Description

TECHNICAL FIELD

[0001] The utility model relates to a snow removal vehicle technical field especially relates to a kind of driving device for driving snow removal vehicle snow guide groove rotation. BACKGROUND

[0002] Since snow removal vehicle operation process snow guide groove needs to be adjusted frequently snow guide groove angle, snow guide groove needs to be rotated constantly, the transmission of the snow guide groove and motor of prior art is more chain transmission, and this transmission mode has the following problems: chain is easily frozen in the outside under extremely cold environment, which leads to the snow removal vehicle unable to work;On the other hand, in the rotating mechanism of chain transmission, the connection between snow guide groove and transition groove is mostly by pressing plate, and there is a gap between pressing plate and transition groove or the pressing is too tight, which causes the snow guide groove to vibrate or rotate unevenly during snow throwing operation. SUMMARY

[0003] The utility model solves the technical problem that the chain is easily frozen in the outside under extremely cold environment, which leads to the snow removal vehicle unable to work and the snow guide groove to vibrate or rotate unevenly during snow throwing operation.

[0004] In order to solve the above problems, the technical scheme of the utility model is as follows: the snow removal vehicle snow guide groove rotating device includes a snow guide groove, a transition groove, a drive gear, a hydraulic motor and a slewing bearing;The inner ring of the slewing bearing is fixedly connected with the transition groove, the outer ring of the slewing bearing is fixedly connected with the snow guide groove, and the outer side of the outer ring of the slewing bearing is provided with an external gear;The hydraulic motor is fixedly installed on the transition groove, the rotating shaft of the hydraulic motor is connected with the drive gear, the drive gear is engaged 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 groove rotate together, and the relative rotation between the snow guide groove and the transition groove is realized, and the snow is thrown to different angles.

[0005] In the above technical scheme, the more specific scheme is that the inner ring of the slewing bearing is fixedly connected with the transition groove by bolts.

[0006] Further, the outer ring of the slewing bearing is fixedly connected with the snow guide groove by bolts.

[0007] Further, the hydraulic motor drives the gear to rotate by hydraulic power.

[0008] Further, the specification and model of the hydraulic motor are 160CC cycloid motor.

[0009] Compared with the prior art, the utility model has the following beneficial effects due to the adoption of the above technical scheme:

[0010] This invention employs a transition groove fixed to the vehicle. The snow guide groove is fixed to the outer ring of the slewing bearing by bolts, and the inner ring of the slewing bearing is fixed to the transition groove by bolts. The hydraulic motor is fixed to the transition groove. The motor drives the gear to rotate through the hydraulic pump, thereby causing the outer ring of the slewing bearing and the snow guide groove to rotate together. This achieves relative rotation between the snow guide groove and the transition groove, thus solving the problems of existing technologies where the chain easily freezes in extremely cold environments, making snowplows unable to operate, and the snow guide groove easily vibrates or rotates unevenly or even fails to rotate during snow throwing operations.

[0012] Figure 2 This is a structural assembly diagram of this utility model.

[0013] The numbers in the diagram are: 1-snow guide trough, 2-drive gear, 3-hydraulic motor, 4-slewing bearing, 5-transition groove, 6-bolt. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0015] Figure 1 and Figure 2 The snowplow's snow guide trough rotation device includes a snow guide trough 1, a drive gear 2, a hydraulic motor 3, a slewing bearing 4, and a transition groove 5. The transition groove 5 is fixed to the snowplow's body. The inner diameter of the slewing bearing 4 is larger than the inner diameter of the transition groove 5. The inner diameter of the slewing bearing 4 is fixedly connected to the transition groove 5 by bolts 6. The snow guide trough 1 is fixedly connected to the outer diameter of the slewing bearing 4 by bolts 6. An external gear is set on the outer side of the outer diameter of the slewing bearing 4. The base of the hydraulic motor 3 is fixedly installed on the transition groove 5. The shaft of the hydraulic motor 3 is connected to the drive gear 2. The hydraulic motor 3 drives the drive gear 2 to rotate via hydraulic power. The drive gear 2 meshes with the external gear on the outer diameter of the slewing bearing 4, causing the outer diameter of the slewing bearing 4 and the snow guide trough 1 to rotate together. This achieves relative rotation between the snow guide trough 1 and the transition groove 5, thus enabling the snow to be thrown at different angles. The hydraulic motor 3 is a 160CC cycloidal motor.
