Abstract
The utility model discloses a drill rod with double powder discharging channels, which comprises a drill rod body. An air inlet channel and an air outlet channel are arranged in the drill rod body, and grooves are distributed on the side wall of the drill rod body. The drill rod body is provided with the air outlet channel, coal powder and gas are driven by air sent through the air inlet channel to be discharged from the air outlet channel, blockage is prevented and slag discharging is smooth since the air outlet channel is arranged inside the drill rod body. Slag can be discharged through the grooves arranged on the outer wall of the drill rod body when the drill rod is in operation. The coal powder and the gas can be simultaneously discharged through the air outlet channel and the grooves, and thereby slag discharging speed is increased, temperature deformation of the drill rod is reduced, and a deep drill hole protruding from coal bed is benefited.
Description
Technical field
The utility model belongs to the coal mining field, is specifically related to a kind of anti-outstanding drilling rod.
Background technology
In process of coal mining, before outstanding every layer exploited, need hole to projecting coal bed earlier, with the methane gas in the pump drainage coal seam.Rig is generally adopted in domestic projecting coal bed extraction boring, but often occurs collapsing phenomenons such as hole and boring obstruction in the process of creeping into, and causes the boring slagging channel to stop up, and then phenomenons such as bit freezing, drilling rod temperature distortion occur.Therefore, the gun drilling in coal seam is very difficult.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of deslagging unobstructed, on-deformable drilling rod with double powder passage.
The technical solution of the utility model realizes in the following manner: a kind of drilling rod with double powder passage, comprise the drilling rod body, and be provided with air intake passage and air-out passage in the drilling rod body, have a groove on the described drilling rod body sidewall.
Described groove shape or linearity in the shape of a spiral is distributed on the drilling rod body sidewall.
Described drilling rod body sidewall is provided with raised line.
The cross section of described raised line is circle or rectangle or ellipse or triangle.
The utility model drilling rod body is provided with the air-out passage, inwardly blows by air intake passage during work, and wind drives coal dust, methane gas is discharged from the air-out passage.Because the air-out passage is arranged on the drilling rod body interior, so clogging can not occur, deslagging is more unobstructed; On drilling rod body outer wall, be provided with groove, at also outside deslagging of when work groove.Coal dust and methane gas can have been accelerated deslagging speed from air-out passage and groove simultaneously to effluxing, and have reduced the temperature deformation of drilling rod, help projecting coal bed gun drilling.In addition, be provided with after the raised line, can improve deslagging speed simultaneously from space, air-out passage, groove deslagging between raised line and the drill hole wall.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.
Fig. 3 is the cross-sectional schematic of the utility model embodiment 2.
Fig. 4 is the cross-sectional schematic of the utility model embodiment 3.
The specific embodiment
As depicted in figs. 1 and 2, present embodiment comprises drilling rod body 1, is provided with air intake passage 3 and air-out passage 2 in the drilling rod body 1, and linearity is distributed with groove 4 on described drilling rod body 1 sidewall.Described linearity distributes and is meant along the axial directional distribution of drilling rod body 1.Drilling rod body two ends are provided with external screw thread in the utility model, link to each other by anchor ear between adjacent two drilling rod bodies.
Described air intake passage 3 can be arranged on the center of drilling rod body 1, also can not be arranged on the center.
Present embodiment further groove 4 also in the shape of a spiral shape be distributed on drilling rod body 1 sidewall.
As shown in Figure 3, described drilling rod body 1 sidewall is provided with the raised line 5 parallel with groove 4, and the cross section of raised line 5 is circular.If groove 4 linearly distributions, the also linearly distribution of raised line 5, if groove 4 shape distribution in the shape of a spiral, raised line 5 is shape distribution in the shape of a spiral also.
As shown in Figure 4, described drilling rod body 1 sidewall is provided with the raised line 5 parallel with groove 4.The cross section of described raised line 5 is a rectangle.Described raised line 5 is arranged on the band steel on drilling rod body 1 sidewall, and band steel is welded on the drilling rod body.Other structures are with embodiment 1.
