Description

Technical Field

[0001] This invention specifically relates to an angle-adjustable elastic buffer snowplow, and pertains to the field of snowplows. Background Technology

[0002] Snowplows, also known as snowplows, snow shovels, and snow shovels, are snow removal attachments that are installed at the front of a vehicle or used by hand. They use the forward thrust provided by the chassis equipment to push the snow on the road surface to the sides of the road or a designated area, enabling large-scale and continuous mechanized snow removal operations. They are one of the most widely used basic equipment in road maintenance, factory cleaning, and snow removal in public squares in northern regions. A snowplow with publication number CN115748564A is mounted on the front of an articulated all-terrain two-section tracked vehicle. The snowplow includes a snowplow, a support frame, a hydraulic cylinder, and a locking rod. The support frame is fixedly connected to the snowplow, and one end of the support frame has a rotating shaft rotatably connected to the front vehicle. One end of the hydraulic cylinder is rotatably connected to the snowplow, and the other end is rotatably connected to the front vehicle. The hydraulic cylinder is configured to drive the snowplow to rotate around the rotating shaft. The locking rod is detachably connected to both the snowplow and the front vehicle. This snowplow is better suited for snow removal in complex off-road terrain and extremely cold conditions in the Arctic and Antarctic regions. It features a simple structure, easy maintenance, few parts, and low cost. The locking rod locks the snowplow in place when it is not in operation, preventing movement and improving safety. In existing equipment, traditional snowplows have a rigid and fixed overall structure and do not have the ability to adjust their angles. When encountering uneven road surfaces, thick snow clumps, and hard snow protrusions during operation, the blades do not adhere well to the ground, resulting in snow leakage and incomplete snow pushing. Furthermore, the rigid load-bearing structure cannot buffer instantaneous impact loads, and long-term operation can easily cause blade deformation. Summary of the Invention

[0003] To address the aforementioned problems, a technical solution is proposed: an angle-adjustable elastic buffer snowplow, comprising: A connecting mechanism and a shovel plate mechanism are provided, and a buffer mechanism and a top support mechanism are installed between the connecting mechanism and the shovel plate mechanism, with the top support mechanism located above the buffer mechanism; The snowplow mechanism includes a snowplow blade, both its upper and lower ends of which are curved away from the connecting mechanism. An arc-groove plate is fixedly installed at the bottom of the snowplow blade, and arc grooves are formed on both sides of the top of the arc-groove plate. A rotating plate is installed at the end of the arc-groove plate away from the snowplow blade. Inner sliding columns are fixedly installed on both sides of the inner wall of the rotating plate. The rotating plate slides and adapts to the arc grooves of the arc-groove plate through the inner sliding columns. A snowplow blade is fixedly installed at the end of the rotating plate away from the arc-groove plate. Pressure strips are fixedly installed on both the upper and lower sides of the arc-groove plate. The arc grooves of the arc-groove plate and the inner sliding columns on the inner side of the rotating plate form a sliding adaptation structure. Under conditions where the road surface is uneven, the rotating plate... The moving end snowplow blade allows for slight sliding adjustment of its angle, ensuring a tight fit with the ground and solving the problems of poor road adaptability and snow leakage on uneven surfaces caused by traditional snowplows. Simultaneously, pressure strips on the upper and lower sides of the arc-groove plate radially limit the rotating plate, preventing slippage and ensuring the stability of adaptive adjustment. Furthermore, the elastic inner pad between the pressure strip and the rotating plate undergoes elastic deformation when the snowplow blade is in contact with the ground, sliding, or subjected to ground impacts, buffering ground vibrations and impacts and reducing friction and wear. The inner wall of the pressure strip is fitted to the outer side of the rotating plate, and an inner pad made of elastic material is fixedly installed between the inner wall of the pressure strip and the end of the rotating plate furthest from the snowplow blade.

[0004] Preferably, a slanted guide plate is fixedly installed on the side of the snowplow away from the connecting mechanism. The slanted guide plate is evenly installed on the outer side of the snowplow. The structure design of the upper and lower ends of the snowplow is curved outwards to gather the snow in front, prevent the snow from falling randomly to both sides, and increase the amount of snow pushed in one go. At the same time, the slanted guide plates are evenly and symmetrically arranged on the outer side of the snowplow, and the top of the slanted guide plate is inclined towards the center of the snowplow axis. This can guide the gathered snow to the center and gather it neatly, further avoiding side leakage and improving the flatness of the snowplow. The slanted guide plates are symmetrically installed along the center position of the snowplow axis, and the top of the slanted guide plates is inclined towards the center position of the snowplow axis.

