Description

Technical Field

[0001] This invention relates to the field of ice breaking and snow removal technology, specifically to an integrated ice breaking and snow removal equipment and method. Background Technology

[0002] In the cold winter, heavy snow and ice have a significant impact on vehicle driving, braking, and handling stability, which can easily lead to traffic accidents such as rear-end collisions and skidding, seriously threatening road safety and the safety of people's lives and property.

[0003] Large vans frequently travel between highways, logistics parks, and open-air freight yards. Due to limitations in garage height and site conditions, most vehicles can only be parked outdoors at night and during non-operational hours. After heavy snowfall, the top of the van often accumulates several tens of centimeters of snow. If the low temperatures persist or the vehicle experiences freeze-thaw cycles, a dense layer of ice, several centimeters thick, forms between the bottom layer of snow and the metal surface of the van top. This snow and ice not only significantly increases the vehicle's weight, leading to increased fuel consumption and reduced power performance, but also, when the vehicle is traveling at high speeds, can break off in chunks due to vibration or wind, hitting following vehicles or scattering on the road, easily causing serious secondary accidents such as emergency swerving or broken windshields.

[0004] Currently, the market for removing snow and ice from the roofs of large vans relies on either manual climbing or snowplows. Traditional manual climbing methods are extremely inefficient and pose a risk of falls from heights, while ordinary snowplows can only remove loose snow and cannot handle ice, failing to meet the requirements for fast, safe, and thorough operations. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated snow removal equipment and method for breaking ice and removing snow, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated snow removal and ice breaking equipment and method, comprising a van and a snow removal mechanism, wherein the snow removal mechanism includes a snow removal frame that allows the van to pass through, a pair of first hydraulic push rods symmetrically mounted on the top of the snow removal frame, a lifting frame slidably mounted on the upper part of the snow removal frame, and the output end of the first hydraulic push rods rotatably mounted on the top of the lifting frame, an installation frame fixedly mounted on the side of the lifting frame, an adjustment frame rotatably mounted on the installation frame, a snow shovel rotatably mounted on the adjustment frame, a rubber strip fixed at the bottom of the snow shovel, and an ice crushing mechanism, wherein the ice crushing mechanism includes a plurality of side plates disposed at the bottom of the adjustment frame, a plurality of sleeve frames circumferentially disposed between the two adjacent and farthest side plates, connecting rings symmetrically fixed at both ends of the sleeve frames, the sleeve frames and the connecting rings being rotatably connected to the side plates, and ice crushing teeth slidably mounted inside the sleeve frames; The side plate is provided with a pressure relief assembly for controlling the sliding of the ice crushing tooth. The pressure relief assembly includes a pressure plate fixed on the side plate near the sleeve frame. A pressure relief plate is also movably installed on the side plate near the sleeve frame. Roller columns are symmetrically fixed at both ends on the side of the ice crushing tooth near the axis, and the roller columns are respectively located at the pressure plate and the pressure relief plate.

[0007] Preferably, a crossbeam is fixedly installed on the bottom surface of the adjusting frame, and several boosters are equidistantly installed on the bottom of the crossbeam. The side plate is fixed on the side of the booster output end, wherein the two adjacent and closest side plates are fixed on both sides of the corresponding booster output end. A rotating shaft is also rotatably installed on the booster output end, the rotating shaft passing through the side plate. Several sets of support frames are fixed circumferentially on the rotating shaft, wherein four sleeve frames are fixed on the support frames. Several spring sleeves are equidistantly fixed on the side of the sleeve frames near the rotating shaft, and a first spring is installed inside the spring sleeve, the end of the first spring abutting against the corresponding ice-crushing tooth.

[0008] Preferably, a plurality of second hydraulic push rods are equidistantly installed on the side of the crossbeam, and a connecting arm is fixed to the output end of the second hydraulic push rod. An adjustment groove is provided on the side plate, and a slider is slidably installed inside the adjustment groove. The two ends of the slider are respectively fixedly installed at the bottom end of the connecting arm and the side of the pressure relief plate.

