[0002] To ensure seed survival rates during sowing, and to provide pest control and nutrient supply in the early stages after sowing, seed pretreatment is often performed before sowing. This involves mixing in a certain amount of additives and forming a coating layer on the seed surface through a shaking process. This coating layer protects the seeds after sowing, providing the necessary nutrients for germination and offering long-term control over pests and diseases. Existing seed coating equipment is designed for large-scale mass production, integrating power, feeding, and discharging systems. This makes it unsuitable for small-scale production or experimental fields. Therefore, a portable, low-cost, simple, and easy-to-operate seed coating device is needed for experimental fields or small-scale farming. Summary of the Invention

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] As shown in Figures 1-4, the specific implementation adopts the following technical solution:

[0028] This specific embodiment includes a base 1, a frame 2, a shaking disc 3, and a screen 9. The frame 2 is fixedly mounted on the base 1. Two support shafts 4 are spun onto the frame 2 via bearings. A support frame 5 is fixedly mounted on the upper end of each support shaft 4. A support rod 6 is fixedly mounted on the support frame 5. A support sleeve 7 is movably sleeved on the support rod 6. A support seat 8 is mounted above the support frame 5. Both ends of the support seat 8 are spun onto the two support sleeves 7 via bearings. A support sleeve 7 is fixedly mounted on the upper side wall of the support seat 8. A support column is fixedly mounted on the lower side wall of the shaking disc 3. The support column is inserted into the support sleeve 7, thereby enabling the shaking disc 3 to be mounted on the support seat 8 or removed from the support seat 8. A support spring 12 is sleeved on the support rod 6. One end of the spring 12 is fixedly mounted on the support rod 6, and the other end of the support spring 12 is fixedly mounted on the support sleeve 7. The support frame 5 drives the shaking disc 3 to oscillate in a circular motion. When the oscillation accelerates, the centrifugal force causes the support seat 8 to slide on the support rod 6 through the support sleeve 7, causing the support seat 8 to shift away from the center and thus increasing its eccentric distance. At this time, the support spring 12 is pressed tight. When the rotational speed of the support seat 8 decreases, the support spring 12 pushes the support sleeve 7 to return to its original position, thus reducing the eccentric distance of the support seat 8. The upper end of the frame 2 is fixedly mounted with a mounting frame 16. Guide sleeves 19 are symmetrically fixedly mounted on the left and right inner walls of the mounting frame 16. A screening frame 17 is installed inside the mounting frame 16, and the screen 9 is movably embedded in the screening frame. Inside the 17, guide rods 18 are fixedly installed on both the left and right side walls of the screening frame 17. The guide rods 18 are movably inserted into the guide sleeves 19. A return spring 20 is sleeved on the right guide rod 18, and the return spring 20 is clamped between the screening frame 17 and the right guide sleeve 19. A ratchet wrench unit 14 is fixedly installed on the side wall of the frame 2. The ratchet wrench unit 14 includes a shaft structure and a handle structure set on the shaft structure through a one-way ratchet set, so as to realize the reciprocating motion of the handle structure to drive the one-way rotation of the shaft structure. A drive shaft 15 is screwed onto the frame 2 through bearings. The shaft structure of the ratchet wrench unit 14 and the drive shaft 15 are connected by a bevel gear set. A transmission shaft 13 is screwed onto the frame 2 through bearings. The drive shaft 13 is connected to the two support shafts 4 via bevel gear sets. The drive shaft 13 is also connected to the drive shaft 15 via bevel gear sets. A connecting rod 22 is fixedly mounted on the screen frame 17 and is movably mounted on the right side plate of the mounting frame 16. A hook 23 is screwed onto the connecting rod 22 via a bearing with a damping structure. A crankshaft 21 is fixedly mounted on the upper end of the drive shaft 15. The crank end of the crankshaft 21 is engaged with the hook 23. The crankshaft 21 rotates to hook the hook 23, thereby pulling the screen frame 17 by rotating the connecting rod 22. When the crankshaft 21 slips off the hook 23, the screen frame 17 quickly springs back to its original position. Alternatively, the hook 23 can be rotated to adjust its position and orientation, so that the crankshaft 21 rotates without contacting the hook 23.

[0029] When using this device, seeds are placed in the shaking tray 3, and coating material is placed in the sieve tray. By repeatedly pressing the handle of the ratchet wrench unit 14, the drive shaft 15 is driven to rotate continuously in one direction. The drive shaft 15 drives the transmission shaft 13 to rotate through the bevel gear set. The transmission shaft 13 then drives the two support shafts 4 to rotate synchronously in the same direction. The two support shafts 4 drive the two support frames 5 to make synchronous circular motions. The two support frames 5 drive the support base 8 to make a circumferential motion of translation. The support base 8 causes the shaking tray 3 to shake in a circular motion. The drive shaft 15 drives the crankshaft 21 to rotate. After the crank end of the crankshaft 21 rotates and hooks the hook 23, the crankshaft 21 passes through the hook 23. Pulling the connecting rod 22 moves the screening frame 17, which in turn moves the screen 9. The screening frame 17 also moves the guide rod 18, which slides within the guide sleeve 19 and presses the return spring 20. After the crankshaft 21 pulls the screening frame 17 and disengages from the hook 23, the return spring 20 pushes the screening frame 17 to move rapidly in the opposite direction until the screening frame 17 abuts against the mounting frame 16. This reciprocating motion of the screening frame 17 causes it to impact the mounting frame 16, which in turn causes the screen 9 to vibrate and screen the material. The shaking disc 3 also vibrates, causing the seeds within the shaking disc 3 to shake. The powder from the screen 9 falls off, thus allowing the coated material to be screened out and the seeds to be coated through shaking.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] 1. This device is equipped with a shaking disc 3 that makes circular motion, and a reciprocating vibrating screen 9 is set above the shaking disc 3, so as to realize the addition of seed material into the shaking disc 3 and the addition of coating powder into the screen 9. By shaking the seeds and the screened powder, the seed coating process is realized.

[0032] 2. This device sets two sets of support frames 5 driven by support shaft 4 on the frame 2, thereby driving the support base 8 through the two sets of support frames 5, and installing the shaking plate 3 on the support base 8 to realize the shaking of the shaking plate 3;

[0033] 3. This device is equipped with a screening frame 17 supported by a guide sleeve 19 and a guide rod 18. The screen 9 is installed on the screening frame 17. A crankshaft 21 driven by a drive shaft 15 is provided and cooperates with the hook 23 on the connecting rod 22. The connection between the connecting rod 22 and the screening frame 17, along with the return spring 20, enables the vibration drive of the screening frame 17 by the crankshaft 21, that is, the screen 9 shakes to screen the material.

[0034] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
