Description

Technical Field

[0001] The invention relates to a snow shovel device, belonging to the technical field of snow shovels. Background Art

[0002] The main purpose of a snowplow is to remove snow from roads in winter, especially in northern or cold regions, to help clear snow or ice on the road and ensure travel safety. This type of snowplow is mostly installed on multifunctional vehicles such as sprinklers and road sweepers. The snowplow and chassis are connected by a quick connection device to achieve convenient installation and removal, and the power comes from the original vehicle power supply, making its operation more efficient. At the same time, the snowplow can be matched with a variety of vehicle models and has strong adaptability.

[0003] In the prior art, the chassis connection seat of the snowplow is usually welded and hinged by a tripod to achieve the up and down flipping action. However, due to different road conditions, the front and rear heights of the chassis connection seat are inconsistent, which makes it difficult for the snowplow to move. When the chassis connection seat is higher from the ground, the shovel blade and steering mechanism of the snowplow are prone to tilt forward, and when the chassis is lower from the ground, it will cause the movement to be blocked.

[0004] Because the snow covers the road, it is impossible to tell whether there are bumps on the road surface. The existing snowplows have chassis at different heights from the ground. Coupled with differences in road conditions during operation, the snowplows do not have sufficient contact with the ground, making the snowplows too heavy to work on and easily miss areas. In addition, due to the different road widths, snowplows often need to repeat operations to completely clear the snow, increasing the workload.

[0005] Therefore, the purpose of this study is to design a snowplow that can accurately adjust the height of the chassis off the ground in a timely manner during operation, a snowplow that can adapt to different road conditions, and a device that can adjust the width of the snowplow according to the width of the road. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a snow shovel device to solve the problems of the prior art.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions: A snow shovel device comprises: a front fixing frame fixedly connected to a vehicle chassis, a connecting seat slidably mounted on the front fixing frame, and a first driving assembly driving the connecting seat to move leftward / rightward on the front fixing frame; A mounting bracket, a group of connecting rod assemblies rotatably mounted between the mounting bracket and the connecting bracket, a second driving assembly driving the mounting bracket to rotate upward / downward, and a pressure monitoring assembly arranged at the mounting position of the connecting rod assembly are provided on the side of the connecting seat away from the front fixing frame; A tripod is rotatably mounted below the mounting bracket on a side away from the connecting seat, and a third driving component is driven to adjust the angle between the tripod and the mounting bracket; A fourth driving assembly is provided on one end of the tripod away from the mounting bracket and is rotatably mounted with a snow shovel, and is arranged on both sides of the mounting bracket to drive the snow shovel to swing leftward or rightward with the mounting bracket area as the axis; The snow shovel comprises a main snowboard rotatably connected to the mounting bracket, auxiliary snowboards slidably mounted on both sides of the main snowboard, and a fifth driving assembly driving the two auxiliary snowboards to be deployed / recovered from both sides of the main snowboard; A first visual monitoring component for monitoring the height of snow accumulation in the snow shovel is arranged above the main snowboard, and a second visual monitoring component for monitoring obstacles on both sides of the road is arranged above the auxiliary snowboard; A control module, wherein the control module is electrically connected to the first drive assembly, the second drive assembly, the third drive assembly, the fourth drive assembly, the fifth drive assembly, the first visual monitoring assembly, the second visual monitoring assembly, and the pressure monitoring assembly; The third driving assembly is controlled by the control module to drive the tripod to rotate around the connection portion with the mounting bracket, so as to adjust the lower side of the snow shovel to abut against the ground; The pressure monitoring component monitors the pressure of the connecting rod assembly installation part. When the snow shovel is blocked, the pressure on the connecting rod assembly increases, and the control module cooperates with the second driving component to drive the mounting bracket to rotate upward. The pressure monitoring component monitors the pressure of the connecting rod assembly installation part. When the snow shovel is suspended in the air, the pressure on the connecting rod assembly is reduced, and the control module cooperates with the second driving component to drive the mounting bracket to rotate downward to keep the snow shovel on the ground; When the height of the accumulated snow in the snow shovel reaches a preset height through the second visual monitoring component, the left / right direction without obstacles is determined through the first visual monitoring component, and the fourth driving component is controlled in cooperation with the control module to drive the snow shovel to swing to the left / right side to push the accumulated snow to the left / right direction without obstacles; The first visual monitoring component monitors obstacles, measures the width of the road surface required for snow shoveling, and cooperates with the control module to control the fifth driving component to drive the auxiliary snowboard to unfold from both sides of the main snowboard to the width of the road surface required for snow shoveling; If the width on one side is insufficient, the control module controls the first driving assembly to drive the connecting seat to move left / right to adjust the length of one side of the snow shovel.

