[0002] During the snowy season, snow accumulation often causes road blockages, making it impossible for vehicles to travel normally and causing great inconvenience to drivers and pedestrians. In order to ensure unobstructed roads, a small snowplow has been developed. This machine not only sweeps snow quickly and efficiently, but also has low snow removal costs and does not produce environmental pollution, and has been rapidly promoted and applied.

[0003] In existing technologies, small snowplows suffer from short operating time and limited functionality. To address these issues, the snowplow head and sweeper head are designed to be detachable and interchangeable, enabling the snowplow to sweep both snow and ground, greatly expanding its functionality. However, this detachable and interchangeable structure is complex, difficult to replace, and requires tools. Furthermore, the user must access the connection between the head and the body to perform the replacement, making the operation inconvenient and causing inconvenience for the user.

[0004] Therefore, there is an urgent need to develop a snow sweeper that can overcome the above-mentioned defects of existing snow sweepers, with a simple and reasonable structure and easy operation. While satisfying the requirements of the snow sweeper head having multiple functions and being detachable and interchangeable, the disassembly structure is more convenient and quick, eliminating the need for users to disassemble and interchange the head at the connection point between the head and the body of the snow sweeper. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Figure 1 is a structural schematic diagram of this utility model, Figure 2 is an example, and Figure 3 is an example. As shown in the figures, the snow sweeper with a quick-detachable head in this embodiment includes a body connecting seat 1 and a head connecting seat 2. The body connecting seat 1 has a head connecting part at the top and a connecting shaft 3 at the bottom. The head connecting part has an upward-opening slot 4. The head connecting seat 2 has a retaining shaft 6 at the top that connects to the slot 4. The bottom of the head connecting seat 2 has a connecting hole through which the connecting shaft 3 can pass to form a connection. The body connecting seat 1 can be made of metal casting or engineering plastic injection molding, and its structural strength must meet the stress requirements during snow sweeping operations. The head connecting part and the body connecting seat 1 can be an integrally formed structure or a separate assembly structure. The opening direction of the slot 4 can be set vertically upward, or it can be designed at an inclined angle according to actual assembly requirements. The fit between the retaining shaft 6 and the slot 4 can adopt a rectangular, trapezoidal, or other anti-detachment structure. The connecting shaft 3 can be a solid shaft or a hollow shaft structure, and its diameter must match the connecting hole. The connection hole can be designed as a through hole or a blind hole, and a wear-resistant bushing can be installed inside the hole to improve service life.

[0025] The quick-connection of the machine head and body is achieved through the quick-connection of the slot 4 and the shaft 6, and the through-hole fixing of the connecting shaft 3. The slot 4 and shaft 6 provide initial positioning and anti-rotation functions, while the connecting shaft 3, after passing through the connecting hole, forms the main load-bearing connection. This structural design eliminates the need for tools during machine head disassembly; the operator simply pulls out the connecting shaft 3 to separate the machine head. This solves the problems of complex disassembly operations and the need for special tools in existing technologies. The structure is simple and reliable, and the disassembly operation is more convenient, effectively improving the ease of use of the snow sweeper.

[0026] In this embodiment, the connecting holes include a first connecting hole 7 and a second connecting hole 8 facing each other. The first connecting hole 7 and the second connecting hole 8 are circular holes. The second connecting hole 8 has a mounting notch 9 smaller than the diameter of the circular hole. The connecting shaft 3 has a mounting groove 10 formed by a radial inward recess. In use, the connecting shaft 3 is inserted into the mounting notch 9 through the mounting groove 10. After insertion, the connecting shaft 3 can move axially until the shaft passes through the first connecting hole 7 and the second connecting hole 8. The mounting notch 9 can be designed as a U-shaped groove or a V-shaped groove structure, with a width slightly smaller than the diameter of the connecting shaft 3 but larger than the width of the mounting groove 10. The mounting groove 10 can be an annular groove formed on the surface of the connecting shaft 3 by milling or stamping. Its depth and width must ensure a stable temporary engagement with the mounting notch 9. As a preferred embodiment, the first connecting hole 7 and the second connecting hole 8 are coaxially designed, with a distance between them slightly larger than the effective working length of the connecting shaft 3, so that the connecting shaft 3 can pass through both connecting holes simultaneously when moving axially.

