摘要：本实用新型公开了一种物探钻机动力头卸扣套自动进给装置。主要由卸扣套、滚轮、拨叉杆、支撑架、液缸、手动换向阀顺序连接而组成。使用时，以钻机原液压系统或气路系统作为动力源，操作手动换向阀使液缸的活塞伸缩，促使拨叉杆旋转，通过拨叉杆上的滑轮带动卸扣套在动力头钻杆接头上滑动，完成钻杆拆卸作业。

主权项：1.一种物探钻井的物探钻机动力头卸扣套自动进给装置，其特征在于：支撑架固定在动力头箱体的下端面上，拨叉杆的中部与之相连，其另外两端则分别与液缸活塞杆和滚轮相连，滚轮镶嵌在卸扣套的滑轨上，液缸的另一端固定在支撑架上而构成；卸扣套可在动力头钻杆接头上滑动，由液压手动换向阀关闭或开启供液使液缸的活塞带动活塞杆伸缩，连动卸扣套在中心管上滑动，实现钻杆的卸扣。
