Description
Technical field
This utility model relates to the drill bit of a kind of rotary pile-digging machine, particularly relates to a kind of bit drill.
Background technology
At present, bit drill becomes the multi-functional rock brill of wearing of tooth dig with the rotation of high intensity pick at hydraulic pressure high-frequency percussion brill, hole rising pouring water at the bottom of hole
The rotations such as bucket are dug and are applied relatively broad in the construction of gram rock, and it includes that pick is installed set, pick mounting seat and installs in pick mounting seat
Pick, wherein pick is installed and is overlapped the mode directly welded of employings many with pick mounting seat and be attached, but when pick mounting seat damage
After Huai, needing to employ the tool maintenance such as oxyacetylene metal-cutting, carbon arc air gouging, electric welding machine, substitute mode is relatively complicated, and wastes time and energy.
Utility model content
Technical problem to be solved in the utility model be for above-mentioned prior art exist not enough provide one be easily installed in
The bit drill of dismounting.
The technical scheme that this utility model is used is: a kind of bit drill, installs set, pick mounting seat including pick and is cutting
The pick installed in tooth mounting seat, it is characterised in that: in pick installs set, it is provided with up-small and down-big cubic bellmouth, described section
The upper end of tooth mounting seat is four directions conical head, and described four directions conical head is inserted in the bellmouth of four directions.
By technique scheme, it is provided with cooling water channel at the center of pick mounting seat.
By technique scheme, the upper end installing set at pick is provided with annular boss, for enter rock bar and be connected.
By technique scheme, at pick, set is installed and is circumferentially with contiguous block, the upper surface phase of described contiguous block and pick mounting seat
Coordinate, and by securing member, contiguous block is connected with pick mounting seat.
By technique scheme, the tapering of described four directions conical head is 10 °～18 °.
Acquired by this utility model have the beneficial effect that pick of the present utility model install set and pick mounting seat by four directions taper
Structure is connected, and is not only tightly combined, and does not comes off, and driving torque is big, and installs and dismounting simplicity, is greatly improved
Efficiency of construction and maintenance efficiency.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is decomposing schematic representation of the present utility model.
Fig. 3 is the structural representation that pick of the present utility model installs set.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-3, present embodiments provide a kind of bit drill, including pick install set 1, pick mounting seat 2 and

The upper end of dress seat is up-small and down-big cubic conical head 8, and the tapering of described four directions conical head and four directions bellmouth 7 is 10 °
～18 °, described four directions conical head 8 is inserted in the bellmouth 7 of four directions.Pick of the present utility model installs set 1 and pick is installed
Seat 2 is connected by four directions pyramidal structure, is not only tightly combined, does not comes off, and installs and dismounting simplicity, is greatly improved
Efficiency of construction and maintenance efficiency.This utility model can select the pick mounting seat of different-diameter for the rock stratum of different hardness
(can be such as 280mm-500mm), conveniently to construct.
In the present embodiment, it is provided with cooling water channel at the center of pick mounting seat, for carrying out cold to pick 3 during Chuan Yan
But.
In the present embodiment, the upper end installing set at pick is provided with annular boss 4, for enter rock bar and be connected.
In the present embodiment, at pick, set 1 is installed and is circumferentially with contiguous block 6, described contiguous block 6 and the upper end of pick mounting seat 2
Matching in face, and is connected with pick mounting seat 2 by contiguous block 6 by securing member.Contiguous block 6 installs set with pick for convenience
The welding of 1, the circumferential milling installing set 1 at pick has plane 5, described contiguous block 6 to be welded on the lower end of plane 5.
