Sweeper brush arm anti-collision device

Abstract

The utility model discloses an anti-collision device for a sweeping brush arm of a sweeping vehicle, comprising a support and a sweeping brush; an anti-collision disc is arranged on the upper part of the sweeping brush, a disc seat is fixedly arranged on the anti-collision disc, and a driving motor for driving the sweeping brush to rotate is installed on the disc seat; the utility model also comprises a left swing arm and a right swing arm, the support, the left swing arm, the right swing arm and the disc seat are connected by a pin shaft, and the left swing arm, the right swing arm and the disc seat are arranged to rotate around the pin shaft; a reset spring is connected between the left swing arm and the right swing arm. The utility model has an ingenious structural design. When the anti-collision disc or the sweeping brush collides with a curbstone, under the action of the collision force, the anti-collision disc will drive the motor, the left swing arm and the right swing arm to rotate around the pin shaft, thereby avoiding deformation and damage of the sweeping brush arm due to the collision; when the collision force gradually decreases to disappear, under the pulling force of the reset spring, the left swing arm and the right swing arm drive the anti-collision disc and the sweeping brush to return to their original working positions, thereby ensuring the cleaning effect.

Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, in particular to an anti-collision device for a sweeping brush arm of a sweeper. Background Art

[0002] The sweeper is suitable for use in schools, hospitals, communities and other places. It does not raise dust and has low noise when sweeping. It can move flexibly among the crowd. It has a light structure, is portable and easy to maintain. The sweeping arm of the existing sweeper does not have an anti-collision structure. When the sweeper is sweeping both sides of the road, it collides with rocks or large stones on the roadside, which easily causes deformation of the sweeping arm and damage to the motor, and the sweeping effect of the sweeper is significantly reduced. Utility Model Content

[0005] As a preferred technical solution, the support includes a support body, and the side of the support body is provided with an upper fixing ear and a lower fixing ear, and the upper fixing ear and the lower fixing ear are respectively provided with pin holes.

[0006] As a preferred technical solution, the disc seat comprises a disc seat body, and an upper connecting ear and a lower connecting ear are arranged on the side of the disc seat body, and pin holes are respectively opened on the upper connecting ear and the lower connecting ear.

[0007] As a preferred technical solution, two spring seats are respectively provided on the left swing arm and the right swing arm, and return springs are respectively connected between the spring seats on the left and right sides.

[0008] Due to the adoption of the above-mentioned technical scheme, the utility model has at least the following beneficial effects: when the anti-collision plate or the sweeping brush collides with the curbstone, under the action of this collision force, the anti-collision plate will drive the motor, the left swing arm and the right swing arm to rotate around the pin shaft, thereby avoiding deformation and damage of the sweeping brush arm due to the collision; when this collision force gradually decreases to disappear, under the tension of the reset spring, the left swing arm and the right swing arm drive the anti-collision plate and the sweeping brush to return to their original working positions, thereby ensuring the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The following drawings are only intended to illustrate and explain the present invention, and do not limit the scope of the present invention.

[0012] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0013] like Figure 1 and Figure 2 As shown, the anti-collision device for the sweeping brush arm of a sweeping vehicle comprises a support 1 and a sweeping brush 2, and the device can be installed on the frame of the sweeping vehicle through the support 1; an anti-collision plate 3 is arranged on the upper part of the sweeping brush 2, and a disc seat 4 is fixedly arranged on the anti-collision plate 3, and a driving motor 5 for driving the sweeping brush 2 to rotate is installed on the disc seat 4; it also includes a left swing arm 6 and a right swing arm 7, and the support 1, the left swing arm 6, the right swing arm 7 and the disc seat 4 are connected by a pin shaft 8, and the left swing arm 6, the right swing arm 7 and the disc seat 4 can rotate around the pin shaft 8; a return spring 9 is connected between the left swing arm 6 and the right swing arm 7.

[0014] refer to Figure 2 In this embodiment, the support 1 includes a support body 11, and the side of the support body 11 is provided with an upper fixing ear 12 and a lower fixing ear 13, and the upper fixing ear 12 and the lower fixing ear 13 are respectively provided with a pin hole 14 for the pin shaft 8 to pass through.
