Description

Technical Field

[0001] The present invention is a snow plow device, belonging to the technical field of snow plows. Background Art

[0002] The main use of a snow plow is for snow removal operations on winter roads, especially in the north or cold regions, to help clear snow or ice on the road surface and ensure travel safety. Such snow plows are mostly installed on multi-functional integrated vehicles such as sprinkler trucks and road sweepers, and a quick connection device between the snow plow and the chassis is used to achieve convenient installation and disassembly. Moreover, the power source is from the original vehicle power supply, making its operation more efficient. At the same time, the snow plow can be matched with various vehicle models and has strong adaptability.

[0003] In the prior art, the chassis connection seat of the snow plow usually realizes the up-and-down flipping action through triangular frame welding and hinging. However, due to differences in road conditions, the front and rear ground clearances of the chassis connection seat are inconsistent, resulting in difficult progress of the snow plow. When the chassis connection seat is at a high ground clearance, the blade and steering mechanism of the snow plow are prone to tilting forward, and when the chassis is at a low ground clearance, it will cause obstacles to progress.

[0004] Since the snow covers and it is impossible to judge whether there are unevenness on the road surface, and the existing snow plows have inconsistent chassis ground clearances. During the working process, combined with differences in road conditions, the snow plow does not make full contact with the ground, and it is easy to have missed areas during the snow shoveling work. Moreover, due to different road widths, the snow plow mostly needs to repeat the operation to completely remove the snow, increasing the workload.

[0005] Therefore, the purpose of this research is to design a snow plow that can timely and accurately adjust and maintain the chassis ground clearance during the traveling work process, the snow plow can adapt to different road condition differences, and a device that can adjust the width of the snow plow according to the road width. Summary of the Invention

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a snow plow device to solve the problems of the prior art.

[0007] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0008] A snow plow device includes: a front fixing frame fixedly connected to the vehicle chassis, a connection seat slidably installed on the front fixing frame, and a first driving component for driving the connection seat to move left / right on the front fixing frame;

[0009] On the side of the connection seat away from the front fixing frame, there is an installation bracket, a set of connecting rod components rotatably installed between the installation bracket and the connection seat, a second driving component for driving the installation bracket to rotate up / down, and a pressure monitoring component arranged at the installation position of the connecting rod components;

[0010] A tripod is rotatably installed below the side of the mounting bracket away from the connecting seat, and a third driving component is provided to drive the adjustment of the included angle between the tripod and the mounting bracket;

[0011] One end of the tripod away from the mounting bracket is rotatably installed with a snow plow, and a fourth driving component is provided on both sides of the mounting bracket to drive the snow plow to swing left / right with the area of the mounting bracket as the axis;

[0012] The snow plow includes a main snow plow rotatably connected to the mounting bracket, auxiliary snow plows slidably installed on both sides of the main snow plow, and a fifth driving component to drive the two auxiliary snow plows to expand / retract from both sides of the main snow plow;

[0013] A first visual monitoring component is provided above the main snow plow to monitor the snow accumulation height in the snow plow, and a second visual monitoring component is provided above the auxiliary snow plow to monitor obstacles on both sides of the road;

[0014] A control module, the control module is electrically connected to the first driving component, the second driving component, the third driving component, the fourth driving component, the fifth driving component, the first visual monitoring component, the second visual monitoring component, and the pressure monitoring component;

[0015] The control module controls the third driving component to drive the tripod to rotate around the connecting part with the mounting bracket, and adjust the lower part of the snow plow to abut against the ground;

[0016] The pressure monitoring component monitors the pressure at the installation part of the link component. When the snow plow is blocked, the pressure on the link component increases, and the control module cooperates to control the second driving component to drive the mounting bracket to rotate upward;

[0017] The pressure monitoring component monitors the pressure at the installation part of the link component. When the snow plow is suspended, the pressure on the link component decreases, and the control module cooperates to control the second driving component to drive the mounting bracket to rotate downward to keep the snow plow in a state of being in contact with the ground;

[0018] When the snow accumulation height in the snow plow reaches the preset height monitored by the second visual monitoring component, the left / right direction without obstacles is determined by the first visual monitoring component, and the control module cooperates to control the fourth driving component to drive the snow plow to swing left / right and push the snow to the left / right direction without obstacles;

[0019] Monitor obstacles through the first visual monitoring component, measure the width of the road surface that needs to be shoveled, and cooperate with the control module to control the fifth drive component to drive the secondary snowboard to expand from both sides of the main snowboard to the corresponding width of the road surface that needs to be shoveled.

