Description

Technical Field

[0001] The invention relates to the technical field of seed screening, and in particular to a vegetable seed screening device for vegetable planting. Background Art

[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms, formed by ovules through pollination and fertilization. The formation of seeds allows the young sporophyte ovules to be protected by the mother and to receive sufficient nutrients like the fetus of a mammal. Seeds also have various structures suitable for dissemination or resistance to adverse conditions, creating good conditions for the continuation of the plant race.

[0003] During the harvesting and storage process, vegetable seeds often contain more impurities due to the influence of external processing factors. The impurities include fine powder impurities such as fine sand and soil, as well as large impurities such as straw and corn cobs. Therefore, screening devices are often used for screening to ensure the germination rate and seed vitality when the seeds are planted.

[0004] When screening, the seed screening device in the prior art usually uses a vibrating screen to screen a single type of seeds, and the scope of application is relatively low. At the same time, when the seed size is similar to the mesh size of the screen, the seed will be stuck in the mesh, which will cause the screen to be blocked and reduce the overall screening efficiency. In the prior art, the screen is mostly manually removed for cleaning, and the cleaned screen is installed on the equipment for screening. The process requires a lot of labor and the equipment needs to be suspended, affecting the overall screening efficiency.

[0034] The screening assembly comprises a plurality of screening frames 3 and a plurality of screening elements. The two ends of the screening frames 3 are respectively hinged with support frames 4, one of which is slidably connected to the screening box 1, and the plurality of screening elements are respectively arranged in the screening box 1, and the other support frame 4 is drivingly connected to the screening element. A screening net 5 is detachably connected in the screening frame 3;

[0035] A cleaning assembly, comprising a plurality of cleaning pieces, each of which is disposed on a plurality of screening frames 3 and is located below the screening net 5, and the cleaning pieces are used to clean the meshes of the screening net 5;

[0036] A number of collecting components are respectively arranged at one end of a number of screening frames 3. The number of screening frames 3 are distributed along the axial direction. The collecting components are used to collect seeds and convey the seeds to the adjacent lower screening mesh 5.

[0037] In an embodiment of the present invention, during use, the seeds are conveyed to the uppermost screening mesh 5 through the feed inlet 2. The screening mesh 5 is driven by the provided screening components to screen the seeds. The screened seeds are respectively conveyed into the collecting components, realizing hierarchical storage and conveying to the lower screening mesh 5. During the screening process, seeds with sizes similar to the mesh holes of the screening mesh 5 are easily stuck in the mesh holes. The provided cleaning component extends into the mesh holes to eject the seeds blocked in the mesh holes, thereby realizing the cleaning of the mesh holes and ensuring the stable screening of the screening mesh 5.

[0038] As an alternative embodiment, the screening component includes a support plate 6. The support plate 6 is fixedly connected to the inner wall of the screening box body 1. A vertical rod 7 is slidably connected to the support plate 6. A cross rod 8 is fixedly connected to the support frame 4. One of the cross rods 8 passes through the vertical rod 7 and is fixedly connected with a first limit block 9. The other cross rod 8 is fixedly connected to the inner wall of the screening box body 1. A driving motor 10 is fixedly connected to the support plate 6. A cam 12 is fixedly connected to the output shaft of the driving motor 10 through a rotating shaft 11. The top end of the vertical rod 7 is fixedly connected with a second limit block 13. The cam 12 is in contact with the second limit block 13.

[0039] In an embodiment of the present invention, the driving motor 10 is provided to drive the cam 12 to rotate. When the cam 12 rotates, it drives the vertical rod 7 to move downward. When the vertical rod 7 moves downward, it drives the screening mesh 5 to move, and then repeatedly moves to cooperate with the screening mesh 5 to realize vibration screening, improving the screening efficiency.

[0040] As an alternative embodiment, a first spring 31 is sleeved on the vertical rod 7. Both ends of the first spring 31 are respectively fixedly connected to the bottom end of the second limit block 13 and the top end of the support plate 6.

When the moving roller 23 rises, it drives the flexible belt 15 to rise and makes the corresponding cleaning head 16 extend into the mesh holes to clean the blocked seeds in the mesh holes. The cleaning of the screening mesh 5 is realized by the movement of the moving blocks 18 from the high point to the low point, and at the same time, the flexible belt 15 moves in a wavy shape to convey the seeds on the flexible belt 15 into the collecting member, avoiding seed accumulation.

[0048] Specifically, the flexible belt 15 is made of an elastic material. After the moving roller 23 separates from the flexible belt 15, the flexible belt 15 returns to a flat state.

[0054] In one embodiment of the present invention, the top end of the cleaning head 16 is a rubber head 28. At the same time, a groove 29 is formed at the top end and the outer edge is an arc structure, thereby avoiding damage to the seeds caused by extrusion when the cleaning head 16 cleans the seeds blocked in the mesh holes.

[0055] As an alternative embodiment, a plug-in slot 30 is formed on one side of the screening frame 3. The screening mesh 5 is inserted into the screening frame 3 through the plug-in slot 30.

[0056] In one embodiment of the present invention, the convenient installation and replacement of the screening mesh 5 are realized through the provided plug-in slot 30, which is adapted to the screening of seeds of different sizes.
