Description
Technical field
This utility model relates to mining equipment accessory technical field, is exactly specifically driver multiplex hole head.
Background technology
nullAt present，In expiloration of coal mines or operation，Perforating device has had multiple use，So more and more higher with the requirement of the junction of perforating device to connecting rod，If perforating device applies less moment of torsion with the joint of connecting rod，Transmission capacity may result in too much torque，The coefficient of friction caused is relatively low，And excessive moment of torsion can tensible、Rupture or rupture drilling rod，This is that we are not intended to see，The service life that can cause perforating device and connecting rod shortens，Maintenance cost increases，Perforating device junction of connecting rod and perforating device in operation process there will be projection simultaneously，Resistance is produced in boring procedure，The entrance of perforating device can be affected，And easily cause the abrasion of junction，The dumb convenience of connection is there is based on existing perforating device and connecting rod junction，Bonding strength between perforating device and connecting rod is little，The safety and stablization poor performance of work，The problem that maintenance cost is high and service life is short，Therefore，The connection member of a kind of more reasonably perforating device and connecting rod need to be invented.
Summary of the invention
The purpose of this utility model is to provide driver multiplex hole head, this driver multiplex hole head connects perforating device and connecting rod, it is threaded connection, connected mode is simple, integrated setting, easy installation and removal, realize quick-replaceable, and realize assisting reaming, reduce the abrasion of coupling part, increase the service life.
nullThe technical scheme in the invention for solving the technical problem is: driver multiplex hole head，Including driver body，Described rotation is specially three arc milling steel bodies，It is provided with hard alloy on the cutting face of described driver body，The front end of described driver body is provided with perforating device joint，The rear end of described driver body is provided with connecting rod joint，Described perforating device joint、Connecting rod joint is wholely set with driver body，It is provided with external screw thread on described perforating device joint，It is provided with spacing preiection between described driver body and perforating device joint，Described spacing preiection is that annulus is protruding，When perforating device is connected with perforating device joint，Prevent perforating device from contacting with driver body，Cause damage，Described connecting rod joint is hollow pipe，It is provided with female thread on described connecting rod joint，It is provided with laterally zygomorphic milling plane on described connecting rod joint，Limbers is had inside described driver body and perforating device joint.
As optimization, described rotation three arc milling rigid bodies particularly are uniformly distributed, and angle each other is 120 degree.
As optimization, described connecting rod joint be internally provided with female thread stop surface.
As optimization, described driver surface is coated with wearproof structural tier.
As optimization, described milling plane is provided with frosted layer.
The beneficial effects of the utility model are: compared with prior art; driver of the present utility model multiplex hole head; this driver multiplex hole head connects perforating device and connecting rod; the most all it is threaded connection; connected mode is simple; and integrated setting; easy installation and removal; realizing quick-replaceable, be particularly provided with the Cutting Steel body of arc in rotation, is holed by perforating device in front end; rear end assists reaming by driver body; reduce the abrasion of outer bound pair coupling part, increase the service life, be effectively formed the protection between hole multiplex to driver head and perforating device and connecting rod.
