Description

Technical Field

[0001] This application relates to the field of snow and ice removal technology, and in particular to snow and ice removal devices. Background Technology

[0002] In the cold winter, snow accumulation on roads is a common and significant problem. If snow is not cleared promptly, it significantly reduces road surface friction, thereby greatly increasing the probability of traffic accidents and seriously threatening road safety. Especially in certain special road sections, such as narrow roads or lightly loaded surfaces, large snowplows are difficult to operate due to their bulk and limited maneuverability, and cannot meet the snow removal needs of such road surfaces. Therefore, snow removal work on these special road surfaces currently relies mainly on manual operation or the use of small, mechanically driven snow removal equipment.

[0003] However, manual snow removal is inefficient and increases the workload of workers. While using small snow removal equipment reduces the need for manpower, it struggles to efficiently remove broken ice fragments after ice breaking, resulting in poor convenience and failing to meet the requirements for efficient and convenient snow removal in actual snow removal work. Summary of the Invention

[0004] Based on this, an ice-removing device is provided, which can more easily clean up broken ice blocks on the ground after ice is broken.

[0010] The ice-breaking structure includes an ice-breaking part and an elastic element. A portion of the ice-breaking part can be movably extended out of the accommodating space, and the elastic element is connected to the ice-breaking part.

[0011] When the first shaft is configured to rotate relative to the second support, it drives the eccentric wheel to rotate synchronously, so that the eccentric wheel contacts the ice-breaking part and pushes the ice-breaking part downward; or, the eccentric wheel is made to move away from the ice-breaking part, and the elastic element pushes the ice-breaking part upward.

[0012] In one embodiment, the ice-breaking mechanism includes a synchronization component, which includes a first synchronization belt and two first synchronization pulleys;

[0013] Each of the first synchronous pulleys is connected to a corresponding first shaft, and the two first synchronous pulleys are connected by the first synchronous belt.

[0014] In one embodiment, the ice-breaking section includes a push plate and a plurality of ice-breaking cones, the plurality of ice-breaking cones being disposed on the side of the push plate away from the eccentric wheel, and the plurality of ice-breaking cones being connected to the push plate;

[0015] When the eccentric wheel is rotated, it pushes against the push plate, causing the push plate to drive the ice-breaking cone downwards, so that the tip of the ice-breaking cone can move out of the accommodating space.

[0016] In one embodiment, the push plate is provided with a limiting channel, which is arranged vertically; the second support portion is provided with a limiting portion;

[0017] The limiting part can move within the limiting channel, thereby restricting the movement direction of the push plate and causing the push plate to move in the vertical direction.

[0018] In one embodiment, the ice-breaking mechanism includes a first drive unit configured to drive the first shaft to rotate.

[0019] In one embodiment, the first drive unit is disposed within the accommodating space; wherein, the first drive unit includes a first drive motor, a second synchronous belt, a support base, and two second synchronous pulleys;

[0020] The support base is connected to the second support part, the first drive motor is disposed on the support base, the output end of the first drive motor is connected to one of the second synchronous pulleys, the other second synchronous pulley is sleeved on one of the first shafts, and the two second synchronous pulleys are connected by the second synchronous belt.

[0021] In one embodiment, the cleaning unit includes a rotating shaft and a plurality of cleaning bodies, the plurality of cleaning bodies being arranged along the circumferential outer wall of the rotating shaft, and the two ends of the rotating shaft being rotatably disposed on the first support unit.

[0022] In one embodiment, the cleaning mechanism includes a second drive unit configured to drive the rotating shaft of the cleaning unit to rotate.

[0023] In one embodiment, the second driving part includes a second driving motor, which is disposed on the first support part;

[0024] The cleaning mechanism also includes a transmission assembly, which includes a support shaft, a drive gear, a driven gear, a third synchronous belt, and two third synchronous pulleys.

[0025] The second drive unit is configured to drive the support shaft to rotate, and the support shaft is rotatably disposed on the first support unit;

[0026] One of the third synchronous pulleys and the driving gear are respectively sleeved on the support shaft, and the other third synchronous pulley is sleeved on one of the rotating shafts. The two third synchronous pulleys are connected by the third synchronous belt.

[0027] The driven gear is mounted on another rotating shaft, and the driving gear meshes with the driven gear.

