A kind of fishpump fish-aggregating device for net cageTechnical field
The invention belongs to fishery equipment technical fields, are related to a kind of fishpump fish-aggregating device for net cage.
Background technique
Currently in aquaculture, especially in large-scale aquaculture pond and the cultivation of Largesize deepwater net cage Base environment, due to supportingGrow that scale is increasing, the yield for cultivating fish is also higher and higher, and current single a Largesize deepwater net cage can cultivate 10 to 50 tonsFinished product live fish, therefore when fish is brought up, it is necessary in time live fish is caught out and sell, to guarantee the economic benefit of cultivation, butThis large amount of finished product live fish will be caught up, and keep higher survival rate, due to unsuitable machinery rapidly and efficientlyChange and receive fish equipment, fishing fish is a very big problem, currently can only receive fish using artificial, or using crane type equipment with hanging basket comeFish is received, not only receives fish heavy workload in this way, the receipts fish speed slow time is long, and also very big to the mechanical injuries of fish, causes to liveThe fish death rate is high, can seriously affect the economic benefit of cultivation, so how fish is received in mechanization rapidly and efficiently, it is current enlargementProblem anxious to be resolved in culture fishery.
Fishpump, especially vacuum fishpump, which are used for from aquaculture net cage or contain in the container of fish, to be drawn fish and then is transmittedTo other places, the working principle of vacuum fishpump is first to vacuumize to a tank body, opened after the vacuum degree for reaching certain intoThe valve of fish port, fish and water mixture are inhaled into tank body from into fish pipe, the valve into fish port are closed after sucking, then again by tankFish in body is transported to cabin etc. by equipment such as pumps.
But since net cage is larger, and pumping fish tube cannot be too big, and the fish in net cage can run chaotically everywhere, this be unfavorable for byIn fish inspiration tank body, clingfish low efficiency.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of fishpump collection for net cage is proposedFish device, the technical problems to be solved by the present invention are: how to improve the clingfish efficiency of fishpump.
Object of the invention can be realized by the following technical scheme: a kind of fishpump fish-aggregating device for net cage, inhalesFish pump includes pumping fish tube, which is characterized in that the fish-aggregating device includes that tapered spiral helicine conveyor screw, institute is arranged in net cageIt states and is equipped with curtain along conveyor screw on conveyor screw, the fish-aggregating device further includes motor one, and the upper of net cage is arranged in the motor oneIt holds and the shaft of motor one is arranged downwards, the shaft of the motor one connect with the conveyor screw and is able to drive spiralBody rotation, the pumping fish tube are extended downwardly into net cage by the axle center of conveyor screw.
The top of net cage is provided with conveyor screw, and the shape of conveyor screw is similar to spiralling volute spring, the spiralThe center line of body axis and net cage is overlapped, and the axis of the shaft of the motor one is also overlapped with the center line of net cage；
Curtain is set between conveyor screw and net cage bottom along conveyor screw, such as can be fishing net, to be formed in net cageTubular conveyor screw, the fish in such net cage are in the helical duct of tubular conveyor screw formation.The clingfish pipe port of fishpumpIt reaching in the water in the middle part of conveyor screw, the top of conveyor screw connects motor one, conveyor screw rotation is driven by motor one, conveyor screwRotation can drive intermediate aggregation of the fish to spiral-tube, be conducive to fishpump clingfish, improve clingfish efficiency.
In the above-mentioned fishpump fish-aggregating device for net cage, the fish-aggregating device further includes a netted block body, instituteIt states block body to extend into from top to bottom in the helical duct that the conveyor screw is formed, the top of block body is connected on a connecting rod, describedConnecting rod is connected on net cage.In order to keep fish-gathering effect more preferable, setting one is perpendicular to barrel in the helical duct that conveyor screw is formedGear mesh body, conveyor screw rotation when, fish can be prevented past and conveyor screw rotation opposite direction run, further improve clingfishEfficiency.
In the above-mentioned fishpump fish-aggregating device for net cage, the connecting rod is equipped with directive wheel, the directive wheel energyIt enough sticks on conveyor screw and can be rolled along conveyor screw.Directive wheel cooperation roll it can along conveyor screw, playGuiding role will not impact the rotation of conveyor screw.
In the above-mentioned fishpump fish-aggregating device for net cage, the connecting rod is telescopic rod.Telescopic connecting rod can be withThe helical position of conveyor screw be changed so that block body is always situated in helical duct, and fish can be driven always to spiral shellIt revolves and collects at the axle center of body.
In the above-mentioned fishpump fish-aggregating device for net cage, the directive wheel is connected to the top of connecting rod, the companyThe bottom end of bar is hinged in a fixing seat, and the fixing seat is connected to the upper end of net cage.Connecting rod can rise with conveyor screw spiralVolt.
In the above-mentioned fishpump fish-aggregating device for net cage, the fish-aggregating device further includes motor two, the motorGear is connected in two shaft, the fixing seat is connected with gear, and the net cage is cylindrical, the upper end edge of the net cageEdge is equipped with gear ring, and the gear ring is engaged with the gear.
The bottom end of the body of rod can also be made to be hingedly connected on gear shaft, the upper end-face edge of net cage, which is provided with, to be engaged with gearGear ring, gear are driven by motor two, to drive block body is autonomous to move along conveyor screw.
In the above-mentioned fishpump fish-aggregating device for net cage, the bottom end ball-joint of the connecting rod is in fixing seat.EvenBar can be around the hinge joint universal rotational of its bottom end and fixing seat.
In the above-mentioned fishpump fish-aggregating device for net cage, the fixing seat is connected in the shaft of motor two, andFixing seat can be rotated coaxially relative to gear around the shaft of motor two.Since the number of teeth of gear obviously will be less than end edge on net cageThe number of teeth of the gear ring of edge, when gear is when net cage upper end is detoured along gear ring, the circle number of rotation is relatively more, by fixing seat and toothWheel is set as non-fixing mechanism, it is possible to reduce the linkage of connecting rod and gear improves the stability used.
Compared with prior art, this use invention has the advantage that
1, the clingfish pipe port of fishpump reaches in the water in the middle part of conveyor screw, and the top of conveyor screw connects motor one, byMotor one drives conveyor screw rotation, and the rotation of conveyor screw can drive intermediate aggregation of the fish to spiral-tube, be conducive to fishpump clingfish, mentionHigh clingfish efficiency.
2, conveyor screw formed helical duct in setting one perpendicular to barrel gear mesh body, conveyor screw rotation when,Fish can be prevented past and run with conveyor screw rotation opposite direction, clingfish efficiency is further improved.