[0009] Preferably, a buffer assembly is provided on the side of the sleeve frame away from the pivot to reduce the pressure exerted by the sleeve frame on the roof, thereby protecting the roof of the van. The buffer assembly includes a wing plate that rotates symmetrically around the outer end of the sleeve frame. A first torsion spring is installed at the point where the wing plate rotates with the sleeve frame. A flap is rotatably installed on the outer surface of the wing plate. A second torsion spring is installed at the point where the flap is rotated with the wing plate. Pads are fixed at equal intervals on the inner side of the flap. A rubber pad is connected to the side of the flap and the edge of the wing plate.

[0010] Preferably, the sleeve frame is provided with a control component for controlling the movement of the wing plate. The control component includes an arc-shaped groove formed inside the side plate. An inner sleeve frame is slidably installed inside the sleeve frame. Several sleeves are fixed at equal intervals on both sides of the inner sleeve frame. The sleeves abut against the inner surface of the wing plate. First racks are symmetrically fixed at both ends of the inner sleeve frame. Gears are rotatably installed inside both ends of the sleeve frame. Second racks are slidably installed inside both ends of the sleeve frame. The corresponding first racks and second racks are meshed with the gears. A linkage block is slidably installed inside the end of the second rack. The linkage block passes through the end of the sleeve frame, and one end of the linkage block abuts against the inner side of the ice-crushing tooth. The linkage block is elastically connected to the second rack through a second spring. A pulley is installed at the other end of the linkage block. The pulley abuts against the inner side of the side plate and the arc-shaped groove.

[0011] Preferably, each set of support frames is provided with a vibration assembly for driving the wing plate to shake off accumulated ice. The vibration assembly includes a corrugated arc plate fixed on each set of support frames. A top rod is slidably disposed inside the sleeve. The top rod passes through the sleeve frame, and one end of the top rod abuts against a pad inside the wing plate, while the other end of the top rod abuts against the corrugated arc plate. A third spring is installed on the top rod.

[0012] Preferably, the bottom of the mounting frame is equipped with a de-icing assembly for scraping and guiding ice fragments away from the vehicle roof. The de-icing assembly includes a deflector plate movably mounted on the bottom of the mounting frame, and a scraper plate is fixedly mounted on the bottom of the deflector plate.

[0013] Preferably, a snow removal method using an integrated ice-breaking and snow-removing snow removal equipment includes the following steps: S1: The first hydraulic push rod drives the lifting frame to the highest point, and the van drives into the appropriate position under the snowplow. The first hydraulic push rod drives the lifting frame to descend, so that the rubber strip and shovel plate abut against the roof of the van. S2: Synchronously control the adjustment frame and de-icing components to tilt the snowplow, ice crushing mechanism and de-icing components at a certain angle relative to the van. Then adjust the length of the supercharger so that the ice crushing teeth press against the ice layer with a certain pressure. After it is in place, the van moves forward slowly. The snowplow and rubber strips first scrape off the snow on the roof of the vehicle, exposing the ice layer. S3: The "roller" formed by the frame and the ice-crushing teeth rotates using the friction of the van. Whenever the ice-crushing teeth rotate to get close to the ice layer, the roller column hits the pressure plate, preventing the ice-crushing teeth from sliding. The ice-crushing teeth are rigidly connected to the frame, thereby generating enough pressure to break the ice layer. S4: When the ice-crushing tooth reaches the bottom of the "roller", the roller column slides to the bottom of the pressure relief plate. If the pressure of the ice-crushing tooth exceeds the threshold, the second hydraulic push rod drives the connecting arm to retract upward, the pressure relief plate releases the roller column, and the ice-crushing tooth slides into the inner sleeve frame to reduce the pressure of the ice-crushing tooth on the roof and protect the roof. When sliding, the wing plate removes ice fragments from the surface of the ice-crushing tooth. S5: When the ice-breaking tooth slides, it drives the inner sleeve frame to slide, causing the sleeve to lift the wing plate. The rubber pad on the outer surface of the wing plate abuts against the roof surface, further reducing the impact. S6: When the ice-crushing tooth rotates to the arc groove, the linkage block retracts, the arc groove and sleeve reset, the wing plate resets, and at the same time the push rod abuts against the corrugated arc plate, forming a reciprocating sliding motion. By impacting the pad block, it drives the flap to fan, stretching the rubber pad, and using vibration to remove the ice attached to the outer surface of the wing plate. S7: The "roller" rotates in a cycle to break up the ice on the roof. The deflector and scraper are behind the "roller" to scrape off the ice fragments.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By installing a snow removal mechanism, ice crushing mechanism, and de-icing components on the snowplow frame that can be raised and lowered according to the height of the van, the snowplow removes the snow accumulated on the top of the van as the van moves slowly forward, exposing the ice layer. The "roller" formed by the frame rotates, causing the ice crushing teeth to crush the ice layer one by one, achieving the effect of breaking the ice layer. Moreover, by setting a fixed pressure plate and a pressure relief plate that can move up and down on the inside of the side plate, the ice crushing teeth can be controlled to slide out and retract. During the ice crushing, the pressure plate presses the roller column, causing the ice crushing teeth to slide out from the frame, thereby generating sufficient pressure to crush the ice layer. When the pressure of the ice crushing teeth on the top of the van exceeds the pressure threshold, the second hydraulic push rod drives the pressure relief plate to rise, reducing the pressure of the pressure relief plate on the roller column and controlling the retraction of the ice crushing teeth, thereby reducing the local pressure of the ice crushing teeth on the top of the van, and thus protecting the integrity of the top of the van and its paint.

