OPERATION & MAINTENANCE MANUAL SWDE120B-3
10.3 ROTATING MECHANISM
The rotating mechanism consists of hydraulic motor, main shaft units, connectors, slide
plate and central air supply units. Chains of feeding mechanism are fixed on the slide plate
through shaft and spring shock absorb.
Rotating is driven by two units’ hydraulic motor. The output rev ranges 0 ～ 60rpm after
decelerated by gear box.
10.4 FEED MECHANISM
Feed mechanism consists of hydraulic motor, roller group, chain and buffer spring.
One end of the chain is fixed on upside of slide plate by shaft, the other end connects with
the gyrator via a pin roll after winding through the driven sprocket, the velocity of reelpipe
and gyrator is 1 ： 2, ensuring the slewing pipeline smooth. By operating hydraulic motor,
machine would propel or lift. There is buffer function when feeding hydraulic motor.
10.5 ROD DISCHARGER
Rod discharger consists of up rod discharging body, low rod discharging body, up tongs
mouth, low tongs mouth, rod clamping cylinder and rod discharging cylinder etc. Clamp
the up and low rod by rod clamping cylinder, then operate the cylinder to loose the up and
low rod connecting screw to separate the rod. Lastly, discharge the rod machine by
controlling rotating mechanism.
10.6 DRY-TYPE DUST COLLECTION
A dry-type dust collection device consists of dust hood, cyclone, laminar flow, fan and
pipes. Cover the hole by dust hood tightly, blow up the powder and dust by air fan. Then,
pump it into dust collection device. Large dust particles would be removed by cyclone, small
ones would be removed by laminar flow dust collector. As equipped with solenoid impulse
valve, laminar flow dust collector filter core can be cleaned in proper sequence which keeps
the resistance force within a certain value and promises the dust collecting efficiency. During
assembling, disassembling of Kelly bar or traveling of machine, close the fan exit, the dust
on filter core would be blown off easier. Once the resistance force becomes too large,
disassemble the filter core from the laminar flow dust collector and wash it with high
pressure water.
