Description

Technical Field

[0001] The utility model relates to the technical field of trailer towing accessories, and particularly relates to a road ice breaker. Background Art

[0002] In northern China, after rain or snow in winter, if the snow on the road surface is not cleared in time after melting or being rolled by vehicles, it is extremely easy to form surface ice. This kind of surface ice poses a great safety hazard to normal driving vehicles and is the main cause of vehicle collision accidents in winter.

[0003] Currently, to remove this kind of ice layer, the commonly used method is to use a forklift or an excavator to level the ground surface or vibrate and dig, forcing the ice layer to loosen, and then clean it layer by layer.

[0004] Through technological innovation, technicians in this field have creatively designed and disclosed a wheeled ice breaker. Its rollers are designed with teeth. When rolling, the weight of the vehicle body is used to squeeze the rollers, thereby realizing the destruction of the ice and snow road surface and providing guarantee for removing snow and ice on the road surface. However, when this kind of equipment is in operation, it still has technical drawbacks. Specifically, the ice breaking wheels of the existing ice breaking machinery are fixed. When rotating and moving, they can only move on a flat road surface. When encountering an uneven ground surface, they cannot adhere to the ground for thorough cleaning, which is likely to cause damage to the road surface. Moreover, the existing rollers are rigid and have poor buffering performance, and the blades are likely to be damaged when walking.

[0005] In view of the above-mentioned drawbacks in the prior art, as technicians in this industry, the technical problem to be solved urgently is: how to design a road ice breaking device through technological improvement to improve the drawbacks of the existing ice breaking device, such as incomplete cleaning and easy damage of the rolling wheels.

Detailed implementation mode

[0023] Referring to the figure shown, the utility model effectively realizes buffering on the road surface and avoids damage to the road surface and equipment caused by hard impact by adding a roller frame that can swing back and forth and has elastic shock absorption, driving the entire roller 3 to swing under the towing frame, and at the same time adopts a reinforcement structure to improve the running strength of the entire roller.

[0024] Embodiment 1:

[0025] As shown in the attached drawings, a road ice breaker includes a towing frame 1, on which a hinged drive seat 11 is provided. Square steels 12 are arranged at the front and rear corners at the top end inside the towing frame 1, and a top plate is arranged on the top surface. A plurality of support plates 14 are arranged on the left, right and inside of the towing frame 1. The above-mentioned various structures together form a reinforced frame structure with an open bottom end.

[0026] A plurality of roller frames 2 are symmetrically arranged at the front and rear of the bottom of the towing frame 1 and are hinged through lower hinge shafts 16. Each roller frame 2 is provided with a shock-absorbing spring 4 fixed between an elastic seat 21 and an upper hinge shaft 13 below the towing frame 1; the shock-absorbing spring 4 is inclined. Looking from the side, the shock-absorbing springs 4 on the plurality of roller frames 2 arranged symmetrically front and rear are designed in an inclined eight-shaped manner.

[0027] As Figure 6 、 7 shown, each roller frame 2 is provided with a top plate 20 of the roller frame and side plates on the left and right sides. An elastic seat 21 is arranged on the top plate 20 of the roller frame for fixing the shock-absorbing spring 4. Roller fixing seats 23 are arranged at the bottoms of the two side plates of the roller frame 2, and the roller 3 is hinged through the roller fixing seats 23. Each roller 3 includes a plurality of annular support discs 31, and a plurality of blades 32 on the periphery are fixed through the plurality of annular support discs 31. The plurality of blades 32 are radially and evenly distributed and fixed on the annular support discs 31.

[0028] With the above structural design, when the device is in operation and moving on a snow- or ice-covered road, several blades 32 on the rotating rollers 3 squeeze the road surface and cut the ice and snow on the road surface. When encountering a bumpy road surface, the front and rear roller frames 2 can freely float up and down and are cushioned by the shock-absorbing springs 4, which can adhere to the ground and effectively avoid hard impacts on the ground surface. Since the blades 32 on the outer diameter of each roller 3 are supported by several annular support plates 31, the overall support strength is improved and the rigidity of the rollers is enhanced. The above structure not only endows the device with rigidity but also has good shock-absorbing performance on uneven ground surfaces.

[0029] Further, as Figure 4 shown, several support plates 14 are provided below the towing frame 1 of the present utility model, and the support plates 14 are spaced apart to support and reinforce the entire towing frame 1, thereby improving the overall strength of the towing frame 1.

[0030] A positioning plate 15 is also provided at the lower part of the towing frame 1, and the positioning plate 15 is located between two rows of roller frames 2 arranged left and right. Since the front and rear shock-absorbing springs 4 always push the two rows of roller frames 2 to swing downward, the positioning plate 15 can limit the swinging direction of the two rows of roller frames 2 to prevent them from swinging downward disorderly and causing the front and rear rows of roller frames 2 to collide.

[0031] When the present utility model is placed on the ground surface and encounters an uneven road surface during walking, the two rows of roller frames 2 swing up and down and are likely to collide with the positioning plate 15. To prevent damage to the two rows of roller frames 2 caused by frequent collisions, a buffer block 22 is provided between the roller frame 2 and the positioning plate 15, and the buffer block 22 is fixed on the roller frame 2 or the positioning plate 15. In this embodiment, the buffer block 22 is fixedly attached to the roller frame 2. When the two rows of roller frames 2 that swing up and down touch the positioning plate 15, the buffer block 22 made of rubber can be used for buffering.

[0032] Further, the present utility model is designed with multiple independent roller frames 2. This structure is more flexible in swinging or obstacle avoidance when walking on the ground surface and is not overly cumbersome. To ensure that the multiple independent roller frames 2 operate independently and do not interfere with each other, several roller frames 2 are spaced apart, and a gap of more than 5 mm, usually designed to be 1 cm wide, is provided between adjacent roller frames 2.

[0033] In summary, with the above structural design, during the operation process, when the ground surface is uneven, the present utility model can swing up and down and adhere to the ground for buffering under the action of the shock-absorbing springs 4, avoiding frontal impacts on snow and ice on the ground surface, and preventing damage to the device when breaking ice while adhering to the ground; the rollers 3 are all fixed with several blades 32 on the periphery through several annular support plates 31, and several blades 32 are radially and evenly distributed and fixed on the annular support plates.

[0034] This structure improves the fixing strength of the blade and avoids blade damage during the rolling movement, making it an ideal road ice breaker.
