Specific implementation manners

[0027] The following will describe in detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0028] Embodiment 1

[0029] Since the snow-sweeping robot sweeps the snow on the road surface at a relatively fast speed, the wear of the bristles of the snow-sweeping robot due to friction with the ground is also relatively fast. In order to reduce the frequency of replacing the bristles and enable the snow-sweeping robot to work for a long time, referring to Figures 1-4 , this embodiment proposes a small snow-sweeping robot, including a vehicle body 1. A groove is provided on one side of the vehicle body 1, and a brush disk assembly 2 capable of replenishing the bristle length is installed inside the groove. During use, the vehicle body moves along the road surface, and the brush disk assembly 2 works to sweep the snow on the road surface. When the bristles are worn, control the bristles of the brush disk assembly 2 to move downward so that the bristles come into contact with the road surface again. When the bristles of the snow-sweeping robot are worn, there is no need to replace the bristles, solving the situation that the snow-sweeping brush of the existing snow-sweeping robot wears out relatively quickly and needs to be replaced frequently, and can reduce the impact of replacing the snow-sweeping brush on the snow-sweeping efficiency of the snow-sweeping robot.

[0030] In order to achieve the purpose of controlling the lowering of the bristles and keeping the bristles in contact with the road surface, in this embodiment, a brush disc assembly 2 is provided. The brush disc assembly 2 includes a bracket 21 installed at the top inside the groove. A plurality of rotating rods 22 are rotatably connected to the bottom of the bracket 21. A brush disc 23 is installed at the bottom of the rotating rod 22. A lifting disc 24 that slides along the length direction of the rotating rod 22 is installed outside the rotating rod 22. Bristles that movably penetrate the brush disc 23 are provided at the bottom of the lifting disc 24. A motor for driving the plurality of rotating rods 22 to rotate is installed at the top of the bracket 21. A lifting assembly 25 for pushing the plurality of lifting discs 24 to lift and lower is installed at the bottom of the bracket 21. During use, the motor drives the rotating rods 22 to rotate, thereby driving the brush disc 23, the lifting disc 24, and the bristles to rotate simultaneously. The bristles contact the road surface and sweep away the snow on the road surface. When the bristles are worn, the lifting assembly 25 is controlled to push the lifting disc 24 to lower, thereby driving the bristles to lower a certain distance after passing through the brush disc 23 until the bristles contact the road surface again. It is possible to control the lowering of the bristles when the bristles are worn, so that the bristles always contact the road surface, and there is no need to frequently replace the bristles, reducing the impact of replacing the bristles on the snow removal efficiency.

[0031] The bristles are made of a material with a relatively high hardness. On the one hand, it can slow down the wear speed of the bristles. On the other hand, it can also reduce the degree of the bristles bending outward during rotation, preventing the bristles from bending under the centrifugal force and unable to contact the ground.

[0032] In order to control the lowering of the bristles after the bristles are worn and keep the bristles always in contact with the road surface, in this embodiment, a lifting assembly 25 is provided. The lifting assembly 25 includes a cylinder 251 installed at the bottom of the bracket 21. A wear-resistant frame 252 that slides with the lifting disc 24 is installed at the output end of the cylinder 251. A plurality of elastic plates 253 are fixedly connected between the brush disc 23 and the lifting disc 24. During use, the elastic plates 253 push the lifting disc 24 to rise to the highest position. When it is necessary to control the lowering of the bristles after the bristles are worn, the cylinder 251 extends, pushing the wear-resistant frame 252 to lower, and then pushing the lifting disc 24 to lower, so that the bristles at the bottom of the lifting disc 24 pass through the brush disc 23 and then lower to contact the road surface again. The wear-resistant frame 252 rubs against the rotating lifting disc 24, and it is possible to control the lowering of the bristles as needed, so that the bristles always contact the road surface, and at the same time, the friction degree between the bristles and the road surface can be controlled.

[0033] Since the cleaning requirements for snow of different thicknesses are different, it is necessary to improve the cleaning ability of snow when the snow is thick. This requires increasing the friction between the brush bristles and the road surface. In this embodiment, a structure for adjusting the friction degree between the brush bristles and the road surface is provided. The rotating rod 22 movably penetrates through the brush disc 23. A circular tube 3 sleeved outside the rotating rod 22 is fixedly connected to the top of the brush disc 23. A plurality of bolts 4 movably penetrating through the circular tube 3 are arranged on the outer side of the circular tube 3. During use, the circular tube 3 is moved downward along the rotating rod 22 to lower the brush disc 23. The brush disc 23 drives the lifting disc 24 to descend through the elastic plate 253, thereby lowering the brush bristles. The length of the contact between the brush bristles and the road surface increases, the length of the brush bristles being squeezed and bent on the road surface increases, the squeezing force of the brush bristles on the road surface increases, and thus the cleaning force of the brush bristles on the snow on the road surface increases. Then, the bolt 4 is rotated to fix the circular tube 3 on the rotating rod 22, and the length of the contact between the brush bristles and the road surface can be adjusted as needed, and the squeezing force between the brush bristles and the road surface can be controlled, which is convenient for increasing the cleaning force of the snow on the road surface and improving the cleaning ability of the snow on the road surface.

[0034] Embodiment 2

[0035] The cleaning ability of a single brush disc 23 for the road surface is limited. In order to improve the cleaning ability of the snow on the road surface in multiple ways, referring to Figures 1-7 , on the basis of Embodiment 1, this embodiment provides a structure for blowing air on the snow on the road surface. A sealed box 5 is installed inside the groove. A jet frame 6 is communicated with the bottom of the sealed box 5. A delivery pipe 7 for ventilating the inside thereof is communicated with the top of the sealed box 5. One side of the inner wall of the groove is fixedly connected with a limiting rod 8. A transverse groove is opened on one side of the sealed box 5 close to the limiting rod 8. The limiting rod 8 movably extends into the transverse groove. A threaded rod 9 with one end movably extending into the sealed box 5 is arranged on the side of the groove away from the limiting rod 8. A control groove is opened on the top of the vehicle body 1. An air pump 10 and a wifi module are installed on the inner bottom of the control groove. Both the air cylinder 251 and the delivery pipe 7 are communicated with the air outlet end of the air pump 10. The air outlet end of the air pump 10 is communicated with a water separator 11. Solenoid valves are installed on each branch pipe of the water separator 11. Both the air cylinder 251 and the delivery pipe 7 are communicated with one of the branch pipes of the water separator 11. During use, the wifi module facilitates the user to connect to the software to control the operation of the snow cleaning robot. The air pump 10 sends air into the air cylinder 251 and the delivery pipe 7 through the water separator 11, and then sprays out from the jet frame 6 through the delivery pipe 7 and the sealed box 5. The sealed box 5 can be rotated along the threaded rod 9 as needed to make the jet frame 6 blow air in different directions. The snow on the road surface can be blown away by blowing air, which cooperates with the cleaning of the snow on the road surface by the brush disc 23 and improves the ability to clean the snow on the road surface.

[0036] To protect the air pump 10 and the wifi module, a cover plate 12 is rotatably connected to the top of the vehicle body 1. An air inlet pipe 13 penetrating the cover plate 12 is installed on the top of the cover plate 12. One end of a hose 14 communicating with the air inlet end of the air pump 10 extends into the interior of the air inlet pipe 13. The hose 14 at the air inlet end of the air pump 10 is connected to the air inlet pipe 13, enabling the air pump 10 to draw the air outside the vehicle body 1 into the air pump, and at the same time, the opening and closing process of the cover plate 12 does not affect the air intake of the air pump 10.