[0028] In one embodiment, the first support includes a support frame, a snow shield, and a plurality of wheels. The snow shield is disposed on the rear side of the support frame, and the plurality of wheels are disposed on the left and right sides of the support frame, respectively.

[0029] The cleaning unit is disposed within the support frame, and the two ends of the rotating shaft of the cleaning unit rotatably pass through the corresponding walking wheel and the support frame in sequence, and are connected to the transmission component.

[0030] The first support includes a protective shell, which covers the transmission assembly and the second drive unit and is connected to the support frame;

[0031] The second support portion is disposed on the front side of the support frame. The support frame is provided with a first snap-fit ​​portion, and the second support portion is provided with a second snap-fit ​​portion. The second support portion is snapped into the first snap-fit ​​portion of the support frame through the second snap-fit ​​portion.

[0032] The aforementioned snow and ice removal device and method utilize the cooperation of an eccentric wheel and an elastic element to achieve the reciprocating motion of the ice-breaking cone. Through the continuous rotation of the first shaft, the eccentric wheel periodically pushes and releases the ice-breaking section, causing it to reciprocate vertically and continuously break up the frozen ice layer. The broken ice blocks are then swept away by a sweeping mechanism as the device moves. The two sweeping sections of the sweeping mechanism rotate in opposite directions, thus throwing the snow to both sides of the device, completing the snow and ice removal operation, preventing snow accumulation in front of the device, and improving snow removal efficiency.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] The related technology includes a road snow removal and ice breaking device comprising a movable platform with a detachable handrail bracket on its left side, on which a control switch is mounted. The right side of the platform features a rapid ice-breaking mechanism for breaking up ice, and a movable snow removal mechanism is also mounted on the platform. The rapid ice-breaking mechanism includes a vertical slide rail fixedly mounted on the right side of the platform, with a rectangular slider movably mounted on the rail. This road snow removal and ice breaking device, through the rapid ice-breaking mechanism and the cooperation between a winding drum and an ice-breaking hammer, can automatically and rapidly break up the ice layer on the snow surface. This design can effectively accelerate the penetration rate of the de-icing agent, thereby greatly improving the efficiency of snow removal. Furthermore, the device also has the function of automatically removing ice debris adhering to the surface of the ice-breaking hammer, eliminating the need for manual removal and reducing the workload of workers.

[0052] However, after the ice-breaking operation is completed, the device has difficulty in efficiently cleaning up the broken ice on the ground, resulting in poor convenience in clearing snow and ice and failing to meet the requirements for efficient and convenient snow and ice removal in actual snow removal work.

[0053] In some exemplary embodiments, such as Figures 1-4 As shown, a snow and ice removal device includes a support structure 1, a sweeping mechanism 2, and an ice-breaking mechanism 3. The support structure 1 serves as the main load-bearing component of the device, housing the sweeping mechanism 2 and the ice-breaking mechanism 3. The sweeping mechanism 2 removes surface snow, while the ice-breaking mechanism 3 breaks up frozen ice. The support structure 1, the sweeping mechanism 2, and the ice-breaking mechanism 3 work together to achieve continuous snow and ice removal functionality that combines ice breaking and sweeping.

[0054] In this embodiment, as Figures 1-4 As shown, the support structure 1 includes a first support part 11 and a second support part 12, which are detachably connected. For example, the first support part 11 is a frame structure, which includes a support frame 111. The support frame 111 includes two parallel longitudinal beams 1111 and a crossbeam 1112 connecting the two longitudinal beams 1111. The crossbeam 1112 is located on the rear side of the support frame 111 and can be integrally formed with the longitudinal beams 1111 to improve the reliability of the connection.

[0055] The second support portion 12 is disposed on the front side of the support frame 111 and is engaged with the longitudinal beam 1111 to achieve a detachable connection. For example, the support frame 111 is provided with a first engaging portion 1113, and the second support portion 12 is provided with a second engaging portion 122. The second support portion 12 is engaged with the first engaging portion 1113 of the support frame 111 through the second engaging portion 122.

