Description
Technical field
The invention belongs to fishery Fishing technology field, more particularly to a kind of improved Eriocheir sinensis otter-trawl dredger
, the dredger can utilize the steel suspension bracket lifting being fixed in the middle part of dredger fore deck and decentralization Eriocheir sinensis otter-trawl
Mesh bag, Eriocheir sinensis tradition trawl fishing ship is received into net operation process mechanization.
Background technology
Eriocheir sinensis is one of the current Yangtze river basin migratory species that can still form stable fishing season few in number, often
After the first tenday period of a month in late September to October in year enter flood season, Eriocheir sinensis progressively carries out breeding migration to entrance of Changjiang River.It is existing to catch
The mode of dragging for is mainly otter-trawl operation, and otter-trawl is made up of main push-towing rope rope, bifurcated hawser, supporting steel pipe and mesh bag.Eriocheir sinensis
Migration colony is mainly through river course deep trouth migration, therefore the main push-towing rope rope of existing otter-trawl is typically for up to tens of rice, while in order to make
Mesh bag remains patch bottom during trawl, and existing mesh bag bottom margin generally hangs a large amount of iron pendants to increase mesh bag weight
Amount.Traditional operating type is entirely manual work, main push-towing rope rope is pulled using manpower by crewman, after main cable end is drawn to
Pull bifurcated hawser upwards simultaneously by two people, to supporting steel pipe water outlet after two people be lifted up mesh bag simultaneously until complete water outlet.
Above-mentioned operation process expends a large amount of manpowers, therefore usually requires to be equipped with 4 blue or green strong labour powers on every dredger.Nearly ten years, in
There is a certain degree of technological improvement in magnificent Eriocheir otter-trawl dredger, and irony roll shaft is housed in dredger proostracum prelaminar part,
Using small horsepower diesel engine band action roller shaft, main push-towing rope rope is pulled using mechanical force, reduces manpower demand.But due to main cable end
It is below bifurcated hawser, two sections are individually fixed in supporting steel pipe both ends, roll shaft can not be utilized to be lifted.Therefore, up to the present, still
So bifurcated hawser, supporting steel pipe and mesh bag can only be pulled with manpower.For the trawlnet structure used at present, as shown in Fig. 2 point
It is about 3m to pitch hawser 26 to the height between supporting steel pipe A 24, and the connection between supporting steel pipe A 24 and supporting steel pipe B 25 is pulled
27 length of restricting are about 6m, and supporting steel pipe B is highly about 2m below 25, i.e., the distance pulled at present using two labours is exceeded
10m, it is still required for more personnel's input.In order to further reduce the manual work in Eriocheir sinensis otter-trawl operation process
Intensity, catching rate is improved, reduce human cost, it is proposed that a kind of improved Eriocheir sinensis otter-trawl dredger.
The content of the invention
Present invention aims at the deficiency for existing fishing style, there is provided it is strong that one kind can reduce artificial fishing as far as possible
Degree, the improved Eriocheir sinensis otter-trawl dredger for improving catching rate.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of Eriocheir sinensis otter-trawl dredger, including otter-trawl, fishing hull；The otter-trawl include main push-towing rope rope,
It is connected to the bifurcated hawser, the supporting steel pipe being connected with bifurcated hawser and the mesh bag being connected with supporting steel pipe of main cable end；Its
It is characterised by：The bifurcated hawser of the otter-trawl is to being provided with multiple withhold between mesh bag；It is provided with and hangs on the fishing hull
Frame, the suspension hooks of two alternately linkage liftings are provided with the suspension bracket.
It is further characterized by：The suspension bracket top is provided with two pulleys；Two suspension hooks pass through two-way elevator
Machine drives, and is connected respectively by two strand steel wire ropes between two suspension hooks and two-way hoist engine, two bursts of steel wire rope difference pile warps
The pulley.
Further：Respectively on the two-way hoist engine bobbin, two strand steel wire ropes are wound two strands of steel wire ropes
In the opposite direction.
