[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example is used to solve the problem that existing corn fertilizer planters are difficult to adjust the frequency of fertilizer application, have poor flexibility, and are difficult to adapt to different types of fertilizers and different fertilization needs.

[0025] Please see Figure 1 - Figure 5 As shown, this embodiment is a precision fertilization structure suitable for corn planters, including a frame 1. Two symmetrically arranged connecting seats 4 are fixedly connected to the upper surface of the frame 1. A storage box 5 is fixedly connected between the two connecting seats 4. A feeding box 7 is fixedly connected to the bottom end of the storage box 5. The feeding box 7 is a common fertilization and sowing key shaft type in the art. An adjustment mechanism is provided on the feeding box 7.

[0026] The adjustment mechanism includes a rotating rod 6 that passes through the feeding box 7 and is axially slidably connected to the feeding box 7. The rotating rod 6 passes through and is fixedly connected to a transmission disk 10. The surface of the transmission disk 10 is provided with an annular array of sliding grooves. A moving block 15 is slidably connected in the sliding groove of the transmission disk 10. The moving block 15 moves in the sliding groove on the surface of the transmission disk 10. The inner diameter of the transmission disk 10, which is composed of multiple moving blocks 15, changes, thereby enabling the adjustment of the inner diameter.

[0027] A rotating shaft 8 is rotatably connected to the inner side of the frame 1. The rotating shaft 8 and multiple moving blocks 15 are fitted with a belt 9. The multiple moving blocks 15 move in the sliding groove on the surface of the corresponding transmission disc 10, thereby adjusting the rotation speed of the rotating rod 6. By adjusting the rotation speed of the rotating rod 6, the spacing of the fertilizer can be precisely controlled.

[0028] A movable sleeve 18 is axially slidably connected to the rotating rod 6. The movable sleeve 18 is axially slidably connected to the rotating rod 6. The movable sleeve 18 moves along the direction of the rotating rod 6 while rotating with the rotating rod 6. Multiple movable rods 16 are movably connected to the movable sleeve 18 through pins. The movable rods 16 are movably connected to the moving blocks 15 through pins. Pushing the movable rods 16 toward the transmission disk 10 can move the multiple moving blocks 15 away from the center of the transmission disk 10, thereby adjusting their inner diameter.

[0029] A connecting sleeve 19 is slidably connected to the rotating rod 6 through and limited by the rotating rod 6. The rotating rod 6 has a limiting groove for slidably connecting to the connecting sleeve 19. The connecting sleeve 19 is rotatably connected to the movable sleeve 18. A screw 17 is screwed through and screwed onto the outer wall of the connecting seat 4. The screw 17 is rotatably connected to the surface of the connecting sleeve 19. Rotating the screw 17 pushes the connecting sleeve 19 to move on the rotating rod 6, which allows the movable sleeve 18, which is rotatably connected to the connecting sleeve 19, to move along the direction of the rotating rod 6, thereby adjusting the inner diameter of the multiple moving blocks 15 on the inner side of the transmission disc 10.

[0030] A connecting column 2 is fixedly connected to the inner wall of the frame 1. A clamp 3 is fitted on the connecting column 2. A sleeve for inserting a hose is welded to the surface of the clamp 3. Loosen the screw on the clamp 3 and then push the clamp 3 to move on the connecting column 2. Adjust the position of the sleeve on the surface of the clamp 3 to adjust the horizontal fertilization position.

[0031] Example 2: This example addresses the issue of how to improve the stability of the adjustment mechanism to further ensure precise control of fertilizer application spacing.

[0032] Please see Figure 1 - Figure 5 As shown in the figure, a precision fertilization structure suitable for a corn planter in this embodiment has a rotating shaft 8 through which a connecting rod 11 is fixedly connected. A connecting block 12 is slidably connected horizontally to one side of the inner wall of the connecting seat 4. The connecting block 12 is U-shaped. A limiting rod is fixedly connected to one side of the connecting block 12, which passes through the connecting seat 4 and is slidably connected to the inner wall of the connecting seat 4 to limit the movement direction of the connecting seat 4. A pulley that is sleeved on the belt 9 is rotatably connected to the inner wall of the connecting block 12. When the connecting block 12 moves, the pulley on the connecting block 12 pulls the belt 9, which can adjust the tension of the belt 9, thereby ensuring the tension of the belt 9 when adjusting the inner diameter of the transmission disc 10.

[0033] A connecting piece 13 is fixedly connected to one side of the inner wall of the connecting seat 4. The connecting piece 13 is penetrated and screwed with a screw 14. The end of the screw 14 is rotatably connected to the connecting block 12. When the screw 14 is rotated, the screw 14 pulls the connecting block 12 to move. The connecting block 12 pulls the belt 9 to fit tightly with the roller on the connecting block 12, thereby ensuring the tension of the belt 9 and enabling the rotating rod 6 and the rotating shaft 8 to transmit power stably from left to right on the belt 9.

[0034] Combining Example 1 and Example 2

[0035] By setting an adjustment mechanism, the fertilizer application spacing can be precisely controlled. By adjusting the rotation speed of the rotating rod 6, the fertilizer application frequency can be further fine-tuned to avoid over- or under-application, thereby improving the accuracy and efficiency of fertilization. The transmission disc 10 and moving block 15 in the adjustment mechanism are designed with adjustable inner diameters to adapt to different types of fertilizers and different fertilization needs. By adjusting the tension of the belt 9, not only is the transmission efficiency improved, but the transmission stability is also enhanced, allowing the belt 9 to maintain appropriate tension, thereby ensuring stable transmission between the rotating rod 6 and the rotating shaft 8, further guaranteeing precise control of the fertilizer application spacing. The adjustable tension design of the belt 9 further improves the stability and efficiency of the transmission, making the structure more adaptable and reliable in practical applications.
