[0025] Please see Figure 3The adjusting conveyor structure 3 includes two protective plates 31. The front protective plate 31 has a circular through-hole 32 extending to the rear. A rotating shaft 33 is movably connected to the inner wall of the circular through-hole 32. A rotating roller 34 is fixedly connected to the rear end of the rotating shaft 33.

A second rotating roller 37 is fitted onto the other end of the inner wall of the conveyor belt 35. The front and rear ends of the second rotating roller 37 are connected to... Two protective plates 31 are rotatably connected on their sides that are close to each other. Limiting discs 38 are fixedly connected to the right side of the two protective plates 31 on their sides that are far apart from each other. Support sleeves 39 are movably connected to the outer walls of the limiting discs 38. Feed guide plates 30 are fixedly connected to the lower sides of the two support sleeves 39 on their sides that are close to each other. A drive motor 301 is fixedly connected to the front end of the rotating shaft 33. A motor housing 302 is provided on the outer wall of the drive motor 301. The rear side of the motor housing 302 is fixedly connected to the front side of the front protective plate 31. The top left side of the two protective plates 31... A bucket 303 is fixedly connected. A fixing plate 304 is fixedly connected to the bottom of two protective plates 31. A mounting groove 305 is provided at the bottom of the fixing plate 304.

The bottom of the fixed seat 312 is fixedly connected to the top of the moving frame 1. By starting the stepper motor 308, the rotating shaft 307 is rotated, which in turn drives the threaded rod 309 to rotate. When the threaded rod 309 rotates, it drives the slider 310 to move within its outer wall and the mounting groove 305. The movement of slider 310 further drives the bucket 303 and conveyor belt 35 to tilt via connecting plate 311, realizing the scooping of soil and the resetting and lifting of the device. When soil repair is required, stepper motor 308 is started to adjust the angle of bucket 303 according to different terrain and soil conditions. Then, bucket 303 is driven into the ground and the vehicle body is driven to walk on the ground to be repaired. At the same time, drive motor 301 is started, driving shaft 33 and roller 34 to rotate. The conveyor belt 35 on roller 34 rotates accordingly. The separator plate 36 on conveyor belt 35 will drive the soil to move, ensuring that the soil will not scatter during the transportation process. Then, the soil will pass through feed guide plate 30 and screening structure 4 in sequence into crushing mechanism 2 for repair.

Rectangular through holes 406 penetrating into the interior of the rectangular tank 42 are provided on the right side of the inner walls of the two rectangular feed holes 404 on opposite sides. A motor housing 43 is fixedly connected to the left side of the front rectangular tank 42. A circular movable hole 44 penetrating into the interior of the motor housing 43 is provided on the left side of the inner wall of the front rectangular tank 42. A rotating shaft 44 is movably connected to the inner wall of the circular movable hole 43. A stepper motor is fixedly connected to the left end of the rotating shaft 44. A lead screw 46 is fixedly connected to the right end of the rotating shaft 44 (machine 2 45). A slider 47 is threadedly connected to the outer wall of the lead screw 46. Slide rods 48 are fixedly connected to the left and right sides of the inner wall of the rear rectangular groove 42. Slide sleeves 49 are movably connected to the outer wall of the slide rods 48. Connecting blocks 40 are fixedly connected to the sides of the slider 47 and slide sleeves 49 that are close to each other. The outer wall of the connecting blocks 40 is movably connected to the inner wall of the rectangular through hole 406. A moving frame 402 is fixedly connected to the sides of the two connecting blocks 40 that are close to each other. The outer wall of the moving frame 402 is movably connected to the inner wall of the two guide grooves 401. Multiple electromagnetic plates 403 are fixedly connected in a horizontal array on the front and rear sides of the inner wall of the moving frame 402. A receiver is fixedly connected to the bottom right side of the fixed groove 41. The receiving trough 405 has a rectangular hole extending through it on its right side. A movable door 407 is hinged to the inner wall of the rectangular hole. The bottom of the receiving trough 405 is fixedly connected to the top of the movable frame 1. The bottom left side of the fixed trough 41 is fixedly connected to the top of the crushing mechanism 2, and the top left side of the fixed trough 41 is fixedly connected to the bottom of the feed guide plate 30. First, the electromagnetic plate 403 is activated. When soil enters the movable frame 402 through the feed guide plate 30 and the rectangular feed through-hole 404, the electromagnetic plate 403 adsorbs metallic impurities in the soil, ensuring that the impurities do not enter the subsequent remediation process. After screening, the stepper motor 45 is activated, driving the rotating shaft 44 and the lead screw 46 to rotate. The rotation of the lead screw 46 drives the slider 47 to move on the outer wall of the lead screw 46. At the same time, it drives the front connecting block 40 to move the moving frame 402 in the guide groove 401, and drives the rear connecting block 40 to slide the sliding sleeve 49 on the outer wall of the sliding rod 48. The movement of the connecting block 40 in the rectangular through hole 406 and the sliding sleeve 49 on the outer wall of the sliding rod 48 maintain the stability of the moving frame 402. When the moving frame 402 moves above the storage groove 405, the electromagnetic plate 403 is turned off to collect the metal impurities in the moving frame 402. Then the movable door 407 is opened to clean the collected impurities. The screened soil will enter the crushing mechanism 2 for further repair processing.

[0027] Working principle:

[0028] By activating stepper motor 308, rotating shaft 307 is driven to rotate, which in turn drives threaded rod 309 to rotate. When threaded rod 309 rotates, it drives slider 310 to move within its outer wall and mounting groove 305. The movement of slider 310 further drives bucket 303 and conveyor belt 35 to tilt via connecting plate 311, realizing soil scooping and device resetting and lifting. When soil repair is required, stepper motor 308 is activated to adjust the angle of bucket 303 according to different terrain and soil conditions. Then, bucket 303 is driven into the ground, and the vehicle body moves on the ground to be repaired. At the same time, drive motor 301 is activated, driving rotating shaft 33 and rotating roller 34 to rotate. The conveyor belt 35 on the rotating roller 34 rotates accordingly. The separator plate 36 on the conveyor belt 35 will move the soil to ensure that the soil does not scatter during the conveying process. The soil will then pass through feeding guide plate 30 and screening structure 4 into crushing mechanism 2 for repair.

[0029] First, the electromagnetic plate 403 is activated. When soil enters the moving frame 402 through the feed guide plate 30 and rectangular feed through-hole 404, the electromagnetic plate 403 adsorbs metallic impurities in the soil, ensuring that the impurities do not enter the subsequent remediation process. After screening, the stepper motor 45 is activated, driving the rotating shaft 44 and lead screw 46 to rotate. The rotation of the lead screw 46 drives the slider 47 to move on the outer wall of the lead screw 46. At the same time, it drives the front connecting block 40, causing the moving frame 402 to move within the guide groove 401. The moving frame 402 moves and drives the connecting block 40 behind it to slide the sliding sleeve 49 on the outer wall of the sliding rod 48. The stability of the moving frame 402 is maintained by the movement of the connecting block 40 in the rectangular through hole 406 and the sliding sleeve 49 on the outer wall of the sliding rod 48. When the moving frame 402 moves above the storage slot 405, the electromagnetic plate 403 is turned off to collect the metal impurities in the moving frame 402. Then the movable door 407 is opened to clean the collected impurities. The screened soil will enter the crushing mechanism 2 for further repair processing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
