The grab bucket mechanism comprises a suspension arm, a grab bucket, a variable-amplitude winch, a lifting winch and a bucket winch, the variable-amplitude winch is used for controlling the angle of the suspension arm, the grab bucket is installed on the suspension arm, the lifting winch controls the height of the grab bucket through a take-up and pay-off cable of the lifting winch, the bucket winch controls opening and closing of the grab bucket through a take-up and pay-off cable of the bucket winch, and the invention further discloses a hydraulic control system. The grab bucket has the beneficial effects that the grab bucket moves through the suspension arm, the height of the grab bucket is controlled through the lifting winch, opening and closing of the grab bucket are controlled through the bucket winch, oil is supplied to the main pressure regulating valve group, the rotary valve group, the variable amplitude valve group and the rotary mechanism through the multiple hydraulic pump groups, and therefore the oil supply amount of different devices is guaranteed.
本发明公开了一种抓斗船抓斗机构,包括吊臂、抓斗、变幅绞车、提升绞车和挖斗绞车,变幅绞车用于控制吊臂的角度,吊臂上安装有抓斗,提升绞车通过其收放缆控制抓斗的高度,挖斗绞车通过其收放缆控制抓斗的开合,还公开了液压控制系统。本发明的有益效果是:抓斗通过吊臂进行运动,通过提升绞车控制抓斗的高度以及挖斗绞车控制抓斗的开合,通过多个液压泵组给主调压阀组、回转阀组、变幅阀组和回转机构供油,从而保证了不同器件的供油量。
