Abstract
The utility model discloses an improved drilling rod on a drilling machine. The utility model is characterized in that a through hole is arranged in the drilling rod (3); an air source inlet and a water source inlet are arranged on the joint (2); the air source inlet and the water source inlet are communicated with the through hole in the drilling rod (3); the air source inlet and the water source inlet are respectively communicated with respective source heads (5) and (6) through a pipeline; the source heads (5) and (6) are respectively communicated with a water supply system and an air supply system; switches (7) and (8) are respectively arranged on the air source inlet and the water source inlet. Because in the utility model, the through hole is arranged in the drilling rod and the utility model is provided with an air source and a water source, operation can be carried out on a dry coal bed and a moist coal bed and the work efficiency is improved. According to the drilling machine which is manufactured according to the proposal of the utility model, the utility model can supply positive using effect on coal mine industry.
Description
Technical field: the utility model is related is a kind of improvement invention that is used to exploit the rig in colliery, and what be specifically related to is the improvement invention of drilling rod on a kind of rig, particularly be a kind of hollow drill that is provided with water source import and gas source inlet.
Background technology: the drilling rod on the employed rig of prior art all is not provided with source of the gas and water source, the drilling rod of not establishing source of the gas and water source is in the process of coal mining, during special comparatively dry coal seam, drilling rod runs up and with the coal seam of being drilled friction takes place and can generate heat, ickings can get lodged on the lines of drilling rod, and make drilling rod and the coal seam drilled between friction factor clamp the friction factor that drilling rod produces greater than the main frame chuck, and the bit freezing phenomenon often appears, the application life of main motor can be influenced, also operating efficiency can be reduced.
Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of simple in structure, and is reasonable in design, and can make drilling rod rig of bit freezing not under the long-term operation user mode.In order to achieve the above object, the utility model is finished by following mode: the utlity model has main frame and frame, on described main frame, be provided with joint, drilling rod is installed on the joint, described drilling rod is a twist drill rods, drilling rod is provided with drill bit, it is characterized in that being provided with through hole in the described drilling rod, described joint is provided with gas source inlet and water source import, through hole in described gas source inlet and water source import and the drilling rod communicates, described gas source inlet and water source import communicate with separately source by pipeline respectively, and described source is connected with water system and air supply system respectively, is respectively equipped with switch in described gas source inlet and water source import.Described drilling rod is the combined type drilling rod, and an end of described drilling rod is provided with square groove, and the other end is provided with the projection that is complementary with this groove.Be provided with a small lugs in the one end square groove of described drilling rod, be provided with the little groove that is complementary with small lugs in the projection that the other end and this groove are complementary, in described little groove, be provided with sealing ring.The utility model is owing to be provided with through hole in drilling rod, and is furnished with source of the gas and water source, therefore, can satisfy simultaneously in dry and moistening coal seam and carry out operation.And improved operating efficiency greatly, and because the groove in the drilling rod is square, the projection that is complementary with this square groove also is square, therefore the drilling rod of respectively combining is passed in and out synchronously.According to the rig of the utility model theme made, bring positive result of use will for the colliery extraction industry.
Description of drawings: the utility model has following accompanying drawing;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model jackrod structure sectional view.
The specific embodiment: accompanying drawing has been represented structure of the present utility model and fact Example thereof, further describes the related content and the operating principle of embodiment below more in conjunction with the accompanying drawings.The utlity model has main frame 1 and frame 11, on described main frame 1, be provided with joint 2, drilling rod 3 is installed on the joint 2, described drilling rod 3 is a twist drill rods, drilling rod 3 is provided with drill bit 4, be provided with through hole in the described drilling rod 3, described joint 2 is provided with gas source inlet and water source import, described gas source inlet and water source import communicate with through hole in the drilling rod 3, described gas source inlet and water source import communicate with separately source 5,6 by pipeline respectively, described source is connected with water system and air supply system respectively, is respectively equipped with switch 7,8 in described gas source inlet and water source import.Described drilling rod 3 is the combined type drilling rod, combine by each unit drilling rod, one end of described each drilling rod 3 is provided with square groove 10, and the projection 9 that the other end is provided with 9, one the unit drilling rods of projection that are complementary with this groove matches with the groove 10 of another unit drilling rod.Be provided with a small lugs 13 in the one end square groove 10 of described drilling rod, be provided with the little groove 12 that is complementary with small lugs in the projection 9 that the other end and this groove 10 are complementary, in the little groove 12 of described each unit drilling rod, be provided with sealing ring.The utility model sets the length of drilling rod 3 earlier according to the cutting depth in coal seam when the work of the coal seam of drying, start main motor 1, drilling rod 3 is rotated, and open water source switch 8 simultaneously, closes gas source switch 7.Water inlet system can by import enter into the through hole of drilling rod 3 in from pipeline water, water can be along through hole from drill bit 4 exit flow out, therefore in drilling process, drilling rod 3 is in the water cooling state for a long time, just can not be because of heating increase friction factor between drilling rod and the coal seam, and the bit freezing phenomenon that occurs.So cinder will be discharged outside the coal seam along the screw thread of drilling rod easily.
When the utility model is worked in moistening coal seam, start main motor 1, drilling rod 3 is rotated, open gas source switch 7 then, close water source switch 8,, therefore do not need the source switch of fetching boiling water owing to carry out work in moistening coal seam.Air supply system can enter into air in drilling rod 3 through holes by import from pipeline, and blows out along the exit at through hole other end drill bit 4 positions in the drilling rod 3, so cinder will be discharged outside the coal seam by the screw thread along drilling rod owing to action of air pressure.
The utility model also can be opened the switch at source of the gas and water source simultaneously, make cinder discharge the coal seam along the screw thread of drilling rod fast, the utility model is reasonable in design, and is simple in structure, brings positive result of use will for the colliery extraction industry according to the rig of the utility model theme made.