[0027] The pre-positioning and quick guiding functions of the connecting shaft 3 are achieved through the cooperation of the mounting notch 9 and the mounting groove 10. When the mounting groove 10 of the connecting shaft 3 is aligned with the mounting notch 9, only a small axial force is needed to complete the initial fixation. Subsequently, the connecting shaft 3 is fully inserted into the first connecting hole 7 and the second connecting hole 8 by axial sliding. Compared with the traditional installation method that requires perfect alignment of the two connecting holes, this design significantly reduces the assembly accuracy requirements, and the head connecting seat 2 and the body connecting seat 1 can be quickly aligned and locked without the need for tools during operation.

[0028] In this embodiment, baffles I11 are provided on both sides of the fuselage connecting seat 1, and baffles II12 are provided on both sides of the head connecting seat 2. Baffles I11 and II12 can be formed by stamping metal sheets or injection molding engineering plastics, with a preferred thickness range of 1.5-3mm. Baffles I11 and the fuselage connecting seat 1 can be fixed by welding, bolting, or integral casting, while baffles II12 and the head connecting seat 2 use the same connection method. As a preferred embodiment, the installation positions of baffles I11 and II12 are symmetrically distributed on both sides of the connecting seat, with a height flush with the main body of the connecting seat. Baffle I11 can extend to cover the installation area of ​​the connecting shaft 3, while baffle II12 correspondingly covers the connecting hole area. Specifically, baffle II12 can be designed as an L-shaped structure, with the vertical portion used to limit the lateral displacement of the head connecting seat 2 and the horizontal portion used to block snow splashing.

[0029] By installing baffle assemblies on both sides of the connecting seat, the problems of snow accumulation and component collision at the connection point between the snowplow body and the head during operation are effectively solved. The double protective structure formed by baffle I11 and baffle II12 not only prevents external snow from entering the connecting mechanism and affecting disassembly operations, but also avoids rigid collision between the connecting shaft 3 and the connecting hole under vibration conditions. Compared with existing technologies, this structure does not require additional fasteners, and significantly improves the protective performance and operational stability of the connecting parts while maintaining the quick disassembly function.

[0030] This embodiment also includes a snap-fit ​​control assembly, which includes a bushing 13 disposed between the baffles I 11. The connecting shaft 3 passes through the bushing 13 and is subjected to a preload in the working position. The bushing 13 can be made of metal or high-strength plastic, and its inner diameter is slightly larger than the diameter of the connecting shaft 3 to ensure smooth axial sliding. The preload can be achieved by a helical spring, disc spring, or elastic rubber component, wherein a preferred embodiment is a helical spring sleeved on the connecting shaft 3 with its two ends abutting against the drive rod 15 and the end of the bushing 13, respectively. The bushing 13 is fixed to the baffles I 11 by welding, bolting, or snap-fit ​​connection, wherein bolting facilitates maintenance and adjustment. The direction of the preload is configured to always push the connecting shaft 3 toward the first connecting hole 7 and the second connecting hole 8, thereby ensuring that the connecting shaft 3 automatically maintains the connected position in the working state.

[0031] The preload maintains a stable connection of the connecting shaft 3, preventing accidental disengagement due to vibration during snow removal operations. When disassembly is required, the connection can be released by overcoming the preload and pulling the drive rod 15; the operation is tool-free and can be completed with one hand. The bushing 13 structure provides radial restraint to the connecting shaft 3, preventing wear caused by lateral swaying, while the slotted design 14 allows for precise control of the drive rod 15's movement trajectory. Compared to existing technologies that require tools for disassembly, this solution significantly improves the convenience and reliability of head replacement.

