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 sweeping 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 suffer from several structural shortcomings. For example, the overall structure is poorly arranged; the control board's location lacks effective heat dissipation, making it susceptible to overheating and damage. Insufficient electrostatic protection also poses a risk of electric shock. The control board is deeply embedded inside the machine, requiring the disassembly of multiple components for access, making operation cumbersome. Furthermore, the airflow design is inadequate, resulting in chaotic airflow paths, low heat dissipation efficiency, and poor waterproofing, allowing rainwater to easily seep in through the air inlet. These problems collectively limit the reliability, safety, and user experience of snowplows, necessitating structural optimization to achieve a breakthrough. 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 that optimizes the layout of various structures to solve the various deficiencies in the structure of existing snow sweepers. For example, the control board is generally directly installed inside the casing, lacking an effective heat dissipation design, which makes it prone to damage due to overheating. At the same time, there is insufficient electrostatic protection, which poses a risk of electric shock. The control board is deeply buried inside the casing, requiring the disassembly of multiple parts to access it, which is cumbersome. In addition, the air duct design is imperfect, the airflow path is chaotic, the heat dissipation efficiency is low, and the waterproof performance is poor, allowing rainwater to easily seep in through the air inlet.

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

[0006] frame;

[0007] A housing is fixedly connected to the frame. The housing includes a front housing located on the front side of the frame. At least the front end of the front housing is provided with a snow inlet.

[0008] A tool assembly, at least partially housed within the front housing, is rotatably disposed relative to the frame;

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.

[0019] In one embodiment of the present invention, a metal guide plate and a foot are also included. The metal guide plate is disposed at both ends of the inner side of the front housing, and the metal guide plate is provided with at least two parallel slots that extend along the height direction. The foot is installed in the slots by fastening bolts.

[0020] In one embodiment of the present invention, a movable wheel assembly is further included. The movable wheel assembly includes a wheel axle and movable wheels located on both sides of the frame. The two ends of the wheel axle are respectively connected to the fixed plate, and the distance L between the hob axis of the cutter assembly and the wheel axle axis satisfies the relationship: 170mm≤L≤400mm.

[0022] In one embodiment of the present invention, the battery assembly includes a battery pack compartment and at least one battery pack installed in the battery pack compartment, wherein the angle α between the insertion / removal direction of the battery pack in the battery pack compartment and the ground satisfies: 0°≤α≤100°.

[0023] In one embodiment of this utility model, when the battery pack compartment has a battery pack cavity, the voltage of the battery pack is 60V or 80V;

[0024] When the battery pack compartment has two battery pack cavities, the total voltage of the two battery packs is 60V or 80V, or the voltage of a single battery pack is one of 24V, 40V, and 48V.

[0074] The following specific examples illustrate the implementation of this utility model. 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.

[0075] 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.

[0076] 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.

[0077] Please see Figures 1 to 37 As shown, this utility model proposes a snow sweeper that optimizes the layout of various structures to address various shortcomings of existing snow sweeper structures. For example, the existing control board has an unreasonable position design, lacking effective heat dissipation and making it prone to overheating damage; it also lacks sufficient electrostatic protection, posing a risk of electric shock; the control board is deeply embedded in the casing, requiring the disassembly of multiple components for access, making operation cumbersome; and the airflow design is imperfect, resulting in chaotic airflow paths, low heat dissipation efficiency, and poor waterproofing, allowing rainwater to easily seep in through the air inlet. In this embodiment, the snow sweeper includes the frame 10, casing, control module 40, blade assembly 50, motor 60, battery assembly 80, and moving wheel assembly 90. The housing is mounted on the frame 10. The tool assembly 40 is at least partially housed within the housing and is rotatably mounted relative to the frame. Specifically, the housing includes a front housing 20, which is fixedly connected to the frame 10 and located at the front of the frame 10. The tool assembly is at least partially housed within the front housing 20 and is rotatably connected relative to the front housing 20. At least the front end of the front housing 20 is provided with a snow inlet 260. The battery assembly 80 is installed inside the housing and located on the side of the front housing 20 away from the tool assembly 50. The motor 60 is mounted on the frame 10 and located inside the housing. The motor 60 is connected to the tool assembly 50 via a transmission connection, driving the tool assembly 50 to rotate. The control module 40 is located at the bottom of the housing and is connected to both the motor 60 and the battery assembly 80. The caster assembly 90 is mounted on the rear side of the frame 10.

[0078] Please see Figure 1 , Figure 2 , Figure 3 , Figure 11 and Figure 15As shown, this embodiment also includes an electrostatic shielding bracket 30, through which the control module 40 is connected to the rack 10. In this embodiment, the electrostatic shielding bracket 30 is made of a conductive material, such as a metal electrostatic shielding bracket. The rack 10 is designed with a grounding end, and the rack 10 is configured to conduct static electricity on the electrostatic shielding bracket 30 to the grounding end and release it. By placing the control module 40 on the electrostatic shielding bracket 30, this embodiment can effectively isolate electrostatic interference generated by friction from the front housing 20, the tool assembly 50, and other parts, preventing static electricity from directly acting on sensitive electronic components. Furthermore, because the electrostatic shielding bracket 30 itself has good conductivity and is reliably connected to the rack 10, static electricity entering the housing can be quickly guided to the grounding end for release, thereby avoiding static electricity accumulation and discharge phenomena. In this embodiment, the control module 40 is protected by both physical and electromagnetic means, which greatly reduces the damage rate of electronic components caused by electrostatic discharge, improves the stability and service life of the whole machine, and the electrostatic shielding bracket 30 not only protects the control circuit, but also reduces the risk of static electricity being released through the human body, thus improving the safety of the operator.

