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. During operation, especially in winter, snowplows are prone to generating a large amount of static electricity due to factors such as friction. For example, the friction between snow and the surface of the cavity generates a large amount of static electricity. The accumulation of static electricity can easily damage the electronic structure of the snowplow, such as the motor and control module, resulting in high maintenance costs. Furthermore, a large amount of static electricity accumulation can also easily cause electric shock injuries to people. Utility Model Content

[0048] 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.

[0049] 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.

[0050] 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.

[0051] It is understandable that snowplows, especially during winter use, are prone to generating a large amount of static electricity due to friction and other factors. For example, the friction between snow and the surface of the snowplow housing generates a significant amount of static electricity. The accumulation of static electricity can damage the electronic components of the snowplow, such as the motor and control module, leading to high maintenance costs. Furthermore, the large accumulation of static electricity can also pose a risk of electric shock. Therefore, this invention proposes a snowplow to address the problems of existing snowplow equipment generating a large amount of static electricity during use due to snow accumulation and friction on the housing, resulting in damage to the motor or control module, high maintenance costs, and the risk of electric shock.

[0052] Please see Figures 1 to 22 As shown, in this embodiment, the snowplow includes a frame 10, a housing 20, a support, a control module 40, and a blade assembly 50. The housing 20 is mounted on the frame 10, and at least its front end is provided with a snow inlet 201. The blade assembly 50 is at least partially housed within the housing 20 and is rotatably disposed relative to the frame 10. The control module 40 is connected to the frame 10 via the support, which is an electrostatic shielding support 30 made of conductive material, such as a metal electrostatic shielding support. The bottom of the frame 10 is designed with a near-ground end, and the frame 10 is configured to conduct static electricity on the electrostatic shielding support 30 to the near-ground end and release it. In this embodiment, by placing the control module 40 on the electrostatic shielding bracket 30, electrostatic interference generated by friction from the housing 20, the tool assembly 50, and other parts can be effectively isolated, 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 frame 10, static electricity entering the housing can be quickly guided to ground and released, thus avoiding static accumulation and discharge. In this embodiment, because the control module 40 is protected by both physical and electromagnetic means, the damage rate of electronic components due to electrostatic breakdown is significantly reduced, improving the stability and service life of the entire machine. Moreover, 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, enhancing operator safety.

[0053] 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 equipment. The frame 10 includes a fixing plate, which is installed on the side of the 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 housing 20, used to enhance the overall structural strength and provide an installation base for other components. The 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 frame 10 and is fixedly connected to the first fixing plate 111, the second fixing plate 112, and the 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.

[0054] Please see Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figure 16 and Figure 22As shown, in this embodiment, the electrostatic shielding bracket 30 is located on the rear side of the housing 20, i.e., the side opposite to the blade assembly 50. The electrostatic shielding bracket 30 includes a first end 311, 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 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.

[0055] 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 discharge path, preventing electrostatic accumulation from interfering with or damaging the internal circuitry, and effectively enhancing the shielding effect.

[0056] Please see Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 22 As shown, in this embodiment, a bottom cover 14 is provided at the bottom of the frame 10. The bottom cover 14 is arranged opposite to the top surface 314 of the electrostatic shielding bracket 30 and covers the control module 40 to protect the internal control module 40. In this embodiment, the bottom cover 14 is detachably connected to the frame 10 and the 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 bottom cover 14 when needed to inspect, replace, or maintain the control module 40, improving the maintainability and ease of use of the equipment.

[0057] Please see Figure 2 , Figure 3 , Figure 6 , Figure 11 , Figure 14 and Figure 16As shown, in this embodiment, the snowplow further includes a blade assembly 50, which is at least partially housed inside the housing 20 and is used to crush and throw snow. The blade assembly 50 includes a roller shaft 51, a snow-throwing paddle 52, and a snow-sweeping blade 53. The roller shaft 51 is the core transmission component of the blade 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 mounted on the roller shaft 51 and is used to throw out snow that enters the equipment. The snow-sweeping blade 53 is disposed on both sides of the snow-throwing paddle 52 and is used to crush and agitate the snow to improve snow entry efficiency.

[0058] Please see Figure 2 , Figure 3 , Figure 6 , Figure 11 , Figure 14 and Figure 16 As shown, in this embodiment, the snowplow also includes a motor 80, which is mounted on the frame 10 and is connected to the blade assembly 50 via a transmission connection, specifically to the roller cutter shaft 51, for driving the roller cutter shaft 51 to rotate, thereby driving the snow-throwing paddle 52 and the snow-sweeping blade 53 to rotate synchronously. Through the above structural design, the blade assembly 50 can efficiently complete the tasks of collecting, crushing, and throwing snow, ensuring the continuity and efficiency of snow removal operations.

