Abstract
The utility model provides a cutter of a shield machine. The cutter of the shield machine comprises a cutter body, a row of cutter milling bodies at the top edge of the cutter body, and a plurality of round milling bodies on the back sides of the cutter milling bodies; two recessed holes are formed in the front side surface of the cutter body, and the recessed holes are formed along the length direction of the cutter body; the round milling bodies are arranged like a curve along the length direction of the cutter body. The cutter of the shield machine, provided by the utility model, can be fully distributed on a cutting body along the radial direction of the shield machine, so that cutting points exist everywhere and the special structure of the cutter milling bodies enhances the cutting force.
Description
Technical field
The utility model relates to a kind of shield machine cutter, belongs to field of mechanical technique.
Background technology
Existing shield machine cutter form of structure is varied, and the design of its architectural feature is studied along the structural strength direction of higher cutting force and Geng Gao nothing but.Structure design whether rationally for judging the key index of shield machine ability to work.
Utility model content
For solving above technical problem, the utility model provides a kind of shield machine cutter, and smear metal power is stronger, and structural strength is higher.
The utility model provides following technical scheme: a kind of shield machine cutter, described shield machine cutter comprises that the cutter body of cuboid, the edge of cutter body upper surface radially fix row's cutter mill body along its length, and described upper surface is positioned at the fixing multiple round mill bodies in described cutter mill body rear; Described round mill body is arranged along the curved shape of cutter body length direction, and the height of described round mill body is less than or equal to the height of described cutter mill body.
Further, described round mill body is hemisphere or billiard table.
Further, the scope of operation of described cutter body has the gradient, and its cross section is right-angled trapezium.
Further, the front of described cutter mill body is the structure of a middle part protuberance.
Further, the back side of described cutter mill body is a middle part ridge structure, with positive symmetrical configuration.
Further, described cutter body leading flank has two pit-holes, and the hole week of pit-holes has circular slope, and the aperture of circular slope is greater than the aperture of pit-holes.
Further, the material of described cutter is wolfram steel.
This shield machine cutter that the utility model relates to, along the radially discontented cutting body of shield machine, therefore its cutting point is without can't be obtained, and the special construction of cutter mill body has strengthened cutting force.
Brief description of the drawings
Fig. 1 is the utility model shield machine cutter elevation;
Fig. 2 is the utility model shield machine cutter lateral view;
Fig. 3 is the utility model shield machine cutter top view.
Detailed description of the invention
As shown in Figure 1, a kind of shield machine cutter, described shield machine cutter comprises row's cutter mill body 2 at cutter body 1, cutter body top place and the multiple round mill body 4 of cutter mill body rear side; Described cutter body 1 leading flank has two pit-holes 3, and pit-holes 3 is arranged along cutter body length direction; Described round mill body is arranged along the curved shape of cutter body length direction.
Circle mill body 2 end faces are that semicircle is spherical.
The front of cutter body 1 has the gradient, and its cross section is right-angled trapezium.
The front of cutter mill body 2 is the structure of a middle part protuberance.
The back side of cutter mill body 2 is a middle part ridge structure 21, the symmetrical configuration positive with it.
Cutter mill body equates with the height of circle mill body.
The hole week of pit-holes has circular slope 31, and the aperture of circular slope 31 is greater than the aperture of pit-holes.Pit-holes is used for being installed on shield machine chain-drive section, because its installation portion (cutter body) is wedge shape, brings conveniently for installing, and card edge type connects, and its pit-holes is for having installed fixation.
The material of cutter is wolfram steel.Wolfram steel is a kind of hard alloy steel of tungstenic, and its hardness is high, although its toughness is poor, is particularly useful in this plant equipment of working continuously.Its cost is lower with respect to diamond price, and therefore cost performance is higher.
Detailed description of the invention described in the utility model does not form the restriction to the application's scope; every within the spirit and principle of the utility model design, any amendment that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
