In the present application, for the purpose of clearly describing the positional relationship of the components, the terms of orientation such as "upper", "lower", "left" and "right" are used, and these terms of orientation are referred to the arrangement positions of the above drawings.
As shown in figure 1, the invention comprises an intermediate joint, a drill rod sealing mechanism, a drainage and slag discharge mechanism and an orifice connecting pipe; the middle joint 12 is a three-way pipe and is provided with a straight pipe and a side wall opening, the inner wall of the left pipe orifice of the straight pipe is provided with a sealing section flange 6, the inner wall of the right pipe orifice is provided with an orifice flange 11, and the side wall opening is connected with a drainage slag discharging mechanism; the sealing section flange 6 is provided with a drill rod sealing mechanism, and the orifice flange 11 is provided with an orifice connecting pipe 10.
as shown in fig. 2, the present invention is used in the following manner: the drill rod 13 penetrates through the drill rod sealing mechanism, the middle joint straight pipe and the orifice connecting pipe and extends into the drill hole, and the orifice connecting pipe 10 is attached to the hole wall to seal the orifice of the drill hole; in the drilling process, drilling cuttings generated by drilling enter the intermediate joint 12 from a gap between the orifice connecting pipe 10 and the drill rod, and the drill rod sealing mechanism blocks a gap on the periphery of the drill rod to prevent dust leakage; the drainage and slag removal mechanism arranged on the side wall of the middle joint 12 has a suction function and sucks away dust.
As shown in fig. 1 and 2, the drill rod sealing mechanism includes an outer tube 8, an outer side sealing ring 9 and an inner side sealing ring 7, the outer tube 8 is fixedly connected with the sealing section flange 6, and the inner wall of the outer tube 8 is provided with the outer side sealing ring 9 and the inner side sealing ring 7 for blocking a second fluid passage II between the outer tube 8 and the drill rod 13. The outer seal ring 9 and the inner seal ring 7 use gray rings.
As shown in fig. 1, the drainage and slag discharging mechanism comprises a slag discharging pipe 1, an end flange 2, an air pipe joint 3, a drainage pipe 4 and an air guide pipe 5; the top surface welded fastening is gone up with end flange 2 to the 1 outer wall of scum pipe, and 4 suits of drainage tube are in scum pipe 1 periphery, and bottom surface welded fastening is down with end flange 2 to the drainage tube, and the welding of tuber pipe joint 3 is on drainage tube 4, the lower part of 5 outer wall threaded connection drainage tubes 4 of guide duct, and 5 underpart of guide duct are on the lateral wall opening of intermediate head 12: the central pipeline of the slag discharging pipe 1 forms a first fluid channel I, the central pipeline of the air guide pipe 5 forms a third fluid channel III, a tapered seam with an upward opening is reserved between the top of the air guide pipe 5 and the bottom of the slag discharging pipe 1 to form a fourth fluid channel IV, a fifth fluid channel V is formed by a gap between the drainage pipe 4 and the outer wall of the slag discharging pipe 1, and a sixth fluid channel VI is formed by the central pipeline of the air pipe joint 3.
the orifice connecting pipe 10 is connected with the orifice flange 11 by welding.