[0020] If the width on one side is insufficient, the control module controls the first drive component to drive the connecting seat to move left / right to adjust the length of one side of the snow shovel.

[0021] As a further improvement, the first drive component includes a group of first motors fixedly installed on the connecting seat, a gear fixedly installed at the output end of the first motor, and a sliding block welded on the connecting seat towards the direction of the gear. A strip groove is provided on the sliding block, and the first motor is electrically connected to the control module;

[0022] A guiding rod and a rack parallel to the guiding rod are fixedly installed on the front fixing frame;

[0023] The gear meshes with the rack. The sliding block is slidably installed on the guiding rod through the strip groove. By driving the gear to rotate forward / backward by the first motor, and cooperating with the guiding rod and the sliding block for guiding, the connecting seat is driven to move left / right on the rack to perform a lateral compensation of ±30 cm.

[0024] As a further improvement, the second drive component includes a first hydraulic telescopic cylinder fixedly installed in the middle below the connecting seat. The output end of the first hydraulic telescopic cylinder is rotatably installed in the middle of the installation bracket through a pin shaft. By extending / retracting the telescopic rod of the first hydraulic telescopic cylinder, the installation bracket is pushed to rotate up / down around the installation area with the connecting seat.

[0025] As a further improvement, the third drive component includes a second motor rotatably installed on one side above the installation bracket through a pin shaft, an external threaded rotating rod inserted into the output end of the second motor, and an internal threaded tube rotatably installed on the triangular frame through a pin shaft;

[0026] The second motor is electrically connected to the control module. The control module controls the second motor to drive the external threaded rotating rod to rotate forward / backward. By adjusting the length of the external threaded rotating rod inserted into the internal threaded tube, the included angle between the triangular frame and the installation bracket is further adjusted.

[0027] As a further improvement, a group of guide grooves are horizontally arranged on one side of the main snowboard away from the triangular frame, and guide strips are provided on one side of the secondary snowboard facing the main snowboard corresponding to the height of the guide grooves. The guide strips are slidably inserted into the interior of the guide grooves.

[0028] As a further improvement, the width of the open side of the guide groove is smaller than the width of the closed side at the bottom, and the guide bar is adapted to the guide groove.

[0029] As a further improvement, the fourth drive assembly includes a set of third hydraulic telescopic cylinders rotatably installed on both sides of the tripod. The output end of the third hydraulic telescopic cylinder is fixedly installed on the main snowboard. By synchronously controlling the control module, the telescopic rod in one of the third hydraulic telescopic cylinders extends, and the telescopic rod in the other third hydraulic telescopic cylinder retracts, pushing the main snowboard to tilt 30°-60° towards one side.

[0030] As a further improvement, the fifth drive assembly includes a set of second hydraulic telescopic cylinders installed on the back of the main snowboard. The output end of the second hydraulic telescopic cylinder is fixedly installed on the back of the secondary snowboard. By controlling the telescopic rod in the second hydraulic telescopic cylinder to extend / retract through the control module, the secondary snowboard is pushed to expand / retract laterally, and an electric telescopic adjustment in the range of 0.5 m - 3.2 m is performed.

[0031] As a further improvement, the first visual monitoring assembly is installed at the outer edge position above the secondary snowboard. The first visual monitoring assembly includes a biological monitoring sensor and a non-biological monitoring sensor. The biological monitoring sensor and the non-biological monitoring sensor are electrically connected to the control module;

[0032] Pedestrians and animals are detected by the biological monitoring sensor, and obstacles are monitored by the non-biological monitoring sensor.

[0033] As a further improvement, the second visual monitoring assembly is vertically installed on the outer side above the main snowboard. The height of the snow accumulation is judged by monitoring the remaining visible area of the main snowboard. The second visual monitoring assembly uses a TOF depth camera.

[0034] As a further improvement, the link assembly includes a set of support rods and a connecting rod connecting the two support rods. Through holes are provided at both ends of the support rods. The two ends of the support rods are respectively rotatably installed on the connecting seat and the mounting support through pins inserted into the through holes;

[0035] The pressure monitoring assembly includes a pressure sensor, and the pressure sensor is embedded and installed above the interior of the through hole.

[0036] The beneficial effects of the present invention are:

[0037] The present invention improves terrain adaptation control by setting the first technical layer, improves snow accumulation processing control by the second technical layer, and improves working area control by the third technical layer, specifically as follows:

[0038] Since the contact state between the snowplow blade and the ground during snow removal operations directly affects the ice-breaking efficiency, when the snowplow blade is excessively pressed down or suspended due to uneven road surfaces, it will cause abnormal wear of the ice-breaking bars or ice-breaking failure.