[0079] Please see Figure 1 , Figure 2 , Figure 3 , Figures 7 to 15As shown, in this embodiment, the frame 10 serves as the basic support structure for the entire device. The frame 10 includes a fixing plate, which is installed on the side of the front housing 20. The electrostatic shielding bracket 30 is in contact with the fixing plate. Specifically, the fixing plate includes a first fixing plate 111 and a second fixing plate 112. The first fixing plate 111 and the second fixing plate 112 are located on two opposite sides of the front housing 20, used to enhance the overall structural strength and provide an installation base for other components. The front housing 20 is installed between the first fixing plate 111 and the second fixing plate 112, used to accommodate snow-sweeping components such as the blade assembly 50. The electrostatic shielding bracket 30 is installed at the bottom of the housing and is fixedly connected to the first fixing plate 111, the second fixing plate 112, and the front housing 20, respectively. The control module 40 is installed on the electrostatic shielding bracket 30 and is used to control the electrical system of the entire machine. Further, the control module 40 is installed on the side of the electrostatic shielding bracket 30 away from the housing 20, so that the electrostatic shielding bracket 30 separates the control module 40 from the housing 20, preventing the static electricity generated by the housing 20 from damaging the control module 40. In this embodiment, the first fixing plate 111 and the second fixing plate 112 can be made of conductive materials, such as metal fixing plates. The electrostatic shielding bracket 30 is connected to the metal fixing plate, allowing static electricity to be conducted through the metal fixing plate to the near-ground end of the frame 10 and then released. Furthermore, the two end faces of the electrostatic shielding bracket 30 are respectively in contact with the first fixing plate 111 and the second fixing plate 112. This surface contact increases the electrostatic conduction area, unlike traditional point or line contact. By increasing the contact area, it significantly improves the conductivity and stability of the electrostatic conduction path, thereby effectively improving the electromagnetic compatibility and anti-static interference capability of the entire machine. The electrostatic shielding bracket 30 is a highly conductive metal component with flat end face structures at both ends, which are tightly fitted with the corresponding mounting surfaces of the first fixing plate 111 and the second fixing plate 112 to ensure good conductive continuity between the contact surfaces.

[0080] Please see Figure 4 , Figure 5 , Figure 16 , Figure 17 , Figure 18 , Figure 21 and Figure 22As shown, in this embodiment, the electrostatic shielding bracket 30 is located on the rear side of the front housing 20, i.e., the side opposite to the blade assembly 50. The electrostatic shielding bracket 30 includes a first end 311 and a second end 312 disposed opposite to each other, and a top surface 314 located between the first end 311 and the second end 312. The first end 311 is fixedly connected to the first fixing plate 111, and the second end 312 is fixedly connected to the second fixing plate 112. The control module 40 is mounted on the top surface 314. In this embodiment, the electrostatic shielding bracket 30 also includes a front side surface 313 located between the first end 311 and the second end 312. The front side surface 313 is adjacent to the top surface 314 and is fixedly connected to the front housing 20, thereby achieving stable assembly between the electrostatic shielding bracket 30 and the main structure of the snow sweeper and ensuring the continuity of the electrostatic path.

[0081] Understandably, surface contact significantly increases the effective area for electrostatic conduction, thereby reducing the resistance value of the contact interface and improving the efficiency of electrostatic discharge. Due to the large contact area and uniform force distribution, the connection structure is less prone to poor contact due to vibration or temperature changes during equipment operation, thus improving connection stability. The good conductivity between the electrostatic shielding bracket 30 and the fixed plate helps to form a complete electrostatic shielding electrostatic discharge path, preventing electrostatic accumulation from interfering with or damaging the internal circuits, and effectively enhancing the shielding effect.

[0082] Please see Figure 2 , Figure 3 , Figure 6 , Figures 4 to 18 As shown, in this embodiment, the cutter assembly 50 is used to crush and throw snow. The cutter assembly 50 includes a roller shaft 51, a snow-throwing paddle 52, and a snow-spinning blade 53. The roller shaft 51 is the core transmission component of the cutter assembly, and its two ends are rotatably connected to the first fixed plate 111 and the second fixed plate 112, respectively. The snow-throwing paddle 52 is fixedly installed on the roller shaft 51 and is used to throw out the snow that enters the equipment. The snow-spinning blade 53 is arranged on both sides of the snow-throwing paddle 52 and is used to crush and agitate the snow to improve the snow intake efficiency.

[0083] Please see Figure 1 , Figure 20 , Figure 22 , Figure 23 and Figure 24 As shown, in this embodiment, the motor 60 is mounted on the frame 10 and is connected to the cutter assembly 50 via a transmission connection, specifically to the roller shaft 51, to drive the roller shaft 51 to rotate, thereby causing the snow-throwing paddle 52 and the snow-sweeping blade 53 to rotate synchronously. Through this structural design, the cutter assembly 50 can efficiently complete the tasks of collecting, crushing, and throwing snow, ensuring the continuity and efficiency of snow removal operations.

[0084] Please refer to Figure 20 , Figure 22 , Figure 23 and Figure 24 As shown, in this embodiment, the motor 60 is fixedly mounted on a mounting plate. The frame 10 is configured to conduct static electricity from the motor 60 to a near-ground end for release, thus preventing static electricity accumulation from damaging the motor 60. Specifically, the motor 60 is mounted on one of the mounting plates, for example, on a second mounting plate 112. The second mounting plate 112 allows the static electricity from the motor 60 to be conducted to a near-ground end of the frame 10 for release. Further, in this embodiment, the motor 60 includes a motor bracket 61, which is in surface contact with and fixedly connected to the second mounting plate 112. Surface contact significantly increases the effective area for static electricity conduction, thereby reducing the resistance value of the contact interface and improving the static electricity discharge efficiency. Due to the large contact area, the motor 60 is less prone to poor contact due to vibration during equipment operation, thus improving connection stability, ensuring good conductivity between the motor and the mounting plate, contributing to the stability of the static electricity conduction path, and preventing static electricity accumulation from interfering with or damaging the motor.

