Crab breeding device

Abstract

A crab breeding device comprises breeding box sets, connecting mechanisms, a first driving piece and a feeding device. Each feeding box set comprises a body (77) and at least two breeding boxes (7) arranged at intervals along the periphery of the body, each breeding box (7) is provided with a feeding port (70), and the feeding ports (70) of the breeding boxes (7) are aligned one by one in the circumferential direction; the connecting mechanisms are used for connecting the breeding box sets and are suspended on a culture pond (1); the power output end of the first driving piece (8) is connected with the breeding box sets and used for driving the breeding box sets to rotate; and the feeding device (2) is arranged on the culture pond (1) and comprises a feeding part, and the feeding part can be in one-to-one correspondence with the feeding port (70) of any one of the breeding boxes in the state that the breeding boxes (7) rotate in the circumferential direction, so that feeding of each breeding box (7) is completed. Compared with the prior art, the crab breeding device has the beneficial effects that feeding can be completed only by arranging one feeding point, and water flowing can be promoted.

Description

technical field [0001] The invention belongs to the technical field of aquaculture devices, and in particular relates to a crab cultivation device. Background technique [0002] The main breeding mode of crabs is pond farming. Although the total amount is large, there are problems such as backward pond facilities, low breeding survival rate, and low added value of products, which restrict the development of the industry. Land-based monomer culture of crabs is one of the feasible methods to solve the above problems. By collecting sub-adult crabs from ponds and transferring them to separate cultures in the monomer culture system, it can not only prevent fratricide and go on the market in reverse seasons, but also produce high-quality crabs such as soft shell crabs. Value-added aquatic products. [0003] Based on this, people have developed a land-based monomer culture device for crabs, such as the patent No. ZL201110280120.8 for the invention patent "Indoor Stereo Cultivation...

AI Technical Summary

Problems solved by technology

But this patent has the following problems: 1. Although this patent only needs to use one feeding device, the feeding device needs to move back and forth to different feeding points for feeding when in use, and each culture basket in the culture pond is relatively opposite to the culture pond. It is set statically, which leads to insufficient water flow, which affects the growth of crabs; 2. The structure of the feeding device is complicated, and the general feeding device on the market cannot be applied; 3. Intertidal crabs such as blue crabs need to be dewed regularly, but The breeding system is designed for 24h immersion