[0039] Three-axis linkage adjustment system is used to achieve three-dimensional dynamic compensation. First, the third drive component drives the tripod for pitch angle adjustment to establish a basic contact surface; then, the load change of the connecting rod component is monitored in real time through a pressure sensor: when the pressure value exceeds the safety threshold (suspended state), the second drive component immediately lifts the mounting bracket to form a buffer gap of 0.5 - 2 cm; when the pressure value is lower than the working threshold (obstructed state), it drives in the reverse direction to make the snowplow blade resume contact with the ground, forming a closed-loop control circuit.

[0040] During the operation of the snowplow, when the snow accumulation on the snowplow blade exceeds the limit, it will cause equipment overload, and the traditional fixed snow-throwing direction is likely to cause secondary accumulation.

[0041] By constructing and arranging a group of first visual monitoring components to form a binocular vision collaborative decision-making mechanism. The second visual monitoring component uses a TOF depth camera to monitor the snow height in real time. When it reaches the preset threshold (usually set to 80% of the bucket capacity), the first visual monitoring component detects obstacles within a range of 5 meters through stereo vision algorithms. After the path planning module calculates the optimal snow-throwing direction, finally, the fourth drive component performs directional swinging snow-throwing within the range of 30° - 60°, and the response time of this process is controlled within 500 ms.

[0042] In addition, during operation on complex road conditions, the effective working width changes dynamically, and traditional fixed snowplow blades are difficult to adapt to diverse snow-clearing requirements.

[0043] Flexible expansion is achieved through three-level width adjustment. The control module calculates the available working road width in real time through binocular ranging of the first visual monitoring component, and the fifth drive component drives the auxiliary snowplow blade for electric telescopic adjustment within the range of 0.5 meters - 3.2 meters; when the unilateral expansion margin is insufficient, the first drive component starts the first motor to make the entire snowplow unit perform lateral compensation of ±30 cm on the guide rail.

[0044] Through the above improvements, various complex road conditions can be dealt with during the working process, and the snowplowing amplitude can be adaptively adjusted according to the road width and road obstacles. Through multi-level adjustment, the omission area can be avoided as much as possible, and due to the high road adaptability, repeated operations are avoided, reducing the workload.

[0057] Refer to Figure 1-8 As shown, a snow plow device includes:

[0058] A front fixing frame 1 fixedly connected to the vehicle chassis, a connecting seat 2 slidably mounted on the front fixing frame 1, and a first driving assembly 21 for driving the connecting seat 2 to move left / right on the front fixing frame 1;

[0059] On the side of the connecting seat 2 away from the front fixing frame 1, there is an installation bracket 3, a set of connecting rod assemblies 4 rotatably mounted between the installation bracket 3 and the connecting seat 2, a second driving assembly 41 for driving the installation bracket 3 to rotate up / down, and a pressure monitoring assembly 42 provided at the installation part of the connecting rod assemblies 4;

[0060] A tripod 5 is rotatably mounted below the side of the installation bracket 3 away from the connecting seat 2, and a third driving assembly 51 for driving the angle adjustment between the tripod 5 and the installation bracket 3;

[0061] One end of the tripod 5 away from the installation bracket 3 is rotatably mounted with a snow plow board 6, and fourth driving assemblies 61 are provided on both sides of the installation bracket 3 for driving the snow plow board 6 to swing left / right with the area of the installation bracket 3 as the axis;

[0062] The snow plow 6 includes a main snow plow 62 rotatably connected to the mounting bracket 3, secondary snow plows 63 slidably mounted on both sides of the main snow plow 62, and a fifth drive assembly 64 for driving the two secondary snow plows 63 to expand / retract from both sides of the main snow plow 62;

[0063] A first visual monitoring assembly 65 for monitoring the snow accumulation height inside the snow plow 6 is provided above the main snow plow 62, and a second visual monitoring assembly 66 for monitoring obstacles on both sides of the road is provided above the secondary snow plows 63;

[0064] A control module 7, the control module 7 is electrically connected to the first drive assembly 21, the second drive assembly 41, the third drive assembly 51, the fourth drive assembly 61, the fifth drive assembly 64, the first visual monitoring assembly 65, the second visual monitoring assembly 66, and the pressure monitoring assembly 42;

[0065] By controlling the third drive assembly 51 through the control module 7, driving the tripod 5 to rotate around the connection part with the mounting bracket, and adjusting the snow plow 6 to abut against the ground below;

[0066] By monitoring the pressure at the installation site of the link assembly 4 through the pressure monitoring assembly 42, when the snow plow 6 is blocked, the pressure on the link assembly 4 increases, and in cooperation with the control module 7, controlling the second drive assembly 41 to drive the mounting bracket 3 to rotate upward;

