One-cylinder driven sweeping vehicle sweeper brush sweeping and moving device

Abstract

The invention relates to and provides a one-cylinder driven sweeping vehicle sweeper brush sweeping and moving device. Rising, falling and swinging-out of a sweeper brush are driven by a thrust source ( an air cylinder or a hydraulic cylinder) so that falling and 90-degree swinging-out of the sweeper can be achieved. After a power source is withdrawn, the sweeper brush is taken back to a sweeping vehicle chassis immediately, the complexity of a system is reduced, the structure is simplified, and installation and maintenance are simpler and more convenient. According to obstacle avoidance of the design, an obstacle avoidance spring is installed between rods, and when encountering a large hard obstacle, a sweeper mechanism avoids the large hard obstacle automatically. After passing the obstacle, the sweeper mechanism recovers to be in the sweeping state again due to resilience of the spring, and the sweeping device is protected effectively. According to the sweeper ground touching angle, the sweeper brush is directly installed on a machine seat with a fixed angle, and manual adjustment is not needed.

Description

technical field [0001] The invention relates to a cleaning movement device for a road sweeper driven by a cylinder. Background technique [0002] At present, the lifting and swinging of the sweeping brush of the road sweeper are driven by two thrust sources (air cylinder or hydraulic cylinder), one thrust source (air cylinder or hydraulic cylinder) controls the lifting of the sweeping brush, and the other thrust source (air cylinder or hydraulic cylinder) controls The swinging action of the sweeping brush; the movement of one sweeping brush is driven by two thrust sources, which increases the complexity of the system and is more complicated in the installation structure, which brings inconvenience to the maintenance and replacement of components; the avoidance of the sweeping brush is connected by a spring The car body and rod are completed, which makes the spring occupy a lot of space, the overall structure is not very compact, and the timeliness is poor.
