Description

Rock cylinder brill is worn in rotary pile-digging machine water filling

Technical field

The utility model is related to a kind of rotary pile-digging machine, is specifically related to one kind and wears rock cylinder brill lower end provided with note in rotary pile-digging machine Rock cylinder brill is worn in the water filling of aquaporin.

Background technology

The various model rotary pile-digging machines used at present, once running into rock stratum during borehole, rock is worn using various drilling tool All highly difficult, " water filling becomes the multi-functional rock of wearing of tooth and bored " of Patent No. 201420218217.5 is although digging rock can be bored comparatively fast safely The heart, but when running into granite or extremely hard limestone in its reaming procedure after, its reaming efficiency is not satisfactory.Using common Cutter barrel is bored and bullet-type cylinder is bored, because its one-time continuous rock drilling depth is reached after 20cm or so, it is necessary to is suspended rock drilling and is allowed brill Laugh somebody to scorn but, if not cooling and continuing deep drilling, because of the clogging drill flute of rock ballast and stone flour in drill flute, make current in stake holes not It can go downwards at brill tooth, thus cause brill tooth dry friction, temperature is drastically raised, and ultimately resulting in brill tooth intensity rapidly reduces, quickly Abrasion, therefore its rock drilling cost is high, and rock speed is worn in influence.

The content of the invention

The purpose of this utility model is to be directed to the above-mentioned deficiency for wearing rock instrument, and a kind of cost proposed is low, wears rock operation Speed is fast, safe and reliable, and rock cylinder brill is worn in the easy rotary pile-digging machine water filling of maintenance.

Technical solution of the present utility model is：The upper end of tank center's rotating shaft is fixed on by telescopic drill rod socket stretches On contracting drilling rod, tank center's rotating shaft inserts fixed in the square groove of cylinder upper end by the square toes of its lower end, the circumference of cylinder lower end On be fixed with brill tooth, the outer wall of cylinder along longitudinal direction be provided with waterflood path, the water jet of waterflood path is located at brill flank, in water The outer wall of case overcoat is provided with water pipe head.

High pressure is connected with the water pipe head on water tank outer casing outer wall described in technical solution of the present utility model Water supply hose, the other end of high-pressure water inlet flexible pipe is wrapped on the wind spring rotating disk outside stake holes mouthful.

High-pressure cooling water of the present utility model can be delivered at each brill tooth of dynamic rock drilling in time, therefore can make brill tooth Cooled in time, keep its intensity, fundamentally solve the problem of brill odontotripsis is fast；The utility model realizes cylinder and drilled Rock is smooth more rapidly；The utility model greatly reduces the consumption tooth cost for wearing rock, improves and wears rock operating speed and economic benefit, It is safe and reliable, the easy field of maintenance.
