[0002] In modern agricultural production, sowing is a crucial initial step in crop cultivation, with strict requirements for both efficiency and quality. Different crop seeds vary significantly in shape, size, and weight, necessitating the use of different types of seed reels for precise sowing.

[0003] In practical use, it has been found that the seeding wheel of traditional seeders is usually a fixed structure, connected to the seeder drive shaft by welding or bolting. Once the type of seeding operation changes, the entire seeder needs to be replaced, which is cumbersome, time-consuming and labor-intensive, and greatly increases the cost of agricultural production. Therefore, we have proposed a universal detachable and interchangeable seeding wheel for seeders to solve the above problems. Utility Model Content

[0037] Specifically, the first limiting mechanism includes a pull plate 4, a first limiting post 401, and a first limiting groove 402. The same pull plate 4 is slidably installed on the front inner wall and the rear inner wall of the vertical cavity. The first limiting post 401 is fixedly installed on the right side of the pull plate 4. The left end of the first limiting post 401 extends into the shaft hole 101, and the right end of the first limiting post 401 extends to the outside of the mounting base 2. The right side of the drive shaft 3 has a first limiting groove 402, and the first limiting post 401 is engaged with the first limiting groove.

[0038] Specifically, a spring 404 is fitted on the first limiting post 401, and the two ends of the spring 404 are fixedly connected to the right side of the pull plate 4 and the inner wall of the right side of the vertical cavity, respectively.

[0039] Specifically, a pull button 403 is fixedly installed on the right end of the first limiting post 401.

[0040] Specifically, the lead screw mechanism includes two lead screws 5 and two lead screw seats 501. The same lead screw 5 is rotatably installed on the inner wall of the top and bottom of the transverse cavity. The lead screw 5 is threaded with a lead screw seat 501. A gear mechanism is provided between the lead screw 5 and the pull plate 4.

[0041] Specifically, the second limiting mechanism includes a second limiting post 502 and a second limiting groove 503. The second limiting post 502 is fixedly installed on the adjacent side of the two lead screw seats 501.

[0042] Specifically, the same fixing rod 8 is fixedly installed on the inner wall of the top and bottom of the vertical cavity. The fixing rod 8 is located to the right of the lead screw 5, and the lead screw seat 501 is slidably sleeved on the fixing rod 8.

[0043] Specifically, the fixing mechanism includes a screw 701 and a groove 702. The screw 701 is threadedly installed on the top of the fixing plate 7. The bottom end of the screw 701 extends to the bottom of the fixing plate 7. The top of the pull button 403 has a groove 702. The screw 701 is adapted to the groove 702. The top of the screw 701 is fixedly installed with a knob 703.

[0044] Specifically, the gear mechanism includes a gear 6 and a rack plate 601. The rack plate 601 is fixedly installed on the left side of the pull plate 4.

[0045] In this application, before sowing, the appropriate sowing wheel 1 needs to be replaced according to different crop types. During disassembly, the operator first rotates the knob 703 on the fixed plate 7, causing the screw 701 to rise and disengage from the groove 702 of the pull knob 403, thus releasing the lock on the pull knob 403. By pulling the pull knob 403, the pull plate 4 can be moved to the right, causing the first limiting post 401 to disengage from the first limiting groove 402 of the drive shaft 3, while compressing the spring 404 to store elastic potential energy. The rightward movement of the pull plate 4 can drive the lead screw 5 to rotate through the rack plate 601 and the gear 6, causing the lead screw seat 501 to slide along the fixed rod 8, thus causing the second limiting post 502 to disengage from the second limiting groove 503 of the drive shaft 3, thereby releasing both the axial and circumferential constraints between the sowing wheel 1 and the drive shaft 3. The new seeding wheel 1 can be easily removed along the mating direction of the guide bar 301 and the guide groove 201. During installation, by aligning the shaft hole 101 of the new seeding wheel 1 with the drive shaft 3, the guide bar 301 and the guide groove 201 can ensure quick and accurate alignment. By releasing the pull button 403, the spring 404 can push the pull plate 4 to the left to reset, allowing the first limiting post 401 to be engaged in the first limiting groove 402 for initial positioning. Rotating the knob 703 causes the screw 701 to be inserted into the rod groove 702, locking the position of the pull button 403. At the same time, the lead screw 5 rotates in the opposite direction, driving the lead screw seat 501 to move, causing the second limiting post 502 to be engaged in the second limiting groove 503, thus forming a double limiting structure. This ensures the circumferential positioning accuracy of the seeding wheel 1 on the drive shaft 3, thereby enabling convenient replacement of the seeding wheel 1.
