Description
Technical Field
The invention belongs to the field of drilling machines, and particularly relates to a drill bit for a drilling machine.
Background
Foundation engineering is a main object of research in the building industry, and construction difficulty is different due to different rock stratum structures in various places. The cast-in-situ bored pile is the most conventional and common construction technology for foundation construction, and a rotary drill bit is usually adopted as a hole forming device. However, when strong cohesive soil is encountered, the muck is often easily stuck in the drill cylinder and is difficult to unload, and at the moment, manual assistance is often needed to scrape the slag, so that the processing efficiency is greatly reduced, the pore-forming time is prolonged, the hidden danger of hole collapse is increased, and the requirements of engineering cannot be met. In order to solve one problem, technicians arrange a push plate and an elastic push rod in the drill barrel so as to assist in pushing out the muck. But because the push rod has elasticity, can form bulldozing to the dregs in the brill bucket in drilling process, make the dregs more closely knit, be difficult to push out. In addition, the push rod is only arranged on one side, so that the push plate is stressed unevenly and is easy to clamp in the drilling barrel.
Disclosure of Invention
The invention aims to provide a drill bit for an excavating and drilling machine, wherein a push plate of the drill bit for the excavating and drilling machine is uniformly stressed, and the pushing of dregs is more labor-saving.
In order to achieve the technical effects, the invention adopts the following technical scheme:
the utility model provides a dig drill bit for rig, includes drill bit base and bores a section of thick bamboo, bore a section of thick bamboo lower extreme through latched device with drill bit base links to each other, bores a section of thick bamboo upper end and is equipped with the drilling rod interface and is used for triggering latched device's locking lever, bores a section of thick bamboo inner wall and evenly is equipped with three protruding guide rail, digs drill bit for rig still including unloading the sediment push pedal and unloading the sediment push rod, it is located to unload the sediment push pedal in the bore a section of thick bamboo, have with protruding guide rail complex spill breach, unload the sediment push pedal along protruding guide rail up-and-down motion, unload the sediment push rod and wear to locate movably drill bit upper end.
In order to make the dregs easily enter the drill barrel, at least one exhaust hole is arranged on the dregs discharging push plate, so that the air resistance is reduced.
Furthermore, three circular limiting parts are arranged on the slag discharging push plate, and the limiting parts correspond to the slag discharging push rods in position and are used for limiting the sliding dislocation of the slag discharging push rods, so that the slag discharging push plate is stressed unevenly; the slag discharging push plate is also provided with an avoiding notch for the lock rod to pass through.
In order to make the drill bit simple in structure and convenient to maintain, the slag discharging push rod is of a full-thread structure and is in threaded connection with the upper end of the drill barrel and can be screwed in and out up and down.
Furthermore, in order to prevent the slag discharging push plate from falling off from the bottom, the protruding guide rail is L-shaped or inverted T-shaped.
As a further improvement of the technical scheme, one end of the drill base is hinged with the drill cylinder, and the other end of the drill base is in lap joint with the locking block on the locking rod through the locking hook on the drill base.
During operation, unload the sediment push rod and be located the top, break away from with unloading the sediment push pedal, unload the sediment push pedal and move up along protruding guide rail under the effect of dregs, when removing the top, take out the drill bit, trigger latched device with the locking lever, open the drill bit base, the rotatory sediment push rod of unloading makes and unloads the spacing portion that the sediment push pedal withstood to unload the sediment push rod, pushes away dregs downwards. When the slag discharging push plate reaches the lower end of the raised guide rail, the slag is clamped by the L-shaped or inverted T-shaped structure, and the pushing of the slag soil is finished.
The invention has the beneficial effects that: (1) the invention has simple structure, low cost and easy popularization and use.
(2) The drill bit for the drilling machine has the advantages that the slag soil is not pressed and is not compact, and the slag pushing is labor-saving.
(3) According to the drill bit for the drilling machine, the protruding guide rail can limit the slag discharging push plate to prevent deviation, and the slag discharging push plate is uniformly stressed, so that the drill bit is not easy to clamp and has few faults.
