Description
Technical field
The present invention relates to underground construction equipment field, specially a kind of band can open and close type bottom baffle augers.
Background technique
Traditional augers is when being applied to the unconsolidated formations such as weak soil, mud, sand ground since drill bit bottom is not enough
Resistance or block measure, drill bit extraction when, the sandstone being attached on drill bit are easy to drop back into hole；Moreover, because boring
Head mends slurry difficulty up and down, and drill bit be easy to cause the vacuum phenomenon of hole bottom when extracting out, thus the problems such as causing shrinkage cavity.
Summary of the invention
The purpose of the present invention is to provide it is a kind of can be applied to the unconsolidated formations such as weak soil, mud, sand ground, avoid drill bit from taking out
When out hole occur vacuumizing phenomenon band can open and close type bottom baffle augers.
In order to achieve the above object, the present invention is implemented as follows:
A kind of band can open and close type bottom baffle augers, it includes the drill bit body of rod with screw blade, is set to
The centring sleeve and cutter tooth of drill bit bottom；It further include tubular side baffle and the horizontal baffle set on tubular side baffle bottom；Tubular side
It is fixed at drill bit post to baffle, at least two layers of horizontal baffle, is equipped with opening, horizontal baffle passes through relative rotation
Two realize opening or closing for opening.
The band can open and close type bottom baffle augers, horizontal baffle includes middle baffle, lower baffle plate；Lower baffle plate water
Plane section moulding is identical as the horizontal cross-section moulding of tubular side baffle, and plate face is equipped with an opening, and lower baffle plate rotation is connected to drilling rod
Bottom is simultaneously located at tubular side baffle bottom, and middle baffle rotation is connected between tubular side baffle and lower baffle plate, middle plate washer and lower gear
Plate is set to below lower baffle plate for controlling opening or closing for drill bit bottom opening, centring sleeve, and cutter tooth is set to lower baffle plate opening；
Middle baffle bottom surface is equipped with arc groove, and lower gear plate top surface is equipped with convex block, and the convex block is set in arc groove, tubular side baffle bottom
Face, lower block plate top surface are equipped with one group with the limited block with baffle rotating distance in limitation.
The band can open and close type bottom baffle augers；Set on lower baffle plate opening there are two, symmetrically open up
In on lower baffle plate.
The band can open and close type bottom baffle augers；The drill bit body of rod is in hollow form；Centring sleeve, drilling rod wall are opened
Equipped with several through-holes.
The present invention uses above-mentioned design, is provided with the bottom baffle that can be closed, and can avoid soil when drill bit screws out and falls
It returns in hole, meanwhile, hollow drilling rod and through-hole with centring sleeve, on drilling rod is opened up, ensure that drill bit bottom hole when screwing out goes out
The phenomenon that now vacuumizing, the problem of so as to avoid shrinkage cavity.
