[0002] In terms of its meaning, a road is an infrastructure for various trackless vehicles and pedestrians to pass through; according to its usage characteristics, it is divided into highways, urban roads, rural roads, factory roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages, and school roads, etc. After a road has been used for a period of time, it needs to be cleaned.

[0003] Currently, a road sweeping device is needed for road cleaning, but the current road cleaning device still has the following problems in use:

[0004] Currently, most road cleaning devices clean the ground through the rotating brushes at the bottom, and then suck up the garbage through a vacuum cleaner. However, the position of the rotating round brush is fixed, and its cleaning width is not easy to adjust, so the practicability is not good. Content of the Utility Model

[0005] The purpose of the utility model aims to solve at least one of the above technical defects.

[0006] Therefore, an object of the utility model is to provide a road cleaning device to solve the problems mentioned in the background technique and overcome the deficiencies existing in the prior art.

[0007] To achieve the above object, an embodiment of one aspect of the utility model provides a road cleaning device, including a vehicle board. At both corners of one side edge of the bottom surface of the vehicle board, there are rotatably connected connecting shaft sleeves. The bottom of the connecting shaft sleeve is fixedly connected with a roller frame. At the centers of both sides of the inner wall of the roller frame, there are rotatably connected driving rollers. A driving belt is commonly connected to the outer surfaces of the two driving rollers. At the bottom of the outer wall of the driving belt, there are fixedly connected a number of bristles, and all the bristles are perpendicular to the ground. The top of the connecting shaft sleeve penetrates through the top surface of the vehicle board. On one side of the outer wall of the connecting shaft sleeve located on the top surface of the vehicle board, there is fixedly connected a driven worm gear. At the center of the edge of one side surface of the top surface of the vehicle board close to the connecting shaft sleeve, there is fixedly connected a double-output motor. Both output ends of the double-output motor are fixedly connected with driving worm gears. The two driving worm gears are respectively meshed with the two driven worm gears. At the positions corresponding to the driving worm gears on both sides of the vehicle board, there are fixedly connected connecting ears. The ends of the two driving worm gears far from the double-output motor are respectively rotatably connected with the two connecting ears. At the edge of one side of the top surface of the vehicle board close to the connecting shaft sleeve, there is fixedly connected a support frame. At the edges of both sides of the top surface of the support frame, there are fixedly connected driving motors. The two driving motors are respectively fixedly connected through the two connecting shaft sleeves to the centers of the tops of the roller frame and the driving rollers.

[0008] Preferably, according to any of the above solutions, universal wheels are fixedly connected to both sides of the bottom surface of the vehicle board. A push handle is fixedly connected to the edge of one side of the top surface of the vehicle board away from the support frame. The bottoms of several bristles protrude from the bottoms of the universal wheels.

[0009] The technical effect achieved by adopting the above solution is that it is convenient to push and move flexibly through the push handle and the universal wheels, and at the same time, the bristles can be pressed tightly against the ground to improve the cleaning effect.

[0012] Preferably, according to any of the above solutions, the sewage suction cover is located between two roller frames. The length of the inlet of the sewage suction cover is adapted to the distance between the two roller frames. The position of the edge of the bottom of the sewage suction cover corresponds to the position of the bottom of the universal wheels.

[0013] The technical effect achieved by adopting the above solution is that by intercepting the sewage suction cover between the two roller frames, the swept garbage can be swept towards the middle and then smoothly sucked away by the sewage suction cover, thus forming a relatively large cleaning width.

[0014] Preferably, according to any of the above solutions, the two roller frames are symmetrically arranged with the center line of the vehicle board as the axis of symmetry. The distribution range of several bristles is adapted to the size range of the bottom surface of the transmission belt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present invention with reference to the drawings, but the protection scope of the present invention is not limited to the following.

