Description

Technical Field

[0001] This utility model discloses a floating snowplow device, belonging to the technical field of snow removal equipment. Background Technology

[0002] In snow removal operations, roller brushes are the most commonly used snow removal machinery, especially when used in conjunction with de-icing agents, which has a good snow removal effect. However, they also have the fatal drawback of causing the death of garden plants and trees.

[0003] During operation, snow removal rollers need to be angled to the vehicle to push the snow towards one side of the angle. Snow treated with de-icing agents contains a large amount of sodium chloride. While the snow on the road is being swept away, the high speed and angle of the rollers also instantly throw salt snow into the green belts. In cities with heavy snowfall in winter, especially when de-icing agents are used for snow removal, the green belts in the middle of the road and the green belts on both sides of the road die every spring due to the falling salt snow. This causes losses to the landscaping departments. Removing the dead plants and replanting the same varieties results in a huge waste of manpower and financial resources, and increases the government's financial expenditure. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing snow removal rollers throw salt and snow into the green belt during snow removal due to high rotation speed and tilt angle. The invention proposes a method that addresses this issue by using high rotation speed and tilt angle.

[0005] The problem to be solved by this utility model is achieved by the following technical solution:

[0006] A floating snowplow device includes a device connecting frame connected to the front end of a snowplow vehicle. The device connecting frame has a roller brush bracket and auxiliary moving wheels respectively provided at its front end and on both sides. A roller brush assembly is rotatably mounted at the front end of the roller brush bracket. The roller brush assembly is driven by a motor provided on one side of the roller brush bracket. A roller brush cover is fixed on the roller brush bracket and placed on the top of the roller brush assembly. The two ends of the front side of the roller brush bracket are connected to the floating obstacle-crossing shovel assembly through a spring linkage structure. The height of the shovel end of the floating obstacle-crossing shovel assembly is smaller than the radius of the roller brush assembly.

[0007] Preferably, the spring linkage structure includes a first tension spring mounting plate disposed at both ends of the roller brush bracket, the first tension spring mounting plate being connected to one end of two tension springs respectively, and the other end of the two tension springs being connected to a second tension spring mounting plate disposed on the floating obstacle-crossing shovel assembly.

[0008] Preferably, the spring linkage structure further includes two spring limiting plates fixed to both ends of the roller brush bracket, the two spring limiting plates being respectively disposed on both sides of the first tension spring mounting plate and the second tension spring mounting plate, and the two spring limiting plates being connected together by a connecting column.

[0009] Preferably, the floating obstacle-crossing shovel assembly includes a floating support frame. The front end of the floating support frame is hinged to the protrusions of multiple arc-shaped shovel plates. The front bottom ends of the multiple arc-shaped shovel plates are respectively connected to shovel blades. The rear top ends of the multiple arc-shaped shovel plates are symmetrically connected to one end of two shovel plate springs. The other ends of the two shovel plate springs are connected to a connecting plate on the floating support frame. A support column is provided on one side of the floating support frame of the connecting plate. A lifting rod is inserted into the support column. The ends of the two lifting rods are connected together by a lifting connecting rod. The lifting connecting rod is fitted with multiple flap sleeves. The multiple flap sleeves are connected by flaps. The ends of the flaps are connected by an adjustable pull line. The side of the lifting rod is provided with a lifting rod positioning hole. The support column is limited to the lifting rod by cooperating with the lifting rod positioning hole through a positioning pin. One end of the positioning pin is connected to one end of a limit line. When the lifting rod is engaged with the support column, the other end of the limit line is provided with a pull ring sleeve, and the other end of the pull ring sleeve is fitted onto the other end of the positioning pin.

[0010] Preferably, each of the multiple flip plates has a rubber plate at its front end.

[0011] Preferably, multiple rubber strips are provided on the outer ends of the multiple flaps near both ends of the floating support frame.

[0012] The advantages of this invention compared to existing technologies are as follows:

[0013] This utility model discloses a floating snowplow device. A floating obstacle-crossing shovel assembly is installed at both ends of the front side of the roller brush bracket via a spring linkage structure. The spring linkage structure has a vertical floating function and can generate vertical and horizontal obstacle avoidance when impacted. The top of the shovel blade in the floating obstacle-crossing shovel assembly is equipped with a vertical height adjustment flap. The flap can be adjusted for the front and rear tilt angle via an adjustable pull cable. The height of the segmented combined shovel blade is less than the radius of the roller brush.

[0014] Therefore, when the roller brush assembly performs the sweeping operation, the blade first pushes the snow on the road surface in the same direction as the roller brush assembly sweeping, thus reducing the power of the roller brush sweeping operation. The roller brush assembly only sweeps the snow remaining after the snowplow operation. At the same time, when the roller brush assembly sweeps, it also throws the salt and snow towards the front of the snowplow through the tangential principle. Meanwhile, because the flap acts as a blocking device, the salt and snow can only splash to the front of the snowplow and cannot splash higher or farther.

