Trotline type cultured oyster mechanized harvest ship and harvest method thereof

Abstract

The invention relates to a trotline type cultured oyster mechanized harvest ship. A long groove allowing a trotline to penetrate is formed in the middle of a ship body, and a catching device is arranged on the two sides of the long groove. A power tackle is provided with a traction wheel bearing the trotline. A rope guide frame is fixed to the outer side of the traction wheel and inclined outwards from bottom to top for outward putting vertical ropes aside, so that the situation that vertical ropes are wound in the traction wheel is avoided. A crane is used for hoisting the trotline to be hung on the traction wheel. After swinging to the appropriate angle on the vertical face, the rocker arm partitioning plate conveyer bears and conveys the vertical ropes and objects on the vertical ropes. A strong friction structure is arranged on the rocker arm partitioning plate conveyer. A guide wheel is used for guide the trotline to enable the trotline to move backwards along the long groove. The rocker arm partitioning plate conveyer is adopted to bear and covey oysters and attachments on the vertical ropes, so that the operation labor intensity of a seaman is relieved; and the long groove is formed in the middle of the ship body to divide the ship body into left and right parts, corresponding facilities are arranged on the left and right parts, and thus the stability of the ship body is improved.

Description

technical field [0001] The invention relates to a longline type oyster mechanized harvesting ship and a harvesting method thereof, belonging to the technical field of oyster harvesting. Background technique [0002] Oyster artificial breeding generally requires the use of longlines, floating balls, vertical ropes, shell fixing equipment and other components. Oysters are fixed on cages, barbed wire or cement, suspended on the longlines by vertical ropes, and the longlines pass through multiple floating balls. Floating on the sea surface, when it is necessary to salvage the shells, the salvage ship drives to the side of the longline, and hangs a section of longline on the two traction wheels by using a hook. The two traction wheels are driven by a motor to rotate synchronously, driving the longline Moving slowly, the crew stands between the two traction wheels to salvage the passing vertical rope. The crew manually untie or cut the vertical rope from the longline, and collect ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the harvesting of the existing artificial cultured oysters is carried out separately, the degree of mechanization is also low, and the harvesting consumes a lot of manpower and the efficiency is low
