Example one
Referring to fig. 1 to 4 in combination with fig. 5 to 7, the present embodiment provides a cleaning brush mechanism; fig. 1 is a first structural schematic diagram of a cleaning disc brush mechanism provided in the embodiment; fig. 2 is a schematic structural diagram of a first frame of the cleaning disc brush mechanism provided in this embodiment; fig. 3 is a schematic structural diagram of a lifting assembly of the cleaning disc brush mechanism provided in this embodiment; fig. 4 is a schematic structural diagram of a disk brush assembly of the cleaning disk brush mechanism provided in this embodiment.
The cleaning disc brush mechanism provided by the embodiment is used for a road sweeper.
Referring to fig. 1 to 4 in combination with fig. 5 to 7, the cleaning brush mechanism 1 of the present embodiment includes a first frame 10, a brush assembly 12, and a lifting assembly 13.
The first frame 10 is used to connect the chassis of the road sweeper 2, alternatively, the first frame 10 may be integrally formed with the chassis of the road sweeper 2, or the first frame 10 may be a sub-frame for fixedly supporting the sweeping disk brush mechanism 1.
The elevating assembly 13 is connected between the first frame 10 and the brush assembly 12 to move the brush assembly 12 toward or away from the first frame 10. On the one hand, the lifting component 13 plays a role of connecting the disc brush component 12 to the first frame 10, and on the other hand, the disc brush component 12 can be driven to lift by arranging the lifting component 13. Specifically, when the sweeping disk brush assembly 12 is disposed on the road sweeper 2, the lifting assembly 13 is capable of driving the disk brush assembly 12 between the road surface and the first frame 10.
Optionally, the brush assembly 12 is disposed on the second frame 11, and the lifting assembly 13 is connected between the first frame 10 and the second frame 11, so that the brush assembly 12 moves synchronously with the second frame 11. Specifically, the disc brush assembly 12 can move between the road surface and the first frame 10 with the second frame 11 driven by the elevating assembly 13, so that the disc brush assembly 12 can be brought into contact with the road surface to clean the road surface by the disc brush assembly 12, or the disc brush assembly 12 can be stored away from the road surface at a position close to the second frame 11 when there is no need to clean the road surface.
The disc brush assembly 12 includes a disc brush 120 rotatably coupled to the second frame 11, and when the disc brush assembly 12 moves to contact the road surface, the effect of sweeping the road surface can be achieved by the rotation of the disc brush 120, so as to sweep and gather the garbage, dust, stones, etc. on the road surface.
The cleaning brush assembly 1 of the present embodiment is different from the conventional manual cleaning scheme for road surfaces, and can clean road surfaces by rotating the disk brush 120 of the disk brush assembly 12, and can lift the disk brush assembly 12 by the lifting assembly 13, so that the disk brush assembly 12 is switched between a cleaning state and a storage state. The cleaning disc brush mechanism 1 not only reduces the labor intensity of sanitation workers, but also improves the efficiency and the quality of road cleaning work.
In an alternative of this embodiment, as shown in fig. 2 and 3, the lifting assembly 13 includes a first rotary driving device 130 disposed on the first frame 10, a lead screw 131, and a lead screw nut 132 fixedly connected to the second frame 11 with the disc brush assembly 12. The first rotary drive device 130 is capable of performing rotational drive.
The screw rod 131 extends along a first direction, and both ends of the screw rod 131 are respectively a smooth end and a threaded end. Wherein, the smooth end refers to the end of the screw rod 131 without external threads on the periphery, and the threaded end refers to the end of the screw rod 131 with threads on the periphery. Alternatively, the first direction is a direction perpendicular to the chassis of the vehicle body 20.
The first rotary driving means 130 is drivingly connected to the smooth end of the lead screw 131 to rotate the lead screw 131 about its axis, and the threaded end of the lead screw 131 is threadedly engaged with the lead screw nut 132. When the first rotary driving device 130 drives the smooth end of the lead screw 131 to rotate, the lead screw nut 132 is screwed in or out with respect to the threaded end of the lead screw 131. Since the lead screw 131 is disposed on the first frame 10 and the lead screw nut 132 is disposed on the second frame 11, the second frame 11 can be lifted relative to the first frame 10 as the lead screw nut 132 is lifted on the lead screw.

One end of the telescopic driving device 14 is hinged with the second frame 11, the disc brush assembly 12 is hinged with the second frame 11, and the other end of the telescopic driving device 14 is hinged with the disc brush assembly 12. When the telescopic driving means 14 is extended in its own extension direction, the brush assembly 12 will rotate clockwise or counterclockwise with respect to the second frame 11 about its hinge axis with the second frame 11; when the telescopic drive means 14 is shortened in its own extension direction, the brush assembly 12 will rotate about its hinge axis with the second frame 11 in a counter-clockwise or clockwise direction with respect to the second frame 11.
That is, the cleaning range of the brush assembly 12 can be increased to some extent by the extension and contraction of the extension and contraction driving device 14. When the number of the disc brush assemblies 12 is two and a telescopic driving device 14 is connected between each disc brush assembly 12 and the second frame 11, the included angle between the two groups of disc brush assemblies 12 can be adjusted, so that the adaptability of the cleaning disc brush mechanism 1 to different road surface widths can be improved.
