Abstract
The invention discloses a kind of excavator drill bit, it includes drill body, shown drill body has more sub- drill bits, it is provided with the perisporium at the top of the sub- drill bit and digs sword section, the bottom of the sub- drill bit sets promising coniform spiral section, and digging sword section has the multiple digging swords being radially arranged along sub- drill bit.The present invention can not only carry out dry digging, can also carry out wet excavation, can increase the intensity of drill bit, extend its service life.
Description
Technical field
The present invention relates to a kind of excavator drill bit.
Background technology
At present, excavator drill bit is progress mining, tunnel piercing, highway is repaired, armored concrete is broken, broken
The main construction tool of the operations such as frozen soil, it will usually dry digging and wet excavation alternately operating are run into, because its working environment badly needs
Huge abrasion is born, and existing excavator drill bit is often designed as to ensure the life-span of operation in the presence of a harsh environment
Single screw cylindrical, due to can constantly be sheared in use, the active force such as twisting resistance, normal drill bit is in this friendship
Fatigue failure will soon be produced in the presence of varying stress or even is broken, the life-span is very short, and single screw cylindrical bit operation
Efficiency is very low.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided a kind of excavator drill bit, it is not
Dry digging can be only carried out, wet excavation can also be carried out, the intensity of drill bit can be increased, extend its service life.
The present invention solves above-mentioned technical problem and adopted the technical scheme that：A kind of excavator drill bit, it includes drill body,
Shown drill body has more sub- drill bits, is provided with the perisporium at the top of the sub- drill bit and digs sword section, the sub- drill bit
Bottom sets promising coniform spiral section, and digging sword section has the multiple digging swords being radially arranged along sub- drill bit.
A kind of drill body of concrete structure is further provided, the drill body also has general assembly connecting shaft and excavation
Machine drill head upper connecting rod, more sub- drill bits are arranged on excavator drill bit upper connecting rod, and excavator drill bit upper connecting rod is arranged on
In general assembly connecting shaft.
Further provide a kind of concrete structure of excavator drill bit upper connecting rod, described excavator drill bit upper connecting rod
Including excavator drill bit upper connecting rod main shaft and multiple connecting shafts, connecting shaft and sub- drill bit correspond, the sub- drill bit connection
In corresponding connecting shaft.
Further, the multiple sub- drill bit is distributed on using the axis centre of drill body as on the circumference in the center of circle.
Further, described sub- drill bit has six.
After employing above-mentioned technical proposal, sub- drill bit includes spiral section and digs sword section, and wherein spiral section can be carried out doing digging and made
Industry, dig sword section and wet excavation operation carried out in the case of mud off for rotary bit, change single screw cylindrical structure in the past,
Drill bit intensity can be increased, extend its service life.
Brief description of the drawings
Fig. 1 is the general assembly structural representation of the excavator drill bit of the present invention；
Fig. 2 is the front view of the excavator drill bit upper connecting rod of the present invention；
Fig. 3 is the schematic perspective view of the sub- drill bit of the present invention.
Embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail.
As shown in Figures 1 to 3, a kind of excavator drill bit, it includes drill body, and shown drill body has more sub- drill bits
3, it is provided with the perisporium at the top of the sub- drill bit 3 and digs sword section 7, the bottom of the sub- drill bit 3 sets promising coniform spiral shell
Section 6 is revolved, digging sword section 7 has the multiple digging swords being radially arranged along sub- drill bit 3.
As shown in Figures 1 to 3, drill body also has general assembly connecting shaft 1 and excavator drill bit upper connecting rod 2, and more height bore
First 3 are arranged on excavator drill bit upper connecting rod 2, and excavator drill bit upper connecting rod 2 is arranged in general assembly connecting shaft 1.
As shown in Figures 1 to 3, excavator drill bit upper connecting rod 2 includes excavator drill bit upper connecting rod main shaft 4 and multiple connections
Axle 5, connecting shaft 5 and sub- drill bit 3 are corresponded, and the sub- drill bit 3 is connected in corresponding connecting shaft 5.
As shown in Figures 1 to 3, more sub- drill bits 3 are distributed on using the axis centre of drill body as on the circumference in the center of circle.
Sub- drill bit 3 has six, but not limited to this, and six sub- drill bits 3 cause excavator operation efficiency to improve more than 6 times.
The present invention is connected by general assembly connecting shaft 1 with the Hydraulic Power Transmission System of excavator realizes that operation is bored in milling.
The operation principle of the present invention is as follows：
Sub- drill bit includes spiral section 6 and digs sword section 7, and wherein spiral section 6 can carry out dry digging operation, digs sword section 7 and is used to turn round
Drill bit carries out wet excavation operation in the case of mud off, changes single screw cylindrical structure in the past, can increase drill bit intensity, prolong
Its long service life.
Particular embodiments described above, pair present invention solves the technical problem that, technical scheme and beneficial effect carry out
It is further described, should be understood that the specific embodiment that the foregoing is only the present invention, is not limited to this
Invention, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., should be included in this hair
Within bright protection domain.
