Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed drop hopper for seeding machine, specifically point to a kind of seed drop hopper for seeding machine. BACKGROUND

[0002] There is a kind of seeding machine in prior art, which is provided with a row of seed drop hoppers. The seed drop hopper includes a hopper box and a seed pushing shaft. The seed pushing shaft is inserted into the hopper box and rotates. The rotating surface of the seed pushing shaft is provided with a seed hole. The upper half of the seed pushing shaft is covered by a cover. The other half of the seed pushing shaft is provided with a brush which is tightly attached to the seed pushing shaft. The seed pushing shaft and the brush form a seed storage groove. A hexagonal shaft is arranged at the center of the seed pushing shaft. The seeding machine throws seeds into the seed storage groove. At the same time, the rotation of the seed pushing shaft is controlled by rotating the hexagonal shaft. When the seed pushing shaft rotates, the seed hole covers two or three seeds in it. The two or three seeds are pushed down by the brush, thereby achieving the purpose of seeding. However, it is found in actual use that due to the friction of the surface of the seed pushing shaft, some seeds which are in contact with the surface of the seed hole will also be taken down along with the seed pushing shaft when the seed pushing shaft rotates, resulting in that the number of seeds planted at each location exceeds two or three, and the problem of seed waste exists.

[0026] The present embodiment is combined with the drawings Figures 1 to 5 A seed sowing hopper for a seeding machine is described in detail.

[0027] This embodiment provides a seed hopper for a seeder, comprising a hopper box 1 and a seed-dispensing shaft 2. The seed-dispensing shaft 2 is inserted into the hopper box 1 and rotates within it. The center of the seed-dispensing shaft 2 is a hexagonal tube hole 3, and the rotating surface of the seed-dispensing shaft 2 is provided with a seed hole 4. One end of the hopper box 1 is provided with a fixed cover plate 5, which covers half of the upper part of the seed-dispensing shaft 2. The other end of the hopper box 1 is provided with a brush 6, the elastic bristles of which can adhere to the rotating surface of the seed-dispensing shaft 2 and extend downward. The seed-dispensing shaft 2 and the brush 6 form a seed storage groove 7.

[0028] It also includes an arc-shaped metal sheet 8, which covers the other half of the upper part of the seed-dispensing shaft 2 and slides with the seed-dispensing shaft 2. The upper end of the arc-shaped metal sheet 8 is fixedly connected to the cover plate 5, and the lower end is close to the brush 6. A U-shaped notch 9 is provided in the middle of the arc-shaped metal sheet 8. The U-shaped notch 9 has the same width as the seed hole 4, and the seed hole 4 moves within the U-shaped notch 9.

[0029] The outer end of the seed-dispensing shaft 2 is provided with a hand-operated head 10.

[0030] The seed-dispensing shaft 2 is slidably fitted with the cover plate 5.

[0031] The lower end of the hopper box 1 is provided with a seeding tube 11.

[0032] The top surface of the bucket box 1 has mounting holes 12 at the four corners.

[0033] In practical implementation, a row of several seed hoppers 1 are installed at the front end of the seeder through the mounting holes 12, with the seed tube 11 facing downwards. A hexagonal rotating shaft passes through the hexagonal tube hole 3. During sowing, as the seeder moves forward, the hexagonal rotating shaft rotates, and the seeds naturally fall into the seed storage trough 7. The hexagonal rotating shaft drives the seed-feeding shaft 2 to rotate towards the brush 6. When the seed hole 4 enters the U-shaped notch 9, two or three seeds will immediately fall into the seed hole 4. Figure 3 As shown, as the seed-dispensing shaft 2 rotates to the right, the two or three seeds covered by the seed hole 4 are squeezed by the brush 6, and only these two or three seeds are dispensed and fall into the ground from the seed tube 11. The remaining seeds that fall on the seed-dispensing shaft 2 or the surface of the curved metal sheet 8 are blocked by the brush 6 and cannot be dispensed. Each time the seed-dispensing shaft 2 rotates, only two or three seeds in the seed hole 4 can be successfully dispensed and fall into the ground.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
