Description

Technical Field

[0001] This invention belongs to the field of snow plow technology, specifically relating to a mechanism for realizing multi-angle movement of the snow plow in a snow groomer. Background Technology

[0002] Snow groomers are core specialized equipment for the construction, daily maintenance, and leveling of ski slopes in ski resorts. The snowplow, as the core working component of the snow groomer that directly performs the leveling work, directly determines the quality and efficiency of the leveling operation through its motion adjustment capabilities and terrain adaptability. In actual ski slope leveling operations, the terrain is limited by the natural conditions of the ski resort, making it impossible to achieve a completely flat surface. Furthermore, different operating scenarios require different adjustments to the snowplow's working posture. Therefore, the snowplow mechanism needs to have multi-degree-of-freedom adjustment capabilities. It must be able to lift, turn, swing, and perform combined movements of the snowplow to adapt to the posture adjustment needs of different operating scenarios. Simultaneously, the snowplow needs to be able to adaptively float within a certain range according to changes in terrain, ensuring a stable fit between the snowplow's working surface and the snow surface, avoiding problems such as uneven leveling, missed areas, and excessive undulations in the working surface.

[0003] Currently, the snowplow movement adjustment mechanism of existing snow groomers is in use as follows: 1. Most snowplow motion mechanisms can only achieve single or two degrees of freedom motion adjustment, and cannot simultaneously accommodate the full compound motion adjustment of snowplow lifting, turning angle, and swing angle. They have poor operational flexibility and are difficult to adapt to the full-scene smoothing operation requirements of complex terrain snow tracks. When facing snow tracks with curves, slope changes, and terrain undulations, frequent machine stops and adjustments are required, resulting in low operational efficiency. Second, the existing snowplow mechanism has insufficient terrain-adaptive floating capability. Most of them adopt a rigid connection structure and can only make passive position adjustments by driving the hydraulic cylinder. They cannot achieve adaptive floating of the snowplow according to the real-time undulation of the snow track. When there are bumps or depressions in the terrain, the fit between the snowplow and the snow surface decreases significantly, which directly leads to poor uniformity of the snow track and cannot meet the operation requirements of high-standard snow tracks. Third, some snowplow mechanisms with floating functions have unreasonable layout of shock-absorbing floating components, resulting in poor buffering and shock absorption. During operation, the rigid impact load from the terrain is directly transmitted to the hinge joint between the snow groomer and the mechanism, which can easily cause fatigue damage to the hinge shaft and load-bearing structure, significantly reducing the service life of the mechanism. At the same time, the lack of a stable and reliable limiting structure makes it impossible to accurately control the floating stroke, which can easily lead to overload failure of elastic components and impact damage to the mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanism for realizing multi-angle movement of the snowplow in a snow groomer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanism for realizing multi-angle movement of the snowplow in a snow groomer, comprising a main unit connecting frame, a swing arm support assembly, a main load-bearing crossbeam, and a snowplow mounting connection frame. The rear end of the main unit connecting frame is connected to the front end of the main load-bearing crossbeam via a hinge structure. Swing arm support assemblies are symmetrically and fixedly connected to the left and right sides of the main load-bearing crossbeam. An elastic shock-absorbing floating assembly for realizing adaptive floating of the snowplow is provided between the main load-bearing crossbeam and the swing arm support assembly. A motion cavity for mounting the snowplow mounting connection frame is provided between the two swing arm support assemblies. The lower end of the swing arm support assembly is hinged to the lower part of the snowplow mounting connection frame via a lower swing arm hinge pin. The main unit connecting frame is provided with multiple sets of pins for connecting the drive cylinder.

[0006] In a preferred embodiment, the top of the main unit connecting frame is provided with a main unit connecting plate shaft, the middle of the main unit connecting frame is provided with a middle connecting plate shaft, the lower part of the main unit connecting frame is provided with a main unit frame lower hinge seat, and both sides of the bottom of the main unit connecting frame are provided with corner cylinder hinge seats. Both corner cylinder hinge seats are hinged to the snowmobile chassis through corner cylinders.

[0007] In a preferred embodiment, limit connecting seats are fixedly provided on both the left and right sides of the main load-bearing crossbeam. The elastic damping floating component is installed above the limit connecting seats. The lower end of the elastic damping floating component is fixedly connected to the limit connecting seats, and its upper end is limitedly engaged with the floating mechanism support seat.

