Description
Technical field
The present invention relates to a kind of the hole drill of pick be bored on the stratum, particularly a kind of beche hole drill that drives the constant gravity impact drill bit downwards of weight pick hole by air pressure.
Background technology
In general, in the process of building operations the stratum is bored the work of pick, must excavate the stratum by boring pick equipment, and the kind in domain has the difference of soft or hard according to the difference in zone, various places, particularly country in Southeast Asia (such as Malaysia) is the rock stratum that belongs to quite hard, especially bores and digs to such an extent that darker rock stratum can be harder.
" laccolite bores the pick device " patent of invention case that prior art such as TW patent announcement are I278559 number; The prior art is installed to this by the rotating power source transmission, and the pneumatic unit of the gravity that cooperate to bore pick device self and this device vibration mode up and down reciprocatingly, makes drill bit constantly bore pick in the downward shatter rock stratum of gravity impact; Device comprises: an adapter, the structure that provides rotary drive and air inlet to shake; One sleeve pipe, an end are incorporated into the lower end that is connected axle, and the joint that continues, and this joint is again in conjunction with a pneumatic unit, and this pneumatic unit and in conjunction with interlock one drill bit makes pneumatic unit drive drill bit and produces up and down reciprocatingly vibrations, the shatter rock stratum so can continue downward the bump.
But, in the process of the prior art practice of construction, its employed pressed gas also can't be used after the air inlet vibrations effectively again, cause the waste of electric power resource, and drill bit is broken into rubble after the rock stratum is clashed into, all rubble and mud water importing pick must be got in the device, the well of more whole device being deactivated, wait move on to rotated on one side after, this pick is got device and just can be opened and rubble and mud water are toppled over out fully, and so time-consuming operation not only can cause procrastinateing of duration, more seriously cause the raising of human cost, not being inconsistent in fact the engineering dealer needs the reduction of erection time and saves manpower, the construction requirement of material resources cost.
Summary of the invention
Main purpose of the present invention is to provide a kind of beche hole drill that air pressure can be recycled, and to solve the waste of prior art electric power resource, operation is time-consuming, not only can cause procrastinateing of duration, and causes the problem of the raising of human cost.
According to above-mentioned main purpose, the present invention proposes a kind of air pressure recycling formula beche hole drill technical scheme, described beche hole drill includes: one is subjected to external force to rotate and have the head that rotarily drives of admission line, and this rotarily drives head and is equipped with a second row stone extract duct; One covers at this rotarily drives head outward and has the outer cover that air inlet port is connected with this admission line, have in this outer cover one be connected with this second row stone extract duct put temporarily the space, and be provided with one in this outer cover and put temporarily row's stone air exit that the space is connected with this; And one can by this rotarily drive head drive and have that guide duct is connected with this admission line stretch into the earth's surface motor unit, and this stretches into the earth's surface motor unit and includes: a pneumatic hammer pipeline that is connected with this guide duct, and being provided with the pneumatic hammer piston of a hollow and a part in this pneumatic hammer pipeline, to stretch out this pneumatic hammer pipeline outer and be subjected to the drill bit of this pneumatic hammer piston slap action; One has that the return-air space is connected with this pneumatic hammer pipeline and the integration cover of affixed this pneumatic hammer pipeline; One be fixed in this integration cover and with this pneumatic hammer pipeline side by side row's madreporic canal road mutually, row's stone entrance of this row's madreporic canal road below connection one and exterior, the top then is communicated with a first row stone extract duct that is connected with this row's madreporic canal road, and this first row stone extract duct is connected with this second row stone extract duct again; One is arranged in the exhaust entrance that this integration cover is upper and be connected with this return-air space; And an extract duct that is communicated with this exhaust entrance and this first row stone extract duct, and this exhaust entrance has a non retern valve to this extract duct.
Further, described air pressure recycling formula beche hole drill, described stretch into the earth's surface motor unit also include one run through this integrations cover and with this pneumatic hammer pipeline phase side by side run through pipeline.
Further, air pressure of the present invention recycling formula beche hole drill, the described earth's surface motor unit that stretches into also includes one and is arranged in the auxiliary exhaust entrance that this integrations cover is gone up and is connected with this return-air space; An and auxiliary exhaust pipeline that is communicated with this auxiliary exhaust entrance and this first row stone extract duct, and the junction that this auxiliary exhaust pipeline is communicated with this first row stone extract duct is higher than the junction that this extract duct is communicated with this first row stone extract duct, and this auxiliary exhaust entrance has the auxiliary non retern valve that a position horizon height is higher than this non retern valve position horizon height to this auxiliary exhaust pipeline.