[0032] In this embodiment, when the connecting shaft 3 is in the working position, the connecting shaft 3 passes through the first connecting hole 7 and the second connecting hole 8 on the head connector 2, connecting the body connector 1 and the head connector 2. After the connecting shaft 3 is embedded into the mounting notch 9 through the mounting groove 10, it can move axially until the shaft passes through the first connecting hole 7 and the second connecting hole 8, thereby achieving a stable connection between the body connector 1 and the head connector 2. As a preferred embodiment, the axial movement of the connecting shaft 3 can be achieved by the drive rod 15. The drive rod 15 is set in the slot 14 of the bushing 13 and is driven by the cable assembly. The drive rod 15 is connected to the elastic element 18, and the elastic element 18 applies a preload to keep the connecting shaft 3 in the working position. The insertion of the connecting shaft 3 can be achieved in several ways. For example, the drive rod 15 can be designed as a manual operating lever, allowing the axial movement of the connecting shaft 3 to be achieved by manual pushing and pulling; alternatively, the drive rod 15 can be connected to an electric push rod, enabling automated operation via motor drive; furthermore, the drive rod 15 can also be connected to a hydraulic cylinder or pneumatic device, achieving rapid response via hydraulic or pneumatic drive. The cable assembly allows the operator to achieve drive without direct contact with the connecting shaft 3, making operation more convenient.

[0033] The axial movement of connecting shaft 3 enables a quick connection between the machine body and the machine head, solving the problems of complex disassembly and interchange operations and the need for tools in existing technologies. Compared with existing technologies, this solution has a simple and reasonable structure, is easy to operate, and allows for quick disassembly and installation of the machine head without the user having to operate directly at the connection point, significantly improving user convenience.

[0034] In this embodiment, the bushing 13 has an axially oriented slot 14, and the connecting shaft 3 has a drive rod 15 located within the slot 14. The drive rod 15 drives the connecting shaft 3 to move axially. Both ends of the connecting shaft 3 protrude from the bushing 13, and the length of the protruding portion is less than the length of the slot 14. The slot 14 is a strip-shaped through hole penetrating the side wall of the bushing 13, and its length direction is parallel to the axis of the bushing 13. The drive rod 15 can be fixed to the middle of the connecting shaft 3 by means of a cylindrical pin or a square key, and its two ends extend to the outside of the slot 14 for operation. As a preferred embodiment, the width of the slot 14 is slightly larger than the diameter of the drive rod 15 to ensure smooth axial movement without significant radial wobble. The length of the end of the connecting shaft 3 protruding from the bushing 13 is controlled within 1 / 3 of the length of the slot 14, which ensures connection stability and avoids interference movement.

[0035] The slot 14 and the drive rod 15 work together to achieve controllable axial displacement of the connecting shaft 3 within the bushing 13. When the machine head needs to be disassembled, the drive rod 15 is pulled by an external operating mechanism to allow the connecting shaft 3 to exit from the connecting hole of the machine head connecting seat 2; during installation, the drive rod 15 is released, and the preload force pushes the connecting shaft 3 to automatically reset and complete the connection. Compared with the existing structure that requires tools for disassembly, this design only requires unidirectional force to complete the operation, and the position of the drive rod 15 can be ergonomically set in an easily accessible location, significantly improving the convenience of machine head replacement. The precise design of the slot 14 length ensures the working stroke of the connecting shaft 3 while maintaining connection strength by limiting the protruding length.

[0036] This embodiment also includes a cable assembly, which comprises a cable 16 and a cable support 17. One end of the cable 16 is connected to a drive rod 15, and the other end is connected to the push handle 22 of the snowplow. The drive rod 15 can be driven by the cable, thereby driving the connecting shaft 3 to move axially. The cable support 17 is used to fix the direction of the cable 16, ensuring that the cable 16 remains stable during pulling. The cable 16 can be made of flexible materials such as steel wire rope or nylon rope. The cable support 17 can be set on the body connecting seat 1 or the push handle 22, and the specific position is determined according to the actual installation requirements. As a preferred embodiment, the cable support 17 can be designed as an adjustable structure to facilitate adjustment of the tension of the cable 16.

[0037] The cable assembly works by the operator pulling the cable 16 on the push handle 22, which moves the drive rod 15 and then the connecting shaft 3 axially. The movement of the connecting shaft 3 disengages the mounting slot 10 from the mounting notch 9, allowing for quick separation of the head unit connecting seat 2 from the body connecting seat 1. The length and direction of the cable 16 can be adjusted according to the specific structure of the snowplow to ensure that the operator can complete the disassembly operation while pushing the handle 22, without directly contacting the connection between the head and body. Therefore, the cable assembly makes head unit disassembly more convenient; the operator does not need to operate at the connection between the head and body, but only needs to pull the cable 16 on the push handle 22 to complete the disassembly. This design solves the problem of inconvenient disassembly operations in existing technologies, improving the user experience. Furthermore, the cable assembly has a simple structure, is easy to install and maintain, and is suitable for the modification and application of various small snowplows.

