XZ320 Horizontal Directional Drill Usage Manual
fixed by anchor device. The probe shall be installed into the drill bit to
connect drill bit body, auger stem and power head for drilling. Mud pump
also shall pump mud during synchronous drilling for soil cutting and heat
dissipation of protective wall and drill bit during drilling or back towing.
Position of drill bit shall be measured by receiving signals issued by probe
in the wireless probe through earth's surface receiver. Power head shall
stop rotation and adjust inclined drill bit plate toward required direction if
necessary. Ground receiver will monitor feeding direction when pushing
power head without rotation. Drilling shall be continued after defining
accurate direction. Direction can be adjusted for many times during drilling
until ending.
Pipe layout: Different re-expanding hole drill bits shall be used after drilling
according to pipe diameter and category for once or multiple back drilling to
reach required aperture. Power divider can be connected to set pipe during
the final back drilling and towing until all pipes are positioned. Mud shall be
supplied during the entire process.

2. Main structure

XZ320 horizontal directional drill is an integral drilling device. It mainly
consists of

chassis,

power head, drilling rig, engine system,
semi-automatic access assembly of auger stem, jaw vice, anchor device,
drilling tool, hydraulic system, electric system and mud system, etc.
2.1 Chassis
Chassis mainly consists of automatic chassis, left and right driving devices.
Hydraulic leg is supplied in the rear of automatic chassis.
Driving device consists of crawler tension device, rubber crawler, drive
wheel, guide wheel, supporting wheel and driving speed reducer, etc.
