Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically to a swirling cover shell anti-splash structure and a snowplow. Background Technology

[0002] Snowplows, as efficient snow removal equipment, are widely used in municipal roads, parks, residential areas, and other places. The snowplow's agitator system is one of its core working components. Its main function is to collect and break up the snow on the ground, and then throw the snow from the snow outlet to a designated location through snow-throwing blades.

[0003] However, the existing snowplow swivel cover has obvious defects in actual use: because the swivel blades and snow throwing blades generate strong centrifugal force when they rotate at high speed, and the rotation axis of the swivel blades is perpendicular to the rotation axis of the snow throwing blades in space, the snow is prone to fly out disorderly under the action of the swivel blades and snow throwing blades. That is, the snow shoveled by the swivel blades will be carried by the snow throwing blades and fly out from the top of the swivel cover and the gap on the side near the snow outlet.

[0004] This snow splashing phenomenon not only prevents large amounts of snow from being properly collected and dispersed, significantly reducing snow removal efficiency, but also affects already cleared areas. Furthermore, it poses a safety hazard: splashed snow particles may strike pedestrians. Therefore, there is an urgent need for a snow-splashing swirl shell structure that can effectively block snow splashing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a swirling cover shell anti-splash structure and a snow sweeper, so as to solve or at least alleviate one or more of the above-mentioned technical problems or other problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a splash-proof structure for a swirling cover shell, comprising a cover body, including an arc-shaped shell and a cylindrical body disposed on the arc-shaped shell. The two sides of the arc-shaped shell along its length are respectively referred to as the first side and the second side. The arc-shaped shell has a connection port with a circular inner wall. The cylindrical body communicates with the connection port. The cylindrical body is provided with a snow outlet, which is located on the rear side of the arc-shaped shell and close to the first side. A first stop is disposed on the inner wall of the connection port near the first side. The first stop is spatially perpendicular to the axis of the cylindrical body, and the top of the first stop is close to the lowest point of the snow outlet.

[0007] Preferably, the first stop has an outer arc surface, the center of which coincides with the center of the connection port, and the outer arc surface is attached to the inner wall of the connection port.

[0008] Preferably, the first stop has an inner arc surface, the center of which coincides with the center of the connection port.

[0009] Preferably, the ratio of the width of the first stop to the radius of the connection port is in the range of 0.1 to 0.16.

[0010] Preferably, it further includes a second stop, which is disposed on the inner wall of the arc-shaped housing and close to the first side. The second stop extends along the length direction of the arc-shaped housing, and the bottom end of the second stop is raised towards the front side of the arc-shaped housing. The height of the second stop is higher than the height of the center of the connection port.

[0011] Preferably, the height of the second stop is lower than the height of the highest point of the connection port.

[0012] Preferably, the second stop is located above the first stop.

[0013] Preferably, the top of the second stop is provided with a mounting block, which is disposed on the inner wall of the arc-shaped housing.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a snowplow with a swirling shell anti-splash structure. By adding a first stop block inside the connection port, the position and layout of the first stop block can specifically intercept snow shoveled by the snow-throwing blades, as well as some snow that attempts to splash out of the connection port due to centrifugal force, so that it can be smoothly thrown to the snow outlet. This optimizes the movement trajectory of snow in the cylinder, reduces the possibility of snow splashing from the top and the first side, reduces the impact on pedestrians and cleared areas, solves the defect of snow splashing easily when existing snowplows are working, and effectively improves the working efficiency, cleanliness and safety of the snowplow.

[0032] like Figure 1-5 As shown, in one embodiment of this utility model, a splash-proof structure for a swirling cover shell is provided, including a shell body and a first baffle 30. The shell body 10 includes an arc-shaped shell 11 and a cylindrical body 12 fixedly installed on the arc-shaped shell 11. The left and right sides of the arc-shaped shell 11 along its length are respectively referred to as the first side 13 and the second side 14. The arc-shaped shell 11 has a connection port 15 with a circular inner wall. The cylindrical body 12 communicates with the connection port 15 to form a channel for snow to enter the cylindrical body 12 from the arc-shaped shell 11. The cylindrical body 12 is provided with a snow outlet 16, which is located on the rear side of the arc-shaped shell 11 ("rear side" refers to the side of the arc-shaped shell 11 away from its arc-shaped opening) and close to the first side 13.

[0033] The snow-throwing blade 20 is rotatably mounted inside the cylinder 12, with its rotation axis coinciding with the axis of the cylinder 12. Three snow-throwing blades 21 are evenly distributed on the snow-throwing blade 20. Each snow-throwing blade 21 has a recessed groove 22 on its surface. The groove 22 can "catch" the snow entering the cylinder 12 when the snow-throwing blade 21 rotates, and throw the snow along the tangent of the groove 22 towards the snow outlet 16 through centrifugal force.

[0034] The first baffle 30 is the core component to prevent snow from splashing. The first baffle 30 is fixedly installed on the inner wall of the connection port 15 near the first side 13. The first baffle 30 is perpendicular to the axis of the cylinder 12 in space. The top of the first baffle 30 is close to the lowest point of the snow outlet 16.

