Description

Technical Field

[0001] This utility model relates to the field of snow shield technology, and in particular to a multi-angle adjustable snow shield. Background Technology

[0002] In cold regions, people often need to clear snow. Manual snow removal is inefficient and laborious, so a device that uses rotating brush wheels to clear snow from the road is needed. The device mainly drives a cylindrical brush to rotate, sweeping the snow off the road. By tilting at a certain angle, the snow is thrown to the side of the road. To prevent snow from splashing during the throwing process, snow deflectors are usually installed at the back of the device, which can effectively reduce the amount of snow and lighten the cleaning burden.

[0003] For example, an improved structure of a snow removal roller brush snow deflector, disclosed in CN217974205U, uses an extended snow deflector mechanism to fix the extended plate to the slide rail using a snap-fit ​​block and a snap-fit ​​groove. This allows for adjustment of the deflector length, increasing the adjustability of the snow removal roller brush snow deflector during use. The buffer adjustment mechanism allows for adjustment of the deflector's flipping buffer degree according to actual usage requirements.

[0004] The aforementioned existing technologies still have some shortcomings in use:

[0005] 1. Firstly, the extension plate of the prior art is fixed by a snap-fit ​​block and a snap-fit ​​groove. However, when the prior art is in use, rain and snow will exert a force on the extension plate, causing the extension plate to tend to move outward. That is, the extension plate may move with the snap-fit ​​block, which may cause the snap-fit ​​block to disengage from the snap-fit ​​groove, causing the extension plate to detach from the baffle. In other words, the extension plate of this design has a potential risk of detachment during operation.

[0006] 2. Although the existing technology includes a cleaning mechanism, the cleaning device focuses on removing snow and dust from the inner wall of the housing, neglecting the cleaning needs of the baffles and extension plates. Furthermore, the process relies on manual intervention; if cleaning is required during operation, work must be stopped.

[0007] Therefore, the aforementioned existing technologies still have room for improvement. Utility Model Content

[0008] To address the aforementioned problems, this invention provides a multi-angle adjustable snow shield.

[0009] A multi-angle adjustable snow shield includes a snow shield housing. A baffle is hinged to the outside of the snow shield housing via a hinge. Two fixed brackets are symmetrically arranged on the side of the baffle near the snow shield housing. A rotating shaft is rotatably passed through the fixed bracket. An adjusting rod is rotatably installed on one side of the rotating shaft. An adjusting bracket is installed on the snow shield housing at the position corresponding to the fixed bracket. The side of the adjusting rod away from the fixed bracket is connected to the adjusting bracket via an adjusting component.

[0010] The rotating shaft is threaded with a fixing nut on the side opposite to the adjusting rod, and the fixing nut is fastened to the fixing bracket to fix the adjusting rod.

The side wall of the rotating shaft is provided with a positioning hole for the positioning rod to be inserted. When the fixing nut is tightened on the side wall of the fixing bracket, the positioning hole is aligned with the limiting hole so that the positioning rod can be smoothly inserted into the positioning hole.

[0012] Preferably, the adjusting rod has a transverse sliding hole, and the transverse sliding hole has locking holes at equal intervals.

[0013] Preferably, the adjusting component includes a locking shaft mounted on the adjusting bracket, the locking shaft passing through a transverse sliding hole and threadedly connected to a locking nut, the locking nut being fastened to the side wall of the adjusting rod by a washer.

[0015] Preferably, the adjusting rod extends to the side away from the fixed bracket with an adjusting handle, and the adjusting handle extends obliquely in the direction away from the snow deflector shell.

[0016] Preferably, side plates are provided on both sides of the concave surface of the baffle.

[0017] Preferably, a guide plate is provided on the side of the baffle away from the snow deflector shell.

[0018] Preferably, the guide plate extends obliquely along the direction away from the concave surface of the snow deflector shell.

[0019] Preferably, the guide plate and the baffle are detachably connected.

