In order to quickly restore the traffic flow of the road surface after a large-scale snowfall in the city, the accumulated snow on the road surface needs to be cleaned by snow removal equipment.

[0003] At present, the accumulated snow in China is generally cleaned by a roller brush, and because the volume of the roller brush is large, the snow removal equipment and the snow sweeping roller brush are generally installed on a snow sweeper, and the hydraulic system of the snow removal equipment is driven by a power driving device on the vehicle, so as to drive the roller brush shaft of the roller brush to drive the brush sheet to perform snow sweeping work.

[0004] According to the related technology in the above, the inventor believes that the driving device on the snow sweeper drives the roller brush, which greatly changes the whole, is not convenient for the installation of the roller brush and the debugging of the whole vehicle equipment, thereby causing poor overall installation effect and difficult original vehicle recovery performance. SUMMARY

[0005] In order to reduce the change caused by the driving device of the snow sweeper to the roller brush and improve the functionality of the whole roller brush, the present application provides a mechanical self-powered snow sweeping roller brush.

The linkage structure can drive the roller brush to rotate.

[0008] By adopting the above technical scheme, the rotating shaft is driven to rotate by the engine installed on the mounting shell, and then the rotating shaft drives the speed reducer to operate, so that the speed reducer drives the roller brush to rotate through the linkage structure, thereby reducing the change caused by the driving device of the snow sweeper to the roller brush and improving the functionality of the whole roller brush.

The snap ring 57 is coaxially sleeved on the outside of the support rod 55, and the snap ring 57 is slidably connected to the support rod 55. The length of the snap groove 551 along the axis of the support rod 55 is greater than the length of the snap ring 57 along the axis of the support rod 55.

[0045] A hinged rod 58 is hingedly provided on the side wall of the protective shell 13 relative to one side of the support rod 55. The hinged connection position between the hinged rod 58 and the protective shell 13 is located at the center position of the hinged rod 58. One end of the hinged rod 58 is hingedly provided with a clamping ring 57, and the other end of the hinged rod 58 is fixedly connected to a counterweight block 59.

The inner rod 581 and the outer rod 582 are slidably connected.

[0047] When the chain 53 is loose, the counterweight 59 drives the hinge rod 58 to rotate, which in turn drives the snap ring 57 to move toward the side close to the chain 53, and then drives the support rod 55 to move toward the side close to the chain 53, and drives the third sprocket 54 located on the support rod 55 to move toward the side close to the chain 53, so that the chain 53 is tightened and engaged with the first sprocket 51 and the second sprocket 52.

[0048] The fourth sprocket 510 is meshed and connected above the chain 53, and the side of the fourth sprocket 510 facing away from the chain 53 is rotatably connected to the detection rod 5101, which is set along the direction from the rotation center of the fourth sprocket 510 to the meshing connection position between the fourth sprocket 510 and the chain 53.

[0051] A baffle 18 is fixedly connected to the sidewall of the protective shell 13 below the counterweight 59. The baffle 18 is located on the moving path of the counterweight 59. When the counterweight 59 contacts the baffle 18, the third sprocket 54 tightens the chain 53 to the safety limit. If the chain 53 is still not tightened at this time, manual adjustment is required.

[0052] When the chain 53 is loose, the spring 5103 pushes the fourth sprocket 510 to move toward the side close to the chain 53, so that the elastic force of the spring 5103 is reduced, which reduces the pressure on the pressure sensor 5102. The pressure sensor 5102 generates a signal and an alarm at the same time, controlling the hydraulic rod of the fourth hydraulic cylinder 563 to extend, driving the pressure plate 562 to move toward the side close to the support rod 55, pushing the support rod 55 to move toward the side close to the chain 53, and tightening the chain 53.

When the scraper 41 rotates, the adjustment holes 43 can align with the mounting holes 110 one by one, and the adjustment holes 43 and mounting holes 110 are then fixedly connected via pins.

[0055] The implementation principle of the mechanical self-powered snow-clearing roller brush of the embodiment of the present application is: the engine 21 drives the rotating shaft 22 to rotate, and then the rotating shaft 22 drives the input shaft of the reducer 16 to rotate, and the output shaft of the reducer 16 drives the first sprocket 51 to rotate, and the first sprocket 51 drives the chain 53 to rotate, so that the chain 53 drives the second sprocket 52 to rotate, and then the second sprocket 52 drives the roller brush 11 to rotate.

[0056] The counterweight 59 drives the hinge rod 58 to rotate, so that the hinge rod 58 drives the snap ring 57 to move toward the side close to the chain 53, and drives the third sprocket 54 to tighten the chain 53.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
