Parallel elevator mechanism of edge brush handle of sweeper

Abstract

The invention discloses a parallel elevator mechanism of an edge brush handle of a sweeper. The parallel elevator mechanism comprises the edge brush handle, a motor, a screw, a pulley, a wire rope, an electric push rod, oscillating bars and a bracket; the electric push rod and the bracket are fixedly connected below a car body; a parallelogram four-connecting rod mechanism is formed between the inclined bracket and the motor by the two oscillating bars which are equal in length, arranged in parallel and connected through a hinge; the screw is arranged on the oscillating bar at the upper position to adjust the distance from the edge brush handle to the ground; the wire rope connected with the oscillating bars is connected with the electric push rod via the pulley in a turning manner to form the parallel elevator mechanism of which the edge brush handle controls deformation of the four-connecting rod mechanism along with traction of the electric push rod, that is, the edge brush handle and a pavement are kept at a set angle no matter where the edge brush handle is in a travel range. The parallel elevator mechanism is simple in structure, convenient to use, reliable to elevate, small in wire brush abrasion and high in sweeping efficiency, and the edge brush handle directionally and quantitatively contacts the pavement.

Description

technical field [0001] The invention relates to a lifting mechanism for a side brush handle of a sweeping machine. Specifically, the invention relates to a parallel lifting mechanism for a side brush handle of a sweeping machine. Background technique [0002] The sweeper implements the function of cleaning the road surface through the coordinated movement of the configured main brush handle, side brush handle and side brush handle. The side brush handle and the side brush handle are rotary discs, which collect the rubbish on the contacted road surface into the cleaning range of the main brush handle in the middle through power-driven rotation, so as to achieve the purpose of cleaning. During the non-operating stage of the sweeper, under the action of the self-provided lifting mechanism, the main brush handle, side brush handle and side brush handle are separated from the road and stored to reduce load and wear. The combination angle between the end surface of the front brus...

Problems solved by technology

Since the lifting adjustment mechanism of the side brush handle in the prior art is an inclined rod lifting mechanism, the side brush handle swings up and down centered on the bottom end of the inclined rod during adjustment. In this structure, the included angles of the side brush handle relative to the road surface at different positions are not equal. , if the angle of adjustment is too small, the contact area between the brush wire of the side brush handle and the road surface will be too large, which will easily cause excessive wear of the brush wire

If the angle of adjustment is too large, the contact area between the brush filaments of the side brush handle and the road surface will be small, resulting in poor cleaning quality.

Generally speaking, the side brush handles in the prior art are easy to adjust up and down and easy to operate, but the contact angle between the side brush handle and the road surface is variable, and the cleaning effect is inconsistent
