If a worker is needed, another person is required to supervise the concrete pouring process. This type of tank tank requires personnel to be placed in the area where the concrete material is used. Railers are not suitable for use in mine shafts, because bulk concrete This is because a considerable height space is required to discharge the material. Furthermore, the trailer The tractor used to tow the vehicle cannot be released due to insufficient space. stomach.

Hidetan J Old 1 Show It is an object of the present invention that concrete spraying and casting is more effective than conventional dispensing equipment for pouring and pouring. The feature of the device according to the present invention is that it provides a novel dispensing device with high efficiency. The main principles of the invention as set forth in the claims appended hereto are: By configuring vehicles so that there is no need to bring concrete material from the ground. Ru. Second, the pump on the pump vehicle should be located after the cab, and the pump supply funnel should be , a device is installed to prevent overfilling, thereby requiring only one person on the work site. In cases where it is sufficient to deploy personnel, - one person alone can install the pump, jib, and To be able to monitor cleat use. Overfilling the supply funnel , the supply funnel is hermetically connected to the tank discharge opening via a rotatable coupling. It is most advantageous to prevent this by Alerts you when overfilling occurs Although it is in principle possible to use various types of sensors to There are doubts about reliability. Furthermore, interrupting the rotation of the tank will cause a loss of power to the tank. Filling with cleat material is prevented.

From the point of view of the invention, the work carried out by pumping the concrete material is Whether the business is spraying concrete or casting concrete, Actually, the concrete material to be sprayed is ordinary bulk concrete. It is a reed material and is diffused in a nozzle by compressed air.