[0008] As a further improvement, the first driving assembly includes a group of first motors fixedly mounted on the connecting seat, a gear fixedly mounted on the output end of the first motor, and a sliding block welded on the connecting seat toward the gear, a groove is provided on the sliding block, and the first motor is electrically connected to the control module; The front fixing frame is fixedly mounted with a guide rod and a rack arranged parallel to the guide rod; The gear is meshed with the rack, and the sliding block is slidably installed on the guide rod through a groove. The gear is driven by the first motor to rotate forward / reverse, and the guide rod and the sliding block are guided. The gear is meshed with the rack to drive the connecting seat to move left / right, and a lateral compensation of ±30cm is performed.

[0009] As a further improvement, the second drive assembly includes a first hydraulic telescopic cylinder fixedly installed in the middle part below the connecting seat, and the output end of the first hydraulic telescopic cylinder is rotatably installed in the middle part of the mounting bracket through a pin shaft. The telescopic rod of the first hydraulic telescopic cylinder is extended / retracted to push the mounting bracket to rotate upward / downward around the mounting area of ​​the connecting seat.

[0010] As a further improvement, the third driving assembly includes a second motor rotatably mounted on one side above the mounting bracket via a pin shaft, an externally threaded rotating rod inserted at the output end of the second motor, and an internally threaded tube rotatably mounted on the tripod via a pin shaft; The second motor is electrically connected to the control module, and the control module controls the second motor to drive the external threaded rotating rod to rotate forward / reverse. The angle between the tripod and the mounting bracket is adjusted by adjusting the length of the external threaded rotating rod inserted in the internal threaded tube.

[0011] As a further improvement, a group of guide grooves are laterally arranged on the side of the main snowboard away from the tripod, and a guide bar is arranged on the side of the auxiliary snowboard facing the main snowboard at a height corresponding to the guide groove, and the guide bar is slidably inserted inside the guide groove.

[0012] As a further improvement, the width of the open side of the guide groove is smaller than the width of the closed bottom side thereof, and the guide bar is adapted to the guide groove.

[0013] As a further improvement, the fourth drive assembly includes a group of third hydraulic telescopic cylinders rotatably mounted on both sides of the tripod, and the output ends of the third hydraulic telescopic cylinders are fixedly mounted on the main snowboard. The control module synchronously controls the extension of a telescopic rod in one of the third hydraulic telescopic cylinders and the retraction of a telescopic rod in another of the third hydraulic telescopic cylinders, thereby pushing the main snowboard to tilt 30-60° toward one side.

[0014] As a further improvement, the fifth drive assembly includes a group of second hydraulic telescopic cylinders installed on the back of the main snowboard, and the output end of the second hydraulic telescopic cylinder is fixedly installed on the back of the auxiliary snowboard. The control module controls the extension / retraction of the telescopic rod in the second hydraulic telescopic cylinder to push the auxiliary snowboard to unfold / retract laterally, and perform electric telescopic adjustment in the range of 0.5-3.2 meters.

[0015] As a further improvement, the first visual monitoring component is installed at the outer edge position above the auxiliary snowboard, and the first visual monitoring component includes a biological monitoring sensor and a non-biological monitoring sensor, and the biological monitoring sensor and the non-biological monitoring sensor are electrically connected to the control module; Pedestrians and animals are detected by the biological monitoring sensor, and obstacles are monitored by the non-biological monitoring sensor.

[0016] As a further improvement, the second visual monitoring component is vertically installed on the outer side above the main snow board, and the snow height is determined by monitoring the remaining visible area of ​​the main snow board. The second visual monitoring component adopts a TOF depth camera.

[0017] As a further improvement, the connecting rod assembly includes a group of support rods and a support rod connecting two of the support rods, both ends of the support rods are provided with through holes, and the two ends of the support rods are respectively inserted into the through holes through pins and rotatably mounted on the connecting seat and the mounting support; The pressure monitoring assembly includes a pressure sensor, and the pressure sensor is embedded and installed above the interior of the through hole.

