AI Technical Summary
Existing shoulder sweeping devices require drivers with advanced driving skills to adjust the relative position of the brush rollers and the shoulder, making it difficult to automatically adjust within a small range to ensure sweeping quality.
It adopts a structure consisting of a mounting plate, slider, vertical shaft, horizontal shaft, reference wheel, and spring. The brush cylinder is driven by a motor to rotate and the reference wheel contacts the ground to automatically adjust the relative position of the brush cylinder and the road shoulder. Combined with the spring to compensate for distance changes, it ensures the cleaning effect.
This technology ensures that the brush cylinder maintains effective contact with the road shoulder surface even when the sweeper is moving or the road shoulder is changing, thus improving the cleaning quality and reducing reliance on the driver's driving skills.

Technical Field
[0001] This utility model relates to the technical field of sanitation cleaning devices, specifically a shoulder cleaning device for sanitation vehicles. Background Technology
[0002] Sanitation vehicles are special vehicles used for urban sanitation and cleaning. They are mainly divided into water sprinkler trucks, garbage trucks, sewage suction trucks, high-pressure cleaning trucks, snow removal trucks, etc. There are also cleaning trucks used to scrub the shoulders of stones. However, most existing shoulder sweeping devices have brushes attached to the sweeper vehicle, and the relative position of the brush rollers and the shoulder is adjusted by driving the vehicle. Since the shoulder is narrow, the driver needs to have high driving skills to ensure the sweeping quality. Therefore, providing a sweeping device that can automatically adjust the relative position of the brush rollers and the shoulder within a small range is a technical problem that needs to be solved by those skilled in the art.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0013] Please see Figures 1-2This utility model provides a technical solution: a road shoulder cleaning device for sanitation vehicles, comprising: a mounting plate 1, fixedly mounted on a sweeper vehicle 21; a mounting plate 3, hinged to the mounting plate 1 via a pair of parallel connecting plates 2, the mounting plate 1, mounting plate 3, and the pair of connecting plates 2 forming a parallelogram structure, the mounting plate 3 and the mounting plate 1 always remaining parallel, and a spring 20 hinged between the mounting plate 1 and the connecting plates 2; a slider 4, slidably mounted on the mounting plate 3 in a vertical direction; and a vertical shaft 5, fixedly mounted at the bottom of the slider 4. A rotating cylinder 10 is rotatably mounted on the outer side of the slide block 4, and a brush cylinder 11 is fixedly mounted on the outer side of the rotating cylinder 10 for cleaning the side surface of the road shoulder; a horizontal shaft 7 is fixedly mounted on one side of the slide block 4, and a rotating cylinder 2 12 is rotatably mounted on the outer side of the slide block 4, and a brush cylinder 2 13 is fixedly mounted on the outer side of the rotating cylinder 2 12 for cleaning the upper surface of the road shoulder; a height reference wheel 6 is rotatably mounted on the bottom of the vertical shaft 5, and the height reference wheel 6 is in contact with the ground; a horizontal reference wheel 9 is rotatably mounted on the extension frame 8 on the slide block 4, and the horizontal reference wheel 9 is in contact with the side of the road shoulder.
[0014] As an embodiment of this utility model, a bevel gear 14 is fixedly installed on the upper end of the first rotating drum 10, a bevel gear 15 that meshes with the first bevel gear 14 is fixedly installed on the second rotating drum 12, a motor 16 is fixedly installed on the slider 4, and a bevel gear 17 is fixedly installed at the power output end of the motor 16. The bevel gear 17 meshes with the bevel gear 15, and the motor 16 can drive the first rotating drum 10 and the second rotating drum 12 to rotate simultaneously.
[0015] As an embodiment of this utility model, a protective cover 19 is provided on the slider 4, and the motor 16, bevel gear one 14, bevel gear two 15, and bevel gear three 17 are all located inside the protective cover 19.
[0016] As an embodiment of this utility model, a winch 18 is fixedly installed above the slider 4. The pull rope of the winch 18 is connected to the slider 4. When no sweeping operation is being carried out, the slider 4 can be pulled upward by the winch 18 winding the steel rope, so that the height reference wheel 6 is away from the ground.
[0017] The working principle and usage process of this utility model are as follows: During use, starting the motor 16 causes brush cylinder one 11 and brush cylinder two 13 to rotate simultaneously, releasing the winch 18 steel rope to bring the height reference wheel 6 into contact with the ground. This contact ensures the height of brush cylinder two 13. The driver then drives the sweeper 21 close to the road shoulder, bringing the lateral reference wheel 9 into contact with the side surface of the road shoulder. After the lateral reference wheel 9 contacts the road shoulder, the sweeper 21 is still driven towards the road shoulder, compressing the spring 20. The spring 20 generates… The thrust ensures that the lateral reference wheel 9 remains in close contact with the side surface of the road shoulder. The lateral reference wheel 9 maintains the correct distance between the brush cylinder 11 and the road shoulder. The rotating brush cylinders 11 and 23 clean the road shoulder. When the distance between the sweeper 21 and the road shoulder changes slightly (e.g., slight vehicle deviation, bending, depression, or protrusion along the length of the road shoulder), the spring 20 pushes the connecting plate 2 to compensate for the distance difference, preventing the brush cylinder 11 from being in close contact with the road shoulder due to slight changes in distance. Shoulder separation; additionally, the height reference wheel 6 should be made of a material with low friction with the road surface, and the edge of the wheel should be rounded to facilitate the lateral movement of the height reference wheel on the road surface through friction; when one side wheel of the sweeper 21 runs over a pothole or protrusion on the road surface (such as a protruding or sunken manhole cover, speed bump, etc.), the vehicle body will shake. At this time, the distance between the mounting plate 2 3 and the ground will either increase or decrease. The slider 4 can slide on the mounting plate 2 3, and the weight of the slider 4 can ensure that the height reference wheel 6 is always on the ground. Effective cleaning of the road shoulder surface is achieved to prevent the brush cylinder 13 from moving away from the road shoulder surface due to the shaking of the sweeper 21. After cleaning is completed, the winch 18 can be started to pull the slider 4 upward, so that the height reference wheel 6 is away from the ground. By setting a pull rope on the mounting plate 1 and setting a hook (not shown in the figure) at its end, the mounting plate 23 is pushed towards the mounting plate 1 and the spring 20 is compressed. The hook is attached to the mounting plate 23 to prevent the mounting plate 23 from shaking randomly, which makes it easy for the sweeper 21 to move when no cleaning operation is being carried out.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
