Description

Technical Field

[0001] The invention belongs to the technical field of engineering vehicles, and in particular relates to a snowplow and an engineering vehicle. Background Art

[0002] Snow accumulation on roads and sites has long been the culprit causing losses to human production activities and posing threats to personal safety. A snowplow is an effective snow removal tool that can be installed on loaders, trucks, pickups, forklifts and other engineering vehicles for road snow removal operations.

[0003] Regardless of the type of vehicle it is installed on, since the snowplow cannot adjust its height and angle according to the road conditions, there is a risk of excessive contact with the ground, causing damage to the snowplow or the road surface, especially for uneven roads and roads with large slope angles, where the snowplow will be damaged by the instantaneous impact of the road surface. At present, there is almost no anti-contact solution for domestic snowplows, which cannot effectively alleviate the problem of high impact force when the snowplow contacts the ground. The impact force when the snowplow touches the bottom is strong, which is easy to cause damage to the shovel blade and the ground. Summary of the invention

[0004] The main purpose of the present invention is to provide a snowplow and an engineering vehicle, aiming to solve the technical problem in the prior art that the snowplow easily causes damage to the shovel blade and the ground.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a snow pusher, which includes: a snow pusher body, including a main shovel and a blade hinged to the lower end of the main shovel; a shock-absorbing mechanism, including a protective pad and a shock-absorbing assembly, the protective pad is installed on the blade through the shock-absorbing assembly, the shock-absorbing assembly is used to absorb kinetic energy through its own deformation, and the bottom surface of the protective pad is lower than the bottom surface of the blade.

[0006] In an embodiment of the present invention, the shock-absorbing assembly includes: a telescopic adjustment member installed on the blade; a shock-absorbing member, the telescopic adjustment member is connected to the protective pad through the shock-absorbing member, the telescopic adjustment member can be telescoped in the up and down directions, and adjust the height of the protective pad from the ground.

[0007] In an embodiment of the present invention, the telescopic adjustment member is a hydraulic cylinder; and / or the shock absorbing member is a gas spring.

[0008] In an embodiment of the present invention, the main shovel and the shovel blade are hinged via a flip shaft, and the snow pusher further comprises a return torsion spring sleeved outside the flip shaft, and the return torsion spring and the flip shaft are coaxially arranged.

[0009] In the embodiment of the present invention, a connecting frame is provided at a position of the blade close to the main shovel, the shock absorbing assembly is installed on the connecting frame, and the connecting frame is hinged to the main shovel via a flip shaft.

[0010] In an embodiment of the present invention, the snow pusher further comprises a corner observation mast fixed on the top of the main shovel.

[0011] In the embodiment of the present invention, corner observation masts are provided at the top corners of the main shovel.

[0012] In an embodiment of the present invention, the snow pusher further comprises: a quick-change interface for quick connection to an engineering vehicle; and a swing cylinder, wherein the quick-change interface is connected to the main shovel via the swing cylinder.

[0013] In the embodiment of the present invention, a reinforced connection component is further connected between the quick-change interface and the main shovel.

[0014] The present invention also provides an engineering vehicle, which includes the snowplow as described above.

[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The snow pusher according to the present invention will be described below with reference to the accompanying drawings.

[0038] like Figures 1 to 3 As shown, in an embodiment of the present invention, a snow shovel 100 includes a snow shovel body 1 and a shock-absorbing mechanism. The snow shovel body 1 includes a main shovel 11 and a blade 12 hinged to the lower end of the main shovel 11; the shock-absorbing mechanism includes a protective pad 2 and a shock-absorbing assembly 3. The protective pad 2 is installed on the blade 12 through the shock-absorbing assembly 3. The shock-absorbing assembly 3 is used to absorb kinetic energy through its own deformation, and the lowest point of the protective pad 2 is lower than the lowest point of the blade 12. Specifically, the bottom surface of the protective pad 2 is lower than the bottom surface of the blade 12. The shock-absorbing mechanism is arranged near the lower end of the snow shovel body 1, and the shock-absorbing assembly 3 is located at the connection between the main shovel 11 and the blade 12.

[0039] It can be understood that the snow pusher 100 in this embodiment is mainly used in engineering vehicles, the blade 12 can be flipped and installed at the lower end of the main shovel 11, the pad 2 can be made of wear-resistant material, and the shock absorbing mechanism has elasticity. The width direction of the snow pusher 100 is the left-right direction, the height direction of the snow pusher 100 is the up-down direction, and the thickness direction of the snow pusher 100 is the front-back direction.

