Description

Technical Field

[0001] The present application relates to the technical field of snowplows, and in particular to a reinforced snowplow blade structure and a snowplow. Background Art

[0002] Snowplows are important equipment for snow removal in winter. When working, snowplows usually gather snow on the road with a snow scraper, and then use a snow throwing paddle to throw the gathered snow to an area far away from the road. Snowplows in the prior art mainly have the following defects: the snow roller is easily bent and deformed when the snow is thrown, resulting in poor snow throwing effect; the area ratio between the snow throwing part and the snow twisting part of the snow roller is not appropriate, resulting in a large snow throwing load, resulting in the snow not being thrown far. For the traditional snow scraper structure, reference can be made to a snowplow auger proposed in Publication No. CN219731827U.

[0003] Based on the above technical problems, publication number CN115262463A provides a snow roller assembly and a snow sweeper. Specifically, on the basis of a traditional snow scraper, the snow scraper is configured as a multi-section structure, and a connecting portion is provided at the end of each blade section. The innermost blade is fixedly connected to the snow throwing paddle, so that both ends of each blade section are effectively fixed, avoiding the problem of bending deformation caused by a long span, and improving the structural strength of the snow roller assembly.

[0004] Please refer to the attached patent for details. Figure 4 It can be seen that it adopts a segmented combination method to form a group of snow scraper components, which will require abandoning the traditional snow scraper for re-molding and testing. In view of this, how to improve the technology of the traditional snow scraper structure so that it can improve the overall strength and improve the snow throwing efficiency in a more convenient and low-cost manner is the purpose of this application. Summary of the invention

[0005] Based on this, the present application provides a reinforced snow-clearing blade structure and a snow-clearing machine for improvement.

[0006] The technical solution adopted by the present application to solve its technical problems is: a reinforced snow-clearing blade structure, comprising: a drive shaft; a snow-throwing paddle installed in the middle of the drive shaft and configured to rotate synchronously with the drive shaft; a snow scraper group symmetrically arranged on both sides of the snow-throwing paddle and connected to the drive shaft for synchronous rotation.

[0007] The snow scraper assembly includes a first blade and a second blade which are separate from each other, and the first blade and the second blade are spirally wound around the driving shaft along the axial direction of the driving shaft;

[0008] The snow scraper assembly also includes a reinforcing connecting piece and a fixing connecting piece for connecting the first blade and the second blade;

[0009] The middle end of the reinforcing connecting piece is fixedly connected to the driving shaft, and the two ends thereof are respectively fixedly connected to the middle positions of the first blade and the second blade, and at least a part thereof is kept in contact with the arc surface of the first blade and the second blade;

[0010] The middle end of the fixed connecting piece is fixedly connected to the driving shaft, and the two ends of the fixed connecting piece are respectively fixedly connected to the outer ends of the first blade and the second blade.

[0011] In some embodiments, the inner ends of the first blade and the second blade are connected to the snow throwing paddle. Preferably, two bolts are used for fastening.

[0012] In some embodiments, the snow throwing paddle is substantially flat, and the inner ends of the first blade and the second blade have a straight extension portion, and the extension portion is connected to the snow throwing paddle via a fastener.

[0013] In some embodiments, the maximum spacing between the extensions of the two symmetrically arranged first blades or the two symmetrically arranged second blades is 100-300 mm. As a preference, the preferred spacing is 170 mm.

[0014] In some embodiments, a rubber plate for connecting the extensions of the two symmetrically arranged first blades and between the two symmetrically arranged second blades is provided, and the rubber plate is attached to the snow throwing paddle.

[0015] In some embodiments, the distance between the outermost end of the snow scraper assembly and the drive shaft is 50-200 mm, and preferably 87.5 mm.

[0016] In some embodiments, the reinforcing connecting piece is in a spiral structure, wherein the end thereof has an embracing portion which is at least partially sleeved on the drive shaft, the maximum width of the reinforcing connecting piece is 20-65 mm, and the included angle of the side extension line is 15-45°. Preferably, the embracing portion is a semi-open structure, the maximum width of the reinforcing connecting piece is 43.5, and the included angle of the side extension line is 30-35°

[0017] In some embodiments, viewed in the unfolded orthographic projection direction of the snow throwing paddle, the first blade and the second blade have an intersection, the reinforcing connecting piece is installed on the driving shaft to form a connection point, and the distance between the intersection and the connection point is 0-20 mm. Preferably, it is best to keep the intersection and the connection point coincident, so that the structural stability and balance are better.