[0005] Preferably, the connecting mechanism includes a connecting beam, one end of which is fixedly mounted with a snap-fit ​​plate, a support plate is fixedly mounted on the outer side of the snap-fit ​​plate, a bottom support plate is fixedly mounted on the bottom of the support plate, and a bottom pad is fixedly mounted on the side of the bottom support plate near the snowplow, the side of the bottom pad near the snowplow is curved, and the curved surface of the bottom pad fits snugly against the curved surface of the bottom of the side of the snowplow near the bottom pad.

[0006] Preferably, the top support mechanism includes a horizontal groove plate, which is fixedly installed on the top of the support plate near the snowplow. Shaft groove plates are fixedly installed on both sides of the horizontal groove plate near the snowplow. A top pressure plate is rotatably installed between the shaft groove plates via a rotating shaft. The side of the top pressure plate near the snowplow is a concave arc surface, and the arc surface of the top pressure plate fits against the arc surface of the top of the snowplow on the side away from the inclined guide plate. A support strip is fixedly installed on the top of the shaft groove plate, and a leaf spring is fixedly installed on the top of the support strip. The leaf spring is evenly installed axially on the top of the support strip. Utilizing the arc-shaped bottom pad on the inner side of the bottom support plate of the support plate, it engages with the bottom of the snowplow through an arc-shaped fit, providing limiting support for the bottom of the shovel mechanism and preventing the bottom of the shovel from shaking or shifting during snowplowing operations. The end of the leaf spring away from the support strip is fixedly connected to the side of the top pressure plate away from the snowplow.

[0007] Preferably, the buffer mechanism includes a connecting shaft plate and a support frame. The connecting shaft plate is fixedly installed at the center of the support plate near the snowplow. The support frame is fixedly installed on the support plate near the snowplow and is symmetrically installed along the center of the axis of the support plate. A fixing plate is fixedly installed on the side of the support plate near the snowplow, and the fixing plate is located inside the support frame. A fixing groove plate is rotatably installed on the end of the connecting shaft plate away from the support plate via a shaft. The side of the fixing groove plate near the snowplow is fixedly connected to the outer side of the snowplow. Connecting blocks are fixedly installed at both ends of the side of the snowplow plate near the support frame. An inclined panel is fixedly installed on the side of the connecting block away from the snowplow.

[0008] Preferably, the side of the inclined panel away from the connecting block is a centrally protruding inclined surface. A limiting plate is fixedly installed on the side of the support frame near the inclined panel. The side of the limiting plate near the inclined panel is also an inclined surface, and the inclined surface of the limiting plate fits against the bottom of the inclined surface of the inclined panel. A column groove plate is fixedly installed on the top of the inclined surface of the inclined panel. Column grooves are symmetrically formed on the top of the column groove plate. Through the cooperation of the support frames on both sides of the support plate, the fixing plate, the fixing column, and the column groove plate, and with the spring between the fixing plate and the column groove plate, buffer adjustment is performed. During normal road leveling operations, the spring remains in a pre-tensioned state to maintain the standard operation of the shovel. The angle ensures snow-pushing accuracy. When encountering high-intensity impact conditions such as thick snow, hard snow, and road surface protrusions, the snow-pushing plate is compressed, causing the connecting block, inclined plate, and column groove plate to shift as a whole. The compression spring undergoes compression deformation, which, in conjunction with the synchronous deformation of the top leaf spring, allows the snow-pushing plate to adjust its tilt angle slightly to buffer the instantaneous impact load and prevent rigid pushing from causing the snow-pushing plate to bend and the structure to crack. A fixing column is fixedly installed on the top of the fixing plate. The fixing column is symmetrically installed along the center position of the axis of the fixing plate, and the outer side of the fixing column slides and adapts to the column groove of the column groove plate. A spring is fixedly installed between the column groove plate and the fixing plate.