[0015] 2. Symmetrical wing plates are installed on the outer side of the frame. The symmetrical wing plates have a V-shaped structure. During the process of the ice-crushing teeth retracting into the frame, the wing plates can remove the ice fragments on the surface of the ice-crushing teeth, preventing the ice fragments from freezing on the surface of the ice-crushing teeth. An adjustment component is installed inside the support frame. After the ice-crushing teeth slide into the frame, they start to drive the second rack to slide. Through the transmission and cooperation of the rack and gear, the inner frame drives the sleeve to slide and abut against the wing plates. The wing plates unfold to a horizontal state, replacing the ice-crushing teeth to abut against the top surface of the van. By increasing the contact area, the contact pressure is reduced, thereby reducing the damage to the top of the van caused by excessive local pressure. In addition, the outer side of the rubber pad is covered with a soft rubber pad, which can form a flexible contact and provide cushioning, further reducing the risk of damage to the top surface of the van.

[0016] 3. As the frame continues to roll, when the pulley enters the arc groove, it releases the drive of the ice-crushing teeth to the control component, causing the control component to reset, thereby achieving the effect of wing plate reset. After the wing plate is reset, the top rod begins to abut against the corrugated arc plate, thereby cyclically impacting the pad block, causing the flap to continuously fan, which in turn drives the rubber pad to continuously tighten and loosen, forming elastic deformation, removing the ice fragments attached to the surface of the rubber pad, and avoiding the problem of ice fragments freezing on the surface of the rubber pad.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-12 The present invention provides a technical solution: an integrated snow removal and ice breaking equipment; Example 1: Please refer to Figures 1 to 7 This embodiment describes one feasible structure of an integrated snow removal and ice-breaking equipment. The system includes a van 1 and a snow removal mechanism 2. The snow removal mechanism 2 includes a snow removal frame 20 that allows the van 1 to pass through. A pair of first hydraulic push rods 21 are symmetrically installed on the top of the snow removal frame 20. A lifting frame 22 is slidably installed on the upper part of the snow removal frame 20, and the output end of the first hydraulic push rods 21 is rotatably installed on the top of the lifting frame 22. A mounting frame 23 is fixedly installed on the side of the lifting frame 22. An adjusting frame 24 is rotatably installed on the mounting frame 23. A snowplow 25 is rotatably installed on the adjusting frame 24. A rubber strip 26 is fixed to the bottom of the snowplow 25. In this embodiment, the adjusting frame 24 can be adjusted to swing left and right on the mounting frame 23. The angle adjustment is achieved by a hydraulic rod installed on the mounting frame 23. The output end of the hydraulic rod is rotatably installed on both sides of the adjusting frame 24. The rubber strip 26 is made of soft rubber, which ensures that the snowplow 25 makes flexible contact with the roof of the van 1. Moreover, during the snowplow 25's snow removal process, the rubber strip 26 can fit well against the surface of the ice layer, reducing gaps and ensuring better snow removal effect.