[0067] By monitoring the pressure at the installation site of the link assembly 4 through the pressure monitoring assembly 42, when the snow plow 6 is suspended, the pressure on the link assembly 4 decreases, and in cooperation with the control module 7, controlling the second drive assembly 41 to drive the mounting bracket 3 to rotate downward to keep the snow plow 6 in a state of being in contact with the ground;

[0068] When the snow accumulation height inside the snow plow 6 reaches the preset height monitored by the second visual monitoring assembly, determining the left / right direction without obstacles through the first visual monitoring assembly 65, and in cooperation with the control module 7, controlling the fourth drive assembly 61 to drive the snow plow 6 to swing left / right to push the snow to the left / right direction without obstacles;

[0069] By monitoring obstacles through the first visual monitoring assembly 65 and measuring the road surface width that needs to be plowed, and in cooperation with the control module 7, controlling the fifth drive assembly 64 to drive the secondary snow plows 63 to expand from both sides of the main snow plow 62 to correspond to the road surface width that needs to be plowed;

[0070] When the width of one side is insufficient, by controlling the first drive assembly 21 through the control module 7, driving the connection seat 2 to move left / right to adjust the length of one side of the snow plow 6.

[0071] The front and rear ground clearances of the chassis connecting seat 2 of the existing snow plow are inconsistent, resulting in insufficient snow shoveling work, especially on uneven ground. To solve this problem, the second drive assembly 41 drives the up and down rotation of the mounting bracket 3, and the pressure monitoring assembly 42 monitors the downward pressure of the snow plow 6, enabling precise adjustment of the contact state between the snow plow 6 and the ground. When the snow plow 6 encounters an obstruction, the pressure increases, and the system automatically adjusts the mounting bracket 3 upward through the second drive assembly 41 to keep the snow plow 6 in contact with the ground; when the snow plow 6 is suspended, the pressure decreases, and the system will automatically adjust downward to ensure that the snow plow 6 can always closely adhere to the ground for efficient snow shoveling operations.

[0072] Through the cooperation of the tripod 5 and the second drive assembly 41, the angle of the snow plow 6 can be adjusted according to the ground conditions, ensuring that the snow plow 6 can maintain a good contact state under various complex terrains, thereby improving work efficiency and avoiding missing snow layers.

[0073] To adapt to different road widths, the deployment / retraction function of the auxiliary snow plow 63 and the main snow plow 62 is designed. The fifth drive assembly 64 controls the deployment and contraction of the auxiliary snow plow 63, thereby achieving adaptation to road surfaces of different widths. In addition, by driving the connecting seat 2 to move left / right through the first drive assembly 21, the length of one side of the snow plow 6 can be flexibly adjusted to ensure that snow shoveling operations can accurately cover different road surface conditions.

[0074] Through the first vision monitoring assembly 65 and the second vision monitoring assembly 66, the snow accumulation height inside the snow plow 6 and the obstacles on both sides of the road surface can be monitored in real time, ensuring that snow shoveling operations can be carried out in obstacle-free areas. When the snow accumulation height reaches the preset value, the snow plow 6 can automatically swing left / right to push the snow to the obstacle-free side, improving work efficiency and coverage.

[0075] It also includes moving wheels 8 rotatably mounted on both sides under the snow plow board. When encountering a sloping ground or other situations, the moving wheels 8 can be adjusted to abut against the ground to assist in moving. A spring assembly 9 is fixedly installed between the back of the snow plow 6 and the tripod 5 or the fourth drive assembly 61, which can play a role in damping the snow plow 6.

[0076] Compared with the prior art, it is usually difficult for the ground clearance of the chassis connecting seat 2 of the existing snow plow equipment to adapt to complex road conditions, and when the road surface is uneven, it is easy to have poor contact between the snow plow 6 and the ground, resulting in poor snow shoveling effect, and even the situation of the snow plow 6 tilting or being unable to effectively advance.

[0077] The contact pressure between the snowplow blade 6 and the ground is monitored in real time by the pressure monitoring component 42, and the up-and-down position of the mounting bracket 3 is accurately adjusted by the second drive component 41, so that the height of the snowplow blade 6 can be automatically adjusted according to the ground conditions, ensuring that the snowplow blade 6 is always in full contact with the ground and avoiding unsmooth operation caused by inconsistent ground clearance.

[0078] Most existing snowplows achieve the flipping of the snowplow blade 6 through a fixed tripod 5 and a hinge device, but their adaptability to complex road conditions and different terrains is limited, which is likely to cause difficulties in traveling.

