Description

Shaft end mechanism of discharge end of screw conveyor Technical Field The utility model relates to the technical field of screw conveyors, in particular to a shaft end mechanism of a discharge end of a screw conveyor. Background Screw conveyors are continuous conveying devices that utilize rotating screw blades to propel material, and are widely used for conveying particulate or powder materials. Screw conveyer mostly uses the motor to drive screw blade through shaft body through shaft coupling or belt and rotates, and inside this in-process material got into the conveyer through the feeder, the screw blade that passes through the rotation in the conveyer was carried, until the material removes to the discharge end and outwards discharges, if the feeding speed of feeder and the delivery rate of conveyer mismatch in this in-process probably lead to piling up a large amount of materials in the conveyer and increasing the load of conveyer, probably lead to the motor that is connected with the conveyer to break down because the load surpasss the bearing range when the load is too big in the conveyer, the circumstances that the shaft body of installation screw blade warp in the conveyer takes place even.
