[0002] At present, the garbage on the sidewalk is basically cleaned manually, with heavy tasks and high labor costs. With the increasing aging of the population, the number of people engaged in this job will gradually decrease in the future. Against this background, small cleaning vehicles for cleaning sidewalks have emerged. However, the road conditions of sidewalks are complex and the width of road piles is small, resulting in a small overall width of the small cleaning vehicle, which affects the layout of the cleaning device. Moreover, after the cleaning device of the traditional model is deployed, its cleaning width cannot be adjusted, and when encountering a dead-end road, it is impossible to clean the garbage in front.

Detailed implementation manners

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-7 shown, the present utility model discloses a cleaning device for a small cleaning vehicle, including:

[0027] A bracket 1 for mounting a cleaning mechanism 2;

[0028] A cleaning mechanism 2 for cleaning garbage, the cleaning mechanisms 2 are symmetrically arranged below the bracket 1, and each includes a sweeping disc 24, a height adjustment assembly 23, a swing assembly 21 and a limiting assembly 22. The height adjustment assembly 23 and the limiting assembly 22 are both connected to the swing assembly 21. The sweeping disc 24 is arranged below the height adjustment assembly 23. The swing assembly 21 controls the left and right swing of the height adjustment assembly 23 and the sweeping disc 24, and the height adjustment assembly 23 controls the up and down movement of the sweeping disc 24.

[0029] The cleaning device discloses a height adjustment assembly 23, a swing assembly 21 and a limiting assembly 22. The height adjustment assembly 23 adjusts the height of the sweeping disc 24, the swing assembly 21 controls the swing direction and swing angle of the sweeping disc 24, and the limiting assembly 22 is used to adjust the maximum swing angle of the sweeping disc 24, realizing the adjustment of the cleaning width of the sweeping disc 24, changing the relative position between the sweeping disc 24 and the cleaning vehicle, enabling the sweeping disc 24 to complete work on various road conditions and improving the cleaning effect.

[0030] In some embodiments of the present utility model, the swing assembly 21 includes a fixing plate 211, a swing motor 212, a rotating shaft 213, a mounting seat 214 and a swing plate 215. The fixing plate 211 is installed below the bracket 1 and fixedly connected to the bracket 1 for fixing the swing motor 212. The mounting seat 214 is connected to the fixing plate 211. The rotating shaft 213 is rotatably arranged between the two mounting seats 214. One side of the swing plate 215 is fixedly connected to the swing motor 212, and the other side is rotatably connected to the rotating shaft 213. The swing motor 212 is connected to the swing plate 215 to make the swing plate 215 rotate around the rotating shaft 213. The swing plate 215 is connected with a height adjustment assembly 23, thereby driving the sweeping disc 24 to swing. The swing assembly 21 is controlled by a motor, with high control precision, simple structure and convenient maintenance.

[0031] In some embodiments of the present utility model, the limiting assembly 22 includes a limiting rod 221 and a torsion spring 222. The limiting rod 221 is arranged on one side of the fixing plate 211, and the torsion spring 222 is sleeved on the outer surface of the rotating shaft 213. When the swing plate 215 rotates, one side of the swing plate 215 abuts against the limiting rod 221 to limit the rotation of the swing plate 215. The limiting rod 221 limits the maximum rotation angle of the swing plate 215, and the torsion spring 222 provides a reset function for the swing plate 215.

[0032] In some embodiments of the present utility model, the limiting rod 221 has a limiting end 2211, and the distance between the limiting end 2211 and the fixing plate 211 is adjustable. By adjusting the distance between the limiting end 2211 and the fixing plate 211, the maximum swing angle of the swing plate 215 can be changed, thereby changing the maximum swing angle of the sweeping disc 24.

[0033] In some embodiments of the present utility model, the torsion spring 222 has a first insertion portion 2221 and a second insertion portion 2222. The swing plate 215 has a first fixing portion 2111 for fixing the first insertion portion 2221 and a second fixing portion 2151 for fixing the second insertion portion 2222. The first fixing portion 2111 and the second fixing portion 2151 facilitate the insertion of the first insertion portion 2221 and the second insertion portion 2222, facilitate the fixing of the torsion spring 222, and improve the stability of the torsion spring 222.

[0034] In some embodiments of the present utility model, the height adjustment assembly includes a sweeper mounting bracket 231, an adjustment pull rod 232, a lifting push rod 233 and a lifting link 234. The sweeper 24 is installed below the sweeper mounting bracket 231 through a driving motor 25. One end of the adjustment pull rod 232 and the lifting link 234 is hinged to the swing plate 215, and the other end is hinged to the sweeper mounting bracket 231. One end of the lifting push rod 233 is hinged to the sweeper mounting bracket 231, and the other end is hinged to the swing plate 215 through a connecting member 235. When the lifting push rod 233 extends or retracts, the lifting push rod 233 and the lifting link 234 rotate around the swing plate 215, driving the sweeper mounting bracket 231 and the sweeper 24 to move up and down, completing the height adjustment of the sweeper 24.

[0035] In some embodiments of the present utility model, the cleaning mechanism 2 further includes a self-floating spring 26. One end of the self-floating spring 26 is connected to the swing plate 215, and the other end is connected to the sweeper mounting bracket 231.

[0036] The sweeper 24 is in contact with the ground during operation, and the brush on the sweeper 24 has a certain hardness, so the sweeper 24 will give itself an upward supporting force when working. When the lifting rod extends, the sweeper 24 descends, and when the lifting rod retracts, the sweeper 24 ascends. The self-floating spring 26 provides an upward pulling force for the sweeper 24, so that the sweeper 24 maintains a set contact area with the ground.

[0037] During the normal operation of the vehicle, the lifting push rod 233 extends completely and no longer provides a pulling force for the sweeper 24. The sweeper 24 descends and contacts the ground under the action of its own gravity. The sweeper 24 maintains balance under the action of its own gravity, the pulling force provided by the self-floating spring 26, and the supporting force of the ground on the sweeper 24, and can float up and down with the unevenness of the ground, and the sweeper 24 always remains in contact with the ground. The swing motor 212 rotates to drive the swing plate 215 to rotate. The swing plate 215 rotates under the reaction force of the torsion spring 222, thereby driving the sweeper 24 to unfold. The limit rod 221 contacts the swing plate 215 for limiting. By adjusting the distance between the limit end 2211 and the fixing plate 211, the unfolding width of the sweeper 24 can be changed.

[0038] As Figure 4 shown, when the sweeper 24 encounters an obstacle in the vehicle width direction, the obstacle exerts a resistance on the sweeper 24, causing the sweeper 24 to rotate against the torsion of the torsion spring 222. After passing the obstacle, the sweeper 24 rotates and resets under the torsion of the torsion spring 222 to complete obstacle avoidance.

[0039] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