[0079] Through the coordinated work of the tripod 5 and the second drive component 41, the angle of the snowplow blade 6 can be adjusted to adapt to different road surfaces and obstacles. This adaptive function can effectively cope with different terrains, such as uneven roads, ensuring that the contact state of the snowplow blade 6 is always optimal, thereby improving the operation efficiency.

[0080] Most snowplow equipment has poor adaptability to road widths. It often needs to repeat operations to completely remove snow, and it cannot flexibly adjust the width of the snowplow blade 6 according to roads of different widths.

[0081] By driving the expansion and retraction of the auxiliary snowplow blade 63 by the fifth drive component 64, the working width of the snowplow blade 6 can be automatically adjusted according to different road widths, thus avoiding repeated operations, reducing the workload, and being able to accurately cover roads of different widths.

[0082] To accurately control the left-right movement of the connecting seat 2, the first drive component 21 includes a set of first motors 211 fixedly installed on the connecting seat 2, a gear 212 fixedly installed at the output end of the first motor 211, and a sliding block 213 welded on the connecting seat 2 in the direction towards the gear 212. A strip groove 214 is provided on the sliding block 213, and the first motor 211 is electrically connected to the control module 7;

[0083] A guide rod 215 and a rack 216 parallel to the guide rod 215 are fixedly installed on the front fixing frame 1;

[0084] The gear 212 meshes with the rack 216, and the sliding block 213 is slidably installed on the guide rod 215 through the strip groove 214. By driving the gear 212 to rotate forward / backward by the first motor 211, and cooperating with the guiding of the guide rod 215 and the sliding block 213, the connecting seat 2 is driven to move left / right on the rack 216. In this embodiment, a lateral compensation of ±30 cm can be performed.

[0085] By setting up the combination of the first motor 211, gear 212, rack 216, guide rod 215 and slider 213, the connecting seat 2 can be accurately moved left and right in the horizontal direction. This precise movement control is to flexibly adjust the working width or position of the snow plow 6 according to the ground conditions, so as to ensure the efficiency and accuracy of the snow removal operation. It enables the snow plow to make dynamic adjustments according to different road widths, snow thicknesses and obstacles. For example, when facing a narrow road surface, the connecting seat 2 can move to one side to reduce the width of the snow plow 6 and avoid unnecessary operations and losses. On the contrary, on a wide road, the width of the connecting seat 2 can be adjusted to ensure a more efficient operation coverage.

[0086] Among them, the combination of the guide rod 215 and the slider 213 can stabilize the sliding track of the snow plow 6 and ensure that the left and right movement of the connecting seat 2 is not affected by uneven pressure or external interference. The slider 213 slides in the strip groove 214 of the guide rod 215, avoiding uncontrolled deviation. It can prevent the snow plow 6 from tilting or losing balance due to uneven ground or uneven pressure, and maintain the stability and accuracy of the operation. In addition, the sliding of the slider 213 in the strip groove 214 can ensure the smooth movement of the snow plow during operation, reduce wear and extend the service life of the equipment.

[0087] To adapt to complex terrains and improve operation efficiency, the meshing design of the gear 212 and the rack 216 is combined, making the transmission process smoother and the torque transmission more efficient, and being able to adapt to complex terrain changes. This system not only ensures the stable operation of the snow plow on uneven road surfaces, but also can better cope with complex conditions such as obstacles. It can improve the adaptability of the equipment, automatically adjust the width and position of the snow plow 6 when facing different road conditions, and ensure the continuity and efficiency of the snow removal operation. Especially in urban areas or more complex environments, it can significantly improve the coverage and accuracy of road cleaning.

[0088] The slider 213 and the guide rod 215 are guided through the strip groove 214, effectively reducing the relative friction between components. At the same time, the meshing transmission method of the gear 212 and the rack 216 is more stable, reducing excessive mechanical shock.

[0089] To realize the up and down adjustment of the mounting bracket 3, the second driving component 41 includes a first hydraulic telescopic cylinder 411 fixedly installed in the middle below the connecting seat 2. The output end of the first hydraulic telescopic cylinder 411 is rotationally installed in the middle of the mounting bracket 3 through a pin shaft. By extending / retracting the telescopic rod of the first hydraulic telescopic cylinder 411, the mounting bracket 3 is pushed to rotate up / down around the installation area with the connecting seat 2.

