Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to a safety component for a snow sweeper auger. Background Technology

[0002] Winters in northern regions are cold and snowy, often causing blockages on highways, urban roads, rural roads, and around houses, making it impossible to drive normally and causing great inconvenience to drivers and pedestrians. To ensure unobstructed roads, it is necessary to clear snow in a timely manner. Currently, the main methods for snow removal are: manual snow removal, chemical solvent snow removal, and mechanical snow removal. Manual snow removal generally uses pushing, shoveling, and sweeping methods, which are time-consuming, labor-intensive, and inefficient, and are only suitable for small areas. Although chemical solvent snow removal is simple and convenient, the de-icing agents can chemically corrode the road surface, shortening the road's lifespan, and also causing serious pollution to the surrounding environment. Mechanical snow removal is currently the most effective snow removal method. It is not only fast and efficient, but also inexpensive and does not cause environmental pollution. Therefore, various small snow sweepers that are fast and economical have emerged and have been rapidly promoted and applied.

[0003] However, existing snowplows on the market still have many shortcomings: the connection and maintenance of the auger and transmission components of existing snowplows are relatively complicated, and most of the existing snowplows use an integrated assembly for the auger and transmission components, which is very inconvenient for assembly and maintenance. When the auger blades collide with stones under the snow, because the transmission components and auger are an integral structure, the huge impact force cannot be dissipated, which can cause the auger blades to deform, easily causing damage to the auger and transmission components, thus affecting the service life of the snowplow and its normal operating performance. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a safety component for a snow sweeper auger.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a snow sweeper auger safety component, including a main shaft and two sets of auger supports, a fixed sleeve is provided in the middle of the main shaft, a middle partition is provided in the middle of the fixed sleeve, and a snap-fit ​​sleeve is symmetrically provided on the left and right sides of the middle partition. The snap-fit ​​sleeves on the left and right sides are aligned with each other, and the side of the snap-fit ​​sleeve near the fixed sleeve is connected to the fixed sleeve as an integral structure. The snap-fit ​​sleeve includes an opening, which is arranged in the rotation direction of the main shaft. The auger support includes an auger sleeve, and a mounting ring is provided at the end of the auger sleeve near the fixed sleeve. The mounting ring is provided with multiple mounting seats, which are arranged in a circular array along the axis of the auger sleeve. Each mounting seat is provided with a breakable pin, and the end of the breakable pin in one of the mounting seats near the fixed sleeve is snapped into the snap-fit ​​sleeve.

[0006] Preferably, the remaining end of the easily broken pin near the fixed sleeve is fixed in the mounting base of the auger bracket.

[0007] Preferably, the breakable pin includes a core rod and an outer rubber coating layer, and an annular groove is formed in the middle of the core rod, the position of which corresponds to the gap between the snap-fit ​​sleeve and the mounting base.

[0008] Preferably, the outer rubber coating layer has grooves with multiple axes.

[0009] Preferably, the fixed sleeve, the auger sleeve and the main shaft are each provided with corresponding pin holes, and the corresponding pin holes are provided with pins for connection.

[0010] The beneficial effects of this utility model are as follows: By installing a fixed sleeve on the main shaft, and the sleeve is equipped with a snap-fit ​​sleeve, the auger bracket is connected to the snap-fit ​​sleeve through a specially designed easy-break pin. When the snow sweeper is working, if the auger blades suddenly hit a hard obstacle such as a rock, a huge reverse impact force will be generated. When this impact force is transmitted to the easy-break pin, this specially designed pin, which is a weak link, will break immediately, thereby instantly cutting off the power transmission path and preventing the impact force from continuing to be transmitted to the main shaft, gearbox and other core transmission components. This effectively avoids the expensive transmission system from being damaged due to overload.

[0011] To further improve maintenance efficiency, the auger support is also designed with multiple mounting seats, each pre-installed with spare easy-break pins of the same specifications. When the working pin breaks, the operator can quickly remove the broken part and insert the spare pin without tools, which greatly shortens downtime and ensures the continuity and convenience of equipment operation.

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: A safety component for a snowplow auger, such as Figures 1-3 As shown, the device includes a main shaft 1 and two sets of auger supports 16. A fixed sleeve 2 is provided in the middle of the main shaft 1. A middle partition 3 is provided in the middle of the fixed sleeve 2. A snap-fit ​​sleeve 4 is symmetrically provided on the left and right sides of the middle partition 3. The snap-fit ​​sleeves on the left and right sides are aligned with each other. The snap-fit ​​sleeve 4 is connected to the fixed sleeve 2 as an integral structure on the side of the fixed sleeve 2 near the fixed sleeve 2. The snap-fit ​​sleeve 4 includes an opening 5, which faces the rotation direction of the main shaft 1. The auger support 16 includes an auger sleeve 6. An installation ring 7 is provided at the end of the auger sleeve 6 near the fixed sleeve 2. Multiple installation seats 8 are provided on the installation ring 7. The multiple installation seats 8 are arranged in a circular array along the axis of the auger sleeve 6. Each installation seat 8 is provided with a breakable pin 9. The end of the breakable pin 9 in one of the installation seats 8 near the fixed sleeve 2 is snapped into the snap-fit ​​sleeve 4.

[0018] The remaining end of the easily broken pin 9 near the fixed sleeve 2 is fixed in the mounting base 8 of the auger bracket 16.

[0019] The easily broken pin 9 includes a core rod 10 and an outer rubber covering layer 11. An annular groove 12 is provided in the middle of the core rod 10. The position of the annular groove 12 corresponds to the gap between the snap sleeve 4 and the mounting base 8.

[0020] The outer rubber coating layer 11 has grooves 13 with multiple axes.

[0021] The principle of this invention is as follows: During operation, the main shaft 1 rotates under the drive of the transmission system, which in turn drives the auger blades fixed on the auger bracket 16 to rotate, thus completing the snow removal operation. During this process, if the blades accidentally hit hard objects such as stones, a strong reverse impact force will be generated instantly. This impact force is quickly transmitted to the easily broken pin 9. This pin structure is specially provided with an annular groove 13 as a weak point for stress concentration, which can break quickly under overload, thereby immediately interrupting the power transmission chain and preventing the impact energy from further spreading to the main shaft 1, gearbox and other core transmission components, effectively protecting the entire transmission system from damage.

[0022] To improve the maintainability of the equipment, the auger support frame has multiple mounting seats 8 evenly distributed around its circumference. Each seat is pre-installed with a spare easily broken pin 9 of uniform specification. When the pin breaks during operation, thanks to its unique opening 5 alignment structure and the rotatable design of the support frame, the operator can manually remove the broken part without the aid of any tools and quickly align and insert the spare pin to complete the replacement. This design significantly reduces the time required for equipment maintenance and ensures the efficiency and continuity of snow removal operations.

[0023] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
