Spiral type leaf throwing roller for wind separating warehouse

Abstract

The invention relates to a spiral type leaf throwing roller for a wind separating warehouse. The spiral type leaf throwing roller comprises a plurality of blades, a roller cylinder and a shaft; the multiple blades are arranged on the outer circumferential surface of the roller cylinder, and the shaft is arranged at the position of the central axis of the roller cylinder in a penetrating mode; themultiple blades are arranged in the direction of spiral lines of the roller cylinder in sequence, the spiral lines, treating the midpoint of the roller cylinder as a boundary, rotate leftward from oneend of the roller cylinder and rotate right ward in the opposite direction from the other end of the roller cylinder, and the spiral lines intersect to one point at the midpoint of the roller cylinder; and the multiple blades rotate leftward along the spiral lines at the end of the roller cylinder, and rotate rightward along the spiral lines at the other end of the roller cylinder. According to the spiral type leaf throwing roller for the wind separating warehouse, the leaf throwing roller is of a hollow structure and has low weight, and the load of a driving motor is reduced; and in addition, the positions of thrown materials can be more uniform, the wind separating effect is improved, and the leaf containing rate in stalks is reduced.

Description

technical field [0001] The invention relates to a leaf throwing roller, in particular to a spiral leaf throwing roller for an air separation bin. Background technique [0002] In the leaf threshing and redrying production line, the tobacco leaves, tobacco stems and other materials torn by the leaf thresher are sent to the air separation warehouse by the rectangular wind conveying pipe for separation of stems and leaves. The leaf-throwing roller in the air distribution bin is placed horizontally, and the material falls on the leaf-throwing roller, and the material is thrown out through the rotation of the leaf-throwing roller, so that the tobacco leaves and tobacco stems are evenly emptied and distributed in the air distribution bin, so as to eliminate the mixed ones. Tobacco leaves and stems are effectively selected by winnowing. [0003] Due to the turbulence of the airflow, unstable wind speed, friction between the material and the pipe wall, the bend of the air duct, and...

AI Technical Summary

Problems solved by technology

[0007] The above two situations lead to the fact that the material cannot float in the air separation bin, and the separation effect of the stem and the leaf is poor, and finally the leaf content in the stem is high, resulting in waste
