Description
Technical field
This utility model relates to technical field of engineering machinery, and especially a kind of cubic metre of earth and stone bores and digs device.
Background technology
At present, along with the fast development of construction industry, the brill of the earthwork or the cubic meter of stone is dug operation by job site and is changed into churning driven machine drill gradually by traditional hand digging and dig；In operation process, rotary drilling rig is by moment of torsion and pressure transmission to drilling rod, and drilling bucket is used for accepting moment of torsion and pressure, thus realizing self rotation and feeding, and tunnels cutting dirt bed or lithosphere in this way；Therefore, drilling rod and drilling bucket play an important role in the earthwork or cubic meter of stone during drilling operations, are one of the vitals of rotary drilling rig.But, existing drilling rod and drill bit are very reasonable due to structural design, and there are the following problems to cause its inconvenience: when 1, the carrying out of earth harder in the cubic metre of earth and stone or the rock of part air slaking being crept into, and drilling effect is poor, brill odontotripsis is comparatively serious；2, cannot quickly and swimmingly by the earth got out or stone riprap discharge, have a strong impact on the work efficiency of rotary drill digging machine.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is in that providing the cubic metre of earth and stone that a kind of simple and compact for structure, drilling effect is notable, earth and stone riprap can be made to be discharged smoothly to bore digs device.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of cubic metre of earth and stone bores and digs device, it includes drilling rod, is installed in the drill bit of the head end of drilling rod and in axial direction through the medium tube in drilling rod and drill bit, and described drill bit includes main shaft part, be in axial direction formed at the two panels inward turning cutter portion of the edge of the head end end face of main shaft part, the pick cutter portion that is radially installed on the tail end sidewall of main shaft part and the two panels outward turning cutter portion being spirally distributed on the head end sidewall of main shaft part；
Being inlaid with at least one jet blower being connected for output high-pressure gas or highly pressurised liquid with the head end of medium tube on the sidewall of described main shaft part, described jet blower is positioned at the front face side in outward turning cutter portion and offsets with the front face in outward turning cutter portion.
Preferably, on the outer side surface in described outward turning cutter portion the first cutter tooth of several stepped distributions, it is formed with along the tail end in outward turning cutter portion to head end direction.
Preferably, on the front face in described pick cutter portion and side wall surface is provided with the second cutter tooth.
Preferably, on the sidewall of described drilling rod several pick sheets, radially it are additionally provided with.
Owing to have employed such scheme, this utility model utilizes inward turning cutter radical first to carry out contacting to carry out primary drilling with dirt bed or lithosphere, then outward turning cutter portion then can smash the sidewall of boring to pieces and cause that boring expands, hack or rubble are then derived by pick cutter portion from boring, realize the brill of the earth in the earthwork or the cubic meter of stone or rock is dug function with this；In whole during drilling operations, that can pass through medium tube and jet blower coordinates the scope of operation conveying high-pressure gas to drill bit or highly pressurised liquid, so that drill bit to be lowered the temperature, thus reducing the degree of wear of drill bit；Its simple in construction, effectively the earthwork or the cubic meter of stone can be carried out brill and dig, there is very strong practical value and market popularization value.

Fig. 2 is the structural representation of the drill bit of this utility model embodiment；
Fig. 3 is this utility model embodiment carrying out the view bored when digging operation.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
As shown in Figure 1 to Figure 3, a kind of cubic metre of earth and stone that the present embodiment provides bores and digs device, and it includes drilling rod 1, is installed in the drill bit of the head end of drilling rod 1 in the way of ring flange connection and in axial direction through the medium tube 2 in drilling rod 1 and drill bit；Wherein, drill bit includes main shaft part 3, is in axial direction formed at the two panels inward turning cutter portion 4 of the edge of the head end end face of main shaft part 3, the pick cutter portion 5 being radially installed on the tail end sidewall of main shaft part 3 and the two panels outward turning cutter portion 6 being spirally distributed on the head end sidewall of main shaft part 3；Meanwhile, being inlaid with at least one jet blower 7 for output high-pressure gas or highly pressurised liquid that is connected with the head end of medium tube 2 on the sidewall of main shaft part 3, jet blower 7 is positioned at the front face side in outward turning cutter portion 6 and offsets with the front face in outward turning cutter portion 6.So, after drill bit bears the moment of torsion and pressure being transmitted out by drilling rod, self rotation and feeding can be carried out under the drive of drilling rod 1, and at this moment, first inward turning cutter portion 4 can carry out with dirt bed or lithosphere contacting to realize at the primary drilling broken ground or in broken stone process, then when the continuous feeding of drill bit, outward turning cutter portion 6 then can smash the sidewall of boring to pieces and cause that boring expands, again through the effect in pick cutter portion 5, hack or rubble are derived from boring subsequently, realize the brill of the earth in the earthwork or the cubic meter of stone or rock is dug function with this；In whole during drilling operations, that can pass through medium tube 2 and jet blower 7 coordinates the scope of operation conveying high-pressure gas to drill bit or highly pressurised liquid, with to drill bit, especially revolve cutter and lower the temperature, thus reducing the degree of wear of drill bit.
Brill for strengthening whole drill bit digs performance, to greatest extent to pieces dirt bed or lithosphere being smashed process, is formed with the first cutter tooth 8 of several stepped distributions on the outer side surface in outward turning cutter portion 6, along the tail end in outward turning cutter portion 6 to head end direction.
Rubble or hack for enabling formation are successfully discharged in boring, are provided with the second cutter tooth 9 on the front face in pick cutter portion 5 and on side wall surface.
As a preferred version, on the sidewall of drilling rod 1, radially it is additionally provided with several pick sheets 10, to utilize pick sheet 10 to accept pick cutter portion 5, makes rubble or hack discharge.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
