Description
Technical field
The utility model relates to cutter accessory field, particularly relates to a kind of shield machine cutter.
Background technology
Shield machine is mainly used in the construction field of the engineerings such as city underground, railway, highway, tunnel; shield machine is mainly pushed ahead along canal axes by a cylindrical shield machine main body; soil is excavated simultaneously; the housing of shield machine main body carries out temporary support to also not serving as a contrast the tunnel cut for the protection of shield machine internal part simultaneously, prevents soil layer around from caving in.Shield machine commonly uses excavating tools as one, and the cutter of shield machine, as the core component of shield machine, has a very important role.At present, common shield machine cutter is due to design feature and use frequent, and wearing and tearing are very fast, and application life is short, usually need to change, and improve construction cost, also have impact on efficiency of construction simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of shield machine cutter, and overcome traditional shield machine cutter abrasion fast, application life is short, removes and installs the defect of inconvenience.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of shield machine cutter, comprise handle of a knife, cutter head, revolution switch, described cutter head is arranged on the side of described handle of a knife upper end, the top end surface of described handle of a knife is installed with wear-resistant block, the front end of described cutter head is provided with groove, the periphery of described cutter head is provided with wearing layer, in described groove, cutting blade is installed, described revolution switch is located on described handle of a knife, described cutter head inside is also provided with permanent magnet, described permanent magnet is connected with described revolution switch, described revolution switch is for driving described permanent magnet clockwise or rotate counterclockwise 90 °, the two ends of described groove are fixed with soft magnetic materials, contact with described soft magnetic materials in described permanent magnet rotating process.
The beneficial effects of the utility model are: structure is simple, it is quick and convenient to remove and install, and improves the anti-wear performance of cutter, extends application life.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described wear-resistant block is fixed by welding on the top end surface of described handle of a knife.
The beneficial effect of above-mentioned further scheme is adopted to be: to be fixed by welding manner, solid and reliable, difficult drop-off.
Further, described wear-resistant block is that carbide alloy is made.
The beneficial effect of above-mentioned further scheme is adopted to be: abrasion resistance is strong, extends application life, reduces financial cost.
Further, the quantity of described wear-resistant block is six, and six described wear-resistant blocks are evenly arranged into two row.
Adopt the beneficial effect of above-mentioned further scheme to be: to be uniformly distributed, wear-resistant block is adequately protected handle of a knife, avoids handle of a knife to be worn.
Further, described wearing layer is welded on the periphery of described handle of a knife by built-up welding.
The beneficial effect of above-mentioned further scheme is adopted to be: to take built-up welding mode to weld, simple to operate, cost is low, extends application life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of shield machine cutter of the utility model.
In accompanying drawing, the list of parts representated by each label is as follows:
1, handle of a knife, 2, revolution switch, 3, wear-resistant block, 4, wearing layer, 5, cutting blade, 6, groove, 7, cutter head.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of shield machine cutter of the utility model, comprise handle of a knife 1, cutter head 7, revolution switch 2, described cutter head 7 is arranged on the side of described handle of a knife 1 upper end, and the top end surface of described handle of a knife 1 is installed with wear-resistant block 3.The quantity of described wear-resistant block 3 is six, and six described wear-resistant blocks 3 are evenly arranged into two row, and described wear-resistant block 3 is made for Hardmetal materials, and described wear-resistant block 3 is fixed by welding on the top end surface of described handle of a knife 1.The front end of described cutter head 7 is provided with groove 6, and the periphery of described cutter head 7 is provided with wearing layer 4, and described wearing layer 4 is welded on the periphery of described handle of a knife 1 by built-up welding.In described groove 6, cutting blade 5 is installed, described revolution switch 2 is located on described handle of a knife 1, described cutter head 7 inside is also provided with permanent magnet, described permanent magnet is connected with described revolution switch 2, described revolution switch 2 is for driving described permanent magnet clockwise or rotate counterclockwise 90 °, and revolution switch 2 turns clockwise after driving permanent magnet to turn clockwise just permanent magnet can only to be rotated counterclockwise after 90 ° 90 ° to reset again.The two ends of described groove 6 are fixed with soft magnetic materials, contact in described permanent magnet rotating process with described soft magnetic materials.Permanent magnet is when initial position, vertical with groove 6, and when after permanent magnet rotating 90 °, the two ends of permanent magnet contact with the soft magnetic materials on groove 6, produce powerful attraction, make cutting blade 5 be adsorbed on permanent magnet, difficult drop-off.
Its course of work is: first drive permanent magnet to rotate by revolution switch 2; the two ends of permanent magnet are contacted with the soft magnetic materials on groove 6; produce powerful attraction; cutting blade 5 to be arranged on cutter head 7 and cutter head 7 is adsorbed on permanent magnet; firm difficult drop-off is installed; wearing layer 4 on cutter head 7 protects cutter head 7 in the cutter course of work; improve the anti-wear performance of cutter head 7; the wear-resistant block 3 on handle of a knife 1 top makes cutter in work progress, avoid direct extraneous native stone friction; the anti-wear performance of wear-resistant block 3 is high, improves the application life of handle of a knife 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
