Abstract
The invention relates to a combined rock breaking knife tooth for a dredge boat and belongs to the technical field of dredging. The combined rock breaking knife tooth for the dredge boat is characterized by comprising a knife tooth mother body (1) and a hard alloy body (2), wherein a hole (3) is formed in the tooth tip of the knife tooth mother body (1); the hard alloy body (2) is inlaid in the hole of the tooth tip of the knife tooth mother body (1); and the hard alloy body (2) and the knife tooth mother body (1) form the rock breaking knife tooth with composited structures. The combined rock breaking knife gear has the advantages of simple structure, high abrasive resistance, high shock strength, uneasiness in breaking during rock breaking of the knife tooth, long service life, high production efficiency of construction, capability of improving the rock breaking ability greatly and the like.
Description
Technical field
The invention belongs to the dredging technology field, particularly relate to a kind of dredge boat with compound broken rock cutter tooth.
Background technology
At present, the ocean-going freighter tonnage is increasing, absorbs water more and more deeplyer, just requires the navigation channel to dig darker and darker, and it is harder that the excavation soil property also more becomes, by original mud, clay become strong-weathered rock even in decomposed rock.In a single day meet with hard rock in work progress, the dredge boat cutter tooth weares and teares, fracture is serious, programming is slow, causes the construction period not guarantee, causes huge economic loss.
Cutter tooth factory (as companies such as Vosta, Esco) attempts the good cutter tooth of exploitation anti-wear performance, mostly adopt alloy steel to improve material hardness, anti-wear performance increases, but hardness improves to sacrifice the cutter tooth impact strength as cost, therefore can only do balance between abrasion resistance and impact strength, therefore the Wear Resistance of developing can increase, but not than quantum jump.Many dredging enterprises have also found to dig the problem that the rock cutter tooth wears no resistance aborning, in order to increase the application life of cutter tooth, they are at cutter tooth surface overlaying high-abrasive material, although can increase like this application life of cutter tooth, but it is bothersome that existence is taken a lot of work, increase constructor's working strength, there is no the too large technical problems such as economic benefit.
Summary of the invention
The present invention provides a kind of dredge boat with compound broken rock cutter tooth for solving the technical problem that exists in known technology.
The purpose of this invention is to provide a kind of under the operating mode of excavating rock, anti-wear performance is good, easy fracture not, has form of structure simple, abrasion resistance is good, excellent in cushion effect, the broken rock of cutter tooth is easy fracture not, can significantly improve rock breaking capacity, and the dredge boat of construction production efficiency high is with compound broken rock cutter tooth.
The present invention is in crown place's perforate; with carbide mosaic in the crown perforate; utilize that Cemented Carbide Hardness is high, abrasion resistance good; improve the cutter tooth life-span; and crown parent material pliability is good, shock resistance; the protection carbide alloy prevents the cutter tooth fracture, and this compound broken rock cutter tooth possesses good, the excellent in cushion effect characteristics of abrasion resistance simultaneously.
The technical scheme that dredge boat of the present invention is taked with compound broken rock cutter tooth is:
A kind of dredge boat is with compound broken rock cutter tooth, be characterized in: broken rock cutter tooth comprises cutter tooth parent and cemented carbide body, the perforate of cutter tooth parent crown section, cemented carbide body are embedded in the perforate of cutter tooth parent crown section, and cemented carbide body and cutter tooth parent are composite structured broken rock cutter tooth.
Dredge boat of the present invention can also adopt following technical scheme with compound broken rock cutter tooth:
Described dredge boat is characterized in compound broken rock cutter tooth: the shape of cutter tooth parent crown section perforate can be circle, square, ellipse or triangle.
Described dredge boat is characterized in compound broken rock cutter tooth: the section area of cutter tooth parent crown section perforate is 0.2-15cm
2
Described dredge boat is with compound broken rock cutter tooth, and be characterized in: cemented carbide body is bar-shaped, and cross sectional shape is circular, square, ellipse or triangle.
Described dredge boat is with compound broken rock cutter tooth, and be characterized in: the cemented carbide body section area is 0.2-15cm
2
Described dredge boat is characterized in: the hardness HRC10-55 of cutter tooth parent, toughness 10-50J/cm with compound broken rock cutter tooth
2
Described dredge boat is characterized in: the hardness HRC50-100 of cemented carbide body, toughness 1.0-10J/cm with compound broken rock cutter tooth
2