[0021] Ice-crushing mechanism 3 includes several side plates 32 disposed at the bottom of adjusting frame 24. Several sleeve frames 35 are circumferentially arranged between the two adjacent and farthest side plates 32. Connecting rings 36 are symmetrically fixed at both ends of the sleeve frames 35. The sleeve frames 35 and the connecting rings 36 are rotatably connected to the side plates 32. Ice-crushing teeth 39 are slidably installed inside the sleeve frames 35. A crossbeam 30 is fixedly installed on the bottom surface of adjusting frame 24. Several boosters 31 are equidistantly installed at the bottom of the crossbeam 30. The side plates 32 are fixed to the output of the boosters 31. On the side of the end, the two adjacent and closest side discs 32 are fixed on both sides of the corresponding output end of the booster 31. The output end of the booster 31 is also rotatably mounted with a rotating shaft 33, which passes through the side discs 32. Several sets of support frames 34 are fixed around the circumference of the rotating shaft 33. Four sleeve frames 35 are fixed on the support frames 34. Several spring sleeves 37 are fixed at equal intervals on the side of the sleeve frame 35 near the rotating shaft 33. A first spring 38 is installed inside the spring sleeve 37. The end of the first spring 38 abuts against the corresponding ice crushing tooth 39. In this embodiment, the crossbeam 30 is fixedly installed at the bottom of the adjusting frame 24. While the adjusting frame 24 adjusts its angle, the crossbeam 30 and the snowplow 25 change direction synchronously, so that the ice-breaking mechanism 3 and the snowplow 25 are at the same angle. Multiple circumferentially arranged sleeves 35 form a "roller", with both ends fixed on the connecting ring 36. The sleeves 35 are connected to the rotating shaft 33 through the cross-mounted support frame 34. The ice-breaking teeth 39, which are slidably installed inside the sleeves 35, directly contact the ice layer on the roof. When the van 1 moves forward, the frictional resistance causes the "roller" to rotate, and the ice-breaking teeth 39 crush the ice surface with concentrated pressure, thereby playing an ice-breaking role. The "roller" is elastically connected to the crossbeam 30 through the booster 31 and the side plate 32. The booster 31 provides the basic pressure, so that the "roller" contacts the ice surface with a certain pressure, thereby achieving the ice-breaking effect.

[0022] The side plate 32 is provided with a pressure relief assembly 4 for controlling the sliding of the ice crushing tooth 39. The pressure relief assembly 4 includes a pressure plate 42 fixed on the side plate 32 near the sleeve frame 35. A pressure relief plate 45 is also movably installed on the side plate 32 near the sleeve frame 35. Roller columns 46 are symmetrically fixed at both ends on the side of the ice crushing tooth 39 near the axis, and the roller columns 46 correspond to the pressure plate 42 and the pressure relief plate 45 respectively. Several second hydraulic push rods 40 are equidistantly installed on the side of the crossbeam 30. A connecting arm 41 is fixed at the output end of the second hydraulic push rod 40. An adjustment groove 43 is opened on the side plate 32. A slider 44 is slidably installed inside the adjustment groove 43. The two ends of the slider 44 are fixedly installed at the bottom end of the connecting arm 41 and the side of the pressure relief plate 45 respectively. In this embodiment, the effective ice-breaking range of the ice-crushing tooth 39 is during the period when the roller column 46 contacts the pressure plate 42. During this process, the roller column 46 is squeezed by the pressure plate 42, causing the ice-crushing tooth 39 to slide out of the sleeve frame 35. Furthermore, the ice-crushing tooth 39 does not retract when crushing the ice layer. Importantly, when the ice-crushing tooth 39 rotates to the bottom of the "roller," that is, when the ice-crushing tooth 39 is perpendicular to the roof of the van 1, the pressure exerted by the ice-crushing tooth 39 on the van 1 is at its maximum. At this point, the ice-crushing tooth 39 just penetrates the ice layer, and the roller column 46 begins to contact the bottom surface of the pressure relief plate 45. A pilot is provided inside the second hydraulic push rod 40. The pilot-operated relief valve can preset a pressure threshold. Once the ice-crushing tooth 39 is subjected to a reaction force from the top of the van 1 that exceeds the pressure threshold, the pilot-operated relief valve opens to release pressure. The second hydraulic push rod 40 drives the connecting arm 41 to move upward, thereby driving the pressure relief plate 45 to rise through the slider 44. The pressure of the pressure relief plate 45 on the roller column 46 is reduced sharply. Under the elastic force of the first spring 38, the ice-crushing tooth 39 immediately retracts into the sleeve frame 35, eliminating the pressure on the top of the van 1, thus protecting the integrity of the top of the van 1 and its paint surface, and avoiding the problem of excessive pressure on the ice-crushing tooth 39 damaging the roof.