[0018] In some embodiments, the angle between the side extension lines of the two symmetrically arranged first blades is 20-90°, as viewed in the unfolded orthographic projection direction of the snow throwing paddle. Preferably, the angle spacing is 20-60°. This helps to guide the scraped snow into the fixed angle and to the snow throwing bucket.

[0019] Another aspect of the present application provides a snowplow, comprising the reinforced snowplow blade structure described in any one of the above embodiments.

[0020] Specifically: the snowplow includes a snowplow bucket and a snow throwing bucket. The inner wall of the snowplow bucket is provided with a guide channel. The snow throwing bucket is communicated with the guide channel. The reinforced snowplow blade structure is installed in the snowplow bucket to gather the accumulated snow from both sides of the snowplow bucket to the middle area and throw it to the mouth of the snow throwing bucket through the guide channel.

In this way, the guide channel can guide the snow scraped by the snow throwing paddle into the fixed angle and guide it to the snow throwing bucket. The fixed angle is preferably greater than or equal to 20 degrees and less than or equal to 60 degrees, so that the guide channel can gradually guide the snow with a larger lateral width to a range with a smaller lateral width, and then concentrate the snow throwing.

Specifically, through the carefully designed reinforced snow-sweeping blade structure, not only the stability of the overall structure is improved, and the problem of easy deformation of the snow scraper during high-intensity operation is effectively solved, but also by optimizing the blade layout and connection method, the snow gathering and throwing mechanism is improved in some aspects, thereby greatly improving the snow throwing efficiency.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0032] Reference Figure 1-6 As shown, a reinforced snow-clearing blade structure is provided, comprising: a drive shaft 1; a snow-throwing paddle 2, installed in the middle of the drive shaft 1 and configured to rotate synchronously with the drive shaft 1; and a snow scraper group 3, symmetrically arranged on both sides of the snow-throwing paddle 2, and connected to the drive shaft 1 for synchronous rotation.

[0033] The snow scraper assembly 3 includes a first blade 31 and a second blade 32 which are separate from each other, and both of them are spirally wound around the driving shaft 1 along the axial direction of the driving shaft 1;

[0034] The snow scraper assembly 3 further includes a reinforcing connecting piece 33 and a fixing connecting piece 34 for connecting the first blade 31 and the second blade 32;

[0035] The middle end of the reinforcing connecting piece 33 is fixedly connected to the driving shaft 1, and the two ends thereof are respectively fixedly connected to the middle positions of the first blade 31 and the second blade 32, and at least a part thereof is kept in contact with the arc surface of the first blade 31 and the second blade 32;

[0036] The middle end of the fixed connecting piece 34 is fixedly connected to the driving shaft 1 , and the two ends thereof are fixedly connected to the outer ends of the first blade 31 and the second blade 32 , respectively.

[0037] In some embodiments, the inner ends of the first blade 31 and the second blade 32 are connected to the snow throwing paddle 2. Preferably, two bolts are used for fastening.

[0038] The snow throwing paddle 2 is roughly flat, and the inner ends of the first blade 31 and the second blade 32 have a straight extension portion 35, and the extension portion 35 is connected to the snow throwing paddle 2 through a fastener.

[0039] In some embodiments, the maximum spacing L1 of the extensions 35 of the two symmetrically arranged first blades 31 or the two symmetrically arranged second blades 32 is 100-300 mm. As a preference, the preferred spacing is 170 mm.

[0040] In some embodiments, a rubber plate 4 for connecting the extensions 35 of the two symmetrically arranged first blades 31 and the two symmetrically arranged second blades 32 is provided, and the rubber plate 4 is attached to the snow throwing paddle 2. In this way, it plays a role of shock absorption and support. In addition, in order to optimize the snow sweeping effect and reduce noise, acoustic shock absorption materials can be incorporated into the design of the rubber plate 4, which not only realizes the basic functions of physical connection and shock absorption support, but also effectively absorbs the vibration and noise generated during operation, thereby improving the user experience.

[0041] In some embodiments, the distance L2 between the outermost end of the snow scraper group 3 and the drive shaft 1 is 50-200 mm. Preferably, the preferred distance is 87.5 mm. This can be applied to most snow sweeping needs.

