Abstract
The invention discloses a seabed polymetallic sulfide cutting head. In the cutting head, multiple symmetrical cutters are adopted to cut a polymetallic sulfide at the same time; when the cutting head works, adjacent cutters rotate in opposite directions. When the adjacent cutters rotating oppositely cut a polymetallic sulfide ore body, the stress mode of the polymetallic sulfide ore body is changed so that the polymetallic sulfide ore body is broken easily. Meanwhile, since the polymetallic sulfide is porous brittle mineral, after multiple cutting holes are formed in the polymetallic sulfide ore body by the multiple cutters, the polymetallic sulfide between the holes fractures naturally. Compared with a single large-size cutter, the multiple cutters in which adjacent cutters rotate in different directions have the advantages that the stress to the cutting head in the cutting process can be effectively reduced when being used for cutting the polymetallic sulfide ore body at the same time, the power required by the cutting head can be reduced while the cutting efficiency is guaranteed, and the reactive force to the cutting head in the cutting process can be reduced.
Description
Technical field
The present invention relates to a kind of Deep Sea Minerals harvester, be specifically related to a kind of seabed Polymetallic sulphide bit.
Background technology
Seabed Polymetallic sulphide is rich in the metals such as copper, silver, gold, is a kind of deep-sea mineral with very high economic worth.Seabed Polymetallic sulphide is present in the seabed of depth of water 2000-3000 rice conventionally, and chemical forms mostly is large-size massive sulfide.Seabed Polymetallic sulphide bit is the key device in its business exploitation.The reaction force that the design of bit is subject to the energy consumption in working angles and bit has material impact.Test shows, the shear strength of seabed multimetallic sulphide ores body is starkly lower than compressive strength.
The working angles of seabed Polymetallic sulphide completes at abyssal floor, reduces the energy consumption of working angles and contributes to reduce mining cost, reduces reaction force that bit is subject in working angles significant to improving the safety of mining system simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of seabed Polymetallic sulphide bit, to solve the problem proposing in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of seabed Polymetallic sulphide bit, comprises base, cutterhead and blade; On described base, be evenly provided with multiple cutterheads, cutterhead end face is evenly provided with multiple blades; When bit work, the cutterhead direction of rotation of adjacent layout is contrary.
Further, the quantity of described cutterhead is even number, and cutterhead quantity is no less than 4.
Further, described blade quantity is no less than 3.
Compared with prior art, beneficial effect of the present invention:
The present invention adopts multiple cutterheads that are arranged symmetrically with to cut Polymetallic sulphide cleverly simultaneously, when bit work, the cutterhead direction of rotation of adjacent layout is contrary, change the stress form of cutterhead multimetallic sulphide ores body in the time of cutting multimetallic sulphide ores body, make multimetallic sulphide ores body more easily broken, both reduce the required energy consumption of the bit in working angles, reduced again the reaction force that in working angles, bit is subject to.

The specific embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
A kind of seabed Polymetallic sulphide bit, comprises base 1, cutterhead 2, blade 3; Described cutterhead 2 is arranged symmetrically in the end face of base 1, and blade 3 is evenly arranged in the end face of cutterhead 2; When bit work, the direction of rotation of adjacent cutterhead 2 is contrary; In bit when work,, the multimetallic sulphide ores body between adjacent cutterhead is mainly subject to shear force, and because the shear strength of seabed multimetallic sulphide ores body is lower than compressive strength, it is easy that the cutting of multimetallic sulphide ores body becomes.Meanwhile, because seabed Polymetallic sulphide is concrete dynamic modulus brittle mineral, when multiple cutterheads produce after multiple cutting holes on multimetallic sulphide ores body, the Polymetallic sulphide between adjacent cutting hole can more easily rupture.Compared with adopting single large scale knife cutting Polymetallic sulphide, adopt multiple small size cutterheads to cut simultaneously and contribute to reduce the resistance that in working angles, bit is subject to, in realizing identical stock-removing efficiency, the required power of bit can be reduced, and the reaction force that in working angles, bit is subject to can be reduced.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the present invention.
In addition, be to be understood that, although this manual is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should make manual as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
