Abstract
The utility model discloses a dual-purpose drilling tool, which relates to a tool for water well drilling and belongs to the drilling field for fixed constructions. The drilling tool comprises a connecting shank (1), a drill pipe (5) and drill rods (7), and is characterized in that the drill pipe (5) is a round pipe, the upper end of the round pipe is a pipe cover (2), the center of the pipe cover (2) is provided with a square hole, the lower end of the connecting shank (1) penetrates into the square hole of the pipe cover (2) to be in threaded connection with the drill pipe (5), the outer side of the lower end of the drill pipe (5) is sleeved with a thickened hoop (6), and the drill rods (7) are welded on the thickened hoop (6). The utility model resolves the problem that the well-drilling core bit is inconvenient for drilling holes due to over-length of the core bit in case of drilling, and can not drill in case of rocks, which easily damages the core bit.
Description
(1) technical field
The utility model relates to a kind of sink wells instrument, belongs to the field of creeping in the fixed buildings.
(2) background technology
The patent No. is the utility model patent well-digging core bit of ZL2007 2177799.7; a kind of new well-digging drilling tool is disclosed; changed when well-digging ran into water layer in the past; because the sandstone of getting etc. can not take out; mud is stuck with paste block water layer to be unfavorable for the problem of digging a well; but this drilling tool one is when perforate because oversize inconvenient perforate can not get through when running into stone on the other hand, causes drilling tool to damage easily.
(3) summary of the invention
The purpose of this utility model provides a kind of dual-purpose drilling tool that perforate also can operate as normal when running into stone that makes things convenient for, and is used with the well-digging core bit of ZL2007 2177799.7D.
The purpose of this utility model is achieved in that
Dual-purpose drilling tool, comprise catcher (1), drilling pipe (5) and drill rod (7), it is characterized in that drilling pipe (5) is a pipe, there is pipe lid (2) its upper end, there is a square hole at the position, the center of circle of pipe lid (2), and the lower end of catcher (1) is deeply managed in the square hole of lid (2) and is threaded with drilling pipe (5), along diametric(al) two relative stirring steel plates (4) is arranged on drilling pipe (5) inwall, the outside, lower end of drilling pipe (5) is with thickening hoop (6), is welded with drill rod (7) on the thickening hoop (6).
The utility model has the advantages that: drilling tool has adopted said structure, makes drill rod (7) under the drive of drilling tool power when work, and repeated stock up and down can make things convenient for perforate and smash stone, works on the well-digging core bit then.
(4) description of drawings
Fig. 1 is the elevation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 1.
(5) specific embodiment
Dual-purpose drilling tool, comprise catcher (1), drilling pipe (5) and drill rod (7), it is characterized in that drilling pipe (5) is a pipe, there is pipe lid (2) its upper end, there is a square hole at the position, the center of circle of pipe lid (2), and the lower end of catcher (1) is deeply managed in the square hole of lid (2) and is threaded with drilling pipe (5), along diametric(al) two relative stirring steel plates (4) is arranged on drilling pipe (5) inwall, the outside, lower end of drilling pipe (5) is with thickening hoop (6), is welded with drill rod (7) on the thickening hoop (6).
There is hold-doun nut (3) lower end of catcher (1).
When work, the utility model drilling tool makes drill rod (7) under the drive of drilling tool power, repeated stock up and down, can make things convenient for perforate and smash stone, stir steel plate (4) and play stirring action, finishing perforate and pounding stone of task works on the well-digging core bit then.
Claims (2)
1, dual-purpose drilling tool, comprise catcher (1), drilling pipe (5) and drill rod (7), it is characterized in that: drilling pipe (5) is a pipe, there is pipe lid (2) its upper end, there is a square hole at the position, the center of circle of pipe lid (2), and the lower end of catcher (1) is deeply managed in the square hole of lid (2) and is threaded with drilling pipe (5), along diametric(al) two relative stirring steel plates (4) is arranged on drilling pipe (5) inwall, the outside, lower end of drilling pipe (5) is with thickening hoop (6), is welded with drill rod (7) on the thickening hoop (6).
