[0042] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] The present invention provides a road sweeper and a cleaning method, which are used to reduce the labor intensity of workers, simplify the structure of the road sweeper, reduce the requirements on the operator, increase the operating range of the road sweeper, and improve the road cleaning efficiency.

[0044] like Figures 1 to 5As shown, the road sweeper includes a body 1, wheels 2, a lifting mechanism 3, a transmission mechanism 4 and a cleaning member. The wheel 2 is rotatably connected to the body 1 and can rotate around a first axis; the lifting mechanism 3 is connected to the body 1, and the lifting mechanism 3 includes a telescopic rod 31, and the telescopic rod 31 can be telescoped in a vertical direction; the transmission mechanism 4 includes a first transmission member 41 and a second transmission member 42, one end of the first transmission member 41 is movably connected to the wheel 2 and is eccentrically arranged relative to the first axis, the other end of the first transmission member 41 is movably connected to one end of the second transmission member 42, and the other end of the second transmission member 42 is rotatably connected to the telescopic rod 31, and the rotation of the wheel 2 can drive the second transmission member 42 to swing back and forth around the telescopic rod 31 through the first transmission member 41; the cleaning member is detachably connected to the second transmission member 42.

[0045] When in use, the cleaning worker drives the road sweeper to the road section to be cleaned, installs and fixes the cleaning piece and the second transmission member 42, and the telescopic rod 31 is extended to drive the cleaning piece to move down to abut against the road surface. When the road sweeper is driving along the road, the wheel 2 rotates through the first transmission member 41 to drive the second transmission member 42 to swing back and forth around the telescopic rod 31, so that the cleaning piece can make an arc-shaped reciprocating motion on the road surface, and the road surface is cleaned, which reduces the labor intensity of the workers and improves the road cleaning efficiency. The cleaning piece can be driven to move by the rotation of the wheel 2, and no additional power source is required. The operation is simple, the requirements for the operator are low, and the structure is simple, the space occupied is small, and it can travel on narrow and uneven roads, which improves the operating range of the road sweeper. When the road does not need to be cleaned, the telescopic rod 31 is shortened to drive the cleaning piece to move up away from the road surface, avoid the friction between the cleaning piece and the road, and improve the service life of the cleaning piece. The cleaning worker drives the road sweeper to a safe section and disassembles the cleaning piece.

[0046] The wheels 2 can be arranged at the bottom of the vehicle body 1, or can be distributed on the left and right sides of the vehicle body 1. In this embodiment, the wheels 2 are distributed on the left and right sides of the vehicle body 1, and the wheels 2 are rotatably connected to the vehicle body 1 to ensure that the wheels 2 can drive the vehicle body 1 forward when rolling on the ground, and the axes of the wheels 2 on the left and right sides are in line, thereby improving the driving stability.

[0047] The wheel 2 rotates to drive the vehicle body 1 to move. The wheel 2 may be a wheel 2 with a hub motor, or may be a wheel 2 driven by an external motor. For example, the wheel 2 is driven by a motor, which is disposed at the bottom of the vehicle body 1 to save space. The motor is connected to the wheel 2 to drive the wheel 2 to rotate, thereby driving the vehicle body 1 forward or backward.

[0048] The wheels 2 may be provided in three or four forms. When there are three wheels 2, two of them are symmetrically arranged at the left and right sides of the rear part of the vehicle body 1, and another wheel 2 is arranged at the middle of the front part of the vehicle body 1, and the three wheels 2 are arranged in a triangle to improve the stability of the vehicle body 1. When there are four wheels 2, two of them are arranged at the left and right sides of the front part of the vehicle body 1, and the other two wheels 2 are arranged at the left and right sides of the rear part of the vehicle body 1, and the four wheels 2 are arranged in a rectangular form.

[0049] The vehicle body 1 can be a support plate or an existing vehicle frame, and the operator can stand or sit on the vehicle body 1. When the vehicle body 1 is a support plate, a seat is provided on the support plate, and the operator can sit on the seat to improve comfort.

