[0037] The buffer member 4 is made of a combination of buffer fillers such as rubber blocks, polyurethane, and nylon.

[0038] Compared with the related art, the multi-tooth torque compensation obstacle avoidance mechanism of the sweeper provided by the utility model has the following beneficial effects:

[0039] The utility model provides a multi-tooth torque compensation obstacle avoidance mechanism for a sweeper. Now, a hollow torsion bar 1 is used as a rotating axis, a positioning component 3 is used to position a rotating roller 7 and a shell 2, and a buffer 4 is used to provide a circular elastic force for an independent shock-absorbing compensation mechanism for the sweeper. The obstacle avoidance effect is better. At the same time, the elastic mechanism is smaller in size and is lighter than an elastic mechanism with a spring as the main body. The problem that the existing spring elastic mechanism of the belt conveyor sweeper is easily corroded, insensitive, and cannot automatically avoid obstacles is effectively solved.

[0040] Second embodiment

[0041] Please refer to Figure 4 , Figure 5 and Figure 6 Based on the multi-tooth torque compensation obstacle avoidance mechanism for sweepers provided in the first embodiment of the present application, the second embodiment of the present application proposes another multi-tooth torque compensation obstacle avoidance mechanism for sweepers. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0042] Specifically, the difference of the multi-tooth torque compensation obstacle avoidance mechanism of the sweeper provided in the second embodiment of the present application is that, in the multi-tooth torque compensation obstacle avoidance mechanism of the sweeper, a sliding groove 5 is opened inside the outer shell 2, and a sliding rod 51 is slidably connected inside the sliding groove 5.

[0043] Four sliding grooves 5 are provided inside the housing 2, and sliding rods 51 are slidably connected inside the four sliding grooves 5. One end of the four sliding rods 51 is fixedly connected to one side of the mounting ring 52, so as to drive the four sliding rods 51 to move to one side when the mounting ring 52 is moved to one side.

[0044] One end of the sliding rod 51 is fixedly connected to a mounting ring 52 , and a concave handle is provided inside the mounting ring 52 .

[0045] Two concave handles are provided inside the mounting ring 52 for facilitating the movement of the mounting ring 52 to one side.

[0046] A limiting member 53 is disposed inside the mounting ring 52 . The limiting member 53 includes a limiting hole. A limiting pin is threadedly connected inside the limiting hole.

[0047] The limiting pin is a bolt, and a plurality of threaded holes adapted to the limiting pin are provided inside the mounting ring 52 and the housing 2, so as to fix the mounting ring 52 after the limiting pin is installed inside the limiting hole after the mounting ring 52 is moved to a suitable position.

[0048] A fixing hole 6 is defined inside the housing 2 , and a fixing rod 61 is slidably connected inside the fixing hole 6 .

[0049] A plurality of fixing holes 6 are provided inside the housing 2, and a fixing rod 61 is slidably connected inside each of the fixing holes 6. One side of the fixing rod 61 is arc-shaped, and one end of the sliding rod 51 is arc-shaped, so that after the arc surface of the sliding rod 51 moves to one side and contacts the arc surface of the fixing rod 61, the fixing rod 61 moves upward along the arc surface, driving the fixing pin 62 to move upward.

[0050] One end of the fixing rod 61 is fixedly connected to a fixing pin 62 , and the fixing pin 62 is tapered.

[0051] The fixing pin 62 is tapered, and is used to fix the rotating roller 7 after the fixing pin 62 penetrates into the inside of the rotating roller 7 when moving upward.

[0052] The working principle of the multi-tooth torque compensation obstacle avoidance mechanism of the sweeper provided by the utility model is as follows:

[0053] When in use, after removing the limit piece 53, move the mounting ring 52 to one side to drive the sliding rod 51 to move to one side inside the sliding groove 5 and separate, then move the rotating roller 7 to one side to drive the fixing pin 62 connected to the fixing rod 61 to move to one side in the fixing hole 6. When the fixing pin 62 is separated from the rotating roller 7, the rotating roller 7 can be removed.

[0054] After the new rotating roller 7 is put on the surface of the outer shell 2, the installation ring 52 drives the sliding rod 51 to be inserted into the interior of the sliding groove 5. When the sliding rod 51 contacts the surface of the sliding rod 51, the sliding rod 51 continues to move to one side and drives the sliding rod 51 to move to one side inside the sliding groove 5. When the sliding rod 51 moves to one side, it drives the fixing pin 62 to enter the interior of the rotating roller 7, and then the installation ring 52 can be fixed by the limit piece 53.

[0055] Compared with the related art, the multi-tooth torque compensation obstacle avoidance mechanism of the sweeper provided by the utility model has the following beneficial effects:

[0056] The utility model provides a multi-tooth torque compensation obstacle avoidance mechanism for a sweeper. After the limiter 53 is removed, the mounting ring 52 is moved to one side to drive the sliding rod 51 to move to one side to be taken out, and then the rotating roller 7 is moved to one side to drive the fixing pin 62 to automatically move to one side to separate from the rotating roller 7, thereby facilitating the replacement of the rotating roller 7 and reducing the cost of replacement.
