Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, specifically relating to a snowplow auger blade assembly that is easy to disassemble. Background Technology

[0002] In the use of snowplows, their core working component—the auger (spiral blade assembly)—is highly susceptible to overload deformation or damage when encountering hard obstacles (such as ice or rocks). Traditional auger blade assembly designs suffer from one or more of the following technical limitations:

[0003] Traditional augers typically employ a welded or one-piece molded structure. When a section of a blade is damaged, it cannot be replaced individually; the entire auger assembly must be disassembled and sent back to the factory for repair, or the entire assembly must be replaced. This results in long maintenance cycles, high costs, and severely impacts the snowplow's uptime.

[0004] Even if some designs allow for disassembly, the connection methods are usually quite complex, potentially requiring specialized tools or multiple people working together. In cold, harsh outdoor working environments, rapid on-site repairs are almost impossible, causing significant inconvenience to users. Summary of the Invention

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a snow sweeper auger blade assembly that is easy to disassemble.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a snow sweeper auger blade assembly that is easy to disassemble, including a middle connecting part, two sets of side connecting parts and two sets of auger blade assemblies, the two sets of auger blade assemblies are arranged on the left and right sides of the middle connecting part, and the two sets of side connecting parts are arranged on the side of the two sets of auger blade assemblies away from the middle connecting part.

[0007] Preferably, the intermediate connecting part includes an intermediate shaft, the side connecting part includes a side shaft, and a connecting block is provided at both ends of the intermediate shaft and on the side of the side shaft near the auger blade assembly. A plug is provided on the side of the connecting block, and a screw hole perpendicular to the axis is opened on the plug.

[0008] Preferably, the auger blade includes a blade shaft, which is a hollow structure. A plug-in block is provided on both the left and right sides of the blade shaft. The plug-in block includes a blade connecting part and a shaft end connecting part. The blade connecting part is plugged and fixed inside the end of the blade shaft. The shaft end connecting part is provided with a sliding groove that cooperates with the plug-in block. The two sets of auger blades are connected between the middle connecting part and the side connecting part through the cooperation of the plug-in block and the connecting block.

[0009] Preferably, a pulley for driving rotation is provided at the middle position of the intermediate shaft of the intermediate connecting part.

[0010] Preferably, both ends of the blade shaft are formed into hexagons, and the blade connection part in the plug block has a hexagonal structure that matches it.

[0011] Preferably, after the plug-in block is connected to the connecting block, a locking screw is connected between the plug-in block and the slide groove.

[0012] The beneficial effects of this utility model are: the overall auger is decomposed into three independent modules: the middle connecting part, the two auger blade groups on both sides, and the side connecting part. This design allows for partial replacement. When any part (especially the vulnerable blade part) is damaged, there is no need to replace or repair the entire auger assembly, which greatly reduces maintenance costs and downtime.

[0013] By setting an insert block on the connecting block and a corresponding sliding groove on the insert block of the blade shaft, the auger blades can be quickly disassembled by loosening the locking screws when they are damaged, which greatly reduces maintenance costs and downtime.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A snowplow auger blade assembly that is easy to disassemble, such as... Figures 1-2 As shown, it includes a middle connecting part, two sets of side connecting parts and two sets of auger blades. The two sets of auger blades are located on the left and right sides of the middle connecting part, and the two sets of side connecting parts are located on the side of the two sets of auger blades that is away from the middle connecting part.

[0019] The intermediate connecting part includes an intermediate shaft, and the side connecting part includes a side shaft. A connecting block is provided at both ends of the intermediate shaft and on the side of the side shaft near the auger blade assembly. A plug is provided on the side of the connecting block, and a screw hole perpendicular to the axis is opened on the plug.

[0020] The auger blades include a blade shaft, which is a hollow structure. A plug-in block is provided on both the left and right sides of the blade shaft. The plug-in block includes a blade connecting part and a shaft end connecting part. The blade connecting part is plugged and fixed inside the end of the blade shaft. The shaft end connecting part has a sliding groove that cooperates with the plug-in block. The two sets of auger blades are connected between the middle connecting part and the side connecting part through the cooperation of the plug-in block and the connecting block.

[0021] A pulley for driving rotation is provided at the middle position of the intermediate shaft of the intermediate connecting part.

[0022] Both ends of the blade shaft are formed into hexagons, and the blade connection part in the plug block has a hexagonal structure that matches it.

[0023] After the plug-in block is connected to the connecting block, a locking screw is connected between the plug-in block and the slide groove.

[0024] The principle of this utility model is to decompose the entire auger into three independent modules: the middle connecting part, the two auger blade groups on both sides, and the side connecting part. The overall structure is installed on the machine body through the two side connecting parts. This design allows for partial replacement. When any part (especially the vulnerable blade part) is damaged, there is no need to replace or repair the entire auger assembly, which greatly reduces maintenance costs and downtime.

[0025] Insertion blocks are set on the connecting blocks, and sliding grooves are set on the insertion blocks of the blade shafts to match them. This design allows each module to automatically and accurately align and position itself during assembly, effectively ensuring the concentricity of the entire auger after assembly and avoiding vibration problems during operation.

[0026] Both the blade shaft end and the interior of the connector block are hexagonal, a design that ensures torque can be effectively and without slippage, providing strong torsional resistance.

[0027] After the insert block mates with the slide groove, it is finally tightened by a locking screw. This screw is installed perpendicular to the axis and serves to prevent axial loosening and strengthen radial shear. The structure is simple and reliable.

[0028] The entire disassembly and installation process requires no special tools or complex equipment; it can be completed with just a regular wrench. This makes it possible to perform rapid repairs at cold outdoor work sites, significantly improving equipment uptime and user experience.

[0029] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