[0023] The bottom of the mounting bracket 23 is equipped with a de-icing assembly 8 for scraping and guiding ice fragments away from the roof. The de-icing assembly 8 includes a deflector plate 80 that is movably mounted on the bottom of the mounting bracket 23, and a scraper plate 81 is fixedly mounted on the bottom of the deflector plate 80. In this embodiment, after the ice-crushing tooth 39 breaks the ice layer, the guide plate 80 and the shovel plate 81 scoop up the ice fragments. The guide plate 80 guides the ice fragments to one side of the van 1 for discharge. The shovel plate 81 is made of a material with an inner metal and an outer rubber coating, which makes flexible contact with the van 1 while ensuring sufficient hardness to scoop up the ice fragments.

[0024] Example 2: Please refer to Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11Based on Embodiment 1, this embodiment takes into account that when the pressure of the ice-breaking tooth 39 on the roof of the van 1 is too great in Embodiment 1, it can retract into the sleeve 35. However, the sleeve 35 will then directly contact the roof of the van 1, and the pressure will continue to be transmitted. In fact, it cannot effectively protect the roof of the van 1. Moreover, during the process of the ice-breaking tooth 39 circulating deep into the ice layer, ice fragments will adhere to the surface of the ice-breaking tooth 39. In addition, due to the cold weather, over time, the ice fragments will condense and firmly adhere to the surface of the ice-breaking tooth 39, thereby increasing the volume of the ice-breaking tooth 39. This not only increases the weight of the ice-breaking tooth 39, causing it to fail to slide, but also leads to a serious reduction in the ice-breaking effect of the ice-breaking tooth 39. Therefore, Embodiment 2 solves the problems of reducing the pressure of the "roller" on the roof of the van 1, the poor roof protection effect, and the removal of ice accumulation on the surface of the ice-breaking tooth 39 through the following structure. A buffer assembly 5 is provided on the side of the frame 35 away from the pivot 33 to reduce the pressure exerted by the frame 35 on the roof, thereby protecting the roof of the van 1. The buffer assembly 5 includes a wing plate 50 that rotates symmetrically at the outer end of the frame 35. A first torsion spring 51 is installed at the point where the wing plate 50 rotates with the frame 35. In this embodiment, the elastic force of the first spring 38 inside the spring sleeve 37 causes the ice-breaking teeth 39 to slide towards the rotating shaft 33. That is, after the ice-breaking teeth 39 no longer press against the pressure plate 42 or the pressure relief plate 45, the roller column 46 is no longer restricted. Under the action of the elastic force of the first spring 38, the ice-breaking teeth 39 retract into the sleeve frame 35. The ice-breaking teeth 39 move relative to the wing plates 50. During this process, the wing plates 50 that abut against both sides of the ice-breaking teeth 39 can scrape off the attached ice fragments, thereby removing the ice fragments in time and preventing the ice fragments from freezing. This keeps the surface of each ice-breaking tooth 39 clean, ensuring an effective ice-breaking effect. The elastic force of the first torsion spring 51 ensures that when no external force is applied, the wing plates 50 can stably fit against the outside of the sleeve frame 35, forming a V-shaped angle between the wing plates 50 and the ice-breaking teeth 39, improving the ice-scraping effect.