[0050] The lifting mechanism 3 can be an electric push rod or a cylinder. The telescopic rod 31 of the lifting mechanism 3 can be lifted and lowered in the vertical direction, driving the second rotating member 42 to move in the vertical direction, and then driving the cleaning member to move in the vertical direction, so as to realize the switching of the cleaning member between the working state and the standby state.

[0051] The lifting mechanism 3 can be fixedly connected to the outer surface of the vehicle body 1, or can be inserted through the vehicle body 1. For example, the vehicle body 1 is provided with an avoidance cavity in the vertical direction, and at least part of the lifting mechanism 3 is located inside the avoidance cavity, that is, the lifting mechanism 3 is inserted through the vehicle body 1, which can save installation space. In order to facilitate the connection between the lifting mechanism 3 and the vehicle body 1, a flange can be provided on the lifting mechanism 3, and the flange is fixedly connected to the vehicle body 1 by bolts to achieve a fixed connection between the lifting mechanism 3 and the vehicle body 1.

[0052] See also Figure 1 and Figure 2 The wheel 2 includes an axle 21 and a wheel body 22. The axle 21 is rotatably disposed through the vehicle body 1, the wheel body 22 is fixedly connected to the axle 21, and the first transmission member 41 is eccentrically connected to the axle 21 or the wheel body 22. The axle 21 is rotatably disposed through the vehicle body 1, which is convenient for installation. The first transmission member 41 is eccentrically connected to the axle 21 or the wheel body 22, ensuring that when the wheel 2 rotates, the portion where the first transmission member 41 is connected to the wheel 2 can rotate around the axis of the axle 21, so that the other end of the first transmission member 41 generates a displacement difference in the forward direction of the vehicle body 1, driving the second transmission member 42 to rotate around the lifting mechanism 3.

[0053] Exemplarily, the first transmission member 41 is eccentrically connected to the axle 21. The transmission mechanism 4 also includes an adapter 43, which is fixedly connected to the axle 21 and extends radially of the axle 21, and the first transmission member 41 is hinged to the adapter 43. The adapter 43 extends radially along the axle 21 to facilitate the eccentric connection between the first transmission member 41 and the wheel 2. When the vehicle body 1 travels on an uneven ground, the articulation can reduce the impact force of the ground on the first transmission member 41 and increase the service life of the first transmission member 41. The adapter 43 can be plate-shaped or rod-shaped, and the shape of the adapter 43 is not specifically limited here.

[0054] The first transmission member 41 is hinged to the adapter member 43, which may be connected by a pin shaft, a universal joint, etc. In this embodiment, the first transmission member 41 is connected to the adapter member 43 by a hinge mechanism 5, which includes a hinge seat 51, a hinge shaft 52 and a limit plate 53. The adapter member 43 is provided with a hinge seat 51 at one end away from the wheel shaft 21, and a rotating hole is provided at one end of the first transmission member 41 close to the hinge seat 51. A hinge shaft 52 is provided in the rotating hole. One end of the hinge shaft 52 is interference fit with the hinge seat 51, and the other end of the hinge shaft 52 is fixedly connected to the limit plate 53 to limit the first transmission member 41 and prevent the first transmission member 41 from being separated from the hinge shaft 52.

[0055] Exemplarily, the first transmission member 41 is eccentrically connected to the wheel body 22. The transmission mechanism 4 further includes a connecting rod, which extends parallel to the first axis and is eccentrically arranged on the wheel body 22, and the first transmission member 41 is hinged to the connecting rod. The setting of the connecting rod realizes the eccentric connection between the first transmission member 41 and the wheel body 22. The hinge can reduce the impact force of the road on the first transmission member 41 and increase its service life.

