Bidirectional blade type material pushing and crushing multifunctional shafted quasi-spiral body of quasi-spiral conveyor

The utility model relates to a bidirectional blade type material pushing and crushing multifunctional shafted quasi-spiral body of a quasi-spiral conveyer, which is characterized in that an existing single-function shafted spiral body is improved into a multifunctional shafted quasi-spiral body, and the multifunctional shafted quasi-spiral body comprises a spiral rotating shaft and dual-purpose blades; the dual-purpose blades are material pushing and crushing dual-purpose blades replacing special spiral blades, a plurality of blades are welded on the upper portion, the lower portion, the left portion and the right portion of a rotating shaft in a spaced and inclined mode in a spiral mode, the blades arranged on the rotating shaft in a spaced mode form a discontinuous quasi-spiral shape, and the multifunctional shafted quasi-spiral body is integrally formed. The dual-purpose blade rotates along with the spiral rotating shaft, the axial component force of the dual-purpose blade can push a filter cake, and the r
