[0023] Please refer to Figures 1-4, A belt conveyor deviation adjusting device, including a conveyor belt 1. At the bottom of the front side and the rear side of the conveyor belt 1, a limit structure 2 distributed in an array is fixedly connected. On the left side and the rear side inside the conveyor belt 1, a main roller 4 is rotatably arranged. Inside the conveyor belt 1, a roller 5 distributed in an array is rotatably arranged. At both ends of the main roller 4, a first driving rod 401 distributed in a circular array is fixedly connected. At both ends of the roller 5, a second driving rod 501 distributed in a circular array is fixedly connected. The first driving rod 401 and the second driving rod 501 are both engaged and adapted with the limit structure 2. The mutual fixing and traction effects between the limit structure 2 and the first driving rod 401 and the second driving rod 501 can prevent the conveyor belt 1 from running off track. On the front and back sides of the main roller 4, a connecting rod 3 is provided. Inside the inner wall of the connecting rod 3, auxiliary rods 301 distributed in an array are fixedly connected. One end of the connecting rod 3 and the auxiliary rod 301 are both arranged at the axis centers of the main roller 4 and the roller 5, so that the main roller 4 and the roller 5 can support and rotate, facilitating the driving work of the conveyor belt 1. On the outer wall of the connecting rod 3, a partition 6 is fixedly connected. Inside the inner wall of the partition 6, receiving blocks 11 distributed symmetrically are fixedly connected. A pressing rod 1201 is slidably arranged on the receiving block 11. At the top of the pressing rod 1201, a pressing plate 12 is fixedly connected. An adaptation groove is opened in the pressing plate 12, and the adaptation groove is in contact and adaptation with the limit structure 2.

[0024] Please refer to Figure 1 , The limit structure 2 includes a connecting block 201, a buckle 202 and a pushing block 203. The connecting block 201 is fixedly connected to the bottom of the conveyor belt 1. On the outer wall of the connecting block 201, a buckle 202 is fixedly connected. The buckle 202 is engaged and adapted with the first driving rod 401 and the second driving rod 501. On one side of the buckle 202, a pushing block 203 is fixedly connected. The buckle 202 is engaged with the first driving rod 401 and the second driving rod 501. The mutual fixing and traction effects between the buckle 202 and the first driving rod 401 and the second driving rod 501 can prevent the conveyor belt 1 from running off track. The pushing block 203 is adapted to the adaptation groove, so as to facilitate the extrusion of the pressing plate 12, so that the pressing plate 12 can rebound to re-clamp the buckle 202 at the bottom of the conveyor belt 1 on the second driving rod 501.

[0025] Please refer to Figure 4, the pushing block 203 is specifically trapezoidal and is adapted to the fitting groove. A first sliding rod 14 and a second sliding rod 18 are fixedly connected between the receiving blocks 11. The second sliding rod 18 is directly below the first sliding rod 14. A connecting block 1202 is fixedly connected to the center of the bottom of the pressing plate 12. Symmetrically distributed movable rods 13 are rotatably arranged on the connecting block 1202. One end of the movable rod 13 is fixedly connected to a first slider 16. The first slider 16 is slidably arranged on the first sliding rod 14. A second slider 17 is fixedly connected to the bottom of the first slider 16. The second slider 17 is slidably arranged on the second sliding rod 18. After the pressing plate 12 receives the force transmitted by the pushing block 203, it is pressed down. After being pressed down, the connecting block 1202 drives the movable rods 13 to squeeze the first slider 16 and the second slider 17 to both sides, so that the first slider 16 and the second slider 17 slide on the first sliding rod 14 and the second sliding rod 18.

[0026] Please refer to Figure 4 , compression springs 15 are sleeved on the first sliding rod 14 and are symmetrically distributed. One end of the compression spring 15 is in contact with the outer wall of the first slider 16. The first slider 16 squeezes the compression spring 15 while sliding. Subsequently, the first slider 16 is reset and slides back to its original position through the resilience of the compression spring 15, so that the pressing plate 12 pushes the pushing block 203 back again, resets the conveyor belt 1 to its original position and completes the deviation adjustment work.