[0085] Please see Figure 2 , Figure 3 , Figures 6 to 14 As shown, in this embodiment, the cutting tool assembly 50 will experience strong friction with the snow during high-speed rotation, easily generating a large amount of static electricity. Therefore, this invention proposes a static electricity release path design. Specifically, both ends of the hobbing shaft 51 are connected to fixed plates, namely the first fixed plate 111 and the second fixed plate 112, to achieve electrical conduction. Furthermore, both end faces of the static shielding bracket 30 are contacted and connected to the first fixed plate 111 and the second fixed plate 112, respectively, to achieve electrical conduction. This creates a closed conductive path between the static shielding bracket 30, the first fixed plate 111, the second fixed plate 112, and the hobbing shaft 51, thus constituting a static electricity release path. This path allows static electricity to be conducted to the near-ground end and released. Understandably, this electrostatic discharge path design prevents the static electricity generated by the tool assembly 50 during operation from directly affecting the control module 40. Instead, it effectively conducts the static electricity to the near-ground end of the frame 10 and releases it, effectively preventing damage to electronic components due to electrostatic breakdown. This electrostatic discharge path can be implemented based on existing metal connections between structures, eliminating the need for additional complex conductive components. It features a simple structure, low manufacturing cost, ease of implementation, and convenient application. This invention, by constructing an electrostatic discharge path composed of an electrostatic shielding bracket 30, a first fixing plate 111, a second fixing plate 112, and a hobbing shaft 51, can dissipate static electricity generated by friction and snow accumulation during the high-speed rotation of the snow hobbing blade. This effectively solves the problems of significant static electricity hazards and susceptibility to damage to electronic control systems in existing technologies, demonstrating significant technological advancement and practical application value.

[0086] Please see Figure 2 , Figure 3 , Figures 6 to 14 As shown, in this embodiment, a bearing assembly 311 is sleeved at the end of the hob shaft 51. The bearing assembly 311 ensures the smooth rotation of the cutter assembly 50. The fixing plate is at least partially in contact with the bearing assembly 311, and further, the fixing plate and the bearing assembly 511 are in surface contact. In this embodiment, the bearing assembly 511 includes a bearing housing and a bearing. The bearing is installed in the bearing housing and sleeved on the hob shaft 51. Taking the first fixing plate 111 as an example: The first fixing plate 111 is located on the outer side 211 of the front housing 20, and a first protrusion 1111 is formed on a part of the first fixing plate 111 facing away from the front housing 20. That is, the side of the first fixing plate 111 facing away from the front housing 20 is recessed to form an accommodating space. The recessed part of the first fixing plate 111 appears as the first protrusion 1111 on the side facing away from the front housing 20. The bearing assembly 311 is installed in the accommodating space, so that the inner surface of the first protrusion 1111 contacts and connects with the bearing assembly 311. The first protrusion 1111 restricts the position of the bearing assembly 311 and can also increase the contact area between it and the fixing plate, thereby increasing the electrostatic conduction area and ensuring the electrical conduction between the tool assembly 50 and the fixing plate. This significantly improves the conduction efficiency and stability of the electrostatic conduction path, thereby effectively improving the electromagnetic compatibility and anti-static interference capability of the whole machine.

[0087] Please see Figure 2 , Figure 3 , Figure 4 , Figures 6 to 14As shown, in this embodiment, the movable wheel assembly 90 includes an axle 91 and movable wheels 92 located on both sides of the frame 10. The two ends of the axle 91 are connected to fixed plates, namely the first fixed plate 111 and the second fixed plate 112. The movable wheels 92 are connected to the axle 91 to support the entire machine and enable the snow sweeper to move forward or backward. The axle 91 is made of metal and has good electrical conductivity, providing a physical path for electrostatic discharge while fulfilling the mechanical transmission function. Furthermore, the electrostatic shielding bracket 30 is electrically connected to the first fixed plate 111 and the second fixed plate 112, and the axle 91 also maintains good conductive contact, thus forming an electrostatic discharge path among the electrostatic shielding bracket 30, the first fixed plate 111, the second fixed plate 112, and the axle 91. This electrostatic discharge path can quickly guide static electricity generated by ground friction or other reasons to the ground during the snow sweeper's movement, preventing the accumulation of static electricity on the equipment surface and thus preventing static electricity from interfering with or damaging the control module 40. Simultaneously, this electrostatic discharge path also reduces the risk of electrostatic shock to operators when touching the equipment, improving the safety and reliability of the equipment. In this embodiment, a connector 113 is provided at the bottom of the fixed plate, and the wheel axle 91 is fixedly connected to the connector 113. The connector 113 is at least partially configured as an arc-shaped structure, which is adapted to the axle surface of the wheel axle 91. This arc-shaped structure forms a stable connection with the wheel axle 91 and increases the electrostatic conduction area, ensuring electrical conduction between the wheel axle 91 and the fixed plate. This significantly improves the conductivity and stability of the electrostatic conduction path, thereby effectively improving the electromagnetic compatibility and anti-static interference capability of the entire machine. Of course, surface contact can also be achieved by designing bushings or other structures to increase the electrostatic conduction area.

[0088] Please see Figure 6 and Figure 22 As shown, in this embodiment, the moving wheel assembly 90 is located at the rear of the frame 10, and the front housing 20 is located at the front of the frame 10. That is, the moving wheel assembly 90 and the front housing 20 are arranged at both ends of the fixed plate along the first direction X, and the distance L between the axis of the wheel axle 91 and the axis of the cutter shaft 51 satisfies 170mm≤L≤400mm. If L is too small, it means that the wheel is too close to the cutter, resulting in insufficient front and rear space of the whole machine, a crowded structure, limited space for center of gravity adjustment, and affecting stability. If L is too large, the machine becomes longer, which can easily lead to inflexible steering, especially in narrow areas. Furthermore, the center of gravity of the snow sweeper is located between the wheel axle 91 of the moving wheel assembly 90 and the cutter shaft 51 of the cutter assembly 50, which helps to ensure that the equipment remains stable during operation, avoids forward or backward tilting due to center of gravity shift, and improves operational safety and sweeping efficiency.