[0056] The connecting rod can be integrally formed with the wheel body 22, or can be detachably connected to the wheel body 22. Exemplarily, the connecting rod is detachably connected to the wheel body 22, and it is easy to disassemble and repair the connecting rod when it is damaged. A fixing piece is fixedly provided on the wheel body 22, and the fixing piece is provided with a first threaded hole. One end of the connecting rod is inserted into the first threaded hole and threadedly connected to the fixing piece, and the end of the first transmission member 41 close to the connecting rod is connected to the wheel body 22 through an existing hinge structure. The connecting rod can be a square rod or a round rod, and the shape of the connecting rod is not specifically limited here.

[0057] The first transmission member 41 and the second transmission member 42 are connected by a ball joint, so that the first transmission member 41 and the second transmission member 42 can be transmitted smoothly, interference is avoided, and working stability is improved. When the wheel 2 drives the first transmission member 41 to move, since the wheel 2 is rotating, the first transmission member 41 will generate displacement components in both the vertical direction and the horizontal direction. The ball joint connection allows the first transmission member 41 and the second transmission member 42 to rotate relative to each other, avoiding the displacement component of the first transmission member 41 in the vertical direction from being transmitted to the second transmission member 42, ensuring that the cleaning member is in good contact with the ground, and improving the cleaning effect of the cleaning member on the road surface.

[0058] Specifically, an existing ball joint structure can be selected, and the ball joint structure includes a ball head and a ball joint seat. The ball head is fixedly connected to the end of the first transmission member 41 away from the wheel 2, and the ball joint seat is connected to the second transmission member 42. The ball head and the ball joint seat are rotatably connected. The ball head is fixedly provided with a threaded rod, and the first transmission member 41 is provided with a second threaded hole. The ball head is threadedly connected to the first transmission member 41 for easy installation. The ball joint seat can be integrally formed with the second transmission member 42, and can also be detachably connected to the second transmission member 42. Exemplarily, the ball joint seat is detachably connected to the second transmission member 42 for easy disassembly and maintenance.

[0059] The ball joint seat can be rotatably connected to the second transmission member 42, or can be fixedly connected to the second transmission member 42. Exemplarily, the ball joint seat is rotatably connected to the second transmission member 42 to increase the degree of freedom and make the transmission smoother. The ball joint seat is connected to the second transmission member 42 through a rotating connection mechanism 6. The rotating connection mechanism 6 includes a mounting block 61, a rotating shaft 62 and a limit pin 63. The mounting block 61 is fixedly connected to the ball joint seat and is provided with a through hole. The rotating shaft 62 is passed through the through hole and both ends pass through the second transmission member 42. The limit pin 63 is inserted into both ends of the rotating shaft 62 to prevent the ball joint seat from being separated from the second transmission member 42, thereby improving the transmission stability.

[0060] The first transmission member 41 and the second transmission member 42 may be rod-shaped or plate-shaped, which can save installation space. This embodiment does not specifically limit the shapes of the first transmission member 41 and the second transmission member 42.

[0061] The second transmission member 42 drives the cleaning member to swing back and forth along the road surface. The second transmission member 42 can extend in a straight line or bend to extend. For example, the second transmission member 42 bends to extend to avoid interference with the vehicle body 1. Figure 4 and Figure 5The second transmission member 42 includes a first connection portion 421 and a second connection portion 422 that are fixedly connected. The first connection portion 421 and the second connection portion 422 are arranged at an angle. The first connection portion 421 is movably connected to the first transmission member 41, and the cleaning member is fixedly connected to the second connection portion 422 and is detachable. The first connection portion 421 and the second connection portion 422 are arranged at an angle, which facilitates the adjustment of the extension direction of the second connection portion 422, so that the second connection portion 422 can swing symmetrically with respect to the forward direction of the vehicle body 1, ensuring that the cleaning member can symmetrically clean the roads on both sides of the vehicle body 1, thereby improving the cleaning efficiency.

