Earth；First reversal valve 17 is in the right side when opening, and the first reversal valve 17 controls bracing frame hydraulic cylinder 9 and regains, and bracing frame hydraulic cylinder 9 is controlled
Bracing frame 10 processed sets back；First reversal valve 17 is in when completely closing, and bracing frame hydraulic cylinder 9 and bracing frame 10 are static not
Dynamic.
Second reversal valve 18 has that three kinds of states, respectively a left side are opened, the right side is opened and completely closed, at the second reversal valve 18
When a left side is opened, the second reversal valve 18 controls sampling hydraulic cylinder 4 and ejects, and sampling hydraulic cylinder 4 controls soil sampler 7 and is pressed into soil；The
Two reversal valves 18 are in the right side when opening, and the second reversal valve 18 controls sampling hydraulic cylinder 4 and regains, and sampling hydraulic cylinder 4 controls soil sampler 7
Set back；Second reversal valve 18 is in when completely closing, sampling hydraulic cylinder 4 and soil sampler 7 transfixion.
3rd reversal valve 19 has three kinds of states, and a left side is opened respectively, the right side is opened and completely closed, and the 3rd reversal valve 19 is in
When a left side is opened, the 3rd reversal valve 19 controls soil sample and loosens hydraulic cylinder 6 and be flipped up, soil sample loosen hydraulic cylinder 6 control soil sampler 7 to
Upper upset；3rd reversal valve 19 is in the right side when opening, and the 3rd reversal valve 19 controls soil sample and loosens hydraulic cylinder 6 and downwardly turn over, soil sample
Loosening hydraulic cylinder 6 controls soil sampler 7 and sets back；3rd reversal valve 19 is in when completely closing, and soil sample loosens hydraulic cylinder 6 and takes
Earthenware 7 transfixion.
When being sampled operation, first operator enter the operating instructions at wireless operation device 13, wireless operation device
13 pairs of wireless signal receivers 12 export control signal, wireless signal receiver 12 upon receiving the control signal, according to thing
The operational order first inputted can control the startup of mechanical driving device 11, and mechanical driving device 11 drives steel wire rope 8 to move downward,
Steel wire rope 8 drives sampler to enter down-hole, then starts oil pump 2, and oil pump 2 by the oil output in fuel tank 1 outwards pressurizes, to respectively
Oil in parts energy supply, first fuel tank 1 carries out the first reversal valve 17 through flow speed control valve 15, and the first reversal valve 17 is in the control of electromagnetic valve
Lower being first in left opening state, when the first reversal valve 17 is in left opening state, the first reversal valve 17 controls bracing frame hydraulic pressure

Device is reported to the police, and after staff receives instruction, carries out further work；Then electromagnetic valve controls the second reversal valve 18 and enters left open-minded
State, the second reversal valve 18 controls sampling hydraulic cylinder 4 and works, and sampling hydraulic cylinder 4 controls to enter in soil sampler 7 stretches out and inserts soil
Row sampling, subsequent section oil enters again the overflow valve 16 at fuel tank 1, overflow valve 16 overflow, alarm equipment alarm, and staff receives
After instruction, enter further work；Extracting sampling soil, electromagnetic valve controls the 3rd reversal valve 19 and is in left opening state, and the 3rd
Reversal valve 19 controls soil sample and loosens hydraulic cylinder 6 and work, and meanwhile, controls soil sampler 7 and is flipped up, it is achieved fetch earth, and subsequently, oil flows into
Overflow valve 16, overflow valve 16 overflow again, alarm equipment alarm；More than for sampling operation.
After sampling completes, staff receives last alarm signal, therefore, it is desirable to take the soil sample taken out
Go out operation in well.First electromagnetic valve controls the first reversal valve 17 and is in right opening state, and the first reversal valve 17 controls bracing frame liquid
Cylinder pressure 9 resets, and support means no longer plays a supportive role, steel wire rope 8 stress again, and controls the second commutation of soil sampler 7 translation
Valve 18, starts to pull soil sampler 7 operation, and reverse with above-mentioned operation, last mechanical driving device 11 pulls steel wire rope 8 and upwards transports
Dynamic, take out sampler, complete whole sampling operation.
Wherein mechanical driving device 11 is driven by power, it is possible to the height that display is gone into the well and promoted, and wants to meet construction
Asking, the diameter of steel wire rope 8 typically uses the steel wire rope 8 of diameter 8-10mm, and the specifications design of the soil sampler 7 of the present invention is
100x100x200mm.Wherein mechanical driving device 11 controls sampler and goes into the well and the speed that promotes is less than 0.5m/s, it is ensured that
The integrity of sampling, runs with this speed, it is provided that power smoothly.
Package unit automaticity is high, solves efficiency and the safety problem needing artificial lower well operations, improves
Working performance, it is ensured that the accuracy of testing result.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and
Modification, these improve and modification also should be regarded as protection scope of the present invention.
