AI Technical Summary

⚠Technical Problem

Existing aquaculture fishing equipment has a low degree of automation and is difficult to adapt to complex pond bottom terrain, resulting in fish escaping and low fishing efficiency. In addition, traditional nets cannot be accurately positioned or prevented from shaking, which affects the fishing effect.

⚗Method used

The fishing device, which uses a combination of track bars, drive components, and moving tow plates, along with a graded fishing net, a magnetic shaping frame, and flexible silicone skirts, utilizes the impact force of water flow to automatically deploy and retract the net. Combined with flexible LED light-attracting strips and anti-jump protection components, it improves fishing efficiency and automation.

🎯Benefits of technology

It realizes the automated reciprocating motion of the fishing device, reduces the intensity of manual labor, improves the fishing effect, prevents fish from escaping, reduces stress response, and improves fishing efficiency and fish survival rate.

Abstract

This invention relates to the field of aquaculture technology, and in particular to a bass farming and harvesting equipment. Its structure includes a farming pond located on a embankment, with track bars installed on both sides of the pond. A drive assembly is installed at one end of each track bar, and a harvesting device is mounted on the track bars. A guide structure is symmetrically installed on the inner wall of the farming pond. This equipment solves the problems of low harvesting efficiency, significant fish damage, and easy escape from the bottom and sides during harvesting in traditional methods. It utilizes a multi-segment silicone skirt at the bottom of the net to adaptively conform to the pond bottom, and an arc-shaped protective net with a scratch-resistant fleece lining at the top to prevent fish from jumping and getting injured. The primary and secondary nets are connected by a one-way escape-proof channel, and the difference in mesh size allows for automatic grading of fish by size.
