Abstract
The invention discloses a drilling bit of an excavator. The drilling bit comprises a bit body. The bit body is provided with a plurality of sub-bits. The peripheral wall of the top of each sub-bit is provided with a cutting edge segment. The bottom of each sub-bit is provided with a conical spiral segment. The cutting edge segment is provided with a plurality of cutting edges arranged radially along the corresponding sub-bit. The drilling bit is available for both dry excavating and wet excavating, strength of the drilling bit can be improved, and service life of the drilling bit can be prolonged.
Description
Technical field
The present invention relates to a kind of excavator drill bit.
Background technology
At present, excavator drill bit carries out mining, tunnel piercing, speedway is repaired, steel concrete is broken, the main construction tool of the operations such as broken frozen soil, usually dry digging and wet excavation alternately operating can be run into, because its work under bad environment needs to bear huge wearing and tearing, and existing excavator drill bit is in order to ensure the life-span of operation in the presence of a harsh environment, often all be designed to single screw cylindrical, owing in use can constantly be sheared, the active forces such as twisting resistance, normal drill bit will soon produce fatigue failure and even rupture under the effect of this alternating stresses, life-span is very short, and single screw cylindrical bit operation efficiency is very low.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of excavator drill bit, and it can not only carry out dry digging, and also can carry out wet excavation, can increase the intensity of drill bit, extend its application life.
The present invention solves the problems of the technologies described above the technical scheme taked: a kind of excavator drill bit, it comprises drill body, shown drill body has multiple sub-drill bit, the perisporium at the top of described sub-drill bit is provided with and digs sword section, the bottom of described sub-drill bit arranges promising cone shape spiral section, dig sword section have arrange along sub-drill bit radial direction multiplely dig sword.
Further provide a kind of drill body of concrete structure, described drill body also has general assembly connecting axle and excavator drill bit upper connecting rod, and multiple sub-drill bit is arranged on excavator drill bit upper connecting rod, and excavator drill bit upper connecting rod is arranged on general assembly connecting axle.
Further provide a kind of concrete structure of excavator drill bit upper connecting rod, described excavator drill bit upper connecting rod comprises excavator drill bit upper connecting rod main shaft and multiple connecting axle, connecting axle and sub-drill bit one_to_one corresponding, described sub-drill bit is connected on corresponding connecting axle.
Further, described multiple sub-drill bit be distributed on the axis centre of drill body for the center of circle circumferentially.
Further, described sub-drill bit has six.
After have employed technique scheme, sub-drill bit comprises spiral section and dig sword section, and wherein spiral section can carry out dryly digging operation, dig sword section and carry out wet excavation operation for rotary bit when mud off, change single screw cylindrical structure in the past, drill bit intensity can be increased, extend its application life.