[0040] The cushioning assembly 3 in this embodiment is connected to the pad 2 at the bottom, and connected to the blade 12 at the top. When in use, the lower surface height of the pad 2 is adjusted to be slightly lower than the blade 12. When touching the ground, the pad 2 first contacts the ground. The contraction of the cushioning assembly 3 absorbs kinetic energy, which can alleviate the rigid impact of the blade 12 when touching the ground, avoid damage to the blade 12, the main shovel 11 or the ground, and protect the snow shovel 100 and the road surface. Under normal circumstances, it does not affect the advancement of the main shovel 11 and the blade 12, nor does it affect the flipping of the blade 12 when passing through obstacles. In this embodiment, by connecting the cushion 2 with the cushioning assembly 3 to the blade 12, and making the bottom surface of the cushion 2 lower than the bottom surface of the blade 12, the height of the cushion 2 and the ground is small, which can ensure that the cushioning assembly 3 contacts the ground first, and the contraction of the cushioning assembly 3 absorbs kinetic energy, alleviates the rigid impact of the snow shovel 100 and the ground, and avoids damage to the snow shovel 100 and the ground.

[0041] like Figure 3 As shown, the shock absorbing assembly 3 includes a telescopic adjusting member 31 and a shock absorbing member 32. The telescopic adjusting member 31 is installed on the blade 12. The telescopic adjusting member 31 is connected to the protective pad 2 through the shock absorbing member 32. The telescopic adjusting member 31 can be telescoped in the up and down directions and adjust the height of the protective pad 2 from the ground.

[0042] The telescopic adjustment member 31 in this embodiment can be telescopically extended and retracted in the up and down directions, and drive the shock-absorbing member 32 to rise and fall in the up and down directions, thereby adjusting the height of the protective pad 2 connected to the lower end of the shock-absorbing member 32 from the ground, ensuring that the bottom surface of the protective pad 2 is lower than the bottom surface of the shovel blade 12, and the up and down position adjustment of the protective pad 2 is achieved by adjusting the telescopic stroke of the telescopic adjustment member 31. The telescopic adjustment member 31 can be positioned to any position within the stroke range of the telescopic adjustment member 31 without the need for manual operation by the operator, and the adjustment range is large and the operation is convenient.

[0043] In one embodiment, the telescopic adjustment member 31 may be a hydraulic cylinder, and the shock absorbing member 32 may be a gas spring.

The shock-absorbing member 32 includes a spring rod 322 and a spring sleeve 321 sleeved outside the spring rod 322. The lower end of the spring rod 322 can be connected to the protective pad 2 by a hinged bolt. The spring rod 322 may include a thin rod and a thick rod connected to the lower end of the thin rod. The upper end of the thin rod is inserted into the spring sleeve 321, and the thick rod is connected to the protective pad 2. The cross-sectional size of the thick rod is larger than the cross-sectional size of the thin rod, which can ensure the connection strength between the spring rod 322 and the protective pad 2; the telescopic adjustment member 31 includes a piston rod 312 and a cylinder 311 sleeved outside the piston rod 312. The cylinder 311 is connected to the main shovel 11. The piston rod 312 and the spring sleeve 321 can be connected by a hinged bolt. The piston rod 312 may include a small head and a large head connected to the lower end of the small head. The cross-sectional size of the large head is larger than the cross-sectional size of the small head. The top of the small head is inserted into the cylinder 311, and the large head is sleeved outside the spring sleeve 321 and connected to the spring sleeve 321. The protective pad 2 may include a connecting platform and a protective platform disposed at the bottom of the connecting platform. The cross-sectional dimensions of the protective platform are larger than the cross-sectional dimensions of the connecting platform. The connecting platform is sleeved outside the thick rod and connected to the thick rod by hinged bolts. The cylinder 311 may be fixed to the blade 12. The upper and lower positions of the protective pad 2 may be adjusted by adjusting the stroke of the piston rod 312 to obtain the required positioning height of the protective pad 2. The adjustable range is large, and the operator does not need to manually adjust the protective pad 2. The structure is simple. In another embodiment, the shock absorbing member 32 may be an ordinary spring.

