Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, and specifically relates to a snowplow. Background Technology

[0002] Existing snow removal methods mainly include 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, suitable only for small areas. While chemical solvent snow removal is simple and convenient, the de-icing agents can chemically corrode the road surface, shortening its lifespan, and also cause serious environmental pollution. Mechanical snow removal is currently the most effective method, offering fast snow removal speed, high efficiency, low cost, and no environmental pollution. Therefore, various fast and economical lightweight snowplows have emerged and rapidly gained widespread application. In areas with heavy snow accumulation, small snowplows are primarily used for clearing snow, making them a widely chosen winter snow removal machine in many places such as government offices, schools, parking lots, squares, and non-motorized vehicle lanes.

[0003] Existing snowplows generally consist of an engine, transmission mechanism, snow sweeping mechanism, snow throwing mechanism, and walking mechanism. Snow throwing is a core function of snowplows and can directly affect the working efficiency of the entire snowplow. Therefore, improving snow throwing efficiency is particularly important. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a snow sweeper to improve the problem of low snow-throwing efficiency of existing snow sweepers, which affects the overall working efficiency of the snow sweeper.

[0005] To achieve the above and other related objectives, this utility model proposes a snowplow, comprising:

[0006] A housing, wherein at least the front end of the housing is provided with a snow inlet;

[0007] A cutting tool assembly, at least partially housed within the housing, is rotatably disposed relative to the housing;

[0008] The housing includes an inner surface adjacent to the tool assembly, the outer diameter of the tool assembly is provided with a predetermined gap from the inner surface, and the inner surface is provided with grooves.

[0009] In one embodiment of the present invention, along the radial direction of the tool assembly, the predetermined gap L2 between the outer diameter of the tool assembly and the inner surface satisfies: 2mm≤L2≤6mm.

[0010] In one embodiment of the present invention, the grooves are symmetrically arranged on both sides of the snow inlet.

[0011] In one embodiment of the present invention, the groove extends from a position near the side of the housing to the snow inlet and communicates with the snow inlet.

[0012] In one embodiment of this utility model, the snow inlet has a conical structure, and its angle α satisfies: 0°≤α1≤160°.

[0013] In one embodiment of the present invention, the housing further includes a snow shield, which is arranged opposite to the snow inlet and covers at least a portion of the snow inlet.

[0014] In one embodiment of the present invention, the cutting tool assembly includes a hob shaft and a snow-throwing paddle fixedly mounted on the hob shaft. The snow-throwing paddle is disposed corresponding to the snow inlet, and the width of the snow-throwing paddle is less than the maximum width of the snow inlet.

[0015] In one embodiment of the present invention, the cutting tool assembly further includes a snow winch, the snow winch including a main body portion and a first blade and a second blade extending circumferentially along the main body portion, the total axial projection angle of the first blade and the second blade being less than 360°.

[0016] In one embodiment of this utility model, the snowplow includes a main body and extension plates located on both sides of the main body. The extension plates are fixedly connected to the snow cutter, and the two extension plates are arranged at an included angle α2, wherein 0°≤α2≤180°.

[0017] In one embodiment of the present invention, along the radial direction of the tool assembly, the distance L1 between the outer diameter of the tool assembly and the bottom of the groove satisfies L1 > 10 mm.

[0018] This utility model proposes a snow sweeper, which has the following beneficial effects:

[0019] This invention effectively reduces snow throwing resistance by creating grooves on the inner surface of the shell, which are connected to the snow inlet. This allows the grooves to effectively guide snow or debris such as stones into the snow throwing channel, reducing snow accumulation on the inner wall of the cavity and thus improving the overall performance of the equipment.

[0020] This invention effectively avoids snow blockage by designing the width of the snow-throwing paddle to be smaller than the maximum width of the snow inlet, ensuring smooth snow entry into the equipment and improving snow-throwing efficiency; it also expands the snow entry area by rationally designing the shape and angle of the snow inlet, thus improving snow entry efficiency; and it further improves snow-throwing efficiency by smoothing the inner wall of the shell and the surface of the snow inlet, reducing snow flow resistance.

[0021] This invention achieves efficient snow breaking and reduces energy consumption by using a one-piece molded structure for the snow winch, including a main body and a first and second blade extending circumferentially, with a total axial projection angle of less than 360°. Additionally, extension plates are provided on both sides of the snow thrower, forming an included angle α2, which enhances the capture and guidance of snow, improving the concentration and distance of snow throwing.

