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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] see Figure 1-3 , Standard modular sea farming raft frame: The central breeding area of ​​a single farming raft frame module is 6*6m, with a frame structure around it, buoys are installed at the four corners of the bottom, and a walkway is laid above it as a working channel. The raft frame modules can be rigidly or flexibly connected according to the conditions of the aquaculture sea area, and several groups are arranged in a line, or two rows of raft frame modules are arranged side by side and then several groups are arranged horizontally.

[0032] continue to see Figure 1-3 A number of corresponding locks are installed on the left and right inner walls of the raft farming area, which are used to fasten each main breeding rope, and a quick connection device is installed at the corresponding position of the front walkway of the raft fr...

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 seedling-feeding and harvesting method and equipment for oyster culture, in particular to a mechanized seedling-feeding and harvesting method and equipment for oyster culture on floating rafts at sea, and belongs to the technical field of oyster culture. Background technique [0002] Oysters are the largest cultured shellfish in the world. China is the main producer of oysters, and its aquaculture production accounts for more than 82.0% of the world's total oyster production. 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 have become the main technical bottleneck restricting the development of local oyster farming. Contents of the invention [0003] Th...
