[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figures 1-6 A soil treatment device for polluted farmland includes a vehicle body 1. A material tank 5 is installed on the top of the vehicle body 1. The material tank 5 is equipped with a stirring mechanism to facilitate the mixing of chemical modifier solution. One side of the material tank 5 near the bottom is connected to one end of a pump 14 installed on the top of the vehicle body 1 via a connecting pipe 13. The other end of the pump 14 is connected to a spray gun 15 via a connecting pipe 13. A base box 16 is provided on the top of the vehicle body 1. A base frame 18 is rotatably connected to the top of the base box 16. A drive mechanism is installed on the inner side of the base box 16 to facilitate the reciprocating swing of the base frame 18. A mounting frame 33 is provided on the top of the base frame 18. An adjustment mechanism is installed on the inner side of the base frame 18 to facilitate the angle adjustment of the mounting frame 33. The spray gun 15 is connected to the top of the mounting frame 33 via a clamping mechanism that facilitates disassembly and assembly.

[0027] The clamping mechanism includes an electric telescopic rod 41. The inner side of the mounting frame 33 is provided with two sets of support rods 37 and two sets of movable seats 38 are slidably connected. Each side of the two sets of movable seats 38 is provided with a set of rack plates 39. Both sets of rack plates 39 mesh with a second spur gear 40 rotatably connected to the inner side of the mounting frame 33. An electric telescopic rod 41 is installed on one side of the mounting frame 33. One end of the electric telescopic rod 41 extends to the inner side of the mounting frame 33 and is connected to one side of the set of movable seats 38. The top of the mounting frame 33 is provided with two sets of through slots 43. The top of the mounting frame 33 is slidably connected with two sets of connecting plates 44. The bottom of the two sets of connecting plates 44 passes through the inner side of the two sets of through slots 43 and is connected to the two sets of movable seats 38 respectively. Each side of the two sets of connecting plates 44 is provided with a clamping plate 45.

[0028] Specifically, the vehicle body 1 provides a stable working platform for spraying the chemical modifier solution. The pump 14 extracts the chemical modifier solution from the tank 5 and sprays it through the spray gun 15 for spraying contaminated soil. The stirring mechanism facilitates stirring of the chemical modifier solution, effectively improving its uniformity and preventing sedimentation. Activating the electric telescopic rod 41 moves a set of movable seats 38 towards the center of the mounting frame 33. The movable seats 38 move a set of rack plates 39 to one side. The rack plates 39, meshing with the second sprocket 40, rotate the second sprocket 40. 40, through meshing with another set of rack plates 39, can drive the other set of rack plates 39 and the other set of moving seats 38 to move in opposite directions. Thus, the two sets of moving seats 38 can drive the two sets of connecting plates 44 to move towards the center position. The two sets of connecting plates 44 can drive the two sets of clamping plates 45 to move towards the center position and clamp and fix the spray gun 15. Through reverse operation, the spray gun 15 can be disassembled. Through the set adjustment mechanism, the spraying angle of the spray gun 15 can be easily adjusted. Through the set drive mechanism, the spray gun 15 can be driven to rotate continuously, thereby increasing the spraying range of the spray gun 15. Thus, through the above structure, it can replace the manual spraying operation of the workers, effectively reducing the labor intensity of the workers, and improving the spraying effect of the chemical modifier solution.

[0029] Both sets of clamping plates 45 are V-shaped, and each of the two sets of movable seats 38 has a corresponding movable groove 42 on one side to facilitate the movement of the rack plate 39. The V-shaped clamping plates 45 can be used to clamp and fix spray guns 15 of different specifications, and the movable grooves 42 facilitate the movement of the rack plate 39.

[0030] The drive mechanism includes a second motor 30. The bottom of the base frame 18 is rotatably connected to the base box 16 via a rotating shaft 17. One end of the rotating shaft 17 extends to the inside of the base box 16 and is connected to a first spur gear 19. A first fixed frame 20 is provided on the top inner side of the base box 16. A vertical rod 21 is rotatably connected to the inner side of the first fixed frame 20. A rotating seat 22 is sleeved on the outer ring of the vertical rod 21. A sector plate 23 is connected to one side of the rotating seat 22. One end of the sector plate 23 has teeth 24 that mesh with the first spur gear 19. A swing plate 25 is provided on one side of the rotating seat 22 below the sector plate 23. A contact groove 26 is opened at the bottom of the swing plate 25. A second fixed frame 29 is provided on the top inner side of the base box 16 away from the first fixed frame 20. A second motor 30 is installed at the bottom of the second fixed frame 29. The output end of the second motor 30 extends to the inside of the second fixed frame 29 and is connected to a rotating rod 28. A contact rod 27 is provided at the top of one end of the rod 28. One end of the contact rod 27 passes through the inner side of the contact groove 26. By starting the second motor 30, the second motor 30 can drive the rotating rod 28 to rotate, and the rotating rod 28 can drive the contact rod 27 to rotate. Under the action of contacting the contact groove 26, the contact rod 27 can drive the swing plate 25 and the rotating seat 22 to swing back and forth around the upright rod 21 as the axis, thereby driving the sector plate 23 to rotate back and forth. Through the meshing action of the teeth 24 provided at one end of the sector plate 23 with the first spur gear 19, the first spur gear 19 can be driven to rotate back and forth. The first spur gear 19 can drive the rotating shaft 17 and the base frame 18 connected to its top to rotate back and forth. Thus, the base frame 18 can drive the mounting frame 33 and the spray gun 15 mounted on its top to rotate back and forth. In this way, the spraying range of the spray gun 15 can be effectively increased, and the spraying efficiency of the chemical modifier solution can be greatly improved.

