However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] This embodiment provides, for example Figures 1 to 5 The fertilization device shown includes a fertilizer cart 1, on which a fertilizer box 2 is mounted. A fertilizer spreading box 7 is installed on one side of the fertilizer box 2 and on the top surface of the fertilizer cart 1. A semi-circular concave shell 8 is integrally formed at the bottom of the end of the fertilizer spreading box 7 away from the fertilizer box 2. A first support rod 13 and a second support rod 19 are respectively inserted through the center of both sides of the semi-circular concave shell 8. A servo motor 16 is fixed at one end of the second support rod 19 located in the cavity 15 of the semi-circular concave shell 8. A connecting shaft 20 is welded to the output shaft of the servo motor 16. The connecting shaft 20 is arranged in a ring around its periphery. Multiple fertilizer-spreading rotating blades 10 are welded together. The end of the connecting shaft 20 furthest from the servo motor 16 is welded to the first support rod 13. The servo motor 16 drives the multiple fertilizer-spreading rotating blades 10 to rotate within the cavity 15, causing the rotating blades 10 to propel the fertilizer in the cavity 15 out of the fertilizer spreading box 7 and into the sandy soil requiring fertilization. One side of the fertilizer spreading box 7 is connected to the second support rod 19 via a push-pull assembly, which drives the multiple fertilizer-spreading rotating blades 10 to move within the cavity 15. The fertilizer box 2 conveys fertilizer into the fertilizer spreading box 7 through a discharge component. The displacement of the fertilizer-spreading rotating blades 10 ensures that fertilizer is effectively distributed to different locations within the fertilizer spreading box 7. This design not only replaces manual labor but also improves the uniformity of fertilization.

[0029] In this embodiment, a pump mounting section 6 is provided between the fertilizer tank 2 and the fertilizer spreading tank 7. The discharge component includes a negative pressure pump installed in the pump mounting section 6, and an output end and an input pipe respectively connected to both ends of the negative pressure pump. The input pipe is connected to the input port 9 in the fertilizer spreading tank 7. Utilizing the pressure difference generated by the negative pressure pump, fertilizer can flow smoothly from the fertilizer tank into the fertilizer spreading tank. This method ensures a continuous supply of fertilizer, reduces manual intervention, and ensures the smoothness of the fertilization process.

[0030] In this embodiment, the push-pull assembly includes a push-pull connecting plate 18 welded to the free end of the second support rod 19 and an electric push-pull rod 17 fixed to the lower part of the inner wall of the push-pull connecting plate 18. The tail end of the electric push-pull rod 17 is bolted to the outer wall of the fertilizer spreading box 7. The electric push-pull rod 17 extends and retracts to push and pull the push-pull connecting plate 18, thereby enabling the push-pull connecting plate 18 to drive the second support rod 19 to move, which in turn causes the second support rod 19 to drive the servo motor 16 and the fertilizer spreading rotating blade 10 to move in the cavity 15.

[0031] In this embodiment, a mounting support end 12 is provided at one end of the fertilizer spreading box 7 near the fertilizer box 2. The mounting support end 12 is welded to one end of the top surface of the fertilizer cart 1. A tail end cover 11 is welded to the top surface of the mounting support end 12, and the tail end cover 11 is located above the inlet 9. This prevents fertilizer from being thrown into the pump body mounting part 6 and reduces fertilizer splashing.

[0032] In this embodiment, a vibrating screen chamber 21 is provided between the inlet 9 and the recess 15. A discharge slide plate 14 is installed above the vibrating screen chamber 21 by screws. The discharge slide plate 14 is inclined between the inlet 9 and the recess 15 to allow fertilizer to slide down from the inlet 9 into the recess 15. The inclined design utilizes gravity to guide the fertilizer to slide down naturally, avoiding blockage and ensuring smooth fertilizer flow, reducing fertilization interruptions or unevenness caused by blockage.

[0033] In this embodiment, a vibrating screen component is provided below the material discharge slope plate 14 and in the vibrating screen cavity 21. The vibrating screen component includes a vibrating screen motor 22 installed on the inner wall of one side of the mounting support end 12 and a vibrating screen eccentric plate 23 fixed on the output shaft of the vibrating screen motor 22.

[0034] In this embodiment, when the vibrating screen motor 22 drives the vibrating screen eccentric plate 23 to rotate eccentrically, the eccentric end of the vibrating screen eccentric plate 23 impacts the back of the discharge slide plate 14, causing the fertilizer accumulated on the discharge slide plate 14 to slide into the cavity 15.

[0035] In this embodiment, a silicone protective pad is bonded to the eccentric end of the vibrating screen eccentric plate 23, and the silicone protective pad is in dynamic contact with the back of the discharge slip plate 14. The silicone material provides cushioning and protection, reduces noise and wear, and extends the service life of the equipment.

[0036] In this embodiment, a positioning key block 24 is welded to the outer wall of the second support rod 19. The positioning key block 24 passes through the semi-circular concave shell 8 along with the second support rod 19, so that the pushing and pulling operation of the second support rod 19 is positioned by the positioning key block 24.

[0037] In this embodiment, the bottom surface of the fertilizer cart 1 is provided with wheels 3, the outer wall of the end of the fertilizer cart 1 facing away from the fertilizer spreading box 7 is welded with a cart handle 4, the top surface of the fertilizer box 2 is equipped with a box cover 5, and the top surface of the box cover 5 is equipped with a handle.

[0038] Working principle

[0039] This fertilization device for high-altitude sandy areas has a fertilizer tank 2 filled with sufficient fertilizer and sealed with a lid 5. A pushcart handle 4 and wheels 3 make the entire fertilization cart 1 easy to move to the desired fertilization location. When fertilization begins, a negative pressure pump is installed in the pump body mounting section 6. After startup, fertilizer is drawn from the fertilizer tank 2 through the input pipe and transported to the input port 9 in the fertilizer spreading box 7. The negative pressure pump plays a crucial role in ensuring the fertilizer flows smoothly from the fertilizer tank 2 to the fertilizer spreading box 7. Before entering the fertilizer spreading box 7, the fertilizer passes through a vibrating screen chamber 21. The vibrating screen component here is driven by a vibrating screen motor 22, which causes the vibrating screen eccentric plate 23 to rotate eccentrically, thereby impacting the back of the discharge slope plate 14. This loosens the fertilizer accumulated on the discharge slope plate 14 and allows it to slide smoothly into the concave cavity 15. This process helps prevent fertilizer clumping and ensures uniform fertilizer distribution.

[0040] The servo motor 16 drives the coupling shaft 20 and multiple fertilizer spreading rotary blades 10 welded to it to rotate at high speed in the cavity 15. The rotational force throws fertilizer from the fertilizer spreading box 7 into the sandy soil. The push-pull assembly controls the second support rod 19 and the servo motor 16 and fertilizer spreading rotary blades 10 connected to it to move back and forth to ensure the uniformity of fertilizer application. The tail end cover 11 is located above the inlet 9 to prevent fertilizer from splashing onto the pump body mounting part 6 during high-speed rotation, reducing unnecessary losses and equipment contamination.

[0041] By adjusting the telescopic length of the electric push-pull rod 17, the position of the fertilizer-spreading rotating blade 10 within the cavity 15 can be changed, enabling precise fertilization of different areas. The positioning key block 24, along with the second support rod 19, passes through the semi-circular concave shell 8, ensuring the operational stability and accuracy of the second support rod 19.
