[0025] Furthermore, the rotating connecting rod 3 and the connecting rod 2 are both rods with adjustable lengths.

[0026] Furthermore, the connection between the adjusting rod and the central axis of the driven wheel is located between the two ends of the adjusting rod. The end of the adjusting rod 7 away from the driving wheel 51 is connected to a counterweight 10, and the counterweight 10 is centered on the connection between the central axis of the driven wheel 6 and the support frame 9. According to the principle of leverage, by replacing counterweights 10 of different weights, or connecting the counterweight 10 to the adjusting rod 7 through a connecting rod, and adjusting the length of the connecting rod, the height of the driving wheel group 5 can be adjusted, and then the contact force between the driving wheel group 5 and the conveyor belt of the belt conveyor can be adjusted to obtain power.

In the present invention, the driving wheel 51 obtains power from the conveyor belt of the belt conveyor and transmits it to the driving wheel 52. The driving wheel 52 and the driven wheel 6 transmit power through the transmission belt 4. By changing the size of the driving wheel 52 and the driven wheel 6, different reduction ratios can be obtained. The adjustment rod 7 can change the distance between the driving wheel 52 and the driven wheel 6. Since the central axis is hinged on the support frame 9, the adjustment rod 7 is connected to the central axis through the second bearing, so the adjustment rod 7 can rotate relative to the support frame 9 to change the power acquisition position, and the belt tensioner 8 is used to adjust the tightness of the belt. Since the driving wheel 51 and the active wheel 52 are coaxially fixedly connected, when the driving wheel 51 obtains power on the conveyor belt of the conveyor, the active wheel 52 will also rotate. Since the active wheel 51 and the driven wheel 6 transmit power through the transmission belt 4, when the active wheel 51 rotates, the driven wheel 6 rotates accordingly. Therefore, the driven wheel 6 can drive the rotating connecting rod 3 to rotate. By changing the length of the rotating connecting rod 3, the reciprocating distance of the dust removal broom 1 can be adjusted. The rotating pull rod 3 is connected to the dust removal broom 1 through the connecting rod 2. The dust is sent to the feed port or fixed position through the dust removal broom 1. By recovering the accumulated dust, the labor intensity of employees can be relieved, and the economic benefits and production environment can be improved.