[0090] By setting the first hydraulic telescopic cylinder 411 and connecting its output end to the mounting bracket 3, the up-and-down adjustment of the mounting bracket 3 can be achieved through the telescopic action of the cylinder. The telescopic rod of the cylinder extends or retracts, thereby driving the mounting bracket 3 to rotate around the mounting area of the connecting seat 2 to adjust the height of the snow plow. The snow plow is allowed to adjust the height of the snow plow blade 6 according to the actual road conditions, so that it can adapt to different snow layer thicknesses and ground conditions. For example, when the snow accumulation is thick, the mounting bracket 3 can be adjusted to a higher position to avoid jamming or damage caused by the too low snow plow blade 6; when the road surface is relatively flat or the snow accumulation is thin, the height of the snow plow blade 6 can be reduced to improve the snow plowing effect.

[0091] By adding the first hydraulic telescopic cylinder 411 to the second drive assembly 41, the precise up-and-down adjustment of the mounting bracket 3 is realized, which can improve the adaptability, stability and safety of the snow plow under different ground conditions. This design not only enhances the flexibility and efficiency of the equipment, but also improves the operation accuracy, reduces the manual intervention and increases the degree of automation.

[0092] To achieve precise angle adjustment, the third drive assembly 51 includes a second motor 511 rotatably mounted above one side of the mounting bracket 3 through a pin shaft, an external thread rotating rod 512 inserted at the output end of the second motor 511, and an internal thread tube 513 rotatably mounted on the tripod 5 through a pin shaft;

[0093] The second motor 511 is electrically connected to the control module 7. The control module 7 is used to control the second motor 511 to drive the external thread rotating rod 512 to rotate forward / backward. By adjusting the length of the external thread rotating rod 512 inserted into the internal thread tube 513, the angle between the tripod 5 and the mounting bracket 3 is adjusted.

[0094] By driving the external thread rotating rod 512 to rotate forward and backward by the motor, the relative movement between the external thread rotating rod 512 and the internal thread tube 513 can adjust the angle between the tripod 5 and the mounting bracket 3. The forward and backward rotation control of the motor provides a very precise adjustment ability. The angle adjustment can be precisely controlled according to actual needs, so as to optimize the operation angle and improve the working effect. For example, adjusting the angle helps to change the angle and operation range of the snow plow, making it perform better in different operation environments and improving the snow plowing efficiency and accuracy.

[0095] The second motor 511 is used to drive the external thread rotating rod 512 for angle adjustment instead of the traditional manual adjustment method. The motor can be precisely controlled by the control module 7, making the adjustment process more stable and efficient.

[0096] To achieve the lateral adjustment of the main snowboard 62 and the auxiliary snowboard 63, a set of guide grooves 621 are horizontally arranged on the side of the main snowboard 62 away from the tripod 5, and guide bars 622 are arranged on the side of the auxiliary snowboard 63 facing the main snowboard 62 corresponding to the height of the guide grooves 621. The guide bars 622 are slidably inserted into the interior of the guide grooves 621.

[0097] The width of the open side of the guide groove 621 is smaller than the width of the closed side at the bottom, and the guide bar 622 is adapted to the guide groove 621.

[0098] To prevent the snow plow from being overloaded due to excessive accumulation of snow on the snow plow blade 6 during travel, the traditional fixed snow throwing direction is likely to cause secondary accumulation.

[0099] The fourth drive assembly 61 includes a set of third hydraulic telescopic cylinders 611 rotatably installed on both sides of the tripod 5. The output end of the third hydraulic telescopic cylinder 611 is fixedly installed on the main snowboard 62. By synchronously controlling the control module 7 to extend the telescopic rod in one of the third hydraulic telescopic cylinders 611 and retract the telescopic rod in the other third hydraulic telescopic cylinder 611, the main snowboard 62 is pushed to tilt 30° - 60° towards one side.

[0100] By cooperating with the first visual monitoring component 65 and the second visual monitoring component 66, in specific states, such as when the snow accumulation in the snow plow blade 6 exceeds 80% or there are unavoidable obstacles, etc., the telescopic rod in one of the third hydraulic telescopic cylinders 611 is extended, and the telescopic rod in the other third hydraulic telescopic cylinder 611 is retracted, pushing the main snowboard 62 to tilt 30° - 60° towards one side.

[0101] The fifth drive assembly 64 includes a set of second hydraulic telescopic cylinders 641 installed on the back of the main snowboard 62. The output end of the second hydraulic telescopic cylinder 641 is fixedly installed on the back of the auxiliary snowboard 63. By controlling the control module 7 to extend / retract the telescopic rod in the second hydraulic telescopic cylinder 641, the auxiliary snowboard 63 is pushed to laterally expand / retract. In this embodiment, electric telescopic adjustment in the range of 0.5 m - 3.2 m can be performed.

