The invention discloses a hydraulic grab bucket of a trash remover and a hydraulic control system. A fixed rake and two or more movable rakes hinged with the fixed rake are included, each movable rakeis provided with a hydraulic oil cylinder for driving the movable rake to be opened and closed, the hydraulic control system further comprises an M-shaped electromagnetic reversing valve, an electriccontact pressure meter, a one-way valve, an oil pump, an overflow valve and an oil tank, the hydraulic grab bucket of the trash remover is provided with two or more movable rakes free of rigid connection, opening and closing of each movable rake can be controlled by the independent hydraulic cylinder, the closing amplitude of each movable rake can be adjusted according to the size of actually-grabbed trash, and the condition that due to uneven stress of all parts of the grab bucket, the hydraulic grab bucket can be wholly damaged can be avoided.
本发明公开一种清污机的液压抓斗及液压控制系统,定耙和两个以上分别与定耙铰接的动耙,每个动耙上都设有驱动该动耙开合的液压油缸。液压控制系统,还包括M型电磁换向阀、电接点压力表、单向阀和油泵,以及溢流阀和油箱。本发明的清污机的液压抓斗的设置了两个以上动耙,动耙与动耙之间无刚性连接,而且每个动耙的开合由单独的液压油缸控制,每个动耙闭合的幅度可以根据其实际抓取的垃圾的尺寸来调整,从而避免抓斗各个部分受力不均匀,以至于液压抓斗整体被破坏的情况。
