摘要:
本发明涉及一种新型链式钻头,包括位于钻杆下部且呈首尾连接的环形链条,所述的环形链条能由驱动机构驱动进行周向转动且该驱动结构位于钻杆下部,所述的环形链条的表面具有凸起结构;所述的环形链条至少有两条,且至少有两条环形链条的轴心线相互垂直。
摘要(英):
The invention relates to a novel chain type drill bit. The novel chain type drill bit comprises at least two end-to-end annular chains which are located on the lower portion of a drilling rod, the annular chains can be driven by a driving mechanism to rotate circumferentially, the driving mechanism is located on the lower portion of the drilling rod, and protruding structures are arranged on the surfaces of the annular chains; the central axes of the at least two annular chains are mutually perpendicular.