[0089] Please see Figure 2, Figure 3 , Figures 6 to 14 As shown, in this embodiment, the snowplow further includes a lower push rod 70, which is connected to the electrostatic shielding bracket 30 or a fixed plate to form an electrostatic discharge path. For example, the lower push rod 70 is made of metal and has good conductivity. It is firmly connected to the electrostatic shielding bracket 30, the first fixed plate 111, and the second fixed plate 112 by bolts, welding, or other means to ensure structural stability and conductive continuity, thus forming an electrostatic discharge path between the electrostatic shielding bracket 30 and the lower push rod 70. This electrostatic discharge path can quickly conduct any static electricity that may be carried by the operator or accumulated on the outside of the equipment into the electrostatic shielding bracket 30 when the operator touches the lower push rod 70, and guide it to the ground through the whole machine grounding system, preventing static electricity from being released through the human body during operation and causing electric shock. At the same time, this electrostatic discharge path also helps to prevent electrostatic interference with the control module 40 and improves the operational stability of the electronic system. The electrostatic discharge path is achieved through the structural connection between the lower push rod 70 and the electrostatic shielding bracket 30, without the need for additional independent conductive components. This not only simplifies the overall wiring structure but also improves the integration and practicality of the electrostatic protection system. Since this electrostatic discharge path relies on the existing metal connections between structures, no additional complex conductive components are needed. This simplifies the assembly process, facilitates later maintenance, and improves the overall integration and practicality of the equipment. In this embodiment, the electrostatic shielding bracket 30 has grooves 315 at both ends on the side away from the front housing 20. The lower push rod 70 is located within the grooves 315, allowing the axial surfaces of the electrostatic shielding bracket 30 and the lower push rod 70 to make surface contact. This increases the electrostatic conduction area, significantly improving the conductivity and stability of the electrostatic conduction path, thereby effectively enhancing the electromagnetic compatibility and anti-static interference capability of the entire device.

[0090] Please see Figure 2 , Figure 3 , Figures 4 to 12As shown, in this embodiment, the frame 10 also includes a metal guide plate 11 and a foot 12. The metal guide plate 11 is installed on both sides of the front housing 20 and located inside the front housing 20. The metal guide plate 11 is at least partially in contact with the bearing assembly 311. Furthermore, the metal guide plate 11 and the bearing assembly 511 are in surface contact connection. Specifically, a second protrusion 1101 is formed on a portion of the metal guide plate 11 facing away from the side of the front housing 20. That is, the metal guide plate 11 is recessed inward from the front housing 20 to form a receiving space. This recessed portion appears as the second protrusion 1101 on the side of the metal guide plate 111 facing away from the front housing 20. The bearing assembly 311 is installed in this receiving space, so that the inner surface of the second protrusion 1101 contacts and connects with the bearing assembly 311. The second protrusion 1101 and the first protrusion 1111 restrict the axial position of the bearing assembly 311, and at the same time, they can increase the electrostatic conduction area, significantly improve the conduction efficiency and stability of the electrostatic conduction path, thereby effectively improving the electromagnetic compatibility and anti-static interference capability of the whole machine. In this embodiment, a foot 12 is installed on the outer side of the metal guide plate 11. This foot 12 serves as part of the bottom support structure of the snowplow, adjusting the overall ground clearance of the equipment and preventing wear or damage to the snow-rolling blade assembly during snow removal due to contact with the ground. Simultaneously, the foot 12 also acts as the near-ground end of the frame 10 for static electricity discharge; static electricity is conducted to the foot 12 via the metal guide plate 11 and then released. In this embodiment, the foot 12 is slidably connected to the metal guide plate 11 for adjustable assembly. Specifically, the metal guide plate 11 has at least two parallel slots 13 extending along the height direction to form a sliding path. The foot 12 is installed in the slots 13 by fastening bolts, allowing it to move up and down within a certain range along the height direction, and its height can be locked by adjusting the position of the bolts.

[0091] It is understandable that by fixing the feet 12 at different positions in the slots 13, users can flexibly adjust the ground clearance of the snow sweeper according to the actual usage scenario to adapt to snow layers of different thicknesses or different types of ground conditions. Through the cooperation of the feet 12 and the metal guide plate 11, a reasonable distance between the snow-rolling blade assembly and the ground can be maintained during the sweeping process, avoiding unnecessary wear and extending the service life of the equipment. That is, in this embodiment, by setting multiple slots 13 extending along the height direction on the metal guide plate 11 and installing the feet 12 in them with fastening bolts, the flexible adjustment and stable connection of the foot height are realized, which improves the snow sweeper's adaptability to complex terrain and its stability and safety during operation.

[0092] In this embodiment, one or more grounding terminals may be provided on the frame 10 to conduct static charges generated during equipment operation to the ground and release them safely. The distance between the grounding terminal and the ground is less than or equal to 200 mm, and further, less than or equal to 50 mm, thereby ensuring that static electricity can be effectively released through air breakdown or direct contact, avoiding the impact of static electricity accumulation on equipment operation. The grounding terminal may be a conductive metal block or other structural components with conductive functions, preferably made of materials with good conductivity and wear resistance, such as brass, stainless steel, or conductive composite materials. The grounding terminals may be evenly distributed along the bottom edge of the frame 10 to ensure that when static electricity accumulates in any location of the equipment, it can be effectively released through the nearest grounding terminal. In some preferred embodiments, the grounding terminals may be integrally formed with the frame 10 or detachably connected by screws, clips, etc., for easy replacement or maintenance in the future.

[0093] Please see Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figure 19 , Figure 21 , Figures 25 to 27 As shown, in this embodiment, the housing is arranged between the first fixing plate 111 and the second fixing plate 112, and is fixedly connected to the first fixing plate 111 and the second fixing plate 112. The housing also includes a lower cover 14, a lower housing 15, and an upper cover 16. The upper cover 16 covers the lower housing 15 to form a first cavity 110 between the upper cover 16 and the lower housing 15. The motor 60 and the battery assembly are housed in the first cavity 110. The lower cover 14 covers the bottom of the electrostatic shielding bracket 30 and is fixedly connected to the lower housing 15. The lower cover 14 and the electrostatic shielding bracket 30 enclose a second cavity 120, and the control module 40 is housed in the second cavity 120. Specifically, the lower cover 14 is arranged opposite to the top surface 314 of the electrostatic shielding bracket 30 and covers the lower part of the control module 40 to protect the internal control module 40. In this embodiment, the lower cover 14 is detachably connected to the frame 10 and the front housing 20, for example, by means of screws, clips, or quick-release structures for assembly and disassembly. This detachable design allows operators or maintenance personnel to quickly open the lower cover 14 when needed to inspect, replace, or maintain the control module 40, improving the maintainability and ease of use of the equipment.

