Embodiment Construction

[0032] Referring to the accompanying drawings, the present invention will be further described.

[0033] A sea fishing single-vessel purse seine hoist, the purse seine hoist has a left-right symmetrical structure;

[0034] On the deck, a group of gear reduction boxes A are respectively fixed on the left and right sides, and a horizontal main shaft 10 is arranged transversely and fixedly in the gear reduction boxes A on the left and right sides;

[0035] In the gear reduction box A on each side, an intermediate shaft sleeve 15 that can move axially is placed on the main shaft 10, and the outer end of the intermediate shaft sleeve 15 is fixedly connected with the large cylindrical gear 5 with a key 14, and the large cylindrical gear 5 meshes with the small cylindrical gear. The gear 2 and the cylindrical pinion 2 are driven by the hydraulic motor 1; the inner end of the intermediate shaft sleeve 15 is fixedly connected to the active pawl 11 of the jaw clutch D;

[0036] The int...

Abstract

The invention relates to a marine fishing single ship bag seine net hauler which is of a bilaterally symmetric structure. The net hauler is characterized in that a horizontal main shaft (10) passes through gear reducers (A) on left and right sides, and a middle shaft sleeve (15) is hollowly sleeved on the main shaft (10);a cylindrical big gear wheel (5) is fixed connected with the outer side of the middle shaft sleeve (15), is meshed with a cylindrical small gear wheel (2) and is driven by a hydraulic motor (1); the middle shaft sleeve (15) is fixedly connected with a driving claw (11) of a claw clutch (D), and a shifting yoke (E) can shift a coaxially arranged driven claw (19) of the claw clutch (D), which can be meshed or separated; the driven claw (19) is fixedly connected with a net-placing roller (20), and the diameter of an outer side plate (18) of the net-placing roller (20) is greater than that of an inner side plate (21); and the left and right two inner side plates (21 and 22) are closed to each other, the diameter of the inner side plate (21) on one side is slightly large, and a section of annular barrel sheet (25) extends out in the axial direction of the inner side plate (21) to cover the inner side plate (22) at the other side. The invention provides equipment by which a single bag seine fishing boat realizes high-efficiency fishing and the equipment is simple and compact in structure and convenient to operate and use.

Description

technical field [0001] The invention relates to a fishing device used for marine fishery machinery, in particular to a net-lifting device for a single-vessel purse-seine fishing operation in marine fishing. Background technique [0002] Due to unreasonable fishing methods, bottom trawling is still the main operation at present, and bottom fish are overfished, resulting in the reduction of ocean bottom fish resources, while the development of upper fish still has potential. In order to improve the fishing efficiency of pelagic fish in the ocean, it is an effective method to use light lure fish seine operation; light lure fish single-vessel purse seine is a relatively simple operation method of seine operation, and it is also a This kind of equipment composition is relatively simple, and the fishing efficiency is more efficient. It has the common advantages of trawling and seine, so it is also called "seine trawling". Therefore, there is an urgent need to research and develop...