[0018] The beneficial effects of the present invention are: The present invention improves terrain adaptation control by setting a first technical layer, improves snow processing control by a second technical layer, and improves operation area control by a third technical layer, as follows: Since the contact state between the snowplow and the ground during snow pushing operations directly affects the ice-breaking efficiency, when the snowplow is over-pressed or suspended in the air due to uneven road conditions, it will cause abnormal wear of the ice-breaking bars or ice-breaking failure.

[0019] Three-dimensional dynamic compensation is achieved through a three-axis linkage adjustment system. First, the third drive component drives the tripod to adjust the pitch angle to establish a basic contact surface; then the load change of the connecting rod component is monitored in real time through the 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 0.5-2cm; when the pressure value is lower than the working threshold (obstructed state), the reverse drive restores the snow shovel to the ground, forming a closed-loop control circuit.

[0020] While the snowplow is moving, the excessive accumulation of material on the snowplow blade will cause the equipment to overload, and the traditional fixed snow throwing direction is prone to cause secondary accumulation.

[0021] A binocular vision collaborative decision-making mechanism is formed by constructing and deploying a set of first visual monitoring components. The second visual monitoring component uses a TOF depth camera to monitor the snow height in real time. When the preset threshold (usually set to 80% of the bucket capacity) is reached, the first visual monitoring component uses a stereoscopic vision algorithm to detect obstacles within a range of 5 meters, and the path planning module calculates the optimal snow throwing direction. Finally, the fourth drive component executes directional swing snow throwing within the range of 30-60 degrees. The response time of this process is controlled within 500ms.

[0022] In addition, the effective operating width changes dynamically under complex road conditions, and traditional fixed shovels are difficult to adapt to diverse snow clearing needs.

[0023] Flexible expansion is achieved by adopting three-level width adjustment. The control module calculates the width of the workable road surface in real time through the binocular distance measurement of the first visual monitoring component, and the fifth drive component drives the auxiliary snowboard to perform electric telescopic adjustment within the range of 0.5-3.2 meters; when the expansion margin on one side is insufficient, the first drive component starts the first motor to make the entire snow shoveling unit perform ±30cm lateral compensation on the guide rail.

[0024] The above improvements can cope with various complex road conditions during the working process, and can adaptively adjust the snow shoveling range according to the road width and road obstacles. Through multi-level adjustment, missed areas can be avoided as much as possible. In addition, due to the high adaptability to the road surface, repeated operations are avoided and the workload is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Reference Figure 1-8 As shown, a snow shovel device comprises: 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 driving the connecting seat 2 to move leftward / rightward on the front fixing frame 1; A mounting bracket 3, a connecting rod assembly 4 rotatably mounted between the mounting bracket 3 and the connecting bracket 2, a second driving assembly 41 driving the mounting bracket 3 to rotate upward / downward, and a pressure monitoring assembly 42 arranged at the mounting position of the connecting rod assembly 4 are provided on the side of the connecting base 2 away from the front fixing frame 1; A tripod 5 is rotatably mounted below the mounting bracket 3 on a side away from the connecting base 2, and a third driving component 51 is driven to adjust the angle between the tripod 5 and the mounting bracket 3; A snow shovel 6 is rotatably mounted on one end of the tripod 5 away from the mounting bracket 3, and a fourth driving assembly 61 is arranged on both sides of the mounting bracket 3 to drive the snow shovel 6 to swing left / right with the mounting bracket 3 as the axis; The snow shovel 6 includes a main snowboard 62 rotatably connected to the mounting bracket 3, auxiliary snowboards 63 slidably mounted on both sides of the main snowboard 62, and a fifth driving assembly 64 driving the two auxiliary snowboards 63 to be deployed / retracted from both sides of the main snowboard 62; A first visual monitoring component 65 for monitoring the height of snow accumulation in the snow shovel 6 is disposed above the main snowboard 62, and a second visual monitoring component 66 for monitoring obstacles on both sides of the road is disposed above the auxiliary snowboard 63; A control module 7, wherein 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; The third driving assembly 51 is controlled by the control module 7 to drive the tripod 5 to rotate around the connection portion with the mounting bracket, so as to adjust the lower side of the snow shovel board 6 to abut against the ground; The pressure monitoring component 42 monitors the pressure at the mounting position of the connecting rod component 4. When the snow shovel 6 is blocked, the pressure on the connecting rod component 4 increases, and the second driving component 41 is controlled in cooperation with the control module 7 to drive the mounting bracket 3 to rotate upward. The pressure monitoring component 42 monitors the pressure of the mounting part of the connecting rod component 4. When the snow shovel 6 is suspended in the air, the pressure on the connecting rod component 4 is reduced, and the control module 7 cooperates with the second driving component 41 to drive the mounting bracket 3 to rotate downward to keep the snow shovel 6 in a ground-attached state. When the height of the accumulated snow in the snow shovel 6 reaches a preset height through the second visual monitoring component, the left / right direction without obstacles is determined through the first visual monitoring component 65, and the fourth driving component 61 is controlled in cooperation with the control module 7 to drive the snow shovel 6 to swing to the left / right side, pushing the accumulated snow to the left / right direction without obstacles; The first visual monitoring component 65 monitors obstacles, measures the width of the road surface required for snow shoveling, and cooperates with the control module 7 to control the fifth driving component 64 to drive the auxiliary snowboard 63 to unfold from both sides of the main snowboard 62 to the width of the road surface required for snow shoveling; If the width on one side is insufficient, the control module 7 controls the first driving assembly 21 to drive the connecting seat 2 to move left / right to adjust the length of one side of the snow shovel 6.