[0094] Understandably, in this embodiment, the front side 313 of the electrostatic shielding bracket 30 is also fixedly connected to the front housing 20, making the control module and the front structure of the snow sweeper form an integral whole, enhancing structural rigidity and saving internal space. Furthermore, the lower cover 14 is detachably connected to both the lower housing 15 and the front housing 20. Specifically, the lower cover 14 is connected to the aforementioned components via screws, clips, or other conventional fasteners, facilitating quick disassembly when needed for inspection, replacement, or cleaning of the control module 40. This detachable structural design not only improves the maintainability and assembly efficiency of the equipment but also facilitates future upgrades or replacements of electronic components, reducing maintenance costs. In addition, while ensuring airtightness, it effectively prevents the influence of external environmental factors such as dust and moisture on the control module 40, improving the reliability and service life of the electronic control system. In this embodiment, by fixing the electrostatic shielding bracket 30 to the first fixing plate 111, the second fixing plate 112 and the front housing 20, and by using a detachable lower cover 14 to cooperate with the lower housing 15 and the front housing 20, the stability and maintenance convenience of the control module 40 are achieved, further improving the overall engineering practicality of the snow sweeper.

[0095] Please see Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figures 19 to 21 As shown, in this embodiment, the electrostatic shielding bracket 30 is a metal part with good thermal conductivity. The control module 40 is installed on the electrostatic shielding bracket 30. In addition to the electrostatic shielding function mentioned above, the electrostatic shielding bracket 30 can also serve as a heat dissipation bracket. The heat of the control module 40 can be conducted through the electrostatic shielding bracket 30 to the metal part on the frame 10 that is in direct contact with the snow, and then the snow will carry away the heat to achieve heat dissipation and cooling.

[0096] Please see Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figures 19 to 21 As shown, in this embodiment, the metal component includes at least one fixing plate, which can be either the first fixing plate or the second fixing plate described in the above embodiments. The electrostatic shielding bracket 30 is connected to the fixing plate, and the electrostatic shielding bracket 30 conducts the heat from the control module 40 to the fixing plate. Preferably, the metal component includes a first fixing plate 111 and a second fixing plate 112. The two end faces of the electrostatic shielding bracket 30 are respectively connected to the first fixing plate 111 and the second fixing plate 112. The electrostatic shielding bracket 30 conducts the heat from the control module 40 to the fixing plate, and the heat from the control module 40 is carried away by the contact between the electrostatic shielding bracket 30 and the fixing plate. Furthermore, the electrostatic shielding bracket 30 and the fixing plate are in surface contact, which increases the heat conduction area and thus improves the heat conduction efficiency and cooling efficiency.

[0097] Please see Figure 4 , Figure 5 , Figure 6 , Figures 12 to 15 As shown, in this embodiment, to improve the heat dissipation capacity of the control module 40 under high load conditions, a heat dissipation component 31 is provided on the control module 40. This heat dissipation component 31 is in contact with the electrostatic shielding bracket 30 to improve the heat dissipation effect on the control module 40. Furthermore, the control module 40 is mounted on the electrostatic shielding bracket 30 and connected to it via the heat dissipation component 31. The heat dissipation component 31 conducts heat from the control module 40 to the electrostatic shielding bracket 30, and then to the metal components. Further still, the heat dissipation component 31 and the control module 40 are in surface contact, and the heat dissipation component 31 and the electrostatic shielding bracket 30 are thermally connected, for example, through thermally conductive adhesive. The surface connection between the heat dissipation component 31 and the control module 40 increases the heat conduction area, thereby improving the heat conduction efficiency. The thermally conductive adhesive connection between the heat dissipation component 31 and the electrostatic shielding bracket 30 further enhances the heat conduction efficiency, effectively dissipating heat from the control module 40 and achieving the heat dissipation effect on the control module 40. Of course, the heat dissipation component 31 and the electrostatic shielding bracket 30 are connected by surface contact or through thermal pads to achieve efficient heat conduction.

[0098] In this embodiment, the heat dissipation component 31 is configured as a multi-row heat sink. The multi-row heat sink is arranged at intervals along the distribution direction of the heat-generating elements in the control module 40 and connected to the electrostatic shielding bracket 30. Specifically, the heat sink is made of a metal material with good thermal conductivity (e.g., aluminum or copper) and is fixedly mounted on the surface of the control module 40, particularly concentrated in areas with high heat generation such as power devices and chips. By increasing the heat dissipation area, the efficiency of heat conduction from the circuit board to the surrounding environment is improved, thereby effectively reducing the local temperature and preventing electronic component failure or performance degradation due to overheating. When the control module 40 is working, the generated heat is sequentially conducted through the heat sink to the electrostatic shielding bracket 30, and then further conducted to the fixed plate by the metal structure of the electrostatic shielding bracket 30 itself, forming a good passive heat dissipation path.

[0099] Please see Figure 2 , Figure 3 , Figure 6 , Figures 22 to 24 , Figure 27As shown, in this embodiment, the motor 60 is located in the first cavity and fixedly mounted on the fixed plate. The motor 60 is connected to the tool assembly 40 via a transmission connection, driving the tool assembly 40 to work. When the metal part includes a first fixed plate 111 and a second fixed plate 112, the motor 60 can be mounted on either fixed plate. Taking the motor 60 fixedly mounted on the second fixed plate 112 as an example, the heat from the motor 60 can be carried away by snow through the heat conduction of the second fixed plate 112, achieving a cooling effect on the motor 60. Furthermore, a fan is also provided on the main shaft of the motor 60, which can further improve the cooling effect of the motor 60.

[0100] Please see Figure 25 As shown, in this embodiment, the transmission assembly is installed on the side of the second fixing plate 112 away from the motor 60. The transmission assembly is connected to the motor 60 and the tool assembly 50 respectively. The motor 60 drives the tool assembly 50 to work through the transmission assembly. A protective cover 620 is provided on the outside of the transmission assembly. The protective cover 620 is fixedly connected to the second fixing plate 112 and plays the role of protecting the transmission assembly.

[0101] Please see Figure 4 , Figure 5 , Figure 19 and Figure 27 As shown, in this embodiment, the snow sweeper also includes a motor cover 610 for enhancing the heat dissipation of the motor 60. The motor cover 610 is connected to the second fixing plate 112 and covers the outside of the motor 60 and the fan. Specifically, the motor cover 610 is generally shell-shaped or has a guide shield structure, with a certain gap maintained between its inner wall and the outer shell of the motor 60 to allow cooling airflow to flow around it. At the same time, one end of the motor cover 610 is sealed or semi-sealed to the second fixing plate 112, so that it and the second fixing plate 112 enclose a relatively independent air duct structure, thereby guiding and concentrating the cooling airflow over the surface of the motor 60 and improving the heat dissipation efficiency.