[0102] Through the design of the guide grooves 621 and the guide bars 622, the auxiliary snowboard 63 can be laterally slidably adjusted on the main snowboard 62. The guide grooves 621 are provided with openings of different widths to ensure that the guide bars 622 can slide stably therein, thereby adjusting the position of the auxiliary snowboard 63 when needed. The auxiliary snowboard 63 can be flexibly adjusted to adapt to different snow conditions and operation requirements. For example, on a wider snow track, the auxiliary snowboard 63 can be extended to provide a larger coverage area, while in a narrow space, it can be retracted to save space, improving the flexibility and efficiency of the snow plow operation.

[0103] By designing the width of the open side of the guide groove 621 to be smaller than that of the closed bottom side, the guide bar 622 and the guide groove 621 are designed such that the movement process of the secondary snowboard 63 is smoother and restricted by the structure of the guide groove 621. The structural design of the guide groove 621 can effectively control the movement range of the secondary snowboard 63, avoiding excessive or unstable lateral movement of the secondary snowboard 63. It ensures the stability of the secondary snowboard 63 during movement, avoids accidents or improper operations caused by the secondary snowboard 63 sliding too fast or too slow, and improves the accuracy and safety of the operation. In addition, it ensures that both the retraction and deployment of the secondary snowboard 63 can be carried out within a predetermined range, avoiding damage to the equipment or affecting the operation effect.

[0104] Among them, the lateral deployment and retraction of the secondary snowboard 63 are controlled by the second hydraulic telescopic cylinder 641. The hydraulic telescopic cylinder can adjust the deployment angle or retraction state of the secondary snowboard 63 according to the instructions of the control module 7. This cylinder system can provide a wide range of forces and precise control. It can flexibly respond to different snow layer conditions and operating environments. For example, when encountering heavy snow accumulation or a wide operating area, the secondary snowboard 63 can be deployed to increase the snow pushing area and improve the operation efficiency; while in a narrow space or a thin snow layer area, the secondary snowboard 63 can be retracted to reduce the occupation of the operating area and ensure the mobility of the equipment.

[0105] Through the design of the guide groove 621 and the guide bar 622 combined with the control of the second hydraulic telescopic cylinder 641, the secondary snowboard 63 can be flexibly deployed and retracted. It not only improves the adaptability and efficiency of the equipment, but also improves the stability and safety of the operation through automation and precise control. The flexible adjustment function of the secondary snowboard 63 enables the equipment to quickly respond to changes in different operating environments, greatly improving the work efficiency and operation quality.

[0106] As a further improvement, the first visual monitoring component 65 is installed at the outer edge position above the secondary snowboard 63. The first visual monitoring component 65 includes a biological monitoring sensor and a non-biological monitoring sensor. The biological monitoring sensor and the non-biological monitoring sensor are electrically connected to the control module 7;

[0107] The biological monitoring sensor is used to detect pedestrians and animals, and the non-biological monitoring sensor is used to monitor obstacles. The second visual monitoring component 66 is vertically installed on the outer side surface above the main snowboard 62, and the snow accumulation height is judged by monitoring the remaining visible area of the main snowboard 62.

[0108] Among them, the biological monitoring sensor, this kind of sensor is mainly used to identify the presence of organisms, usually including thermal imaging sensors, infrared sensors, ultrasonic sensors, etc. They can detect the body temperature of people, the movement or sound of animals, and are mainly used to monitor pedestrians and animals.

[0109] For example, a thermal imaging sensor can monitor organisms with a temperature different from the environment. If there is a pedestrian on the left side, the sensor will detect the heat of the pedestrian and determine their position and movement.

[0110] Rather than a biological monitoring sensor, this kind of sensor is used to detect non-biological obstacles, such as stones, branches, roadblocks, etc. Common technologies include lidar, ultrasonic sensors, infrared sensors, etc. These sensors can scan objects in the environment and determine their shape and distance.

[0111] For example, lidar can construct a three-dimensional map of surrounding obstacles by emitting laser beams and receiving their reflected signals, determine whether there are obstacles, and can measure the distance.

[0112] Set the monitoring logic and application scenario. When there is someone on the left side, when the biological monitoring sensor (such as an infrared sensor) on the left side detects a change in the heat of an organism, the control module 7 will recognize the appearance of a pedestrian or an animal on the left side.

[0113] According to the preset safety logic, the control module 7 can trigger an alarm or automatically decelerate, adjust the working range of the left-side secondary snowboard 63, and avoid colliding with pedestrians or animals.

