トポンプの吸入吐出切換装置。 A box for switching suction and discharge is installed between the two suction ports opened at the bottom of the concrete hopper and the two concrete cylinders of the concrete pump, and two suction pipes and one pipe are installed inside the box. A slider assembled with discharge pipes is housed in a slidable manner so that any one suction pipe and one discharge pipe communicate with the two concrete cylinders, and the above-mentioned 2.
The other end of the suction pipe is slidably engaged with the outer surface of the concrete hopper so that it slides into communication with the two suction ports, and further communicates with the one discharge pipe to discharge concrete. A suction/discharge switch for a concrete pump, characterized in that a swinging pipe is swingably provided outside the concrete hopper, and one end of the swinging pipe is slidably along the rear surface of the box. Device.