[0044] It should be noted that the main shovel 11 and the shovel blade 12 are hinged via a flip shaft, and the snow pusher 100 further includes a reset torsion spring 13 sleeved outside the flip shaft, and the reset torsion spring 13 and the flip shaft are coaxially arranged. The reset torsion spring 13 in this embodiment is axially coincident with the flip shaft, and can smoothly complete the flipping and resetting of the shovel blade 12 when passing an obstacle. Under the premise of also being able to complete the flipping and resetting of the shovel blade 12, compared with the commonly used tension spring in the prior art, the structure is simple, the space occupied is small, and the assembly is convenient, which reduces the manufacturing and assembly difficulties.

[0045] like Figure 1As shown, the blade 12 is provided with a connecting frame 121 near the main shovel 11, the damping assembly 3 is installed on the connecting frame 121, and the connecting frame 121 is hinged to the main shovel 11 through a flip shaft. The connecting frame 121 in this embodiment can be a rectangular tube extending in the left and right direction, the width of the rectangular tube is consistent with the width of the blade 12, the connecting frame 121 is fixed to the blade 12, and can be welded to the back of the blade 12, the main shovel 11 can be provided with a first ear plate, and the connecting frame 121 can be provided with a second ear plate, the number of the first ear plate and the second ear plate can be multiple, the number is consistent and one-to-one corresponding, the first ear plate and the second ear plate can be hinged through the flip shaft, the two ends of the rectangular tube can be vertically connected to the telescopic adjustment member 31 through the upper and lower surface openings, and the damping mechanism can be fixed, and the outer cover of the flip shaft is provided with a reset torsion spring 13. In this embodiment, the damping and reset obstacle avoidance functions can be integrated through the connecting frame 121, and the integrity is strong, and it is ensured that the pad 2 and the blade 12 are flipped together when passing an obstacle, and the obstacle avoidance function of the snow pusher 100 is not affected.

[0046] Specifically, the snow shovel 100 also includes a corner observation mast 111 fixed on the top of the main shovel 11. A corner observation mast 111 is arranged above the main shovel 11, and the corner observation mast 111 extends in the up-down direction and is in the shape of a thin rod. When the snow shovel 100 is loaded on an engineering vehicle with poor vision, the driver can observe and adjust the left and right turning angles of the snow shovel 100 through the corner observation mast 111, which enhances the applicability of the snow shovel 100, improves the driver's vision, and facilitates observation of the working turning angle of the snow shovel.

[0047] In one embodiment, a corner observation mast 111 is provided at the top corner of the main shovel 11. The corner observation mast 111 is provided at the left and right corners above the main shovel 11, which can prevent the snow shovel 100 from being unable to be observed when the snow shovel is in a low position during operation and is installed in an engineering vehicle with a high cab. The corner observation mast 111 can facilitate the driver to observe the left and right corners of the snow shovel 100 when the driver cannot see or cannot see the snow shovel 100 clearly, thereby improving the driver's field of vision.

The swing cylinder 5 in this embodiment can adopt a steering hydraulic cylinder, and the output end of the steering hydraulic cylinder is connected to the main shovel 11 and is used to drive the main shovel 11 to steer. The quick-change interface 4 in this embodiment may include a quick-connect seat 41 and a quick-connect shaft 42. The quick-connect seat 41 may be a triangular seat, which can be detachably connected through the quick-connect shaft 42 and the quick-connect seat 41, so that the snow shovel 100 and the engineering vehicle can be disassembled. The structure is simple and easy to assemble. The number of swing cylinders 5 can be set according to actual usage requirements, such as Figure 1As shown, the two swing cylinders 5 are arranged at intervals along the width direction of the main shovel 11, and the quick-connect shaft 42 is consistent with the width direction of the main shovel 11. In order to ensure the structural strength of the main shovel 11, the back of the main shovel 11 can be provided with reinforcing ribs extending in the up-down direction, and a plurality of arc-shaped reinforcing ribs are arranged at intervals along the width direction of the main shovel 11, and the length of the reinforcing ribs in the up-down direction is consistent with the length of the main shovel 11 in the up-down direction.

[0049] In one embodiment, a reinforced connection assembly 6 is further connected between the quick-change interface 4 and the main shovel 11. The reinforced connection assembly 6 in this embodiment may include a reinforced seat 61 disposed on the back of the main shovel 11, a triangular plate 62 mounted on the reinforced seat 61, and an articulated seat 63 mounted on the quick-change interface 4.
