Abstract
The utility model relates to a hexagonal geological spiral drill stem device quick to connect and for coal mine tunnel drilling. The hexagonal geological spiral drill stem device structurally comprises a drill stem hexagonal male connector, a round drill stem body and a drill stem hexagonal female connector. The drill stem hexagonal male connector and the drill stem hexagonal female connector are welded at the two ends of the round drill stem body respectively through friction welding, and spiral blades are wound on the round drill stem body in a welding mode. The hexagonal geological spiral drill stem device is reasonable in design, compact in structure, convenient to operate, fast to connect and wide in range of application. Due to the fact that a hexagonal connecting mode is adopted in the drill stem connectors, torque and comprehensive mechanical performance of a drill stem under the condition of the same diameter reach the optimal allocation. The ultra-low spiral blade structural design is adopted, therefore, the purpose of rotary cinder discharging is achieved, and meanwhile, the phenomena of drill suction and drill stem blocking which are prone to being caused by a large spiral drill stem are avoided. Due to the fact that a horizontal drill stem spring locating pin is adopted in connection, disassembling and assembling are fast and convenient, time and labor are saved, and working efficiency is improved greatly.

The specific embodiment
With reference to the accompanying drawings embodiment of the present utility model is further described
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the fast ground connection matter auger stem device with six sides is drilled in tunnel, a kind of colliery, its structure comprises drilling rod six side's male joints 1, round drill rod body 3, drilling rod six side's female joints 5, twine on the described round drill rod body 3 and be welded with helical blade 2, described drilling rod six side's male joints 1 are connected with drilling rod six side's female joints 5 by round drill rod body 3, described drilling rod six side's male joints 1 are the outer hexagonal structure of hollow, the front end of described drilling rod six side's male joints 1 is provided with seal groove 14, the side of described drilling rod six side's male joints 1 is provided with semicircle cotter way 12, described drilling rod six side's female joints 5 are hexagonal structure in the hollow, described drilling rod six side's female joints 5 built-in sealing shrouds 4, described drilling rod six side's female joints 5 sides are provided with card beans pin-and-hole 6 and horizontal drilling rod dowel hole 7, be provided with horizontal drilling rod spring holder 13 in the described horizontal drilling rod dowel hole 7, described horizontal drilling rod spring holder 13 is by shank 8, card beans pin 11, back-moving spring 9 and pad 10 are formed;
Described drilling rod six side's male joints 1 and drilling rod six side's female joints 5 are welded on the two ends of round drill rod body 3 respectively by friction welding;