[0038] The chassis connection seat 2 of the existing snowplow has inconsistent heights from the ground, resulting in inadequate snow shoveling, especially when the ground is uneven. In order to solve this problem, the second drive component 41 drives the mounting bracket 3 to rotate up and down, and the pressure monitoring component 42 is combined to monitor the downward pressure of the snowplow 6, so that the contact state between the snowplow 6 and the ground can be accurately adjusted. When the snowplow 6 is blocked, the pressure increases, and the system automatically adjusts the mounting bracket 3 upward through the second drive component 41 to keep the snowplow 6 close to the ground; and when the snowplow 6 is suspended in the air, the pressure decreases, and the system automatically adjusts downward to ensure that the snowplow 6 can always be close to the ground for efficient snow shoveling.

[0039] Through the cooperation of the tripod 5 and the second driving assembly 41, the angle of the snowplow 6 can be adjusted according to the ground conditions to ensure that the snowplow 6 can maintain a good contact state under various complex terrains, thereby improving work efficiency and avoiding missing snow layers.

[0040] In order to adapt to different road widths, the auxiliary snowboard 63 and the main snowboard 62 are designed to expand / retract, and the auxiliary snowboard 63 is controlled by the fifth driving component 64 to expand and retract, so as to adapt to different road widths. In addition, the first driving component 21 drives the connecting seat 2 to move left / right, and the length of one side of the snow shovel board 6 can be flexibly adjusted to ensure that the snow shovel operation can be accurately covered under different road conditions.

[0041] The first visual monitoring component 65 and the second visual monitoring component 66 can monitor the snow height in the snow shovel 6 and the obstacles on both sides of the road in real time to ensure that the snow shovel operation can be carried out in an obstacle-free area. When the snow height reaches a preset value, the snow shovel 6 can automatically swing left / right to push the snow to the obstacle-free side, thereby improving work efficiency and coverage.

[0042] The snow shovel board 6 is provided with a plurality of movable wheels 8, which are rotatably mounted on both sides of the snow shovel board. When the ground is sloped or in other conditions, the movable wheels 8 can be adjusted to abut against the ground to assist in moving. A spring assembly 9 is fixedly mounted between the back of the snow shovel board 6 and the tripod 5 or the fourth drive assembly 61, which can reduce the shock of the snow shovel board 6.

[0043] Compared with the prior art, the height of the chassis connection seat 2 of the existing snowplow equipment from the ground is usually difficult to adapt to complex road conditions, and when the road surface is uneven, the snowplow 6 is prone to poor contact with the ground, resulting in poor snowplowing effect, or even the snowplow 6 tilting or unable to be effectively pushed forward.

[0044] The contact pressure between the snow shovel 6 and the ground is monitored in real time through the pressure monitoring component 42, and the upper and lower positions of the mounting bracket 3 are accurately adjusted using the second driving component 41. The height of the snow shovel 6 can be automatically adjusted according to the ground conditions to ensure that the snow shovel 6 is always in full contact with the ground, thereby avoiding poor operation due to inconsistent height from the ground.

