[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered 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 utility model is described in further detail.

[0025] The embodiment of the utility model discloses a snow outlet steering assembly.

[0026] Reference Figure 1-Figure 3 The snow outlet steering assembly includes a snow barrel 1, a support plate 2 and a one-way locking member. The snow barrel 1 is rotatably arranged on the support plate 2. A steering mechanism is provided on the support plate 2. The steering mechanism is used to drive the snow barrel 1 to rotate. The one-way locking member has a one-way locking portion. The one-way locking portion is used to limit the one-way rotation of the snow barrel 1. By providing the one-way locking member, the one-way locking portion of the one-way locking member limits the one-way rotation of the snow barrel 1 to achieve one-way locking, so that power transmission can only be transmitted to the snow barrel 1 through the steering mechanism, rather than being transmitted back to the steering mechanism through the snow barrel 1, thereby improving stability and safety.

[0027] A bottom cover 9 is provided on the support plate 2, the 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, thereby improving the sealing, preventing debris from entering the steering mechanism, and improving 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 barrel 1 is provided with a fixed seat 6, which is rotatably provided on the support plate 2. The driven gear 5 is fixedly provided on the fixed seat 6. The driving gear 4 can be manipulated to drive the driven gear 5 to rotate through the fixed seat 6 to drive the snow barrel 1 to rotate. Specifically, a fixed block 15 is provided on the support plate 2, and the driving gear 4 is rotatably provided 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 barrel 1 is a component used to throw or transfer snowflakes. The fixed seat 6 serves as the support structure of the snow barrel 1 and is rotatably mounted on the support plate 2, allowing the snow barrel 1 to rotate relative to the support plate 2. The fixed block 15 is set on the support plate 2 to support and fix the driving gear 4 so that it can rotate stably. The support plate 2 is used to provide a supporting foundation for the steering mechanism. The steering of the snow barrel 1 is achieved through the meshing action of the driving gear 4 and the driven gear 5, realizing precise control and steering of the snow barrel 1. It 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 a shaft core, and the shaft core is connected to the power end of the snowplow through a connecting component. The power end of the snowplow transmits power to the shaft core to drive the shaft core to rotate, and the shaft core is engaged with the driving gear 4, thereby driving the driving gear 4 to rotate.

[0031] The back of the snow-throwing cylinder 1 is provided with a connecting plate, on which a fixing seat 6 is mounted. A connecting portion 1 7 is provided on the fixing seat 6, and a connecting portion 2 8 is provided on the locking seat. The connecting portion 1 7 and the connecting portion 2 8 are engaged with each other. Specifically, the connecting portion 1 7 is a protrusion integrally formed on the upper end surface of the fixing seat 6, and the protrusions are arranged on the fixing shaft 16 at intervals along the circumference of the fixing shaft 16. The connecting portion 2 8 is a groove integrally formed in the locking seat. The groove and the protrusion engage with each other to complete power transmission, prevent relative displacement between the fixing seat 6 and the locking seat, and improve rotation accuracy.

[0032] 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 arranged on the fixed shaft 16, a locking seat is provided on the fixed seat 6, and the locking torsion spring 3 is coaxially arranged on the fixed shaft 16. The 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 increases, and the friction between the inner side of the locking torsion spring 3 and the surface of the fixed shaft 16 disappears, thereby allowing rotation; 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 decreases, and the inner side of the locking torsion spring 3 and the surface of the fixed shaft 16 fit together, causing the friction to increase, thereby preventing rotation, achieving one-way locking, and having the following advantages:

[0033] Improved stability: It can prevent the snow-throwing tube 1 from being unsmooth or stuck when tilted or vibrated, thereby ensuring the stability of rotation.

[0034] Reduce noise: During the adjustment process, it can effectively avoid and reduce the generation of noise and improve the user experience.

[0035] 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.

[0036] In summary, the utility model can significantly improve the operational stability of the snowplow, reduce noise and enhance safety.

[0037] 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 torsion of the locking torsion spring 3 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.

[0038] 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 .

[0039] A gasket 14 is provided between the fixing seat 6 and the support plate 2. The gasket 14 can effectively prevent the components from becoming loose, and at the same time plays a protective role to ensure the stability of the connection.

[0040] In other embodiments, the steering mechanism may also be a belt and pulley, etc.

[0041] In other embodiments, the one-way locking member may also be a ratchet wheel.

[0042] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of the present utility model.
