Fancy carp automatic sorting system

Abstract

The invention discloses a fancy carp automatic sorting system which comprises a circular rail and a fish cabin, wherein the circular rail is arranged on the water level of a fishpond, and the fish cabin is provided with an upper opening and arranged on the circular rail through rollers. The fish cabin is connected with a conveying chain arranged on the circular rail, the conveying chain is drivenby power, a bottom plate of the fish cabin is of a downward overturning door structure, opening and closing of the bottom plate are driven by a power mechanism, a plurality of fish sorting net cages are arranged in the fishpond along the lower portion of the circular rail, position detection sensors are arranged on the circular rail and positioned at the fish sorting net cages, a shooting device and a fish storage tank are arranged above the circular rail, the shooting device is used for shooting fish images in the fish cabin, a fish outlet is formed in the bottom of the fish storage tank andcommunicated with a fabric cylinder, and a lower opening of the fabric cylinder is positioned above the circular rail. The system has the advantages that acquired images and fancy carp type characteristics can be compared by the aid of digital image techniques, and fancy carps are placed into the fish sorting net cages in a classified manner, so that the fancy carps are automatically classified.

Description

technical field [0001] The invention relates to the field of aquatic ornamental fish cultivation, in particular to an automatic sorting system for koi. Background technique [0002] Koi belongs to Cyprinidae biologically and is a high-end ornamental fish that is popular in the world today. Koi are physically fit, colorful, changeable in pattern, and majestic in swimming. They have high ornamental and breeding value, and are known as "living gems in water" and "swimming artworks". Its body length can reach 1-1.5 meters, and its colors are mainly red, yellow, white, orange, black, etc., with ever-changing patterns. Koi are mild in nature, like to swim in groups, and have strong adaptability to water temperature. They can live in a water temperature environment of 5-30°C. They are omnivorous and easy to raise. The breeding volume of koi in Henan alone exceeds 20,000 mu, and the output exceeds 40 million catties, which is a huge amount of breeding. [0003] The breed of koi i...

Problems solved by technology

However, there are a lot of fish fry at this stage that have not yet turned color, which is very easy to be misselected, and the white fry collection container and the black fry collection container make the fry enter the collection container by the negative pressure produced, so it must produce the following disadvantages: 1. Due to the negative pressure in the collection container, the fry will die due to lack of oxygen in the water, thus losing the meaning of selection

2. Due to the limitation of providing negative pressure to the collection container, the collection container cannot be large, so its fish load is small, and the fish in the collection container needs to be cleaned frequently during use

3. Due to the selection of koi at the "Wuzi" stage for screening, more than 50% of the screened black seedlings will still have color variation in the subsequent breeding stage, and the screening quality is low
