The present embodiment is preferred forms, in particle punching drilling process, by starting the first hydraulic cylinder and the second hydraulic cylinder, first Driven by Hydraulic Cylinder first piston bar contraction first piston enters and adds note stroke, oscillating motor starts simultaneously, swing reversing tube to the second conveying cylinder place, make reversing tube carry cylinder to be communicated with second rapidly, the particle in mix particles hopper, slurry mixture just add injection first and carry in cylinder, meanwhile, second Driven by Hydraulic Cylinder second piston rod promotes the second piston and enters compression stroke, extrude from mix particles hopper and the particle, the slurry mixture that are stored in the second conveying cylinder, particle, slurry mixture are injected in high pressure line by reversing tube, and finally enter well Inner eycle, when the second piston movement is to extreme position, compression stroke terminates, second Driven by Hydraulic Cylinder second piston rod shrinks the second piston and enters and add note stroke, reversing tube is swung to the first conveying cylinder place by oscillating motor again, and carry cylinder to be communicated with first, first Driven by Hydraulic Cylinder first piston bar promotes first piston and transfers compression stroke to by adding note stroke, by the particle in the first conveying cylinder, slurry mixture injects in high pressure line by reversing tube, and finally enter well Inner eycle, achieve the alternate run of the first conveying cylinder and the second conveying cylinder since then, particle is enable to be injected continuously in well, as a complete technical scheme, first conveying cylinder, the second conveying cylinder pass through the cooperation of the first hydraulic cylinder and the second hydraulic cylinder and oscillating motor, can realize adding alternately carrying out in order of note and compression stroke, particle in first conveying cylinder, the second conveying cylinder, slurry mixture can replace continuous print and inject in well, ensure that the continuity that in well, particle injects, avoid particle deposition blocking in the first conveying cylinder and the second conveying cylinder simultaneously, effectively improve the operating efficiency of particle punching drilling, in whole device, only the first conveying cylinder, the second conveying cylinder, reversing tube are high pressure conditions, greatly reduce higher-pressure region, improve safety, mix particles hopper injects tank compared with the high pressure particle of prior art, and weight and volume all greatly reduces, and installing space takies few, and it is quite convenient to transport.Spiral mixing rod is provided with stirring vane, stirring vane and spiral mixing rod are slidably connected, stirring dynamics can be increased by arranging stirring vane, shorten mixing time, particle and mud are mixed rapidly, and stirring vane and spiral mixing rod are slidably connected, and can regulate the height of stirring vane in mix particles hopper as required flexibly, what mix to enable particle and mud is more even, prevents particle from high pressure line, depositing blocking further.The cross section of reversing tube, in " S " type, adopts specific " S " type reversing tube, makes commutation process more flexible, no matter reversing tube is carry cylinder to be connected with first, or carry cylinder to be connected with second, all can be communicated with fast, to ensure the continuity that particle injects.
The utility model is not limited to above-described embodiment, as also programmable logic controller (PLC) PLC can be increased, send pulse signal control swinging of reversing tube by programmable logic controller (PLC) PLC can be increased, thus realize the continuous injection of Dual Implantations pump automation, improve particle drilling efficiency.
