Abstract
A kind of Multifunctional tool bit tooth, it includes a column connector and the work cephalic par that front end connects, the work cephalic par is a disc, it is equipped with the circular groove of multiple indents on the periphery of the disc, is embedded on the upper outside face between circular groove two-by-two and firm welding there are hard alloy blocks；The lower, transverse of the column connector is provided with pilot hole；The disc half circle face is taper surface, the upper half circle face is a upper conical face, it is allowed to the intermediate cone angle circle for forming an evagination, circular groove made of being connected by bottom semi-circular recesses and outer square groove of multiple indents is equipped on cone angle circle, the hard alloy blocks are embedded and firm welding is on the upper conical face between circular groove two-by-two；It has simple in structure, and easy to use and reliable, intensity is big, and wearability is strong, and service life is long, the features such as capable of improving engineer operation progress.
Description
Technical field
The utility model relates to a kind of Multifunctional tool bit teeth, are mainly used for development machine, milling machine and ditcher etc.
Cutter head tooth belongs to engineering machinery cutter head technical field.
Background technology
Existing engineering machinery cutter head, such as development machine, milling machine and ditcher are equipped with consumables cutter head tooth, often
The cutter head odontoid of rule is in cone-shaped, is arranged or is embedded antifriction metal (AFM) on cone-shaped cephalic par, the lower end on cone-shaped head
Face is connected to cylindricality connector；But this conventional cutter head toothing has a single function, and intensity is low, and service life is short, needs often
It replaces, reduces service efficiency.
Invention content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of simple in structure, user
It can lean on, intensity is big, and service life is long, can improve the Multifunctional tool bit tooth of engineer operation progress.
The purpose of this utility model is completed by following technical solution, a kind of Multifunctional tool bit tooth, it includes one
The work cephalic par that column connector and front end connect, the work cephalic par is a disc, in the disc
Periphery is equipped with the circular groove of multiple indents, is embedded on the upper outside face between circular groove two-by-two and welds jail
Intrinsic hard alloy blocks；The lower, transverse of the column connector is provided with pilot hole.
As preferred：The disc half circle face is that taper surface, the upper half circle face are on one
Taper surface is allowed to the intermediate cone angle circle for forming an evagination, the recessed by bottom semicircle of multiple indents is equipped on cone angle circle
Circular groove made of slot and outer square groove connect, the hard alloy blocks are embedded and firm welding is arc-shaped two-by-two
On upper conical face between groove；
As preferred：The column connector by with the connecting-rod body that is made into integration of work cephalic par and be made into integration
, outer diameter be more than connecting-rod body connection end form, the pilot hole setting connection end on；The connecting-rod body with
The junction of work cephalic par is provided with reinforcement clamping ring.
The utility model have it is simple in structure, easy to use and reliable, intensity is big, and wearability is strong, and service life is long, Neng Gouti
The features such as high engineering job scheduling.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
The A direction views of Fig. 2 Fig. 1.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing：Fig. 1, shown in 2, one kind described in the utility model