[0023] II. The baffle of this utility model, by setting an extension plate and adopting a T-shaped strip and sliding groove design, and cooperating with a micro motor drive, realizes the flexible extension and retraction adjustment of the snow baffle, which can quickly adapt to different snow volume requirements. The guide plate at the front end of the extension plate accelerates the snow sliding down and enhances the overall drainage effect.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figures 1-9 The embodiments of this utility model will be described in detail below.

[0037] Example 1:

[0038] Reference Figures 1 to 3 As shown, a multi-angle adjustable snow shield includes a snow shield housing 1. A baffle 10 is hinged to the outside of the snow shield housing 1 via a hinge. Two fixed brackets 101 are symmetrically arranged on the side of the baffle 10 near the snow shield housing 1. A rotating shaft 102 is rotatably passed through the fixed bracket 101. An adjusting rod 103 is rotatably installed on one side of the rotating shaft 102. An adjusting bracket 104 is installed on the snow shield housing 1 at the position corresponding to the fixed bracket 101. The side of the adjusting rod 103 away from the fixed bracket 101 is connected to the adjusting bracket 104 via an adjusting component.

[0039] A fixing nut 105 is threadedly connected to the side of the rotating shaft 102 away from the adjusting rod 103. The fixing nut 105 is fastened to the fixing bracket 101 to fix the adjusting rod 103.

[0040] The outer wall of the fixing nut 105 is provided with a limiting hole 106, and a positioning rod 107 is provided inside the limiting hole 106. The side wall of the rotating shaft 102 is provided with a positioning hole 108 for the positioning rod 107 to be inserted. When the fixing nut 105 is fastened to the side wall of the fixing bracket 101, the positioning hole 108 is aligned with the limiting hole 106 so that the positioning rod 107 can be smoothly inserted into the positioning hole 108.

[0041] The adjusting rod 103 has a horizontal sliding hole 109, and the horizontal sliding hole 109 has locking holes 110 at equal intervals.

[0042] The adjusting component includes a locking shaft 111 mounted on the adjusting bracket 104. The locking shaft 111 passes through the transverse sliding hole 109 and is threadedly connected to a locking nut 112. The locking nut 112 is fastened to the side wall of the adjusting rod 103 by a washer 113.

[0043] The diameter of the locking shaft 111 is smaller than the diameter of the locking hole 110.

[0044] An adjustment handle 114 extends from the side of the adjustment rod 103 away from the fixed bracket 101, and the adjustment handle 114 extends obliquely in the direction away from the snow shield housing 1.

[0045] In the specific implementation process, the position of the adjusting rod 103 is adjusted by rotating the adjusting handle 114, which drives the rotating shaft 102 to rotate on the fixed bracket 101, so as to realize the multi-angle adjustment of the baffle 10. When the appropriate angle is reached, the fixing nut 105 is tightened until the fixing nut 105 is tightly attached to the side wall of the fixed bracket 101, and the positioning rod 107 is inserted into the positioning hole 108 to limit the rotation of the adjusting rod 103 and ensure that the baffle 10 is stable.

[0046] Simultaneously, when the adjusting handle 114 rotates the adjusting rod 103, the locking shaft 111 moves from the locking hole 110 into the transverse sliding hole 109. Then, the adjusting handle 114 drives the adjusting rod 103 to move, that is, the locking shaft 111 slides in the transverse sliding hole 109. When the baffle 10 is adjusted to a suitable angle, the locking hole 110 is aligned with the locking shaft 111. Tighten the locking nut 112 to ensure that the locking shaft 111 is accurately aligned and locked in the locking hole 110, further stabilizing the position of the baffle 10 and ensuring safe use.

[0047] Through the above structural design, the snow barrier not only achieves multi-angle adjustment but also has high stability, making it suitable for different snowfall environments, effectively preventing snow intrusion, and improving ease of use and safety.

[0048] In addition, the above design ensures that the baffle 10 can be firmly fixed at any angle through the dual locking mechanism of the fixing nut 105 and the locking nut 112, avoiding displacement caused by wind or other external forces, and further enhancing the practicality and reliability of the snow baffle.