[0045] Existing snowplows mostly realize the flipping of the snowplow plate 6 through a fixed tripod 5 and an articulated device, but the adaptability to complex road conditions and different terrains is limited, which easily causes difficulty in moving.

[0046] The tripod 5 and the second drive assembly 41 work together to adjust the angle of the snow shovel 6 to adapt to different road surfaces and obstacles. This adaptive function can effectively cope with different terrains, such as uneven roads, to ensure that the contact state of the snow shovel 6 is always optimal, thereby improving work efficiency.

[0047] Most snowplow equipment has poor adaptability to road width, and often requires repeated operations to completely clear the snow. In addition, the width of the snowplow plate 6 cannot be flexibly adjusted according to roads of different widths.

[0048] By driving the auxiliary snow plate 63 to be unfolded and retracted through the fifth driving component 64, the working width of the snowplow plate 6 can be automatically adjusted according to different road widths, thereby avoiding repeated operations, reducing workload, and being able to accurately cover roads of different widths.

[0049] In order to accurately control the left and right movement of the connecting seat 2, the first driving assembly 21 includes a group of first motors 211 fixedly mounted on the connecting seat 2, a gear 212 fixedly mounted on the output end of the first motor 211, and a sliding block 213 welded on the connecting seat 2 toward the gear 212, a groove 214 is provided on the sliding block 213, and the first motor 211 is electrically connected to the control module 7; The front fixing frame 1 is fixedly mounted with a guide rod 215 and a rack 216 arranged parallel to the guide rod 215; The gear 212 is meshed with the rack 216, and the sliding block 213 is slidably mounted on the guide rod 215 through the groove 214. The first motor 211 drives the gear 212 to rotate forward / reverse, and cooperates with the guide rod 215 and the sliding block 213 for guidance, and meshes with the rack 216 to drive the connecting seat 2 to move left / right. In this embodiment, a lateral compensation of ±30cm can be performed. By providing a combination of the first motor 211, the gear 212, the rack 216, the guide rod 215 and the sliding block 213, the connecting seat 2 can be accurately moved left and right in the lateral direction. This precise movement control is to flexibly adjust the working width or position of the snow shovel 6 according to the ground conditions, so as to ensure the efficiency and accuracy of the snow shovel operation. The snow shovel can be dynamically adjusted according to the different road widths, snow thicknesses and obstacles. For example, when facing a narrow road, the connecting seat 2 can move to one side to reduce the width of the snow shovel 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 more efficient operation coverage.

[0050] The combination of the guide rod 215 and the sliding block 213 can stabilize the sliding track of the snow shovel 6, ensuring that the left and right movement of the connecting seat 2 will not be affected by uneven pressure or external interference. The sliding block 213 slides in the groove 214 on the guide rod 215 to avoid uncontrolled deviation. The snow shovel 6 can be prevented from tilting or unbalanced due to uneven ground or uneven pressure, maintaining the stability and accuracy of the operation. In addition, the sliding of the sliding block 213 in the groove 214 can ensure that the snow shovel moves smoothly during the operation, reduce wear and tear, and extend the service life of the equipment.

[0051] In order to adapt to complex terrain and improve work efficiency, the meshing design of the gear 212 and the rack 216 is combined to make the transmission process more stable and the torque transmission efficiency high, and can adapt to complex terrain changes. This system not only ensures the stable operation of the snowplow on uneven roads, 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 snowplow plate 6 when facing different road conditions, and ensure the continuity and efficiency of the snowplow operation, especially in cities or more complex environments, which can significantly improve the coverage and accuracy of road clearing.

[0052] The guide between the sliding block 213 and the guide rod 215 is guided by the groove 214, which effectively reduces the relative friction between the components. At the same time, the meshing transmission mode of the gear 212 and the rack 216 is more stable, reducing excessive mechanical impact.

[0053] In order to achieve the up and down adjustment of the mounting bracket 3, the second driving assembly 41 includes a first hydraulic telescopic cylinder 411 fixedly installed in the middle part below the connecting seat 2. The output end of the first hydraulic telescopic cylinder 411 is rotatably installed in the middle part of the mounting bracket 3 through a pin shaft. The telescopic rod of the first hydraulic telescopic cylinder 411 is extended / retracted to push the mounting bracket 3 to rotate upward / downward around the mounting area of ​​the connecting seat 2.