[0025] The frame 35 is equipped with a control component 6 for controlling the movement of the wing plate 50. The control component 6 includes an arc-shaped groove 60 opened on the inner side of the side plate 32. An inner frame 61 is slidably installed inside the frame 35. Several sleeves 62 are fixed at equal intervals on both sides of the inner frame 61. The sleeves 62 abut against the inner surface of the wing plate 50. First racks 63 are symmetrically fixed at both ends of the inner frame 61. Gears 64 are rotatably installed inside both ends of the frame 35. Second racks 65 are slidably installed inside both ends of the frame 35. The corresponding first racks 63 and second racks 65 are meshed with the gears 64. A linkage block 66 is slidably installed inside the end of the second rack 65. The linkage block 66 passes through the end of the frame 35, and one end of the linkage block 66 abuts against the inner side of the ice crushing tooth 39. The linkage block 66 is elastically connected to the second rack 65 through a second spring 67. A pulley 68 is installed at the other end of the linkage block 66. The pulley 68 abuts against the inner side of the side plate 32 and the inside of the arc-shaped groove 60. In this embodiment, outside the arc-shaped groove 60, the linkage block 66 protrudes from the end of the second rack 65. When the ice-crushing tooth 39 retracts towards the rotating shaft 33, the inner side of the ice-crushing tooth 39 abuts against the linkage block 66, thereby driving the second rack 65 to slide through the linkage block 66, which in turn drives the gear 64 to rotate. Finally, the first rack 63 drives the inner frame 61 to slide, and the inner frame 61 drives the sleeve 62 to slide. Each sleeve 62 pushes the wing plate 50, causing the wing plate 50 to rotate and unfold from a V-shape to a flat surface. In this way, when the ice-crushing tooth 39 retracts into the sleeve 35, the wing plate 50 immediately flattens out and contacts the roof of the van 1, increasing the contact area and reducing the local pressure on the roof of the van 1. Moreover, the outer surface of the wing plate 50... The rubber pad 55 makes flexible contact with the roof, further ensuring that the van 1 is not damaged by the ice-crushing mechanism 3. Initially, there is a certain distance between the linkage block 66 and the ice-crushing tooth 39. When the bottom of the ice-crushing tooth 39 enters the sleeve frame 35, it will abut against the linkage block 66, thereby driving the second rack 65 to move. This ensures that the retraction of the ice-crushing tooth 39 and the rotation of the wing plate 50 will not restrict each other and cause jamming. When the pulley 68 at the end of the linkage block 66 enters the arc groove 60, the linkage block 66 enters the interior of the second rack 65. Under the elastic force of the first torsion spring 51, the wing plate 50 will quickly reset, pushing the sleeve 62 back, causing the inner sleeve frame 61 to drive the first rack 63 to slide in the opposite direction, thereby driving the second rack 65 to reset through the gear 64.

[0026] Example 3: Please refer to Figure 6 , Figure 7 , Figure 10 and Figure 12 Based on Embodiment 1, this embodiment takes into account that in Embodiment 2, when the ice fragments are scraped off the surface of the ice-scraping teeth 39 by the wing plate 50, some ice fragments will be transferred to the surface of the flap plate 52 and the rubber pad 55, and there is still a risk that the ice fragments will freeze on the surface of the flap plate 52 and the rubber pad 55. Therefore, Embodiment 3 solves the problem of the risk of freezing even when some ice fragments are transferred to the surface of the flap plate 52 and the rubber pad 55 through the following structure. A flap 52 is rotatably mounted on the outer surface of the wing plate 50. A second torsion spring 53 is installed at the point where the flap 52 rotates with the wing plate 50. Pads 54 are fixed at equal intervals on the inner side of the flap 52. Rubber pads 55 are connected to the side of the flap 52 and the edge of the wing plate 50. In this embodiment, the flap 52 is rotatably connected to the wing plate 50 via the second torsion spring 53. The elastic force of the second torsion spring 53 causes the flap 52 to adhere tightly to the outer surface of the wing plate 50, thereby causing the rubber pad 55 to adhere to the outer surface of the wing plate 50. The rubber pad 55 can achieve flexible contact when the wing plate 50 contacts the roof of the van 1 to avoid damage to the roof, and can also generate vibration when the flap 52 flaps, thereby efficiently removing ice fragments.

[0027] Each set of support frames 34 is equipped with a vibration assembly 7 that drives the wing plate 50 to shake off the accumulated ice. The vibration assembly 7 includes a corrugated arc plate 70 fixed on each set of support frames 34. A top rod 71 is slidably arranged inside the sleeve 62. The top rod 71 passes through the sleeve frame 35, and one end of the top rod 71 abuts against the pad 54 inside the wing plate 50, while the other end of the top rod 71 abuts against the corrugated arc plate 70. A third spring 72 is installed on the top rod 71. In this embodiment, as Figure 6 As shown, the rotation direction of the "roller" is clockwise. After the ice-breaking teeth 39 have finished breaking the ice, after rotating 90 degrees, the top rod 71 protruding from the inner side of the sleeve frame 35 begins to contact the corrugated arc plate 70. The uneven surface of the corrugated arc plate 70 causes the top rod 71 to slide back and forth, thereby intermittently contacting the pad 54 inside the wing plate 50, causing the flap 52 to fan. The flap 52 drives the rubber pad 55 to alternately tighten and loosen, and the ice fragments attached to its surface fall off very easily.

