For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Novel diaborit, improves the abrasion resistance of drill bit, extends its application life.
For solving the problem, the technical scheme that the utility model adopts is as follows:
A kind of Novel diaborit, comprise drill body, the center of drill body is provided with first jet, drill body external surface is evenly distributed with 3 wing assemblies, and the top of this wing assembly is provided with multiple second nozzle; Wing assembly comprises arrangement along clockwise direction and extends downward the first wing, the second wing, the 3rd wing of drill body side by drill body top, the length of the first wing, the second wing, the 3rd wing reduces successively, and the bottom of the first wing, the second wing, the 3rd wing is concordant; The external surface of the first wing, the second wing, the 3rd wing is provided with the multiple impregnated post along its length reversed arrangement separately; Drill body external surface is provided with multiple gauge block be connected with the bottom of the first wing, the second wing, the 3rd wing, gauge block is provided with diamond glomerocryst insert; The top of the first wing is provided with cutting teeth.
Preferably, impregnated post comprises the first impregnated post, the second impregnated post and the 3rd impregnated post, and the first impregnated post, the second impregnated post are formed by the outside projection of wing module outer surface, and the first impregnated post height is less than the height of the second impregnated post; 3rd impregnated post is the length direction semicolumn consistent with the width of wing assembly.
Preferably, the external surface of the first wing to be arranged to bottom the first impregnated post, the 3rd impregnated post, the second impregnated post successively by top; The external surface of the second wing, the 3rd wing to be arranged to bottom the first impregnated post, the second impregnated post, the 3rd impregnated post successively by top.
The beneficial effects of the utility model are:
Compared to existing technology, Novel diaborit of the present utility model, adopt the wing assembly that 3 groups are evenly arranged, often organize the wing that length that wing assembly comprises is different, effectively can reduce the adamantine content of bit central, increase shoulder diamond content easy to wear, make impregnated bit have stronger abrasion resistance, extend the application life of impregnated bit, all increase in the drilling depth and drilling speed of drill bit.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
A kind of Novel diaborit as described in Fig. 1,2, comprise drill body 100, the center of this drill body 100 is provided with first jet 140, and on drill body 100 external surface, be evenly distributed with 3 wing assemblies, the top of this wing assembly is provided with multiple second nozzle 115, the landwaste in centre, shaft bottom can be rinsed well by above-mentioned first jet 140, and the second nozzle 115 be provided with then makes the area rinsed increase, and strengthens flushing dynamics.
Concrete above-mentioned wing assembly comprises the first wing 110, second wing 120, the 3rd wing 130, first wing 110, second wing 120, the 3rd wing 130 are arranged along clockwise direction, and are extended downward drill body 100 side by drill body 100 top; In addition, the length of this first wing 110, second wing 120, the 3rd wing 130 reduces successively, but the bottom of the first wing 110, second wing 120, the 3rd wing 130 is concordant; This structure makes the cutting face of drill bit has more multiple blade contact shaft bottom, cutting dynamics can be strengthened, and above-mentioned first wing 110, second wing 120, the 3rd wing 130 all on same horizontal plane, be less likely to occur tilt, improve the stability of drill bit, strengthen practicality.
In addition, multiple impregnated post is provided with at the external surface of the first wing 110, second wing 120, the 3rd wing 130, this impregnated post is along its length reversed arrangement separately, this split type impregnated cutting structure replaces the impregnated cutting structure of original monolithic, is alternately embedded on wing by difform impregnated post, forms the drill bit of split type impregnated cutting structure, the cutter set density of structure can be reduced further, strengthen cutting dynamics, strengthen the efficiency of breaking rock of impregnated bit, increase the service life.
In addition, drill body 100 external surface is provided with multiple gauge block 150 be connected with the bottom of the first wing 110, second wing 120, the 3rd wing 130, this gauge block 150 can effectively avoid drill bit to wear and tear in lasting use procedure, cause bit diameter to diminish, improve the application life of drill bit.And on gauge block 150, being provided with diamond glomerocryst insert, the diamond glomerocryst inlayed effectively raises the anti-wear performance of impregnated bit, can keep keen edge, reaches the object improving bit life.
Certainly, the top of above-mentioned first wing 110 is provided with cutting teeth 111, and different cutting teeths 111 alternately contacts rock stratum, and broken rock moment of torsion is little, and cutting teeth 111 is little with the contact area of rock stratum, and specific pressure is high, is easy to wedging stratum and relatively reduces wear, and improves broken rock speed.
Preferably, impregnated post comprises the first impregnated post 113 of impregnated post 112, second and the 3rd impregnated post 114, the impregnated post 113 of first impregnated post 112, second is all formed by the outwardly protrusion of wing assembly, and the first impregnated post 112 is highly less than the height of the second impregnated post 113; 3rd impregnated post 114 is then semicolumn, and the length direction of the 3rd impregnated post 114 is consistent with the width of wing assembly.Adopt the impregnated post of different structure to be alternately distributed on wing, the abrasion resistance of this device can be improved while the cutting effect improving this drill bit, increase the service life.Certainly, above-mentioned impregnated post also can be set to other shapes as oblate spheroid capitiform, track type, square or wedge.
Further, the first wing 110 upper outer surface to be arranged to bottom the first impregnated post 112, the impregnated post 113 of the 3rd impregnated post 114, second successively by top; The external surface of the second wing 120, the 3rd wing 130 to be arranged to bottom the impregnated post 113 of the first impregnated post 112, second, the 3rd impregnated post 114 successively by top.This rational in infrastructure section changing drill bit, the impregnated post number that the easily-worn position of drill bit is arranged maximizes as far as possible, improves the abrasion resistance of drill bit.Be understandable that, the arrangement mode of above-mentioned impregnated post on different wing can have multiple, is not limited only to the permutation and combination provided in the present embodiment.
Wing, compared to original impregnated bit, is widened, is deepened by above-mentioned Novel diaborit, increases the adamantine content of drill bit simultaneously, and the diamond particles adopted is thinner, makes this drill bit more wear-resisting; In addition, adopt split type impregnated cutting structure to replace the impregnated cutting structure of original monolithic, also increase in the drilling depth and drilling speed of drill bit while ensureing abrasion resistance.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
