In embodiments of the present invention, it is illustrated in figure 3 the circuit diagram of electrical system.
Rotary knob potentiometer R1 resistor two ends are connected with proportional amplifier A1 pin (0) and pin (10V) respectively, its
In, pin (10V), which provides 10V output voltage, pin (0) earthing pole, therefore proportional amplifier A1 for resistor, to be rotation
Button potentiometer R1 resistor provides 10V voltage.Third gear does not reset rocker switch S1 input connection proportional amplifier A1
Pin (IN), the voltage range of the input voltage signal of pin (IN) is 0-10V.Input is divided into third gear, its act on be by
The function of water mist dust-removing system is divided into third gear, i.e., 0 grade, I grades and II grade.When third gear, which does not reset rocker switch S1, is in 0 grade
Wait, the input that third gear does not reset rocker switch S1 is not connected with rotary knob potentiometer R1, hold proportional amplifier A1 pins (IN)
No-voltage signal is inputted, so that water mist dust-removing system is closed.I grades are in when third gear does not reset rocker switch S1
When, third gear does not reset rocker switch S1 input connection rotary knob potentiometer R1 moveable slider, makes scaling
The input voltage signal at device A1 pins (IN) end changes with rotary knob potentiometer R1 change, i.e., by making rotary knob potentiometer R1
Knob forward direction or rotate backward, the water-carrying capacity size that regulation water mist dust-removing system sprays, so that water mist dust-removing system
The water-carrying capacity size of ejection is in adjustable mode.When third gear, which does not reset rocker switch S1, is in II grade, third gear does not reset
One end that rocker switch S1 input connection rotary knob potentiometer R1 is connected with proportional amplifier A1 pin (10V), makes ratio
The input voltage signal at amplifier A1 pins (IN) end is maximum, now, and the water-carrying capacity that water mist dust-removing system sprays is in maximum norm
Formula.
Proportional amplifier A1 pin (GND) ground connection, pin (24V) connects power supply, for making proportional amplifier A1 just
Often work.
Proportional amplifier A1 is in central role in whole electrical system, and it is mainly by rotary knob potentiometer R1 resistance
Signal is converted into the input voltage signal at proportional amplifier A1 pins (IN) end, then the voltage signal is converted into electric current output.
Proportional amplifier A1 pin (PWM+) and pin (PWM-) connect the two ends of the first valve Y1 coil respectively.Will be scaling
Device A1 is set to the output current linear proportional relation that the input voltage signal at pin (IN) end is held with pin (PWM+), and makes
Output current is adjustable.The parameters that therefore, it can comparative example amplifier A1 are configured, wherein, maximum output current
I-MAX can be set according to the rated current of the first valve Y1 coil, i.e., maximum output current I-MAX is set as into the first valve
Door Y1 rated current.For example, the first valve Y1 rated current is 1A, then maximum output current I-MAX setting value is
1A.Minimum output current I-MIN can be according to being set the need for electrical system, and ordinary circumstance is set to 0, that is, works as pin
(IN) when end input voltage signal is 0, the output current at pin (PWM+) end is also 0.But, when there is other operating mode needs
When, such as when pin (IN) end input voltage signal is 0, the first valve Y1 needs 0.3A electric current, now can be by
Minimum output current I-MIN value is set as 0.3A.Slope t-ramp values can be adjusted to be raised to most by minimum output current I-MIN
In big output current I-MAX time, the rising of the output current at pin (PWM+) end is accelerated or slowed down, and makes the rate of climb
Reach expection.Chatter frequency f is primarily to cancel the magnetic hysteresis effect of the first valve Y1 coil, the general basis of this setting value
The requirement of coil gives.In embodiments of the present invention, model 7000-31261-0000000 proportional amplifier is maximum defeated
Go out electric current I-MAX for 0-2.5A, minimum output current I-MIN is 0-1A, slope t-ramp values are 0.2-10S, and chatter frequency f is
40-400Hz。
With reference to Fig. 3, the operation principle of the electrical system of the embodiment of the present invention is as follows：
For example：It is 800mA by maximum output current I-MAX setting values, minimum output current I-MIN setting values are 0mA, rotation
Button potentiometer R1 resistance is 10K Ω.The electric current of first valve Y1 coil is 0-800mA.
When third gear, which does not reset rocker switch S1, is in 0 grade, the no signal of wire 186 is proportional amplifier A1 pins
(IN) no signal is held, proportional amplifier A1 pins (PWM+) are held without output current, and the first valve Y1 is closed.
When S1 is in I grades, wire 186 and 188 is turned on, the input voltage letter at proportional amplifier A1 pins (IN) end
Number be equal to rotary knob potentiometer R1 1 pin and 2 pin two ends between voltage.And the output electricity at proportional amplifier A1 pins (PWM+) end
Stream is in linear proportional relation with the input voltage signal that proportional amplifier A1 pins (IN) are held.With rotary knob potentiometer R1 knob
Exemplified by when being screwed into centre position, the resistance between rotary knob potentiometer R1 1 pin and 2 pin two ends is 5K Ω.Now ratio is put
The input voltage signal at big device A1 pins (IN) end is that 5V, i.e. input duty cycle are 50%, therefore, proportional amplifier A1 pins
(PWM+) output current at end is 400mA, and the first valve Y1 opening degree is 50%.It can be seen that, proportional amplifier A1 pins
(PWM+) ratio of the output current at end and the first valve Y1 opening degree is identical with input duty cycle.
When S1 is in II grade, wire 186 and 187 is turned on, the input voltage at proportional amplifier A1 pins (IN) end
Signal is 10V, i.e., input duty cycle is 100%, therefore, and the output current at proportional amplifier A1 pins (PWM+) end is 800mA,
First valve Y1 opening degree is 100%.
In summary, the operation principle of the water mist dust-removing system of the embodiment of the present invention is：
When rig is in the perforate stage, according to the rubble situation in the situation and hole of rock layer surface, water mist dust-removing system is opened
System, blows slag function while opening, water is taken position of opening to by powerful air-flow.Water is taken out of due to powerful air-flow from nozzle, reaches
The water of position of opening is into mist-like.Now the rock ash in hole can be combined into relatively large particle with water smoke and be attached to hole
On wall, it so can not only suppress the diffusion of rock ash, additionally it is possible to play a part of retaining wall solid hole.In use, water mist dust-removing system
Flow-rate adjustment can be divided into third gear, the water-carrying capacity of ejection can be in real time adjusted.
In the process it should be noted that particularly significant using the regulation of air quantity when blowing slag function, typically using small wind
Amount, can allow the conjugate of rock ash and water to be blown if using Wind Volume, the effect of retaining wall solid hole not reached thus.
Therefore, can effectively to solve the rock ash that rig runs into perforate big for the water mist dust-removing system of the embodiment of the present invention
It is difficult with retaining wall solid hole, it can preferably adjust the water-carrying capacity of water mist dust-removing system ejection in real time according to the perforate situation at scene,
Prevent in boring procedure, the rubble or disintegrating slag of bore edges are fallen into hole, improve drill hole of drilling machine quality and drilling efficiency, improve
Boring work environment.
More than, it is only the schematic description of the present invention, it will be recognized by those skilled in the art that in the work without departing from the present invention
Make on the basis of principle, a variety of improvement can be made to the present invention, this belongs to protection scope of the present invention.