[0102] Please see Figure 5 , Figures 19 to 22 , Figures 26 to 30As shown, in this embodiment, the housing is provided with an air inlet and an air outlet 101. For example, the air inlet and air outlet 101 are located at the bottom of the housing and face downwards. The heat dissipation bracket 50 has a first opening 301 on the side near the second fixing plate 112. The air inlet end of the motor cover 610 is connected to the second cavity through the first opening 301, and the air outlet end is connected to the air outlet 101. The airflow enters from the air inlet, flows through the second cavity, and then flows through the first opening 301 to the motor 60 to complete the heat dissipation of the motor 60. After passing through the space formed by the motor cover 610, it is discharged to the outside of the equipment through the air outlet 101. Due to the presence of the motor cover 610, the diffusion and loss of cooling airflow are effectively prevented, improving airflow utilization and cooling efficiency. At the same time, this structure can also play a certain role in dust prevention and protection, preventing external impurities from directly contacting the motor surface and extending the service life of the motor.

[0103] Please see Figure 5 , Figures 19 to 22 , Figures 26 to 30 As shown, in this embodiment, the air inlet includes a first air inlet 201, which is located at the bottom of the housing corresponding to the second cavity 120, specifically on the lower cover 12. The air outlet 101 is located on the lower housing 15. After the snow sweeper is started, the fan on the motor 60 rotates, driving airflow. External cold air first enters the second cavity 120 through the first air inlet 201 to cool the control module 30. Subsequently, the airflow flows to the motor 60 through the first opening 301 on the side of the electrostatic shielding bracket near the second fixed plate 112, where it is forcibly cooled, carrying away the heat generated during operation. Finally, the airflow carrying heat is discharged to the outside of the snow sweeper through the air outlet 101 on the lower housing 15, completing the entire heat dissipation cycle. The design of the above-mentioned heat dissipation air duct fully considers the heat load distribution characteristics of the control module 30 and the motor 60, achieving the goal of centralized and efficient heat dissipation of multiple components, avoiding performance degradation or equipment failure caused by local overheating, and improving the operational stability and service life of the snow sweeper under complex working conditions.

[0104] Please see Figure 5 , Figures 19 to 22 , Figures 26 to 30As shown, in this embodiment, the first air inlet 201 is located on the lower cover 12 away from the first opening 301. Specifically, the first air inlet 201 is located on the lower cover 12 near the first fixing plate 111. The control module 30 is mounted on the electrostatic shielding bracket 30 and located near the second fixing plate 112. Air enters the second cavity 120 from the first air inlet 201, flows through the control module 30 first, and then flows through the motor. It can also be understood that keeping the control module 30 away from the first air inlet 201 prevents water from splashing in from the first air inlet 201, thus avoiding potential safety hazards to the control module 30 and improving safety.

[0105] Please see Figures 4 to 6 , Figure 14 , Figures 19 to 22 , Figures 26 to 30 As shown, in this embodiment, the electrostatic shielding bracket 30 has a fourth opening 310 on the side opposite to the lower cover 14. The fourth opening 310 is connected to the internal space of the frame 10, so that the first air inlet 201 and the inside of the frame 10 form an air flow channel, which helps to dissipate the heat generated during the operation of the control module 40 in a timely manner. At the same time, the fourth opening 310 can also be used as a wiring port for wiring.

[0106] Please see Figure 5 , Figures 19 to 22 , Figures 26 to 30 As shown, in this embodiment, the air inlet also includes a second air inlet 202. Specifically, the second air inlet 202 is disposed on the lower housing 15, located on both sides opposite to the air outlet 101 at the bottom of the lower housing 15. Further, a second opening 102 is also provided at the bottom of the lower housing 15, which connects the first chamber 110 and the second chamber 120. Thus, the second air inlet 202, the second opening 102, the first opening 301, and the air outlet 101 are sequentially connected. In actual operation, when the snow sweeper is working, external cold air can also enter the first chamber 110 through the second air inlet 202 located at the front end of the lower housing 15, and then pass through the second air inlet 202 in the middle of the lower housing 15. The airflow flows into the second cavity 120 through the opening 202. At this time, the cooling airflow directly cools the control module 30 installed in the second cavity 120, especially focusing on cooling the area where high-power electronic components and heat dissipation components 31 are located. Then, the airflow flows from the first opening 301 to the motor 60, where it is forced to be cooled by air, taking away the heat generated during operation. Finally, the airflow is discharged to the outside of the snow sweeper through the air outlet 101 located on the lower housing 15, thus completing the entire heat dissipation process. This significantly reduces the heat load of the environment where the control module 30 is located, avoiding the system's protective frequency reduction or shutdown caused by excessively high local temperatures, and effectively improving the operational stability and reliability of the snow sweeper under complex working conditions.

[0107] Please see Figure 4, Figure 27 and Figure 28 As shown, in this embodiment, the snowplow also includes a battery assembly 80, which includes a battery pack compartment and at least one battery pack installed within the compartment, providing power to the entire machine. The battery assembly 80 is installed within the first cavity 110 and located in the vicinity of the control module 30 to optimize the overall spatial layout. In particular, to improve the thermal management capability of the battery pack during high-load operation and prevent safety hazards and performance degradation caused by overheating, a through hole is provided at the bottom of the battery assembly 80, corresponding to the second opening 102 on the lower housing 15. Correspondingly, a battery pack air inlet is provided on the side of the battery pack installed within the battery pack compartment. Through the above structural design, after the external cooling airflow enters the equipment, some of the airflow can further flow into the battery pack compartment through the through hole at the bottom of the battery assembly 80, and then effectively dissipate heat from the battery pack through the battery pack air inlet on the side of the battery pack. Specifically, cold air enters the device through the second air inlet 202 located at the front end of the lower housing 15, and then flows into the first cavity containing the control module 30 through the second opening 102 in the middle of the lower housing 15. After cooling the control module 30, part of the airflow enters the battery pack compartment through the through-hole at the bottom of the battery assembly 80, providing forced ventilation cooling to that area of ​​the battery pack. This structural design allows the device to simultaneously serve three key heat-generating components: the control module 30, the motor 60, and the battery pack. This achieves the goal of centralized and efficient heat dissipation for multiple components, avoiding issues such as temperature protection failures, performance degradation, or safety hazards caused by localized overheating. It significantly improves the stability and safety of the snow sweeper under prolonged high-load operation.

