Abstract
Description
Technical Field
[0001] This invention relates to the field of environmentally friendly road dredging, specifically a new type of environmentally friendly dredging vehicle for municipal roads. Background Technology
[0002] With social development, more and more roads are being built. Road environmental sludge removal vehicles are a type of environmentally friendly sanitation vehicle specifically designed to remove silt, dirt, oil, mud, and dust from road surfaces. Existing road surface structures include asphalt, concrete, paved bricks, and gravel roads. These road surfaces are prone to accumulating dust and dirt, have poor water permeability and air permeability, and poor wear resistance. Road surfaces with good wear resistance have poor drainage. Due to daily rainfall, when there is a large amount of water, water easily accumulates on the road. After the water recedes, a layer of silt forms on the ground, which affects daily traffic and poses a significant safety hazard.
[0003] The current method of treating sludge mainly relies on sanitation workers to clean it up. Manual cleaning is inefficient and labor-intensive. In addition, many sludge dredging devices use a bucket-type design to scoop up sludge. However, this design is not very effective in actual use because the sludge usually stays in depressions along the roadside and is relatively thin, making it difficult to scoop up. Furthermore, after the sludge is mixed with sewage and enters the dredging vehicle, it cannot undergo sufficient solid-liquid separation, resulting in a large amount of water mixed in with the sludge and wasting a significant amount of storage space. Summary of the Invention