[0022] This invention features connecting plates at both ends of the snow slush cutter along the axial direction, which are fixedly connected to the first and second blades respectively, thereby enhancing the overall rigidity and preventing deformation or breakage during high-speed rotation.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0038] Please see Figures 1 to 9As shown, snow throwing, as a core function of a snowplow, directly affects the overall working efficiency of the snowplow. Therefore, existing snowplows have low snow throwing efficiency, and in severe cases, snow can accumulate at the snow inlet, affecting the overall operation and significantly impacting the snowplow's efficiency. Therefore, this utility model proposes a snow thrower, including a housing 20 and a blade assembly 30, for achieving efficient and stable snow removal. The housing 20 has at least a snow inlet 201 at its front end for guiding external snow into the equipment for processing. The blade assembly 30 is at least partially housed within the housing 20 and is rotatably mounted relative to the housing 20, serving as the core working component of the snowplow. The blade assembly 30 includes a roller shaft 31, a snow-throwing paddle 32 fixedly mounted on the roller shaft 31, and snow-sweeping blades 33 located on both sides of the snow-throwing paddle 32. The snow-sweeping blades 33 are fixedly connected to the roller shaft 31 and the snow-throwing paddle 32, forming a unified working unit. The snowplow 32 is positioned corresponding to the snow inlet 201 to ensure that snow can smoothly enter the equipment and be effectively collected and thrown out.

[0039] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the snowplow also includes a snow-throwing channel 102 connected to the snow inlet 201. The snow-throwing channel 102 is used to smoothly discharge snow that has been broken by the snow cutter 33 and thrown by the snow-throwing paddle 32 to the outside of the equipment. To ensure that the snow can pass through smoothly, the inner wall of the snow-throwing channel 102 is designed as a smooth surface. Furthermore, the inner wall of the housing 20 is also designed as a smooth surface to ensure that the snow can be quickly broken by the snow cutter 33 and discharged to the outside of the equipment through the snow-throwing channel 102 after entering the equipment. Furthermore, the snow inlet 201, as the main channel for snow to enter the equipment, also has a smooth inner wall to ensure that the snow can smoothly enter the interior of the housing 20. The smooth inner wall can effectively reduce the retention of snow on the inner wall of the cavity and prevent equipment blockage caused by snow accumulation. Especially in cold environments, snow easily freezes on rough surfaces, while smooth surfaces prevent this. By reducing the friction of snow on the snow-throwing channel 102, the inner wall of the housing 20, and the inner wall of the snow inlet 201, the speed at which snow enters the snow-throwing area can be significantly increased, thereby improving the overall efficiency of the equipment. For example, it can be made of high-molecular polymers or metal materials with special coatings. These materials have good smoothness and wear resistance, maintaining surface smoothness during long-term use and reducing friction when snow passes through. Various surface treatment processes can also be used, such as polishing, electroplating, or spraying with low-friction coefficient coatings. These processes not only improve surface smoothness but also enhance the material's corrosion resistance and wear resistance.

[0040] Please see Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the housing 20 also includes a snow shield 103, which is arranged opposite to the snow inlet 201 and covers at least a portion of the snow inlet 201. This snow shield prevents snow from being sprayed forward during high-speed rotation, thereby improving the operational safety and stability of the equipment. Specifically, the snow shield 103 is installed at the intersection of the snow inlet 201 and the snow throwing channel 102, specifically above or to the side of the front end of the blade assembly 30, forming a physical barrier to prevent snow from splashing outwards during the high-speed rotation of the snow cutter 33 and the snow thrower 32. The snow shield 103 can be made of metal sheet or high-strength engineering plastic and has a certain curvature or tilt angle to guide the snow flow towards the snow throwing channel 102, preventing it from being sprayed directly forward. During snow removal operations, due to the high-speed rotation of the snow cutter 33 and the snow thrower 32, some snow may be thrown out in front of the equipment due to centrifugal force, obstructing the operator's view or even causing a safety accident. By installing the snow shield 103, the splashing snow can be effectively blocked, significantly improving the safety performance of the equipment. The snow shield 103 not only provides protection but also functions as a flow guide; its inclined surface helps redirect snow that might otherwise overflow into the snow-throwing channel 102, improving snow utilization and concentration, and enhancing the overall snow removal effect. Furthermore, traditional snowplows often generate large amounts of flying snow during operation, impacting the surrounding environment and increasing subsequent cleanup burdens. The introduction of the snow shield effectively reduces the disorderly scattering of snow, minimizing the impact on the surrounding environment and reducing unnecessary secondary cleaning work.

