Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-5 As shown, this embodiment provides a cleaning brush adjustment mechanism for a multi-functional road sweeping and cleaning vehicle, including a movable compartment 1, a movable mechanism disposed inside the movable compartment 1, a drive box 2 disposed on the lower side of the movable mechanism, a rotating shaft 3 disposed on the lower side of the drive box 2, a first buffer plate 4 disposed at one end of the rotating shaft 3, two sliding columns 5 disposed on one side of the first buffer plate 4, a sliding cylinder 6 elastically fitted on one side of each of the two sliding columns 5, and the sliding columns 5 slidingly fitted inside the sliding cylinder 6, wherein a spring 7 connected to the sliding column 5 is disposed inside the sliding cylinder 6, a second buffer plate 8 disposed at one end of each of the two sliding cylinders 6, a connecting member disposed at one end of the second buffer plate 8, and a brush mechanism disposed on the connecting member.

[0026] One application of this embodiment is as follows: When in use, if the ground is uneven or has a large number of potholes, the potholes will first collide with the brush plate mechanism and cause it to move. Then, the connecting piece will drive the second buffer plate 8 to move. The movement of the second buffer plate 8 can drive the sliding cylinder 6 to move. At the same time, the movement can compress and contract the spring 7, so that the second buffer plate 8 and the first buffer plate 4 are brought closer to each other, thereby absorbing the impact force generated by the impact. When the brush plate mechanism moves out of the pothole, the elastic force of the spring 7 can drive the brush plate mechanism to reset, so that it can normally apply force to the flat ground, thus completing the use of this device.

[0027] By incorporating the sliding cylinder 6, sliding column 5, and spring 7, the brush mechanism, when encountering potholes in the road surface, compresses the spring 7, causing the sliding column 5 to contract within the sliding cylinder 6. This contraction buffers and absorbs the impact force and the elasticity of the spring 7, allowing the equipment to function normally with potholes of varying sizes and preventing damage from contact with them. This expands the brush mechanism's usability across different road surfaces and broadens its practical application. Furthermore, the moving mechanism allows for adjustment of the brush mechanism's height and angle, facilitating cleaning at different angles during operation.

[0028] like Figure 3 and 5As shown, in this embodiment, a limiting plate 9 is provided at one end of the sliding column 5. One side of the limiting plate 9 is connected to the spring 7, and the limiting plate 9 is slidably fitted inside the sliding cylinder 6. With the limiting plate 9, when the brush mechanism encounters potholes or uneven ground, the sliding column 5 and the sliding cylinder 6 can be more stable during reciprocating movement due to the mutual limiting between the limiting plate 9 and the inner wall of the sliding cylinder 6 when the spring 7 is compressed to move the sliding column 5 inside the sliding cylinder 6. This improves the stability of the brush mechanism when cleaning potholes or uneven surfaces.

[0029] like Figure 1-4 As shown, the connector in this embodiment includes a connecting rod 10 disposed at one end of the second buffer plate 8. A limiting plate 11 is disposed at one end of the connecting rod 10. A plurality of limiting grooves 12 are provided on the limiting plate 11. A limiting cover 13 connected to the brush plate mechanism is sleeved on the limiting grooves 12. The limiting plate 11 is engaged with the brush plate mechanism. The brush plate mechanism includes a cleaning brush 14 threadedly fitted in the limiting cover 13. A threaded ring 15 is disposed on the cleaning brush 14. A threaded coil 16 is disposed in the limiting cover 13. The threaded ring 15 and the threaded coil 16 are engaged. A plurality of limiting blocks 17 are disposed on the inner circumference of the threaded ring 15. The limiting blocks 17 are engaged with the limiting grooves 12. In this embodiment, the connecting rod 10 on the rotating shaft 3 can be rotated by the drive box 2. The rotation of the connecting rod 10 can drive the limiting plate 11 to rotate. With the mutual engagement between the limiting plate 11 and the limiting block 17 inside the threaded ring 15, it is convenient to drive the cleaning brush 14 to rotate. It is also convenient to disassemble and assemble the cleaning brush 14. With the setting of the threaded ring 15 and the threaded coil 16, it is convenient to replace the cleaning brush 14. It is convenient to replace and maintain the frequently used cleaning brush 14 in the future, making the replacement of the cleaning brush 14 more convenient and quick, and easier for the operator to operate.

[0030] like Figure 2As shown, the moving mechanism of this embodiment includes toothed plates 18 disposed on both sides of the inner wall of the moving chamber 1, two gears 19 meshing with the toothed plates 18, a moving motor chamber 20 disposed between the two gears 19, a first connecting bridge 21 connected to the drive box 2 disposed on the lower side of the moving motor chamber 20; a second connecting bridge 22 movably connected to the first connecting bridge 21 disposed on the drive box 2, wherein a motor is disposed inside the drive box 2, and the output end of the motor is connected to the rotating shaft 3; a telescopic rod 23 is movably connected to the lower side of the moving motor chamber 20, a connecting block is disposed on one side of the second connecting bridge 22, and one end of the telescopic rod 23 is movably connected to the connecting block. With the mobile motor compartment 20 in place, it can drive two gears 19 to rotate. The rotation of the two gears 19, through their meshing relationship with the toothed plate 18, can drive the mobile motor compartment 20 to move within the mobile compartment 1. During the movement, the angle of the sweeping brush disc 14 can be adjusted through the movable connection between the telescopic rod 23, the first connecting bridge 21, and the second connecting bridge 22, so as to sweep the road surface at different angles.
