Grab bucket hydraulic system capable of grabbing soil through vibration
The invention discloses a grab bucket hydraulic system capable of grabbing soil in a vibrating manner, which comprises a first pipeline and a second pipeline which are respectively and correspondingly connected with a pressure oil source and an oil tank in a switchable manner; a piston rod of the main pushing oil cylinder is used for being connected with the grab bucket so as to drive the grab bucket to be opened or closed, a rodless cavity of the main pushing oil cylinder is connected with the first pipeline, and a rod cavity of the main pushing oil cylinder is connected with the second pipeline; a first switching valve is connected between an oil inlet of the cycloid motor and the first pipeline, a second switching valve is connected between an oil outlet of the cycloid motor and the second pipeline, the first switching valve is used for controlling connection and disconnection between the cycloid motor and the first pipeline, and the second switching valve is used for controlling connection and disconnection between the cycloid motor and the second pipeline; the cycloid motor is connected with an eccentric block, the eccentric block is connected with the grab bucket, and when the cycloid motor drives the eccentric block to rotate, the grab bucket vibrates in a reciprocating mode in the preset direction. And vibration and impact are superposed while the grab bucket is closed, so that the grabbing force of the grab bucket is improved, and the grab bucket adapts to a harder rock-soil layer.
本发明公开了一种可振动抓土的抓斗液压系统，包括：第一管路和第二管路，两者可切换地分别与压力油源和油箱对应连接；主推油缸，其活塞杆用于与抓斗相连，以驱动抓斗开斗或关斗，主推油缸的无杆腔与第一管路相连，主推油缸的有杆腔与第二管路相连；摆线马达，其进油口与第一管路之间连接有第一切换阀，摆线马达的出油口与第二管路之间连接有第二切换阀，第一切换阀用于控制摆线马达与所述第一管路之间的通断，第二切换阀用于控制摆线马达与第二管路之间的通断；摆线马达连接有偏心块，偏心块与抓斗相连，以当摆线马达带动偏心块旋转时，使抓斗沿预设方向往复振动。在关闭抓斗的同时叠加振动和冲击，提高抓斗的抓取力，使抓斗适应较硬岩土层。
