Specifically, staff also needs to input depth critical value to controller 11.Controller is according to actual grade and depth
Spend the pressure of critical value control cyclone nozzle injection fluid.For example, when actual grade is more than depth critical value, cyclone nozzle is not reduced
Spray the pressure of fluid；When actual grade is less than depth critical value, the pressure of nozzle injection fluid is reduced.
Preferably, the first depth critical value and the second depth critical value can also be inputted to controller 11.Wherein, first is deep
It spends critical value and is more than the second depth critical value.The pressure of slush pump is reduced when actual grade is less than the first depth critical value；
Actual grade reduces the pressure of slush pump, water pump and air compressor machine simultaneously when being less than the second depth critical value.
Here it should be noted that described at this time is to be reduced rather than directly closing.It needs to control slush pump, water pump
Low-pressure state is maintained with air compressor machine, ensures that pipeline does not block.
Preferably, the controller of the present embodiment controls the promotion speed of power head according to actual grade.For example, when practical deep
When degree is less than depth critical value, the promotion speed of power head is reduced.
In order to play the role of warning to being in the personnel near ground construction place before ground is proposed in cyclone nozzle
So as to prevent that personnel are damaged, the control system of the present embodiment further includes warning device.Controller is according to actual grade control
Warning device processed sends out alarm signal.
Specifically in the present embodiment, warning device includes alarm lamp 16 and/or buzzer 17.
The specific work process of the jet drill rig of the present embodiment is described in detail below.
There is the drilling machine of the present embodiment drilling state and churning to promote two states.Wherein, churning promotes state and includes connecting
Continuous churning state and interval churning state.Staff selects work shape by the state switching part 21 on display 18 first
State.
In the state of drilling：It is maximum opening that controller, which controls the first control valve 3 and the second control valve 4, does not play decompression
Effect, at this point, the promotion speed and rotating speed of power head are set respectively by the first pilot handle 1 and the second pilot handle 2.
When continuous churning promotes state：First pilot handle 1 and the second pilot handle 2 are that maximum is opened by staff
It spends and locks, the promotion rotating speed of power head and rotate forward rotating speed at this time and control (the by the first control valve 3 and the second control valve 4 respectively
The size of current of one control valve 3 is determined that second controls by the numerical value that the promotion speed setting value input unit 19 on display 18 inputs
The size of current of valve 4 processed rotates forward the numerical value that inputs of rotating speed setting input unit 20 by the power head on display 18 and determines, current value
Size according to the power head of input rotate forward rotating speed and promoted speed be calculated automatically).
When interval churning promotes state：First pilot handle 1 and the second pilot handle 2 are maximum opening and lock,
Power head promotes speed at this time, rotating forward rotating speed is controlled respectively by the first control valve 3 and the second control valve 4.And at the same time the first control
The promotion time and promote time out execution power on/off that valve 3 processed is inputted according to display.
In the present embodiment, four depth critical values of storage in controller.Four depth critical values are respectively 0.3 meter,
0.5 meter, 1 meter and 1.5 meters.
The churning control system of the present embodiment performs different actions when cyclone nozzle is in different depth intervals.Specifically
It is as follows：
The actual grade H of cyclone nozzle is sent in controller 11 by depth detection apparatus.
When 1<During H≤1.5 meter, alarm lamp 16 intermittently flickers, and buzzer 17 continuously rings three sound, this alarms for the Ith stage.
When cyclone nozzle is promoted to 0.5<During H≤1 meter, alarm lamp 16 continuously flickers, and 17 continuous interval ring of buzzer, this is
IIth stage alarmed.
When promotion to 0.3<During H≤0.5 meter, 16 high speed scintillation of alarm lamp, 17 continuous ring of buzzer, while slush pump drives
The dynamic automatic reduction of speed of motor is to depressurize, and churning promotes speed and halves, this alarms for the IIIth stage.
16 high speed scintillation of H≤0.3 meter Times warning lamp, 17 continuous ring of buzzer, slush pump driving motor, water are arrived when being promoted
It pumps driving motor, air compressor driving motor to operate with smaller speed, maintains low-pressure state, ensure that pipeline does not block, this is the
IV stage alarmed.
The control system of the jet drill rig of the present embodiment in the cyclone nozzle distance nearer apart from ground according to it is different away from
Different alarm signals is sent out from section preferably to form reminding effect to staff.
Alarm can be released by reset button on display, and stage alarm release or this churning process may be selected
Alarm release：
Certainly, releasing control can also be carried out to alarm signal in above each stage：
Alarm lamp 16 and buzzer 17 are resetted and are stopped after the I, the II stage alarm release.
After IIIth stage alarm release, the still high speed scintillation of alarm lamp 16, the reset of buzzer 17 is stopped.Mud pump motor
Rotating speed does not restore, and churning promotes speed and restores.
After IVth stage alarm release, alarm lamp 16, buzzer 17 are resetted and are stopped, slush pump driving motor,
Water pump driving motor, air compressor driving motor are still operated with smaller speed, maintain low-pressure state, ensure that pipeline does not block.
After the alarm release of entire churning process, alarm lamp 16 and buzzer 17 are resetted and are stopped.Mud at this time
It is corresponding by the stage is presently in pump driving motor, water pump driving motor, air compressor driving motor rotating speed and churning promotion speed
Parameter carries out after stage alarm release, and slush pump driving motor, water pump driving motor, air compressor driving motor rotating speed can be manual
It adjusts, but can only reduce.
In summary, the control system of the jet drill rig of the present embodiment can realize that churning is in jet drill rig promotes shape
The rotating speed of power head and promotion speed carry out automatically controlling to realize precision control during state.And the realization automatically controlled may be used also
To reduce the working efficiency of staff.In addition, actual grade of the control system of the jet drill rig of the present embodiment in cyclone nozzle
Apart from ground it is nearer when, the pressure of fluid pump can also be reduced and reduce the promotion speed of cyclone nozzle so as to prevent high pressure spray
Fluid damages staff.And when the actual grade of cyclone nozzle is nearer apart from ground, alarm lamp can also be controlled
And/or buzzer sends out alarm signal, plays the role of reminding staff, fluid is further prevented to cause to hinder to staff
Evil.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
