The fertilization component 2 is connected to the discharge component 3 via a pipe. The adjustment component 1 includes a mounting frame 13. The mounting frame 13 has three sliding grooves 15 on both its upper and lower sides, and a first sliding groove 110 on its front side. Multiple movable plates 14 are movably fitted onto the mounting frame 13 and slidably connected to the three sliding grooves 15. A rack structure 11 is provided on the lower side of the first sliding groove 110. A fixing frame 19 is fixed to the inner wall of the movable plate 14, and the fixing frame 19 is fixed to the adjustment plate 112. The adjustment plate 112 is movably set to fit against the inner wall of the first sliding groove 110. A second sliding groove 113 is provided on the 112. A fixed plate 17 is movably disposed against the inner wall of the second sliding groove 113. One end of the fixed plate 17 has a strip-shaped slot 111, which is inclined. An adjusting rod 16 passes through one side of the fixed frame 19, and a connecting post 18 is fixed to its end. A return spring 114 is sleeved on the adjusting rod 16. One end of the return spring 114 is fixedly connected to the adjusting rod 16, and the other end is fixedly connected to the fixed frame 19. One end of the connecting post 18 is movably disposed in the strip-shaped slot 111. The end of the fixed plate 17 has a serrated structure and is fixed in conjunction with the rack structure 11. A connecting plate 12 is fixed on the movable plate 14. (Discharge) Component 3 is installed on connecting plate 12. Fertilizer assembly 2 includes fertilizer box 22, which has a trapezoidal structure. Multiple fertilizer boxes 23 are connected through the bottom of fertilizer box 22. Rotating rod 26 is installed through fertilizer box 23 via bearing, and one end of rotating rod 26 is connected to the output end of self-locking motor 21 via coupling. Rotating wheel 25 is fixedly sleeved on rotating rod 26. Rotating wheel 25 is movably arranged against the left and right inner walls of fertilizer box 23. Two blades 24 are symmetrically fixed on rotating wheel 25. Blades 24 are movably arranged against the front and rear inner walls of fertilizer box 23. Funnel 27 is installed through the lower part of fertilizer box 23. Transport pipe 28 is connected below funnel 27. 8 is a corrugated hose. The lower end of the transport pipe 28 is connected to the discharge assembly 3. The discharge assembly 3 includes a sleeve 31. An installation plate 32 is fixed on the upper part of the sleeve 31. The sleeve 31 is bolted to the connecting plate 12 and the installation plate 32 and fixed to the connecting plate 12. A discharge port 34 is opened at the lower part of the sleeve 31.

The plow blade 35 is buried on the side of the wheat that needs to be fertilized. The agricultural vehicle and the self-locking motor 21 are started. The plow blade 35 turns the soil. The self-locking motor 21 drives the rotating rod 26 to rotate. The rotating rod 26 drives the rotating wheel 25 to rotate. Under the action of the blade 24, the fertilizer enters the sleeve 31 through the transport pipe 28 and falls into the turned soil from the discharge port 34. The covering plate 33 covers the turned soil again.

[0021] Compared with the prior art, the beneficial effects of this specific embodiment are:

[0022] 1. Through the cooperation of the movable plate and the slide groove three, the adjusting rod, through the cooperation of the connecting column and the strip groove, fixes the fixed plate and the rack structure, which can meet different fertilization spacing and can also self-lock with weight.

[0023] 2. By fitting the rotor and blades into the inner wall of the fertilizer box, and in conjunction with the self-locking motor, the fertilization speed can be adjusted by regulating the speed of the self-locking motor.

[0024] 3. By using a plow and a soil covering board, fertilizer can be buried in the soil while the turned-up soil is covered back up.

[0025] 4. The combination of corrugated hose and threaded structure allows for easy adjustment of the discharge assembly spacing.

[0026] 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.
