Cylinder 1 6.1, which is retracted, drives conveyor piston 4.4 to bounce back；When pumping the retraction of oil cylinder 1 6.1, the shape when conveying retraction in cylinder body 4.3
Into negative pressure, flushing water reaches conveying cylinder body 4.3 from 2 external threeway of discharging mechanism by discharging cavity volume 1, when pumping oil cylinder 1 is retracted
During one stroke, right side senses electric close to switch 6.3, and electric, pumping is obtained by logic control two-position four-way solenoid directional control valve 7.4
The direction of motion of oil cylinder 1 6.1 is converted therewith, proceeds by back flush pumping work.
When grouting pump back flush pumps：7.1 right position of three-position four-way electromagnetic directional valve obtains electric, two-position four-way solenoid directional control valve
7.4 obtain electric the next work, two-position four-way pilot operated valve device 2 7.3 by the next work of hydraulic control power, and two-position four-way pilot operated valve device 1 7.2 is by hydraulic control
The next work of power：Control P3 mouth of the hydraulic oil by hydraulic control valve group 7, the bottom through two-position four-way pilot operated valve device 2 7.3, two four
Electric change valve 7.4 is the next, reaches the rod chamber of vertical-lifting valve control cylinder 1 3.4, horizontal poppet control cylinder 1
2.4 rodless cavity, the retraction of vertical-lifting valve control cylinder 1 3.4 opens vertical-lifting valve 1 3.6, horizontal poppet control oil
The stretching of cylinder 1 2.4 closes horizontal poppet 1 2.6；Simultaneously pressure oil-source by hydraulic control valve group 7 P2 mouths, through 3-position 4-way
Right position, the bottom of two-position four-way solenoid directional control valve 1 7.2 of solenoid directional control valve 7.1 reach the rodless cavity of pumping oil cylinder 1 6.1,
Pumping oil cylinder 1 6.1 stretches out under the promotion of pressure oil drives conveyor piston 4.4 to stretch out；When pumping the stretching of oil cylinder 1 6.1, clearly
Wash water can only be pumped away by suction cavity volume 1 3.2, carry out the cleaning of grouting pump；When pumping oil cylinder 1 6.1 stretches out one
During a stroke, left side senses electric close to switch 6.3, passes through 7.4 dead electricity of logic control two-position four-way solenoid directional control valve, pumping oil
The direction of motion of cylinder 1 6.1 is converted therewith, approaches beginning back flush suction work, and from this, the progress that moves in circles is clear
It washes, until cleaning is completed.
