Technical Field
[0001] The utility model relates to the technical field of road cleaning devices, in particular to a high-efficiency front cleaning device for a road cleaning vehicle. Background Art
[0002] A road sweeper is one of the common sanitation equipment. It can quickly clean the road surface, so it is widely used in the cleaning of trunk roads, municipal and airport pavements, urban residential areas, parks, etc. During the use of current road sweepers, the brush part of the cleaning device is in long-term contact and friction with the ground, which causes the brush to wear quickly and thus affects the cleaning efficiency. When the brush is worn to a certain extent, only the brush part can be replaced, but in fact the brush still remains for a long time and has utilization value. Direct replacement will inevitably cause waste of resources. In this regard, this application specifically proposes an efficient front cleaning device for road sweepers to avoid frequent replacement of the brush part and ensure that the brush part can still work efficiently. Utility Model Content

The beneficial effect of the utility model is that when the present application is in use, the height adjustment device provided can drive the connecting sleeve to move vertically along the vertical axis, and then the mounting plate together with the cleaning plate will also move vertically, and the bristles on the cleaning plate will also move synchronously. When the bristles are worn out during long-term use and affect the cleaning effect, it is only necessary to rotate the screw of the height adjustment device clockwise to drive the connecting sleeve to move downward along the vertical axis, and then the mounting plate at the bottom of the connecting sleeve together with the cleaning plate and the brush will also move downward synchronously. The movement of the brush will compensate for the contact between the worn part and the ground, thereby ensuring that the brush part can still perform cleaning operations efficiently and avoiding frequent replacement of the brush part.

[0016] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.
[0017] Embodiment 1, the technical solution is that the beneficial effect of the utility model is: when the present application is in use, the height adjustment device 9 provided can drive the connecting sleeve 4 to move vertically along the vertical axis 3, and then the mounting plate 5 together with the cleaning plate 7 will also move vertically, and the bristles 8 on the cleaning plate 7 will also move synchronously. When the bristles 8 are worn during long-term use and affect the cleaning effect, it is only necessary to rotate the screw 13 of the height adjustment device 9 clockwise to drive the connecting sleeve 4 to move downward along the vertical axis 3, and then the mounting plate 5 at the bottom of the connecting sleeve 4 together with the cleaning plate 7 and the brush will also move downward synchronously. The movement of the brush will compensate for the contact between the worn part and the ground, thereby ensuring that the brush part can still perform cleaning operations efficiently and avoiding frequent replacement of the brush part. The driving device 11 provided in the present application can drive the pinion 10 to rotate through the large gear 12, thereby driving the cleaning plate 7 together with the bristles 8 to rotate, and the rotating bristles 8 can clean the ground. There is a difference in the number of teeth between the large gear 12 and the small gear 10. When the large gear 12 rotates to a smaller number of circles, it can drive the small gear 10 connected to the bristles 8 to rotate a larger number of circles, thereby ensuring the efficient operation of the bristles 8. The present application has a simple structure, is easy to use, and has strong practicality.
[0018] Embodiment 2, based on embodiment 1, specifically, the front cleaning device of the cleaning vehicle in the prior art is equipped with a lifting device to facilitate the cleaning device to contact or separate with the ground. The present application only requires welding the connecting rod 1 to the lifting device of the existing cleaning vehicle.
[0019] When cleaning, the present application starts the motor 19 on the connection disk 2, and the motor 19 drives the driving shaft 18 to rotate. The rotation of the driving shaft 18 will drive the vertical shaft 3 to rotate through the cooperation of the large gear 12 and the small gear 10. The rotation of the vertical shaft 3 will drive the installation disk 5 to rotate through the connecting sleeve 4. The rotation of the installation disk 5 will cause the cleaning disk 7 to rotate together with the bristles 8. The rotating bristles 8 can contact the ground to perform cleaning operations. Moreover, the large gear 12 can drive the bristles 8 to rotate more circles through the small gear 10 when the large gear 12 rotates a few circles, thereby greatly improving the working efficiency of the bristles 8.
[0020] The brush will wear out during long-term use and have limited contact with the ground, which will affect work efficiency. At this time, you only need to rotate the screw 13 of the height adjustment device 9 clockwise. A handwheel 14 is provided to facilitate the rotation of the screw 13. The clockwise rotation of the screw 13 will drive the connecting sleeve 4 through the lifting sleeve 15, and the connecting sleeve 4 is restricted by the vertical sliding connection of the guide groove 16 and the guide block 17. Therefore, the clockwise rotation of the screw 13 will drive the connecting sleeve 4 to move downward along the vertical axis 3, and then the mounting plate 5 together with the cleaning plate 7 and the bristles 8 will move downward synchronously. The downward movement of the brush will compensate for the worn part in contact with the ground, thereby ensuring cleaning efficiency.
[0021] Embodiment 3, based on embodiment 2, when the brush is worn to a certain extent and needs to be replaced, the bolt 6 can be unscrewed to remove the mounting plate 5 together with the bristles 8 for easy replacement.
