Impact type geological exploration drilling machine

The invention discloses an impact type geological exploration drilling machine, which adopts the principle that a piston cylinder is used for driving a large-lead non-self-locking screw mechanism to move up and down so as to realize positive and negative rotation of a screw, and the working purpose is achieved by impact motion generated by releasing energy stored by a flywheel in the working process. The whole machine can generate stronger working capacity under the conditions of lower power and smaller structural space, and can be suitable for carrying out drilling operation on a geological structure which is difficult to drill. 一种冲击式地质勘探钻机，它所采用的原理是利用活塞缸驱动大导程无自锁螺杆机构上下运动实现螺杆的正反转运动、利用飞轮储存能量在工作过程中释放产生的冲击运动达到工作目的，本发明能够使整个机构在较小功率与较小结构空间的情况下产生较强的工作能力，能够适应对难以钻削的地质结构开展钻探作业。