[0108] Please see Figure 4 , Figure 27 and Figure 28 As shown, in this embodiment, the battery assembly 80 is installed inside the housing and located behind the front housing 20. The battery, acting as a weight, is placed in the middle to rear, which helps to control the overall center of gravity of the machine between the roller shaft 51 and the wheel axle 91. Specifically, the angle α between the insertion / removal direction of the battery pack within the battery assembly 80 and the ground satisfies: 0°≤α≤100°. Further, this angle α satisfies the following relationship: 45°≤α≤90°, meaning that the battery assembly 80 forms an angle α with the ground. This inclined insertion / removal path effectively avoids the front housing 20 or other structural components located at the front of the snow sweeper, preventing operational difficulties caused by space constraints when replacing the battery.

[0109] Please see Figure 4 , Figures 26 to 28 , Figure 36 and Figure 37As shown, in this embodiment, the battery module compartment is provided with at least one battery pack cavity 81. When the battery module 80 has one battery pack cavity 81, the voltage of the battery pack is 60V or 80V. When the battery module 80 has two battery pack cavities 81, the total voltage of the two battery packs is 60V or 80V, or the voltage of a single battery pack is one of 24V, 40V, and 48V. That is, this embodiment supports multiple battery specifications, which is convenient for users to replace or use existing battery packs.

[0110] Please see Figure 5 , Figures 19 to 22 , Figures 26 to 30 As shown, in this embodiment, the air inlet also includes a third air inlet 203. Specifically, the third air inlet 203 is located on the front housing 20 near the first fixed plate 111. The third air inlet 203 is connected to the second cavity. The heat dissipation bracket 50 has a third opening 502 at one end near the first fixed plate 111. The third air inlet 203 is connected to the second cavity through the third opening 502. In actual operation, when the snow sweeper is working, external cold air first enters the equipment through the third air inlet 203, and then enters the second cavity through the third opening 502, effectively cooling the control module 30 in the second cavity. Subsequently, the cold air continues to flow through the first opening 301 to the motor 60, and further dissipates and cools the motor 60. Finally, the air carrying heat is discharged to the outside of the snow sweeper through the air outlet 101 on the lower housing 15, thus completing the entire heat dissipation process.

[0111] Please see Figure 2 , Figures 31 to 35As shown, in this embodiment, the snowplow also includes a snow-throwing channel 240 communicating with the snow inlet 260. The snow-throwing channel 240 is used to smoothly discharge snow that has been broken by the snow cutter 53 and thrown by the snow-throwing paddle 52 to the outside of the equipment. To ensure that the snow can pass through smoothly, the inner wall of the snow-throwing channel 240 is designed as a smooth surface. Furthermore, the inner wall of the front housing 20 is also designed as a smooth surface to ensure that the snow can be quickly broken by the snow cutter 53 and discharged to the outside of the equipment through the snow-throwing channel 240 after entering the equipment. Furthermore, the snow inlet 260, 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 front 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 240, the inner wall of the front housing 20, and the inner wall of the snow inlet 260, 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.

[0112] Please see Figures 31 to 35As shown, in this embodiment, the front housing 20 also includes a snow shield 250, which is arranged opposite to the snow inlet 260 and covers at least a portion of the snow inlet 260. 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 250 is installed at the intersection of the snow inlet 260 and the snow throwing channel 240, specifically above or to the side of the front end of the blade assembly 50, forming a physical barrier to prevent snow from splashing outwards during the high-speed rotation of the snow cutter blade 53 and the snow thrower 52. The snow shield 250 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 240, preventing it from being sprayed directly forward. During snow removal operations, due to the high-speed rotation of the snow cutter blade 53 and the snow thrower 52, some snow may be thrown out in front of the equipment due to centrifugal force, obstructing the operator's view and even causing safety accidents. By installing the snow shield 250, this splashing snow can be effectively blocked, significantly improving the safety performance of the equipment. The snow shield 250 not only provides protection but also functions as a deflector; its sloping surface helps redirect snow that might otherwise overflow into the snow-throwing channel 240, 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 the burden of subsequent cleanup. 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.

[0113] Please see Figures 31 to 35 As shown, in this embodiment, the snow inlet 260 has a conical structure, meaning the diameter of the snow inlet 201 gradually decreases along the second direction Y, which is the direction from the bottom of the front housing 20 to the top surface of the front 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 50. 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 260 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 260 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.

[0114] Please see Figures 31 to 35 As shown, in this embodiment, the position of the snow-throwing paddle 52 corresponds to the snow inlet 260, ensuring that snow can smoothly enter the equipment and be effectively collected and thrown out. The width WB of the snow-throwing paddle 52 is less than the maximum width WA of the snow inlet 260. This design breaks with the traditional snowplow design where the width of the snow-throwing paddle is equal to or close to the width of the snow inlet. This design allows the snow inlet 260 to have more space for snow entry in the lateral direction, thereby improving the smoothness of snow entering the equipment, 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 52 is slightly smaller than the maximum width of the snow inlet 260, by optimizing the rotation angle of the roller cutter, the orientation of the snow-throwing channel 240, and the arrangement of the snow-sweeping blade 53, it can still ensure effective capture and uniform distribution of snow, without affecting the snow-throwing efficiency. Understandably, by designing the width of the snowplow 52 to be less than the maximum width of the snow inlet 260, the technical effects of smooth snow entry, efficient snow throwing, and structural stability are achieved. This solves the problems of poor snow entry and easy clogging in existing snow removal equipment, and improves the adaptability and reliability of the equipment.

