Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
The drill bit assembly of the pressure drilling machine for the mine as shown in the figure comprises a top ring 1 and an inner pipe body 2 which are connected through a support plate 6 and a scraper 4. The supporting plate 6 connects the top ring 1 with the middle section of the inner pipe body 2, and the top ring and the inner pipe body are arranged in the horizontal direction to play a role in power supporting. The scraper 4 connects the top ring 1 with the bottom section of the inner pipe body 2 and is arranged in an inclined direction, so that spiral drilling is facilitated.
A plurality of inclined casing pipes 3 are uniformly arranged on the scraper 4, and an I-shaped drill bit 8 is arranged in the scraper. A plurality of vertical sleeves 3 are circumferentially arranged at the bottom of the inner pipe body 2, and II-shaped drill bits 9 are arranged inside the vertical sleeves. In the use process of the drilling press, the drill rod drives the drill bit assembly to rotate downwards to advance. Therefore, the drill bit on the side of the inner pipe body 2 needs stronger wall breaking capability, and the drill bit on the lower side needs stronger impact capability. In this embodiment, the I-shaped drill 8 is provided with a sharp head to facilitate the downward slant excavation. The II-type drill bit 9 is provided with a blunt head, and the head is provided with a bulge which concentrates the compression force and is convenient for crushing underground rocks; a plurality of reinforcing ribs are circumferentially distributed on the side part to inhibit the body from deforming.
A plurality of inclined casing pipes 3 are arranged circumferentially below the top ring 1, and I-shaped drill bits 8 are arranged in the inclined casing pipes. After the drill bit assembly excavates certain degree of depth, top ring 1 can with loam layer direct contact, I type drill bit 8 can break the loam layer fast this moment.
The top of the inner pipe body 2 is provided with a flange 5, which is convenient for connecting a drill rod. The inner pipe body 2 is also provided with a window 7 along the length direction for overflowing sand and stones inside. Along with the continuous decline of interior body 2, can deposit a large amount of earth in it, intraductal earth forms impact resistance to outside of tubes earth, is not convenient for broken. After the window 7 is arranged, soil is timely removed along with excavation, and the inner pipe body 2 can always keep constant excavation speed.
The drill bit assembly is integrally conical, the pointed drill bit is spirally arranged on the drill bit assembly, and the blunt drill bit is vertically arranged at the bottom of the drill bit assembly, so that the excavating efficiency is improved.
The above are specific embodiments of the present invention, but the scope of protection of the present invention should not be limited thereto. Any changes or substitutions which can be easily conceived by those skilled in the art within the technical scope of the present invention are covered by the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the claims.
