Embodiment

[0034] A kind of realization mode of the technical scheme provided by the present invention is:

[0035] Such as figure 1 and figure 2 As shown, a semi-mechanized large-scale seafood fishing device is characterized in that it includes:

[0036]The net-spreading part includes a launching frame 2, which is an inverted trapezoidal frame body, and the middle part of the upper frame 9 of the launching frame protrudes to a direction at a certain angle with the plane where the launching frame is located to form an arc-shaped lifting part. The lower frame 12 of the launching frame is an arc-shaped frame protruding toward the upper frame direction, and the lower frame has a cavity with a polygonal cross-section extending along its length; at least two through holes are arranged at the lower end in parallel and spaced apart. On the side wall of the frame, the cavity communicates with the outside world, and the opening direction of at least two through holes is consistent with the arc...

Abstract

The invention belongs to the technical field of seafood capturing, and particularly relates to a semi-mechanized large-scale seafood capturing device which comprises a launching frame, at least two through holes, a connecting rod, an elastic rope, a launching body and a capturing net containing portion. The launching frame is an inverted-trapezoid frame, the through holes are formed in the side wall of a lower-end frame in a parallelly spaced manner, the connecting rod is arranged in a cavity of the lower-end frame of the launching frame, two ends of the elastic rope are fixedly connected with two ends of an upper-end frame of the launching frame respectively, the launching body is a columnar body, the capturing net containing portion is a frame with a rotating shaft inside, a capturing net is wound on the rotating shaft, and one end of the capturing net is fixedly connected with a net fixing end of the launching body to enable the launching body after being launched by the launching frame to drive the capturing net to rotate out from the rotating shaft and outwards unfold to complete net casting. The semi-mechanized large-scale seafood capturing device is simple in structure and reasonable in design, net casting and net recovering can be completed within short time, needs on large-scale seafood capturing are met, and working efficiency can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a semi-mechanized large-scale seafood fishing device. Background technique [0002] As the name suggests, fishing nets are nets for fishing. At present, most fishing nets are made of synthetic fibers. In ancient times, people used coarse cloth and hemp as raw materials to make fishing nets by bundling. Although this fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. [0003] The nets used in fishery production include trawl nets, seine nets, casting nets, fixed nets and cages. Trawls and seines are heavy-duty nets used in marine fisheries. The mesh size is 2.5-5 cm, the diameter of the net rope is about 2 mm, and the weight of the net is several tons or even tens of tons. Usually, a ...