[0049] In addition, the locking nut 112 and the washer 113 cooperate to ensure the stability of the locking shaft 111 and prevent loosening.

[0050] The tilted design of the adjustment handle 114 facilitates operation and improves adjustment efficiency. The adjustment handle 114 is made of non-slip material, providing a comfortable grip and easy operation. The surface coating of the adjustment bracket 104 is rust-proof and wear-resistant, extending its service life.

[0051] Preferably, side plates 115 are provided on both sides of the concave surface of the baffle 10. The side plates 115 are made of high-strength materials to enhance the overall structural stability. The inner side of the side plates 115 is provided with a buffer pad to effectively reduce the impact of snow accumulation and further improve the protective performance of the snow baffle. The connection between the side plates 115 and the baffle 10 is reinforced to ensure that it will not deform after long-term use and can adapt to various harsh weather conditions.

[0052] A deflector 116 is provided on the side of the baffle 10 away from the snow deflector housing 1. The deflector 116 extends obliquely along the concave surface away from the snow deflector housing 1. The design of the deflector 116 can effectively guide snow to slide off, reduce snow accumulation, and improve the working efficiency of the snow deflector. The surface of the deflector 116 is smooth, which can effectively reduce wind resistance and keep it as stable as a mountain in the wind, ensuring stability even in strong wind conditions.

[0053] The deflector 116 and the baffle 10 are detachable, which facilitates daily maintenance and replacement and ensures long-term performance.

[0054] Example 2:

[0055] See Figures 4 to 7 As shown, based on Embodiment 1, this application further optimizes the design of the baffle 10, that is, the baffle 10 is slidably provided with an extension plate 20 on its concave surface. The extension plate 20 extends along the width direction of the baffle 10 and its length can be flexibly adjusted according to the actual snow volume requirements to enhance the snow blocking effect.

[0056] The extension plate 20 is provided with multiple T-shaped strips 201 at equal intervals on the side facing the baffle 10. The baffle 10 is provided with a sliding groove for the T-shaped strips 201 to slide. The T-shaped strips 201 are tightly fitted with the sliding groove to ensure that the extension plate 20 is stable and adjustable. Anti-slip texture is added to the surface of the extension plate 20 to improve the efficiency of snow drainage.

[0057] A protective cover 202 is provided on the baffle 10 at the chute. The protective cover 202 can prevent snow from accumulating in the chute, ensure the smooth sliding of the T-shaped strip 201, and allow the extension plate 20 to be adjusted freely. The protective cover 202 is made of low-temperature resistant material, has strong impact resistance, and is suitable for extreme weather, further improving the durability and reliability of the snow baffle.

[0058] The front end of the extension plate 20 is also equipped with a deflector plate 116 to accelerate the sliding of snow and enhance the overall drainage effect.

[0059] The baffle 10 is provided with a driving device for driving the extension plate 20 to slide. Specifically, the driving device includes a driving box 203 located on the upper surface of the baffle 10. The driving box 203 has a built-in micro motor (not shown in the figure) as a power source.

[0060] A plurality of drive shafts 204 are rotatably mounted on the baffle 10 below the drive box 203. The drive shafts 204 rotatably pass through the baffle 10. The upper ends of the drive shafts 204 are all located inside the drive box 203, and adjacent drive shafts 204 are connected by sprockets and chains to form a transmission system. A micro motor inside the drive box 203 is connected to one of the drive shafts 204. When the micro motor starts, it drives the drive shaft 204 to rotate and transmits power through the sprockets and chains.

[0061] A gear 205 is installed at the lower end of the drive shaft 204, which passes through the extension plate 20. The gear 205 meshes with a rack 206 at the bottom of the extension plate 20. A micro motor drives the drive shaft 204 to rotate, and the gear 205 drives the rack 206 to move, ensuring the smooth extension and retraction of the extension plate 20 to flexibly adapt to different snow-blocking needs. A guide groove 207 is provided on the extension plate 20 along the length of the rack 206 for the drive shaft 204 to slide, ensuring that the extension plate 20 does not interfere with the drive shaft 204 during extension and retraction, maintaining smooth operation. A lubrication device is installed in the guide groove 207 to reduce friction, extend service life, and ensure efficient operation even in low-temperature environments.

