[0023] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] The following is combined with Figure 1-3 The present invention is described in further detail.

[0025] The embodiment of the present invention discloses a snow sweeper.

[0026] Reference Figure 1-Figure 3 A snowplow includes a snowplow body, a snow-throwing barrel 1, a support plate 2 and a one-way locking member, wherein the support plate 2 is arranged on the snowplow body, the snow-throwing barrel 1 is rotatably arranged on the support plate 2, and a steering mechanism is arranged on the support plate 2, the steering mechanism is used to drive the snow-throwing barrel 1 to rotate, and the one-way locking member has a one-way locking portion, which is used to limit the one-way rotation of the snow-throwing barrel 1. By setting the one-way locking member, the one-way locking portion of the one-way locking member limits the one-way rotation of the snow-throwing barrel 1, thereby realizing the one-way locking, so that the power transmission can only be transmitted to the snow-throwing barrel 1 through the steering mechanism, but cannot be transmitted to the steering mechanism in the reverse direction through the snow-throwing barrel 1, thereby improving stability and safety.

[0027] A bottom cover 9 is provided on the support plate 2, a steering mechanism is provided on the bottom cover 9, a top cover 10 is provided on the bottom cover 9, and the steering mechanism is enclosed in a cavity formed between the top cover 10 and the bottom cover 9, so as to improve the sealing performance, prevent debris from entering the steering mechanism, and improve the appearance.

[0028] In this embodiment, the steering mechanism includes a driving gear 4 and a driven gear 5 meshing with the driving gear 4. The snow-throwing barrel 1 is provided with a fixed seat 6, which is rotatably arranged on the support plate 2. The driven gear 5 is fixedly arranged on the fixed seat 6. The driving gear 4 can be manipulated to drive the driven gear 5 to rotate and drive the snow-throwing barrel 1 to rotate through the fixed seat 6. Specifically, a fixed block 15 is provided on the support plate 2, and the driving gear 4 is rotatably arranged on the fixed block 15. The driving gear 4 and the driven gear 5 are both bevel gears, and the driving gear 4 and the driven gear 5 are meshed.

[0029] The snow-throwing cylinder 1 is a component for throwing or transferring snowflakes. The fixing seat 6 is a supporting structure of the snow-throwing cylinder 1, and is rotatably arranged on the supporting plate 2, allowing the snow-throwing cylinder 1 to rotate relative to the supporting plate 2. The fixing block 15 is arranged on the supporting plate 2, and is used to support and fix the driving gear 4 so that it can rotate stably. The supporting plate 2 is used to provide a supporting basis for the steering mechanism. The steering of the snow-throwing cylinder 1 is achieved through the meshing of the driving gear 4 and the driven gear 5, which realizes the precise control and steering function of the snow-throwing cylinder 1, and has a compact structure and high transmission efficiency.

[0030] Among them, there are many ways to drive the driving gear 4 to rotate, such as directly driving it through a motor, and driving the driving gear 4 to rotate through a transfer member. For example, the transfer member is an axis core, and the axis core is connected to the power end of the snowplow through a connecting assembly. The power end of the snowplow transmits power to the axis core to drive the axis core to rotate, and the axis core is engaged with the driving gear 4, thereby driving the driving gear 4 to rotate.

[0031] A connecting plate is provided at the back of the snow-throwing cylinder 1, a fixing seat 6 is provided on the connecting plate, a connecting portion 1 7 is provided on the fixing seat 6, a connecting portion 2 8 is provided on the locking seat, and the connecting portion 1 7 is clamped with the connecting portion 2 8. Specifically, the connecting portion 1 7 is a convex block integrally formed on the upper end surface of the fixing seat 6, the convex blocks are arranged on the fixing shaft 16 at intervals along the circumference of the fixing shaft 16, and the connecting portion 2 8 is a groove integrally formed on the locking seat, the groove and the convex block are mutually clamped to complete the power transmission, avoid the relative displacement between the fixing seat 6 and the locking seat, and improve the accuracy of the rotation.

[0032] In this embodiment, a support rod is provided at the bottom of the support plate 2, and the support plate is arranged on the snow sweeper body through the support rod.

[0033] In this embodiment, the one-way locking member is a locking torsion spring 3. A fixed shaft 16 is provided on the support plate 2, a fixed seat 6 is coaxially provided on the fixed shaft 16, a locking seat is provided on the fixed seat 6, a locking torsion spring 3 is coaxially provided on the fixed shaft 16, and a torsion arm of the locking torsion spring 3 is connected to the locking seat. In this embodiment, when the locking torsion spring 3 rotates in the forward direction (i.e., the driving gear 4 actively drives the driven gear 5 to rotate), the inner diameter of the locking torsion spring 3 becomes larger, and the friction between the inner side of the locking torsion spring 3 and the surface of the fixed shaft 16 disappears, so that the locking torsion spring 3 can rotate; when the locking torsion spring 3 rotates in the reverse direction (the driven gear 5 actively drives the driving gear 4 to rotate), the inner diameter of the locking torsion spring 3 becomes smaller, and the inner side of the locking torsion spring 3 and the surface of the fixed shaft 16 fit each other, so that the friction becomes larger, so that the locking torsion spring 3 cannot rotate, and a one-way locking is achieved, which has the following advantages:

[0034] Improved stability: It can prevent the snow-throwing barrel 1 from being unsmooth or stuck when tilted or vibrated, thereby ensuring the stability of rotation.

[0035] Reduce noise: During the adjustment process, it can effectively avoid and reduce the generation of noise and improve the user experience.

[0036] Enhanced safety: By locking the direction of the snow exit, the one-way locking mechanism helps prevent accidental rotation, thereby enhancing the safety of operation.

[0037] In summary, the present invention can significantly improve the operational stability of the snowplow, reduce noise and enhance safety.

[0038] The inner contour of the driven gear 5 is provided with a fixing plate 11, and the locking seat is provided with a fixing plate 2 12. A fixed chamber for the locking torsion spring 3 to twist is formed between the fixing plate 11, the fixing plate 2 12 and the fixed shaft 16. There is a gap between the fixing plate 11 and the fixing plate 2 12 along the circumferential direction, and the torsion arm of the locking torsion spring 3 is located in the gap.

[0039] A pressure cap 13 is provided on the top of the fixing plate 1 11 and the fixing plate 2 12 . The pressure cap 13 is used to confine the locking torsion spring 3 in the fixing chamber to improve the stability of the installation of the locking torsion spring 3 .

[0040] A gasket 14 is provided between the fixing seat 6 and the supporting plate 2. The gasket 14 can effectively prevent the parts from loosening and play a protective role to ensure the stability of the connection.
