Background
In the prior art, in the process of carrying out pile foundation construction of a rock-soil layer, drilling equipment or a pneumatic down-the-hole hammer in a rotary cutting tunneling mode is mostly adopted for pile driving construction of the rock-soil layer, but under the condition of high load, the output torque and the drilling pressure of the rotary cutting type drilling equipment have high requirements on the configuration of the whole machine, the cost of the drilling equipment is high, and the damage rate of a drill bit and a main machine is also high.
The drill bit is an indispensable part in common engineering construction equipment, and the structural characteristics of the drill bit directly determine the height of the construction efficiency. The existing rock-entering drill bit has the defects of low construction efficiency, low footage speed and the like.
CN 205025365U discloses an alloy-inlaid drill bit for rock entering, which is an integrated milling and forming structure and is a two-stage step structure; the first step is a drill bit fixing seat and is used for supporting the whole drill bit structure, and the second step is a drill bit main body and is used for completing cutting in the construction process; and the rock-entering alloy-embedded drill bits are assembled and fixed through the positioning blocks to form a combined drill bit for crushing. The structure is in a combined step shape, and is suitable for the working environment of the rock-entering piling drilling machine; the appearance cross-section of this structure is fan-shaped, and this fan-shaped structure makes when the drill bit strikes breakage and rotary cutting, and the circumferential line speed is impartial, broken rock that can be even, and crushing effect is good, provides very good prerequisite for the getting rid of follow-up disintegrating slag. Inlay the alloy on the sector of drill bit main part, also inlay the alloy simultaneously on the excessive arc curved surface of drill bit fixing base and drill bit main part junction, the alloy on the arc curved surface also can be broken like this or roll the detritus stone, reaches fine crushing effect.
Disclosure of Invention
The utility model discloses carry out configuration optimization on the basis of CN 205025365U patent, provide an energy exchange, simple structure, crushing effect are good, the construction footage is fast, the integral drill bit of income rock that work efficiency is high. The utility model discloses the work efficiency of pile driver aircraft nose can effectively be promoted to this time application utility model drill bit.
In order to achieve the above object, the utility model discloses a technical scheme be an go into integral drill bit of rock, its characterized in that: the bottom of the drill bit parent body is a drill bit working plane, the working plane is in a fan shape, and convex alloy is distributed on the working plane; the top of drill bit matrix is installed the direction fixed cylinder, and the direction fixed cylinder plays flexible guide effect to the drill bit matrix, and the side of the fixed cylinder of direction simultaneously mills has the semicircle slot hole, inserts circular pin in the semicircle slot hole and will go into the integral drill bit of rock and be connected with fixed matrix, does not fall out fixed matrix when making the integral drill bit of rock out of work.
The guide fixing cylinder transmits impact force to a working plane at the bottom of the drill bit matrix and plays a role in guiding when the rock-entering integral drill bit slides in a telescopic mode.
Several groups of rock-entering integral drill bits are uniformly distributed on the outer side of the circumference for revolution;
further, the impact force directly acts on the matrix of the drill bit, and an intermediate transition link is omitted, so that energy loss is reduced.
Further, the shape of the work plane can also be rectangular, square, etc.
Further, the rock-entering integral drill bit is horizontally positioned through the positioning block and the fixed matrix, so that the shearing resistance of the rock-entering integral drill bit is improved.
Compared with the prior art, the utility model discloses following beneficial effect has.
1. The structure is an integral structure, the drill bit and the impact force transmission structure are integrated, so that the impact force is directly applied to the working plane of the drill bit, no intermediate transition link exists, no intermediate loss exists in energy, and the impact force applied to the unit area of the working plane of the drill bit is increased.
2. The mass of the drill bit and the mass of the impactor and the like can enable energy to be transmitted in an equivalent manner, and impact energy absorbed by the weight of the drill bit is reduced.
Drawings
FIG. 1 is a side view of a drill bit;
FIG. 2 is a drill bit installation view;
in the figure: 1. the drilling tool comprises a convex alloy, 2, a drill bit matrix, 3, a semicircular long hole, 4, a guide rod, 5, an impactor, 6, a positioning pin and 7 a positioning block.
Detailed Description
As shown in fig. 1, the bottom of a drill bit matrix 2 is a drill bit working plane, the working plane is in a fan shape, and convex alloy 1 is distributed on the working plane; the top of drill bit matrix 2 is installed direction stationary cylinder 4, and direction stationary cylinder 4 plays flexible guide effect to drill bit matrix 2, and the side of the stationary cylinder that leads simultaneously mills semicircle slot hole 3, inserts circular pin in semicircle slot hole 3 and will go into the integral drill bit of rock and be connected with fixed matrix, does not drop out fixed matrix when making the integral drill bit of rock inoperative.
The guide fixing cylinder 4 transmits impact force to a working plane at the bottom of the drill bit matrix 2, and plays a role in guiding when the rock-entering integral drill bit slides in a telescopic mode.
Fig. 2 is a drill mounting diagram, and the impactor 5 applies impact force to the guide fixing cylinder 4 and directly acts on the drill parent body 2; the positioning pin 6 is used for clamping the guide fixing cylinder 4, the positioning block 7 is arranged at the bottom of the fixing matrix, and the positioning block 7 is used for realizing horizontal positioning and increasing the shearing resistance of the rock integrated drill bit. The utility model discloses a structure directly transmits the impact force of jump bit to work plane's alloy on, reduces the middle link that consumes, makes the impact force grow on every alloy, and the effort on the single face area is the biggest, increases the efficiency of broken rock, and then provides the efficiency of construction.