Preferably：The suspension bracket includes two isometric steel pipes, the long 5m of steel pipe, internal diameter 5cm；Two steel pipe bottom difference
It is welded in the middle part of fishing hull fore deck, two steel pipe top welding, drift angle are 45 degree.
The two-way hoist engine controls rotating by two-direction switch.
Present invention tool has the advantage that：
Under limited steric requirements, a liter trawlnet mesh bag is hung by Double-pulley device cycle alternation, significantly reduces China
Manual work intensity of the Eriocheir tradition trawl fishing ship during operation, reduces crewman's quantity needed for dredger, improves
Catching rate, saves cost of human resources.

Embodiment
A kind of Eriocheir sinensis otter-trawl dredger includes fishing hull and otter-trawl as shown in Figure 2.
As shown in Figure 1 suspension bracket and hoisting mechanism are provided with fishing deck in ship structure.
（1）Suspension bracket is made up of two isometric steel pipes 1, steel pipe 1 length 5m, internal diameter 5cm, is fixed on fishing hull fore deck
In the fixed plate 10 at middle part, two drift angles of steel pipe 1 are 45 degree.
（2）Two pulleys 2 are fixed with below two top attachment points of steel pipe 1.
（3）Hoisting mechanism includes suspension hook 5 and suspension hook 6, steel wire rope 3 and steel wire rope 4, two-way hoist engine 7.Steel wire rope 3 and steel
4 long 10m of cord, difference pile warp pulley 2, suspension hook 5 and suspension hook 6 are assembled in two strand steel wire rope one end respectively, and the other end is fixed on two-way
On the bobbin of hoist engine 7, two strand steel wire rope coiling directions are opposite.
（4）Two-way hoist engine 7 is fixed in fixed plate 10, can be turned as desired by the switching of two-direction switch 8 of hoist engine
Dynamic direction is to lift or transfer suspension hook 5 and suspension hook 6, so as to realize the raising and lowering of trawlnet mesh bag.
Otter-trawl as shown in Figure 2 is withheld by main push-towing rope rope 20,26, three, bifurcated hawser（A 21 is withheld, B 22 is withheld, hangs
Detain C 23）, two pieces supporting steel pipes（Supporting steel pipe A 24, supporting steel pipe B 25）And mesh bag 28 forms.The one end of bifurcated hawser 26 leads to
Cross and withhold A 21 and be connected to main cable end, the other end is connected to the both ends of supporting steel pipe A 24.Supporting steel pipe A 24 and supporting steel
Pipe B 25 is connected by connection cable 27, the connection mesh bags 28 of supporting steel pipe B 25.The middle part of connection cable 27 and supporting steel pipe B 25
On be connected to bifurcated hawser 26, the one end of bifurcated hawser 26, which is respectively arranged with, withholds B 22 and withholds C 23.
When carrying out Eriocheir sinensis fishing using the present invention, the two-direction switch 8 of two-way hoist engine 7 is first turned on, will be assembled
Suspension hook 5 in the end of steel wire rope 3 is transferred to ship side height, is caught on the bifurcated hawser shown in Fig. 2 and withholds A 21, opened two-way
Hoist engine 7, steel wire rope 3 is set to be in winding state, so as to sling supporting steel pipe A 24；B is withheld on connection cable 27 to be located at
After 22 water outlets, the suspension hook 6 for being assemblied in the end of steel wire rope 4 is caught on and withholds B 22, two-way hoist engine 7 rotates backward, and continues net
Bag 28 above carries and disengages it from withholding A 21 during suspension hook 5 declines；Withhold C in the tops of supporting steel pipe B 25 to be located at
After 23 water outlets, 5 will be withheld catch on and withhold C 23, two-way hoist engine 7 switches rotation direction again, and mesh bag 28 is promoted into dredger
Fore deck；Two-way hoist engine 7 switches rotation direction, and mesh bag 28 is transferred to deck.So that for the trawlnet that uses at present, circulation carries
Deck can be promoted to by mesh bag by rising 3 times, even if the connection cable between part waters supporting steel pipe A and supporting steel pipe B is longer,
It need to only increase on connection cable and withhold and can solve.
