[0002] With the development of the economy and society and the acceleration of urbanization, the impact of rainy and snowy weather in winter on people's travel is becoming increasingly significant, especially in areas with heavy snowfall. Airports and municipal sanitation departments need to frequently carry out snow removal operations to ensure smooth roads and traffic safety. Traditional snow shovels mostly use chain structures to remove snow by their own weight, but this method is easy to damage the road surface and the snow removal efficiency is not high.

[0003] In recent years, the emergence of four-link snowplows has provided a new solution for snow removal work. It can achieve horizontal deflection and lifting of the snowplow to avoid damage to the road surface. However, this improvement plan also has problems, that is, it abandons the adjustment function of the snow removal angle of the shovel body, resulting in the snowplow's application range being limited and unable to cope with snow removal operations in multiple scenarios.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] The utility model provides a multi-link snow removal shovel with adjustable snow removal angle, such as Figure 1-3 As shown, a multi-link snowplow with adjustable snow removal angle comprises: a rear connecting frame 1, which is composed of a plurality of connecting rods, and two deflection limiters 2 are symmetrically arranged on both sides of the rear connecting frame 1; a lower connecting frame 3, which is connected between the two deflection limiters, and an upper connecting frame 5, one end of which is hinged to the top of the lower connecting frame; a lifting cylinder 17, the piston rod of which is connected to the bottom of the upper tripod, and the base of which is connected to the rear connecting frame; a deflection hydraulic cylinder 4, which has two deflection hydraulic cylinders 4 and is hinged on both sides of the rear connecting frame; a shovel body 7, which is connected to the piston rod of the deflection hydraulic cylinder, and a detachable shovel blade 10 is arranged on the shovel body 7; and a heating mechanism for melting snow, which is arranged on the shovel body 7.

[0019] It should be noted that in recent years, with the increase in winter snowfall, the importance of snow removal has become increasingly prominent. Traditional snow removal methods often have problems such as low efficiency and great damage to the road surface. In response to these challenges, the four-link snow shovel has emerged as an innovative snow removal tool. With its unique horizontal deflection and lifting function, it effectively solves the problem of damage to the road surface and brings changes to snow removal work; the emergence of the four-link snow shovel has undoubtedly brought significant convenience to snow removal work. Through the sophisticated four-link mechanism design, the snow shovel can achieve horizontal deflection and lifting, so as to easily cope with snow accumulation at different heights. This design not only avoids the direct impact on the road surface in traditional snow removal methods, reduces damage to the road surface, but also improves the snow removal efficiency, making snow removal work more efficient and quick; however, although the four-link snow shovel has achieved remarkable results in avoiding road damage, it also has some shortcomings. Specifically, this improvement scheme abandons the adjustment function of the snow removal angle of the shovel body, which limits the scope of application of the snow shovel. In actual snow removal operations, the snow accumulation conditions in different scenarios are different, and different snow removal angles are required to achieve the best snow removal effect. However, due to the lack of adjustment function of snow removal angle, the four-link snowplow is often unable to adapt to these changes, resulting in poor snow removal effect or even failure to complete the snow removal task. In order to solve this problem, it is particularly important to further improve the design of the four-link snowplow;

[0020] In this embodiment, the rear connecting frame 1 is composed of a plurality of connecting rods, forming a stable supporting structure, providing a solid foundation for the entire snow shovel. The deflection limiters 2 are symmetrically arranged on both sides of the rear connecting frame 1, ensuring the stability and safety of the snow shovel during the deflection process, and preventing damage or accidents that may be caused by excessive deflection; the overall stability and safety of the snow shovel are enhanced, making the snow removal operation more reliable; the arrangement of the upper connecting frame 5 and the lower connecting frame 3, in conjunction with the articulation of the lifting cylinder 17, realizes the lifting function of the shovel body 7, and the upper connecting frame is connected to the shovel body through a chain, and the height is flexibly adjusted according to the road conditions, thereby improving the snow removal efficiency; by controlling the extension and contraction of the deflection hydraulic cylinder 4, the horizontal deflection of the snow shovel can be achieved, thereby adapting to the snow removal requirements of different widths; the shovel body 7, as the main component of snow removal, can directly remove the accumulated snow, and the design of the detachable shovel blade 10 enables the shovel blade to be easily replaced when worn or damaged, thereby extending the service life of the snow shovel; the heating mechanism is arranged on the shovel body 7, which can heat the shovel body during snow removal to prevent the accumulated snow from freezing on the shovel body, thereby improving the snow removal efficiency.

[0021] In a further preferred embodiment of the utility model, the heating mechanism includes: a heat-conducting shell 11 fixed on the shovel body 7; a plurality of heating tubes 12 arranged in the heat-conducting shell 11; and a thermostat 13 for temperature control arranged on the shovel body 7, wherein the thermostat 13 is adapted to the heating tubes 12.

[0022] In this embodiment, the heat-conducting shell 11 is fixed on the shovel body 7 as the external structure of the heating mechanism. Its main function is to wrap and protect the internal heating tube 12, and at the same time, as a medium for heat transfer, the heat generated by the heating tube is evenly and efficiently transferred to the shovel body 7, which can melt the snow and prevent the snow from sticking to it and affecting normal snow removal.

[0023] In a further preferred embodiment of the utility model, the shovel body 7 is symmetrically provided with a pulley assembly 8 for guiding, and the pulley assembly 8 includes a fixed frame 14, an axle rod 15, an assembly frame 6 and a pulley 16, the fixed frame 14 is fixedly mounted on the shovel body 7, the axle rod 15 is rotatably mounted on the fixed frame 14, the assembly frame 6 is fixedly mounted on the bottom end of the axle rod 15, and the pulley 16 is rotatably mounted on the assembly frame 6.

[0024] In this embodiment, a pulley assembly 8 for guiding is symmetrically arranged on the shovel body 7. The pulley assembly 8 is designed to enable the shovel body to slide along the ground more steadily and smoothly during the snow removal process, reduce the friction with the ground, thereby improving the snow removal efficiency and reducing energy consumption. At the same time, the symmetrically arranged pulley assembly 8 ensures the stability of the shovel body during movement and prevents deviation or shaking.

[0025] In a further preferred embodiment of the utility model, a hydraulic control box 9 is arranged in the lower connecting frame 3 , and the hydraulic control box 9 is adapted to the deflection hydraulic cylinder 4 and the lifting cylinder 17 .

[0026] In this embodiment, the hydraulic control box 9 is the heart of the entire hydraulic system and is responsible for controlling and managing the flow of hydraulic oil, thereby achieving precise control of hydraulic cylinders (such as the deflection hydraulic cylinder 4 and the lifting cylinder 17).

[0027] In a further preferred embodiment of the utility model, the blade 10 is provided with bolts for limiting position, and the bolts are threadedly connected to the shovel body 7 .

[0028] In this embodiment, bolts for limiting are provided on the shovel blade 10. These bolts are usually fixed at specific positions of the shovel blade for connecting and fixing with the shovel body. The provision of the bolts makes the connection between the shovel blade and the shovel body more firm and reliable, and avoids the shovel blade from falling off or loosening during snow removal operations.

[0029] To sum up, the multi-link snow shovel with adjustable snow removal angle provided by the technical solution realizes the lifting, deflection and angle adjustment functions of the snow shovel through its unique design and the coordinated work of various components, thereby improving the snow removal efficiency, reducing damage to the road surface, and expanding the application range of the snow shovel, enabling it to cope with the snow removal needs of multiple scenarios.
