[0032] refer to Figures 1 to 3As shown, this utility model discloses a telescopic snowplow, including a multi-segment snowplow body 1, a rotating frame 5, a contouring frame 4, and a hanging frame 6. The bottom sides of the multi-segment snowplow body 1 are provided with casters 14. The rear end of the multi-segment snowplow body 1 is rotatably connected to the rotating frame 5 with a first direction as the pivot. The rotating frame 5 and the contouring frame 4 are rotatably connected with a second direction as the pivot, and the first direction is perpendicular to the second direction. The contouring frame 4 is connected to the hanging frame 6 through a connecting frame 3 and a lifting cylinder 7. The hanging frame 6 is fixed on a snowplow vehicle. The multi-segment snowplow body 1 includes a first snowplow body 11, a second snowplow body 12, and a third snowplow body 13. The first snowplow body 11 and the third snowplow body 13 are slidably connected to the second snowplow body 12.

[0033] Specifically, the second shovel body 12 is provided with a slide rail 15 extending along its axial direction. The first shovel body 11 is connected to one end of the second shovel body 12 through the slide rail 15, and the third shovel body 13 is connected to the other end of the second shovel body 12 through the slide rail 15. Telescopic components 8 are provided between the first shovel body 11 and the third shovel body 13 and the second shovel body 12. The telescopic components 8 include a first telescopic cylinder 81 connected between the first shovel body 11 and the second shovel body 12, and a second telescopic cylinder 82 connected between the third shovel body 13 and the second shovel body 12. The first telescopic cylinder 81 and the second telescopic cylinder 82 can control the horizontal movement distance of the second shovel body 12 and the third shovel body 13, allowing the snow removal width of the telescopic snowplow to vary from 470mm to 7050mm. During the adjustment of the snow removal width of the telescopic snowplow, the casters 14 act as guides, allowing the second and third shovel bodies 12 and 13 to slide more smoothly. Simultaneously, the casters 14 also provide support, reducing deformation of the first, second, and third shovel bodies 11 and 13 due to their own weight, minimizing wear between the multiple shovel sections 1 and the track 15, and extending the service life of the telescopic snowplow. In this embodiment, the telescopic assembly 8 adjusts the snow removal width of the snowplow according to the road surface width, effectively improving the adaptability of the snowplow and significantly increasing the operational efficiency of snow removal vehicles.

[0034] In some embodiments, the rear end of the multi-segment shovel 1 is hinged to the rotating frame 5 via a steering pin 53 arranged along a first direction, and at least one swing cylinder 2 is connected between the multi-segment shovel 1 and the bracket 6 to drive the multi-segment shovel 1 to swing left and right around the steering pin 53. In this embodiment, the first direction is the vertical direction. Preferably, there are two swing cylinders 2, located on the left and right sides of the steering pin 53 respectively; the base of the swing cylinder 2 is fixed on the bracket 6, and the output end of the swing cylinder 2 is fixedly connected to the multi-segment shovel 1. The two swing cylinders 2 cooperate to drive the multi-segment shovel 1 to swing left and right around the steering pin 53. In this embodiment, the swing angle of the multi-segment shovel 1 is controlled within the range of ±32 degrees by the swing cylinders 2. This structure allows the snowplow to adapt to different snow removal needs, improving the flexibility and accuracy of snow removal operations.

[0035] In some embodiments, the upper part of the rotating frame 5 is hinged to the contour frame 4 via a rotating shaft 51 arranged along a second direction. In this embodiment, the second direction is the front-to-back axis direction of the snowplow. The rotating frame 5 has a limiting hole; preferably, the limiting hole is an arc-shaped hole, with its center coinciding with the center of the rotating shaft 51. A connecting shaft 52 on the rotating frame 5 is connected to the limiting hole to limit the angle of the rotating frame 5's vertical swing relative to the contour frame 4. When the rotating frame 5 rotates around the rotating shaft 51, the movement of the connecting shaft 52 in the limiting hole is restricted by the hole diameter, thereby limiting the maximum left-to-right swing angle of the rotating frame 5 relative to the contour frame 4. In this embodiment, the relative rotation angle between the rotating frame 5 and the contour frame 4 is controlled within ±5 degrees using the limiting hole. When the telescopic snowplow encounters a sloped road surface, the multiple sections of the shovel body 1 can tilt left and right within a certain angle, achieving synchronous changes with the ground, ensuring the telescopic snowplow blade makes perfect contact with the ground, improving snow removal efficiency, and preventing incomplete snow removal.

[0036] In some embodiments, the connecting frame 3 includes an upper triangular frame 31 and a lower triangular frame 32. One end of the upper triangular frame 31 and the lower triangular frame 32 are hinged to the contour frame 4 via a pin 61, and the other end is hinged to the hanging frame 6 via a pin 61. The lower triangular frame 32 is connected to the hanging frame 6 via a lifting cylinder 7. When the lifting cylinder 7 extends or retracts, it drives the multi-section shovel body 1 to rise or fall by rotating the frame 5 and the contour frame 4, thereby adjusting the height of the multi-section shovel body 1 from the ground. This ensures that the multi-section shovel body 1 is in contact with the ground when the snow removal equipment is working. When the snow removal equipment does not need to perform snow removal operations, the multi-section shovel body 1 on the road surface is raised to facilitate the movement and relocation of snow removal vehicles. The upper triangular frame 31 and the lower triangular frame 32 are parallel to each other, so that the contour frame 4, the upper triangular frame 31, the lower triangular frame 32, and the hanging frame 6 form a parallelogram structure. The parallelogram structure can effectively ensure that the contour frame 4 and the hanging frame 6 always remain relatively parallel when the telescopic snow shovel changes between the working state and the stationary state, preventing unnecessary stress from being generated inside the snow shovel.

[0037] In some embodiments, an oil cup is provided on the outer side of the slide 15, and the oil outlet of the oil cup extends to the slide 15. By adding lubricating grease to the slide 15 through the oil cup, the slide 15 can be kept lubricated and effectively prevented from rusting and corroding.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
