Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] Such as figure 1 and figure 2 As shown, one aspect of the present invention provides a road cleaning vehicle. The road cleaning vehicle includes a cab 80 and a garbage suction box 10 located behind the cab 80 . The front of the garbage suction box 10 is provided with a fan 30 . The air inlet of the blower fan 30 communicates with the garbage suction box 10, so that a suction negative pressure is formed in the garbage suction box 10, and the size of the suction negative pressure can be represented by the degree of vacuum. In order to improve energy utilization efficiency and adjust the rotating speed of fan 30 in a targeted manner, the road cleaning vehicle provided by the present invention is provided with a suction negative pressure detect...

Abstract

The invention provides a street cleaning vehicle and a rubbish sucking control method of the street cleaning vehicle. The street cleaning vehicle comprises a rubbish sucking tank body, a draught fan, a sucking negative-pressure detecting device, a driving device and a controller, wherein sucking negative pressure is formed in the rubbish sucking tank body through the draught fan, the sucking negative-pressure detecting device detects the actual sucking negative pressure in the rubbish sucking tank body or in the position of a suction nozzle of the rubbish sucking tank body, the driving device is provided with a power output end which is connected with the power input end of the draught fan, the controller judges whether the actual sucking negative pressure is equal to a preset sucking negative pressure, and if not, the rotating speed of the draught fan is adjusted so that the actual sucking negative pressure in the rubbish sucking tank body or in the position of the suction nozzle of the rubbish sucking tank body can be equal to the preset sucking negative pressure. By the adoption of the street cleaning vehicle, the actual sucking negative pressure in the rubbish sucking tank body or in the position of the suction nozzle of the rubbish sucking tank body is detected in real time, then judgment is conducted, and the rotating speed of the draught fan is adjusted, so that in the process of cleaning by the street cleaning vehicle, the output power of the draught fan can be selected according to the actual working conditions, and not only is the good cleaning effect achieved, but also energy waste is reduced.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a road cleaning vehicle and a garbage suction control method thereof. Background technique [0002] The ability of the road cleaning vehicle to absorb garbage is determined by the negative pressure (vacuum degree) of the garbage bin and the suction nozzle, and the vacuum degree in the garbage bin is determined by the fan speed. Ordinary road cleaning vehicles can only indirectly control the speed of the fan by adjusting the remote throttle of the engine. The degree of adjustment cannot be quantified. It can only rely on the operator's experience and feel, and the energy utilization efficiency is low. For example, when cleaning a section of road with a lot of rubbish, the operator increases the throttle (actual output power) to 95%, and the fan system works under heavy load, so that the dustbin system can generate a maximum vacuum of 70%. According to the actual ...
