The present invention relates to a device for removing gravel and impurities in sand capable of collecting impurities such as small gravel and impurities separately from pure sand conveniently and efficiently from the ground of a playground, a riverside, or a sandy beach and treating the surface of the sand evenly. An engine unit is installed on an under frame which includes a caterpillar unit in the lower part and a horizontal support at the rear side, and a driving rotation shaft is driven by the power from the engine unit. A cap is installed onto the driving rotation shaft, and a rotation member is connected to the cam. A vibration screen unit is installed while being connected to the rotation member and the horizontal support. The vibration screen unit moves back and forth to filter out gravel and impurities from sand to the back, and the filtered-out gravel and impurities are collected by a collection unit installed at the rear side.

    본 발명은 무한궤도부를 하부에 구비하고 후방에 수평지지대를 구비한 차대에 설치된 엔진부의 동력을 전달받아 구동되는 구동회전축에 설치된 캠과 연결된 회동부재와, 회동부재 및 수평지지대와 연결되어 설치된 진동스크린부가 전후방으로 진동되도록 하여 모래에 섞인 돌 및 불순물을 후방으로 걸러내어 수평지지대의 후방에 설치된 수집부에 수집되도록 하여 놀이터와 해변가 또는 강가에 형성된 백사장 모래밭의 모래속에 섞인 작은돌 또는 돌 및 작은 쓰레기와 같은 불순물을 편리하고 효율적으로 순수모래와 돌 및 불순물을 구분하여 분리수거하고, 모래표면을 고르게 정리하도록 한 모래에 섞인 돌 및 불순물 제거장치에 관한 것이다.
