Abstract
The utility model discloses the revolving cutting bit of a kind of rig, comprise: cutting assembly and drilling pipe, described drilling pipe is provided with the inner chamber for holding described cutting assembly, it is characterized in that: described cutting assembly comprises cutter and cutter bar, the free end of described cutter stretches out described drilling pipe, described cutter comprise driving shaft and some small-bore drill bits, described cutter bar is respectively at described driving shaft and the detachable connection of described small-bore drill bit, described driving shaft and described drilling pipe coaxial, described small-bore drill bit is coniform distribution around described driving shaft, the head copolymerization of described small-bore drill bit on the axis of described driving shaft place a bit.The technical program can increase the contact area of cutting bit and the scope of operation, and effectively can reduce the loss of power.
Description
Technical field
The utility model relates to bit technique field, especially relates to the revolving cutting bit of a kind of rig.
Background technology
In exploitation or drilling operation, frequent produced problem is exactly fitchering thus causes damage or the broken drill of rig, when relating in particular to complicated mining operations, the different degree of depth has different hardness, and the mechanical stress change of drill bit can cause fractureing or damaging of drill bit too greatly too.And when mining of large scale operation, existing drill bit is often larger, thus drive drill bit so to need to expend very large power, production efficiency is not very desirable.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes the revolving cutting bit of a kind of rig.
The purpose of this utility model will be achieved by the following technical programs: the revolving cutting bit of a kind of rig, comprise: cutting assembly and drilling pipe, described drilling pipe is provided with the inner chamber for holding described cutting assembly, described cutting assembly comprises cutter and cutter bar, the free end of described cutter stretches out described drilling pipe, described cutter comprise driving shaft and some small-bore drill bits, described cutter bar is respectively at described driving shaft and the detachable connection of described small-bore drill bit, described driving shaft and described drilling pipe coaxial, described small-bore drill bit is coniform distribution around described driving shaft, the head copolymerization of described small-bore drill bit on the axis of described driving shaft place a bit.
Preferably, the above-mentioned revolving cutting bit of a kind of rig: described cutting bit also comprises drive motors, and described cutter bar is connected with described drive motors.
Preferably, the above-mentioned revolving cutting bit of a kind of rig: the surface of described cutter bar is helical form, and the end of described cutter bar is plugged on described drive motors.
Preferably, the above-mentioned revolving cutting bit of a kind of rig: the free end of described driving shaft is for conical.
Preferably, the above-mentioned revolving cutting bit of a kind of rig: the head copolymerization of described small-bore drill bit on described driving shaft, and forms pyramidal structure with the free end of described driving shaft.
Outstanding effect of the present utility model is: 1) small-bore drill bit is connected with cutter bar is detachable, according to the quantity of the small-bore drill bit of size adjustment of boring, can remove the trouble of more bit change from; 2) small-bore drill bit is detachable, when small-bore drill bit has damage time, and can more bit change at any time; 3) main shaft and small-bore drill bit with the use of, rotary drilling-head can be made when operation, diminish with the contact area of work layer, only need less power just can drive operation, save power raw material.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of rotary drilling-head of the present embodiment.
Detailed description of the invention
As shown in Figure 1, the revolving cutting bit of a kind of rig of the present embodiment, comprising: cutting assembly and drilling pipe 1, and drilling pipe 1 is provided with the inner chamber 2 for holding cutting assembly, and cutting assembly comprises cutter and cutter bar 3, and the surface of cutter bar is helical form.The free end of cutter stretches out drilling pipe 1, and cutter comprise driving shaft 4 and some small-bore drill bits 5, and the free end of driving shaft 4 is conical design.Cutter bar 3 is respectively at driving shaft 4 and the detachable connection of small-bore drill bit 5, driving shaft 4 is coaxial with drilling pipe 1, small-bore drill bit 5 is coniform distribution around driving shaft 4, the head copolymerization of small-bore drill bit 5 on the axis of driving shaft 4 place a bit, concrete, the head copolymerization of small-bore drill bit 5 on driving shaft 4, and forms pyramidal structure with the free end of driving shaft 4.
The cutting bit of the present embodiment also comprises drive motors 6, drive motors 6 is the powered rotation of drill bit, and one end of cutter bar 3 is connected with drive motors 6, by the rotation of drive motors 6, drive cutter bar 3 along with rotation, thus drive driving shaft 4 and small-bore drill bit 5 rotary operation.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
