Adjustable elastic reset structure of edge brush of electric sweeper

Abstract

The invention discloses an adjustable elastic reset structure of an edge brush of an electric sweeper. The adjustable elastic reset structure comprises a frame, a motor, a connecting rod, angle pendulums, a four-bar mechanism, a power cylinder, a push rod, a gas spring, an angle seat and edge brushes. The angle pendulums and the angle seat are arranged at the symmetrical positions of the two longsides of the frame respectively, the angle pendulums and the angle seat are connected through the push rod; and the two angle pendulums are hinged to form a linkage mechanism through the connecting rod. One vertical edge of the four-bar mechanism is hinged to the frame by means of the angle seat, and the other vertical edge of the four-bar mechanism is connected with the edge brushes. The gas spring is arranged between the angle seat and the four connecting rods. The motor drives the connecting rod to axially move so as to drive the edge brushes connected with the two ends of the connecting rod to do left-right pendulum amplitude adjustment. The two ends of the power cylinder are hinged to two opposite corners of the four-bar mechanism to form an edge brush lifting adjustable structure. According to the structure, the utilization rate of the edge brushes is improved, and the cleaning quality can be improved. In addition, due to the fact that the edge brushes are unfolded outwards, thesweeping width can be increased, the hard contact probability of the side face of the sweeper and a road cliff can be remarkably reduced, and unnecessary touch is avoided.

Description

technical field [0001] The invention belongs to a technical solution in the technical field of environmental protection machinery. Specifically, the invention relates to a side brush installation structure of a sweeping machine, in particular to an adjustable elastic reset structure of a side brush of an electric sweeper. Background technique [0002] The side brush is one of the necessary devices for the sweeper, and it is mainly used for cleaning the ground at both ends of the roller brush. Usually, the side brush is positioned and installed on the front side of the sweeper, and its cleaning width exceeds the width of the fuselage. This structure makes full use of the side brush installed on the side to expand the cleaning range. The disadvantage is that the side brushes are connected by positioning. This rigid structure has certain limitations in function. First, the anti-collision ability is poor, and the second is that the position of the side brushes cannot be adjusted...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the side brush adopts positioning connection. This kind of rigid structure has certain limitations in function. The first is that the anti-collision ability is poor, and the other is that the position of the side brush cannot be adjusted as needed.

This defect requires workers to drive carefully during cleaning operations and avoid road cliffs and obstacles in time, otherwise, once a collision occurs, the side brush will be damaged

Another defect of the side brush positioning connection is that after the normal wear of the bristles of the side brush, the position compensation cannot be obtained in time, causing the side brush to be in the air. This situation directly reduces the cleaning efficiency of the ground, and even causes missed sweeping

In general, the fixedly installed side brush cannot fully meet the user's requirements, and the design needs to be further improved
