Wherein: 1-driving head; 2-fixed cover; 3-fairlead; 4-helical blade drilling rod; 5-earth discharging hole.
Detailed description of the invention
The utility model is mainly used in the underground underground pipeline, soft area seedling growth of arranging of road secondary and digs that cave is dug in cave, animal raising rail fence pile anchoring, the occasion such as cave, fruit tree forest fertilization is dug in grape pepper plantation pile anchoring.
The basic structure of existing spiral drilling machine comprises driving head 1, helical blade drilling rod 4 and drill bit etc., driving head 1 comprises housing and power output shaft etc., helical blade drilling rod 4 upper ends are connected with the power output shaft of driving head 1, helical blade drilling rod 4 lower ends are connected with drill bit, and power output shaft can be hollow core shaft.
Embodiment mono-:
As Fig. 1, spiral drilling machine of the present utility model has increased coaxial with helical blade drilling rod 4 and has been positioned at the fairlead 3 of the tubular of helical blade drilling rod 4 outsides on the basis of existing basic structure, the top edge of fairlead 3 is fixedly connected with the housing of driving head 1, drill bit stretches out the lower limb of fairlead 3, offers earth discharging hole 5 on fairlead 3.
When use, drill bit creeps into earth downwards, because fairlead 3 is fixedly connected with the housing of rig head, fairlead 3 is along with creeping into of drill bit also stretched into earth, and earth plays friction to moving fairlead 3 and hinders, fixes effect anti-bias, positioning and guiding, prevents that drill bit from arbitrarily tilting, ensure directional drilling, improve drilling quality, without manpower righting, rapid operation.In addition, the earth in fairlead 3, along with the rotation of helical blade is upwards taken out of, prevents that earth discharge is not thorough, and without labor cleaning, cost of investment uses manpower and material resources sparingly.
Preferably, above-mentioned earth discharging hole 5 is positioned at the first half of fairlead 3.Earth discharging hole 5 setting positions are too low, and when being bored into after certain depth, earth discharging hole 5 is easily blocked the soil causing in fairlead 3 and cannot discharge.
