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. 
Embedded planetary reducer (including motor) shall be provided for driving 
speed reducer. 

Crawler tension device consists of tension oil cylinder, guide wheel and oil 
cup,  etc.  It  is  used  to  maintain  certain  tensity  of  crawler  by  adopting 
lubricating grease. 

2.2 Engine system 

As  power  source  of  the  entire  system,  engine  system  includes  engine, 
water  heat  dissipater,  air  filter  and  muffler,  etc.  D6114  pressurized 
water-cooled engine of Shanghai Diesel Engine Co., Ltd shall be selected 
and its rated power is 140kW/2300r/min. 

2.3 Power head