[0035] As the snow-throwing blades 21 rotate at high speed toward the snow outlet 16, they carry away the snow shoveled by the stirring blades 40 toward the connection port 15, causing some snow to splash upwards toward the connection port 15 and onto the first side 13. This embodiment discloses a stirring cage shell anti-splash structure, which adds a first baffle 30 inside the connection port 15. The positional arrangement of the first baffle 30 can specifically intercept the snow shoveled by the snow-throwing blades 21, as well as some snow attempting to splash from the connection port 15 due to centrifugal force, allowing it to be smoothly thrown toward the snow outlet 16. This optimizes the snow's trajectory within the cylinder 12, reduces the possibility of snow splashing from the top and first side 13, reduces the impact on pedestrians and cleared areas, solves the defect of snow splashing easily during the operation of existing snowplows, effectively improves the snowplow's working efficiency, cleanliness, and safety, has a simple overall structure, requires no complex processing, has low manufacturing costs, is easy to install and maintain, and is suitable for widespread application.

[0036] In one embodiment, the first stop 30 has an outer arc surface, the center of which coincides with the center of the connection port 15, and the outer arc surface is fitted against the inner wall of the connection port 15. The design of the outer arc surface increases the contact area between the first stop 30 and the inner wall of the connection port 15, improving the connection strength. The first stop 30 can then more firmly withstand the impact of snow accumulation, reducing loosening or deformation caused by uneven stress, extending the service life of the first stop 30, and improving structural reliability.

[0037] Furthermore, the first stop 30 has an inner arc surface, the center of which coincides with the center of the connecting port 15.

[0038] The ratio of the width of the first stop 30 to the radius of the connection port 15 is in the range of 0.1 to 0.16. In this embodiment, the ratio is preferably 0.14. This structural design can effectively block snow from splashing to the top and sides without excessively reducing the channel area of ​​the connection port 15, ensuring that snow can enter the cylinder 12 normally.

[0039] In one embodiment, the splash-proof structure further includes a second stop 50, which is fixedly installed on the inner wall of the arc-shaped housing 11 and close to the first side 13. The second stop 50 extends along the length of the arc-shaped housing 11, and the bottom end of the second stop 50 is raised toward the front side of the arc-shaped housing 11. The height of the second stop 50 is higher than the height of the center of the connection port 15.

[0040] By adding a second baffle 50 inside the arc-shaped housing 11, the flow path of snow that is randomly splashed under the action of the stirring blades 40 and the snow-throwing blades 20 is blocked by the inclined second baffle 50 and guided into the interior of the arc-shaped housing 11. This allows the snow to flow more concentratedly towards the connection port 15 and the cylinder 12, making the process of snow entering the cylinder 12 smoother and more efficient, and preventing snow from splashing out from the top and the first side 13. The second baffle 50 and the first baffle 30 form a double protection, further reducing the possibility of snow splashing, effectively solving the problem that snow easily splashes from the top and the first side 13 when existing snowplows are working, and improving the overall anti-splash performance of the snowplow.

[0041] In one embodiment, the height of the second stop 50 is lower than the height of the highest point of the connection port 15. While preventing snow from splashing, the second stop 50 also provides ample space for snow to enter the connection port 15 and the cylinder 12, ensuring that snow does not obstruct entry into the connection port 15 and thus affect snow removal efficiency. This height design achieves a balance between preventing snow splashing and guiding snow, allowing it to be effectively guided and smoothly pass through the connection port 15 into the cylinder 12, guaranteeing the continuity and efficiency of the snowplow's operation.

[0042] In one embodiment, the second stop 50 is located above the first stop 30. This arrangement allows the second stop 50 and the first stop 30 to form vertically connected protective areas in space, without obstructing each other's protective paths.

[0043] In one embodiment, the top of the second stop 50 is provided with a mounting block 51, and the first stop 30 and the mounting block 51 are integrally formed. The mounting block 51 is fixed to the inner wall of the arc-shaped housing 11 by welding. The mounting block 51 provides a more stable installation method for the second stop 50. When the snowplow is working, the second stop 50 continuously withstands the impact of snow. By fixing the second stop 50 to the inner wall of the arc-shaped housing 11 with the mounting block 51, the connection strength between the second stop 50 and the housing is greatly increased, enabling it to remain stable in harsh working environments, ensuring long-term and effective anti-splash function, and improving the reliability and durability of the equipment.

[0044] In one embodiment, the angle between the mounting block 51 and the second stop block 50 is an obtuse angle. Since the bottom end of the second stop block 50 is raised towards the front, after snow hits the second stop block 50, it will be guided back into the arc-shaped housing 11 and flow towards the connection port 15, effectively preventing snow from splashing from the top.

[0045] This embodiment also provides a snowplow, including the aforementioned swivel cover shell anti-splash structure. Because it employs the aforementioned swivel cover shell anti-splash structure, it has the same working principle and technical effects as the swivel cover shell anti-splash structure in the above embodiments, and will not be described again here.

[0046] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
