Abstract
The invention discloses a novel net for catching Venerupis philippinarum and belongs to catching of shellfishes in the marine aquaculture industry. The net is characterized in that a steel frame is provided with rope hooks, a water pump is disposed on the middle surface of the steel frame, the lower end of the water pump is connected with a spray pipe extending into the steel frame and nozzles, a steel mesh is arranged on the surface of the lower end of the steel frame, and a plastic mesh is connected to the lower end of the steel mesh. The novel net in the structure of the rigid frame-net and the flexible mesh is simple in structure and convenient and reliable to use; the novel net is mechanically driven to catch Venerupis philippinarum. The novel net saves the labor of manually catching Venerupis philippinarum; catching the Venerupis philippinarum is low in cost and convenient to operate; a technique of catching the Venerupis philippinarum is easy to master, easy to popularize and highly operable; manpower resource can be saved, and labor is less intensive. Therefore, the intended purposes are achieved.
Description
Technical field
The present invention relates to the instrument that the shell mariculture industry is fished for, specifically a kind of novel netting gear of fishing for colored clam.
Background technology
The cultivation of flower clam is long at Chinese history, and Jiangsu, Zhejiang, Fujian are in the 6-7 month, and Guangdong, Guangxi are in the 5-7 month.Flower clam cultivation because of small investment, cost is low, output is high, profitable, be a good mariculture kind be worthy to be popularized.The flower clam has strong adaptability, feeding habits are wide, disease is few, easy breeding, the advantages such as growth is fast, output is high, meat delicious flavour, and flower clam cultivation place should be chosen in nature sandy beach, sea area trend little (the trend conference causes a large amount of losses of colored clam), sandy beach, and area is large in flakes, the grains of sand are thin, the sandy beach between the seawater salinity 5%-30% of sea area.Existing harvest method: have hoe to wash method, hand rake method etc.Hoe is washed method: be applicable to substrate containing the more field of razor clam ground of mud, the some communities that the clam field of razor clam are divided into to 0.1 mu of left and right, in its surrounding, erect high 20 centimetres, the little dike of wide 30-40 centimetre, stay on the dike in low place on a discharge outlet oblique cutting and put the clam curtain in physical features, the clam basket is put in the back of curtain, while gathering, dig silt and flower clam with rake teeth, the seawater stored up in advance above crucible ground is put into, with tooth harrow or triangle hoe, constantly stir into mud, the flower clam is together with silt process clam curtain, water and silt are missed, and the flower clam is packed in basket, cleans, chooses impurity removing.Hand rake method: with tooth harrow, earth band clam is dug, choose and push away ten flower clams.In addition, the colored clam of the subtidal zone of gathering, fish for the special clam rake with the string bag and tooth harrow.Work efficiency is low like this, and labour intensity is large, and fishing for colored clam needs a large amount of manpowers.As run into the flower clam cultivation of large-area seabeach, just be difficult to harvest.How to overcome existing deficiency of fishing for colored clam technology, become the current technical problem that must solve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the objective of the invention is manually to fish on the basis of colored clam existing, propose a kind of structure of using rigid mount and net to combine with flexible net, and simple in structure, easy to use and reliable, driven the novel netting gear of fishing for colored clam of its operation by machinery.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel netting gear of fishing for colored clam, it is characterized in that: a steelframe is arranged, be provided with the rubbish rope hook on steelframe, the steelframe intermediate surface is provided with water pump, the water pump lower end is connected with and stretches to steelframe middle sparge pipe and shower nozzle, the steelframe rear surface is laid with steel mesh, and the lower end of steel mesh is connected with plastic wire.
Described steelframe is three-dimensional firm iron cage or claims the steel cage, generally by the construction material reinforcement fabrication.
Its power supply of described water pump is provided by dredger.
The course of work of the present invention is provided by embodiment.
The invention has the beneficial effects as follows: the present invention can replace manually fishing for the arduous of colored clam, and it is low, easy to operate to fish for colored clam cost, and technology is easy to grasp, and is easy to popularize, workable, can also save human resources, reduces labor intensity.Therefore, the present invention can reach the expection purpose.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Fig. 1 is structural representation view of the present invention.
1 steelframe in figure, 2 steel meshes, 3 plastic wires, 4 rubbish rope hooks, 5 sparge pipes, 6 shower nozzles, 7 water pumps.
Embodiment
Embodiment 1:
A steelframe 1 is arranged, be provided with rubbish rope hook 4 on steelframe 1, steelframe 1 intermediate surface is provided with water pump 7, and water pump 7 lower ends are connected with and stretch to steelframe 1 middle sparge pipe 5 and shower nozzle 6, and steelframe 1 rear surface is laid with steel mesh 2, and the lower end of steel mesh 2 is connected with plastic wire 3.
The present embodiment arranges that one long 4 meters, wide 3 meters, front are high 0.5 meter, the firm steelframe 1 (iron cage or steel cage) of the solid of high 0.8 meter of back.A high pressure water jet pipe 5 with 10 centimetres of the long balance diameters of bottom face broadside is set at 1 meter of iron cage bottom face two length of sides, the unanimously high-pressure nozzle 6 of (50-100 props up) of one row's direction is set on whole high pressure water jet pipe, and the direction of shower nozzle 6 is downward and become miter angle with bottom face.The centre of high pressure water jet pipe 5 arranges an interface, for high-voltage tube, being connected electric water pump.In iron cage back, (high 0.8 meter) installs a plastic wire 3 that can fill the 500-1000 kilogram.During flower clam fishing operation, first rubbish rope hook 4 places in the middle of the front of this netting gear (high 0.5 meter), setting certain-length with steel wire connects tightly on dredger, this netting gear is placed in the seawater at cultivation flower clam seabeach, start and be arranged on the electric water pump on this netting gear, then start lentamente dredger, dredger wants straight line slowly to haul this netting gear.At this moment high-pressure nozzle 6 beginnings are washed away to the mud under iron cage bottom face, scour depth can reach 30-50 centimetre, result is rolled mud together with the flower clam, at this moment due to this netting gear slowly pulling and advancing at fishing boat, in the plastic wire 3 that just can be connected these mud that rolls together with the lower end of spending clam to bring steel mesh 2 into, in constantly pulling and advancing, mud spills outside net, remaining flower clam in net.When net is filled colored clam, with fixed pulley on ship, whole netting gear on rubbish, is poured in ship together with the plastic wire 3 of filling colored clam.Repeat like this, just can replace manually fishing for colored clam.
