Abstract
The utility model relates to a coupling drill housing for a mine pneumatic outburst-prevention driller, which is characterized in that a drill brushing (1) is a cylindrical body, one end of the cylindrical body is axially provided with a first inner square (1.1), the cylinder wall on one end of the cylindrical body is radially provided with a first bolt hole (1.2), and the first bolt hole (1.2) iscommunicated with the first inner square (1.1); the other end of the cylindrical body is axially provided with a second inner square (1.3), the cylinder wall on the other end of the cylindrical bodyis radially provided with a second bolt hole (1.4), and the second bolt hole (1.4) is communicated with the second inner square (1.3). The drill housing can be used in conjunction with various spiraldrill pipes. The spiral drill pipe not only can advance a borehole, but also can drill a water injection pore, a deep water pore and a gas drawing hole.
Description
(1) technical field
The utility model relates to a kind of mining pneumatic rigs against outburst, is specifically related to a kind of mining pneumatic rigs against outburst and connects drill bushing.Belong to mining boring field of mechanical technique.
(2) background technology
Before the utility model was made, traditional mining pneumatic rigs against outburst was not provided with drill bushing, therefore can only connect B19, B22 hexagonal hollow drill pipe, was used for driving boring.And can't in the coal seam, bore water injection hole, deep water hole and the hole that draws out methane.Therefore the scope of application is restricted.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of mining pneumatic rigs against outburst that can expand the mining pneumatic rigs against outburst scope of application to connect drill bushing.
The purpose of this utility model is achieved in that a kind of mining pneumatic rigs against outburst connects drill bushing, described drill bushing is a cylindrical body, one end of this cylindrical body axially is provided with four directions in one first, radially be provided with one first bolt hole on the one end barrel of this cylindrical body, described first bolt hole is connected with four directions in first, is used to connect the output main shaft of power part gear pump; The other end of this cylindrical body axially is provided with four directions in one second, radially is provided with one second bolt hole on the other end barrel of this cylindrical body, and described second bolt hole is connected with four directions in second, is used to connect auger stem.
The utility model drill bushing can be used with various auger stems.Auger stem not only can tunnel boring, and can bore water injection hole, deep water hole and the hole that draws out methane in the coal seam.Therefore can expand the mining pneumatic rigs against outburst scope of application greatly after adopting this coupling sleeve.And this drill bushing structure is simple, and is easy to manufacture, low price.
(4) description of drawings
Fig. 1 is that the mining pneumatic rigs against outburst of the utility model connects the drill bushing structure schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is an application implementation illustration of the present utility model.
Among the figure:
Drill bushing 1, nut 2, bolt 3, output main shaft 4, gear pump 5;
Four directions 1.1, first bolt hole 1.2, the second interior four directions 1.3, second bolt hole 1.4 in first.
(5) specific embodiment
Referring to Fig. 1～2, the utility model is mining, and pneumatic rigs against outburst connects drill bushing, described drill bushing 1 is a cylindrical body, one end of this cylindrical body axially is provided with four directions 1.1 in one first, radially be provided with one first bolt hole 1.2 on the one end barrel of this cylindrical body, four directions 1.1 is connected in described first bolt hole 1.2 and first; The other end of this cylindrical body axially is provided with four directions 1.3 in one second, radially is provided with one second bolt hole 1.4 on the other end barrel of this cylindrical body, and four directions 1.3 is connected in described second bolt hole 1.4 and second.
Referring to Fig. 3, Fig. 3 is an application implementation illustration of the present utility model.As seen from Figure 3, the output main shaft 4 of power part gear pump 5 connects with the first interior four directions of drill bushing 1 one ends by bolt 3, nut 2, and the second interior four directions of drill bushing 1 other end by its bolt hole, cooperates and can connect work with auger stem with bolt and nut.