[0028] A snow removal method using an integrated ice-breaking and snow-removing snow removal equipment includes the following steps: S1: The first hydraulic push rod 21 drives the lifting frame 22 to rise to the highest point, the van 1 drives into the appropriate position below the snowplow 20, the first hydraulic push rod 21 drives the lifting frame 22 to descend, so that the rubber strip 26 and the shovel 81 abut against the roof of the van 1. S2: Synchronously control the adjusting frame 24 and the de-icing component 8 to tilt the snowplow 25, the ice crushing mechanism 3 and the de-icing component 8 relative to the van 1 at a certain angle, and then adjust the length of the supercharger 31 so that the ice crushing teeth 39 press against the ice layer with a certain pressure. After being in place, the van 1 moves forward slowly, and the snowplow 25 and rubber strip 26 first scrape off the snow on the roof of the vehicle, exposing the ice layer. S3: The "roller" formed by the frame 35 and the ice-crushing tooth 39 rotates using the friction force of the van 1 when it is moving. Whenever the ice-crushing tooth 39 rotates to be close to the ice layer, the roller column 46 abuts against the pressure plate 42, making the ice-crushing tooth 39 unable to slide. The ice-crushing tooth 39 is rigidly connected to the frame 35, thereby generating enough pressure to break the ice layer. S4: When the ice-crushing tooth 39 reaches the bottom of the "roller", the roller column 46 slides to the bottom of the pressure relief plate 45. If the pressure of the ice-crushing tooth 39 exceeds the threshold, the second hydraulic push rod 40 drives the connecting arm 41 to retract upward, the pressure relief plate 45 releases the roller column 46, and the ice-crushing tooth 39 slides into the inner sleeve frame 35 to reduce the pressure of the ice-crushing tooth 39 on the roof and protect the roof. When sliding, the wing plate 50 removes ice fragments from the surface of the ice-crushing tooth 39. S5: When the ice-breaking tooth 39 slides, it drives the inner sleeve frame 61 to slide, causing the sleeve 62 to lift the wing plate 50. The rubber pad 55 on the outer surface of the wing plate 50 abuts against the roof surface, further reducing the impact. S6: The ice-crushing tooth 39 rotates to the arc groove 60, the linkage block 66 retracts, the arc groove 60 and the sleeve 62 reset, the wing plate 50 resets, and at the same time the top rod 71 abuts against the corrugated arc plate 70, forming a reciprocating sliding motion. By impacting the pad 54, the flap 52 is driven to fan, stretching the rubber pad 55, and the vibration is used to remove the ice attached to the outer surface of the wing plate 50. S7: The "roller" rotates in a cycle, breaking up the ice layer on the roof. The deflector 80 and the scraper 81 are behind the "roller" and scrape off the ice fragments. Working principle: First, the first hydraulic push rod 21 drives the lifting frame 22 to the highest position, and the mechanism fixed on the side of the lifting frame 22 rises together. The van 1 that needs snow removal and de-icing drives into the snow removal frame 20, so that the front of the van passes through the snow removal frame 20 and the head of the van is directly below the snow removal shovel 25. Then, the first hydraulic push rod 21 extends and the lifting frame 22 descends until the rubber strip 26 touches the top of the van 1. Adjust the extension length of the hydraulic rods on both sides of the mounting frame 23 so that the snow removal shovel 25, the ice crushing mechanism 3 and the de-icing component 8 are placed on the top of the van 1 at a uniform angle. Then adjust the length of the booster 31 so that the bottom ice crushing teeth 39 touch the ice layer with a certain pressure.

