Abstract
Description
Technical Field
[0001] This utility model discloses a free-floating snowplow and snow removal vehicle, belonging to the field of snow removal machinery manufacturing technology. Background Technology
[0002] In winter snow removal operations, snowplows, as a very common snow removal tool, play an indispensable role in ensuring smooth roads due to their high snow removal efficiency, strong environmental adaptability, and low failure rate. Traditional snowplows rely primarily on a linkage connected to the vehicle to swing up and down for vertical floating; while horizontal floating relies on the coordinated operation of the linkage, the central pin of the snowplow, and left and right pressure springs. The pin is responsible for horizontal swinging, and the pressure springs are responsible for automatic reset.
[0003] However, this free-floating mechanism has a significant inherent constraint, resulting in excessively strong reset force. In actual snow removal operations, considering the typically higher elevation in the middle of the road, this forced reset characteristic easily leads to greater wear on the left side of the snowplow compared to the right. After several snow removal operations, the blade will become uneven, with one side higher than the other. This not only necessitates premature replacement of the left blade while the right blade remains tilted, significantly increasing operating costs, but also results in a high equipment failure rate and severe blade waste, seriously impacting the economy and efficiency of snow removal operations.

Detailed Implementation
[0025] The following is based on the appendix Figure 1-9 Further explanation of this utility model:
[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] like Figure 1As shown, the first embodiment of this utility model provides a free-floating snowplow based on the prior art, including: a floating mechanism 100, one end of which is connected to one side of a snowplow frame assembly 200, and a plurality of snowplow shovel assemblies 300 arranged sequentially on the side of the snowplow frame assembly 200 away from the floating mechanism 100; wherein, the floating mechanism 100 is used to drive the snowplow frame assembly 200 and the plurality of snowplow shovel assemblies 300 to move horizontally or vertically.
[0030] The floating mechanism 100 can drive the snowplow frame assembly 200 and the snowplow assembly 300 to move horizontally, thereby changing the traditional forced reset method relying on pins and compression springs and avoiding uneven wear of the blades caused by forced reset. The vertical movement function can further optimize the up-and-down floating mechanism of the snowplow. Compared with the traditional method that only relies on linkage swing, it may make the snowplow more flexible in adapting to road undulations, reduce additional wear on the blades caused by uneven road surfaces, thereby reducing operating costs and equipment failure rate, and improving the economy and efficiency of snow removal operations.
[0031] like Figure 2-4 As shown, the floating mechanism 100 includes: a hanger assembly 101 and a first V-shaped connecting rod 102. The first end and the second segment of the first V-shaped connecting rod 102 are respectively hinged to the first end of the hanger assembly 101. The first end and the second segment of the second V-shaped connecting rod 107 are respectively hinged to the second end of the hanger assembly 101. The third end of the first V-shaped connecting rod 102 and the third end of the second V-shaped connecting rod 107 are respectively hinged to both ends of one side of the swing frame assembly 104. The other side of the swing frame assembly 104 is hinged to one side of the connector 105. The two ends of the swing frame assembly 104 are respectively hinged to the base ends of two drive cylinders 106. The two ends of the connector 105 are respectively hinged to the execution ends of two drive cylinders 106. The middle part of the second end of the hanger assembly 101 is hinged to the base end of the adjusting cylinder 103. The execution end of the adjusting cylinder 103 is hinged to the third end of the first V-shaped connecting rod 102.
[0032] The first V-shaped connecting rod 102 and the second V-shaped connecting rod 107 are hinged to both ends of the hanger assembly 101, and their third ends are hinged to the swing frame assembly 104. This multi-set hinge structure allows the floating mechanism to rotate flexibly in both horizontal and vertical directions. When encountering complex road conditions, the snowplow assembly can precisely adjust its angle and position by utilizing the movement of these hinge points to better conform to the road surface and ensure effective snow removal. For example, when navigating a curve, the snowplow can make minor horizontal adjustments based on the road curvature using the hinge structure, ensuring that the blade always removes snow along the tangent of the curve, preventing snow accumulation.
[0033] Two drive cylinders 106 are hinged at one end to both sides of the swing frame assembly 104 and at the other end to the connecting piece 105. Simultaneously, one end of the adjusting cylinder 103 is hinged to the hanging assembly 101 and at the other end to the third end of the first V-shaped connecting rod 102. The drive cylinders and adjusting cylinders work together to precisely control the movement of the floating mechanism. For example, when facing undulating road surfaces, the drive cylinder 106 can precisely control the swing amplitude of the swing frame assembly 104 according to the vertical drop of the road surface, driving the snowplow assembly to move vertically; the adjusting cylinder 103 can fine-tune the angle of the first V-shaped connecting rod 102, assisting the snowplow in better adapting to road surface changes in the horizontal direction, thereby improving snow removal efficiency.
[0034] The floating mechanism features a compact and rational layout of its components, achieving multiple functions within a limited space. The components, such as the hanger assembly 101, the V-shaped connecting rod, and the swing frame assembly, work together seamlessly without excessive redundancy. This ensures the mechanism's stability and strength without occupying too much installation space. Consequently, installing the floating mechanism on a snowplow does not significantly impact the vehicle's original spatial layout, facilitating its adaptation and installation on different types of snowplows.
