Description

Technical Field

[0001] The present application relates to the field of material transportation, and in particular to a spiral blade of a conveyor auger. Background Art

[0002] At present, auger conveyors, also known as screw conveyors, are widely used in various industries. Their working principle is that the rotating spiral blades push the material to transport it. They are suitable for horizontal or inclined conveying of powdery, granular and small block materials, but are not suitable for conveying perishable, sticky, and easily agglomerated materials.

[0003] Auger conveyors can transport many different types of materials, including powdered, granular, small block materials, etc. It can transport in horizontal, inclined and even vertical directions. However, vertical transportation requires higher design and power for the spiral blades. At the same time, in pursuit of conveying efficiency, the larger the pitch of the spiral blades on the auger conveyor, the more materials can be pushed. However, the increase in pitch will also increase the risk of material blockage. Since the raw materials are squeezed by the spiral blades during transportation, the materials are stacked together and easily stick together. The materials that stick together are accumulated during transportation, and the friction with the inner surface of the conveyor gradually increases, which leads to the generation of material blockage. In order to improve the conveying efficiency of the auger conveyor and reduce the frequency of material blockage, the utility model proposes a spiral blade for a conveyor auger.

[0004] In addition, the existing Chinese patent publication number CN212892827U discloses an anti-blocking powder screw conveyor, comprising: a material box, a feeding auger shaft, auger blades and bulk material parts arranged in the material box, the material box comprising a large inner diameter portion and a small inner diameter portion connected through each other; wherein the inner diameter of the large inner diameter portion is larger than the inner diameter of the small inner diameter portion; the feeding auger shaft passes through the large inner diameter portion and the small inner diameter portion; the auger blades are spirally wound around the feeding auger shaft along the axial direction of the feeding auger shaft; the bulk material part is arranged in the large inner diameter portion, and the bulk material part includes at least one tubular bulk material pipe spirally wound around the feeding auger shaft along the axial direction of the feeding auger shaft; and the outer diameter of the tubular bulk material pipe relative to the feeding auger is larger than the outer diameter of the auger blades relative to the feeding auger. However, the following deficiencies still exist in actual use:

[0005] The above patent, when in use, breaks up and assists in pushing the material when it is injected by setting auger blades and bulk parts, breaking up the front end of the material conveying, but the subsequent raw materials will still stick to the middle and rear ends of the conveying during the conveying process, causing blockage.