[0059] Please see Figure 18 , Figure 19 , Figure 20 and Figure 21 As shown, in this embodiment, the motor 80 is fixedly mounted on the frame 10, which is configured to conduct static electricity from the motor 80 to the near-ground end for release, thus preventing static electricity accumulation from damaging the motor 80. Specifically, the motor 80 is mounted on one of the fixing plates, for example, on a second fixing plate 112, through which static electricity from the motor 80 can be conducted to the near-ground end of the frame 10 for release. Further, in this embodiment, the motor 80 includes a motor bracket 81, which is fixedly connected to the second fixing plate 112. Furthermore, the motor bracket 81 and the second fixing plate 112 are in surface contact and fixedly connected. 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 80 is less prone to poor contact due to vibration during equipment operation, thus improving connection stability, ensuring good conductivity between the motor and the fixing plate, contributing to the stability of the static electricity conduction path, and preventing static electricity accumulation from interfering with or damaging the motor.

[0060] Please see Figure 2 , Figure 3 , Figures 6 to 14As 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 electrostatic 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 static electricity release path between the electrostatic shielding bracket 30, the first fixed plate 111, the second fixed plate 112, and the hobbing shaft 51, allowing 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.

[0061] Please see Figure 2 , Figure 3 , Figures 6 to 14As shown, in this embodiment, a bearing assembly 511 is sleeved at the end of the hob shaft 51. The bearing assembly 511 ensures the smooth rotation of the cutter assembly 50. The fixing plate is at least partially in contact with the bearing assembly 511, 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 housing 20, and a first protrusion 1111 is formed on a part of the first fixing plate 111 facing away from the housing 20. That is, the side of the first fixing plate 111 facing away from the housing 20 is recessed to form an accommodating space. The recessed part of the first fixing plate 111 facing away from the housing 20 appears as the first protrusion 1111. The bearing assembly 511 is installed in the accommodating space, so that the inner surface of the first protrusion 1111 contacts and connects with the bearing assembly 511. The first protrusion 1111 restricts the position of the bearing assembly 511 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 30 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.

[0062] Please see Figure 2 , Figure 3 , Figures 6 to 14As shown, in this embodiment, the snowplow further includes a moving wheel assembly, which includes an axle 61 and moving wheels 62 located on both sides of the frame 10. The two ends of the axle 61 are connected to fixed plates, namely a first fixed plate 111 and a second fixed plate 112. The moving wheels 62 are connected to the axle 61 to support the entire machine and enable the snowplow to move forward or backward. The axle 61 is made of metal and has good electrical conductivity, providing a physical path for static 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 61 also maintains good conductive contact with the first fixed plate 111 and the second fixed plate 112, so that the electrostatic shielding bracket 30, the first fixed plate 111, the second fixed plate 112, and the axle 61 form a static discharge path. 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 61 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 axial surface of the wheel axle 61. This arc-shaped structure forms a stable connection with the wheel axle 61 and increases the electrostatic conduction area, ensuring electrical conduction between the wheel axle 61 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.

[0063] Please see Figure 2 , Figure 3 , Figures 6 to 14As 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 push rod, 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 housing 20, and the lower push rod 70 is located within the grooves 315. This allows the axial surfaces of the electrostatic shielding bracket 30 and the lower push rod 70 to make surface contact, thereby increasing the electrostatic conduction area and significantly improving the conductivity and stability of the electrostatic conduction path. This effectively enhances the electromagnetic compatibility and anti-static interference capability of the entire device.

[0064] Please see Figure 2 , Figure 3 and Figure 18As shown, in this embodiment, the frame 10 also includes a metal guide plate 11 and feet 12. The metal guide plate 11 is installed on both sides of the housing 20 and located inside the housing 20. The metal guide plate 11 is at least partially in contact with the bearing assembly 511. 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 housing 20. That is, the metal guide plate 11 is recessed inward from the 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 housing 20. The bearing assembly 511 is installed in this receiving space, so that the inner surface of the second protrusion 1101 contacts and connects with the bearing assembly 511. The second protrusion 1101 and the first protrusion 1111 restrict the axial position of the bearing assembly 511, 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.

[0065] 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 component with conductive function, preferably made of a material 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.
