[0008] Preferably, a cleaning door is provided on the other side wall of the dust box.

[0009] Preferably, the tip of the scraper is close to the transmission belt.

[0010] Preferably, the filter is fixed to the input end of the suction fan by threads, and the filter can be removed by screwing.

[0011] Beneficial Effects

[0012] The utility model provides a special blade base for a sweeper. The utility model is designed with a structure for adjusting the position of the scraper and dust removal. First, the position of the bottom plate is fixed by bolts, and the impurities on the belt can be cleaned. The spring is always in a compressed state. When there are harder impurities, the scraper will be impacted by force to drive the connecting plate to move down, causing the spring to contract. Then the spring rebounds and drives the scraper to reset. The suction fan is started to suck dust and impurities into the dust box. The filter is used to block dust. When the belt does not need to be cleaned, the adjustment motor will drive the scraper away from the belt. The device can be used to clean the belt regularly. When it is not cleaned, the scraper can be adjusted away from the belt without complicated disassembly, which protects the scraper and has a dust removal effect to prevent the dust on the belt from affecting the surrounding air quality.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0022] Embodiment: First, fix the position of the base plate 1 by bolts, then start the motor 3 to drive the threaded rod 4 to rotate, and the rotation of the threaded rod 4 drives the lifting plate 5 to slide in the slot 6, which has a limiting effect. When the lifting plate 5 is adjusted to the uppermost position, the scraper 15 is closest to the belt, and the impurities on the belt can be cleaned. The spring 9 is always in a compressed state. When there are harder impurities, the scraper 15 will be impacted by force to drive the connecting plate 11 to move downward, causing the spring 9 to contract. Then the spring 9 rebounds and drives the scraper to reset. Since the elastic force of the spring 9 is sufficient, there will be no repeated rebound vibration. Start the suction fan 20 to suck dust and impurities into the dust box 18 through the diffusion dust suction port 16 and the connecting pipe 17, and use the filter 19 to block dust. After the dust removal is completed, open the cleaning door for cleaning. When the belt does not need to be cleaned, adjust the motor 3 to drive the scraper 15 away from the belt.
