Description

Multi-section combined type auger

Technical Field

The invention relates to the technical field of conveyors, in particular to a multi-section combined type auger.

Background

The auger is also called a screw conveyor, and is a machine which utilizes a motor to drive blades to rotate spirally and push materials to achieve the purpose of conveying. The screw conveyer can convey materials horizontally, obliquely or vertically and has the advantages of simple structure, small cross section area, good sealing property, convenient operation, easy maintenance, convenient closed transportation and the like. The principle of operation of screw conveyors is that a rotating screw blade pushes material to be conveyed from one place to another. Structurally, a rotating shaft of the screw conveyor is welded with a screw blade, and the shape of the blade is different according to different conveyed materials, and the blade specifically has the forms of a solid surface type, a belt surface type, a blade surface type and the like. The existing auger basically has an integral long rotating shaft, and cannot be made too long in the actual use process. Therefore, when the conveying distance is longer, the length of the auger cannot meet the requirement, and the auger can only be used for conveying in sections, so that the conveying cost is increased, and the working efficiency is influenced. If a longer articulated dragon is used, the bending deformation of the rotating shaft can be caused during the operation, and the breakage of the rotating shaft can be caused in serious cases, so that the whole conveyor equipment can not work normally, and the working progress is influenced. In addition, when transporting it can happen that material gets entangled in the auger or that the screw blade gets stuck, such a long rotating shaft can make maintenance difficult.
