摘要： PROBLEM TO BE SOLVED: To facilitate a cleaning work of residual concrete when concrete is choked at a force-feeding pipe position or after shooting operation, thus to improve the maintenance.
SOLUTION: A concrete force-feed pipe 7 arranged right below a main frame 9 is straight and an elbow-shaped guide cover 20 for falling guiding to the impeller 2a side of the main pulley 2 is mounted turnably around a supporting point of a pin 21 at the extremity side. An elbow-shaped attachment 23 is detachably attached to the rear part of the concrete force-feed pipe 7 and the upper part of a concrete supply pipe 8 to connect both pipes 7, 8. When the attachment 23 is demounted, the removing work of concrete adhered to the inside of the attachment 23 at a separate place can be carried out. By removing the front cover 1a of a shooting head 1 and also removing a fixing sleeve 6 and the front cover of the main pulley 2, and further largely opening the front opening of the force-feed pipe 7 by tilting rearward the guide cover 20 with the pin as a support 21, concrete adhered to the inside of the force-feed pipe 7 is easily removed by jetting out water through a hose 24 or the like.