[0054] By setting up a first hydraulic telescopic cylinder 411 and connecting its output end to the mounting bracket 3, the mounting bracket 3 can be adjusted up and down by the telescopic effect 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 shovel. The snow shovel is allowed to adjust the height of the snow shovel board 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 is thick, the mounting bracket 3 can be adjusted to a higher position to avoid the snow shovel board 6 from being stuck or damaged due to being too low; when the road surface is flat or the snow is thin, the height of the snow shovel board 6 can be lowered to improve the snow shoveling effect.

[0055] By adding the first hydraulic telescopic cylinder 411 to the second drive assembly 41, the mounting bracket 3 can be precisely adjusted up and down, which can improve the adaptability, stability and safety of the snow pusher under different ground conditions. This design not only enhances the flexibility and efficiency of the equipment, but also improves the operation accuracy, reduces manual intervention, and improves the degree of automation.

[0056] In order to achieve precise adjustment of the angle, the third driving assembly 51 includes a second motor 511 rotatably mounted on one side above the mounting bracket 3 via a pin shaft, an externally threaded rotating rod 512 inserted at the output end of the second motor 511, and an internally threaded tube 513 rotatably mounted on the tripod 5 via a pin shaft; The second motor 511 is electrically connected to the control module 7, and the control module 7 controls the second motor 511 to drive the external threaded rotating rod 512 to rotate forward / reverse. The angle between the tripod 5 and the mounting bracket 3 is adjusted by adjusting the length of the external threaded rotating rod 512 inserted in the internal threaded tube 513.

[0057] The external threaded rotating rod 512 is driven by the motor to rotate forward and reverse, and the relative movement between the external threaded rotating rod 512 and the internal threaded tube 513 can adjust the angle between the tripod 5 and the mounting bracket 3. The forward and reverse control of the motor provides a very precise adjustment capability. The angle adjustment can be precisely controlled according to actual needs, thereby optimizing the working angle and improving the working effect. For example, adjusting the angle helps to change the angle and working range of the snow shovel, so that it performs better in different working environments and improves the efficiency and accuracy of snow shoveling.

[0058] The second motor 511 is used to drive the external threaded rotating rod 512 to adjust the angle, rather than the traditional manual adjustment method. The motor is precisely controlled by the control module 7, which can make the adjustment process more stable and efficient.

[0059] In order to achieve lateral adjustment of the main snowboard 62 and the auxiliary snowboard 63, a group of guide grooves 621 are horizontally arranged on the side of the main snowboard 62 away from the tripod 5, and a guide bar 622 is arranged on the side of the auxiliary snowboard 63 facing the main snowboard 62 at a height corresponding to the guide groove 621, and the guide bar 622 is slidably inserted inside the guide groove 621.

[0060] The width of the open side of the guide groove 621 is smaller than the width of the closed bottom side thereof, and the guide bar 622 is adapted to the guide groove 621 .

[0061] In order to avoid the snowplow being overloaded due to excessive accumulation of snow on the snowplow board 6 during the movement of the snowplow, the traditional fixed snow throwing direction is prone to cause secondary accumulation.

[0062] The fourth driving assembly 61 includes a group of third hydraulic telescopic cylinders 611 rotatably mounted on both sides of the tripod 5, and the output ends of the third hydraulic telescopic cylinders 611 are fixedly mounted on the main snowboard 62. The control module 7 synchronously controls the extension of a telescopic rod in one of the third hydraulic telescopic cylinders 611 and the retraction of a telescopic rod in another of the third hydraulic telescopic cylinders 611, thereby pushing the main snowboard 62 to tilt 30-60° toward one side.

[0063] By cooperating with the first visual monitoring component 65 and the second visual monitoring component 66, under certain conditions, such as when the snow accumulation in the snow shovel 6 exceeds 80% or there are unavoidable obstacles, the telescopic rod in one of the third hydraulic telescopic cylinders 611 is controlled to extend, and the telescopic rod in the other third hydraulic telescopic cylinder 611 is retracted, pushing the main snow board 62 to tilt 30-60° to one side.

