Abstract

The utility model discloses a square drill bit of a rotating drill. The square drill bit comprises a square head assembly (1), guide body assemblies (2), a drill bit main body (3), screws (4) and abrasion resistant blades (5). The square head assembly is welded at the midpoint of the upper end surface of the drill bit main body, the guide body assemblies are respectively welded at the upper ends of four side surfaces of the drill bit main body, and the abrasion resistant blades are respectively fixedly arranged at the lower ends of the four side surfaces through the screws. The square drill bit solves the problem of square pile hole wall repairing forming of rotating drill users in projects of square pile holes in shallow soil layers, reduces cost, and is simple in structure and easy to process.

Description

The square drill bit of rotary drilling rig
Technical field
The utility model relates to the square drill bit of a kind of rotary drilling rig.
Background technology
Rotary drilling rig is a kind of stake construction equipment for the pore-forming operation, and it mainly utilizes unit head to drive drilling rod, and by drilling rod the driving force of unit head and plus-pressure is passed to drill bit and realizes the cutting on stratum and creep into.At present, the rotary drilling rig drill bit is circle on the market, be mainly used in the construction in cylinder pile hole, when the rotary drilling rig user runs into the engineering in barrette hole, existing rotary drilling rig drill bit is difficult to satisfy instructions for use, owing to the size reason of equipment, all less than 2 meters barrette hole, can't adopt subterranean continuous wall hydraulic grab to come construction operation for length and width in addition; And two-wheel mills the economy that equipment constructs under soil layer shallow bore hole operating mode lower, and needs the user to increase huge cost to buy two-wheel and mill equipment.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of rotary drilling rig square drill bit, solves the wall shaping problem of repairing in rotary drilling rig user barrette hole in the engineering of the barrette hole of soil layer shallow bore hole, reduces cost, and is simple in structure, is easy to processing.
To achieve these goals, the utility model is achieved through the following technical solutions: the square drill bit of a kind of rotary drilling rig, comprise square toes assembly, guide way assembly, drill main body, screw and wearing blade, the square toes assembly is welded on the centre of the upper surface of drill main body, upper end, four sides at drill main body all is welded with the guide way assembly, and lower end, four sides all is mounted with wearing blade by screw.
The beneficial effects of the utility model are: solved the barrette hole that the rotary drilling rig user can directly adopt the rotary drilling rig to finish the barrette hole engineering of soil layer shallow bore hole and repaiied wall shaping work, simple in structure, be easy to processing, cost of production and maintenance cost are low, under the soil layer operating mode, the drilling efficiency height, good economy performance is especially changed very convenient after the wearing blade wearing and tearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, square toes assembly, 2, the guide way assembly, 3, drill main body, 4, screw, 5, wearing blade.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; the square drill bit of this rotary drilling rig; comprise square toes assembly 1; guide way assembly 2; drill main body 3; screw 4 and wearing blade 5; square toes assembly 1 is welded on the centre of the upper surface of drill main body 3; upper end, four sides at drill main body 3 all is welded with guide way assembly 2; the guide way assembly 2 of welding plays guide effect around the drill main body 3 when carrying brill; prevent that the square drill bit of rotary drilling rig from snapping in the hole wall in barrette hole when upwards promoting; effectively the protection drill main body is not worn simultaneously; prolong the application life of the square drill bit of rotary drilling rig; lower end, four sides all is mounted with wearing blade 5 by screw 4, is convenient to change after wearing blade 5 wearing and tearing.
During work, the deadweight of drilling rod and the plus-pressure of unit head are passed on the wearing blade 5 of the square drill bit of rotary drilling rig, and the stratum that 5 pairs of middle parts of wearing blade have cut into circular hole is cut, thereby the wall of repairing of finishing the barrette hole is shaped.

Claims (1)