[0056] In some feasible embodiments, the first snap-fit ​​portion 1113 is a plug-in groove, which is vertically positioned on the longitudinal beam 1111 but does not penetrate through it. The second snap-fit ​​portion 122 is a plug-in block, which can be embedded or attached to the plug-in groove. To further improve the reliability of the connection between the first support portion 11 and the second support portion 12 and prevent them from loosening, the second snap-fit ​​portion 122 is provided with a first through hole 1221, and the first snap-fit ​​portion 1113 is provided with a first threaded hole 11131. One end of a screw 13 passes through the first through hole 1221 and is screwed into the first threaded hole 11131 to securely install the second support portion 12 onto the first support portion 11.

[0057] In other possible implementations, the first engaging portion 1113 is a T-shaped slider, and the second engaging portion 122 is a groove that matches the T-shaped slider. The groove is formed on the outer wall of the second support portion 12, is vertically oriented, and does not penetrate the second support portion 12, so as to support the T-shaped slider and prevent it from dislodging from the groove. In this case, to further improve the reliability of the connection between the first support portion 11 and the second support portion 12, it can also be fixed using bolts or screws.

[0058] The second support portion 12 is a box structure with an internal accommodating space 121 for accommodating the ice-breaking mechanism 3. For example, the second support portion 12 includes a box body 123 and a top cover 124. The accommodating space 121 is formed in the box body 123 to accommodate a portion of the ice-breaking mechanism 3. The top cover 124 can be fastened to the box body 123 to seal the accommodating space 121 and protect the internal ice-breaking mechanism 3. A second through hole 1231 communicating with the accommodating space 121 is provided on the bottom wall of the box body 123, through which a portion of the ice-breaking mechanism 3 passes.

[0059] In this embodiment, as Figures 1-5 As shown, the sweeping mechanism 2 is used to remove ice blocks scattered after ice breaking and surface snow. The sweeping mechanism 2 includes two sweeping parts 21, which are rotatably mounted on the longitudinal beam 1111 of the first support part 11. The two sweeping parts 21 rotate in opposite directions, thereby throwing the snow to both sides of the device, preventing snow from accumulating in front of the device and improving snow removal efficiency.

[0060] First Example

[0061] The sweeping section 21 is a cylindrical sweeping brush, the main body of which can be a metal or high-strength plastic core shaft, with densely arranged bristles on the outer periphery. The bristles can be made of nylon, which is relatively soft and suitable for light snow or loose snow, avoiding damage to the road surface. Alternatively, the bristles can be made of steel wire, which is suitable for heavy snow, icy snow, or snow containing impurities, improving snow-breaking ability. The sweeping section 21 can be connected to the longitudinal beam 1111 of the first support section 11 via a connecting shaft. Specifically, the longitudinal beam 1111 is provided with a bearing seat, and the connecting shaft cooperates with the bearing in the bearing seat to achieve free rotation of the sweeping section 21.

[0062] Second example

[0063] The sweeping unit 21 includes a rotating shaft 211 and multiple sweeping bodies 212, with a more robust structure suitable for severe snow conditions. The rotating shaft 211 is, for example, a cylindrical rod made of metal, which is rotatably mounted on the longitudinal beam 1111 at both ends via bearing seats to ensure smooth rotation.

[0064] The sweeping body 212 has a "rake tooth" structure and is made of high-strength plastic or stainless steel. Multiple sweeping bodies 212 are arranged along the outer circumferential wall of the rotating shaft 211, such as being evenly distributed along the axial direction of the rotating shaft 211 or spirally distributed along the circumference, to break up ice and snow blocks and throw the snow to both sides.

[0065] To achieve automated snow removal and reduce manpower consumption, the sweeping mechanism 2 may further include a second drive unit 22, which is configured to drive the rotating shaft 211 of the sweeping unit 21 to rotate. For example, the second drive unit 22 includes a second drive motor, which is disposed on the first support unit 11.

[0066] The housing of the second drive motor is bolted to the side of the longitudinal beam 1111 away from the cleaning section 21 to prevent snow accumulation and blockage. The drive shaft of the second drive motor is connected to the rotating shaft 211 via a coupling. There can be two second drive motors, suitable for scenarios requiring high torque. Each second drive motor corresponds to one rotating shaft 211. By controlling the rotation direction of the two second drive motors, such as the rear motor rotating clockwise and the front motor rotating counterclockwise, the two cleaning sections 21 can be rotated in opposite directions.

