Hole.Upper mounted plate and bottom plate are all bar shapeds, and narrow, do not influence circulation of the air-flow in drilling pipe as far as possible.
As shown, the rotation by drill bit can carry out shoveling operation (being now in the first relative position).Work as rotation
When being loaded with soil on blade, drill bit is promoted, and is moved to side, drives the first and second motor that sliding unit is made to be in the later
Two relative positions, and blower is opened, to purge the soil of a part.Sliding unit is set to be in third relative position again later,
And blower is opened, to purge the soil of remainder.It can make drill bit reciprocating rotary during purging, fall to increase
Native effect.Due to purging every time, only expose first through hole or the second through-hole, the first and second through-hole is as venthole, due to real every time
The venthole negligible amounts that border uses, therefore the air-flow purged is strong, purging effect is good.Due between helical blade and air inlet
Distance is longer, is actually discontiguous between air inlet and the soil dug during shoveling.And when some soil fall
When dropping down onto drilling pipe, if the soil in drilling pipe more will affect operation.So as to so that sliding unit is in the first relative position, and
Electromagnet portion is opened, and opens blower, so that native slag is fallen from the bottom end of drilling pipe.
The drill bit that drilling machine of the invention uses (inclines in the operation for falling the soil on helical blade without tilting drill bit
Oblique drill bit is relatively time-consuming), to save the time, increase working efficiency.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
