For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of full screw earth auger, and it comprises chassis, hollow unit head, auger stem, drilling rod leading truck and brill mast, described hollow unit head is arranged at and bores on mast bottom or chassis.
The blade of described auger stem is provided with driver slot, and this driver slot coordinates with driving key on being arranged at the hollow unit head.
Described driver slot and the supporting setting of quantity that drives key, the driver slot on each helical blade (blade that refers to a pitch scope) arranges 2～9.
Described auger stem can slide along the quill shaft of hollow unit head, and both fit clearances are 2～12 ㎜.
Described driving key is distributed on the quill shaft of hollow unit head, perhaps is distributed in to be installed on
Quill shaftOn interior sleeve.
Described hollow unit head is by hydraulic motor or motor-driven.
Described drilling rod leading truck is connected with the auger stem top, and the drilling rod leading truck is matched in clearance with boring the mast slideway, can move up and down along boring the mast slideway.
Described brill mast is installed on walking or caterpillar chassis.
Further improve, above-mentioned blade is provided with the boss of alloy steel material, and described driver slot is opened on boss.
The beneficial effect that adopts technique scheme to produce is: the utility model is arranged at the bottom with the hollow unit head, thereby significantly reduce the position of centre of gravity of full screw earth auger, improve the job stability of full screw earth auger and the safety of construction operation, can satisfy again the output of unit head high pulling torque and large deep drilling.The utility model can also further reduce weight and the appearance and size of walking or caterpillar chassis, reduces manufacturing cost and cost of transportation, improves maximum drilling diameter and the drilling depth of long-spiral drilling machine.
