Advantages
Saintyol DAWIN Robot shotcrete Spraying Machine advantages are as below: Variable Main Hydraulic Pump
Spraying capacity continuously adjustable (stepless speed change ) Variable Plunger Accelerator Pump
Accelerator feeding quantity continuously adjustable, Stepless adjust in range 0-9% . Placing boom control valve
Placing boom controlling valve is proportional valve, mild and flexible. Brand Engine
Torque, Powerful, Long life, Easier in maintenance. , Separated 2 parts, The trailer shotcrete Pump could be use separately.
The mobile robot spraying machine could work as a trailer, the behind shortcrete pump could spraying jobs separately. Hydraulic fittings.
ALFAGOMMA Fittings Italy or Gates fittings U.S. Cordless remote control
Imported cordless remote control, reliable, stable signal, easier operation. Accelerator feeding and control technology
Brand weighing pump, precise in weighing, Atomizing jet and spraying nozzle material mixed to make accelerator to mix with concrete equality. Low rebound rate
Concrete rebound rate in 15-50% when dry spraying. Even less than 10% in rebound rate when wet spraying, cost saving effectively. High effectively wet spraying.
Robot shotcrete spraying machine use high grade placing boom+robot arm, flexible operation, large working range, safety, reliable and effective. Labors saving.
Comparing to manual concrete spraying by workers, Robot Spraying machine could be adjust into full load working condition, around 2-3 times higher working rate than manual and labors saving more than 3 at least.
Auto mobile truck Pumps for Wet-Mix. Shotcreting with 30m3/hr gunite capability
At present, Wet Concrete shotcrete Pump Truck with Cordless remote control Smart Articulated Robotic Placing Booms is the New Design in 2018 for effective Tunnel Jobs.
A. Front and rear leg the span is large, work stability.
1.The front leg adopts horizontal telescopic cylinder + H-type legs, legs span is large, The rear leg adopts eight characters closed type leg, forcing ability is good, more stability, can effectively support the rear hopper pumping concrete cylinder loading impact.
B. Pumping system
1) Pumping hydraulic system adopts 55KW four-pole motor 130ml/r adjustable displacement main pump+ 45ml/r variable pump (Rexroth series)
2) The main valve adopts imported eight proportional valve (BARMAG ) from German,
The electric proportional valve has the fixed-variable switching function.
C.The boom adopts symmetrically arranged structure
The boom is symmetrically arranged with a symmetrical structure. The telescopic arm is connected to the base arm on the same axis. The telescopic arm is directly connected to the base arm through the pin. No connecting arm, no lateral force, no stress concentration, no happen Fatigue cracking, so the boom system is more stable and reliable.
D.Swinging arm
the boom can swing ± 45 °. can increase the flexibility of the jet mechanism to improve the single sprayable area, not only the spray surface is more smooth, beautiful, but also reduce the turntable rotation times, increase the stability of the boom
E.Boom section
Telescopic arm with four BS700 high-strength steel plate welded after welding,
weld joints have a lap bar, The rigidity of the boom increases so that the telescopic arm has a small vibration amplitude under the wet spraying operation, good stability, can improve the quality of sprayed surface