[0067] Alternatively, the number of second drive motors can be set to one, which is suitable for compact structural requirements. To simplify the structure and reduce costs, the second drive unit 22 can use a single second drive motor, which works in conjunction with the transmission assembly 23 to achieve synchronous reverse rotation of the two rotating shafts 211. The cleaning mechanism 2 includes the transmission assembly 23, which includes a support shaft 231, a drive gear 232, a driven gear 233, a third synchronous belt 234, and two third synchronous pulleys 235.

[0068] The housing of the second drive unit 22 is fixedly connected to the longitudinal beam 1111 of the first support unit 11. The drive shaft of the second drive unit 22 is fixedly connected to the support shaft rod 231 so as to drive the support shaft rod 231 to rotate. The support shaft rod 231 is located on the side of the first support unit 11 away from the cleaning unit 21 and is rotatably connected to the longitudinal beam 1111 of the first support unit 11.

[0069] The end of the rotating shaft 211 can rotatably pass through the corresponding longitudinal beam 1111. One of the third synchronous pulleys 235 is located on the side of the longitudinal beam 1111 away from the cleaning part 21 and is fixedly sleeved on the support shaft 231. The other third synchronous pulley 235 is located on the side of the longitudinal beam 1111 away from the cleaning part 21 and is fixedly sleeved on one of the rotating shafts 211. The two third synchronous pulleys 235 are connected by a third synchronous belt 234.

[0070] The driving gear 232 is fixedly sleeved on the support shaft 231 and coaxially arranged with one of the third synchronous pulleys 235 to achieve synchronous rotation between the third synchronous pulley 235 and the driving gear 232. The driven gear 233 is sleeved on another rotating shaft 211, and the driving gear 232 and the driven gear 233 are meshed together.

[0071] The second drive unit 22 drives the support shaft 231 to rotate. The support shaft 231 drives one of the third synchronous pulleys 235 and the drive gear 232 to rotate synchronously. When the support shaft 231 rotates counterclockwise, one of the third synchronous pulleys 235 and the drive gear 232 rotate synchronously counterclockwise, while the driven gear 233 meshing with the drive gear 232 rotates clockwise. The driven gear 233 drives another rotating shaft 211 to rotate clockwise, while the other third synchronous pulley 235 connected by the third synchronous belt 234 rotates counterclockwise. This achieves synchronous counterclockwise rotation of the two sweeping units 21. The counterclockwise rotation of the two sweeping units 21 can throw snow to both sides of the device, preventing snow from accumulating in front of the device.

[0072] Meanwhile, to protect the transmission assembly 23 and the second drive unit 22 from snow and debris blockage, and to improve operational safety, the first support unit 11 includes a protective shell 112. The protective shell 112 covers the outside of the transmission assembly 23 and the second drive unit 22 and is connected to the support frame 111. For example, the protective shell 112 includes a first sub-shell 1121 and a second sub-shell 1122. The first sub-shell 1121 covers the transmission assembly 23, and is detachably connected to the longitudinal beam 1111 of the first support unit 11 by bolts or snap-fit, facilitating future maintenance. The second sub-shell 1122 covers the second drive unit 22, and is detachably connected to the first sub-shell 1121 by bolts or snap-fit, facilitating future maintenance. The first sub-shell 1121 has a through hole with a diameter slightly larger than the diameter of the support shaft 231, allowing the drive shaft of the second drive motor to pass through and be fixedly connected to the support shaft 231 to ensure smooth transmission.

[0073] In this embodiment, the sweeping mechanism 2, through the design of the reverse rotation and flexible drive of the dual sweeping parts 21, solves the problems of snow accumulation, poor adaptability and low degree of automation in the sweeping device in related technologies. It works in conjunction with the ice-breaking mechanism 3 to achieve continuous ice-breaking and sweeping operations, significantly improving the efficiency of snow and ice removal.

[0074] In this embodiment, as Figures 1-8 As shown, the ice-breaking mechanism 3 is disposed within the accommodating space 121. The ice-breaking mechanism 3 includes a pushing part 31 and an ice-breaking structure 32.

