The roller sweeping device includes a roller brush and a supporting shielding cover, and the position of the roller brush matches the suction port on the road sweeper. In the specific cleaning process, the roller brush of the road sweeper rotates to roll up the garbage on the ground and send it to the suction port, so that the rolled up garbage is sucked into the garbage bin of the road sweeper by the suction port; the existing roller sweeping device has the following shortcomings during use: 1. The height installation position of the roller brush is fixed, and it is used for a long time. The bristles on the roller brush will wear, which will affect the fit with the ground and further affect the cleaning effect.

The replacement frequency of the cleaning roller 2 can be reduced through adjustment, thereby reducing the cost of use. In addition, the cleaning roller 2 can be cleaned and dried from the top after use without being affected by obstructions, which is convenient for personnel to operate and improves work efficiency.

[0028] Working principle: When in use, the entire device can be connected to the sweeper by means of the connecting seat and the external bolts, and the sweeping roller 2 is aligned with the dust suction port on the sweeper. When cleaning, the hard bristles on the sweeping roller 2 are in contact with the ground. When cleaning, the driving motor 15 can be turned on, and the output shaft of the driving motor 15 drives the sweeping roller 2 to rotate to clean the ground. During the cleaning process, the sweeping roller 2 is shielded by the first shielding plate 16, the two first mounting plates 1, the second shielding plate 101 and the two elastic shielding cloths 3, which can effectively reduce the dust from splashing outwards.

[0029] After cleaning for a long time, the hard bristles will rub against the ground and wear will occur, so that the hard bristles cannot effectively fit with the ground. Therefore, after cleaning for a period of time, the two electric telescopic rods 5 can be controlled to open in the opposite direction through the synchronous control switch, and the output shaft of the electric telescopic rod 5 drives the corresponding connecting block 6 to move downward, and the connecting block 6 drives the corresponding moving rod 4 to move downward, and the two moving rods 4 simultaneously drive the cleaning roller 2 to move downward through the two first mounting plates 1. When the hard bristles on the cleaning roller 2 contact the ground again, the two electric telescopic rods 5 can be closed. The height position of the cleaning roller 2 can be adjusted so that the hard bristles can fit with the ground when the hard bristles are not in contact with the ground, thereby effectively reducing the replacement frequency of the cleaning roller 2, thereby reducing the cost of use, and the height position of the cleaning roller 2 can be adjusted so that after use, the two electric telescopic rods 5 can be started forward so that the cleaning roller 2 drives the hard bristles to separate upward from the ground, so as to avoid the friction between the hard bristles and the ground when not in use, thereby improving the flexibility of use;

[0030] After use, the cleaning roller 2 is raised upward by positively starting the two electric telescopic rods 5, and then the electromagnetic valve 12 and the water pump 10 on the left are opened. The water pump 10 extracts water from the water tank 9 through the suction head. The extracted water enters the rectangular tube 7 through the electromagnetic valve 12 and the three-way pipe 11 on the left in turn. The water in the rectangular tube 7 is sprayed onto the cleaning roller 2 through multiple pipe heads 8. At the same time, the driving motor 15 is turned on, and the driving motor 15 drives the cleaning roller 2 to rotate. The multiple pipe heads 8 spray and rinse the rotating cleaning roller 2. After rinsing, the water pump 10 and the electromagnetic valve 12 on the left are closed. And open the solenoid valve 12 and the hot air blower 13 on the right side, the hot air blower 13 draws external wind, and discharges the hot air into the rectangular tube 7 through the conical cover 14, the solenoid valve 12 on the right side and the three-way pipe 11 in sequence, and the hot air inside the rectangular tube 7 is blown out through multiple pipe heads 8 to blow the rotating cleaning roller 2. By blowing hot air to the cleaning roller 2 in coordination with the rotation of the cleaning roller 2 itself, the cleaning roller 2 can be dried, thereby achieving the effect of cleaning and drying the cleaning roller 2 from the top, which is not affected by obstructions and does not require personnel to flush from the bottom, which is convenient for personnel to operate and improves work efficiency.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