[0009] This invention provides an angle-adjustable elastic buffer snowplow, which has the following beneficial effects: (i) The arc groove of the arc groove plate and the inner sliding column of the rotating plate form a sliding adaptation structure. Under the condition of uneven road surface, the rotating plate drives the end snowplow to slide slightly to adjust the angle, ensuring that the snowplow is in close contact with the ground. This solves the problem of poor road surface adaptability of traditional snowplows and snow leakage on uneven road surfaces. At the same time, the pressure strips on the upper and lower sides of the arc groove plate radially limit the rotating plate to prevent slippage and deviation during sliding, ensuring the stability of adaptive adjustment. Meanwhile, the elastic inner pad between the pressure strip and the rotating plate can generate elastic deformation when the snowplow is in contact with the ground, sliding adjustment, and is impacted by the ground, buffering ground vibration and impact force, and reducing friction and wear.

[0010] (ii) The outward curved design of the upper and lower ends of the snowplow can gather the snow in front and prevent the snow from falling randomly to both sides, thereby increasing the amount of snow pushed in one go. At the same time, the inclined guide plates are evenly and symmetrically arranged on the outside of the snowplow, and the top of the inclined guide plates is inclined towards the center of the snowplow axis. This can guide the gathered snow in a directional manner, gather the snow towards the center and make it neat, further avoiding the problem of side leakage and improving the flatness of the snowplow.

[0011] (iii) Using the arc-shaped bottom pad on the inner side of the bottom support plate of the support plate, the arc-shaped pad fits into the bottom of the snowplow to limit the bottom of the shovel mechanism and prevent the bottom of the shovel from shaking and shifting during snowplowing operations.

[0012] (iv) Through the cooperation of the support frame on both sides of the support plate, the fixed plate, the fixed column and the column groove plate, and the spring between the fixed plate and the column groove plate, the buffer adjustment is carried out. During normal road leveling operations, the spring is kept in a pre-tight state to maintain the standard working angle of the shovel and ensure the snow pushing accuracy. When encountering high-intensity impact conditions such as thick snow, hard snow, and road protrusions, the snow pushing plate is pressed and drives the connecting block, the inclined plate and the column groove plate to move as a whole, squeezing the spring to undergo compression deformation. With the synchronous deformation of the top leaf spring, the shovel tilt angle is adjusted slightly to buffer the instantaneous impact load and avoid rigid pushing to prevent the shovel from bending and the structure from cracking.

[0015] Example 1, Reference Figures 1 to 2 and Figures 8 to 10 The present invention provides this technical solution: An angle-adjustable, elastically cushioned snowplow includes: A connecting mechanism 1 and a shovel plate mechanism 3 are connected, and a buffer mechanism 4 and a top support mechanism 2 are installed between the connecting mechanism 1 and the shovel plate mechanism 3. The top support mechanism 2 is located above the buffer mechanism 4. The snowplow mechanism 3 includes a snowplow 31. Both the upper and lower ends of the snowplow 31 are curved away from the connecting mechanism 1. An arc-groove plate 33 is fixedly installed at the bottom of the snowplow 31, and arc grooves are formed on both sides of the top of the arc-groove plate 33. A rotating plate 34 is installed at the end of the arc-groove plate 33 away from the snowplow 31. Inner sliding columns 37 are fixedly installed on both sides of the inner wall of the rotating plate 34. The rotating plate 34 slides and adapts to the arc grooves of the arc-groove plate 33 through the inner sliding columns 37. A snowplow 36 is fixedly installed at the end of the rotating plate 34 away from the arc-groove plate 33. Pressure strips 35 are fixedly installed on both the upper and lower sides of the arc-groove plate 33. The inner wall of the pressure strips 35 fits against the outer side of the rotating plate 34. The snowplow 31 is curved outwards at both the upper and lower ends to gather snow and prevent it from scattering laterally. The outer side of the snowplow 31 is evenly and symmetrically distributed with… Multiple sets of inclined guide plates 32 are provided, with the top of the inclined guide plates 32 tilted towards the center of the snowplow plate 31 axis. During the snowplowing process, the inclined guide plates 32 guide the gathered snow, gathering the snow from both sides towards the center, preventing the snow from scattering from both sides, improving the snowplowing effect, and ensuring the flatness of the snowplow. The bottom end of the snowplow plate 31 is fixed with an arc groove plate 33. The arc groove plate 33 forms a sliding adaptation structure with the inner sliding column 37 of the rotating plate 34 through the arc grooves on both sides. If there are undulations and unevenness on the ground, the rotating plate 34 can slide slightly along the arc groove of the arc groove plate 33 through the inner sliding column 37, driving the snowplow plate 36 at the end to adaptively adjust the contact angle, ensuring that the snowplow plate 36 is always in contact with the ground. An inner pad strip 38 is fixedly installed between the inner wall of the pressure strip plate 35 and the end of the rotating plate 34 away from the snowplow plate 36. The inner pad strip 38 is made of elastic material.