[0024] Embodiment 1: As Figures 1 to 3 shown, a road cleaning device includes a vehicle board 1. At the two corners of one side edge of the bottom surface of the vehicle board 1, there are rotatably connected connecting bushings 2. The bottom of the connecting bushing 2 is fixedly connected with a roller frame 3. At the centers of both sides of the inner wall of the roller frame 3, there are rotatably connected transmission rollers 17. The outer surfaces of the two transmission rollers 17 are jointly connected with a transmission belt 4. At the bottom of the outer wall of the transmission belt 4, there are fixedly connected a number of brush bristles 5. A number of brush bristles 5 are all perpendicular to the ground. The top of the connecting bushing 2 penetrates through the top surface of the vehicle board 1. On one side of the outer wall of the connecting bushing 2 at the top surface of the vehicle board 1, there is fixedly connected a driven worm gear 6. At the center of one side edge of the top surface of the vehicle board 1 close to the connecting bushing 2, there is fixedly connected a double-output motor 7. Both output ends of the double-output motor 7 are fixedly connected with driving worms 8. The two driving worms 8 are respectively meshed with the two driven worm gears 6. At the positions corresponding to the driving worms 8 on both sides of the vehicle board 1, there are fixedly connected connecting ears 9. The ends of the two driving worms 8 far away from the double-output motor 7 are respectively rotatably connected with the two connecting ears 9. At the edge of one side of the top surface of the vehicle board 1 close to the connecting bushing 2, there is fixedly connected a support frame 10. At the edges of both sides of the top surface of the support frame 10, there are fixedly connected driving motors 11. The two driving motors 11 are respectively fixedly connected through the two connecting bushings 2 to the centers of the tops of the roller frame 3 and the transmission roller 17.

[0025] As an alternative technical solution of the present utility model, universal wheels 15 are fixedly connected to both sides of the bottom surface of the vehicle board 1. A push handle 16 is fixedly connected to the edge of one side of the top surface of the vehicle board 1 away from the support frame 10. The bottoms of several bristles 5 protrude from the bottoms of the universal wheels 15. By means of the push handle 16 and the universal wheels 15, it is convenient to push and move flexibly, and at the same time, the bristles 5 can be pressed against the ground to improve the cleaning effect.

[0026] As an alternative technical solution of the present utility model, an industrial vacuum cleaner 13 is fixedly connected to the middle of one side of the top surface of the vehicle board 1. A sewage suction cover 12 is fixedly connected to one side of the bottom surface of the vehicle board 1. A suction pipe 14 is fixedly connected to the suction end fixing rod of the industrial vacuum cleaner 13. One end of the suction pipe 14 away from the industrial vacuum cleaner 13 is fixedly connected to the top of the sewage suction cover 12 and communicates with the top of the inner wall of the sewage suction cover 12. Through the industrial vacuum cleaner 13 and the sewage suction cover 12, the garbage converged in the middle during cleaning can be completely sucked away.

[0027] As an alternative technical solution of the present utility model, the sewage suction cover 12 is located between the two roller frames 3. The inlet length of the sewage suction cover 12 is adapted to the distance between the two roller frames 3. The position of the edge of the bottom of the sewage suction cover 12 corresponds to the position of the bottom of the universal wheels 15. By intercepting between the two roller frames 3 through the sewage suction cover 12, the garbage swept to the middle during cleaning can be sucked away by the sewage suction cover 12 along the trend, thus forming a larger cleaning width.

[0028] As an alternative technical solution of the present utility model, the two roller frames 3 are symmetrically arranged with the center line of the vehicle board 1 as the axis of symmetry. The distribution range of several bristles 5 is adapted to the size range of the bottom surface of the transmission belt 4, so that the two roller frames 3 are symmetrically opened in a V shape, and the garbage swept is converged to the middle.

[0029] A road cleaning device has the following working principle:

[0030] 1) The double-output motor 7 drives the two driving worms 8 to rotate synchronously, and then drives the two connecting shaft sleeves 2 to rotate through the driven worm wheels 6, thereby driving the roller frames 3 to rotate an angle, so as to change the opening angles of the two roller frames 3, the transmission belt 4 and the bristles 5;

[0031] 2) Then the driving motor 11 drives the driving roller 17 to rotate, and then drives the transmission belt 4 to convey and rotate, and then drives several bristles 5 to sweep the bottom surface, and then the garbage is directed to the sewage suction cover 12;

[0032] 3) Then with the pushing, the garbage is sucked into the sewage suction cover 12, and then the industrial vacuum cleaner 13 sucks away the garbage.

[0033] In summary, for the road cleaning device, the dual-output motor 7 drives the two driving worms 8 to rotate synchronously. Then, the two connecting bushings 2 are driven to rotate by the driven worm wheels 6, thereby driving the roller frame 3 to rotate, changing the opening angles of the two roller frames 3, the transmission belt 4, and the bristles 5, so that the garbage on both sides is swept towards the middle. Moreover, by controlling the lower opening degree, the cleaning width can be adjusted to meet the cleaning requirements of different widths, improving the practicability. The sewage suction hood 12 is intercepted between the two roller frames 3, so that the swept garbage can be sucked away by the sewage suction hood 12 after being swept towards the middle, thus forming a larger cleaning width.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principle and purpose of the present invention.