[0114] When there is someone on the right side, when the biological monitoring sensor (such as an infrared sensor) on the right side detects a change in the heat of an organism, the control module 7 will recognize the appearance of a pedestrian or an animal on the left side.

[0115] According to the preset safety logic, the control module 7 can trigger an alarm or automatically decelerate, adjust the working range of the right-side secondary snowboard 63, and avoid colliding with pedestrians or animals.

[0116] When there is a non-human obstacle (such as a stone or a branch) on the left side, the non-biological monitoring sensor (such as lidar or ultrasonic sensor) will detect the presence of an obstacle in front or on the left side. When the obstacle enters the detection range, the sensor will measure the distance and shape of the object. The control module 7 will judge the type and distance of the obstacle, and then cooperate with the fifth drive component 64 to retract the secondary snowboard 63. When the obstacle is unavoidable, cooperate with the fourth drive component 61 to control the snowplow 6 to tilt towards the side without obstacles, thereby avoiding the obstacle.

[0117] When the sensors detect a pedestrian on the left side and an obstacle on the right side at the same time, the biological monitoring sensor and the non-biological monitoring sensor will provide information simultaneously.

[0118] According to the designed priority, the safety of humans is given priority. For example, assuming that the pedestrian on the left side has a higher priority, then the system may immediately take measures (such as decelerating or adjusting the secondary snowboard 63) to avoid the pedestrian.

[0119] If the obstacle on the right side is unavoidable (such as a large rock), the system can avoid threatening pedestrians and colliding with the obstacle by means of decelerating, stopping, or adjusting the operation trajectory, etc.

[0120] The second visual monitoring component 66 (such as a lidar or a vision sensor) is installed above the main snowboard 62 to vertically monitor the snow height in front of the main snowboard 62. The sensor determines the snow thickness by scanning the ground. The control module 7 automatically adjusts the deployment angle or retraction state of the auxiliary snowboard 63 by analyzing the snow height. If the snow is thick, the auxiliary snowboard 63 can be deployed to provide a larger snow-pushing area; if the snow is thin, the auxiliary snowboard 63 can be retracted to avoid wasting operation force.

[0121] For improving the structural stability and strength, the link assembly 4 includes a group of support rods 43 and a strut 44 connecting the two support rods 43. Through holes 45 are provided at both ends of the support rod 43, and both ends of the support rod 43 are respectively rotatably installed on the connection seat 2 and the mounting support by inserting a pin shaft into the through holes 45;

[0122] The pressure monitoring component 42 includes a pressure sensor 46, and the pressure sensor 46 is embedded and installed above the interior of the through hole 45.

[0123] By providing through holes 45 at both ends of the support rod 43 and rotatably connecting with the connection seat 2 and the mounting support through a pin shaft, a firm structure is formed. The rotational connection mode of the pin shaft can ensure that the support rod 43 is not easily detached or loosened during movement, and at the same time can provide sufficient supporting force to ensure the overall stability of the equipment.

[0124] Such a setting can effectively disperse the load and stress. Especially when the equipment bears a large external force or vibration, the risk of damage can be reduced, and the durability and reliability of the system can be improved.

[0125] And by installing both ends of the support rod 43 on the connection seat 2 and the mounting support respectively through a pin shaft, not only is the structure simple, but also the later installation and disassembly are convenient. The user can easily install or disassemble the support rod 43, and no complex tools or large-scale disassembly are required during the maintenance process.

[0126] In addition, all the rotational connections in this solution are made by pin shafts.

[0127] The pressure sensor 46 is embedded and installed above the interior of the through hole 45, which can accurately monitor the pressure change in the through hole 45. Since the position of the sensor is close to the stress point, it can reflect the pressure borne by the connecting components in real time, thus ensuring the effective monitoring of the equipment pressure.

[0128] The load change of the connecting rod assembly 4 is monitored in real time by the pressure sensor 46: when the pressure value exceeds the safety threshold (hanging state), the second driving assembly 41 immediately lifts the mounting bracket 3 to form a buffer gap of 0.5 - 2 cm; when the pressure value is lower than the working threshold (obstructed state), it is driven in the reverse direction to make the snowplow 6 resume ground contact, forming a closed-loop control circuit.

[0129] When the snowplow 6 is obstructed, the protruding part of the mounting support inserted inside the through hole 45 exerts force on the opposite side of the through hole 45 where the pressure sensor 46 is installed, so the pressure received by the pressure sensor 46 decreases;

[0130] When the snowplow 6 is hanging, the protruding part of the mounting support inserted inside the through hole 45 exerts force on the same side of the through hole 45 where the pressure sensor 46 is installed, so the pressure received by the pressure sensor 46 increases.
