[0024] Specifically, the rotating action of the drive wheel 10 promotes the track 3 to realize the circular motion, thereby pushing the tractor to move, at the same time, the outer surface of the clamping block 9 connected with the drive wheel 10 performs the circular motion inside the defined limiting groove 6, the inner fixed bar 5 is tightly attached to the inner wall of the track 3, effectively preventing the track 3 from accidentally falling off the roller, and enhancing the stability of the walking mechanism, the fixed roller 14 is stably installed inside the circular groove 11, the diameter of the drive wheel 10 is increased, the tension of the track 3 is finely adjusted, and the track 3 is further prevented from falling off.

[0025] With reference to Figure 1 , Figure 2 and Figure 3 , the cleaning assembly comprises a water tank 16 fixedly connected to the inside of the fixed frame 2, a water inlet 17 is formed in the inside of the water tank 16, a connecting pipe 18 is fixedly connected to the inside of the water tank 16, one end of the connecting pipe 18 is fixedly connected to a fixed shell 19, the upper surface of the fixed shell 19 is fixedly connected to a motor 20, the output end of the motor 20 is fixedly connected to a rotating block 21, the outer wall of the rotating block 21 is rotatably connected to the inside of the fixed shell 19, a hard brush 22 is fixedly connected to the inside of the rotating block 21, a high-pressure water outlet 23 is arranged in the inside of the rotating block 21, a hinged seat 24 is fixedly connected to the upper surface of the fixed shell 19, a connecting rod 25 is rotatably connected to the inside of the hinged seat 24, one end of the hinged seat 24 is rotatably connected to one side of the outer wall of the fixed frame 2, a rotating rod 26 is rotatably connected to the inside of the connecting rod 25, a guide rail 27 is fixedly connected to the lower surface of the fixed frame 2, one side of the outer wall of the rotating rod 26 is slidably connected to the inner wall of the guide rail 27, a clamping block 12 is fixedly connected to the inside of the fixed frame 2, an increasing wheel 13 is arranged in the inside of the clamping block 12, a fixed roller 14 is rotatably connected to the inside of the increasing wheel 13.

[0026] Specifically, in order to solve the problem of reduced friction and slipping of the track 3 caused by yellow mud, the rotating block 21 is arranged in the fixed frame 2 and driven to rotate by the motor 20, which cooperates with the high-pressure water outlet 23 and the hard brush 22 to clean the debris on the anti-skid teeth 4, and the rotating rod 26 can adjust the angle of the rotating block 21 to ensure that the track 3 runs normally. This automatic cleaning mechanism improves the practicability and stability of the device, effectively prevents the track 3 from slipping, and saves labor and time costs.

[0027] Working principle: When a crawler tractor with a crawler walking mechanism is needed, the driving wheel 10 is first rotated to rotate the crawler 3 so that the tractor can move. At the same time, the outer wall of the block 9 connected to the rotating rod 8 is rotated inside the limiting groove 6, and the inner fixing bar 5 is connected to the inner wall of the crawler 3 to prevent the crawler 3 from slipping off the roller and limit the crawler 3, thereby improving the stability of the walking mechanism. By connecting the fixed roller 14 inside the circular groove 11, the diameter of the driving wheel 10 is increased, the tension of the crawler 3 is adjusted, and the crawler 3 is further prevented from slipping. The anti-skid teeth 4 connected to the crawler 3 can increase the friction between the crawler 3 and the ground, but the crawler 3 Frequent walking on yellow muddy ground makes it easy for debris to stick to the track 3, which reduces friction and causes the track 3 to slip. Therefore, a rotating block 21 is set inside the fixed frame 2, and the motor 20 drives the rotating block 21 to rotate. The high-pressure water outlet 23 sprays the water delivered by the connecting pipe 18, and at the same time, the hard brush 22 cleans the debris stuck on the anti-skid teeth 4, thereby improving the practicality of the device. The rotating rod 26 slides inside the guide rail 27, so that the angle of the rotating block 21 can be changed, and it can also be folded up when not in use without affecting the normal operation of the track 3. Automatic cleaning effectively improves the use effect of the track 3, saves time, and further achieves the effect of preventing the track 3 from slipping.
