Abstract

다양한 구질의 투구와 함께 장소에 관계없이 사용하는 것이 가능하도록, 상하방향으로 형성되는 제1 지지대 및 상기 제1 지지대로부터 수평방향으로 연장 형성되는 제2 지지대를 구비하는 피칭프레임과 상기 제2 지지대에 탑재되는 엔진이 구비되며 일측단이 상기 엔진에 연결되고, 타측단이 상기 제1 지지대를 관통하여 상기 제1 지지대의 외측에 노출되어 상기 엔진의 구동력에 의하여 회전하는 회전축과 상기 회전축의 타측단에 연결되어 회전하는 피칭롤러가 구비될 뿐만 아니라 상기 피칭롤러의 상측 외주면에 위치한 연습구의 상측부를 접촉 지지하는 발사 보조판을 상기 제1 지지대에 연결시키는 보조판 지지대를 포함하는 엔진 구동 피칭머신을 제공한다.