[0015] This invention has a simple structure, which reduces the power required by the snow sweeping brush during snow removal operations and lowers the rotation speed. It also solves the problem of salt and snow splashing into the green belt during snow sweeping operations, making snow removal faster, saving fuel and not damaging the plants in the green belt.

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.

[0027] 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.

[0028] like Figure 1 As shown, the first embodiment of this utility model provides a floating snowplow device based on the prior art. It includes a device connecting frame 100 connected to the front end of a snowplow vehicle. A roller brush bracket 300 and auxiliary moving wheels 200 are respectively installed on the front end and both sides of the device connecting frame 100. A roller brush assembly 500 is rotatably mounted on the front end of the roller brush bracket 300. The roller brush assembly 500 is driven by a motor 400 installed on one side of the roller brush bracket 300. A roller brush cover 600 is fixed on the roller brush bracket 300, covering the top of the roller brush assembly 500. The two front ends of the roller brush bracket 300 are connected to a floating obstacle-crossing shovel assembly 800 via a spring-link structure 900. The height of the shovel end of the floating obstacle-crossing shovel assembly 800 is less than the radius of the roller brush assembly 500. In this embodiment, the structures of the device connecting frame 100, auxiliary moving wheels 200, roller brush bracket 300, motor 400, and roller brush assembly 500 are common knowledge to those skilled in the art, and are sufficient to achieve the corresponding functions; therefore, they will not be described in detail further. The following will detail the specific structure of the spring linkage structure 900 and the floating obstacle-crossing shovel assembly 800 and their interconnections.

[0029] like Figure 2 and 3As shown, the spring linkage structure 900 includes a first tension spring mounting plate 902 installed at both ends of the roller brush bracket 300. The first tension spring mounting plate 902 is connected to one end of two tension springs 903, and the other end of the two tension springs 903 is connected to a second tension spring mounting plate 905 installed on the floating obstacle-crossing shovel assembly 800. The spring linkage structure 900 also includes two spring limiting plates 901 fixed at both ends of the roller brush bracket 300. The two spring limiting plates 901 are respectively installed on both sides of the first tension spring mounting plate 902 and the second tension spring mounting plate 905, and the two spring limiting plates 901 are connected together by a connecting post 904. This enables the roller brush bracket to float up and down, and when impacted, it can avoid obstacles in all directions. The two spring limiting plates 901 prevent the two tension springs 903 from moving left and right.

[0030] like Figure 3-7 As shown, the floating obstacle-crossing shovel assembly 800 includes a floating support frame 801. The front end of the floating support frame 801 is hinged to the protrusions of a plurality of arc-shaped shovel plates 812. The front bottom ends of the plurality of arc-shaped shovel plates 812 are respectively connected to shovel blades 813. The rear top ends of the plurality of arc-shaped shovel plates 812 are respectively symmetrically connected to one end of two shovel plate springs 811. The other ends of the two shovel plate springs 811 are connected to a connecting plate 802 on the floating support frame 801. A support column 809 is installed on the floating support frame 801 on one side of the connecting plate 802. A lifting rod 805 is inserted into the support column 809. The ends of the two lifting rods 805 are connected together by a lifting connecting rod 806. A plurality of flap sleeves are fitted on the lifting connecting rod 806. The tube 807 and multiple flap sleeves 807 are connected by flaps 815. The ends of the flaps 815 are connected by adjustable pull lines 700. The flaps can be adjusted for front and rear tilt angles via the adjustable pull lines. The height of the segmented combined shovel blade is less than the radius of the roller brush. The side of the lifting rod 805 is provided with a lifting rod positioning hole 814. The support column 809 is positioned with the lifting rod 805 by a positioning pin 810 cooperating with the positioning hole 814. One end of the positioning pin 810 is connected to one end of the limiting line 804. When the lifting rod 805 and the support column 809 are in the limiting engagement, the other end of the limiting line 804 is provided with a pull ring sleeve, the other end of which is sleeved on the other end of the positioning pin 810, thereby realizing the adjustment of the vertical height and front and rear tilt angle of the flaps 815. Rubber plates 808 are installed at the front ends of the multiple flaps 815 respectively. Multiple rubber strips 803 are installed at the outer ends of the flaps 815 near the two ends of the floating support frame 801 respectively.

[0031] Therefore, when the roller brush assembly 300 performs its sweeping operation, the blades first push the snow on the road surface in the same direction as the roller brush assembly 300's sweeping. This reduces the power required for the roller brush sweeping operation. The roller brush assembly 300 also removes residual snow after the snowplowing operation. Simultaneously, the roller brush assembly 300, through its sweeping action, throws the salt and snow towards the front of the snowplow using a tangential principle. Furthermore, the flap acts as a barrier, preventing the salt and snow from splashing higher or farther. This embodiment has a simple structure, reduces the power required by the snow-sweeping roller brush during snow removal operations, lowers the rotation speed, and solves the problem of salt and snow splashing into the green belt during roller brush sweeping operations. This results in faster snow removal, fuel savings, and no damage to the vegetation in the green belt.

[0032] 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.
