[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a medicine spraying device for treating contaminated cultivated land soil, including a housing 1. The inner wall of the housing 1 is slidably connected with a rolling frame 2 through a lifting assembly. The inner wall of the rolling frame 2 is rotatably connected with a roller 4. The roller 4 is used for rolling the agglomerated soil to keep the soil soft and better absorb the medicine. Both sides of the bottom of the outer wall of the rolling frame 2 are fixedly connected with sliding shovels 5. The ends of the sliding shovels 5 are provided with inclined surfaces for shoveling and treating the soil. The left side of the outer wall of the rolling frame 2 is fixedly connected with an auxiliary block 6. The auxiliary block 6 is set as a square block for keeping the rolling frame 2 sliding vertically up and down, preventing the rotating roller 4 from driving the rolling frame 2 to tilt and deviate, and causing damage to the motor 3. A chute 7 is opened on the right side of the outer wall of the housing 1 for the output shaft of the motor 3 to slide. A fixed chute 8 is opened on the right side of the outer wall of the housing 1 for the fixed frame 9 to slide, so that the motor 3 always keeps sliding vertically up and down. The inner wall of the fixed chute 8 is slidably connected with a fixed frame 9. The inner wall of the fixed frame 9 is fixedly connected with a motor 3. A chute 10 is opened on the left side of the outer wall of the housing 1. A fixed slot 11 is opened on the back of the housing 1. The fixed slot 11 is provided with several groups, and the number can be changed according to actual needs. A fixing assembly is arranged on the back of the housing 1. A limiting ring 20 is fixedly connected to the top left of the housing 1. A limiting groove 21 is opened on the inner wall of the limiting ring 20 for clamping the limiting block 19, so that the opposing threaded rod 14 remains stationary and does not rotate without external force, avoiding the sliding shovel 5 being pressed and rising. Several groups of spraying seats 28 are slidably connected to the inner wall of the back of the housing 1. The outer wall of the auxiliary block 6 is slidably connected to the inner wall of the chute 10. The outer wall of the sliding shovel 5 is slidably connected to the inner wall of the housing 1.

[0033] Referring to Figures 2 - 4, the fixing component includes a fixing rod 22, the outer wall of the fixing rod 22 is slidably connected to the inner wall of the fixing groove 11, and the height of the connecting seat 24 is adjusted by clamping different fixing grooves 11 with the fixing rod 22. The outer wall of the fixing rod 22 is elastically connected with a connecting seat 24 through a fixing spring 23. Due to the opposite extrusion force between the fixing spring 23 and the connecting seat 24, the fixing rod 22 is always clamped on the inner wall of the fixing groove 11 without being affected by external forces, preventing disengagement and limit release, which may cause a change in the spraying range. Both sides of the outer wall of the connecting seat 24 are hinged with connecting rods 25, and the bottom ends of the connecting rods 25 are hinged to the bottom outer wall of the outermost spraying seat 28. Multiple groups of spraying seats 28 are hinged by a first connecting rod 26 and a second connecting rod 27. By the downward movement of the connecting seat 24 to squeeze the connecting rods 25 to make an unfolding movement, several groups of spraying seats 28 are driven by the connecting rods 25 to unfold, realizing the adjustment of the spraying range. The outer wall of the fixing rod 22 is slidably connected to the inner wall of the connecting seat 24. One end of the fixing spring 23 is fixedly connected to the inner wall of the connecting seat 24, and the other end of the fixing spring 23 is fixedly connected to the outer wall rim of the fixing rod 22. The outer wall of the connecting seat 24 is slidably connected to the outer wall of the housing 1.

[0034] Refer to Figures 3 - 5 , the lifting component includes lifting rods 12. There are two groups of lifting rods 12. The bottom ends of the two groups of lifting rods 12 are both hinged to the top of the rolling frame 2. The top ends of the two groups of lifting rods 12 are both hinged with threaded blocks 13. The inner walls of the two groups of threaded blocks 13 are threadedly connected with an oppositely threaded rod 14. By rotating the oppositely threaded rod 14, the threaded blocks 13 are driven to move inward or outward. By the threaded blocks 13, the lifting rods 12 are driven to make a sector movement, realizing the rising and falling effect of the rolling frame 2. A clamping groove 15 is opened at the end of the oppositely threaded rod 14. The clamping groove 15 is set in a shape corresponding to the clamping block 17 for clamping the clamping block 17. A limiting component is clamped on the inner wall of the clamping groove 15. The oppositely threaded rod 14 passes through and is rotatably connected to the inner wall of the housing 1. The bottom of the outer wall of the threaded block 13 is slidably connected to the top of the inner wall of the housing 1. The limiting component includes a clamping block 17. The clamping block 17 is elastically connected to the inner wall of the clamping groove 15 through a limiting spring 16. The clamping block 17 is square, enabling it to slide in the clamping groove 15 and also enabling the oppositely threaded rod 14 to be rotated through the clamping groove 15. The outer end of the clamping block 17 is a limiting base 18. The limiting base 18 is provided with a crank for manually rotating the oppositely threaded rod 14 more labor-saving. A limiting block 19 is fixedly connected to the outer wall end of the limiting base 18. There are eight groups of limiting blocks 19 arranged around the outer diameter of the limiting base 18 for multi-directional limiting, and different numbers can be changed according to actual needs. The outer wall of the clamping block 17 is slidably connected to the inner wall of the clamping groove 15. One end of the limiting spring 16 is fixedly connected to the inner wall of the clamping groove 15, and the other end of the limiting spring 16 is fixedly connected to the outer wall of the limiting base 18. The outer wall of the limiting block 19 is clamped on the inner wall of the limiting groove 21. The outer wall of the limiting base 18 is slidably connected to the inner wall of the limiting ring 20.

[0035] Working principle: When the height of soil turning during plowing is different, the limit is released by manually pulling the limit base 18 to drive the limit block 19 out of the limit groove 21. Then, manually rotate the limit base 18 to drive the opposite threaded rod 14 to rotate through the clamping block 17. Drive the threaded block 13 to move horizontally through the opposite threaded rod 14. Drive the lifting rod 12 to perform a fan-shaped movement by the inward or outward movement of the threaded block 13. Drive the roller pressing frame 2 to rise or fall through the lifting rod 12. Drive the sliding shovel 5 to rise or fall to the required height through the roller pressing frame 2. Then, release the limit base 18, and the limit block 19 is rebounded into the limit groove 21 by the limit spring 16 for clamping and limiting, completing the adjustment and fixation of the soil turning height, and improving the efficiency of soil treatment and medicine spraying during plowing.

[0036] When the range of medicine spraying is different, the limit is released by pulling the fixing rod 22 out of the fixing groove 11. Then, lift or lower the connecting seat 24 to drive the connecting rod 25 to expand or contract. Drive the outermost two groups of spray seats 28 to extend or contract through the connecting rod 25. Then, drive several groups of spray seats 28 to extend or contract to the required position through the first connecting rod 26 and the second connecting rod 27. Then, release the fixing rod 22, and it is rebounded into the corresponding fixing groove 11 by the fixing spring 23 for clamping and fixing, completing the adjustment and fixation of the spray medicine position, and avoiding waste of medicine and causing economic losses to farmers.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
