A solid vane auger assembly

Abstract

An integral blade auger assembly belongs to the field of snowplow technology. By stamping a folding connecting plate at the middle position of the auger blade, and connecting the folding connecting plate to the intermediate connecting sleeve on the rotating shaft, the rigidity of the middle part of the auger blade can be increased, avoiding vibration and providing a better operating environment for the user. At the same time, by setting a tie rod, the outer end of the auger blade is connected to the folding connecting plate, so that the tie rod holds the outer edge of the middle of the auger blade, forming a triangular stable structure. This gives the middle position of the auger blade strong rigidity when it comes into contact with snow, thus facilitating the snow-rolling and further reducing vibration and noise.

Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, specifically relating to an integral blade auger assembly. 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] To improve snow removal efficiency, augers typically increase the width of their blades, allowing them to contact more snow during rotation. However, this increased blade width also causes greater vibration at the edges of the blades furthest from the connection point due to reduced rigidity. This vibration generates significant noise during snow removal, affecting operation. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide an integral blade auger assembly.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an integral blade auger assembly, including a rotating shaft, an intermediate connecting sleeve provided in the middle of the rotating shaft, a side connecting sleeve provided at each end of the rotating shaft, two auger blades connected between the two side connecting sleeves, the two ends of the auger blades connected to the side connecting sleeves on both sides, and the middle part of the auger blades connected to the intermediate connecting sleeve.

[0006] A folded connecting plate is stamped in the middle of the auger blade toward the rotating shaft. The middle of the auger blade is riveted to the connecting plate on the middle connecting sleeve through the folded connecting plate.

[0007] A connecting hole is provided on the auger blade on the outer side of the folding connecting plate. A pull plate is connected between the connecting hole and the folding connecting plate, and the pull plate is riveted between the connecting hole and the folding connecting plate.

[0008] Preferably, both the intermediate connecting sleeve and the side connecting sleeve include a sleeve fitted on the rotating shaft and two symmetrically arranged connecting plates. The sleeve has a mating pin hole, and the corresponding rotating shaft has a positioning pin hole. The positioning pin hole has a positioning pin for inserting into the mating pin hole in the sleeve to fix the position of the sleeve.

[0009] Preferably, the left and right sides of the auger blade are symmetrically twisted forward along the folding connecting plate and a connecting ear is formed at the end. The connecting ears on both sides are riveted to the connecting plate in the side connecting sleeve.

[0010] Preferably, the auger blades are stamped with reinforcing ribs that run through both the left and right ends.

[0011] The beneficial effects of this utility model are as follows: by stamping and forming a folded connecting plate in the middle position of the auger blade, and connecting the folded connecting plate with the middle connecting sleeve on the rotating shaft, the rigidity of the middle part of the auger blade can be increased, vibration can be avoided, and the user can have a better operating environment.

[0012] Meanwhile, by setting up a tie rod, the outer end of the auger blade is connected to the folding connecting plate, so that the tie rod holds the outer edge of the middle of the auger blade, forming a triangular stable structure. This allows the middle position of the auger blade to have strong rigidity when it comes into contact with snow, thus making it easier to roll up the snow and further reducing the generation of vibration and noise.
