Digging claw of excavator special for digging square stones and control system for digging claw
The invention discloses a digging claw of an excavator special for digging square stones, and relates to the technical field of digging claws of digging claw machines. The digging claw comprises an excavator bucket and an excavator tooth structure. The excavator bucket comprises a U-shaped frame body and two U-shaped plates. Rectangular holes are uniformly formed in the side surface of the U-shaped frame body; the U-shaped plates are connected through the springs to form the excavator bucket; slotted holes are uniformly formed in two opposite end surfaces of the U-shaped frame body; the otherend of the spring is fixed on the edge of one end surface of the U-shaped plate; sliding shafts are uniformly distributed and fixed on the edge of one end surface of the U-shaped plate; the sliding shafts are in clearance fit with the slotted holes. According to the invention, the U-shaped frame body and the two U-shaped plates are connected through the springs, and the sliding shafts and the slotted holes are installed in a sliding mode, so the volume of the excavator bucket is variable; meanwhile, a control panel controls a hydraulic rod to stretch out and draw back so as to control the digging tooth structure to rotate, square stones are prevented from sliding down in the moving process of the digging claw, and the safety in the moving process of the digging claw is guaranteed while thesquare stone digging efficiency is improved.
本发明公开了一种专用于挖取方石的挖掘机挖抓，涉及挖爪机挖抓技术领域。本发明包括挖斗和挖齿结构，挖斗包括U型框体和两U型板；U型框体侧面均布开设矩形孔；U型板通过弹簧连接构成挖斗；U型框体相对两端面均布开设槽孔；弹簧一端固定在槽孔底部，另一端固定在U型板一端面边缘；U型板一端面边缘均布固定滑动轴；滑动轴与槽孔间隙匹配。本发明还提供一种专用于挖取方石的挖掘机挖抓的控制系统。本发明通过U型框体和两U型板通过弹簧连接并通过滑动轴与槽孔滑动安装实现挖斗体积的可变，同时通过控制板控制液压杆伸缩进而控制挖齿结构旋转，避免挖抓移动过程中方石滑落，提高了方石挖取的效率同时保证挖抓移动过程中的安全性。
