Special suction port for washing and sweeping vehicle

Abstract

The invention provides a special suction port for a washing and sweeping vehicle. Each traction frame comprises a crossbeam and a supporting truss. The top of each supporting truss is fixed to the washing and sweeping vehicle, the bottom of each supporting truss is hinged to one end of a rod-shaped traction arm, the other end of each traction arm is used for fixing a suction port body, a water spray pipe is fixed through the corresponding crossbeam, main suction ports are fixed to the positions, in front of each water spray pipe, on the two sides of the suction port body, walking trundles are fixed in front of and behind the suction port body, first avoidance rotary shafts are symmetrically and vertically arranged on the left side and the right side of the suction port body, supporting arms are fixed along the first avoidance rotary shafts, second avoidance rotary shafts are vertically arranged at the other ends of the supporting arms, one ends of square pipe swing arms are fixed in the radial direction of the second avoidance rotary shafts, side water suction ports are formed in the swing arms downwards, and the axial direction of side push oil cylinders is parallel to the second avoidance rotary shafts. Through side suction devices, the problems that the ground on the outer side of a vehicle body is not provided with the water suction ports, redundant water left after sanitation work is too much and is accumulated on the ground, and washing adsorption is not thorough are solved.

Description

technical field [0001] The invention relates to a special suction port for washing and sweeping vehicles. Background technique [0002] With the rapid development of cities, the cleaning requirements for urban roads are gradually increasing. The previous operation mode of road sweepers cannot meet the cleaning needs of urban roads. Therefore, the application of sweeper vehicles has become more and more extensive. The sweeper uses high-pressure water to wash the road surface, which can wash out the dust and dirt in the gaps in the road surface, and then collect it into the garbage bin through the water suction port. The road surface after washing is much cleaner than the ordinary swept road surface. The traditional sweeping car only has a suction port that does not exceed the width of the car body. During cleaning operations, there are only side brushes and high-pressure flushing functions on both sides of the car, and there is no suction port outside the car to absorb dirt. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a special suction port for washing and sweeping vehicles to solve the problem that there is no water suction port on the outside of the car body, and the remaining water after the cleaning and spraying operation is too much to deposit on the ground for cleaning and adsorption.
