[0023] Example

[0024] Reference Figure 1-4 This is an embodiment of the present invention, which provides a seed screening device, comprising:

[0025] The system includes a fixed frame 101, a pedal 102 fixedly mounted at the end of the fixed frame 101, a mounting bracket 103 fixedly connected to the side wall of the fixed frame 101, a vibration assembly 104 fixedly mounted at the end of the mounting bracket 103, and an operating assembly 105 used in conjunction with the vibration assembly 104.

[0026] The vibration assembly 104 includes a fixed plate 104a, a limiting post 104b inserted into the surface of the fixed plate 104a, a vibration spring 104c sleeved on the side surface of the limiting post 104b, a connecting plate 104d fixedly connected to the end of the vibration spring 104c, and a clamping component 104e disposed in the inner cavity of the fixed plate 104a, wherein the clamping component 104e clamps the limiting post 104b in the center.

[0027] The clamping component 104e includes a sheet body 104e-1, a plug-in plate 104e-2 fixedly connected to the inner cavity of the sheet body 104e-1, and a pressing rod 104e-3 plugged into the side wall of the plug-in plate 104e-2.

[0028] The clamping component 104e also includes a return spring 104e-4 sleeved on the outer surface of the extrusion rod 104e-3, a clamping plate 104e-5 fixedly connected to the end of the extrusion rod 104e-3, and an insertion groove 104e-6 opened in the cavity of the sheet body 104e-1.

[0029] Specifically, the operator steps on pedal 102 to provide initial power. The limiting post 104b in the vibration assembly 104 is stably supported within the fixing plate 104a of the clamping component 104e. After the vibration spring 104c is stressed, it drives the connecting plate 104d to generate reciprocating vibration. The clamping component 104e, through the cooperation of the squeezing rod 104e-3 and the return spring 104e-4, makes the clamping plate 104e-5 elastically clamp the limiting post 104b to ensure that it does not loosen during vibration. The vibration energy is transmitted to the operating component 105, which drives the sieve plate 105d to vibrate efficiently, so that the seeds are evenly distributed on the sieve and the screening is completed. Qualified seeds are discharged through the feeding plate 105e, and unqualified materials are separated.

[0030] The operating assembly 105 includes an operating box 105a, a support column 105b fixedly connected to the inner cavity of the operating box 105a, a snap-fit ​​component 105c snapped onto the outer surface of the support column 105b, a screen plate 105d fixedly connected to the side surface of the snap-fit ​​component 105c, and a feed plate 105e fixedly installed on the side wall of the operating box 105a.

[0031] The snap-fit ​​component 105c includes a connecting block 105c-1, a slot 105c-2 formed on the side surface of the connecting block 105c-1, and a plug-in sleeve 105c-3 fixedly connected to the side wall of the connecting block 105c-1.

[0032] The snap-fit ​​component 105c also includes a telescopic rod 105c-4 inserted into the center of the plug-in cylinder 105c-3, a compression spring 105c-5 sleeved on the outer surface of the telescopic rod 105c-4, and a snap-fit ​​block 105c-6 fixedly connected to the end of the telescopic rod 105c-4.

[0033] It should be noted that after the operator steps on pedal 102 to start the device, the vibration component 104 drives the connecting plate 104d to generate stable vibration through the limiting column 104b and the vibration spring 104c. This vibration is transmitted to the screen plate 105d through the snap-fit ​​component 105c. In the snap-fit ​​component 105c, the telescopic rod 105c-4 pushes the snap-fit ​​block 105c-6 to engage tightly with the support column 105b under the action of the compression spring 105c-5, ensuring that the screen plate 105d is firmly connected and does not shift when vibrating. The seeds are evenly dispersed on the vibrating screen plate 105d and the grading and screening are completed. Qualified seeds fall through the screen holes and are discharged by the discharge plate 105e. Unqualified materials remain above the screen plate 105d.

[0034] In use, mechanical transmission causes the limiting post 104b in the vibration assembly 104 to move stably within the fixing plate 104a of the clamping component 104e. The vibration spring 104c is forced to generate reciprocating vibration and drives the connecting plate 104d to move. The clamping component 104e uses the squeezing rod 104e-3 in conjunction with the return spring 104e-4 to make the clamping plate 104e-5 elastically clamp the limiting post 104b, ensuring vibration stability. This vibration is transmitted to the screen plate 105d through the snap-fit ​​component 105c. Under the action of the squeezing spring 105c-5, the telescopic rod 105c-4 pushes the snap-fit ​​block 105c-6 to form a stable connection with the support post 105b, so that the screen plate 105d generates uniform vibration. Seeds are graded according to particle size on the vibrating screen plate 105d. Qualified seeds are discharged through the screen holes and the feed plate 105e, while unqualified materials are retained above the screen plate 105d, realizing efficient and accurate seed screening.

[0035] In summary, the efficient and stable screening operation is achieved through the synergistic action of the pedal 102 drive and the elastic clamping mechanism. Its innovatively designed vibration component 104 adopts a limiting post 104b and a multi-stage spring buffer structure to ensure smooth vibration and adjustable amplitude. The unique clamping component 104e effectively prevents the components from loosening during operation through the elastic cooperation of the return spring 104e-4 and the clamping plate 104e-5. The modular design of the snap-fit ​​component 105c makes the screen plate 105d firmly installed and easy to replace. Combined with the optimized feeding channel, the screening efficiency is significantly improved. The overall structure is compact and reasonable, the operation is simple and labor-saving, it can achieve accurate seed grading, and it also has the advantages of convenient maintenance and long service life.
