A method and equipment for mechanized feeding and harvesting of oysters on floating rafts at sea

Abstract

The invention relates to a mechanical seed dropping and harvestingdevice for marine buoyancy raft oyster culture. The bottom of a culturing raft frame is provided with buoyancy tanks which are provided with a steel frame, and the end portions of the steel frame are provided with connecting piles; the culturing raft frame is provided with a first pulley which is provided with a drawing cable, the lower portion of the drawing cable is provided with quick fasteners at intervals for hooking a main cable, branch cables are suspended on the main cable, and oysters or oyster carriers are attached to the branch cables; a truss is arranged on a loading ship, the sides of the loading ship are provided with connecting pipes matched with the culturing raft frame for fixing the culturing raft frame onto the sides of the loading ship; the direction of the main cable on the truss is perpendicular to that of a beam; the loading ship is provided with a lifting power block which is provided with a second pulley corresponding to the first pulley. The mechanical seed dropping and harvestingdevice for marine buoyancy raft oyster culture achieves rapid transportation of oyster culturing raw materials, solves the problems of labor required during dropping and harvesting of marine oyster culturing processes and can complete dropping, harvesting and transportation with assistance of only a few workers, thereby improving the efficiency.

Description

Technical field [0001] The invention relates to a method and equipment for oyster breeding and seedling harvesting, in particular to a mechanized seedling and harvesting method and equipment for oyster breeding on floating rafts at sea, belonging to the technical field of oyster breeding. Background technique [0002] Oysters are the world's largest cultured shellfish, and China is the main producer of oysters, with aquaculture production accounting for more than 82.0% of the world's total oyster production. The southern waters of Guangxi is an important area for oyster breeding. The main local breeding method is raft breeding. The seedling and harvesting during the breeding process cannot be mechanized. It is completely dependent on manual operations and the production efficiency is low. Workers work on floating rafts at sea. The working environment Dangerous and bad, high labor intensity and long time have become the main technical bottleneck restricting the development of loca...

Problems solved by technology

The southern sea area of ​​Guangxi is an important area for oyster farming. The main local farming method is raft farming. The seedling feeding and harvesting in the breeding process cannot be mechanized. It is completely manual and the production efficiency is low. Dangerous and harsh, high labor intensity and long time, has become the main technical bottleneck restricting the development of local oyster farming