[0041] Please see Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the snow inlet 201 has a conical structure, meaning the diameter of the snow inlet 201 gradually decreases along a first direction X, where X is the direction from the bottom of the housing 20 to the top surface of the housing 20, forming a channel to guide snow into the equipment. This structural design effectively expands the contact area between the snowplow and the snow during operation, and through geometric guidance, concentrates the snow into the working area of ​​the blade assembly 30. The conical inlet can capture snow over a larger area, especially when clearing a wider area or when the snow is uneven, it can more effectively guide the snow into the equipment. Furthermore, the included angle α1 formed by the conical structure of the snow inlet 201 satisfies: 0°≤α1≤160°. Based on this, a further preferred angle range is: 30°≤α1≤60°. The selection of the angle α1 of the snow inlet 201 directly affects the snowplow's snow-collecting capacity, snow flowability, and overall equipment stability. The optimized angle design reduces snow accumulation at the entrance, improving the equipment's continuous operation capability and reliability. The optimized snow inlet angle makes the snow distribution more uniform, and together with the snow cutter and snow thrower, it improves the snow throwing distance and snow throwing quality.

[0042] Please see Figure 2 and Figure 3 As shown, in this embodiment, the width WB of the snow-throwing paddle 32 is less than the maximum width WA of the snow inlet 201. This design breaks with the traditional snowplow convention of designing the snow-throwing paddle width to be equal to or close to the snow inlet width. This design allows the snow inlet 201 to have more space for snow entry in the lateral direction, thereby improving the smoothness of snow entering the equipment. It is especially suitable for soft snow or heavy snow conditions, avoiding blockage problems caused by poor snow entry. Furthermore, although the width of the snow-throwing paddle 32 is slightly smaller than the maximum width of the snow inlet 201, by optimizing the rotation angle of the roller cutter, the orientation of the snow-throwing channel 102, and the arrangement of the snow-sweeping blade 33, it can still ensure effective capture and uniform distribution of snow without affecting snow-throwing efficiency. It can be understood that by designing the width of the snow-throwing paddle 32 to be less than the maximum width of the snow inlet 201, the technical effects of smooth snow entry, efficient snow throwing, and structural stability are achieved, solving the problems of poor snow entry and easy blockage in existing snowplows, and improving the adaptability and reliability of the equipment.

[0043] Please see Figure 3 and Figure 4As shown, in this embodiment, the structural design of the blade assembly 30 is optimized, with particular emphasis on the rotation sweeping angle range of the snow winch 33 to improve the equipment's working efficiency and snow removal capacity. The snow winch 33 is fixedly connected to the roller shaft 31 and the snow-throwing paddle 32, forming a single working unit. In this embodiment, the rotation sweeping angle range of the snow winch 33 is set to be adjustable from 90° to 180°, for example, by controlling the drive motor. It is understood that by setting the rotation sweeping angle of the snow winch 33 within a reasonable range, the snow collection efficiency can be significantly improved. A smaller angle allows the snow winch to quickly break and agitate the snow in a shorter time, ensuring that the snow can quickly enter the working range of the snow-throwing paddle 32. A larger angle increases the coverage area of ​​the snow winch, ensuring that the snow can be more evenly distributed throughout the working area, avoiding local snow accumulation or omissions; and different working environments have different requirements for snowplows. For example, in environments with abundant loose snow, a smaller sweeping angle can provide a higher cutting frequency, thus breaking up the snow more effectively; while in environments with hard snow or a lot of ice, a larger sweeping angle helps to expand the breaking range, ensuring that the snow can be completely removed. Therefore, a sweeping angle range of 90° to 180° allows the equipment to adapt to various working conditions, improving its versatility and practicality; and a reasonable sweeping angle not only improves the equipment's working efficiency but also reduces unnecessary energy consumption and mechanical wear. An excessively large sweeping angle may lead to overloading the equipment and increasing energy consumption; while an excessively small angle may reduce working efficiency, resulting in snow not being processed in a timely manner. By precisely controlling the sweeping angle of the snow winch, the service life of the equipment can be extended while ensuring working efficiency and reducing maintenance costs. In this embodiment, by optimizing the sweeping angle of the snow winch 33, the problems of low snow collection efficiency and poor equipment adaptability in existing snow removal equipment are solved, significantly improving the overall performance and reliability of the equipment, and has broad application prospects.

