Abstract

Seed drill for spreading fine grain seeds, characterized in that the gripping notches 9 are placed on the outer side edges of the buckets 8 before the direction of rotation and that the cover 7 is provided with undercuts which are located on the outer edges of the buckets 8 on the bucket wheel 4, the notches 9 being partially covered laterally and their ends extending in a flattened manner according to a slope 11 inclined tangentially to the periphery of the bucket wheel 4. The invention relates to a seed drill for spreading fine grain seeds.

Description

"Seeder for the application of seeds in fine grains" The invention relates to

a drill with

  a bucket seeder wheel which is equipped for

  the spreading of fine-grained seeds at the upper part of a lid surrounding the series or series of buckets and of which these buckets are provided with notches for receiving a single seed of seed and which is placed

  in rotation for a discharge at the top.

  When spreading seed grain

  such as rapeseed, it is a question of

  small quantities distributed in the same way

  more homogeneous possible. For this purpose, the speed of rotation

  necessary tapping of the wheel, bucket is so weak

  that in practice difficulties relating to the

  homogenous spread or the quantity spread is too large

  the fact that plants, especially in the case of rapeseed, are treated only slightly because of too great a density and therefore tend to

to be affected by the disease.

  According to DD 245 802, there is known a seed drill for fine grain seed in which there is a lid at the top on a bucket wheel provided for normal seed, whereby the series of buckets are surrounded so that between the buckets iv 1 9 6 6 9

  individual rooms are formed which during

  trays for top spreading receive several seed seeds from the reserve of

  seed in the sower box. Through a

  angled barrel from the outlet end of the lid occurs a progressive ejection from the chamber

  individual seeds. Thus, in fact, the

  are evenly distributed, the small number of

  seed is not exceeded.

  It has already been planned to provide the

  the buckets of a normal draft bucket wheel, so that when the seed is sown, fine grain seed is driven with the top outlet and only one seed is removed from the reserve of seeds. The surface of the buckets with the catching notch is inclined so strongly that the excess seeds in the seed bank are

  rejected. Despite the production of many

  Wet fill bucket occupations it is obtained

  overcrowding and plants are sensiti-

diseases.

  The object of the invention is to create a seed drill for fine grain seeds using a bucket wheel with which the seeds can be spread regularly in the small quantities desired. It is the invention to improve the drill with the bucket wheel so that in general it is extracted from each bucket and

  deposited only one seed of seed.

  This is achieved according to the invention in that the drawing notches are arranged on the outer lateral edges of the buckets forward with respect to the direction of rotation, and in that the lid is

  with remains on the outer edges of the

  cups on the bucket wheel, the

  samples partially overlap

  and exit at their end flattened

  with an inclination directed tangentially to the

  rim of the bucket wheel. The end of the skin protrudes inwards to the seed

  in the seed tank.

  Thanks to the invention, it is obtained that, by the double occupation of the scooping slots in the bucket of the seeding wheel, the superfluous seeds

  extracted by the cells and fall back from the

  seed tank in the sower box. The speed

  The rotation of the bucket wheel can, in addition, be chosen so small that the desired small number of seeds can also be provided in a distributed manner.

  The invention is now described more in

  detail with the help of an example of

  FIG. 1 is a section through a drill comprising a bucket wheel and a lid; - Figure 2, the cover seen from the front;

  - Figure 3, the side view of the latter.

  In the lower area of the container of

  seed 1 is seed drill 2. At seed drill 2

  3, the bucket wheel 4 which is placed on the shaft of the drill 5, a bottom hatch 6 as the lower closure of the housing and the lid 7. The latter surrounds the buckets 8 of the wheel to cups 4 in its upper part. In the direction of rotation on the front flank of the buckets 8 is machined the notch 9, so that it opens towards the outer face. The cover 7 is provided with scraps 10 which are located laterally on the outer surface of the cups 8, so that the catching notches cover about half the height. The end of the remains ends with

ramps 11.

  The ends of the ramps 11 on the

  They penetrate into the seed tank in the seed box. When the buckets, when

  rotation for the upper course, rotate through

  to the seed tank, the seizing slots take the seeds. The size of the notch is adapted to the size of the seed of the seed. If two seeds are in a notch 9, at least

  one of them protrudes from the edge. The

  det 8 moves in another rotation against the bodies 10, these gradually rising upwards with the ramp 11 to half-height

  of the notch 9. The surplus seed is thus ex-

  treats and falls back into the seed tank.
