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 set according to the needs of electrical system, and ordinary circumstance is arranged 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, for example when pin (IN) end input voltage signal is 0, the first valve Y1 needs 0.3A electric current, can now incite somebody to action
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 expected.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 the utility model embodiment, model 7000-31261-0000000 proportional amplifier is most
Big output current I-MAX is 0-2.5A, and minimum output current I-MIN is 0-1A, and slope t-ramp values are 0.2-10S, and chatter is frequently
Rate f is 40-400Hz.
With reference to Fig. 3, the operation principle of the electrical system of the utility model embodiment is as follows：
Such as：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+) end is closed without output current, the first valve Y1.
When S1 is in I shelves, wire 186 and 188 turns on, the input voltage letter at proportional amplifier A1 pins (IN) end
Number equal to rotary knob potentiometer R1 1 pin and 2 pin both ends between voltage.And the output electricity at proportional amplifier A1 pins (PWM+) end
Stream and the input voltage signal at proportional amplifier A1 pins (IN) end are in linear proportional relation.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 both ends is 5K Ω.Now ratio is put
The input voltage signal at big device A1 pins (IN) end is 5V, i.e., input duty cycle is 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 turns on, the input voltage at proportional amplifier A1 pins (IN) end
Signal is 10V, i.e., input duty cycle is 100%, and therefore, 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 utility model embodiment 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, while open and blow slag function, water is taken position of opening to by powerful air-flow.Water reaches because powerful air-flow is taken out of from nozzle
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 adjusted in real time.
It is 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, the conjugate of rock ash and water can be allowed to be blown if using Wind Volume, do not reach the effect of retaining wall solid hole thus.
Therefore, the water mist dust-removing system of the utility model embodiment can effectively solve the rock that rig runs into perforate
Grey big and retaining wall solid hole is difficult, can preferably adjust the current of water mist dust-removing system ejection in real time according to the perforate situation at scene
Amount, 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, schematic description only of the present utility model, it will be recognized by those skilled in the art that without departing from this practicality
On the basis of new operation principle, a variety of improvement can be made to the utility model, this belongs to protection of the present utility model
