The dry pore-forming slag-removing drill bit is characterized in that: the included angle between the blade and the central axis of the drill bit is 60-75 degrees, the cover plate is connected with the opening of the drill bit by a hinge, the cover plate rotates to have two limit positions, and the included angles between the cover plate and the central axis of the drill bit are 45 degrees and 90 degrees respectively when the cover plate rotates to have two limit positions.
The use method of the dry pore-forming slag-removing drill bit is characterized in that: the method is implemented in sequence according to the following steps:
① pushing earth, starting the drilling machine, the drilling machine drives the drill body and the drill bit to rotate synchronously, the blade rotates to dig earth, the drill bit is pushed downwards synchronously when rotating, the cover plate is opened upwards under the pushing action of the soil layer, and the residue earth scraped by the blade enters the inner cavity of the drill bit through the cover plate;
② and stopping the drilling machine, lifting the drill bit upwards, closing the cover plate downwards under the action of self gravity and the gravity of the slag in the inner cavity of the drill bit, closing the inner cavity of the drill bit, and moving the drill bit to other places to clean the slag in the inner cavity.
The invention is all mechanical construction, firstly, the cover plate is opened to 45 degrees by utilizing the pressure of the dregs generated by the rotary excavation of the drilling machine, and when the drilling machine stops upwards withdrawing, the cover plate is automatically closed due to the self weight and the pressure of the dregs in the barrel, thereby avoiding the dregs in the drill bit from leaking downwards, fully realizing the safe and civilized construction and establishing the aim of a conservation-oriented society.
The invention has the following beneficial effects:
1. the device is simple, the manufacture is convenient, and the equipment cost is low;
2. construction is convenient, operation efficiency is improved, and construction cost is reduced.