[0038] In this embodiment, the preload is applied through an elastic element 18. One end of the elastic element 18 is connected to the drive rod 15, and the other end is on the body connecting seat 1. The elastic element 18 can be a component with elastic deformation capabilities, such as a helical spring, disc spring, or rubber elastomer. As a preferred embodiment, the helical spring is sleeved on the outside of the connecting shaft 3, with one end fixed to the annular boss of the drive rod 15 and the other end abutting against the limiting baffle of the body connecting seat 1. When the drive rod 15 moves axially under the action of an external force, the spring is compressed to generate a preload; after the external force is removed, the spring recovers its deformation and pushes the drive rod 15 to reset. Furthermore, the elastic element 18 can also be two sets of symmetrically arranged tension springs, respectively connected between the two sides of the drive rod 15 and the body connecting seat 1. In addition, an adjusting screw can be provided on the body connecting seat 1, and the magnitude of the preload can be adjusted by changing the screw's screw insertion depth.

[0039] When the operator pulls the drive rod 15 via the cable assembly, the elastic element 18 accumulates elastic potential energy; after releasing the cable 16, the elastic element 18 releases the potential energy, allowing the connecting shaft 3 to accurately return to its original position within the first connecting hole 7 and the second connecting hole 8. This design avoids the cumbersome manual positioning required in traditional structures, achieving automatic alignment of the connecting shaft 3 during machine head disassembly. Compared to existing technologies, this solution only requires a simple pull of the cable 16 at the handrail to complete machine head disassembly, eliminating the need for tools or close-range operation of connecting components, significantly improving the convenience and reliability of the disassembly operation.

[0040] In this embodiment, a drive shaft 19 is mounted on the body connecting seat 1 via a bearing seat 5. An active clutch pawl 20 is fixed on the drive shaft 19, which is connected to the power output end of the power walking mechanism. A driven clutch pawl 21, which drives the machine head to rotate, is mounted on the head connecting seat 2. The driven clutch pawl 21 engages with the active clutch pawl 20. The ends of the driven clutch pawl 21 and the active clutch pawl 20 respectively form mutually engaging inclined surfaces. These inclined surfaces facilitate easy engagement between the driven clutch pawl 21 and the active clutch pawl 20 during the engagement process. The inclined surface design of the active clutch pawl 20 and the driven clutch pawl 21 can take various forms. For example, the inclination angle of the inclined surface can be between 30 degrees and 60 degrees, preferably 45 degrees, to ensure smooth engagement. The surface of the inclined surface can be polished to reduce frictional resistance. In a preferred embodiment, the active clutch pawl 20 and the driven clutch pawl 21 can be made of high-strength alloy steel to improve wear resistance and service life. Furthermore, the engagement portion of the bevel can be provided with guide grooves to further ensure the accuracy and stability of engagement. In another preferred embodiment, anti-slip textures can be provided on the bevel to increase the coefficient of friction. Furthermore, the engagement surface of the bevel can be hardened to improve wear resistance. Thus, through the guiding effect of the bevel, automatic centering and smooth engagement of the clutch pawls can be achieved during machine head installation.

[0041] The beveled design allows for smoother and more stable engagement between the active clutch pawl 20 and the driven clutch pawl 21, thus solving the problem of jamming or inaccurate alignment during the connection of the clutch head and body in existing technologies. This makes disassembly and installation of the clutch head more convenient, requiring no complex tools or additional adjustments, significantly improving the user experience. Furthermore, the beveled design reduces wear during engagement, extends the service life of the clutch pawls, and lowers the difficulty of aligning them, enabling reliable connection without precise alignment, greatly simplifying the disassembly and assembly of the clutch head. The angle of the bevel ensures sufficient guidance during engagement without generating excessive axial resistance. With this structure, the operator only needs to roughly align the clutch head with the body and push it in to automatically connect the power transmission mechanism, effectively solving the operational difficulties of requiring precise alignment in existing technologies.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
