CONVEYANCE METHOD AND DEVICE FOR OBJECT TO BE CONVEYED

摘要

PROBLEM TO BE SOLVED: To provide a conveyance technique capable of efficiently conveying a wide variety of conveyance objects, without being affected by viscosity. SOLUTION: A screw auger 4 is pivotally housed inside an auger casing 1, having an intake 2 and an exhaust 3 formed on both ends. A negative pressure generating source 10 is connected to the exhaust part 3 which communicates with a helical space inside the casing 1. Both force of an extrusion force due to frictional force between vanes 6 of the screw auger 4 and a negative pressure suction causes force to act over the entire length of the helical space inside the auger casing 1 acts on a object to be conveyed and conveys it.
