It can be widely used in arterial roads, municipal and airport roads, urban residential areas, parks and other road cleaning. , The road sweeper can not only clean up garbage, but also reduce and prevent traffic accidents. At present, domestic road cleaning machines can be roughly divided into two categories, one is suction sweeping and the other is pure sweeping.

This high-power exhaust fan forms a partial vacuum at the air inlet, and then uses the suction of the air to move the weight Lighter and bulky garbage is absorbed into the dustbin inside the cleaning machine. Suction-sweeping road cleaning machinery has some obvious disadvantages: First, the high-power exhaust fan has to rotate at high speed to maintain the suction of the air, which will consume a lot of fuel during the entire cleaning process, so The use cost of the suction-sweeping road sweeper is relatively high; in addition, the cleaning capacity is limited. During the cleaning process, the garbage on the road surface is completely absorbed into the internal garbage bin by the air suction formed by the exhaust fan. When the garbage is absorbed, it appears that the capacity is insufficient.

The working principle of the pure sweeping road sweeper is: the sweeping brushes on both sides of the vehicle sweep the garbage on the road to the middle of the vehicle, and push the garbage and dust to the conveyor under the action of the rear brush, and through the circular operation of the conveyor belt, The garbage is transported to the garbage bin to complete the road sweeping work. Compared with the suction sweeping road sweeper, this structure of the road sweeper saves the expensive exhaust fan, and the energy consumption and cost are relatively low, but the overall structure is more complicated. In addition, the volume of the dustbin of the existing pure-sweeping road sweeper is relatively small, and the existing structural configuration is difficult to expand the volume of the dustbin, so the cleaning efficiency is low. Therefore, it is an urgent problem for those skilled in the art to develop a pure sweeping road sweeper with low energy consumption and cost, simple structure and high cleaning efficiency.
