Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, and in particular to a seed screening device for agricultural promotion. Background Technology
[0002] Agricultural extension is an activity that delivers advanced information technology and knowledge to farmers to help them adopt new ideas and skills. In agricultural extension, high technology is used to screen seeds and retain high-quality seeds in order to increase agricultural yield. For this purpose, a seed screening device for agricultural extension is needed.
[0003] Seed screening devices are equipment used to screen and classify seeds. Their function is to screen seeds according to their size, shape, and specific gravity, removing seeds that do not meet agricultural standards and retaining high-quality seeds, thereby improving agricultural yield and quality and developing the agricultural economy.
[0004] Seed screening devices on the market feed seeds manually, but this feeding method cannot control the feeding speed. If the feeding speed is too fast, the seeds will accumulate during feeding and need to be manually cleaned and unblocked. When discharging, the seeds are discharged directly through the funnel, and the seeds will also accumulate at the discharge port of the funnel due to friction, thus reducing work efficiency.

The fixing brackets 3 are used to fix funnels 4, and funnels 4 are fixedly connected between adjacent fixing brackets 3. Funnels 4 are used for discharging seeds. A fixing column 8 is fixedly connected to the top of the inner wall of the funnel 4, and a fixing rod 9 is rotatably connected to the middle of the fixing column 8. Stirring rods 7 are fixedly connected to the four sides of the outer wall of the fixing rod 9, and the stirring rods 7 are used to stir the seeds to prevent blockage at the outlet. A first bevel gear 6 is fixedly connected to the middle of the outer wall of the fixing rod 9. A second motor 5 is fixedly connected to the upper side of the outer wall of the funnel 4, and the output end of the second motor 5 passes through the funnel. 4 is fixedly connected to a second bevel gear 21, which meshes with the first bevel gear 6. Through this meshing connection, the second motor 5 can drive the fixed rod 9 to rotate. A hollow cone 10 is fixedly connected to the top of the outer wall of the fixed rod 9. The hollow cone 10 can evenly feed the seeds and prevent the seeds from entering the first bevel gear 6 and the second bevel gear 21. The top of the funnel 4 is connected to a hollow column 13. A first rotating disk 11 is fixedly connected to the bottom of the inner wall of the hollow column 13. The top of the fixed rod 9 passes through the first rotating disk 11 and is fixedly connected to a second rotating disk 12. The relative movement of the first rotating disk 11 and the second rotating disk 12 can control the feeding speed and prevent the feeding from being too fast and clogging the outlet. A flipping mechanism 2 is provided on the bottom side of the bottom plate 1. The flipping mechanism 2 is used to drive the seeds to be screened to flip so that they are screened more thoroughly.
[0033] Specifically, by starting the second motor 5, the second bevel gear 21 and the first bevel gear 6 connected to it are driven to mesh, thereby driving the fixed rod 9 to rotate. The fixed rod 9 drives the stirring rod 7 to rotate, which can stir the seeds accumulated at the bottom of the funnel 4 to prevent blockage. The hollow cone 10 can make the seeds that fall on it evenly spread around, while preventing the seeds from falling into the first bevel gear 6 and the second bevel gear 21. The fixed rod 9 will also drive the second rotating disk 12 to rotate. The feeding speed can be controlled by the relative movement of the first rotating disk 11 and the second rotating disk 12.

[0035] Specifically, the first motor 201 is started, which drives the first connecting rod 202 and the cam 203 connected to it to rotate around the first connecting rod 202. Then, the second connecting rod 204 drives the sealing cloth 206 and the screen 205 to turn over, so that the seeds can be screened more comprehensively when passing through the screen 205, and some inferior seeds are prevented from being retained due to blockage.
[0036] Reference Figure 1 , Figure 3 and Figure 5 The top of the hollow column 13 is provided with a flip cover 15, which can be closed when the device is not in operation to prevent dust from contaminating the interior. A hinge 14 is fixedly connected to the outside of the flip cover 15, and the flip cover 15 is rotatably connected to the hollow column 13 through the hinge 14. Multiple handles 19 are fixedly connected to the outside of the base 16 to make the device easier to move.

The blown air can blow the filtered seeds outward to prevent excessive accumulation and blockage. A controller 24 is fixedly connected to the top of the rear side of the outer wall of the base 16. The controller 24 is electrically connected to the second motor 5, the first motor 201 and the blower 25 respectively. The start and stop of the second motor 5, the first motor 201 and the blower 25 can be controlled by the button in the controller 24. U-shaped blocks 22 are rotatably connected to the four corners of the bottom of the base 16. The inside of the U-shaped blocks 22 is rotatably connected to pulleys 23, which make it easier to move the device when needed.
[0039] Specifically, starting the blower 25 can output air force, which is then dispersed through the vent 26. The air force blows the filtered seeds outward to prevent excessive accumulation. The controller 24 can control the starting and stopping of the second motor 5, the first motor 201 and the blower 25. The U-shaped block 22 and the pulley 23 make it easier to operate the device when it needs to be moved.
[0040] Working principle: Before using the device, the second motor 5 is started to drive the second bevel gear 21 and the first bevel gear 6 connected to it to mesh, thereby driving the fixed rod 9 to rotate. The fixed rod 9 drives the stirring rod 7 to stir, preventing excessive seeds from accumulating at the bottom of the funnel 4 and causing blockage. The hollow cone 10 can make the seeds that fall on it evenly spread around, while preventing the seeds from falling into the first bevel gear 6 and the second bevel gear 21. The fixed rod 9 will also drive the second rotating disk 12 to rotate. The feeding speed can be controlled by the relative movement of the first rotating disk 11 and the second rotating disk 12.
[0041] The first motor 201 is started, which drives the first connecting rod 202 and the cam 203 connected to it to rotate around the first connecting rod 202. Then the second connecting rod 204 drives the sealing cloth 206 and the screen 205 to turn over, so that the seeds can be screened more comprehensively when passing through the screen 205 by turning over, and some inferior seeds are prevented from being retained due to the screen 205 being blocked.
