Description

Technical Field

[0001] The invention discloses a free-floating snowplow and a snow-removing vehicle, belonging to the technical field of snow-removing machinery manufacturing. Background Art

[0002] In winter snow removal operations, snowplows are a very common snow removal tool. With its high snow removal efficiency, strong environmental adaptability and low failure rate, they play an indispensable and key role in ensuring smooth roads. The traditional snowplows mainly rely on the up and down swing of the connecting rod connected to the vehicle to achieve the up and down floating function; while the left and right floating function is achieved by the coordinated operation of the connecting rod, the pin in the center of the snowplow and the left and right compression springs. The pin is responsible for the left and right swing, and the compression spring is responsible for the automatic reset task.

[0003] However, this left-right free floating mechanism is obviously mandatory, and the reset force is too strong. In actual snow removal operations, considering the terrain characteristics of the middle of the road, which is usually higher, the forced reset characteristics can easily cause the left side of the snowplow to suffer greater wear and tear, and the wear rate is faster than the right side. After several snow removal operations, the shovel blade will appear to be higher on one side and lower on the other. This situation not only requires the left shovel blade to be replaced in advance, but the right shovel blade is still in a skewed state, which greatly increases the operating cost, but also leads to a high equipment failure rate and extremely serious waste of shovel blades, which seriously affects the economy and efficiency of snow removal operations. Summary of the invention

DETAILED DESCRIPTION

[0025] The following is based on the attached Figure 1-9 The present invention is further described:

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1As shown, the first embodiment of the present invention provides a free-floating snowplow based on the prior art, including: a floating mechanism 100, one end of the floating mechanism 100 is connected to one side of a snow removal frame assembly 200, and a plurality of snowplow assemblies 300 are arranged in sequence on the side of the snow removal frame assembly 200 away from the floating mechanism 100; wherein the floating mechanism 100 is used to drive the snow removal frame assembly 200 and the plurality of snowplow assemblies 300 to move horizontally or vertically.

[0030] The floating mechanism 100 can drive the snow removal frame assembly 200 and the snow pusher assembly 300 to move horizontally, thereby changing the traditional forced reset method relying on the pin and the compression spring, and avoiding uneven wear of the shovel blade due to forced reset. The function of moving in the vertical direction can further optimize the up and down floating mechanism of the snow removal shovel. Compared with the traditional method of relying only on the swing of the connecting rod, the snow removal shovel may adapt to the ups and downs of the road more flexibly, reduce the additional wear of the shovel blade caused by the uneven road surface, and thus reduce the operating cost and equipment failure rate, and improve the economy and efficiency of snow removal operations.

[0031] like Figure 2-4 As shown, the floating mechanism 100 includes: a hanging assembly 101 and a first V-shaped connecting rod 102, wherein the first end and the second section of the first V-shaped connecting rod 102 are respectively hinged to the first end of the hanging assembly 101, and the first V-shaped connecting rod 102. The first end and the second section of the second V-shaped connecting rod 107 are respectively hinged to the second end of the hanging 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 the two ends of one side of the swing frame assembly 104, and the other side of the swing frame assembly 104 is hinged to one side of the connecting member 105, and the two side ends of the swing frame assembly 104 are respectively hinged to the base ends of the two driving cylinders 106, and the two ends of the connecting member 105 are respectively hinged to the execution ends of the two driving cylinders 106, and the middle part of the second end of the hanging assembly 101 is hinged to the base end of the adjusting cylinder 103, and 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 respectively hinged to the two ends of the hanging assembly 101, and their third ends are hinged to the swing frame assembly 104. This multi-group hinge structure enables the floating mechanism to rotate flexibly in both horizontal and vertical directions. When encountering complex road conditions, the snowplow assembly can use the activities of these hinge points to accurately adjust the angle and position to better fit the road surface and ensure the snow removal effect. For example, when passing through a curve, the snowplow can use the hinge structure to achieve horizontal fine-tuning according to the curvature of the road surface to ensure that the shovel blade always removes snow along the tangent direction of the curve to avoid residual snow.

[0033] One end of the two driving cylinders 106 is hinged to the two side ends of the swing frame assembly 104, and the other end is hinged to the connecting piece 105. At the same time, one end of the adjusting cylinder 103 is hinged to the hanging assembly 101, and the other end is hinged to the third end of the first V-shaped connecting rod 102. The driving cylinder and the adjusting cylinder work together to accurately control the movement of the floating mechanism. For example, when facing an undulating road surface, the driving cylinder 106 can accurately control the swing amplitude of the swing frame assembly 104 according to the vertical drop of the road surface, and drive the snow pusher assembly to move in the vertical direction; the adjusting cylinder 103 can fine-tune the angle of the first V-shaped connecting rod 102, and assist the snow pusher to better adapt to the changes in the road surface in the horizontal direction, thereby improving the snow removal efficiency.

[0034] The components of the floating mechanism are compactly and reasonably arranged, and multiple functions are realized in a limited space. The components such as the hanging assembly 101, the V-shaped connecting rod and the swing frame assembly cooperate with each other without excessive redundant structures, which not only ensures the stability and strength of the mechanism, but also does not occupy too much installation space. This ensures that after the floating mechanism is installed, the snow pusher will not have a significant impact on the original space layout of the vehicle, and is convenient for adaptation and installation on different types of snow removal vehicles.