[0062] The lubrication system uses a specially formulated low-temperature lubricant to ensure good lubrication even in extremely cold conditions, preventing lubrication failure due to low temperatures and further improving the working stability of the snow shield in harsh environments.

[0063] A protective shell 208 is provided at the lower end of the extension plate 20 corresponding to the rack 206. The protective shell 208 is made of high-strength material, which effectively prevents snow and debris from entering, ensures normal meshing of the rack 206 and the gear 205, and extends the service life.

[0064] In summary, the baffle 10 of this application, by setting an extension plate, adopting a T-shaped strip 201 and a sliding groove design, and cooperating with a micro motor drive, achieves flexible extension and retraction adjustment of the snow baffle, which can quickly adapt to different snow volume requirements. The guide plate 116 at the front end of the extension plate 20 accelerates the sliding of accumulated snow and enhances the overall drainage effect.

[0065] Example 3:

[0066] See Figure 8 and Figure 9 As shown, based on Embodiment 1 or Embodiment 2, the extension plate 20 is further optimized. The added snow removal device can effectively scrape the snow accumulated on the lower surface of the extension plate 20 and the baffle 10, keep the surface clean, and improve the drainage efficiency.

[0067] Specifically, the snow removal device includes a snow removal plate 209 slidably disposed on the lower surface of the extension plate 20. The two ends of the snow removal plate 209 are fixed to the side plates 115 on both sides of the baffle 10. The snow removal plate 209 is constructed with an inverted triangular cross-section, and the upper surface of the snow removal plate 209 is in close contact with the lower surface of the extension plate 20 to ensure the snow removal effect. The snow removal plate 209 is made of high hardness and wear-resistant material, which is suitable for frequent snow removal operations. The upper surface of the snow removal plate 209 is provided with a lubricating coating to reduce frictional resistance and improve snow removal efficiency.

[0068] The snowplow 209 has several snow-breaking teeth 210 evenly distributed along its length on both sides. The snow-breaking teeth 210 are serrated and can quickly break up snow, prevent snow accumulation, and ensure that the snowplow 209 slides smoothly.

[0069] Meanwhile, the snow removal plate 209 is equipped with a heating device inside. The heating device is in close contact with the snow removal plate 209 through a heat-conducting material, ensuring that it can effectively melt snow in low-temperature environments, prevent freezing, and further improve the snow removal effect.

[0070] The side of the extension plate 20 away from the guide plate 116 is also equipped with several snow-breaking teeth 210. The snow-breaking teeth 210 are distributed in a sawtooth pattern, which can effectively cut the snow and ice on the lower surface of the baffle 10, ensuring that the snow baffle remains clean during the extension and retraction process, and improving the overall snow removal efficiency.

[0071] Meanwhile, a heating device is also installed on the side of the extension plate 20 opposite to the guide plate 116. This device, through a heat-conducting material in close contact with the extension plate 20, ensures effective melting of snow and ice under extremely cold conditions, preventing icing and further guaranteeing the smoothness and efficiency of the snow barrier's extension and retraction, thus improving the overall snow removal effect. The heating device employs an intelligent temperature control system that automatically adjusts the heating power according to the ambient temperature, ensuring efficient energy utilization and extending the equipment's service life.

[0072] It should be noted that the snowplow plate 209 has a through hole for the protective shell 208 to pass through. The protective shell 208 slides in contact with the snowplow plate 209 through the through hole, ensuring that the protective shell 208 does not interfere with the operation of the snowplow plate 209 during the sliding process.

[0073] In summary, by setting up the snow removal plate 209 and utilizing the sliding and telescopic relationship between the extension plate 20 and the baffle 10, this application can effectively scrape away the snow accumulated on the lower surface of the extension plate 20 and the lower surface of the baffle 10, keep the surface clean, improve the drainage efficiency, ensure the stable operation of the equipment in severe weather, and extend its service life.
