The present invention relates to a manufacturing method of a boat ship body for spraying drugs, which molds a drug tank as one body with a lower ship body and an upper ship body to reduce cost price and the overall costs. According to the present invention, the manufacturing method of a boat ship body for spraying drugs comprises: a first step of preparing an upper ship body molding frame and a lower ship body molding frame, respectively; a second step of forming a drug tank entrance on a penetrating hole of the upper ship body molding frame; a third step of manufacturing an upper ship body and a lower ship body in the upper ship body molding frame and the lower ship body molding frame; a fourth step of placing a separately manufactured drug tank body on an internal side surface of the upper ship body, and integrating the drug tank body and the upper ship body as one body to keep the part between the drug tank body and the upper ship body airtight; a fifth step of making the upper ship body and the lower ship body, which are manufactured by using the upper ship body molding frame and the lower ship body molding frame, come into contact with each other and molding the same as one body; a sixth step of separating a spiral inducing member and a blocking plate from the upper ship body molding frame, forming a screw unit on an external side surface of the drug tank entrance, and separating the upper ship body and the lower ship body from the upper ship body molding frame and the lower ship body molding frame; and a seventh step of opening an upper surface of the drug tank entrance.

    본 발명은 하부 선체, 및 상부 선체에 약품통을 일체로 성형하여 제원가를 줄임과 아울러 전체적인 코스트를 절감할 수 있는 약품 살포용 보트 선체 제조방법에 관한 것이다. 본 발명의 약품 살포용 보트 선체 제조방법은 상,하부 선체 성형틀을 각각 준비하는 제1단계와; 상기 상부 선체 성형틀의 관통공에 약품통 입구를 형성하는 제2단계와; 상,하부 선체 성형틀의 내측에 상,하부 선체를 제조하는 제3단계와; 상부 선체의 내측면에 별도 제조된 약제탱크몸체를 배치한 후, 상기 약제탱크몸체와 상부 선체 사이에 기밀을 유지하도록 일체로 형성하는 제4단계와; 상,하부 선체의 성형틀에 의해 제조된 상,하부 선체을 맞대어 서로 일체로 성형하는 제5단계와; 상부 선체 성형틀에서 나선유도부재와 막음판을 분리하며 상기 약품통 입구의 외측면에 나사부가 형성됨과 아울러 상,하부 성형틀에서 상,하부 선체를 분리하는 제6단계와; 상기 약품통 입구의 상부면을 개방하는 제7단계로 이루어진다.