[0075] The pushing part 31 includes a first shaft 311 and a plurality of eccentric wheels 312. The first shaft 311 is arranged in a horizontal direction, and its two ends are rotatably mounted on the inner sidewall of the second support part 12 through bearings (not shown in the figure), ensuring that the first shaft 311 can rotate flexibly. The plurality of eccentric wheels 312 are sleeved at equal intervals along the axial direction of the first shaft 311 and are fixed to the first shaft 311 by key connection, ensuring that the rotation of the first shaft 311 drives the eccentric wheels 312 to rotate synchronously.

[0076] The number of eccentric wheels 312 is designed according to the length of the accommodating space 121. For example, there are five eccentric wheels 312 (which can be increased according to actual needs). The spacing between adjacent eccentric wheels 312 is 10-15cm to achieve uniform pushing against the ice-breaking part 321. The eccentricity of the eccentric wheel 312 is, for example, but not limited to, 5-10mm, that is, the distance between the center of the eccentric wheel 312 and the axis of the first shaft 311 is 5-10mm. This makes a height difference between the outer edge of the eccentric wheel 312 and the contact position with the ice-breaking part 321 when the eccentric wheel 312 rotates, thereby achieving pushing or releasing against the ice-breaking part 321.

[0077] The ice-breaking structure 32 includes an ice-breaking part 321 and an elastic element 322. The ice-breaking part 321 includes, for example, a push plate 3211 and a plurality of ice-breaking cones 3212. The plurality of ice-breaking cones 3212 are fixedly disposed on the side of the push plate 3211 away from the eccentric wheel 312. The push plate 3211 is used to contact the eccentric wheel 312.

[0078] The icebreaker 3212 is a columnar structure made of high-strength alloy steel, ensuring its structural strength is sufficient to break the ice. The icebreaker 3212 has a pointed side and a flat end side. The flat end side is fixedly connected to the push plate 3211. The pointed side of the icebreaker 3212 movably protrudes from the receiving space 121 through the second through hole 1231 in the bottom wall of the second support part 12 for insertion and breaking the ice.

[0079] The elastic element 322 is a spring, the number of which is the same as that of the icebreaker 3212, and it is sleeved on the radial outer side of the icebreaker 3212. The upper end of the spring is connected to the push plate 3211, and the lower end of the spring is connected to the inner bottom wall of the second support part 12. The elastic element 322 is initially in a slightly compressed state, providing an upward elastic force, so that the tip side of the icebreaker 3212 is partially retracted into the receiving space 121 when no external force is applied.

[0080] The ice-breaking cone 3212 movably passes through the second through hole 1231 of the second support part 12 in a vertical direction. The ice-breaking cone 3212 slides against the inner wall of the second through hole 1231 to ensure that the ice-breaking part 321 moves only vertically and avoids deviation. To limit the movement direction of the ice-breaking part 321 and prevent deviation, a limit channel 32111 is provided vertically through the push plate 3211. A limit part 125 is fixedly provided on the inner side wall of the second support part 12. The limit part 125 may be a limit block or a limit plate. The limit part 125 can slide within the limit channel 32111, thereby limiting the push plate 3211 to move only vertically and ensuring that the ice-breaking cone 3212 moves smoothly.

[0081] To improve the ice-breaking effect, in this embodiment, the ice-breaking mechanism 3 is equipped with two sets of ice-breaking structures 32, and the synchronous movement of the two sets of ice-breaking structures 32 is achieved through a synchronization component 33. The synchronization component 33 includes a first synchronization belt 331 and two first synchronization pulleys 332. Each first synchronization pulley 332 is connected to a first shaft 311 and is fixedly sleeved on the first shaft 311. The two first synchronization pulleys 332 are connected by the first synchronization belt 331 to achieve synchronous rotation of the two first shafts 311.

[0082] Furthermore, the eccentric wheels 312 in the two sets of ice-breaking structures 32 are arranged opposite each other, and their eccentric positions are different. When the first shaft 311 rotates, the eccentric wheels 312 periodically push against the push plate 3211. Due to the difference in eccentric position, the push plates 3211 of the two sets of ice-breaking structures 32 will move downwards in an alternating manner, thereby generating an alternating striking force on the ice layer and improving the ice-breaking efficiency.

[0083] To reduce manual operation and improve ice-breaking efficiency, the ice-breaking mechanism 3 includes a first drive unit 34, which is configured to drive the first shaft 311 to rotate.

