Technical Field

The invention relates to the technical field of snow removing equipment manufacturing, in particular to a rotating device for a rolling brush of a snow throwing vehicle.

Background

In the engineering machinery industry, a slewing device is often applied, and the existing slewing mechanism device technology mostly adopts a slewing device of which a hydraulic motor drives a gear ring assembly to slew. The invention provides a rolling brush rotating device which is arranged on a rolling brush of snow removing equipment, and the rolling brush swinging function is often used when a snow throwing vehicle passes through a curve in the road snow removing process in winter. In addition, the snow throwing vehicle adopts the rolling brush swinging function during operation, and can sweep snow to one side. The design of a rotating device involved in realizing the swing function of the rolling brush is a key technology.

Disclosure of Invention

The invention aims to solve the technical problem of providing a rolling brush rotating device of a snow throwing vehicle, which can conveniently utilize the swinging function of a rolling brush when the snow throwing vehicle passes through a curve and works, and can stably turn and sweep accumulated snow to one side as required.

In order to solve the problems, the technical scheme of the invention is as follows: the rolling brush rotating device of the snow throwing vehicle comprises a hanger bracket fixedly connected with a rolling brush on the snow throwing vehicle and an upper fixing frame fixed on a vehicle body of the snow throwing vehicle; the rack bracket is provided with an inner rotating ring, and the fixed frame is provided with an outer rotating ring; the inner rotating ring is sleeved in the outer rotating ring; the same side of the fixed frame is hinged with one ends of the left swing oil cylinder and the right swing oil cylinder at intervals in parallel; the other ends of the left swing oil cylinder and the right swing oil cylinder are hinged with the inner rotating ring, and the inner rotating ring and the outer rotating ring rotate relatively through the stretching of the left swing oil cylinder and the right swing oil cylinder.

In the above technical solution, a more specific solution is: the specifications and the models of the left swing oil cylinder and the right swing oil cylinder are the same.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

1. the rolling brush can realize the swinging function of the rolling brush, so that the rolling brush can sweep the accumulated snow to one side as required.

2. Compared with a slewing device for driving the gear ring assembly to slew by a hydraulic motor, the hydraulic motor-driven slewing device has the advantages of simple structure, long service life, convenience in maintenance and improvement on the working efficiency of the snow remover. The invention has simple production and manufacturing process. The manufacturing cost is lower.

3. the invention has smart design and more compact arrangement.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

The snowplow drum brush rotation device of figures 1-6,

comprises a hanger bracket 1, two swing oil cylinders, an inner rotating ring 3 and an outer rotating ring 4 fixedly connected in a fixed frame 5. The hanger bracket 1 is connected with a rolling brush on the snow throwing vehicle through a bolt; the two swing oil cylinders, namely the right swing oil cylinder 2 and the left swing oil cylinder 6, have the same specification and model, the cylinder bodies of the two swing oil cylinders are hinged with the same side of the fixed frame 5 side by side, and the piston rods of the two swing oil cylinders are hinged with the ring top surface of the inner rotating ring 3 relatively side by side; the rotation of the inner rotating ring 3 is controlled by the expansion of the piston rods of the two oil cylinders, and the bottom surface of the inner rotating ring 3 is connected with the hanger bracket 1 through a bolt; the outer rotating ring 4 is connected with the fixed frame 5 through a bolt, and the inner rotating ring 3 is sleeved in the outer rotating ring 4 and can rotate relative to the outer rotating ring 4, as shown in fig. 2 and 3; the fixed frame 5 is fixed to the vehicle body by bolts.

when the invention is used, as shown in fig. 4, when the left-right swinging oil cylinder is in the middle position, the inner rotating ring 3, the hanger bracket 1 and the outer rotating ring 4 do not rotate relatively, and the rolling brush rotating device does not swing; as shown in fig. 5, when the right swing cylinder 2 extends out and the left swing cylinder 6 contracts, the inner swivel 3 and the hanger bracket 1 rotate clockwise relative to the outer swivel 4, and the rolling brush connected with the hanger bracket 1 swings to a certain angle leftwards along with the hanger bracket 1; as shown in fig. 6, when the right swing cylinder 2 is retracted and the left swing cylinder is extended, the inner swivel ring 3 and the hanger bracket 1 rotate counterclockwise relative to the outer swivel ring 4, and the roller brush connected to the hanger bracket 1 swings to a certain angle to the right along with the hanger bracket 1. Therefore, the accumulated snow can be swept to a required side through the extension and retraction of the left-right swinging oil cylinder.
