The electric hydraulic multi-petal grab bucket comprises a grab bucket base, a hydraulic cabin, a main shaft rod, a control valve set and a hydraulic pump set used for controlling the grab bucket to work, a plurality of grab bucket petals and a driving rod are rotationally installed on the surface of the grab bucket base, the other end of the driving rod is movably connected with the surfaces of the grab bucket petals, and a plurality of plunger cavities are formed in the inner side of the grab bucket base; the control valve sets are arranged on the inner sides of the plunger cavities one by one, communicating pipes communicating with the plunger cavities are arranged on the surface of the driving rod, and a pressure release valve is arranged on the surface of the driving rod. According to the grab bucket, the novel rotary control valve body structure is arranged, the swash plate base is driven by the driving motor to rotate, then the multiple control valve sets are controlled to be opened and closed one by one, and each grab bucket petal can independently move according to the shape, size and resistance of materials by means of sequential control and progressive movement of the grab bucket petals; therefore, the operation flexibility is improved.

    本发明公开了一种电动液压多瓣抓斗,包括:抓斗座、液压舱、主轴杆和控制阀组以及用于控制抓斗工作的液压泵组,抓斗座的表面转动安装有若干抓斗瓣和驱动杆,驱动杆的另一端与抓斗瓣的表面活动连接,抓斗座的内侧设有若干柱塞腔,且控制阀组逐一布置于各个柱塞腔的内侧,驱动杆的表面设有与柱塞腔连通的联通管,且驱动杆的表面设有泄压阀。本发明中,通过设置新型旋转控制阀体结构,在驱动电机驱动下使斜盘座旋转运动进而对多个控制阀组的逐一开合控制,利用对各个抓斗瓣的依次控制和渐进运动,每个抓斗瓣都可以根据物料的形状、尺寸和阻力进行独立运动,从而提高了操作的灵活性。