[0027] Please refer to Figure 2 and Figure 3 , symmetrically distributed legs 7 are fixedly connected to the outer wall of the connecting rod 3. A support plate 8 is fixedly connected to one of the legs 7. A motor box 9 is fixedly connected to the support plate 8. A motor is arranged in the motor box 9. The output end of the motor is connected to the axis of one of the main rollers 4. A cleaning structure 10 is fixedly connected to the other leg 7. The cleaning structure 10 includes an ash accumulation box 1001 and a brush 1002. The ash accumulation box 1001 is fixedly connected to the inner wall of the leg 7. The brush 1002 is arranged on the top of the ash accumulation box 1001, and its end is in contact with the outer wall of the conveyor belt 1. The leg 7 is used to support the overall structure. The motor in the motor box 9 is connected to the axis of one of the main rollers 4, so as to drive the main roller 4 to rotate and make the conveyor belt 1 operate normally. The cleaning structure 10 arranged on the other leg 7 contacts the outer wall of the conveyor belt 1 through the brush 1002 on the top of the ash accumulation box 1001, so that the conveyor belt 1 sweeps off the dust and sundries adhered after each transportation, and makes the dust and sundries fall into the ash accumulation box 1001, thus completing the cleaning of the surface of the conveyor belt 1.

[0028] The specific operation process of this utility model is as follows: The motor in the motor box 9 starts, and its output end is connected to the axis of one of the main rollers 4, thereby driving the main roller 4 to rotate. Since there are multiple belt rollers 5 and the main rollers 4 on the left and right sides in the conveyor belt 1, these rollers are clamped with the buckle 202 of the limit structure 2 through the first driving rod 401 and the second driving rod 501. Therefore, when the main roller 4 rotates, it will drive the entire conveyor belt 1 and other rollers to rotate synchronously, realizing the normal operation of the conveyor belt 1. While the conveyor belt 1 is running, the cleaning structure 10 fixed on the other leg 7 starts to work. The brush 1002 in the cleaning structure 10 contacts the outer wall surface of the conveyor belt 1. As the conveyor belt 1 moves, the brush 1002 continuously sweeps the dust and sundries on the surface of the conveyor belt 1 and sweeps these sundries into the dust collection box 1001, thereby keeping the surface of the conveyor belt 1 clean. When the conveyor belt 1 runs off track during operation, the contact position between the buckle 202 in the limit structure 2 and the first driving rod 401 or the second driving rod 501 will shift. At this time, the push block 203 will contact the fitting groove in the pressing plate 12 and apply a thrust to the pressing plate 12. After being subjected to the force of the push block 203, the pressing plate 12 contracts and moves, and at the same time drives the connecting block 1202 and the movable rod 13 connected thereto to move to both sides. The other end of the movable rod 13 is connected to the first slider 16. The first slider 16 slides on the first slide rod 14 and drives the second slider 17 to slide synchronously on the second slide rod 18. During this process, the first slider 16 will compress the compression spring 15. When the pressing plate 12 is pressed down to a certain extent, the conveyor belt 1 will receive the reaction force of the compression spring 15 rebounding, causing the buckle 202 at its bottom to be re-clamped with the second driving rod 501, realizing the deviation adjustment of the conveyor belt 1. At this time, due to the resilience of the compression spring 15, the first slider 16 and the second slider 17 will slide back to their original positions along the first slide rod 14 and the second slide rod 18, thereby driving the pressing plate 12 to reset. Subsequently, the push block 203 disengages from the fitting groove. After the above deviation adjustment process, the conveyor belt 1 returns to the correct position and maintains stable operation. At the same time, the cleaning structure 10 continues to clean the surface of the conveyor belt 1 to ensure the cleanliness and smoothness of the conveyor belt 1 during transportation.

[0029] The above combines the accompanying drawings to make an exemplary description of the present utility model. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