[0064] The fifth driving 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, and the control module 7 controls the extension / retraction of the telescopic rod in the second hydraulic telescopic cylinder 641 to push the auxiliary snowboard 63 to be laterally deployed / retracted. In this embodiment, the electric telescopic adjustment within the range of 0.5-3.2 meters can be performed.

[0065] Through the design of the guide groove 621 and the guide bar 622, the auxiliary snowboard 63 can be adjusted to slide sideways on the main snowboard 62. The guide groove 621 is provided with openings of different widths to ensure that the guide bar 622 can slide stably therein, so as to adjust the position of the auxiliary snowboard 63 when necessary. The auxiliary snowboard 63 can be flexibly adjusted to adapt to different snow conditions and operation requirements. For example, on a wider snow trail, 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, thereby improving the flexibility and efficiency of snow shoveling operations.

[0066] By designing the width of the open side of the guide groove 621 to be smaller than the width of the bottom closed side, the design of the guide bar 622 and the guide groove 621 makes the movement of the auxiliary snowboard 63 smoother and limited by the structure of the guide groove 621. The structural design of the guide groove 621 can effectively control the movement range of the auxiliary snowboard 63, avoiding excessive or unstable lateral movement of the auxiliary snowboard 63. The stability of the auxiliary snowboard 63 during movement is ensured, and accidents or improper operation caused by the auxiliary snowboard 63 sliding too fast or too slow are avoided, thereby improving the accuracy and safety of the operation. In addition, it is ensured that the retraction and deployment of the auxiliary snowboard 63 can be carried out within the predetermined range, avoiding damage to the equipment or affecting the operation effect.

[0067] Among them, the lateral deployment and retraction of the auxiliary snow board 63 are controlled by the second hydraulic telescopic cylinder 641, and the hydraulic telescopic cylinder can adjust the deployment angle or retraction state of the auxiliary snow board 63 according to the instructions of the control module 7. This cylinder system can provide a wide range of force and precise control. It can respond flexibly according to different snow layer conditions and working environments. For example, when encountering heavier snow or a wide working area, the auxiliary snow board 63 can be deployed to increase the snow pushing area and improve the working efficiency; in places where the space is narrow or the snow layer is thin, the auxiliary snow board 63 can be retracted to reduce the occupation of the working area and ensure the maneuverability of the equipment.

[0068] 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 auxiliary snowboard 63 can be flexibly deployed and retracted. Not only does it improve the adaptability and efficiency of the equipment, but it also improves the stability and safety of the operation through automation and precise control. The flexible adjustment function of the auxiliary snowboard 63 enables the equipment to quickly respond to changes in different operating environments, greatly improving work efficiency and operation quality.

[0069] As a further improvement, the first visual monitoring component 65 is installed at the outer edge position above the auxiliary snowboard 63, and the first visual monitoring component 65 includes a biological monitoring sensor and a non-biological monitoring sensor, and the biological monitoring sensor and the non-biological monitoring sensor are electrically connected to the control module 7; The biological monitoring sensor detects pedestrians and animals, and the non-biological monitoring sensor monitors obstacles. The second visual monitoring component 66 is vertically installed on the outer side above the main snowboard 62, and determines the snow height by monitoring the remaining visible area of ​​the main snowboard 62.

[0070] Among them, biological monitoring sensors are mainly used to identify the presence of organisms, usually including thermal imaging sensors, infrared sensors, ultrasonic sensors, etc. They can detect human body temperature, animal movement or sound, and are mainly used to monitor pedestrians and animals.

[0071] For example, a thermal imaging sensor can detect organisms with a temperature different from the environment. If there is a pedestrian on the left, the sensor will sense the pedestrian's heat and determine its position and movement.

[0072] As for non-biological monitoring sensors, this type 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.

[0073] For example, lidar can build a three-dimensional map of surrounding obstacles by emitting laser beams and receiving their reflected signals, determine whether there are obstacles, and measure the distance.

[0074] The monitoring logic and application scenario are set. When there is someone on the left side, when the biological monitoring sensor (such as an infrared sensor) on the left side detects the heat change of a biological body, the control module 7 will recognize that there is a pedestrian or animal on the left side.

[0075] According to the preset safety logic, the control module 7 can trigger an alarm or automatically slow down, adjust the working range of the left auxiliary snowboard 63, and avoid collision with pedestrians or animals.