[0044] Please see Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the housing 20 also includes an inner surface 202 adjacent to the cutter assembly 30. A predetermined gap is provided between the outer diameter of the cutter assembly 30 and the inner surface 202, that is, a predetermined gap is provided between the outer contour of the rotation path of the cutter assembly 30 and the inner surface 202. For example, along the radial direction of the cutter assembly 30, the distance L2 between the outer diameter of the cutter assembly 30 and the inner wall of the housing 20 satisfies: 2mm≤L2≤6mm. A reasonable L2 value ensures that the snow shovel 33 maintains an appropriate distance from the inner wall of the housing 20 during rotation, avoiding mechanical interference caused by too small a gap and preventing snow leakage caused by too large a gap. This balanced design improves snow removal efficiency and also improves the stability and reliability of the equipment.

[0045] Please see Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, a groove 101 is provided on the inner surface 202 of the housing 20. Specifically, the height H1 of the groove 101 from the bottom of the housing 20 is less than or equal to the height H2 between the bottom of the housing 20 and the highest point of the snow winch 33. In this embodiment, grooves 101 are symmetrically provided on both sides of the snow inlet 201. Furthermore, the grooves 101 extend from the side 203 near the housing 20 to the snow inlet 201 and communicate with it. The grooves 101 can effectively reduce the snow throwing resistance, allowing the grooves 101 to effectively guide snow or debris such as stones into the snow throwing channel, reducing the accumulation of snow on the inner wall of the cavity, thereby improving the overall performance of the equipment. It is understood that the number of grooves 101 located on one side of the snow inlet 201 can be designed as one, two, or more, which helps snow to enter the snow throwing channel 102 smoothly and reduces the retention of snow on the inner wall of the cavity.

[0046] Please see Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the radial distance design between the cutter assembly 30 and the groove 101 is further optimized to ensure efficient operation and structural stability of the equipment. Along the radial direction of the cutter assembly 30, the distance L1 between the outer diameter of the cutter assembly 30 and the bottom of the groove 101 satisfies: L1 > 10mm. This larger radial distance ensures that the snow winch 33 has sufficient working space, preventing the groove 101 from malfunctioning due to insufficient clearance, which could cause snow, stones, or other debris to get stuck between the groove 101 and the cutter assembly 30. This ensures that the groove 101 effectively guides snow or stones into the snow-throwing channel, reducing snow accumulation on the inner wall of the cavity.

[0047] Please see Figure 7 and Figure 8As shown, in this embodiment, the snow winch 33 is a one-piece molded structure, including a main body 331 and a first blade 332 and a second blade 333 extending circumferentially along the main body. This structural design not only improves the overall strength and durability of the snow winch but also enhances the working efficiency and stability of the equipment through reasonable control of its axial projection angle. The snow winch 33 is manufactured using a one-piece molding process. The main body 331 serves as the central support structure of the entire snow winch 33, connecting the roller shaft 31 and bearing the torque and impact force generated during rotation. The first blade 332 and the second blade 333 extend outward from the main body 331 to form functional components for cutting and breaking snow. The two blades are distributed at a certain angle on the main body 331 to ensure uniform breaking of snow during rotation. It is understood that the one-piece structure avoids the risk of fracture caused by stress concentration in traditional welded or spliced ​​structures, simplifies the assembly process, and reduces production costs and maintenance difficulty.

[0048] Please see Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, the total axial projection angle γ of the first blade 332 and the second blade 333 is less than 360°, i.e., γ1 + γ2 < 360°. This design breaks away from the traditional snow cutter's full-circumference coverage structure. When the snow cutter 33 rotates at high speed, if the blade coverage angle is 360°, it will generate significant wind resistance due to air agitation, affecting equipment efficiency. Limiting the total axial projection angle to less than 360° can effectively reduce air resistance and unnecessary energy loss. In this embodiment, by rationally allocating the space between the first blade 332 and the second blade 333, the snow can be guided towards the snowplow 32 while ensuring breaking efficiency, thus improving overall snow removal efficiency. At the same time, the discontinuous blade structure also helps prevent large pieces of ice and snow from getting stuck. Furthermore, because the blade coverage angle is small, the overall weight is reduced, achieving lightweight design without sacrificing strength. This structure is also more conducive to achieving dynamic balance, reducing vibration and noise generated during equipment operation.

