Then, after the initial inclination of the tank 110 is set, when the tank 110 is inclined beyond the allowable range (set value) of the inclination sensor 190 , the operation member 153 is controlled by the control unit 195 . The operation is controlled and the inclination of a specific hinge tube 151 or all of the hinge tubes 151 is adjusted.

As a result, the injection nozzle 140 can intensively inject the liquid to the injection (control) object as the injection direction can be easily set, so that the injection amount of the liquid is reduced, and the control efficiency is improved.

Meanwhile, the driving source 132 according to the present invention may be variously applied to a battery, a motor, or an engine. In addition, the pumping member 130 and the operation member 153 may be electrically connected to the same driving source 132 , or may be electrically connected to individual driving sources 132 , respectively. Accordingly, one or more driving sources 132 are provided.