[0042] In some embodiments, the reinforcing connecting piece 33 is in a spiral structure, wherein the end thereof has an embracing portion 331 which is at least partially sleeved on the drive shaft 1, the maximum width W1 of the reinforcing connecting piece 33 is 20-65 mm, and the angle of the side extension line thereof is 15-45°. Preferably, the embracing portion 331 is a semi-open structure, the maximum width W1 of the reinforcing connecting piece 33 is 43.5, and the angle α of the side extension line thereof is 30-35°. In this way, it can be effectively connected with the first blade 31 and the second blade 32 to improve the rigidity of the overall structure. For the design of the reinforcing connecting piece 33, considering that it plays an important role in structural reinforcement, it is preferred to use a high-strength alloy material, such as an aluminum alloy or a titanium alloy, to ensure that it will not deform or break when subjected to a large snow load. The spiral structure not only increases the contact area with the drive shaft 1 and improves the stability of the connection, but also ensures a more uniform stress distribution through the accurately calculated angle of the side extension line, further enhancing the mechanical properties of the overall structure.

[0043] For the fixed connecting piece 34, it is crucial to select a material with the same high strength characteristics. Considering that it is directly connected to the outer end of the blade and is subject to a large dynamic load, it is recommended to use thickened stainless steel material and perform edge reinforcement treatment to prevent fatigue fracture under extreme working conditions.

[0044] Reference Figure 3 As shown, in the unfolded orthographic projection direction of the snow throwing paddle 2, the first blade 31 and the second blade 32 have an intersection, the reinforcing connecting piece 33 is installed on the driving shaft 1 to form a connection point, and the distance L3 between the intersection and the connection point is 0-20 mm. Preferably, it is best to keep the intersection and the connection point coincident, so that the structural stability and balance are better.

[0045] Continue to refer to Figure 3 As shown, in some embodiments, the angle β between the side extension lines of the two symmetrically arranged first blades 31 is 20-90°, as viewed in the unfolded orthographic projection direction of the snow throwing paddle 2. Preferably, the angle spacing is 20-60°. This helps to guide the scraped snow into the fixed angle and to the snow throwing bucket 6.

[0046] Another aspect of the present application provides a snowplow, comprising the reinforced snowplow blade structure described in any one of the above embodiments.

[0047] Specifically: the snowplow includes a snowplow hopper 5 and a snow throwing bucket 6. The inner wall of the snowplow hopper 5 is provided with a guide channel 7. The snow throwing bucket 6 is communicated with the guide channel 7. The reinforced snowplow blade structure is installed in the snowplow hopper 5 to gather the accumulated snow from both sides of the snowplow hopper 5 to the middle area and throw it to the mouth of the snow throwing bucket 6 through the guide channel 7.

[0048] Based on the above snow sweeper, in some embodiments, viewed from the unfolded orthographic projection direction of the snow throwing paddle 2, the guide channel 7 includes two guide walls 71, the included angle γ of the extension line of the guide wall 71 is 20-90°, and the included angle of the side extension line of the two symmetrically arranged first blades 31 and the included angle of the extension line of the guide wall 71 are set to maintain a difference of ±10°. In this way, the guide channel 7 can guide the snow scraped by the snow throwing paddle 2 into the fixed angle and guide it to the snow throwing bucket 6. The fixed angle is preferably greater than or equal to 20 degrees and less than or equal to 60 degrees, so that the guide channel 7 can gradually guide the snow with a larger lateral width to a range with a smaller lateral width, and then concentrate the snow throwing.

[0049] Reference Figure 6As shown, based on the above-mentioned snowplow, in some embodiments, viewed from the rotation axis direction of the drive shaft 1, the distance L4 from the drive shaft 1 to the outer edge of the side wall of the snowplow 5 is 100-300mm, and the distance L5 from the drive shaft 1 to the entrance of the snow throwing bucket 6 is 100-500mm.

[0050] In the embodiment, in order to further enhance the durability and wear resistance of the snow scraper set 3, the first blade 31 and the second blade 32 can be made of highly wear-resistant materials, such as hardened steel or nickel-containing alloy, to ensure that good snow scraping efficiency can be maintained under long-term use. At the same time, the surface can be specially treated, such as chrome plating or spraying wear-resistant coating, to increase its service life in harsh environments.
