Description

Technical Field

[0001] This utility model belongs to the field of snow removal machine technology, and in particular relates to a fish scale roller type mechanical snow removal device. Background Technology

[0002] In the field of modern snow removal equipment, there are two main types of snowplows: plow-type and rotor-type. Plow-type snowplows push snow away with plow blades, but their effectiveness in handling hard and compacted snow is limited, and their snow removal distance is relatively short, restricting their application range. Rotary-type snowplows, on the other hand, use a rotating rotor to chop and throw the snow, effectively handling both hard and compacted snow.

[0003] Patent CN216108287U discloses a road de-icing device, including a de-icing mechanism. The de-icing mechanism includes a de-icing roller, which includes blades mounted on a roller. The blades are provided with cutting edges, which are spaced apart and distributed in a spiral pattern. A lifting arm is fixed to the rear of the de-icing mechanism, and an ice-pushing plate is bolted to the bottom of the lifting arm. The blades of the de-icing mechanism are similar in shape to rollers, and they break up the ice layer through rotational motion. The ice-pushing plate is used to push the broken ice and snow to both sides of the road in a timely manner.

[0004] The above-mentioned technical solution uses a de-icing roller to rotate and cut and compact the snow and ice layer. Although it can break the ice layer to a certain extent, its movement mode is singular. It relies solely on rotational cutting and cannot completely break and loosen the ice layer, resulting in a large amount of residue. Especially when the ice layer is thick or the degree of compaction is high, it cannot completely break the ice layer, resulting in an unsatisfactory snow removal effect.

[0005] To address this problem, we propose a fish-scale roller-type mechanical snow removal device. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that existing snow removal devices cannot completely break up ice layers when the ice layer is thick or highly compacted, resulting in unsatisfactory snow removal effects. Therefore, a fish-scale roller type mechanical snow removal device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A fish-scale roller type mechanical snow removal device includes a telescopic arm assembly, a snowplow bucket, and an ice-breaking assembly, wherein:

[0009] The telescopic boom assembly is mounted on the excavator support beam and is used to control the height of the snowplow bucket and the ice-breaking assembly;

[0010] The snowplow bucket has a C-shaped structure, and the lower edge of the snowplow bucket has a cutting edge;

[0011] The ice-breaking assembly includes two symmetrically arranged mounting discs, which are fixed to the side wall of the snowplow by channel steel. A fish-scale ice-crushing roller is rotatably arranged between the two mounting discs, and a drive motor is fixedly installed on one of the mounting discs. The drive motor is connected to the fish-scale ice-crushing roller in a transmission connection.

[0012] The mounting plate is equipped with a damping structure for controlling the axial reciprocating motion of the fish-scale ice-crushing roller. While the drive motor drives the fish-scale ice-crushing roller to rotate circumferentially to crush ice, the fish-scale ice-crushing roller is axially oscillating to break the ice.

[0013] Preferably, the telescopic boom assembly includes two sets of linkage structures. Each linkage structure includes a connecting frame, on which a main boom, a first hydraulic cylinder, and a second hydraulic cylinder are rotatably mounted. The telescopic end of the first hydraulic cylinder is rotatably connected to the main boom, and the telescopic end of the second hydraulic cylinder is rotatably mounted with a forearm. One end of the forearm is rotatably connected to the main boom, and the other end is rotatably connected to a pull rod. The ends of the main boom and the pull rod are both rotatably connected to the snowplow bucket.

[0014] Preferably, the inner wall of the snowplow bucket is an inclined curved surface with a drop at both ends.

[0015] Preferably, the fish-scale ice-crushing roller includes two assembled shafts, which are coaxially and symmetrically arranged. Each assembled shaft includes multiple mounting pieces, which are fixedly connected by two connecting shafts. A support shaft is provided on the side of the outermost mounting piece, and the support shaft is rotatably connected to the mounting plate. The mounting pieces on the two assembled shafts are spaced apart, and the mounting pieces are slidably connected to the support shaft on the other assembled shaft. Multiple mounting strips are equidistantly arranged on the outer periphery of each mounting piece, and the mounting strips on different assembled shafts are spaced apart. Multiple evenly distributed scrapers are provided outside the mounting strips.

[0016] Preferably, the shovel has a front shovel portion facing the direction of rotation and side shovel portions on both sides.

[0017] Preferably, the abutting structure includes a pressure ring fixedly installed inside the mounting plate. The surface of the pressure ring is wavy, with the crest of one pressure ring corresponding to the trough of another pressure ring. The connecting shaft extends to the pressure ring and abuts against the surface of the pressure ring.

[0018] Preferably, a hexagonal connecting hole is provided near the center of the support shaft of the drive motor, and the output end of the drive motor is connected to an output shaft that matches the connecting hole.