[0029] The van 1 moves slowly forward. Snowplows 25 and rubber strips 26 first scrape away the snow on the roof, exposing the ice layer. The snow moves along the tilted snowplows 25 to one side of the van 1 and falls to the ground. Next, the "roller" formed by the frame 35 rolls in the opposite direction to the van 1's direction of travel. The frame 35, connecting ring 36, and side plate 32 rotate relative to each other. Whenever the frame 35 rotates until the roller column 46 touches the pressure plate 42, the roller column 46 is squeezed by the pressure plate 42, causing the ice-crushing teeth 39 to slide out of the frame 35 and continue rolling in the sliding state. The slid-out ice-crushing teeth 39 contact the ice layer and crush it.

[0030] When the ice-crushing tooth 39 rolls to the bottom of the "roller", the roller column 46 rotates just below the pressure relief plate 45. If the pressure of the ice-crushing tooth 39 on the top surface of the van 1 does not exceed the threshold, the second hydraulic push rod 40 does not move, the pressure relief plate 45 remains stationary, and the roller column 46 and the ice-crushing tooth 39 continue to roll in their original state until they leave the range of the pressure relief plate 45. When the pressure of the ice-crushing tooth 39 on the top of the van 1 exceeds the threshold, the second hydraulic push rod 40 immediately drives the connecting arm 41 to move upward, causing the slider 44 to slide upward in the adjusting groove 43, and causing the pressure relief plate 45 to move upward. The pressure of the pressure relief plate 45 on the roller column 46 is reduced, and the ice-crushing tooth 39 quickly retracts into the sleeve frame 35 under the elastic force of the first spring 38, thereby reducing the pressure on the top of the van 1.

[0031] After the ice-crushing tooth 39 enters the sleeve frame 35, it abuts against the linkage block 66, thereby pulling up the second rack 65. The second rack 65, through the meshing of the gear 64 and the first rack 63, drives the inner sleeve frame 61 to slide down. The inner sleeve frame 61 drives the sleeve 62 to push the wing plate 50, and the wing plate 50 unfolds to a horizontal position. When the wing plate 50 unfolds, it drives the first torsion spring 51 to store force. After unfolding, the wing plate 50 replaces the ice-crushing tooth 39 to abut against the roof of the van 1. Since the area of ​​the wing plate 50 is larger than that of the ice-crushing tooth 39, the pressure on the roof is relatively reduced, thereby protecting the roof of the van 1 from being crushed and the paint surface damaged. At the same time, the rubber pad 55 on the surface of the wing plate 50 makes flexible contact with the roof surface, further improving the protective effect.

[0032] refer to Figure 6 The frame 35 containing the ice-crushing tooth 39 continues to roll clockwise. When the pulleys 68 protruding from both ends of the frame 35 enter the arc-shaped groove 60 inside the side plate 32, the linkage block 66 is pushed into the inside of the second rack 65 by the elastic force of the second spring 67, no longer resisting the inside of the ice-crushing tooth 39. Subsequently, under the elastic force of the first torsion spring 51, the wing plate 50 is reset, pushing the sleeve 62 and the inner frame 61 to reset in the opposite direction. The inner frame 61 drives the first rack 63 to reset, and the first rack 63 drives the second rack 65 to reset through the gear 64. After that, while the ice-crushing tooth 39 is inside the frame 35, the linkage block 66 is always inside the second rack 65.

[0033] Next, after rotating 90 degrees, the protruding push rod 71 on the sleeve 35 begins to abut against the corrugated arc plate 70. As the sleeve 35 continues to roll, the push rod 71 slides back and forth, cyclically compressing and releasing the third spring 72. The other end of the push rod 71 continuously slides into and out of the wing plate 50 and impacts the pad 54. When it impacts the pad 54, the flap 52 flaps, compressing the second torsion spring 53 and simultaneously pulling the rubber pad 55, causing the rubber pad 55 to continuously tighten and loosen, thereby shaking off the ice fragments on its surface and preventing the ice fragments from adhering for a long time.

[0034] After the top rod 71 passes the corrugated arc plate 70, everything returns to stillness. The ice-breaking tooth 39 is inside the sleeve frame 35, the wing plate 50 remains in a V-shape, and the flap 52 and rubber pad 55 are reattached to the outer surface of the wing plate 50.

[0035] Finally, the ice fragments broken by the ice-breaking teeth 39 are removed by the deflector plate 80 and the shovel plate 81 and fall to the ground from one side of the van 1.