[0035] Furthermore, such as Figures 5-9 As shown, the snowplow frame assembly 200 includes a sliding device that slides vertically with the frame assembly 202, and multiple snowplow assemblies 300 are disposed on the side of the frame assembly 202 away from the sliding device. The sliding device includes a connecting plate 203, one side of which is connected to the side of the connector 105 away from the swing frame assembly 104, and two first limiting plates 206 are symmetrically arranged on the other side of the connecting plate 203. At least two sleeves 205 are symmetrically arranged on the first limiting plates 206. Two second limiting plates 201 are respectively arranged at the upper and lower ends of the side of the frame assembly 202 away from the snowplow assemblies 300. At least two optical axes 207 are respectively arranged on the two second limiting plates 201, and at least two sleeves 205 are respectively sleeved on the at least two optical axes 207. The sliding device also includes: a plurality of first shock-absorbing rubber blocks 204, which are respectively disposed on the outside of the two first limiting plates 206, and the plurality of first shock-absorbing rubber blocks 204 are used to cooperate with the inside of the two second limiting plates 201.
[0036] The sliding device, through the cooperation of the sleeve 205 and the optical axis 207, achieves vertical sliding with the frame assembly 202. This design allows the snowplow assembly 300 to adjust its height in real time according to the vertical undulations of the road surface. When encountering potholes, the snowplow can slide down along the optical axis 207 with the frame assembly 202, keeping the blade in contact with the ground to ensure that the snow is completely removed; while at road bumps, it can automatically slide upwards, avoiding excessive wear of the blade and equipment damage, greatly improving the adaptability of snow removal operations to different road conditions.
[0037] Multiple first and second shock-absorbing rubber blocks 204 are respectively installed on the inner and outer sides of the limiting plate 206, cooperating with the inner side of the limiting plate 201. These shock-absorbing rubber blocks play an important role in snow removal operations. When the snowplow encounters obstacles or uneven road surfaces and vibrates, the shock-absorbing rubber blocks can effectively absorb and buffer the vibration energy. On the one hand, this reduces the impact of vibration on equipment components, extending the service life of the equipment; on the other hand, it improves the stability during operation, making the driver's operation smoother and improving the quality and efficiency of snow removal operations.
[0038] Furthermore, the snowplow assembly 300 includes: a front shovel assembly 303, which is disposed on the side of the frame assembly 202 away from the sliding device; one end of the inner side of the front shovel assembly 303 is hinged to one end of two welded hinge rods 302, and the other ends of the two welded hinge rods 302 are hinged to the lower end of the frame assembly 202; the middle part of the inner side of the front shovel assembly 303 is hinged to one end of two front connecting rods 304, and the other ends of the two front connecting rods 304 are hinged to one end of two V-shaped rear upper connecting rods 306. Then, the other ends of the two V-shaped upper rear connecting rods 306 are respectively hinged to the upper end of the frame assembly 202. The inner middle part of the front shovel assembly 303 is respectively connected to one end of at least two springs 305. The other ends of the two springs 305 are respectively hinged to the lower middle part of the frame assembly 202. A third limiting plate 307 is provided in the inner middle part of the front shovel assembly 303. A second shock-absorbing rubber block 308 that cooperates with the third limiting plate 307 is provided on the side of the frame assembly 202 away from the sliding device. One end of the outer side of the front shovel assembly 303 is connected to the blade 301.
[0039] The front shovel assembly 303 is hinged to the lower end of the frame assembly 202 via a welded hinge rod 302, and simultaneously hinged to the upper end of the frame assembly 202 via a front connecting rod 304 and a V-shaped rear upper connecting rod 306. This multi-link hinge structure gives the front shovel assembly 303 great flexibility. During snow removal, when encountering local obstacles or special terrain on the road surface, the front shovel assembly 303 can swing around the hinge point. For example, when passing through areas with irregular stones on the roadside, the front shovel can flexibly avoid the stones and continue to efficiently remove snow without being damaged by colliding with obstacles, significantly improving the snowplow's ability to cope with complex road conditions.
[0040] At least two springs 305 are connected at one end to the inner middle of the front shovel assembly 303 and at the other end to the lower middle of the frame assembly 202. Simultaneously, a limiting plate 307 at the inner middle of the front shovel assembly 303 engages with a second shock-absorbing rubber block 308 on the frame assembly 202. During snowplow operation, the springs absorb most of the impact force caused by uneven road surfaces, providing initial cushioning. When the impact force is large, the limiting plate 307 and the second shock-absorbing rubber block 308 interact to further buffer the remaining impact energy. This not only reduces vibration damage to the front shovel assembly 303 and the entire equipment but also ensures that the blade 301 maintains good contact with the ground, improving snow removal efficiency and extending the equipment's service life.
[0041] One end of the front shovel assembly 303 is directly connected to the blade 301. This simple and direct connection makes it extremely convenient to replace the blade 301 when it wears out. Maintenance personnel can quickly replace the blade by simply removing the corresponding connecting parts, without having to disassemble the entire snowplow assembly. This greatly shortens maintenance time, reduces maintenance costs, and improves equipment availability.
[0042] The second embodiment of this utility model provides a snow removal vehicle based on the first embodiment, including a vehicle body and a free-floating snowplow as described in the first embodiment.
[0043] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
