Sweeper driving system of street cleaner and street cleaner

Abstract

A sweeper driving system and a street cleaner comprising the same are disclosed. The sweeper driving system comprises an oil tank for storing hydraulic oil; a hydraulic motor for driving the sweeper of the street cleaner to clean; a hydraulic pump communicated with the oil tank and connected with an oil inlet of the hydraulic motor through an oil inlet channel, wherein the oil outlet of the hydraulic motor is communicated with the oil tank through an oil return channel; an overflow valve connected between the oil inlet channel and the oil return channel; the sweeper driving system further comprises an electric control flow control valve connected in the oil inlet channel in series; a controller connected electrically with the electric control flow control valve for adjusting the flow Q1 of the hydraulic oil flowing through the electric control flow control valve according to the steering speed V of the street cleaner which performs the cleaning operation. By means of the technical scheme, relevance between the rotary speed of the sweeper of the street cleaner and the steering speed of the street cleaner can be established to efficiently perform the cleaning operation according to the steering state of the street cleaner.

Description

technical field [0001] The invention relates to the field of road cleaning vehicles, more specifically, to a brush driving device of the road cleaning vehicle and the road cleaning vehicle. Background technique [0002] At present, in vast urban and rural areas, road cleaning vehicles are widely used in road cleaning operations. Existing road cleaning vehicles generally include a vehicle body and a cleaning device carried by the vehicle body. The cleaning device may include brushes driven by a brush driving system, and may also include sprinklers and the like. When the road cleaning vehicle is cleaning the road, the road cleaning vehicle drives on the road to be cleaned, and at the same time, the sweeping brush of the cleaning device rotates under the drive of the hydraulic drive system to clean the road. [0003] Figure 1 to Figure 3 The three traditional hydraulic brush drive systems of the road cleaning vehicle are represented respectively, and the three traditional hyd...

AI Technical Summary

Problems solved by technology

[0012] In other words, the main defect of the traditional hydraulic brush driving system of the road cleaning vehicle is that the rotation speed of the brush of the cleaning device cannot be related to the driving speed of the road cleaning vehicle, so that it cannot be efficiently driven according to the driving state of the road cleaning vehicle. Clean up

Affect the quality of work or cause the bristles of the brush to wear quickly, increasing the cost of use