[0008] In a preferred embodiment, a swing cylinder support is fixedly installed on the upper part of the main load-bearing crossbeam, and a rear lifting cylinder support is installed at the center of the lower rear end of the main load-bearing crossbeam. A lifting cylinder is hinged to the bottom of the rear lifting cylinder support, and the other end of the lifting cylinder is hinged to the lower hinge seat of the main frame.

[0009] In a preferred embodiment, the floating mechanism support is located at the upper end of the elastic shock-absorbing floating assembly, and a gap is provided between the lower end of the floating mechanism support and the limiting connection seat to allow the elastic shock-absorbing floating assembly to float. The side of the floating mechanism support is welded to the outer wall of the swing arm support assembly.

[0010] In a preferred embodiment, the upper part of the floating mechanism support is integrally formed with a protective cover reinforcing limiting block. The lower end face of the protective cover reinforcing limiting block abuts against the upper end face of the elastic shock-absorbing floating component, and the protective cover reinforcing limiting block is used to limit the vertical floating stroke of the elastic shock-absorbing floating component.

[0011] In a preferred embodiment, the upper part of the snowplow mounting frame is symmetrically fixed with a swing angle hinge seat, and one side of the swing angle hinge seat is provided with a snowplow support groove.

[0012] In a preferred embodiment, a snowplow floating rotation shaft is provided between the main load-bearing crossbeam and the swing arm support assembly.

[0013] In a preferred embodiment, the main connecting plate shaft is used to connect the main frame of the snowmobile. The middle connecting plate shaft is hinged to one end of the main load-bearing crossbeam. An angle cylinder is hinged inside the angle cylinder support on the crossbeam, and the other end of the angle cylinder is hinged to the angle hinge seat.

[0014] In a preferred embodiment, both ends of the lower swing arm hinge pin and the snowplow tray are provided with anti-detachment limiting components. One end of the snowplow body is embedded inside the snowplow tray, and both sides of the snowplow body are hinged to the outside of the lower swing arm hinge pin.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The mechanism that enables the snowplow of the snow groomer to move at multiple angles is designed with a main frame with multiple sets of hinged plate shafts, a main load-bearing crossbeam, a snowplow floating rotation shaft, and a matching hinge point layout. It can simultaneously accommodate the snowplow's lifting, turning, swinging, and combined motion adjustments, adapting to the posture adjustment needs of different snow track operation scenarios and effectively improving the flexibility and efficiency of snow track leveling operations.

[0016] The mechanism that enables the snow plow of the snow groomer to move at multiple angles uses an elastic shock-absorbing floating component set between the main load-bearing crossbeam and the swing arm support assembly, in conjunction with a limiting structure, to allow the snow plow to adaptively float within a set range according to changes in the terrain of the snow track. This ensures stable contact between the snow plow and the snow surface during operation, while also buffering the rigid impact caused by terrain undulations and preventing the working load from being directly transmitted to the snow groomer main unit and the mechanism hinge.

[0017] The mechanism that enables the snowplow of the snow groomer to move at multiple angles is improved by symmetrically arranged swing arm support components, integrated main load-bearing beam structure and optimized hinge design. This improves the overall torsional stiffness and heavy load-bearing capacity of the mechanism, avoids mechanism interference during multi-degree-of-freedom compound movements, reduces wear of hinge components and risk of structural fatigue damage, extends the service life of the mechanism and ensures the operational stability during operation.