[0085] The first drive unit 34 includes a first drive motor. The housing of the first drive motor is fixedly connected to the second support unit 12. The drive shaft of the first drive motor rotatably passes through the side wall of the second support unit 12 and extends into the accommodating space 121, and is fixedly connected to one of the first shafts 311. Through the transmission of the synchronization component 33, one drive motor can simultaneously drive two first shafts 311 to rotate synchronously.

[0086] Second example

[0087] The first drive unit 34 includes two first drive motors. The housings of the first drive motors are fixedly connected to the second support unit 12. The drive shafts of the first drive motors rotatably pass through the side wall of the second support unit 12 and extend into the accommodating space 121. The drive shafts of the two first drive motors are respectively connected to the first shafts 311. The two shafts are started or stopped synchronously by the control system to ensure the synchronicity of the movement of the two first shafts 311. This arrangement does not require an additional synchronization component 33, and the layout logic is simple.

[0088] Third Example

[0089] The first drive unit 34 includes a first drive motor and is located within the accommodating space 121, thereby protecting the first drive motor from exposure and effectively improving the safety factor of the ice-breaking mechanism 3. The first drive unit 34 includes a first drive motor 341, a second synchronous belt 342, a support base 343, and two second synchronous pulleys 344.

[0090] The support base 343 is fixedly connected to the second support part 12. The housing of the first drive motor 341 is fixedly mounted on the support base 343. The output end of the first drive motor 341 is fixedly connected to one of the second synchronous pulleys 344. The other second synchronous pulley 344 is sleeved on one of the first shafts 311. The two second synchronous pulleys 344 are connected by a second synchronous belt 342. This arrangement places the first drive motor 341 within the accommodating space 121, which can effectively protect the first drive part 34 and extend its service life.

[0091] When the de-icing device needs to break the frozen ice layer, the first drive motor 341 drives the first shaft 311 to rotate, and the first shaft 311 drives the eccentric wheel 312 to rotate synchronously.

[0092] When the major axis of the eccentric wheel 312 (such as the distance from the outermost part of the eccentric wheel 312 to the axis of the first shaft 311) rotates to contact the push plate 3211, the eccentric wheel 312 pushes the push plate 3211 downwards. The push plate 3211 drives the ice-breaking cone 3212 to move downwards. The tip of the ice-breaking cone 3212 penetrates the receiving space 121 and inserts into the ice layer, applying downward pressure to the ice layer to break it. At this time, the elastic element 322 is compressed and accumulates elastic potential energy.

[0093] When the short diameter of the eccentric wheel 312 (such as the distance from the innermost side of the eccentric wheel 312 to the axis of the first shaft 311) rotates to contact the push plate 3211, the eccentric wheel 312 separates from the push plate 3211, and the elastic element 322 pushes the push plate 3211 upward due to the elastic restoring force, which drives the ice-breaking cone 3212 to reset upward, and the tip side is at least partially retracted into the accommodating space 121.

[0094] Through the continuous rotation of the first shaft 311, the eccentric wheel 312 periodically pushes and releases the ice-breaking part 321, causing the ice-breaking part 321 to reciprocate in the vertical direction, thereby continuously breaking the frozen ice layer. The broken ice blocks are swept to both sides of the device by the sweeping part 21 of the sweeping mechanism 2 as the device moves, completing the de-icing and snow removal operation.

[0095] In this embodiment, the reciprocating motion of the ice-breaking cone 3212 is achieved through the cooperation of the eccentric wheel 312 and the elastic element 322. Combined with the setting of the synchronization component 33 and the first drive unit 34, the ice-breaking action is ensured to be continuous, efficient and stable, and the ice layer breaking effect is effectively improved.

[0096] In this embodiment, as Figures 1-4 As shown, a snow and ice removal device for vehicles is provided, the structure of which is designed to improve the efficiency of snow and ice removal and the stability of the device movement.

[0097] The structural configuration of the first support part 11 has been described in detail above and will not be repeated here. The difference is that the first support part 11 also includes a snow shield 114 and multiple wheels 113.

