Description

A kind of drilling machine side tool head of interchangeable cutter head

Technical field

It is main to use more particularly, to a kind of drilling machine side tool head of interchangeable cutter head the utility model is related to a kind of drill bit cutter head In earth drill leading portion drill bit, belong to the component in a kind of construction site earth drill.

Background technology

Long auger guncreting pile compared to impact drill, churning driven, mill bore etc. due to have quick, environmentally friendly, high capacity, The features such as economic, is widely used in the filling pile construction of various pile foundation engineerings, basement process and foundation pit supporting project.But by Its technology and equipment are limited, in large-sized crushed stone soil layer and weathered rock formation, there is the problems such as boring motionless, bit freezing and nothing Method construct, even if in indivedual similar stratum can pore-forming, construction efficiency is also very low, and cost is very high, is badly in need of at this stage A kind of a kind of drill bit that can be solved the above problems.

Common hard alloy class drill bit generally use monolithic construction, i.e., be not between knife bar and cutter head in existing market Removably, using being welded and fixed between knife bar and cutter head, the production cost for causing drill bit is high, and resource utilization is low, at present also Without reasonable in design, the high precision machining of one kind, cutter head can be given up, the drill bit cutter head of service life length.

Utility model content

The utility model is directed to the above-mentioned deficiency of the prior art, and hard ground plane apertures construction can be oriented in by providing one kind, And it is convenient for changing a kind of drilling machine side tool head of interchangeable cutter head of cutter head.

The drill bit side tool head of a kind of interchangeable cutter head, including bottom plate, operator head jack, it is characterised in that on the bottom plate uniformly Be distributed with multiple independent fixed columns, one end of the fixed column is fixed on one end of bit body, the bit body it is another End is provided with apex point, and main section and lateral incision face are carried on the apex point, and the main shear-face angle is directed toward the same center of circle, the fixation Locking slot is provided in column, one end of the bit body is provided with positioning bottom surface, and there are two the outer wall settings of the bit body Supporting surface, the positioning bottom surface and two supporting surfaces are planar structure.

Further, the independent fixed column is symmetrical with a jack center of operating, linear to be distributed.

Further, the independent fixed column close to the operator head jack, which is equipped with, turns to cushion block.

Further, the steering cushion block is equipped with cutter head, and the cutter head is horizontal by 30-45 degree.

Further, the locking slot is made of a bottom surface and two wall surfaces, axis of described two wall surfaces along fixed column It is arranged to direction, the oblique structure of described two wall surfaces, the distance between two wall surfaces gradually contract from groove top to slot bottom It is small.

Further, the fixed column is cylindrical structural.

Further, the side shear-face angle of the apex point is 30~150 degree.

The advantage of the utility model is：

（1）Simple with traditional drill bit structure compared, design is reasonable, and design is unique, interchangeable bit, service life It is long, it is set in the outer wall of bit body there are two supporting surface, it is planar structure to position bottom surface and two supporting surfaces, can be fine Fixed cutter head so that the rotation of cutter head it is more steady.

（2）The main same center of circle of shear-face angle direction of the utility model cutter head, the main bit at the hard ground of operation, because Because angle is directed toward the same center of circle, axle center is followed, which to rotate together, makes main section shearing force perform to maximum for all main sections of cutter head, And cutter head is protected to substantially reduce its degree of wear to the greatest extent.

（3）Side tool head is individually set up in main drill bit obliquely downward, stone can be disperseed, reduces hard soil to main drill bit Abrasion.
