Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of snow removal equipment, in particular to a rear-mounted snow removal roller brush and snow removal equipment. BACKGROUND

[0002] In order to remove the snow on the road surface and ensure the safety of vehicles and pedestrians, snow removal equipment is usually used to clean the accumulated snow on the road surface. The snow removal roller brush is an important component of the snow removal equipment. The snow removal roller brush is driven to rotate by a motor, so that the bristles contact the ground, thereby achieving the purpose of cleaning the accumulated snow.

[0003] In the existing snow removal equipment, the snow removal roller brush is usually mounted in front of the snow removal equipment or between the front and rear wheels. When the amount of accumulated snow is small, the cleaning effect can be ensured. However, when the amount of accumulated snow is large, the cleaning effect is not good. The residual snow on the road surface is crushed by the rear wheels of the snow removal equipment, and then freezes as the temperature decreases, which can easily cause traffic accidents. SUMMARY

[0004] Based on the above problems, the present application provides a rear-mounted snow removal roller brush and snow removal equipment. The snow removal roller brush is detachably mounted behind the rear wheels of the vehicle, and can clean the snow crushed by the rear wheels of the vehicle and the residual snow.

The snow removal roller brush comprises a roller brush body, a connecting rod, an oscillating oil cylinder and a supporting wheel. The connecting rod is connected to the roller brush body through a lifting oil cylinder. The lifting oil cylinder can control the lifting or lowering of the roller brush body through extension and contraction. One end of the oscillating oil cylinder is connected to the connecting frame, and the other end of the oscillating oil cylinder is connected to the roller brush body. The oscillating oil cylinder can control the oscillation of the two sides of the roller brush body through extension and contraction. The supporting wheel is connected to the roller brush body and used to drive the roller brush body to walk together with the vehicle.

[0007] Preferably, an arc-shaped cover plate is mounted at the top of the roller brush body. The cover plate is provided with a connecting hole for corresponding connection with one end of the connecting rod. The other end of the connecting rod is connected to the connecting frame.

[0008] Preferably, the connecting frame has a U-shaped structure, comprising a horizontally arranged connecting beam and side connecting parts located on both sides of the connecting beam. The side connecting parts are connected to the main beam through fasteners, and the connecting beam is connected to the connecting rod through fasteners.

[0009] Preferably, the supporting wheel is two, and the supporting wheels are arranged at the rear end of the roller brush body along the length direction of the roller brush body.

[0010] Preferably, the upper end of the connecting frame is connected to the main beam of the vehicle chassis and is arranged at the rear end of the rear wheels of the vehicle.

[0011] The second aspect of the present application provides a snow removing device. Comprising: the rear snow removing roller brush of any one of the above, the rear snow removing roller brush is connected with the main beam of the vehicle chassis through the connecting frame.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] The rear snow removing roller brush of the present application is connected with the main beam through the connecting frame, so that the entire snow removing roller brush is installed on the main beam behind the rear wheels of the vehicle, and the snow crushed by the rear wheels of the vehicle and the residual snow can be cleaned. During normal driving of the vehicle, the roller brush body can be lifted upward by the lifting oil cylinder; when it is necessary to clean the snow on the road surface, the roller brush body can be swung downward by the lifting oil cylinder to form contact with the road surface, so that the ice and snow road surface is cleaned by the roller brush blades on the roller brush body. At the same time, during the cleaning of the snow on the road surface by the roller brush body, the swing angle of the roller brush body in the horizontal plane can be adjusted by the swing oil cylinder arranged between the connecting frame and the side of the roller brush body, so as to improve the cleaning efficiency of the snow on the road surface.

[0021] As described above, the existing snow-removing roller brushes are usually installed at the front of the snow-removing device or in the middle of the vehicle. When there is too much snow, there will be residual snow on the road and snow on the vehicle tracks, which will affect the driving of the vehicle and the traffic safety.

[0022] To solve the above problems, the embodiment of the present application provides a rear-mounted snow-removing roller brush, which is installed on the main beam behind the rear wheels of the vehicle and can clean the snow rolled by the rear wheels of the vehicle and the residual snow. In addition, the snow-removing roller brush can swing left and right by 30°, which can not only clean the residual snow but also sweep the snow rolled by the wheels to the outside of the road, so that the cleaned road is cleaner.

[0023] Referring to Figures 1 to 4 The embodiment of the present application provides a rear-mounted snow-removing roller brush, which is detachably installed at the rear end of the rear wheels of the vehicle through the connecting frame 2 and the main beam 8, and is used for cleaning the snow rolled by the rear wheels 9 of the vehicle during driving and the residual snow.
