High-speed sweeper pre-cleaning device

Abstract

The invention relates to the technical field of sweeping vehicles, and specifically discloses a front cleaning device of a high-speed sweeping vehicle, comprising a mounting rod (100), one end of the mounting rod is provided with a support plate (101), and the middle part of the support plate is provided with A guide mechanism (200), the guide mechanism is equipped with a moving mechanism (300), the left and right swing mechanism (400) is movably connected with the left and right swing mechanism, and the up and down swing mechanism (500) is movably connected with the left and right swing mechanism , An angle adjustment mechanism (600) is movably connected to the up and down swing mechanism, and a cleaning mechanism (700) is connected to the angle adjustment mechanism. The invention not only has the characteristics of wide cleaning range, no potential safety hazard, good stability, good flexibility, not easy to be damaged, good accuracy and angle adjustment function.

Description

technical field [0001] The invention relates to the technical field of sweeping vehicles, in particular to a front cleaning device of a high-speed sweeping vehicle. Background technique [0002] Some of the existing cleaning vehicles will install a cleaning device on the front of the cleaning vehicle. The cleaning device is installed on the front base through a four-link structure. For cleaning, it is impossible to clean the left and right sides of the road at the same time, and the cleaning range is relatively small; due to the limitation of the width range of the vehicle, the four-link structure cannot be too long, otherwise it will bring safety hazards when the sweeper is working quickly, and it will also make The cleaning range is relatively small; the cleaning device connected by the four-link structure will jump when the specific cleaning vehicle is working quickly, which will affect the specific cleaning effect, and the stability is not very good, making the cleaning ...

Problems solved by technology

[0002] Some of the existing cleaning vehicles will install a cleaning device on the front of the cleaning vehicle. The cleaning device is installed on the front base through a four-link structure. For cleaning, it is impossible to clean the left and right sides of the road at the same time, and the cleaning range is relatively small; due to the limitation of the width range of the vehicle, the four-link structure cannot be too long, otherwise it will bring safety hazards when the sweeper is working quickly, and it will also make The cleaning range is relatively small; the cleaning device connected by the four-link structure will jump when the specific cleaning vehicle is working quickly, which will affect the specific cleaning effect, and the stability is not very good, making the cleaning unclean; the existing cleaning vehicles Once the front cleaning device is installed on the front of the sweeper, even if it is almost completely fixed, it can only clean in a small range, and cannot achieve cleaning in a larger area through swing adjustment; when cleaning The device collides with obstacles during cleaning, and it is almost a rigid collision. It cannot avoid the obstacles encountered, and it cannot return to its original position after avoiding the obstacles. The flexibility is also poor, which will damage the front cleaning. device or obstacle; the front cleaning device in the existing sweeping vehicle, with the continuous wear of the bristles on the sweeping disc, the pressure between the sweeping disc and the cleaning ground will become smaller, which will affect the specific cleaning effect. The best way is to install an inclined lifting cylinder on the four-link structure. When the bristles are found to be worn and the ground contact pressure becomes smaller, the four-link structure is rotated downward by controlling the extension length of the piston rod of the lifting cylinder, and then Increase the cleaning pressure between the sweeping disc and the ground. The problem is that the control of the ground contact pressure is too rough and cannot be accurate. It is small, but it cannot guarantee a good cleaning effect; the sweeping disc does not have an angle adjustment function, and can only clean the horizontal bottom surface. When encountering inclined ground or pits, the cleaning state cannot be adjusted according to the specific road conditions. , so that some places cannot be cleaned, and the flexibility is poor

[0003] Therefore, the front cleaning device in the existing cleaning vehicle has the problems of small cleaning range, potential safety hazard, poor stability, poor flexibility, easy damage, poor accuracy and no angle adjustment function.