[0016] A slanted guide plate 32 is fixedly installed on the side of the snowplow 31 away from the connecting mechanism 1. The slanted guide plate 32 is evenly installed on the outer side of the snowplow 31. The pressure strips 35 on the upper and lower sides of the arc groove plate 33 fit against the outer side of the rotating plate 34 to achieve radial limiting and prevent the rotating plate 34 from slipping and shifting. The elastic inner pad 38 between the pressure strip 35 and the rotating plate 34 can be elastically deformed by pressure when the rotating plate 34 slides and is impacted by the ground, buffering vibration and impact force and reducing wear. The slanted guide plate 32 is symmetrically installed at the center position of the axis of the snowplow 31, and the top of the slanted guide plate 32 is inclined towards the center position of the axis of the snowplow 31.

[0017] Example 2, based on Example 1, with reference to Figures 3 to 5The connecting mechanism 1 includes a connecting beam 11, with a snap-fit ​​plate 13 fixedly installed at one end of the connecting beam 11. A support plate 12 is fixedly installed on the outer side of the snap-fit ​​plate 13, and a bottom support plate 14 is fixedly installed at the bottom of the support plate 12. A bottom pad plate 15 is fixedly installed on the side of the bottom support plate 14 near the snowplow 31. The connecting beam 11 and the snap-fit ​​plate 13 cooperate to snap-fit ​​and fix the mechanism to the walking device. The support plate 12 fixed on the outer side of the snap-fit ​​plate 13 serves as the core bearing plate, bearing the thrust of the equipment and providing an installation carrier for the top support mechanism 2 and the buffer mechanism 4. The arc-shaped bottom pad 15 on the inner side of the bottom support plate 14 at the bottom of the support plate 12 fits the arc-shaped bottom surface of the snowplow 31 through the arc structure, and provides limiting support for the bottom of the shovel mechanism 3 to prevent the bottom from shaking and shifting during snowplowing operations. The horizontal groove plate 21 is fixed to the top of the support plate 12. The top pressure plate 25 is rotatably installed between the symmetrically arranged shaft groove plates 22 on both sides through a rotating shaft. The side of the bottom pad 15 near the snowplow 31 is arc-shaped, and the arc surface of the bottom pad 15 fits the arc surface of the bottom of the snowplow 31 near the bottom pad 15.

[0018] The top support mechanism 2 includes a horizontal groove plate 21, which is fixedly installed on the top of the support plate 12 near the snowplow 31. Shaft groove plates 22 are fixedly installed on both sides of the horizontal groove plate 21 near the snowplow 31. A top pressure plate 25 is rotatably installed between the shaft groove plates 22 via a rotating shaft. The side of the top pressure plate 25 near the snowplow 31 is a concave arc surface, and this arc surface fits against the arc surface of the top of the snowplow 31 on the side away from the inclined guide plate 32. The concave arc surface on the inner side of the top pressure plate 25 fits against the top arc surface of the snowplow 31, thus pressing and positioning the snowplow 31 from the top and limiting the backward tilting of the shovel. A support bar 23 at the top of the shaft groove plate 22 supports a leaf spring 24. One end of the leaf spring 24 is fixed to the support bar 23 and the other end is connected to the top pressure plate 25. When the snow pushing operation generates vibration and impact force, or when the snowplow mechanism 3 is adjusted at a small angle, the top pressure plate 25 can tilt and rotate with the snowplow 31, while squeezing the leaf spring 24. The elastic deformation of the leaf spring 24 absorbs the top impact force, avoiding rigid collision and deformation of the snowplow 31, while ensuring the flexibility of the snowplow angle adjustment. The support bar 23 is fixedly installed on the top of the shaft groove plate 22, and the leaf spring 24 is fixedly installed on the top of the support bar 23. The leaf spring 24 is evenly installed axially on the top of the support bar 23, and the end of the leaf spring 24 away from the support bar 23 is fixedly connected to the side of the top pressure plate 25 away from the snowplow 31.

