Abstract
The utility model belongs to the technical field of a mining device, and in particular to an air-type slag stopping device of a drilling machine. The air-type slag stopping device comprises a slag stopping plate which is connected with a guide sleeve on a drilling rod, wherein the slag stopping plate is arranged inside a dust removal housing of the drilling machine, and the air-type slag stopping device is characterized in that the slag stopping plate is obliquely arranged on one side inside the dust removal housing, the upper end of the slag stopping plate is fixedly connected with the guide sleeve, the lower end stays at a cantilever state, the other side inside the dust removal housing is provided with an air blowing pipe, and the air blowing pipe penetrates the side wall of the dust removal housing to be connected with an air blower. An angle alpha formed between the lower surface and the vertical surface of the slag stopping plate is 110 to 120DEG. A gap between the drilling rod and a platform is sealed through the added air blower and the high-pressure air generated in the horizontal direction, so that rock slag can be prevented from entering the platform, the on-site working environment can be protected, the labor intensity of employees can be alleviated, the fault rate of the drilling machine can be reduced, and a purpose of high efficiency and low cost of the machine can be realized.
Description
Technical field
The utility model belongs to the technical field of winning equipment, especially relates to a kind of rig wind formula skimming device.
Background technology
Rig is the capital equipment that mining is produced.During rig perforation operation, drilling rod produces gyration and axially-movable with virtual calibrator for instrument transformer and drill bit, and drill bit creeps into and turns round in bottom, operation hole, and bottom, operation hole is produced static pressure and impacts the dynamic pressure effect.Drill bit pushes in rolling in bottom, operation hole continuously, the cutting-impact fractured rock, meanwhile, compressed air with elevated pressures and high flow capacity flow velocity is through the steam vent ejection from drill bit of drilling rod and virtual calibrator for instrument transformer, the annular space of rock quarrel from bottom, operation hole along virtual calibrator for instrument transformer, drilling rod and operation hole hole wall constantly blown to the hole, until form the boring of required hole depth.
Continue to be cut from a large amount of rocks that discharge bottom, operation hole during rig perforation operation.It is slag trap that existing rotary drill has special-purpose slag pushing equipment, be placed in the dust-collecting hood, be enclosed within on the drilling rod, sternly cooperate with drilling rod, suspension is fixed on the platform inboard, and it act as passing through that pressure wind is discharged when blocking drill hole of drilling machine, and the space blows out extraneous rock slag between platform fairlead and the drilling rod.The pushing off the slag acting duration of finding slag trap in the practical application is short.Its reason is that slag trap is made by rubber, and rubber tile is not wear-resisting, and the drill rod abrasion that several classes get off and just are rotated, internal diameter become large, strengthen with the drilling rod fit clearance.The result causes the rock slag by going out in the fit clearance and spanning platform, and related consequence is: contaminated environment, affect post worker's physical and mental health; Contaminated equipment, each chain that destroys equipment, axle tooth, the lubricated and application life of destroying rotary part; 1.5 hours flush equipment of each class need, put the oil, root out and be deposited in the about 150 jin accumulated slag of platform; Each class will consume 1 cubic metre water for dust removal service equipment.
Summary of the invention
The utility model provides a kind of rig wind formula skimming device, solves the rock slag from the problem of fairlead and drilling rod gap spanning platform top, reduces the infringement to equipment, improves gear wheel efficient.
The purpose of this utility model realizes by following technical proposals:
Rig wind formula skimming device of the present utility model, comprise the slag trap that is connected with fairlead on the drilling rod, this slag trap is positioned at the dust-collecting hood of rig, it is characterized in that described slag trap is to be in tilted layout that a side and upper end in dust-collecting hood is fixedly connected with described fairlead, the lower end becomes cantilever position, opposite side in the described dust-collecting hood is provided with blower, and this blower passes the dust-collecting hood sidewall and is connected with a blast fan.
The angle α of the soffit of described slag trap and vertical plane is 110-120 °.
Advantage of the present utility model:
1) the utility model seals drilling rod and platform gap by the high-pressure blast that increases blast fan, generation horizontal direction, avoid the rock quarrel to enter on the platform, working environment keeps the scene intact, be conducive to improve the rig operating rate, alleviated post worker's labour intensity, reduced the fault rate of rig, realized that board is efficient, the purpose of low cost movement;
2) the utility model is by changing the inclination angle of slag trap and vertical plane, and the guiding rock slag direction of motion guarantees not have in the dust-collecting hood rock slag to be detained the dead angle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, rig wind formula skimming device of the present utility model, comprise the slag trap 5 that is connected with fairlead 4 on the drilling rod 3, this slag trap 5 is positioned at the dust-collecting hood 6 of rig, it is characterized in that described slag trap 5 is for a side and the upper end in dust-collecting hood 6 of being in tilted layout is fixedly connected with described fairlead 4, the lower end becomes cantilever position, opposite side in the described dust-collecting hood 6 is provided with blower 2, and this blower 2 passes dust-collecting hood 6 sidewalls and is connected with a blast fan 1.Blast fan 1 is installed on the platform, and blower 2 is rectangular tube, and inserts in the dust-collecting hood 6, and the wind outlet is carried out cross blowing facing to the root of fairlead 4 to drilling rod 3, and this cross blowing prevents that the rock quarrel from moving upward,
The angle α of the soffit of described slag trap 5 and vertical plane is that 110-120 ° of slag trap is equivalent to verge board change wind direction, stops that the rock slag enters the top dead angle area in the dust-collecting hood.
Claims (2)
1. rig wind formula skimming device, comprise the slag trap that is connected with fairlead on the drilling rod, this slag trap is positioned at the dust-collecting hood of rig, it is characterized in that described slag trap is to be in tilted layout that a side and upper end in dust-collecting hood is fixedly connected with described fairlead, the lower end becomes cantilever position, opposite side in the described dust-collecting hood is provided with blower, and this blower passes the dust-collecting hood sidewall and is connected with a blast fan.
2. rig wind formula skimming device according to claim 1 is characterized in that the soffit of described slag trap and the angle α of vertical plane are 110-120 °.