[0098] The snow deflector 114 is fixedly installed on the rear side of the support frame 111 and is located on the side of the crossbeam 1112 of the support frame 111 near the sweeping section 21. The snow deflector 114 is designed to facilitate the pushing of ice and snow, thereby preventing the accumulation of ice and snow in front of the vehicle and avoiding the impact of ice and snow on the normal operation of the vehicle. For example, the snow deflector 114 may include a first plate 1141, a transition section 1142, and a second plate 1143.

[0099] The first plate 1141 is a rectangular plate extending vertically, with its lower end spaced 10-20mm from the ground to avoid friction. Its upper end is bolted to the front side of the crossbeam 1112, with bolt holes spaced along the length of the first plate 1141 to enhance connection strength. The width of the first plate 1141 is matched to the length of the crossbeam 1112 to completely block ice and snow in front.

[0100] The transition section 1142 is an arc-shaped structure connecting the lower end of the first plate 1141 and the second plate 1143, with a radius of curvature of 50-80mm, curving towards the inner side of the support frame 111 (i.e., the area between the two longitudinal beams). The design of this transition section 1142 can prevent ice and snow from accumulating at the corner between the first plate 1141 and the second plate 1143, allowing ice and snow to smoothly transition from the vertical direction to the horizontal direction.

[0101] The second plate 1143 is a rectangular plate extending horizontally, welded and fixed to the end of the transition section 1142. Its end can extend inward toward the inside of the support frame 111 to above the sweeping section 21, at a distance of 30-50mm from the sweeping section 21. The second plate 1143 further blocks ice and snow, and in conjunction with the sweeping section 21, it can guide ice and snow to the sweeping section 21, preventing ice and snow from leaking from the gap between the snow baffle 114 and the sweeping section 21.

[0102] The traveling wheels 113 are used to support the entire snow removal device and drive the device to move synchronously when the vehicle is moving. There are four traveling wheels 113, which correspond to the front left, rear left, front right, and rear right positions of the support frame 111, that is, the front and rear ends of the left longitudinal beam 1111 and the front and rear ends of the right longitudinal beam 1111.

[0103] Mounting holes 11111 are provided at intervals along the length of the longitudinal beams 1111 on the left and right sides of the support frame 111, and rolling bearings are embedded in the mounting holes 11111.

[0104] The rotating shaft 211 is arranged along the width direction (lateral direction) of the vehicle, and its two ends pass through the mounting holes 11111 of the corresponding wheel axle sleeves of the traveling wheel 113 and the support frame 111, respectively, and are connected to the transmission assembly 23. The wheel axle sleeves and the rotating shaft 211 are connected by a key to achieve circumferential fixation, ensuring that the traveling wheel 113 and the rotating shaft 211 rotate synchronously.

[0105] An oil seal (made of nitrile rubber) is provided between the shaft 211 and the mounting hole 11111 of the support frame 111 to prevent dust and snow water from entering the bearing and extend the service life of the traveling wheel 113.

[0106] As the vehicle moves forward, the travel wheels 113 rotate with the vehicle. Simultaneously, the rubber material of the travel wheels 113 increases friction with the ground, preventing the device from slipping on icy or snowy surfaces.

[0107] To facilitate quick connection between the snow and ice removal device and the vehicle, multiple connecting ears 11121 are fixedly installed on the rear side of the crossbeam 1112, i.e., the side opposite to the sweeping section 21. These connecting ears 11121 are spaced apart along the length of the crossbeam 1112. The connecting ears 11121 are made of metal plate with a thickness of 8mm. One end of each connecting ear 11121 is welded to the crossbeam 1112 with a weld length of 50mm to ensure connection strength. The other end has a Φ12mm bolt hole.

[0108] During installation, align the tow bar (not shown in the figure) at the front of the vehicle with the connecting lug 11121, and fix the support frame 111 to the tow bar by passing bolts through the bolt holes. This connection method is simple to operate and allows for quick assembly and disassembly of the device from the vehicle. It is suitable for de-icing and snow removal operations in large areas such as squares, parking lots, and airport runways.

[0109] This embodiment solves the problems of easy accumulation and unstable movement of snow and ice when snow and ice are pushed by snow and ice devices in related technologies through the segmented structure of snow baffle 114 and the stable support design of walking wheels 113, and is suitable for efficient snow and ice removal operations in large areas.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
