Abstract
The utility model discloses a pavement milling machine mills planer tool head, the work tooth of being made by carbide adopts the braze joint to form with the steel base member. The work tooth comprises prong and tooth body, and the surface of tooth body is equipped with the recess. The cross section of recess is dish or circular. The surface of tooth body has two recesses that the shape is the same, radial evenly distributed in the surface of tooth body at least. The degree of depth of recess is 0.5~1.5mm. The utility model discloses a change the surface texture that mills planer tool head work tooth, under the condition that does not influence the alloy intensity of milling the planer tool head and life, reduced the weight of remaining of milling the alloy volume and the alloy use amount of planer tool head and milling the planer tool head when scrapping, both practiced thrift the alloy resource, reduced manufacturing cost again.
Description
Technical field
This utility model relates to a kind of pavement milling machine, the milling cutter head of a kind of pavement milling machine.
Background technology
Pavement milling machine is the major mechanical of asphalt pavement conserving construction machinery, for urban road, at a high speed public affairs
Bag, oil wave, reticulate pattern, rut etc. are gathered around in the removing of the asphalt concrete surface layer such as road.Pavement milling machine milling is used to damage
Old laying, re-lay the modernization maintenance process that new surface layer is the urban road of a kind of economy, highway.
Owing to pavement milling machine work efficiency is high, milling depth is easily controllable, flexible to operation, mobility is good,
The old material of milling can directly recycle, thus is widely used in the maintenance project of urban road, highway.
Milling cutter head is the main tool that pavement milling machine carries out road-surface milling construction, and structure is to use hard to close
The work tooth of gold is formed by connecting with steel body soldering.Work tooth is usually designed to bell shape, and its crown undertakes
Cutting task, roomy bottom guarantees and being reliably connected of steel body.During work, for prevention steel body
Abrasion, improve work efficiency, when the work odontotripsis of milling cutter head is to bottom maximum gauge, i.e. should be more
The cutter head renewed.But the work tooth of existing milling cutter head is as shown in Figure 4, Figure 5, full appearance causes cutter head
When scrapping, the resid vol of work tooth is relatively big, causes the waste that hard alloy is unnecessary.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, it is provided that the milling of a kind of pavement milling machine
Planing cutter head.
To achieve these goals, this utility model is by the following technical solutions:
The milling cutter head of a kind of pavement milling machine, the work tooth being made up of hard alloy uses pricker with steel body
Weldering is formed by connecting.Work tooth is made up of crown and tooth body.The surface of tooth body is provided with groove.
This utility model is for the milling cutter head full appearance of existing pavement milling machine, work when causing cutter head to be scrapped
Make the resid vol of tooth relatively big, cause the defect of the unnecessary waste of hard alloy, to existing pavement milling machine
Milling cutter head improve.Recessed in the tooth body surface configuration of the work tooth of existing pavement milling machine milling cutter head
Groove.Do not affecting milling cutter head work tooth hard alloy intensity and in the case of service life, by changing milling
The surface texture of planing cutter head work tooth, the residual weight when usage amount of minimizing hard alloy and milling cutter head are scrapped
Amount, reduces production cost.
Further improve and be: the surface groove that at least two shapes are identical of described tooth body, radially uniform
It is distributed in the surface of tooth body.The radially uniform surface being distributed in tooth body of groove, can make work tooth use
Uniform force in journey.
Further improve and be: the cross section of described groove is dish-shaped or circular.This shape is easy to processing.
Further improve and be: the degree of depth of described groove is 0.5～1.5mm.This depth of groove can ensure that not
Affect intensity and the service life of milling cutter head work tooth hard alloy, save alloy resource and production cost.
Effect of the present utility model is: by changing the surface texture of milling cutter head work tooth, do not affecting
The alloy strength of milling cutter head and in the case of service life, decreases alloy volume and the alloy of milling cutter head
Residual weight when usage amount and milling cutter head are scrapped, had both saved resource, had reduced again production cost.

Detailed description of the invention
Below, in conjunction with the accompanying drawings and embodiments this utility model is further described:
As shown in FIG. 1 to 3, milling cutter head of the present utility model is made up of hard alloy work tooth and steel
Matrix 4 use soldering to be formed by connecting.Work tooth is bell shape, is made up of crown 1 and tooth body 2, tooth body 2
Surface be provided with groove 3.The cross section of groove 3 is dish-shaped or circular, and the degree of depth of groove 3 is 0.5～1.5mm.
In the present embodiment, there is a groove 3 that five shapes are identical on the surface of tooth body 2, radially uniform is distributed in tooth
The surface of body 2, can make work tooth in use uniform force.The cross section of groove 3 is dish, recessed
The degree of depth of groove 3 is 1mm.
Claims (4)
1. a milling cutter head for pavement milling machine, the work tooth being made up of hard alloy and steel body use soldering to be formed by connecting；Work tooth is made up of crown and tooth body, it is characterised in that: the surface of tooth body is provided with groove.
The milling cutter head of a kind of pavement milling machine the most according to claim 1, it is characterised in that: the surface groove that at least two shapes are identical of described tooth body, the radially uniform surface being distributed in tooth body.