[0019] In summary, the technical effects and advantages of this utility model are as follows: the fish-scale roller-type mechanical snow removal device can not only rotate but also swing axially. By increasing the lateral displacement, the blade forms a Z-shaped path while rotating, allowing it to cover a larger area during the cutting process and improving snow removal efficiency. Especially for thick ice layers or highly compacted ice-snow mixtures, when the blade cuts into the ice layer, the axial swing can further break and loosen the ice layer, causing it to detach from the ground. This significantly improves the breaking effect on compacted snow and ice layers and reduces the amount of residue.

[0020] This fish-scale roller-type mechanical snow removal device combines the function of a subsequent snowplow. After the ice layer is broken and loosened by the fish-scale ice-crushing roller, the snowplow can concentrate the broken ice and snow and push it to one side, which not only improves the efficiency of snow removal but also reduces the amount of ice and snow residue, making the snow removal operation more thorough. The coordinated work of the snowplow and the fish-scale ice-crushing roller makes the entire snow removal process smoother and can adapt to various complex ice and snow environments.

[0028] 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.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1 A fish-scale roller type mechanical snow removal device includes a telescopic arm assembly 1, a snowplow bucket 2, and an ice-breaking assembly 3. The telescopic arm assembly 1 is connected to the snowplow bucket 2 to an excavator, and the ice-breaking assembly 3 is installed on the snowplow bucket 2.

[0031] The telescopic boom assembly 1 is installed on the excavator support beam and is used to control the height of the snowplow 2 and the ice-breaking assembly 3, so that the snowplow 2 and the ice-breaking assembly 3 can be adaptively adjusted according to the snow thickness and road terrain, thereby improving the applicability of the device.

[0032] Reference Figure 1 The telescopic boom assembly 1 includes two sets of linkage structures. The linkage structure includes a connecting frame 11, on which a boom 12, a first hydraulic cylinder 13, and a second hydraulic cylinder 14 are rotatably mounted. The telescopic end of the first hydraulic cylinder 13 is rotatably connected to the boom 12, and the telescopic end of the second hydraulic cylinder 14 is rotatably mounted with a forearm 15. One end of the forearm 15 is rotatably connected to the boom 12, and the other end is rotatably connected to a tie rod 16. The ends of the boom 12 and the tie rod 16 are both rotatably connected to the snowplow 2. The first hydraulic cylinder 13 and the second hydraulic cylinder 14 are connected to the hydraulic system of the excavator, controlling the telescopic movement of the first hydraulic cylinder 13 and the second hydraulic cylinder 14. By telescopically moving the first hydraulic cylinder 13, the angle of the boom 12 can be adjusted, thereby adjusting the height of the snowplow 2 and the ice-breaking component 3. By telescopically moving the second hydraulic cylinder 14, the forearm 15 is rotated, driving the tie rod 16 to move, thereby controlling the snow-shoveling angle of the snowplow 2 and the ice-breaking component 3, which is beneficial for snow-shoveling operations on roads with different slopes.

[0033] Reference Figure 1-2 The snowplow hopper 2 has a C-shaped structure. The C-shaped structure of the snowplow hopper 2 can better accommodate and concentrate the ice and snow broken by the ice-breaking component 3, so that the ice and snow can smoothly enter the snowplow hopper 2. The lower edge of the snowplow hopper 2 has a cutting edge. The cutting edge design of the lower edge of the snowplow hopper 2 can easily cut into the ice and snow layer. The inner wall of the snowplow hopper 2 is an inclined curved surface with a drop at both ends, which can naturally guide the ice and snow entering the snowplow hopper 2 to one side of the snowplow hopper 2, thereby realizing continuous operation, avoiding excessive snow accumulation, reducing the possibility of ice and snow accumulating at the mouth of the snowplow hopper 2, and improving snow removal efficiency.

[0034] Reference Figure 1-5The ice-breaking component 3 includes two symmetrically arranged mounting discs 31. The mounting discs 31 are fixed to the side wall of the snowplow 2 via channel steel. A fish-scale ice-crushing roller 32 is rotatably arranged between the two mounting discs 31. A drive motor 33 is fixedly installed on one of the mounting discs 31. The drive motor 33 is connected to the fish-scale ice-crushing roller 32. The drive motor 33 drives the fish-scale ice-crushing roller 32 to rotate, which can break up the thick snow and ice layer on the road surface.

[0035] The mounting plate 31 is equipped with a damping structure for controlling the axial reciprocating motion of the fish-scale ice-crushing roller 32. While the drive motor 33 drives the fish-scale ice-crushing roller 32 to rotate circumferentially to crush ice, the fish-scale ice-crushing roller 32 also swings axially to break ice. The fish-scale ice-crushing roller 32 can not only rotate but also swing axially. By increasing the lateral displacement motion, the fish-scale ice-crushing roller 32 forms a Z-shaped path while rotating, which allows the fish-scale ice-crushing roller 32 to cover a larger area during the cutting process, improving snow removal efficiency. Especially for ice layers that are thick or highly compacted mixed layers of snow and ice, it significantly improves the crushing effect on compacted snow and ice layers and reduces the amount of residue.