[0035] Furthermore, if Figure 5-Figure 9 As shown, the snow removal frame assembly 200 includes: a sliding device, which is vertically slidably matched with the frame assembly 202, and a plurality of snow pusher assemblies 300 are arranged on the side of the frame assembly 202 away from the sliding device. The sliding device includes: a connecting plate 203, one side of the connecting plate 203 is connected to the side of the connecting member 105 away from the swing frame assembly 104, and the other side of the connecting plate 203 is symmetrically provided with two limit plates 206, and at least two sleeves 205 are symmetrically arranged on the limit plates 206, and the upper and lower ends of the side of the frame assembly 202 away from the snow pusher assembly 300 are respectively two limit plates 201, and the two limit plates 201 are respectively provided with at least two optical axes 207, 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 piers 204, a plurality of second shock-absorbing rubber piers are respectively arranged on the outside of the two limit plates 206, and a plurality of second shock-absorbing rubber piers of the connecting member are used to cooperate with the inner sides of the two limit plates 201.

[0036] The sliding device realizes vertical sliding with the frame assembly 202 through the cooperation of the sleeve 205 and the optical axis 207. This design enables the snow pusher assembly 300 to adjust its height in real time according to the vertical ups and downs of the road surface. When encountering potholes on the road surface, the snow pusher can slide down along the optical axis 207 with the frame assembly 202, keeping the shovel blade in contact with the ground to ensure that the snow can be completely cleared; and on the convex part of the road surface, it can automatically slide up to avoid excessive wear of the shovel blade and damage to the equipment, greatly improving the adaptability of snow removal operations to different road conditions.

[0037] A plurality of first shock-absorbing rubber piers 204 and second shock-absorbing rubber piers are respectively arranged on the inner and outer sides of the limit plate 206, and cooperate with the inner side of the limit plate 201. These shock-absorbing rubber piers play an important role in the snow removal operation. When the snowplow encounters obstacles or uneven roads and generates vibrations, the shock-absorbing rubber piers can effectively absorb and buffer the vibration energy. On the one hand, the impact of vibration on equipment parts is reduced, and the service life of the equipment is extended; on the other hand, the stability during the operation is improved, making the driver's operation more stable, and improving the quality and efficiency of snow removal operations.

[0038] Furthermore, the snow pusher assembly 300 includes: a front shovel assembly 303, which is arranged 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 respectively hinged to one end of two welded hinge rods 302, the other ends of the two welded hinge rods 302 are respectively hinged to the lower end of the frame assembly 202, the middle part of the inner side of the front shovel assembly 303 is respectively hinged to one end of two front connecting rods 304, the other ends of the two front connecting rods 304 are respectively hinged to one end of two V-shaped rear upper connecting rods 306. The front shovel assembly 303 is hinged at the inner middle part, the other ends of the two V-shaped rear upper 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 middle and lower parts of the frame assembly 202, a limiting plate 307 is provided in the inner middle part of the front shovel assembly 303, and a second shock-absorbing rubber pier 308 cooperating with the limiting plate 307 is provided on the side of the frame assembly 202 away from the sliding device, and one end of the outer side of the front shovel assembly 303 is connected to the shovel blade 301.

[0039] The front shovel assembly 303 is hinged to the lower end of the frame assembly 202 by welding the hinge rod 302, and is hinged to the upper end of the frame assembly 202 by means of the front connecting rod 304 and the V-shaped rear upper connecting rod 306. This multi-link hinge structure gives the front shovel assembly 303 great flexibility. During the snow removal process, when encountering local obstacles or special terrain on the road, the front shovel assembly 303 can swing around the hinge point. For example, when passing through an area with irregular stones on the roadside, the front shovel can flexibly avoid the stones and continue to maintain efficient snow removal without causing damage to the equipment due to collision with obstacles, which significantly improves the snowplow's ability to cope with complex road conditions.

[0040] At least two springs 305 are connected to the middle part of the inner side of the front shovel assembly 303 at one end, and are hinged to the middle and lower part of the frame assembly 202 at the other end. At the same time, the limit plate 307 at the middle part of the inner side of the front shovel assembly 303 cooperates with the second shock-absorbing rubber pier 308 on the frame assembly 202. When the snow shovel is in operation, the spring can absorb most of the impact force caused by the uneven road surface and play a primary buffering role. When the impact force is large, the limit plate 307 interacts with the second shock-absorbing rubber pier 308 to further buffer the remaining impact energy. This not only reduces the damage caused by vibration to the front shovel assembly 303 and the entire equipment, but also ensures that the shovel blade 301 always maintains good contact with the ground, improving the snow removal effect while extending the service life of the equipment.

[0041] One end of the outer side of the front shovel assembly 303 is directly connected to the shovel blade 301. This simple and direct connection method makes it extremely convenient to operate when the shovel blade 301 is worn and needs to be replaced. The maintenance personnel only need to remove the corresponding connection parts to quickly replace the shovel blade without large-scale disassembly of the entire snow pusher assembly, which greatly shortens the maintenance time, reduces maintenance costs, and improves the availability of the equipment.

[0042] A second embodiment of the present invention provides a snow removal vehicle based on the first embodiment, including a vehicle body and a free-floating snowplow according to the first embodiment.

[0043] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
