Description

Technical Field

[0001] This utility model relates to the field of seed dust removal technology, specifically a dust removal device for seed processing. Background Technology

[0002] Seed processing typically refers to the steps taken during seed production to protect seeds using biological, physical, and chemical agents and technologies, thereby improving seed planting and production efficiency. To reduce the impact of dust, seeds are usually dusted to reduce the risk of spoilage and pests during storage and ensure the stability of long-term seed preservation.

[0003] After drying, seeds will be covered with a lot of dust. In the current technology, seed dust removal only uses a single vibrating screen or wind separation, which easily leads to low dust removal efficiency. After screening, dust (such as seed coat debris, microbial spores, etc.) is still easily attached to the seed surface. The large amount of dust on the seed surface makes it easy to absorb moisture from the air, which can lead to bacterial growth and necrosis when the seeds are collected and stored. Utility Model Content

During operation, the multiple exhaust fans 24 extract the fine dust scattered inside the housing 1, thereby completing the dust removal work.

[0022] Multiple fixing rods 6 are fixedly connected between the two mounting plates 4 and the rotating plate 2. A rotating shaft 7 is rotatably installed between the top corners of the two mounting plates 4. The rotating shaft 7 passes through the rotating plate 2 and is rotatably connected to the rotating plate 2.

[0023] A first motor 8 is fixedly connected to the top of the rotating plate 2. A first bevel gear 9 is fixedly connected to the output end of the first motor 8. A second bevel gear 10 is meshed with the bottom of the first bevel gear 9. The second bevel gear 10 is sleeved on the outside of the rotating shaft 7 and fixedly connected to the rotating shaft 7. A first gear 11 is fixedly connected to the outside of both ends of the rotating shaft 7. A first toothed ring 12 is fixedly connected to the outside of both ends of the filter cylinder 3. The two first gears 11 are meshed with the two first toothed rings 12 respectively. When working, the rotating shaft 7 drives the filter cylinder 3 to rotate, causing the seeds to tumble and rub, throwing off the dust on the surface of the seeds, making the dust on the seeds cleaner.

[0024] A third gear 14 is rotatably mounted on one side of the mounting plate 4 at the front end of the filter cylinder 3. A second gear ring 15 is fixedly connected to the front end of the feeding auger 5. The third gear 14 and the second gear ring 15 are meshed together. A second gear 13 is fixedly connected to the front end of the rotating shaft 7. The second gear 13 and the third gear 14 are meshed together. A baffle 26 is provided at the bottom of the mounting plate 4 at the front end of the filter cylinder 3. The bottom of the baffle 26 is fixedly connected to the housing 1. When working, the rotating shaft 7 drives the feeding auger 5 to rotate in the opposite direction. The seeds are stirred and move forward while rubbing against each other, so that they are discharged from the collection hopper. The baffle 26 prevents the thrown seeds from hitting the front wall of the housing 1 and bouncing to the bottom of the filter cylinder 3.

[0025] Two mounting plates 4 are fixedly mounted with springs 16 on both sides of the bottom. The bottom ends of the four springs 16 are fixedly mounted inside the bottom of the housing 1. A U-shaped plate 17 is fixedly connected to the bottom of the housing 1. A cam 18 is rotatably mounted inside the U-shaped plate 17. A second motor 19 is fixedly connected to the rear side of the housing 1. The output end of the second motor 19 is fixedly connected to the cam 18. During operation, the mounting plates 4 are always in contact with the cam 18 under the action of the springs 16.

[0026] A baffle plate 20 is rotatably connected to the inner rear end of the feeding auger 5. A limit plate 21 is fixedly connected to the bottom rear side of the baffle plate 20. Two limit rods 22 are fixedly connected to the inner rear wall of the housing 1. The limit plate 21 is located between the two limit rods 22 and slides in contact with the two limit rods 22. The baffle plate 20 prevents the seeds from falling out from the rear end of the filter cartridge 3 when they enter the filter cartridge 3.

[0027] A feeding funnel 23 is fixedly connected to the rear side of the box 1. The bottom outlet of the feeding funnel 23 is fixedly connected to the limiting rod 22 through a corrugated pipe. A collection hopper is fixedly connected to the front bottom of the box 1. A box door 25 is hinged to one side of the box 1. When some dust that was not sucked up by the exhaust fan 24 falls into the bottom of the box 1 after work, the box door 25 can be opened to clean it.

[0028] In use, the seeds are fed into the housing 1 through the feeding funnel 23. When the dust removal is working, the second motor 19 is started. The second motor 19 drives the cam 18 to rotate. The rotating plate 2 rotates and is located in the middle of the filter cylinder 3 and is rotatably connected to the housing 1. A spring 16 is fixedly connected between the bottom of the mounting plate 4 and the housing 1. The mounting plate 4 at the rear end of the housing 1 is always in contact with the cam 18 under the action of the spring force of the spring 16. The rotation of the cam 18 drives the mounting plate 4 to move up and down, so that the filter cylinder 3 swings back and forth about the rotation connection between the rotating plate 2 and the housing 1. The vibration shakes off the dust on the seed surface. At the same time, the first motor 8 starts working. The first motor 8 drives the rotating shaft 7 to rotate through the first bevel gear 9 and the second bevel gear 10. The rotation of the rotating shaft 7 drives the first gear ring 12 to rotate through the first gear 11. The first gear ring 12 is fixedly connected to the filter cylinder 3. At this time, the rotation of the filter cylinder 3 causes the seeds to tumble and rub against each other inside the filter cylinder 3, thereby cleaning the dust on the seed surface. The fine dust floats inside the box 1. The exhaust fan 24 at the top of the box 1 works to draw out the dust floating inside the box 1, thus completing the dust removal work for the seeds. At the same time, the rotation of the rotating shaft 7 drives the second gear 13 at the front end of the rotating shaft 7 to rotate. The second gear 13 drives the second gear ring 15 to rotate through the third gear 14. The second gear ring 15 drives the feeding auger 5 inside the filter cylinder 3 to rotate in the opposite direction. The auger blades of the feeding auger 5 are in contact with the inner wall of the filter cylinder 3. When the feeding auger 5 rotates, the seeds at the rear end of the filter cylinder 3 move forward under the action of the auger blades and are discharged from the collection hopper at the front end of the box 1.

[0029] The baffle plate 20 is rotatably connected to the feeding auger 5. The limiting plate 21, which is fixedly connected to the rear side of the baffle plate 20, slides between the two limiting rods 22. The limiting rods 22 limit the limiting plate 21, so that the baffle plate 20 will not rotate while vibrating up and down with the mounting plate 4. This allows the feeding funnel 23 to continuously feed the seeds into the filter cartridge 3 for dust removal through the corrugated pipe.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