[0036] Reference Figure 1-5 The fish-scale ice crushing roller 32 includes two assembled shafts 321, which are coaxially and symmetrically arranged, and can slide axially between each other.

[0037] The assembly shaft component 321 includes multiple mounting pieces 3211, which are fixedly connected by two connecting shafts 3212. A support shaft 3213 is provided on the side of the outermost mounting piece 3211. The support shaft 3213 is rotatably connected to the mounting plate 31, and the support shaft 3213 and the mounting plate 31 can be displaced axially to ensure that the fish scale ice crushing roller 32 can swing axially. The mounting pieces 3211 on the two assembly shaft components 321 are spaced apart, and the mounting pieces 3211 are slidably connected to the support shaft 3213 on the other assembly shaft component 321. The spaced mounting pieces 3211 improve the connection stability between the two sets of assembly shaft components 321. Multiple mounting strips 3214 are equidistantly arranged on the outer periphery of the mounting plate 3211. The mounting strips 3214 on different assembly shafts 321 are spaced apart. Multiple evenly distributed shovels 3215 are arranged outside the mounting strips 3214. When the fish scale ice crushing roller 32 rotates, the two assembly shafts 321 swing back and forth in opposite directions through the action of the abutment structure. Since the mounting strips 3214 on different assembly shafts 321 are spaced apart, the two adjacent mounting strips 3214 are always in a state of opposite movement. After the shovels 3215 on different mounting strips 3214 scrape into the ice layer, the relative movement generates a clamping force on the ice layer, making the hard ice layer easier to break and separate from the road surface, thus improving the ice breaking effect.

[0038] Reference Figure 5The shovel 3215 has a front shovel portion facing the direction of rotation and side shovel portions on both sides. The front shovel portion is conducive to penetrating the ice layer when the shovel 3215 rotates, and the side shovel portions are conducive to squeezing and breaking the ice layer when the shovel 3215 swings in a Z-shape.

[0039] Reference Figure 1-5 The abutting structure includes a pressure ring 34 fixedly installed inside the mounting plate 31. The surface of the pressure ring 34 is wavy, with the crest of one pressure ring 34 corresponding to the trough of the other pressure ring 34. Therefore, the distance between corresponding positions of the two pressure rings 34 is the same, and this distance is consistent with the length of the connecting shaft 3212. The connecting shaft 3212 extends to the pressure ring 34 and abuts against the surface of the pressure ring 34. When the drive motor 33 drives the fish scale ice crushing roller 32 to rotate, the connecting shaft 3212 continuously changes its position relative to the pressure ring. Position 34 causes the blade 3215 to oscillate back and forth along the wavy contour of the pressure ring 34, forming a Z-shaped path as it rotates. This allows the blade 3215 to cover a larger area during the cutting process, improving snow removal efficiency. Especially for thick ice layers or highly compacted ice-snow mixtures, when the blade 3215 cuts into the ice layer, the axial oscillation can further break and loosen the ice layer, causing it to detach from the ground. This significantly improves the breaking effect on compacted snow and ice layers and reduces the amount of residue.

[0040] Reference Figure 3 and 6 A hexagonal connecting hole 3216 is provided at the center of the support shaft 3213 near the drive motor 33. The output end of the drive motor 33 is connected to an output shaft 331 that is compatible with the connecting hole 3216. Through the cooperation between the hexagonal connecting hole 3216 and the output shaft 331, the hexagonal structure can ensure the axial displacement of the support shaft 3213 while ensuring effective transmission, thereby adapting to the swing ice-breaking mode of the fish scale ice crushing roller 32.

[0041] Working principle:

[0042] In use, the height of the snowplow bucket 2 and the ice-breaking component 3 is controlled by the telescopic arm assembly 1, so that the blade of the snowplow bucket 2 is in contact with the road surface, and the blade 3215 can embed itself into the ice layer. The drive motor 33 is started, and the excavator is driven to move along the snow removal path. The output shaft 331 drives the support shaft 3213 to rotate, so that the fish-scale ice-breaking roller 32 starts to rotate. When the blade 3215 rotates, the front blade penetrates the ice layer to break the ice. At the same time, when the drive motor 33 drives the fish-scale ice-breaking roller 32 to rotate, the connecting shaft 3212 continuously changes its position with the pressure ring 34, so it will swing back and forth along the wavy contour of the surface of the pressure ring 34, so that the blade 3215 forms a Z-shaped path while rotating, which allows the blade 3215 to cover a larger area during the cutting process and improves the snow removal efficiency.

[0043] As the excavator moves, the snowplow bucket 2 can accommodate and concentrate the ice and snow broken by the ice-breaking component 3, allowing the ice and snow to smoothly enter the snowplow bucket 2. The ice and snow entering the snowplow bucket 2 are naturally guided to one side of the snowplow bucket 2, thereby achieving continuous operation, avoiding excessive snow accumulation, reducing the possibility of ice and snow accumulating at the opening of the snowplow bucket 2, and improving snow removal efficiency.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