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1 - Figure 6This invention provides a mechanism for realizing multi-angle movement of the snowplow in a snow groomer, including a main frame connecting frame 1, a swing arm support assembly 2, a main load-bearing crossbeam 3, and a snowplow mounting connection frame 6. The rear end of the main frame connecting frame 1 is connected to the front end of the main load-bearing crossbeam 3 via a hinge structure. The swing arm support assemblies 2 are symmetrically fixedly connected to the left and right sides of the main load-bearing crossbeam 3. An elastic shock-absorbing floating assembly 4 for realizing adaptive floating of the snowplow is provided between the main load-bearing crossbeam 3 and the swing arm support assembly 2. A motion cavity 201 for mounting the snowplow mounting connection frame 6 is provided between the two swing arm support assemblies 2. The lower end of the swing arm support assembly 2 is hinged to the lower part of the snowplow mounting connection frame 6 via a lower swing arm hinge pin 5. The main frame connecting frame 1 is provided with multiple sets of pins for connecting the drive cylinder. The top of the main frame connecting frame 1 is provided with a main frame connecting plate shaft 102, the middle part of the main frame connecting frame 1 is provided with a middle connecting plate shaft 103, and the lower part of the main frame connecting frame 1 is provided with a main frame lower hinge seat 101. Both sides of the bottom of the machine connecting frame 1 are provided with corner cylinder hinge seats 104. Both corner cylinder hinge seats 104 are hinged to the snowmobile chassis through corner cylinders 10. Limiting connecting seats 303 are fixedly provided on both the left and right sides of the main load-bearing crossbeam 3. Elastic shock-absorbing floating components 4 are installed above the limiting connecting seats 303. The lower end of the elastic shock-absorbing floating components 4 is fixedly connected to the limiting connecting seats 303, and its upper end is limitedly matched with the floating mechanism support seat 7. The upper part of the main load-bearing crossbeam 3 is fixed. A swing cylinder support 301 is fixedly provided on the crossbeam. A rear lifting cylinder support 302 is provided at the center of the lower rear end of the main load-bearing crossbeam 3. A lifting cylinder 9 is hinged to the bottom of the rear lifting cylinder support 302. The other end of the lifting cylinder 9 is hinged to the lower hinge seat 101 of the main frame. A floating mechanism support 7 is provided at the upper end of the elastic shock-absorbing floating component 4. A gap is provided between the lower end of the floating mechanism support 7 and the limiting connection seat 303 to allow the elastic shock-absorbing floating component 4 to float.

[0023] Before operation, the main unit connecting frame 1 is fixedly connected to the snow groomer frame via the top main unit connecting plate shaft 102 to form the mounting base of the entire mechanism. The rear end of the main unit connecting frame 1 is hinged to the front end of the main load-bearing crossbeam 3 via the middle connecting plate shaft 103, providing the main load-bearing crossbeam 3 with pitch and swing freedom relative to the main unit. The swing arm support components 2 are symmetrically distributed on the left and right sides of the main load-bearing crossbeam 3. The components enclose each other to form a motion cavity 201 that accommodates the snow plow mounting connecting frame 6, providing a non-interference activity space for the multi-degree-of-freedom movement of the snow plow. The lower end of the swing arm support component 2 is hinged to the lower part of the snow plow mounting connecting frame 6 via the lower swing arm hinge pin 5, forming the lower support rotation point of the snow plow. One end of the snow plow body is embedded in the snow plow tray 602, and the two sides are hinged to the outside of the lower swing arm hinge pin 5. The working load is transmitted to the main unit connecting frame 1 in sequence through the snow plow body, snow plow mounting connecting frame 6, swing arm support component 2, and main load-bearing crossbeam 3.

[0024] When the snowplow is lifting, the lifting cylinder 9 extends and retracts. One end rotates around the lower hinge seat 101 of the main frame, while the other end drives the main load-bearing crossbeam 3 to swing around the central connecting plate shaft 103. This, in turn, drives the snowplow mounting frame 6 and the snowplow body to complete the overall lifting and lowering through the swing arm support assembly 2. When the snowplow is turning, the corner cylinders 10 on the two corner cylinder hinge seats 104 extend and retract in coordination, pushing the main frame 1 to rotate horizontally around the main frame connecting plate shaft 102. This drives the entire mechanism to complete the left and right corner adjustment synchronously with the snowplow. The corner cylinder hinge seat 104 also acts as a hard limit, precisely limiting the maximum corner stroke of the snowplow.