[0076] When there is a person on the right side, when the biological monitoring sensor (such as an infrared sensor) on the right side detects the heat change of a biological body, the control module 7 will recognize that there is a pedestrian or animal on the left side.

[0077] According to the preset safety logic, the control module 7 can trigger an alarm or automatically slow down, adjust the working range of the right auxiliary snowboard 63, and avoid collision with pedestrians or animals.

[0078] 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 a laser radar or an ultrasonic sensor) will detect the presence of an obstacle in front or on the left. When the obstacle enters the detection range, the sensor will measure the distance and shape of the object. The control module 7 will determine the type and distance of the obstacle, and then the control module 7 will cooperate with the fifth drive component 64 to retract the auxiliary snowboard 63. When the obstacle is unavoidable, the snow shovel board 6 will be controlled to tilt toward the side without the obstacle by cooperating with the fourth drive component 61 to avoid the obstacle.

[0079] When the sensors simultaneously detect a pedestrian on the left and an obstacle on the right, the biological monitoring sensor and the non-biological monitoring sensor provide information simultaneously.

[0080] Depending on the design priorities, human safety is prioritized. For example, assuming that a pedestrian on the left side has a higher priority, the system may immediately take action (such as slowing down or adjusting the auxiliary ski 63) to avoid the pedestrian.

[0081] If the obstacle on the right cannot be avoided (such as a large rock), the system can avoid the threat to pedestrians by slowing down, stopping or adjusting the operating trajectory, while also avoiding collision with the obstacle.

[0082] The second visual monitoring component 66 (such as a laser radar or a visual sensor) is installed above the main snowboard 62 to vertically monitor the height of the snow in front of the main snowboard 62. The sensor determines the thickness of the snow by scanning the ground. The control module 7 automatically adjusts the deployment angle or retraction state of the auxiliary snowboard 63 by analyzing the height of the snow. 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 work force.

[0083] In order to improve the structural stability and strength, the connecting rod assembly 4 includes a group of support rods 43 and a support rod 44 connecting two of the support rods 43. Through holes 45 are provided at both ends of the support rods 43. The two ends of the support rods 43 are respectively inserted into the through holes 45 through pins and rotatably mounted on the connecting seat 2 and the mounting support. The pressure monitoring assembly 42 includes a pressure sensor 46 , and the pressure sensor 46 is embedded and installed above the interior of the through hole 45 .

[0084] Through holes 45 are provided at both ends of the support rod 43, and the support rod 43 is rotatably connected to the connection seat 2 and the mounting support through a pin shaft to form a solid structure. The rotation connection method of the pin shaft can ensure that the support rod 43 is not easy to fall off or loosen during movement, and can provide sufficient supporting force to ensure the overall stability of the device.

[0085] This setting can effectively disperse loads and stresses, especially when the equipment is subjected to large external forces or vibrations, which can reduce the risk of damage and improve the durability and reliability of the system.

[0086] The two ends of the support rod 43 are respectively mounted on the connecting seat 2 and the mounting support by means of a pin shaft, which not only has a simple structure, but also facilitates later installation and removal. The user can easily install or remove the support rod 43, and no complicated tools or large-scale disassembly are required during maintenance.

[0087] In addition, the rotational connections in this solution are all connected by pins.

[0088] The pressure sensor 46 is embedded and installed above the inside of the through hole 45, and can accurately monitor the pressure changes in the through hole 45. Since the position of the sensor is close to the force point, the pressure on the connecting component can be reflected in real time, thereby ensuring effective monitoring of the equipment pressure.

[0089] The load changes of the connecting rod assembly 4 are monitored in real time through the pressure sensor 46: when the pressure value exceeds the safety threshold (suspended state), the second drive 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), the reverse drive is used to restore the snow shovel 6 to the ground, forming a closed-loop control circuit.

[0090] When the snow shovel 6 is blocked, the protrusion of the mounting bracket inserted in the through hole 45 applies force to the side opposite to the through hole 45 where the pressure sensor 46 is mounted, so that the pressure on the pressure sensor 46 is reduced; When the snow shovel 6 is suspended in the air, the protrusion of the mounting bracket inserted in the through hole 45 applies force to the side of the through hole 45 where the pressure sensor 46 is mounted, so that the pressure on the pressure sensor 46 increases.
