Abstract
PURPOSE: To miniaturize structural parts for corresponding to a force acting on both a supporting mechanism and a cylinder by rotating a pipe arrangement change-over device around the axis of a perpendicular pipe of a chage-over pipe arrangement as a rotating axis and making it possible to install the supporting mechanism at the center part of the device in the proximity of the cylinder.
CONSTITUTION: The cylinder 1 is filled with concrete by a piston 2 from a suction port of the cylinder 1 in the suction stroke through the first connecting port 3a opened within a hopper 7 of a pipe arrangement change-over device 3 rotating around the axis of the perpendicular pipe of the change-over pipe arrangement 4 as a rotating axis. Then, the rotating shaft 15 of the change-over pipe arrangement 4 is rotated by a hydraulic cylinder 10 through a swinging arm 16, the one-side opening of the change-over pipe arrangement 4 is communicated with the cylinder 1 filled with concrete through the second connecting hole 3a of the pipe arrangement change-over device 3. In this manner, the pipe arrangement device 3 rotates around the axis of the perpendicular pipe of the change-over pipe arrangement 4 as a rotating axis, and the supporting mechanism of the center part of the device 3 is installed in the proximity of the cylinder 1. Therefore, the structural parts for corresponding to act on both the supporting mechanism and the cylinder can be miniaturized.
