Therefore, they should not be understood as limiting the scope of protection of the present application.
[0020] refer to Figures 1 to 3 As shown, the present application discloses a telescopic snow shovel, comprising a multi-section shovel body 1, a rotating frame 5, a contour frame 4 and a hanging bracket 6, casters 14 are provided on both sides of the bottom of the multi-section shovel body 1, the rear end of the multi-section shovel body 1 is rotatably connected to the rotating frame 5 with a first direction as a rotating axis, the rotating frame 5 and the contour frame 4 are rotatably connected with a second direction as a rotating axis, and the first direction is perpendicular to the second direction, the contour frame 4 is connected to the hanging bracket 6 through the connecting frame 3 and the lifting cylinder 7, and the hanging bracket 6 is fixed on the snow removal vehicle, wherein the multi-section shovel body 1 comprises a first shovel body 11, a second shovel body 12 and a third shovel body 13, and the first shovel body 11 and the third shovel body 13 are respectively slidably connected to the second shovel body 12.
[0021] Specifically, the second shovel body 12 is provided with a slideway 15 extending along its axial direction, the first shovel body 11 is connected to one end of the second shovel body 12 through the slideway 15, the third shovel body 13 is connected to the other end of the second shovel body 12 through the slideway 15, and a telescopic assembly 8 is provided between the first shovel body 11 and the third shovel body 13 and the second shovel body 12. The telescopic assembly 8 includes a first telescopic oil cylinder 81 connected between the first shovel body 11 and the second shovel body 12, and a second telescopic oil cylinder 82 connected between the third shovel body 13 and the second shovel body 12. The first telescopic oil cylinder 81 and the second telescopic oil cylinder 82 can control the horizontal movement distance of the second shovel body 12 and the third shovel body 13, so that the snow removal width of the telescopic snow shovel varies from 470 mm to 7050 mm. In the process of adjusting the snow removal width of the telescopic snow shovel, the caster 14 can play a guiding role, so that the second shovel body 12 and the third shovel body 13 can slide more smoothly; at the same time, the caster 14 also plays a supporting role, reducing the deformation of the first shovel body 11, the second shovel body 12 and the third shovel body 13 due to their own weight, reducing the wear between the multi-section shovel body 1 and the slide 15, and extending the service life of the telescopic snow shovel. The telescopic assembly 8 of this embodiment can adjust the snow removal width of the snow shovel according to the width of the road surface, effectively improving the adaptability of the snow shovel, and greatly improving the operating efficiency of the snow removal vehicle.
[0022] In some embodiments, the rear end of the multi-segment shovel body 1 is hinged to the rotating frame 5 through a steering pin 53 arranged along the first direction, and at least one swing cylinder 2 is connected between the multi-segment shovel body 1 and the bracket 6 to drive the multi-segment shovel body 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, which are respectively located on the left and right sides of the steering pin 53; 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 body 1. The two swing cylinders 2 cooperate to drive the multi-segment shovel body 1 to swing left and right around the steering pin 53. In this embodiment, the left and right swing angles of the multi-segment shovel body 1 are controlled within the range of ±32 degrees by the swing cylinder 2. This structure enables the snow shovel to adapt to different snow removal needs and improves the flexibility and accuracy of snow removal operations.
[0023] In some embodiments, the upper part of the rotating frame 5 is hinged to the contour frame 4 through a rotating shaft 51 arranged along a second direction. In this embodiment, the second direction is the front-rear axis direction of the snow shovel. There is a limit hole on the rotating frame 5. Preferably, the limit hole is an arc hole, and the center of the arc hole coincides with the center of the rotating shaft 51. The connecting shaft 52 on the rotating frame 5 is connected to the limit hole of the rotating frame 5 to limit the angle of the rotating frame 5 to swing up and down relative to the contour frame 4. When the rotating frame 5 rotates with the rotating shaft 51 as the center, the movement of the connecting shaft 52 in the limit hole is limited by the aperture of the limit hole, thereby limiting the maximum left and right swing angle of the rotating frame 5 relative to the contour frame 4. In this embodiment, the relative rotation angle of the rotating frame 5 and the contour frame 4 is controlled within the range of ±5 degrees by the limit hole. When the telescopic snow shovel encounters a road surface with a horizontal slope, the multi-section shovel body 1 can be tilted left and right within a certain angle, and can change synchronously with the ground, so that the shovel blade of the telescopic snow shovel can perfectly touch the ground, improve the efficiency of ice and snow removal, and avoid the phenomenon of incomplete removal.
[0024] In some embodiments, the connecting frame 3 includes an upper tripod 31 and a lower tripod 32. One end of the upper tripod 31 and the lower tripod 32 is hinged to the profiling frame 4 through a pin 61, and the other end is hinged to the hanger 6 through a pin 61. The lower tripod 32 is connected to the hanger 6 through a lifting cylinder 7. When the lifting cylinder 7 is extended and retracted, the multi-segment shovel body 1 is driven to rise and fall through the rotating frame 5 and the profiling frame 4, and then the height of the multi-segment shovel body 1 from the ground is adjusted, so that the multi-segment 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 remove snow, the multi-segment shovel body 1 on the road surface is raised to facilitate the movement and transfer of the snow removal vehicle. The upper tripod 31 and the lower tripod 32 are parallel to each other, so that the profiling frame 4, the upper tripod 31, the lower tripod 32 and the hanger 6 form a parallelogram structure. The parallelogram structure can effectively ensure that when the telescopic snow shovel is in the working state and the shutdown state, the profiling frame 4 and the hanger 6 always maintain a relatively parallel state, thereby preventing unnecessary stress from being generated inside the snow shovel.
[0025] In some embodiments, an oil cup is provided on the outside of the slide 15, and the oil outlet of the oil cup extends to the slide 15. Lubricating grease is added to the slide 15 through the oil cup, which can keep the slide 15 lubricated and effectively prevent the slide 15 from rusting and corroding.
[0026] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