[0025] Please see Figure 1 - Figure 6 The upper part of the floating mechanism support 7 is integrally formed with a protective cover and a reinforcing limiting block 701. The lower end face of the protective cover and the reinforcing limiting block 701 abuts against the upper end face of the elastic shock-absorbing floating component 4. The protective cover and the reinforcing limiting block 701 is used to limit the vertical floating stroke of the elastic shock-absorbing floating component 4. The upper part of the snowplow mounting bracket 6 is symmetrically fixed with a swing angle hinge seat 601. The rear side of the swing angle hinge seat 601 is provided with a snowplow groove 602. A snowplow is provided between the main load-bearing crossbeam 3 and the swing arm support component 2. The floating rotating shaft 8 and the main connecting plate shaft 102 are used to connect the snowmobile frame. The middle connecting plate shaft 103 is hinged to one end of the main load-bearing crossbeam 3. The swing cylinder 11 is hinged inside the swing cylinder support 301 on the crossbeam. The other end of the swing cylinder 11 is hinged to the swing hinge seat 601. The lower swing arm hinge pin 5 and both ends of the snowplow tray 602 are provided with anti-detachment limiting parts. One end of the snowplow body is embedded in the snowplow tray 602, and the two sides of the snowplow body are hinged to the outside of the lower swing arm hinge pin 5. When the snowplow is tilting, the tilting cylinder 11 extends and retracts. One end of the cylinder rotates around the tilting cylinder support 301 on the crossbeam, while the other end drives the snowplow mounting frame 6 to move through the tilting hinge seat 601. The snowplow mounting frame 6 uses the lower swing arm hinge pin 5 as the rotation axis, which drives the snowplow body to adjust the working tilt angle, so as to realize the snowplow snow removal and snow track leveling operation. The extension and retraction of the tilting cylinder 11 determines the tilting angle of the snowplow, which can be flexibly adjusted according to the snow track thickness and operation requirements.

[0026] When the snow track has undulations, the reaction force of the snow surface is transmitted through the snowplow body to the snowplow mounting bracket 6, and then through the swing arm support assembly 2 to the elastic shock-absorbing floating assembly 4. The elastic shock-absorbing floating assembly 4 is installed above the limiting connecting seat 303. The upper end of the elastic shock-absorbing floating assembly 4 abuts against the protective cover reinforced limiting block 701. By setting the limiting gap and its own elastic deformation, it absorbs the impact load brought by the terrain undulations, and drives the swing arm support assembly 2 and the snowplow to make vertical adaptive floating. The side of the floating mechanism support seat 7 is welded and fixed to the swing arm support assembly 2. A floating gap is reserved between its lower end and the limiting connecting seat 303 to ensure the smooth floating of the elastic shock-absorbing floating assembly 4. The protective cover reinforced limiting block 701 forms a hard limit when the elastic assembly is compressed to the limit, limiting its maximum floating stroke.

[0027] The snowplow floating rotation shaft 8 on the main load-bearing crossbeam 3 is the central rotating shaft for snowplow floating, providing stable rotational support during the snowplow's adaptive floating process. Anti-detachment limiting components are installed at both ends of the lower swing arm hinge pin 5 and the snowplow tray 602 to limit the axial movement of the pin and prevent the pin from coming out of the hinge hole under operational vibration and impact. All hinged parts adopt a rotating connection method with pin engagement to ensure the smooth movement of each component.

[0028] The working principle and usage process of this invention are as follows: Before operation, the main unit connecting frame 1 is fixedly connected to the snowmobile frame via the top main unit connecting plate shaft 102. One end of the snowplow body is embedded in the snowplow tray 602 of the snowplow mounting connecting frame 6, and both sides are hinged to the outside of the lower swing arm hinge pin 5. During operation, the lifting cylinder 9 extends and retracts, with one end rotating around the lower hinge seat 101 of the main unit frame, and the other end driving the main bearing beam 3 to pitch and swing around the middle connecting plate shaft 103. The snowplow is lifted and lowered as a whole through the swing arm support assembly 2 and the snowplow mounting connecting frame 6. The corner cylinders 10 on the two side corner cylinder hinge seats 104 extend and retract in coordination, pushing the main unit connecting frame 1 to rotate horizontally around the main unit connecting plate shaft 102, thereby driving the snowplow. After completing the left and right angle adjustment, the swing cylinder 11 extends and retracts. One end rotates around the swing cylinder support 301 on the crossbeam, and the other end drives the snowplow mounting frame 6 through the swing hinge seat 601. The lower swing arm hinge pin 5 is used as the rotation point to drive the snowplow to make pitching and swinging motion, adjusting the snowplow's working tilt angle. When the snow track has undulations, the snow surface reaction force is transmitted through the snowplow, snowplow mounting frame 6, and swing arm support assembly 2 to the elastic shock-absorbing floating assembly 4 above the limit connection seat 303. Through elastic deformation, the snowplow is driven to float vertically adaptively within the stroke limited by the protective cover reinforcement limit stop 701. Throughout the entire process, the anti-detachment limiters at both ends of the lower swing arm hinge pin 5 and the snowplow tray 602 prevent the pin from axially moving out.
