Abstract

PURPOSE: To reduce a return moment to a hopper by the system such that the repelling force of pressure transport exerted on the hopper by the concrete ejected alternately from a pair of pump cylinders is sustained by the back wall of the hopper via a Y switching conduit.
CONSTITUTION: When expansion-contraction cylinder 15 is operated, switching conduit 7 is oscillated right and left along the axis L-L via arm 14 and oscillation drive shaft 13, and the open ends of branch pipes 11 and 12 are connected alternately to pump cylinders 9 and 10. At this time, when branch pipe on one side is connected to cylinder 9, branch pipe 12 on the other side is brought into contact with back wall 6 via junction ring 16 and is closed. When cylinder 9 on one side is opened to suction-transport chamber 3, this cylinder 9 is in the suction stroke and sucks concrete from hopper 1. During this time, cylinder 10 is in the compression stroke and supply concrete from discharge pipe 8 via branch pipe 12.
