Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, specifically relating to a snowplow auger. Background Technology

[0002] Winter snow accumulation causes great inconvenience to vehicles and pedestrians, and can even cause traffic accidents. To facilitate travel, people have created a variety of snow removal machines or devices. For example, a snowplow includes an auger snow collection device connected to the engine via a transfer case. The output shaft of the transfer case is connected to the auger frame, which drives the auger frame to rotate. The blades on the auger frame collect the snow during rotation and throw it out through the throwing head on the base of the snowplow, thereby achieving the purpose of snow removal.

[0003] However, this type of auger snow collection device requires blade replacement after prolonged use because its edges come into contact with the ground during use. The auger is usually formed by spirally bending a single piece of steel bar and is an integral structure with the central drive shaft. Therefore, when replacing it, the drive shaft needs to be completely removed from the housing and the entire auger assembly needs to be replaced, resulting in high costs. In addition, it is more complicated to disassemble the entire auger assembly than to disassemble the entire auger assembly. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a snow sweeper auger.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A snow sweeper auger includes a rotating shaft, a middle connecting plate at the middle position of the rotating shaft, and a side connecting plate at each end of the rotating shaft. A stamped groove is provided in the middle position of the middle connecting plate, the stamped groove is bent downwards, and the rotating shaft is embedded in the stamped groove. The middle connecting plate on the front side of the rotating shaft is a front connecting part, and the middle connecting plate on the rear side of the rotating shaft is a rear connecting part. A middle folding connecting ear is provided on both the left and right sides of the front and rear connecting parts. The two middle folding connecting ears in the front connecting part are folded upwards, and the two middle folding connecting ears in the rear connecting part are folded upwards. The middle folding connecting ear folds downwards; both the upper and lower ends of the side connecting plate are provided with a side folding connecting ear. The upper side folding connecting ear is located on the front side of the top of the side connecting plate, and the lower side folding connecting ear is located on the rear side of the bottom of the side connecting plate. A first auger blade and a second auger blade are connected between the two side connecting plates and the middle connecting plate. The first auger blade is connected between the upper side folding connecting ear in the side connecting plate and the middle folding connecting ear on the rear side of the middle connecting plate. The second auger blade is connected between the lower side folding connecting ear in the side connecting plate and the middle folding connecting ear on the front side of the middle connecting plate.

[0006] Preferably, a pin slot is formed by stamping at the middle position of the side connecting plate, and a pin hole is provided in the stamping groove at the middle position of the middle connecting plate.

[0007] Preferably, the rotating shaft is provided with three fixing pins, which are respectively located at the corresponding positions of the middle connecting plate and the side connecting plate. The fixing pins on both sides are engaged in the pin slots of the side connecting plate, and the middle fixing pin is fixed in the pin hole of the middle stamping groove.

[0008] Preferably, the middle folding connecting ear, the side folding connecting ear, the first auger blade, and the second auger blade are each provided with two connecting holes that can cooperate with each other.

[0009] The beneficial effects of this utility model are as follows: By setting an intermediate connecting plate and a side connecting plate, and setting an intermediate folding connecting ear and a side folding connecting ear on the intermediate connecting plate and the side connecting plate respectively, the auger blades are connected by the intermediate folding connecting ear and the side folding connecting ear. When the auger blades need to be repaired or replaced, they can be replaced simply by removing the auger blades from the intermediate connecting plate and the side connecting plate. There is no need to disassemble the entire auger assembly, which can effectively reduce the maintenance cost and further improve the convenience of disassembly and assembly.

[0010] By setting a middle folding connecting ear and a side folding connecting ear, the bending angle of both can further conform to the curvature of the auger blade, thereby improving the installation strength of the auger blade. Attached Figure Description
