Dry and wet two-purpose road sweeper

Abstract

The invention relates to a dry-wet dual purpose road sweeper, which comprises a vehicle frame as well as an auxiliary engine, a garbage bin, a suction fan, a chuck and dust removers which are arranged on the vehicle frame, wherein the chuck is arranged at the lower part of the vehicle frame and is connected to a garbage inlet of the garbage bin through a suction tube, the suction fan is connected with an air outlet of the garbage bin through an air duct, an air vent of the suction fan is connected with the dust removers, the auxiliary engine drives the suction fan, the suction fan is a double suction fan which is respectively communicated with the wet type diagonal flow dust removers. The road sweeper remedies the disadvantages that a suction sweeping road sweeper widely used on the market fails to be normally used in winter and is easy to spray ash and fly dust, and a suction road sweeper fails to perform wet operation and has poor sweeping efficiency and high use cost. The dry-wet dual purpose road sweeper uses a technology that the dry operation and the wet operation can both be performed, the design of the double suction fan with ultra-strong suction, and a unique wet type diagonal flow dust removal technology, and is the all-weather road sweeper.

Description

technical field [0001] The invention relates to a road sweeper, in particular to a wet and dry road sweeper which is suitable for any environment, has high cleaning efficiency, is convenient to operate, and is environmentally friendly. Background technique [0002] With the development of my country's economy and the needs of urbanization construction, mechanized cleaning of urban roads has been basically popularized. At present, there are three types of urban road sweepers on the market: ①, pure sweeping type; ②, sweeping suction type; ③ , Pure suction type. The pure-sweeping road sweeper does not use fan suction, but only relies on side sweeping brushes and roller brushes to sweep up the garbage and drop it into the garbage bin. The work efficiency is low, and it is easy to raise dust. be widely promoted. Sweeping suction road sweeping vehicles are mostly equipped with four brushes in the middle and a rear suction cup structure. During the cleaning process, wet dust contr...

AI Technical Summary

Problems solved by technology

At present, the pure suction road sweeper technology also has certain defects. Since the road sweeper does not need sweeping brushes, the suction of a fan is limited, and it is equipped with two suction nozzles that move with the car. 1. Dust, leaves, paper scraps and heavy particle garbage that adhere to the ground after raining are not easy to be sucked up. In addition, the suction cup is too wide (generally as wide as the vehicle body) to reduce the suction dispersion, so that the stones and sand on the road are sucked. It is not clean and there is spillage. In addition, the suction cup can only move up and down in a straight line, and the width of the suction sweep does not change, which affects the cleaning efficiency. Filtration of dusty airflow

However, due to complex road conditions, wet dust often passes through the cloth bag or filter paper device in case of rainy and snowy weather or road surface water, causing blockage of cloth holes or filter paper pores, increasing the operating resistance of the fan, reducing suction, and seriously reducing the quality of cleaning operations.

In order to ensure the quality of the operation, the filter device needs to be replaced and cleaned frequently in time, which increases the labor intensity of the operator, and the recycling rate of the cloth bag or filter paper is low, which leads to an increase in the cost of use. Dry dust and garbage, the raised fine powder dust will cause a wide range of air pollution, and cause great harm to the health of operators and surrounding residents