[0049] Please see Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the structural design of the snow winch 33 is further optimized. Connecting plates 334 are provided on both sides along its axial direction, and these connecting plates 334 are fixedly connected to the first blade 332 and the second blade 333, respectively. This structural design effectively enhances the overall rigidity and deformation resistance of the snow winch, making it particularly suitable for snow removal operations under high-speed rotation conditions. The connecting plates 334 are plate-shaped structures made of metal or high-strength composite materials with a certain thickness, and are respectively installed at both ends of the snow winch 33 along its axial direction. In this embodiment, the connecting plates 334 are located between the outer ends of the first blade 332 and the second blade 333, forming a closed or semi-closed frame structure. The connecting plates 334 can be firmly connected to the first blade 332 and the second blade 333 through welding, bolting, riveting, or integral molding, ensuring that they will not loosen or fall off during high-speed rotation. The connecting plates 334 not only provide support and reinforcement but also guide the snow flow to a certain extent, improving the overall working performance of the equipment.

[0050] Understandably, since the snow auger blade 33 needs to withstand significant impact and centrifugal force during snow removal, traditional unconnected structures are prone to problems such as blade bending and main body deformation. This embodiment, by providing connecting plates 334 on both axial sides, significantly improves the overall rigidity of the snow auger blade, preventing structural deformation caused by uneven stress. The introduction of connecting plates 334 in this embodiment gives the snow auger blade 33 better dynamic balance characteristics during rotation, reducing vibration and noise caused by structural asymmetry or uneven local mass distribution, thus improving the stability and comfort of equipment operation. Furthermore, because snow auger blades are prone to fatigue damage due to stress concentration under prolonged high-speed operation, the presence of connecting plates 334 in this embodiment effectively disperses the stress points, avoiding excessive local stress, thereby extending the service life of the snow auger blade and reducing maintenance frequency.

[0051] Please see Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the snowplow 32 includes a main body 321 and extension plates 322 located on both sides of the main body. The extension plates 322 are fixedly connected to the snow cutter blades 33. The main body 321 serves as the main structure of the snowplow 32, used to be mounted on the roller shaft 31 and to withstand the centrifugal force and impact force generated during rotation. The extension plates 322 are respectively disposed on both sides of the main body 321, extending outward to form functional surfaces with a certain arc or tilt angle, used to capture and accelerate snow accumulation, causing it to be thrown out in a specific direction. The extension plates 322 and the snow cutter blades 33 are fixedly connected by welding, screwing, or integral molding, so that the entire blade assembly 30 forms a stable rotating whole. Specifically, the two extension plates 322 located on both sides of the main body are respectively connected to the snow cutter blades 33 on both sides of the snowplow 32. Specifically, the snowplow includes two snowplows 32, which are used for two first blades 332 and two second blades 333, respectively. In this embodiment, the two extension plates 322 are arranged at an angle α2, wherein: 0°≤α2≤180°. Preferably, the angle α2 is set to: 0°≤α2≤120°. The appropriately opened extension plate structure can effectively expand the snow entry area, ensure that the snow quickly enters the working range of the snowplow, and at the same time make the snow throwing direction more concentrated. By reasonably designing the angle α2 between the extension plates, the snow throwing direction can be flexibly controlled to adapt to various working environments and enable it to be accurately thrown to the snow entry 201.

[0052] In this embodiment, the snow sweeper also includes a frame, which serves as the basic support structure for the entire equipment. Fixing plates 11 are provided on its opposite sides to enhance the overall structural strength and provide an installation base for other components. The body 20 is installed on the front side of the frame 10 and is fixedly connected to the fixing plates 11.

[0053] This utility model overcomes the shortcomings of traditional snow removal equipment, such as poor snow entry, low snow throwing efficiency, insufficient structural strength, high energy consumption, and easy clogging, through a series of structural optimizations and technical improvements. It provides a new type of snow removal machine that is efficient, durable, safe, and highly adaptable, with significant technological progress and practical value, and has broad market application prospects.
