[0002] Watering is a crucial part of road maintenance, especially in the high temperatures of summer, as it helps cool the road surface. Existing road maintenance equipment comes in various forms, such as passively traction types and self-powered types. For example, Chinese Patent Document CN221681723U discloses a road maintenance watering device that can effectively filter the water flow during watering; however, this device cannot clean the road surface before watering, allowing various impurities to easily mix with the water, solidify, and clump together, affecting the road surface smoothness. Another road maintenance device disclosed in Chinese Patent Document CN221441258U has brushes whose movement range is limited to between two dust collection boxes, making it difficult to adjust the cleaning area as needed. Therefore, further improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a road maintenance vehicle with adjustable sweeping range, flexible and versatile use, and simple and reasonable structure.

[0004] The technical solution adopted by this utility model is as follows: a road maintenance vehicle, including a vehicle body; a drive assembly is provided in the vehicle body; the drive assembly is connected to the walking wheels, characterized in that: two sweeping rollers are provided at the end of the vehicle body; the two sweeping rollers are connected to the vehicle body through swing arms; each swing arm is provided with a rotating part connected to the sweeping roller; a translation mechanism is provided between the two swing arms; the translation mechanism is connected to a cylinder.

[0005] Furthermore, a rotating shaft is provided at the other end of the swing arm relative to the cleaning roller; a shaft hole is provided on the vehicle body relative to the rotating shaft; the rotating shaft is rotatably connected to the shaft hole; a guide platform is also provided on the vehicle body; the guide platform is located between the two swing arms.

[0006] Furthermore, the translation mechanism includes a translation frame disposed on the outside of the guide platform; the cylinder is disposed on the surface of the guide platform; the piston of the cylinder is connected to the translation frame; the translation frame includes two side plates and a cross plate.

[0007] Furthermore, the side plates are located on both sides of the outer side of the guide plate; the horizontal plate is connected between the two side plates; and the piston of the cylinder is connected to the horizontal plate.

[0008] Furthermore, the translation mechanism also includes a linkage rod; one end of the linkage rod is provided with a sleeve; the sleeve is fixedly sleeved on the outside of the rotating shaft.

[0009] Furthermore, the other end of the linkage rod relative to the sleeve is provided with a slot; the upper surface of the side plate is provided with a slide rod; the slide rod is slidably connected in the slot.

[0010] Furthermore, a motor is also provided on the upper surface of the swing arm; the motor is arranged opposite to the cleaning roller.

[0011] Furthermore, a dust collection box is also provided on the surface of the vehicle body; a negative pressure pump is provided inside the dust collection box; the dust collection box is connected to the suction port; the suction port is located at the bottom of the vehicle body.

[0012] This invention offers the following advantages: By directly connecting the swing arms to the translation mechanism, the translation mechanism, under the action of the cylinder, moves horizontally while simultaneously driving the two swing arms to swing in opposite directions, i.e., to close or separate. This allows the sweeping roller, originally installed below the swing arms, to have a large sweeping area. Simultaneously, the closing process of the two swing arms gradually accumulates debris on the road surface towards the center, facilitating negative pressure adsorption at the suction port. Compared to the fixed brush movement range design in traditional technologies, this invention provides stronger coverage, and its dynamic sweeping process also offers better debris transfer capabilities.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] See Figures 1-3This application discloses a road maintenance vehicle, including a vehicle body 1; a drive assembly is provided inside the vehicle body 1; the drive assembly is connected to the walking wheels, and two sweeping rollers 2 are provided at the end of the vehicle body 1; the two sweeping rollers 2 are connected to the vehicle body 1 through swing arms 3; each swing arm 3 is provided with a rotating part connected to the sweeping roller 2; a translation mechanism is provided between the two swing arms 3; the translation mechanism is connected to a cylinder.

[0019] Furthermore, the other end of the swing arm 3 relative to the cleaning roller 2 is provided with a rotating shaft 4; the vehicle body 1 is provided with a shaft hole relative to the rotating shaft 4; the rotating shaft 4 is rotatably connected to the shaft hole; the vehicle body 1 is also provided with a guide platform 5; the guide platform 5 is located between the two swing arms 3.

[0020] Furthermore, the translation mechanism includes a translation frame 6 disposed on the outside of the guide platform 5; the cylinder is disposed on the surface of the guide platform 5; the piston of the cylinder is connected to the translation frame 6; the translation frame 6 includes two side plates 6-1 and a cross plate 6-2.

[0021] Furthermore, the side plates 6-1 are located on both sides of the outer side of the guide plate 5; the horizontal plate 6-2 is connected between the two side plates 6-1; and the piston of the cylinder is connected to the horizontal plate 6-2.

[0022] Furthermore, the translation mechanism also includes a linkage rod 7; one end of the linkage rod 7 is provided with a sleeve 7-1; the sleeve 7-1 is fixedly sleeved on the outside of the rotating shaft 4.

[0023] Furthermore, the other end of the linkage rod 7 relative to the sleeve 7-1 is provided with a slot 7-2; the upper surface of the side plate 6-1 is provided with a slide rod 8; the slide rod 8 is slidably connected in the slot 7-2.

[0024] Furthermore, a motor is also provided on the upper surface of the swing arm 3; the motor is arranged opposite to the cleaning roller 2.

[0026] Working principle: As the vehicle body 1 is pushed forward, the sweeping roller 2 rotates on the swing arm 3 under the action of the motor. At the same time, under the action of the cylinder, it pushes the translation frame 6 to move along the guide platform 5. Since the upper surface of the side plate 6-1 of the translation frame 6 is provided with a sliding rod 8, which is slidably connected in the slot 7-2 of the linkage rod 7, the linear movement of the sliding rod 8 will cause the linkage rod 7 to change angle. The linkage rod 7 is fixedly connected to the rotating shaft 4 through the sleeve 7-1, so the linkage rod 7 will drive the swing arm 3 to rotate. The two swing arms 3 can close or separate. When separated, it can expand the farthest position that the sweeping roller 2 can cover. When closed, it can cooperate with its rotation to transfer the debris on the outside of the vehicle body 1 to the bottom of the vehicle body 1, and then suck it into the dust collection box 9 through the suction port 10.
