Description

Technical Field

[0001] The present invention relates to the technical field of snowplows, and in particular to a driving device for driving a snow guide chute of a snowplow to rotate. Background Art

[0002] Since the angle of the snow guide trough needs to be adjusted frequently during the operation of the snowplow, the snow guide trough needs to be constantly rotated. The transmission of the snow guide trough and the motor in the prior art mostly adopts chain transmission, and this transmission method has the following problems: the outer side of the chain is easily frozen in an extremely cold environment, resulting in the snowplow being unable to operate; on the other hand, in the rotating mechanism with chain transmission, the connection between the snow guide trough and the transition trough is mostly tightened by a pressure plate, and there is a gap between the pressure plate and the transition trough or the pressure is too tight, so the snow guide trough is prone to large vibrations or uneven rotation or even failure to rotate during the snow throwing operation. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a snow guide chute rotating mechanism for a snowplow, which can solve the problems in the prior art that the chain is easily frozen in an extremely cold environment, causing the snowplow to be unable to operate, and the snow guide chute is prone to produce large vibrations or rotate unsmoothly or even cannot rotate during the snow throwing operation.

[0004] In order to solve the above problems, the technical solution of the present invention is: the snow guide trough rotating mechanism of the snowplow includes a snow guide trough, a transition trough, a driving gear, a hydraulic motor and a slewing bearing; the transition trough is fixed on the snowplow body; the inner ring diameter of the slewing bearing is larger than the inner ring diameter of the transition trough; the inner ring of the slewing bearing is fixedly connected to the transition trough, the outer ring of the slewing bearing is fixedly connected to the snow guide trough, and the outer side of the outer ring of the slewing bearing is an external gear; the hydraulic motor base is fixedly installed on the transition trough, the hydraulic motor shaft is connected to the driving gear, and the driving gear is meshed with the external gear of the outer ring of the slewing bearing, so that the outer ring of the slewing bearing and the snow guide trough rotate together, thereby realizing the relative rotation of the snow guide trough and the transition trough and then throwing the snow to different angles.

[0005] In the above technical solution, a more specific solution is: the inner ring of the slewing bearing is fixedly connected to the transition groove by bolts.

[0006] Furthermore: the outer ring of the slewing bearing is fixedly connected to the snow guide groove by bolts.

[0007] Furthermore: the hydraulic motor drives the gear to rotate through hydraulic power.

[0008] Furthermore: the specification model of the hydraulic motor is: 160CC cycloidal motor.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention adopts a transition trough to be fixed on the vehicle, the snow guide trough is fixed to the outer ring of the slewing bearing by bolts, the inner ring of the slewing bearing is fixed to the transition trough by bolts, the hydraulic motor is fixed to the transition trough, and the motor drives the gear to rotate through the hydraulic pump, so that the outer ring of the slewing bearing and the snow guide trough rotate together, thereby realizing the relative rotation of the snow guide trough and the transition trough, thereby solving the problems existing in the prior art that the chain is easily frozen in an extremely cold environment, resulting in the inability of the snowplow to operate, and the snow guide trough is prone to produce large vibrations or rotates unsmoothly or even cannot rotate during the snow throwing operation.
