Description

Technical Field

[0001] The utility model relates to a component of a road sweeper, in particular to a garbage collection conveyor installed at the lower rear part of the road sweeper, belonging to the technical field of sanitation machinery and equipment. Background Art

[0002] The working process of the road sweeper currently on the market is: first, the side brush sweeps the garbage on the road inward to the range that the main brush can sweep, then the main brush sweeps the garbage to the front of the suction cup, and finally the suction cup continuously sucks the garbage swept by the main brush into the on-board garbage bin. The suction cup of the existing road sweeper uses negative pressure suction to transfer garbage. Due to the large differences in the size and weight of garbage on the road, in order to suck it cleanly, it needs to be equipped with a high-power fuel engine to drive the fan for suction, which is not conducive to controlling the power consumption and emissions of the whole vehicle.

[0003] To this end, we have developed a new type of road sweeper that uses a combination of roller brush and spiral conveying to convey garbage. It is equipped with a garbage cleaning head, a garbage rolling brush and a garbage collection conveyor at the bottom of the front, middle and rear parts of the vehicle body. During the driving process of the vehicle body, the garbage cleaning head rotates and sweeps the road and the curbs beside the vehicle body, and sweeps the garbage from the front side of the vehicle to the center line of the front of the vehicle. The garbage rolling brush then rolls and sweeps the road the vehicle passes and sweeps the garbage from the side of the bottom of the vehicle to the center line of the bottom of the vehicle. Finally, the garbage collection conveyor uses a combination of roller brush and spiral conveying to convey the garbage swept on the center line of the bottom of the vehicle upward to the vehicle-mounted garbage bin for collection. Since the road sweeper does not need to use negative pressure suction to convey garbage and completely uses batteries as power, it can effectively reduce the power consumption and emissions of the entire vehicle. The utility model is a garbage collection conveyor installed at the bottom of the rear of the road sweeper. Utility Model Content