[0019] Example 3, based on Examples 1 and 2, with reference to Figures 6 to 7The buffer mechanism 4 includes a connecting shaft plate 41 and a support frame 43. The connecting shaft plate 41 is fixedly installed at the center of the support plate 12 near the snowplow 31. The support frame 43 is fixedly installed on the support plate 12 near the snowplow 31, and the support frame 43 is symmetrically installed along the center of the axis of the support plate 12. A fixing plate 44 is fixedly installed on the side of the support plate 12 near the snowplow 31, and the fixing plate 44 is located inside the support frame 43. A fixing groove plate 42 is rotatably installed on the end of the connecting shaft plate 41 away from the support plate 12 via a shaft. The side of the fixing groove plate 42 near the snowplow 31 is fixedly connected to the outer side of the snowplow 31. The connecting shaft plate 41 at the center of the support plate 12 is rotatably installed with the fixing groove plate 42 via a shaft, and the fixing groove plate 42 is fixedly connected to the snowplow 31, so that the entire shovel mechanism 3 can rotate slightly around the shaft, providing a structural basis for angle adjustment. The support frames 43 are symmetrically installed on both sides of the support plate 12. 3. The top of the fixed plate 44 inside the support frame 43 is fixed with symmetrically arranged fixed columns 46. The fixed columns 46 are slidably adapted to the column groove of the column groove plate 48. The column groove plate 48 and the fixed plate 44 are equipped with springs 45. During normal snow pushing, the springs 45 are in a pre-tight state to maintain the working angle of the shovel. When encountering thick snow, hard snow or ground protrusions that generate impact loads, the snow pushing plate 31 is pressed and drives the connecting block 47, the inclined plate 49 and the column groove plate 48 to move as a whole, so that the column groove plate 48 slides along the fixed column 46 and squeezes the spring 45. Through the compression deformation of the spring 45, the shovel mechanism 3 rotates. With the deformation of the leaf spring 24 of the top support mechanism 2, the shovel mechanism 3 can be adjusted slightly backward to buffer the instantaneous impact pressure and avoid rigid pushing that causes the shovel to deform. The two ends of the snow pushing plate 31 near the support frame 43 are fixedly installed with connecting blocks 47, and the side of the connecting block 47 away from the snow pushing plate 31 is fixedly installed with an inclined plate 49.

[0020] The inclined plate 49 has a centrally protruding inclined surface on the side away from the connecting block 47. A limiting plate 410 is fixedly installed on the side of the support frame 43 near the inclined plate 49. The side of the limiting plate 410 near the inclined plate 49 is also inclined, and the inclined surface of the limiting plate 410 fits against the bottom of the inclined surface of the inclined plate 49. A column groove plate 48 is fixedly installed on the top of the inclined surface of the inclined plate 49. Column grooves are symmetrically opened on the top of the column groove plate 48. A fixing column 46 is fixedly installed on the top of the fixing plate 44. When the impact load disappears, the spring 45 elastically returns to its original position. The moving shovel plate mechanism 3 automatically returns to the initial working angle. The top of the inclined plate 49 has a central protruding inclined surface. The inclined surface of the limiting plate 410 on the inner side of the support frame 43 fits against the bottom of the inclined plate 49, limiting the maximum backward tilt angle of the shovel plate, preventing the spring 45 from being over-compressed, and preventing the shovel plate from shaking and shifting, thus ensuring the stability of the angle adjustment. The fixing column 46 is symmetrically installed at the center position of the axis of the fixing plate 44, and the outer side of the fixing column 46 slides and adapts to the column groove of the column groove plate 48. A spring 45 is fixedly installed between the column groove plate 48 and the fixing plate 44.