[0115] Please see Figures 31 to 35As shown, in this embodiment, the structural design of the blade assembly 50 is optimized, with particular emphasis on the rotation sweeping angle range of the snow winch blade 53 to improve the equipment's working efficiency and snow removal capacity. Specifically, the blade assembly 50 also includes snow winches 53 located on both sides of the snow-throwing paddle 52. The snow winches 53 are fixedly connected to the roller shaft 51 and the snow-throwing paddle 52, forming a single working unit. In this embodiment, the rotation sweeping angle range of the snow winch blade 53 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 blade 53 within a reasonable range, the snow collection efficiency can be significantly improved. A smaller angle allows the snow winch blade 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 52. A larger angle increases the coverage area of ​​the snow winch blade, 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 cause the equipment to be overloaded, 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 blade, the service life of the equipment can be extended while ensuring working efficiency and reducing maintenance costs. That is, in this embodiment, by optimizing the sweeping angle of the snow winch blade 53, 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.

[0116] Please see Figures 31 to 35As shown, in this embodiment, the front housing 20 also includes an inner surface 220 adjacent to the cutter assembly 50. A predetermined gap is provided between the outer diameter of the cutter assembly 50 and the inner surface 220, that is, a predetermined gap is provided between the outer contour of the rotation path of the cutter assembly 50 and the inner surface 220. For example, along the radial direction of the cutter assembly 50, the distance L2 between the outer diameter of the cutter assembly 50 and the inner wall of the front housing 20 satisfies: 2mm≤L2≤6mm. A reasonable L2 value ensures that the snow shovel 53 maintains an appropriate distance from the inner wall of the front 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.

[0117] Please see Figures 31 to 35 As shown, in this embodiment, a groove 210 is provided on the inner surface 220 of the front housing 20. Specifically, the height H1 of the groove 101 from the bottom of the front housing 20 is less than or equal to the height H2 between the bottom of the front housing 20 and the highest point of the snow cutter 33. In this embodiment, grooves 210 are symmetrically provided on both sides of the snow inlet 260. Furthermore, the grooves 210 extend from a position near the side of the front housing 20 to the snow inlet 260 and communicate with the snow inlet 260. The grooves 210 can effectively reduce the snow throwing resistance, allowing the grooves 210 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 210 located on one side of the snow inlet 260 can be designed as one, two, or more, which helps snow to enter the snow throwing channel 240 smoothly and reduces the retention of snow on the inner wall of the cavity.

[0118] Please see Figures 31 to 35 As shown, in this embodiment, the radial distance design between the cutter assembly 50 and the groove 210 is further optimized to ensure efficient operation and structural stability of the equipment. Along the radial direction of the cutter assembly 50, the distance L1 between the outer diameter of the cutter assembly 50 and the bottom of the groove 210 satisfies: L1 > 10 mm. This larger radial distance ensures that the snow winch 53 has sufficient working space, preventing the groove 210 from malfunctioning due to insufficient clearance, which could cause snow, stones, or other debris to get stuck between the groove 210 and the cutter assembly 50. This ensures that the groove 210 effectively guides snow or stones into the snow-throwing channel, reducing snow accumulation on the inner wall of the cavity.

[0119] Please see Figure 16 , Figure 17 and Figure 18As shown, in this embodiment, the snow winch 53 is a one-piece molded structure, including a main body 531 and a first blade 532 and a second blade 533 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 53 is manufactured using a one-piece molding process. The main body 531 serves as the central support structure of the entire snow winch 53, connecting the roller shaft 51 and bearing the torque and impact force generated during rotation. The first blade 532 and the second blade 533 extend outward from the main body 531 to form functional components for cutting and breaking snow. The two blades are distributed at a certain angle on the main body 531 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.

[0120] Please see Figure 16 , Figure 17 , Figures 31 to 35 As shown, in this embodiment, the total axial projection angle γ of the first blade 532 and the second blade 533 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 53 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 532 and the second blade 533, the snow can be guided towards the snowplow 52 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.

[0121] Please see Figure 16 , Figure 17 and Figure 18As shown, in this embodiment, the structural design of the snow winch 53 is further optimized. Connecting plates 534 are provided on both sides along its axial direction, and these connecting plates 534 are fixedly connected to the first blade 532 and the second blade 533, respectively. This structural design effectively enhances the overall rigidity and deformation resistance of the snow winch, making it particularly suitable for snow sweeping operations under high-speed rotation conditions. The connecting plates 534 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 53 along its axial direction. In this embodiment, the connecting plates 534 are located between the outer ends of the first blade 532 and the second blade 533, forming a closed or semi-closed frame structure. The connecting plates 534 can be firmly connected to the first blade 532 and the second blade 533 through welding, bolting, riveting, or integral molding, ensuring that they will not loosen or fall off during high-speed rotation. The connecting plates 534 not only provide support and reinforcement but also guide the snow flow to a certain extent, improving the overall working performance of the equipment.

[0122] Understandably, since the snow auger 53 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 534 on both axial sides, significantly improves the overall rigidity of the snow auger, preventing structural deformation caused by uneven stress. The introduction of connecting plates 534 in this embodiment gives the snow auger 53 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 augers are prone to fatigue damage due to stress concentration under prolonged high-speed operation, the presence of connecting plates 534 in this embodiment effectively disperses the stress points, preventing excessive local stress, thereby extending the service life of the snow auger and reducing maintenance frequency.

[0123] Please see Figure 16 , Figure 17 and Figure 18As shown, in this embodiment, the snowplow 52 includes a main body 521 and extension plates 522 located on both sides of the main body. The extension plates 522 are fixedly connected to the snow cutter blades 53. The main body 521 serves as the main structure of the snowplow 52, ​​used to be mounted on the roller shaft 51, and to withstand the centrifugal force and impact force generated during rotation. The extension plates 522 are respectively disposed on both sides of the main body 521, extending outward to form functional surfaces with a certain arc or inclination angle, used to capture and accelerate snow accumulation, causing it to be thrown out in a specific direction. The extension plates 522 are fixedly connected to the snow cutter blades 53 by welding, screwing, or integral molding, so that the entire blade assembly 50 forms a stable rotating whole. Specifically, the two extension plates 522 located on both sides of the main body are respectively connected to the snow cutter blades 53 on both sides of the snowplow 52. Specifically, the snowplow includes two snowplows 52, which are used for two first blades 532 and two second blades 533, respectively. In this embodiment, the two extension plates 522 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, so that it can be accurately thrown to the snow entry 260.