[0062] The angle between the first connection portion 421 and the second connection portion 422 may be 30°, 45°, 60°, 75°, 90°, 105° or 120°. For example, the angle between the first connection portion 421 and the second connection portion 422 is 90° for easy processing.

[0063] The second connection part 422 can be threadedly connected, plugged or tied to the cleaning member. In this embodiment, the second connection part 422 includes a mounting port 4221, the end of the cleaning member is inserted into the mounting port 4221, and the cleaning member is threadedly connected to the second connection part 422 or locked by a locking member 100. The cleaning member is fixedly connected to the second transmission member 42, and is easy to disassemble.

[0064] The cleaning member is provided with a mounting rod, which is convenient for connection with the second transmission member 42. When the cleaning member is threadedly connected to the second connecting portion 422, the outer surface of the mounting rod is provided with a thread, the inner wall of the mounting port 4221 is provided with a thread, and the mounting rod is threadedly connected to the mounting port 4221. When the cleaning member is plugged into the second connecting portion 422, the shape of the mounting rod is the same as the mounting port 4221, which facilitates the insertion of the mounting rod into the mounting port 4221. Exemplarily, the shape of the mounting rod and the mounting port 4221 is rectangular, and the mounting rod will not rotate relative to the mounting port 4221 after being inserted into the mounting port 4221, thereby improving the connection firmness. The locking member 100 can be a bolt or a screw, which is easy to obtain and easy to install.

[0065] The second transmission member 42 is rotatably connected to the telescopic rod 31, so that the second transmission member 42 can swing around the telescopic rod 31, thereby realizing the swing of the cleaning member. Exemplarily, a mounting hole is provided on the second transmission member 42 in the vertical direction, the telescopic rod 31 is penetrated through the mounting hole, and the telescopic rod 31 is provided with a limiting member on the upper side and the lower side of the second transmission member 42. The limiting member limits the second transmission member 42 in the vertical direction, which can ensure that the telescopic rod 31 can move in the vertical direction to drive the second transmission member 42 to move, and prevent the cleaning member from interfering with the vehicle body 1. This embodiment does not specifically limit the size of the mounting hole, as long as the telescopic rod 31 can pass through the mounting hole. The limiting member can be a pin shaft, which is easy to obtain and convenient to connect.

[0066] Since the first connection part 421 and the second connection part 422 are arranged at an angle, the telescopic rod 31 is rotatably arranged at the junction of the first connection part 421 and the second connection part 422. The rotation radius of the second connection part 422 can be maximized, thereby increasing the cleaning area of ​​the cleaning member. At the same time, a mounting hole is arranged at the junction of the first connection part 421 and the second connection part 422, which can reduce stress concentration and increase the service life of the second transmission member 42.

[0067] The present embodiment also provides a road cleaning method, which uses the above-mentioned road sweeper, including: in the working state, the telescopic rod 31 is extended to drive the cleaning member to move downward to be close to the road surface. When the road sweeper is driving along the road, the wheel 2 rotates through the first transmission member 41 to drive the second transmission member 42 to swing back and forth around the telescopic rod 31, and the cleaning member swings back and forth around the telescopic rod 31 to clean the road surface; in the standby state, the telescopic rod 31 is shortened to drive the cleaning member to move upward to be away from the road surface, and the road sweeper can drive or park normally on the road.

[0068] The above method can adjust the distance between the cleaning member and the road surface through the telescopic rod 31. When the road sweeper is traveling on a section of road that needs to be cleaned, the telescopic rod 31 descends to make the cleaning member in the working position, that is, the cleaning member is in contact with the ground. As the wheel 2 rotates, the cleaning member makes an arc-shaped reciprocating motion along the road surface, thereby cleaning the road surface; when the road sweeper is traveling on a section of road that does not need to be cleaned, the telescopic rod 31 rises to drive the cleaning member away from the road surface and puts the cleaning member in the standby position, that is, the cleaning member does not contact the road surface, thereby reducing the wear of the cleaning member and increasing the service life of the cleaning member.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
