込用ノズル装置。[Scope of Claim for Utility Model Registration] 1. A container 1 of a concrete mixer that is attached to the container 1 facing slightly downward from the horizontal in order to inject gas into the concrete in the container from the gas blowing hole 6 drilled in the side of the container. A gas blowing nozzle pipe 7 and a valve rod 8 attached to the inside of the nozzle pipe so as to be movable back and forth for opening and closing the blow hole, the valve rod being moved forward and in the closed position. When,
A gas blowing nozzle device for a concrete mixer, in which a tip end surface 8a of the valve stem is formed obliquely with respect to the axis so as to coincide with the inner surface of the container. 2. In order to inject gas into the concrete in the container from the gas injection hole 6 drilled in the side of the container 1 of the concrete mixer, a gas injection nozzle pipe 7 is attached to the container slightly downward from the horizontal direction. , which is equipped with a valve stem 8 that is attached to the inside of the nozzle pipe so as to be able to move back and forth in order to open and close the blowing hole, and an actuator 10 that moves the valve stem back and forth, during gas blowing. A timer 17 is installed in the drive circuit of the actuator so that the actuator periodically comes to the closed position.
Gas blowing nozzle device for concrete mixer with built-in.
