Reverse blowing system of road sweeper and road sweeper

Abstract

The invention discloses a reverse blowing system of a road sweeper and the road sweeper. The reverse blowing system comprises a reverse blowing fan and a reverse blowing flow path, wherein an inlet of the reverse blowing fan communicates with atmosphere, and an outlet of the reverse blowing fan communicates with an inlet of the reverse blowing flow path; an outlet of the reverse blowing flow path communicates with reverse blowing interfaces, wherein the reverse blowing interfaces are arranged on a sucker of the road sweeper and communicate with an inner cavity of the sucker. Because the reverse blowing system adopts the reverse blowing fan which is independent of a centrifugal fan for sweeping, outside clean air is used for reverse blowing, and reversed blown air carrying dust from a dustbin cannot be directly exhausted to the atmosphere; therefore, secondary raising dust is reduced.

Description

technical field [0001] The invention relates to the field of sanitation machinery, in particular to a blowback system of a road sweeper and the road sweeper. Background technique [0002] In the field of sanitation machinery, the main working parts of road sweepers are centrifugal fans for cleaning, brushes and suction cups. The main working process of the road sweeper is as follows: During the driving and working process of the road sweeper, under the action of the sweeping brush, the dust and debris on the road surface are gathered near the suction cup, and at the same time, the centrifugal fan for cleaning is running at high speed, and in the dustbin High negative pressure is generated, and under the action of high negative pressure, dust and debris are sucked into the dustbin through the suction port of the suction cup. In order to improve the cleaning efficiency of the road sweeper and make the road surface be picked up more cleanly, single or multiple anti-air blowing...

AI Technical Summary

Problems solved by technology

[0005] 1. The dust brought into the cleaning centrifugal fan by the air flow will also be directly discharged to the atmosphere, causing secondary dust;

[0006] 2. If several reverse blowing pipes are drawn from the outlet of the centrifugal fan for cleaning and introduced into the suction cup at the same time, the amount of reverse blowing may be insufficient;

[0007] 3. The aerodynamic noise source generated inside the centrifugal fan for cleaning will directly spread to the outside through the blowback pipe, causing noise problems;

[0008] 4. To control the start and stop of reverse blowing and the air volume, the valve plate located at the outlet of the centrifugal fan for cleaning must be adjusted, which is inconvenient for the operator to perform this operation in the cab
