According to the present invention, the storage container includes a support net for seating a pump at a lower end therein, and an outlet at the lower end to allow a bottom surface to be inclined to one side to collect content at a lower side thereof. A control valve is installed in the outlet to adjust the discharge amount, an underwater pump is selectively stored in the support net of the storage tank for use, and an opening and closing valve separately from the control valve is provided in the outlet. Also, the separate control valve for controlling liquid is mounted on the main body to connect an injection pump and an injection nozzle by coupling, the spray pipe is mounted on an arm by a clip to allow the spray pipe to be horizontally rotated by driving of a forward and backward motor, and an exhaust gas guide communication is formed to be adjacent to an exhaust port of an engine. In addition, the control valve includes a housing and a valve gate, and a winding wheel is formed to be integrated with the valve gate, separate wires are wound around the winding wheel in opposite directions to install an end of the wires in an operation direction facing the control lever, and each of the wires are selectively pulled in accordance with an operation direction of the control level to rotate the winding wheel so as to open and close the valve gate formed to be integrated with the winding wheel.본 발명은 액체로 된 약재는 물론 분말로 된 약재와 비료, 퇴비 유박을 넓은 면적에 대
