Description

Technical Field

[0001] The utility model relates to the technical field of unmanned sweeping vehicles, and more specifically, to an adaptive garbage collecting and dumping device of an unmanned sweeping vehicle. Background Art

[0002] As an important tool for modern urban cleaning, the driverless street sweeper has a powerful cleaning ability that enables it to perform well in various complex and changeable road conditions, from bustling squares to wide highways, from cozy residential areas to busy parking lots, whether it is crowded docks, airports, stations, or cement plants and power plants in industrial areas, the driverless street sweeper can easily cope with it, bringing cleanliness and tidiness to these places. In the square, it can quickly and effectively clean up all kinds of waste to keep the square clean and beautiful. On the highway, its efficient cleaning system can quickly remove fallen leaves, paper scraps and other debris on the road to ensure driving safety. In residential areas, it not only provides residents with a comfortable living environment, but also reduces In order to increase the labor intensity of manual cleaning, the cleaning range of an unmanned sweeper is usually determined by the position and configuration of the cleaning brush. In order to expand the cleaning range, some advanced unmanned sweepers have adopted a design in which the cleaning heads are installed on both sides of the vehicle. This design enables the sweeper to simultaneously clean garbage and dust on both sides of the road, greatly improving the cleaning efficiency. However, when the unmanned sweeper encounters a situation where the road is too narrow or there is an obstacle in front, the cleaning brush is too close to the edge of the road and may collide with roadside facilities or obstacles, causing equipment damage or reduced cleaning effect. Similarly, if there is an obstacle in front, the cleaning brush cannot be avoided in time and thus comes into contact with the obstacle, so it needs to be improved and optimized.

[0022] By starting the hydraulic cylinder 12, the output shaft of the hydraulic cylinder 12 is extended and retracted to drive the two connecting rods 2 13 to move, and the connecting rod 2 13 is hingedly connected to the two connecting rods 11, thereby driving the two connecting rods 11 to rotate with the axis hinged to the fixed block 10 as the center, and the two connecting rods 11 drive the two rotating rods 3 15 and the cleaning brush 2 14 to move together. Compared with the traditional device, this design enables the position of the cleaning brush 2 14 to be flexibly adjusted, especially when entering a narrow road or encountering obstacles ahead, the sweeper can respond quickly and adjust the position of the cleaning brush 2 14, and by adjusting the extension and retraction of the output shaft of the hydraulic cylinder 12, the cleaning brush 2 14 can move inward to narrow its working range, thereby avoiding collision with the sides of the road or obstacles, ensuring that the sweeper can safely and smoothly pass through narrow or complex environments.

[0023] When the unmanned sweeper is performing cleaning operations, it is first necessary to start the motor 4 21, and drive the corresponding rotating rod 3 15 to rotate with the cooperation of the belt 2 16, and then start the motor 3 28, and drive the other rotating rod 3 15 to rotate under the action of the belt 4 29, thereby driving the two cleaning brushes 2 14 to rotate. At the same time, start the motor 1 4, and the output shaft of the motor 1 4 drives the gear 1 5 to rotate, and the gear 1 5 meshes with the gear 2 7 to drive the gear 2 7 to rotate, and the gear 2 7 drives the rotating rod 2 6 to rotate, and then under the action of the belt 1 8, the two rotating rods 1 2 rotate in opposite directions, and the two rotating rods 1 The two cleaning brushes 13 are driven by the hydraulic cylinder 12 to rotate and clean the ground. When a narrow road or an obstacle is encountered in front, the hydraulic cylinder 12 is started, and the output shaft of the hydraulic cylinder 12 is extended and retracted to drive the two connecting rods 2 13 to move. The connecting rod 2 13 is hingedly connected with the two connecting rods 11, thereby driving the two connecting rods 11 to rotate with the axis hinged with the fixed block 10 as the center. The two connecting rods 11 drive the two rotating rods 3 15 and the cleaning brush 2 14 to move inward, narrowing their working range, thereby avoiding collision with the sides of the road or obstacles.

[0024] Among them, a collecting box 20 is hingedly installed on the top of the vehicle base 1, a motor four 21 is fixedly installed on the front of the collecting box 20, four supporting blocks 24 are fixedly installed on the top of the collecting box 20, and a threaded rod 22 is rotatably installed on one side of two corresponding supporting blocks 24 close to each other. The top of the threaded rod 22 passes through the corresponding supporting block 24, and a belt three 23 is wound around the outer wall of the threaded rod 22 and the output shaft of the motor four 21. A cleaning plate 25 is threadedly sleeved on the outer wall of the threaded rod 22, and the outer wall of the cleaning plate 25 is slidably connected to the inner wall of the collecting box 20.

[0025] By starting motor four 21, under the action of belt three 23, the output shaft of motor four 21 drives the threaded rod 22 to rotate, and the threaded connection between the threaded rod 22 and the cleaning plate 25 drives the cleaning plate 25 to move inside the collection box 20, thereby cleaning the inner wall of the collection box 20, effectively preventing garbage residue and accumulation. Compared with traditional devices, by setting the cleaning plate 25, it is possible to effectively prevent garbage residue and accumulation inside the collection box 20, thereby extending the service life of the collection box 20 and further reducing maintenance costs.
