Description

Technical Field

[0001] The invention relates to the technical field of seeding buckets for seed drills, in particular to a seeding bucket for seed drills. Background Art

[0002] There is a seed drill in the prior art, which is provided with a row of seed buckets, which include bucket boxes and seed-pulling shafts. The seed-pulling shafts are inserted into the bucket boxes and rotated. The rotating surface of the seed-pulling shafts has seed holes. Half of the upper part of the seed-pulling shafts is covered, and a brush is provided on the other half of the opposite side. The seed-pulling shafts and the brushes form a seed storage groove. The center of the seed-pulling shafts passes through a hexagonal shaft. The seed drill puts seeds into the seed storage grooves and controls the rotation of the seed-pulling shafts by rotating the hexagonal shafts. When the seed-pulling shafts rotate, the seed holes cover two or three seeds therein. After being squeezed by the brushes, the two or three seeds are pulled down to achieve the purpose of sowing. However, it is found in actual use that due to the friction on the surface of the seed-pulling shafts, some seeds that are in contact with the outer surface of the seed holes will be brought down when they rotate, resulting in more than two or three seeds sown at each location, resulting in a problem of seed waste. Summary of the invention

[0003] The object of the present invention is to provide a seed bucket for a seeder to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The present invention discloses a seeding bucket for a seed drill, comprising a bucket box and a seeding shaft, wherein the seeding shaft is inserted into the bucket box and rotated in cooperation, the center of the seeding shaft is a hexagonal tube hole, the rotating surface of the seeding shaft is provided with a seed hole, a fixed cover plate is provided at one end of the bucket box, the cover plate covers half of the upper part of the seeding shaft, a brush is provided at the other end of the bucket box, the elastic hairs of the brush can be closely attached to the rotating surface of the seeding shaft and extend downward, the seeding shaft and the brush form a seed storage groove, and the characteristics are as follows;

[0006] It also includes an arc-shaped metal skin, which covers the other half of the upper part of the seed-moving shaft and slides with the seed-moving shaft. The upper end of the arc-shaped metal skin is fixedly connected to the cover plate, and the lower end is close to the brush. A U-shaped notch is provided in the middle of the arc-shaped metal skin. The U-shaped notch is the same width as the seed hole, and the seed hole moves in the U-shaped notch.

[0007] As an improvement, a hand-turned head is provided at the outer end of the seed-selecting shaft.

[0008] As an improvement, the seed-selecting shaft is slidably matched with the cover plate.

[0009] As an improvement, a seed placement pipe is provided at the lower end of the bucket box.

[0010] As an improvement, mounting holes are provided at the four corners of the top surface of the bucket box.

[0011] Compared with the prior art, the advantages of the present invention are as follows: a row of bucket boxes are installed at the front end of the seed drill through the installation hole, the seed tube faces downward, and the hexagonal rotating shaft is inserted into the hexagonal tube hole. When sowing, the hexagonal rotating shaft rotates while the seed drill moves forward, and the seeds of the seed drill naturally fall into the seed storage groove. The hexagonal rotating shaft drives the seed-pickup shaft to rotate toward the brush. When the seed hole enters the U-shaped notch, two or three seeds will fall into the seed hole immediately. As shown in the figure, as the seed-pickup shaft rotates to the right, the seed hole covers the two or three seeds and is squeezed by the brush. Only these two or three seeds are pulled down and then fall from the seed tube to the ground. The remaining seeds that fall on the seed-pickup shaft or the surface of the curved metal skin are squeezed and blocked by the brush and cannot be pulled down. For each rotation of the seed-pickup shaft, only two or three seeds in the seed hole can be smoothly pulled down and fall to the ground.

[0012] This is used for the seed bucket of the seeder. The arc-surface metal skin covers the other half of the seed-push shaft. The seed hole can only run in the U-shaped notch. The rest of the seeds that fall on the seed-push shaft or the surface of the arc-surface metal skin have a very short friction stroke or no friction, and are easily squeezed and blocked by the brush and cannot be pushed down, avoiding sowing excess seeds and causing waste.
