Abstract
The invention provides a high-strength drilling rig. The high-strength drilling rig comprises a hollow drill pipe, a drill bit and knives, wherein a connecting ring is arranged between the upper portion of the drill bit and the drill pipe; a soil breaking knife is arranged on the connecting ring; and the knives are arranged on the bottom of the drill bit. The sizes of the knives are different, and the knives are arrayed irregularly. The soil breaking knife is triangular, a reinforcing block is arranged between the drill bit and the connecting ring, the drill bit and the connecting ring cannot be broken easily, the strength of a whole structure is guaranteed, and the service life of the high-strength drilling rig is long. The drill bit is not easy to block, the drill pipe is pulled out easily, and the overall strength of the drilling rig is high.
Description
Technical field
The invention relates to a kind of tapping equipment, particularly relates to a kind of high strength drilling tool.
Background technology
When bore operation, a large amount of earth is gathered in drill bit position, easily results in blockage to the work of drill bit, when drilling depth reaches, need to extract drilling rod, usually due to the accumulation of earth, extracting of drilling rod can be very difficult, and boring inefficiency, drilling rod also easily damages.
Summary of the invention
The problem that the invention will solve is to provide a kind of high strength drilling tool, has higher intensity, not easily blocks, and drilling rod is extracted easily simultaneously.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of high strength drilling tool, comprises the drilling rod of hollow, drill bit, cutter, the connecting ring arranged between drill bit top and drilling rod, the hack cutter that connecting ring is arranged, described cutter is arranged on bottom drill bit.
Further, described cutter is different size and irregular alignment.
Further, described drill bit is provided with two vertical row chip-removal holes, the chip-removal hole largest diameter of bit central position.
Further, hack cutter is the triangular structure of band radian.
Further, described connecting ring upper surface has annular groove.
Further, boss is provided with between described drill bit and connecting ring.
The advantage that the invention has and good effect are: have chip-removal hole, drill bit not easily blocks, and drilling rod is extracted easily simultaneously, and entire drill tool intensity is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention;
Fig. 2 is the structural representation of the invention connecting ring;
Fig. 3 is the structural representation of the invention hack cutter.
In figure: 1-drilling rod; 2-drill bit; 3-cutter; 4-connecting ring; 5-hack cutter; 6-boss; 7-chip-removal hole; 41-annular groove.
Detailed description of the invention
A kind of high strength drilling tool, comprises the drilling rod 1 of hollow, drill bit 2, cutter 3, the connecting ring 4 arranged between drill bit 2 top and drilling rod 1, and the hack cutter 5 that connecting ring 4 is arranged, described cutter 3 is arranged on bottom drill bit 2.
Described cutter 3 is different size and irregular alignment, and described drill bit 2 is provided with two vertical row chip-removal holes 7, and chip-removal hole 7 largest diameter of drill bit 2 center, does not affect overall drilling efficiency when part tool wear, and boring is more efficient, and casting is smooth and easy.Hack cutter 5 is the triangular structure of band radian, and drilling rod moves forward and backward and all can not be stuck, and drilling rod is extracted easier.Described connecting ring 4 upper surface has annular groove 41, and drilling rod inserts welding in annular groove 41, and bit damage only need cut away welded junction part.Be provided with boss 6 between described drill bit 2 and connecting ring 4, drill bit 2 and connecting ring 4 can not be twisted off easily, and ensure overall construction intensity, the life-span is longer.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
