装置である。SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and loads the transport material from the center and rotates the screw in the forward or reverse direction to move the transport material left or right. The present invention was applied to a device for preventing clogging in a discharge side casing of a forward and reverse rotary screw conveyor for separating and conveying, and employed the following technical means. That is, a left-handed auxiliary screw blade and a right-handed auxiliary screw blade each having a twist angle smaller than the twist angle of the screw blade are attached to the screw shaft in the casing ahead of the outlet of the screw conveyor. This is a device for preventing clogging in the discharge side casing of the forward / reverse rotating screw conveyor.

る。With the present invention constructed as described above, even if the screw blade is rotated in both the forward and reverse directions, the auxiliary screw blade which conveys the material in a direction opposite to the direction of the material conveyed by the screw vane causes the discharge side. The transport material can be discharged from the discharge port without clogging in the casing.

FIG. 1 is a perspective view of an auxiliary screw blade and a conveying screw blade. FIG. 2A is a side view explanatory diagram, and FIG. 2B is a cross-sectional view taken along the line AA of FIG. 2A. The features of this application are
Auxiliary screw blades 5 for transporting the material in the same direction as the screw blades 4 for transport to the screw shaft 7 in the casing 8 ahead of the discharge port of the screw conveyor, and an auxiliary for transporting the material in the opposite direction to the screw blades 4 for transport. That is, the screw blade 6 is provided.