[0031] The adjustment mechanism includes a third motor 36. A turbine disk 31 passes through the inner side of the base frame 18. A connecting shaft 32, which is rotatably connected to the base frame 18, passes through the interior of the turbine disk 31. The turbine disk 31 is located at the bottom of the mounting frame 33. A worm gear 34 is engaged with the turbine disk 31. The worm gear 34 is rotatably connected to the inner side of two sets of fixing plates 35. Both sets of fixing plates 35 are located at the bottom inner side of the base frame 18. One end of the worm gear 34 is connected to the output end of the third motor 36 installed on one side of the fixing plate 35. By starting the third motor 36, the third motor 36 can drive the worm gear 34 to rotate. The worm gear 34, through its engagement with the turbine disk 31, can drive the turbine disk 31 to rotate. The turbine disk 31 can rotate the mounting frame 33, thereby driving the spray gun 15 mounted on its top to rotate, so as to adjust the spray angle of the spray gun 15. This greatly improves the flexibility of the spray gun 15.

[0032] The mixing mechanism includes a first motor 11. A turntable 8 is rotatably connected to the bottom inner side of the material tank 5. Two sets of scrapers 9, which are in contact with the bottom of the material tank 5, are installed on the side of the turntable 8. A transmission rod 10 is connected to the top of the turntable 8. One end of the transmission rod 10 is connected to the output end of the first motor 11 installed on the top of the material tank 5. Multiple sets of stirring plates 12 are installed on the outer ring of the transmission rod 10. By starting the first motor 11, the first motor 11 can drive the transmission rod 10 to rotate, and the transmission rod 10 can drive the multiple sets of stirring plates 12 to rotate. Thus, under the action of the multiple sets of stirring plates 12, the material tank 5 can be mixed with the material tank 5. The chemical modifier solution is stirred, and the transmission rod 10 drives the turntable 8 to rotate. The turntable 8 drives the two sets of scrapers 9 to rotate, so that the two sets of scrapers 9 can scrape up the deposited precipitate. With the combined action of the stirring plate 12, the uniformity of the mixed solution can be effectively improved and the precipitation can be avoided. The top of the material tank 5 is provided with a feed port 6, and the side of the material tank 5 near the bottom is provided with an output pipe 7. The feed port 6 can be used to facilitate the injection of the chemical modifier solution, and the output pipe 7 can be used to facilitate the discharge of the liquid inside the material tank 5.

[0033] The vehicle body 1 has four sets of wheels 2 installed at the bottom, a traction seat 4 on one side, and a push rod 3 installed on the top of one side. The top wheels 2 facilitate the movement of the vehicle body 1, the push rod 3 facilitates the manual pushing of the device, and the traction seat 4 facilitates the movement of the device by a power equipment.

[0034] Working principle: First, by activating the electric telescopic rod 41, the electric telescopic rod 41 can drive a set of movable seats 38 to move towards the center position of the mounting frame 33. The set of movable seats 38 can drive a set of rack plates 39 to move to one side. The set of rack plates 39 can drive the second spur gear 40 to rotate. The second spur gear 40 can drive another set of rack plates 39 and another set of movable seats 38 to move in the opposite direction. Thus, the two sets of movable seats 38 can drive the two sets of connecting plates 44 to move towards the center position. The two sets of connecting plates 44 can drive the two sets of clamping plates 45 to move towards the center position and clamp and fix the spray gun 15. Then, the pump 14 can extract the chemical modifier solution inside the material barrel 5 and spray it out through the spray gun 15. Then, by activating the second motor 30, the second motor 30 can drive the rotating rod 28 to rotate. The rotating rod 28 can drive the abutment rod 27 to rotate. The abutment rod 27... The contact with the contact groove 26 causes the swing plate 25 and the rotating seat 22 to swing back and forth around the upright 21, thereby causing the sector plate 23 to rotate back and forth. The teeth 24 at one end of the sector plate 23 can drive the first spur gear 19 to rotate back and forth. The first spur gear 19 can drive the rotating shaft 17 and the base frame 18 connected to its top to rotate back and forth. The base frame 18 can drive the mounting frame 33 and the spray gun 15 mounted on its top to rotate back and forth, thereby increasing the spraying range of the spray gun 15. By starting the third motor 36, the third motor 36 can drive the worm gear 34 to rotate. The worm gear 34 can drive the turbine disk 31 to rotate. The turbine disk 31 can drive the mounting frame 33 to rotate, thereby driving the spray gun 15 mounted on its top to rotate, so as to adjust the spraying angle of the spray gun 15, thus completing the entire operation process.
