Fish and shrimp cage quick replacing device

Abstract

The invention relates to a fish and shrimp cage quick replacing device and belongs to the technical field of fish and shrimp pool change. The device is characterized by comprising a single-head conveying pipe (8) and a fish and shrimp transfer conveying channel formed by a multi-head conveying pipe (17), wherein upper portions of multiple vertical pipes are communicated with an upper portion of the single-head conveying pipe (8) through a transversely-arranged connection pipe, an upper portion of the multi-head conveying pipe (17) is provided with a support (14), the support (14) is connectedwith a suspension rack (12) above the support (14) through a steering device, the single-head conveying pipe (8) and the multi-head conveying pipe (17) are water conveying pipes, and the water conveying pipes include multiple coaxially-mounted spiral water conveying rings. The device is advantaged in that the multiple spiral water conveying rings are employed to form the spiral water direction, the suction force for the fish and shrimp can be formed, the conveying pipes internally have no guide and stirring parts, when the fish and shrimp are abstracted, contact damage to the fish and shrimp is avoided, high-quality conveying of sea products is achieved, and the fish and shrimp are fully guaranteed to be fresh and vital.

Description

technical field [0001] A quick replacement device for fish and shrimp cages belongs to the technical field of fish and shrimp dumping. Background technique [0002] At present, the problem of transfer of factory seedlings and seedlings: During the breeding of fish seedlings, the dirt on the walls and bottom of the workshop should be cleaned regularly, and the seedlings need to be transferred. Spread the seedlings in the pool. In the process of moving the pond, due to the small size of the fry and the intolerant of dry dew, manual pouring into the pond is easy to cause mechanical damage to the fry, which can easily lead to bacterial infection, and it is time-consuming and laborious; the rate of damage to the larvae of crab fry is higher. , can cause a single pool to die. 2. The problem of moving juvenile fish in deep-water cage culture: During the process of deep-water cage culture, it is necessary to clean and replace the net clothes regularly. The transfer of juvenile fis...

AI Technical Summary

Problems solved by technology

In the process of moving ponds, due to the small size of fish fry and their intolerance to dry dew, manual pouring of the pond is likely to cause mechanical damage to the fry, which can easily lead to bacterial infection, and is time-consuming and laborious; the damage rate of crab fry larvae is higher. , can cause a single pool to fail

2. The problem of moving juvenile fish in deep-water cage culture: In the process of deep-water cage culture, it is necessary to regularly clean and replace the net clothes. Transferring juvenile fish may easily cause fish scales to fall off and cause damage. The labor intensity is high and the risk is high.
