Embodiment Construction

[0015] The invention is mainly composed of a fish suction pump (1), a fish pump crane (4), a net bag winch (5), a fish pump hydraulic station (6) and a fish water separator (8). Above-mentioned equipment is all installed on the fishing boat deck (10), and wherein fish pump (1) is movable, is locked on the special support of operating platform when not operating at ordinary times.

[0016] After the towing process finished the fishing goods into the net, the net body (3) was mostly dragged to the deck, and the fishing goods were concentrated in the net bag (2). The operator pulls the net bag (2) tail to the operating platform of the deck (10) through the net bag winch (5), then opens the net bag (2) tail, and is connected with the fish suction port of the fish suction pump (1) Together, the fish pump (1) is lifted into the sea by the fish pump crane (4) again.

[0017] The fish pump (1) is driven by the fish pump hydraulic station (6) through the hydraulic hose (7), sucks the ...

Abstract

The invention relates to a technology of absorbing fish by a cod end used for the trawl fishing of a large distant-water trawler, and belongs to the fields of farming, forestry, husbandry, and fishing. During a good harvest fishing time, large net heads of large trawlers used for catching scads in the south pacific and catching haddock in the north pacific can be frequently used for catching 500-600 tons fishing goods by a single net, and the weight of caught fishing goods by a single net sometimes can even reach up to 800 tons. Each large net head contains too many fishing goods, so that the fishes in each cod end are impossible to be directly pulled on a deck of the trawler. The technology of absorbing fish by cod end adopts an axial-flow type fish absorbing pump driven in a hydraumatic manner to directly absorb fish in the cod end into a fishhold of the trawler.

Description

Technical field [0001] The invention relates to trawling by a large ocean-going trawler, in particular to a technique for sucking fish in a mesh bag during trawling by a large ocean-going trawler. It belongs to the field of agriculture, forestry, animal husbandry and fishery. Background technique [0002] Large ocean-going trawler, slideway operation mode, fishing boats generally have two to three decks. When the fishing operation is lifting the net, when part of the net bag enters the tail of the deck through the stern slideway, the mast hook is used to lift the net bag. There is a hydraulically opened movable door under the rear mast of the fishing boat, and the catch can be poured directly into the fish hold on the lower deck. When there are many catches, the net bag needs to be dragged onto the deck through the pulley of the bollard on the side of the ship. [0003] The above-mentioned operation method not only takes a long time to lift the net, but also needs to be e...
