An eel sorter

Abstract

The invention discloses an eel classifier. The eel classifier comprises a plurality of multiple fishponds arranged in row, and eels with the gradual-increasing volumes or eels with the gradual-decreasing volumes are sequentially fed through all the fishponds from left to right; the eel classifier comprises a grading pipe, the grading pipe comprises sorting pipes put into all the fishponds; the adjacent ends of the upper sorting pipes and the lower sorting pipes are communicated through sorting connecting pipes; grade filtering nets are arranged at eel feeding ends of all the sorting connecting pipes, and upper sorting openings and lower sorting openings are formed in the grade filtering nets; longitudinal partition plates are arranged in all the sorting connecting pipes, the sorting connecting pipes are divided by the longitudinal partition plates into upper sorting pipes communicated with the upper sorting openings and lower sorting pipes communicated with the lower sorting openings, eel outlets communicated with the upper fishponds or the lower fishponds are formed in the upper sorting pipes, and the lower sorting pipes are communicated with the lower sorting pipes or the upper sorting pipes. According to the eel classifier, habits of burrowing and drilling of the eels are used, the eels are guided to be automatically sorted through artificial caves, namely, one-way eel feeding openings, the sorting effect is good, and occurrence of the phenomenon that large eels eat small eels is avoided.

Description

Technical field: [0001] The invention mainly relates to an eel sorter. Background technique: [0002] The nutritional value and medicinal value of rice field eel are very high, and it is known as a high-grade tonic. Due to the short supply in the market, the price of rice field eels has remained high. The reason why the market is in short supply is that so far, rice field eels cannot be cultivated on a large scale, and the reason why they cannot be cultivated on a large scale is that rice field eels have the habit of cannibalism of the big and the small. Therefore, when rice field eels are raised in large water surfaces, the seedlings bred by the rice field eels are basically eaten by themselves or other rice field eels. Even if eel seedlings of the same specification are put in, due to the difference in growth rate, after a period of time, there will still be a serious phenomenon of eating eel. Therefore, during the breeding process of rice field eels, they must be sorte...

Problems solved by technology

However, rice field eels have the habit of digging and drilling holes, so it is impossible to sort rice field eels in large-scale farming, which leads to extremely low production of rice field eels in large-scale farming.

However, the current cage culture can be sorted, but the workload of daily management work such as feeding and sorting the cage culture of rice field eels is very large, which is the main reason that limits the large-scale cultivation of rice field eels.
