, every third 15 om, every fourth 20 cm, every sixth 3ο om. This means that the cellular wheel must contain at least 12 cells or a multiple of this number. Usable dimensions for the row disk and laying wheel result for Ftinsämereicn with 24 cells, with coarser seeds with 48 cells. The circumference of the cell disc and the turning wheel are then 48o mm and 5/2 χ 48'12oo mn old diameters of about 153 mm and 383 ma.

The exact placement on 5, 1o, 15, 2o and 3o om occurs naturally only if the peripheral speed of the placement wheel is exactly the same as the driving speed is equivalent to. Zwlsohenmafle can be according to the invention achieve when the disc wheel with slightly lcleint-
