The course of work of the invention is：
Folding hydraulic cylinder control sludge barrel body is opened, the three section telescopic arms that rotating hydraulic cylinder actuating sleeve is combined around rotary shaft from
Vertical state is changed into horizontality, and second section telescopic arm, Section of three telescopic arm stretch out and for mud cylinder to be sent to well center,
Mud cylinder closure holds two drilling tools being connected with each other tightly, and two junctions of drilling tool are bored in mud cylinder centre position, upper end
Tool is turned on, and mud sprays and is sealed in sludge barrel body, is recycled in mud ditch through mud veclamation assembly；Treat in sludge barrel body
After mud fully enters mud veclamation assembly, mud cylinder is opened, and second section telescopic arm, Section of three telescopic arm are fully retracted, and is revolved
Turn Driven by Hydraulic Cylinder fit three section telescopic arms together and be changed into vertical state state, folding hydraulic pressure from horizontality around rotary shaft
Cylinder control mud cylinder closure, completes one action process.
The beneficial effects of the invention are as follows：
（1）The present invention is wrapped up link together two drilling tools by slush pump cylinder, when drilling tool is opened, in drilling tool
Mud be sealed in sludge barrel body, be recycled to mud ditch through mud veclamation assembly, effectively prevent in drilling tool remaining mud
Pollution of the injection to environment, the mud noresidue in drilling tool is all recovered, and has saved production cost；
（2）Three section telescopic arm fits together, control it to stretch out contracting by telescopic hydraulic cylinder in the present invention, and mud cylinder is delivered to
Well center, can make telescopic arm realize 90 ° of rotations, compact conformation of the present invention, floor space around rotary shaft by rotating hydraulic cylinder
It is small, the layout of rig floor is not influenceed；
（3）The present invention by rotating hydraulic cylinder, telescopic hydraulic cylinder, folding hydraulic cylinder realized thribble dismantle drilling tool it is single when brill
Remote automation, the all-hydraulic control of residual slip, time saving and energy saving in tool.