[0021] In the connecting mechanism 1 and the top support mechanism 2, the connecting beam 11 cooperates with the snap-fit ​​plate 13 to snap and fix it to the walking equipment. The support plate 12 fixed on the outside of the snap-fit ​​plate 13 serves as the core bearing plate, bearing the thrust of the equipment and providing an installation carrier for the top support mechanism 2 and the buffer mechanism 4. The arc-shaped bottom pad 15 on the inner side of the bottom support plate 14 at the bottom of the support plate 12 fits the arc-shaped bottom surface of the snowplow 31 through the arc structure, providing limiting support for the bottom of the shovel mechanism 3 and preventing the bottom from shaking and shifting during snowplowing operations. The transverse groove plate 21 is fixed to the top of the support plate 12, and the shaft groove plates 22 symmetrically arranged on both sides are rotatably installed between each other through a rotating shaft. The top pressure plate 25 has a concave arc surface on its inner side that fits against the top arc surface of the snowplow 31, pressing and positioning the snowplow 31 from the top to limit the backward tilting of the shovel. The support bar 23 at the top of the shaft groove plate 22 supports the leaf spring 24. One end of the leaf spring 24 is fixed to the support bar 23 and the other end is connected to the top pressure plate 25. When the snowplowing operation generates vibration and impact force, or when the shovel mechanism 3 is adjusted at a small angle, the top pressure plate 25 can tilt and rotate with the snowplow 31, while squeezing the leaf spring 24. The elastic deformation of the leaf spring 24 absorbs the top impact force, avoiding rigid collision deformation of the snowplow 31, while ensuring the flexibility of the shovel angle adjustment.

[0022] In the snowplow mechanism 3, the snowplow 31 has outward curved ends to gather snow and prevent it from scattering laterally. Multiple sets of inclined guide plates 32 are evenly and symmetrically arranged on the outer side of the snowplow 31, with the tops of the guide plates 32 inclined towards the center of the snowplow 31's axis. During snowplowing, the guide plates 32 guide the gathered snow, converging it from both sides towards the center to prevent it from scattering and improve the snowplowing effect. This also ensures the smoothness of the snowplowing process. An arc-groove plate 33 is fixed to the bottom of the snowplow 31, and the arc-groove plate 33 slides against the inner sliding post 37 of the rotating plate 34 via its two side arc grooves. With an adaptable structure, if the ground is uneven or bumpy, the rotating plate 34 can slide slightly along the arc groove of the arc groove plate 33 via the inner sliding column 37, causing the snowplow 36 at the end to adaptively adjust the contact angle, ensuring that the snowplow 36 is always in contact with the ground. The pressure strips 35 on the upper and lower sides of the arc groove plate 33 are in contact with the outer side of the rotating plate 34 to achieve radial limiting and prevent the rotating plate 34 from slipping or shifting. The elastic inner pad 38 between the pressure strip 35 and the rotating plate 34 can be elastically deformed under pressure when the rotating plate 34 slides and is impacted by the ground, buffering vibration and impact force and reducing wear.

[0023] In the buffer mechanism 4, the connecting shaft plate 41 at the center of the support plate 12 is rotatably mounted with the fixed groove plate 42 via the shaft, and the fixed groove plate 42 is fixedly connected to the snowplow 31, so that the entire snowplow mechanism 3 can rotate slightly around the shaft, providing a structural basis for angle adjustment. Support frames 43 are symmetrically installed on both sides of the support plate 12, and the top of the fixed plate 44 inside the support frame 43 is fixed with symmetrically arranged fixed columns 46. The fixed columns 46 are slidably adapted to the column grooves of the column groove plate 48. A spring 45 is assembled between the column groove plate 48 and the fixed plate 44. During normal snow pushing, the spring 45 is in a pre-tight state to maintain the working angle of the snowplow. When encountering thick snow, hard snow, or ground protrusions that generate impact loads, the snowplow 31 is pressed and drives the connecting block 47 and the inclined plate 48. The overall displacement of panel 49 and column groove plate 48 causes column groove plate 48 to slide along fixed column 46, compressing spring 45. Through the compression deformation of spring 45, shovel mechanism 3 rotates. In conjunction with the deformation of leaf spring 24 of top support mechanism 2, shovel mechanism 3 can achieve a small backward tilt angle adjustment, buffering instantaneous impact pressure and avoiding deformation of shovel due to rigid pushing. When the impact load disappears, spring 45 elastically resets, causing shovel mechanism 3 to automatically return to the initial working angle. The top of inclined panel 49 has a central protruding inclined surface. The inclined surface of limit plate 410 on the inner side of support frame 43 fits against the bottom of inclined panel 49, limiting the maximum backward tilt angle of shovel, preventing excessive compression of spring 45, and preventing shovel swaying and deviation, ensuring the stability of angle adjustment.
