A main brush that rotates at high speed to sweep trash into the hopper,
Similarly, a side brush that rotates at high speed to sweep corner debris to the main brush side, and a vacuum that sucks dust blown up into the brush chamber by the main brush into the dust collection chamber provided at the rear of the car body and collects it in the filter (1) A guide plate is provided on the front side of the main brush for guiding the dust swept by the main brush to the rear side of the brush chamber.

(2) On the lower side of the dust collecting chamber, a hopper is provided for accommodating debris guided by the guide plate and sent from the brush chamber and dust blown off from the filter. Is configured to be detachable from the vehicle body.

(3) At the lower part of the entrance of the hopper leading to the above-mentioned brush chamber, a scraping plate for scraping dust in contact with the rotating main brush is directed toward the inside of the brush chamber while being inclined obliquely upward from below. To protrude.

[Action]

 Each of the above elements operates as follows.

The above-mentioned element (1) is provided in order to guide the dust swept from the floor or the road surface by the high-speed rotating main brush from the floor or the road surface toward the dust collecting chamber at the rear of the vehicle body by hitting the guide plate. Eliminates the need to provide a hopper for sweeping the vehicle, thereby reducing the overall length of the vehicle body by the amount of no hopper, making it easier to see ahead and reducing the turning radius, and improving driving operability. to enable.

In the element (2), among the refuse guided and sent by the guide plate, relatively large refuse is directly collected by a hopper provided below the dust collection chamber, and the suction force of the vacuum fan The dust collected in the filter by the filter is also collected in the above hopper by a shaking device or self-cleaning action. Therefore, it is extremely easy to dispose of the collected dust and dust by simply removing one hopper. Enable.

In the element (3), the scraping plate protruding from the lower entrance portion of the hopper comes into contact with the rotating main brush to scrape off dust attached to the main brush, and removes the scraped dust. The scraping plate itself serves as a guide and can be taken into the hopper.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
