Description
Technical field
The invention belongs to technical field of aquaculture, particularly device fished for by the extensive marine product of a kind of semi-mechanization.
Background technology
The net that namely fishing net is fished as its name suggests, current most fishing net adopts synthetic fibers to process, and in ancient times, people use coarse cloth and fiber crops as raw material, and the method for being rolled up by bundle makes fishnet.Although this fishing net is perishable, toughness is poor, and its fishing efficiency improves greatly.Along with the development of fishery, the object of fishing and hunting is not fish, and the instrument of fishing for also grows with each passing hour.
The netting gear of fish production, has trawlnet, purse seine, casts net, set net and net cage etc.Trawlnet and purse seine are the heavy netting gear that sea fishery is fished for.Mesh size is 2.5 ~ 5 centimetres, and nettle diameter is 2 millimeter, and net weighs several tons of even tens of tons, usually with a pair tugboat separately tractive chase the shoal of fish or lure the shoal of fish concentrated by fishing light boat and surround.Cast net to fish for for rivers and lakes and use light-duty netting gear.Mesh size is 1 ~ 3 centimetre, nettle diameter 0.8 millimeter, net tuple kilogram.Set net and net cage are that fixing netting gear is propagated in lake and reservoir or bay artificially.Size specification, according to institute's class of breeding fish and different, cuts tuck seine to cultivate in certain waters and does not make to flee from.But at present for the fishing net of marine fishing due to the deficiency of configuration aspects, artificial throw net time be not easy to throw enough far away, and cause fisher to be escaped not rapidly and easily when receiving net.
Summary of the invention
An object of the present invention is, the extensive marine product of a kind of semi-mechanization is provided to fish for device, this device can will fish for one end throwing quickly and accurately of net to target location under the cooperation of launcher and emitter, and completes rapidly throwing net under the cooperation of rotating shaft;
Two of object of the present invention is, the extensive marine product of a kind of semi-mechanization is provided to fish for device, realize effectively receiving network process rapidly by the fast rotational of rotating shaft in the process of fishing for, can fast the marine product of fishing in net be carried out fishing for loading under the cooperation at other ships in receipts network process, fisher can not be caused to escape.
To achieve these goals with some other objects, technical scheme provided by the invention is:
Device fished for by the extensive marine product of a kind of semi-mechanization, it is characterized in that, comprising:
To cast net portion, it comprises launcher, it is upside-down trapezoid support body, portion is lifted to the raised arc that formed in plane direction at an angle, described launcher place in the middle part of the upper end frame of described launcher, the lower end frame of described launcher is to the raised arc-shaped frame in frame direction, upper end, and the cross section in the frame of lower end with upper extension is along its length polygonal cavity; At least two through holes, its parallel interval open be arranged on lower end frame sidewall on, described cavity is in communication with the outside, and the opening direction of at least two through holes is consistent with described arc-shaped protrusions direction of lifting portion, wherein, at least one through hole is arranged on the middle part of lower end frame; Connecting rod, it is arranged in the cavity of described launcher lower end frame, with at least two projections in described link sidewalls, at least two protrude through described at least two through holes extend the cavity of described launcher lower end frame respectively; Stretch cord, its two ends are fixedly connected with the frame two ends, upper end of described launcher respectively, and the upper end frame length of the natural length of described stretch cord and described launcher adapts; Emitter, it is cylindrical body, and emitter front end is arrow shaped, and a part of projection of the lower surface of emitter rear end is fixed network side, and the relatively non-projection of remainder is emitting side; The upper end frame of described launcher and the vertical range of lower end frame are less than the length of emitter;
Fish for net holding part, it is the framework of an inside with rotating shaft, fish for net and be wound around on the rotary shaft, and the fixed network end of the one end and emitter of fishing for net is fixedly connected with, with make emitter to be launched by launcher after drive and fish for net and screw out and outside spread apart from rotating shaft, complete and cast net.
In such scheme, when operation casted net by needs, first by with the emitter of fishing for net
Front end is placed in the portion of lifting, the fixed network side of the projection of emitter rear end is placed on the lower end frame of launcher, the emitting side of emitter is made to be fastened on the inside edge of lower end frame, now, stretch cord is drawn in the projection in the middle part of connecting rod stretches and is hung on by stretch cord, and this projection and emitting side are just right, now, Job readiness of casting net is ready, the projection of stretch cord is not hung in manual operation pressing, due to the effect of connecting rod, drive the projection hanging with stretch cord simultaneously in retraction cavity, make stretch cord resilience, hit in springback process in emitting side, emitter is driven to launch from launcher, thus drive fishes for net from rotating shaft back-out also outside spread apart, complete and cast net, when net is fished in needs recovery, can manually or driven by power rotating shaft will fish for net and wind up, reclaim, speed of packing up is fast and clean and tidy, and fishes for net and be placed in order, and saves the space that it takies, stretch cord is arranged on the downside of launcher, and fish for net under the drive of emitter, the upper side of launcher extends out, non-interference, operation is smooth and easy,
