A flexible and extended road sweeper

Abstract

The invention discloses a flexibly extended road sweeper, and belongs to the technical field of sanitation. The flexibly extended road sweeper comprises a main vehicle, wherein a main water tank for supplying water to a vehicle head splashing mechanism is arranged in the main vehicle; one or more extension units are butted with the rear end of a main vehicle chassis of the main vehicle; each extension unit comprises a reserve water tank, a base for supporting the reserve water tank, a butting base, a connecting pin, a supporting wheel, a height adjusting assembly capable of adjusting the height of the supporting wheel above the ground, and a pair of bottom wheels for supporting the reserve water tank; the upper end of each connecting pin is vertically inserted in the front end of the corresponding butting base, and the lower end of each connecting pin is rotatably and detachably inserted in the main vehicle chassis; a water pump is arranged on the main vehicle; each expansion unit is also provided with an access water pipe; the suction end of the water pump communicates with the reserve water tanks through the corresponding access water pipes, and the discharge end of the water pump communicates with the main water tank. According to the flexibly extended road sweeper disclosed by the invention, the volume of the sweeping water in the sweeper can be increased, the sweeping time of the sweeper is prolonged, and the frequency of refilling water is reduced.

Description

technical field [0001] The invention relates to the technical field of sanitation, in particular to a mobile road cleaning device. Background technique [0002] Mobile road sweeping devices, commonly known as road sweepers, play an important role in sanitation projects. At present, the sweeping method of the road sweeper follows the traditional method of spraying combined with sweeping, that is, spraying water on the ground while the sweeping brush rotates at a high speed, so as to avoid flying dust. [0003] The original water spray mechanism was supplied by the main water tank. When the water in the main water tank was used up, the cleaning operation had to be stopped, and the road sweeper was driven back to the water supply station to replenish the water source, which resulted in the working time of the road sweeper and the mileage of one sweep. restricted. Contents of the invention [0004] The purpose of the present invention is to provide a flexible and extended ro...
