Description

Technical Field

[0001] The present invention relates to the technical field of road sweeping, in particular to a sweeping device and a vehicle. Background Art

[0002] Road cleaning can include snow removal, garbage disposal, etc. For example, manual snow removal, snow melting and snow removal, and mechanical snow removal can be performed. Since manual snow removal requires relatively more manpower and snow melting and snow removal can cause environmental pollution, mechanical snow removal is usually used to deal with snow accumulation. Mechanical snow removal can be achieved by using sweeping equipment.

[0003] The sweeping brush device usually includes a roller brush, auxiliary wheels and a handle-driven adjusting screw. The auxiliary wheels are used to support the sweeping brush device. The height of the roller brush from the ground can be changed by adjusting the handle-driven adjusting screw.

[0004] However, since the handle needs to be manually operated to drive the adjusting screw to change the height of the roller brush from the ground, the known sweeping brush device at least consumes relatively more human resources. Summary of the invention

[0005] The present disclosure provides a sweeping brush device and a vehicle including the sweeping brush device. The sweeping brush device can use a hydraulic cylinder to provide power to a piston rod, and change the height of a roller brush from the ground by extending and retracting the piston rod, thereby reducing human resource consumption and bringing convenience to installation and disassembly.

[0006] To achieve the above-mentioned objectives, the first aspect of the present disclosure provides a sweeping brush device, which includes: a device body; a roller brush connected to the device body; a hydraulic cylinder connected to the device body, provided with a piston rod, and used to provide power for the extension and retraction of the piston rod; an auxiliary wheel connected to the piston rod through a bracket, and used to change the height of the roller brush from the ground as the piston rod is extended and retracted.

[0007] A second aspect of the present disclosure provides a vehicle, comprising the sweeping and brushing device of the first aspect or its various implementations.

[0008] In the above implementation of the present disclosure, the equipment body of the sweeping and brushing equipment is connected with a roller brush and a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the auxiliary wheel through a bracket, and the auxiliary wheel can be used to support the equipment body; the hydraulic cylinder can extend and retract the piston rod, thereby changing the height of the equipment body from the ground, and then changing the height of the roller brush from the ground. Since there is no need to manually operate the handle to drive the adjustment screw, human resource consumption can be reduced. In addition, compared with manual operation, driving the piston rod through the hydraulic cylinder can realize the extension and retraction of the piston rod more timely, which accordingly improves efficiency and brings convenience to installation and disassembly.

DETAILED DESCRIPTION

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In this disclosure, for the convenience of description, the directional words such as "upper" and "lower" used generally refer to the "upper" and "lower" of the corresponding components when they are in use, and the vertical direction is perpendicular to the horizontal direction. Figure 5 For example, the position of the hydraulic cylinder 130 relative to the auxiliary wheel 140 can be defined as "up". In addition, the directional words "inside" and "outside" used are "inside" and "outside" relative to the corresponding component's own contour. In addition, the terms "first", "second", etc. used in this application are to distinguish one element from another, and do not have order and importance. In the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0020] For known sweeping and brushing equipment and vehicles, the sweeping and brushing equipment generally includes an equipment body, a roller brush and auxiliary wheels; the roller brush and the auxiliary wheels are respectively connected to the equipment body, and the auxiliary wheels are used to support the equipment body. The height of the equipment body from the ground can be adjusted by adjusting the distance between the auxiliary wheels and the equipment body, thereby adjusting the height of the roller brush connected to the equipment body from the ground. However, the distance between the auxiliary wheels and the equipment body is generally adjusted manually, which consumes a lot of human resources. In addition, manual operation also has the disadvantages of low efficiency, long time consumption, poor accuracy, etc.

[0021] In order to at least solve the above-mentioned defects, the present disclosure provides a sweeping and brushing device and a vehicle including the sweeping and brushing device. In order to facilitate understanding of the present application, the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 7 The embodiment of the present application provides a sweeping brush device 100, which includes: a device body 110; a roller brush 120, which is connected to the device body 110; a hydraulic cylinder 130, which is connected to the device body 110 and is provided with a piston rod 131, and is used to provide power for the extension and retraction of the piston rod 131; an auxiliary wheel 140, which is connected to the piston rod 131 through a bracket 150, and is used to change the height of the roller brush 120 from the ground as the piston rod 131 is extended and retracted.

[0023] It should be noted that the roller brush 120 can handle snow, water, garbage, etc. by rotating. The device body 110 can provide power for the rotation of the roller brush 120. The distance between the device body 110 and the rotation axis of the roller brush 120 can be fixed. In this case, the height of the roller brush 120 from the ground can be changed by changing the height of the device body 110 from the ground. The height of the roller brush 120 from the ground can be measured by the height of the rotation axis of the roller brush 120 from the ground. By changing the height of the roller brush 120 from the ground, the width of the bristles of the roller brush 120 touching the ground can also be changed, and it can also provide convenience for the installation, maintenance, and disassembly of the roller brush 120.

[0024] It should be further explained that one end of the piston rod 131 can be extended into the hydraulic cylinder 130, and the other end of the piston rod 131 can be connected to the auxiliary wheel 140. The pressure in the hydraulic cylinder 130 can be adjusted by hydraulic oil, and when the pressure in the hydraulic cylinder 130 changes, the piston rod 131 performs telescopic movement. Since the height of the roller brush 120 from the ground can be adjusted by using the cooperation of the hydraulic cylinder 130 and the piston rod 131, human resources can be saved compared with manual adjustment. In addition, the telescopic movement of the piston rod 131 is achieved by adjusting the hydraulic cylinder 130. Compared with manual operation, the present invention has the advantages of high efficiency, short time consumption, high accuracy, etc.

By providing the auxiliary wheel bracket 151, the force generated by the extension and contraction of the piston rod 131 can be transmitted to the rotating shaft 141, and accordingly, the relative distance between the hydraulic cylinder 130 and the rotating shaft 141 is changed, and the relative distance between the equipment body 110 and the rotating shaft 141 is changed, which provides convenience for adjusting the height of the roller brush 120 from the ground.
