Sweeping method and road cleaning vehicle

Abstract

The invention discloses a sweeping method and a road cleaning vehicle. The method comprises the steps of sweeping large particles on a road through hair (140) of a sweeping plate (100), wherein the hair (140) is in critical contact with the ground; brushing the ground through a water curtain of a high pressure nozzle (120); collecting sewage and garbage swept and brushed from the ground through an absorbing nozzle. According to the method, the water curtain is used for brushing the ground, so that dust can be lowered down effectively while sweeping; meanwhile, the large particles which cannot be removed by the water curtain can be removed through the hair which is in the critical contact with the ground, and therefore, the hair wearing can be reduced, and as a result, the cost can be saved.

Description

technical field [0001] The invention relates to the field of sanitation, in particular to a cleaning method and a road cleaning vehicle. Background technique [0002] Road cleaning vehicles (such as CN1865599A and JP4146774B) usually use sweeping discs to clean the road surface. Existing sweeping discs usually include a rotatable main body of the sweeping disc and bristles installed on the main body of the sweeping disc. The main body of the sweeping disc drives the bristles to rotate so that the bristles are in contact with the ground (the bristles are pressed against the ground, even deformation) and kick up the dust for collection. At the same time, the raised dust can be controlled by low-pressure water spray. When the operating speed of the road cleaning vehicle is not high, the sweeping disc does not raise a lot of dust due to the low rotation speed, and the dust reduction requirements can be met by using low-pressure water spray; but when the operating speed exceeds...

AI Technical Summary

Problems solved by technology

When the operating speed of the road cleaning vehicle is not high, the sweeping disc does not raise a lot of dust due to the low rotation speed, and the dust reduction requirements can be met by using low-pressure water spray; but when the operating speed exceeds 10km / h, in order to realize the road surface To carry out effective cleaning, the speed of the sweeping plate is required to be greatly increased. At this time, the dust raised by the sweeping plate will be very large, and the low-pressure spray cannot achieve the effect of dust reduction.

[0003] Therefore, there is a problem in the prior art that it is impossible to take into account the effective cleaning of the road surface during high-speed road sweeping and the problem of well controlling the dust during the sweeping operation.
