The present invention relates to a device for adjusting the angle of a moisturizing blade of earth-moving equipment. In existing earth-moving equipment, the angle of a moisturizing blade installed in the front end of an arm cannot be adjusted, so that a ridge cannot be produced in various shapes and sizes according to the kind of crop and moisturizing blades of various angles should be separately prepared, which consumes much cost, time, and manpower caused due to replacement. Accordingly, in the present invention, a first installation hole (112) and a hook hinge unit (113) are produced on the top surface rear part and the front end of an arm (110) rotated up and down by means of a hydraulic cylinder based on a hinge unit (111) at the rear end of a main frame connected with a tractor (10) or a rotary (20). A hook unit (200) inserted in and hung on a moisturizing blade horizontal bar (310) supporting the moisturizing blade (300) on a hanging groove (202) opened and closed by means of a coupling and dislodging hanging chain (210) is installed to be rotated at the hook hinge unit (113) of the arm while a second installation hole (203) is prepared at the top thereof. A hydraulic cylinder or a turnbuckle (400) for rotating the hook unit is installed between the first installation hole (112) of the arm (100) and the second installation hole (203) of the hook unit (200) and the hook unit (200) is pushed and pulled so that a wing unit (302) of the moisturizing blade (300) is adjusted in multiple angles. According to the kind of crop, a ridge can be produced in various shapes and sizes.본 발명은 배토기의 보습날 각도 조절장치에 관한 것으로서, 종래의 배토기는 아암 선단에 설치되는 보습날 각도를 조절할 수 없어 작물 종류에 따라 두둑을 다양한 형태 및 크기로 만들기가 어려웠으며, 여러 각도의 보습날을 따로 구비하여야 하므로 비용이 많이 소요되고 교체에 따른 시간 및 인력 소모가 많았다.이에 본 발명은 트랙터(10) 또는 로터리(20)에 연결된 메인프레임(110) 후미의 힌지부(111)를 기점으로 유압실린더(30)에 의해 상하로 회전되는 아암(110)의 상면 후미와 선단에는 제1설치공(112) 및 걸고리힌지부(113)를 형성하고, 괘,해정용 걸이쇠(210)로 개폐되는 걸이홈(202)에 보습날(300)을 지지하는 보습날 횡바(310)가 끼워져 걸리는 걸고리부(200)는 상부에 제2설
