Automatic fish suction screening machine for artificial breeding and seed selection of pseudobagrus truncatus

Abstract

The invention relates to the technical field of pseudobagrus truncatus breeding, in particular to an automatic fish suction screening machine for artificial breeding and seed selection of pseudobagrustruncatus. The machine comprises a first jet mechanism, a venturi tube, a fish storage box, a fish screening mechanism, a second jet mechanism, a counting mechanism and a weighing mechanism, the first jet mechanism is installed on a rack, the input end of the first jet mechanism extends into a fishpond in the working state, and the output end of the first jet mechanism communicates with the liquid inlet end of the venturi tube; the liquid inlet end of the venturi tube is communicated with the liquid outlet end of the first jet mechanism, and the fish inlet end extends into the fishpond in a working state; the fish inlet end of the fish storage box is connected with the fish outlet end of the venturi tube; the fish screening mechanism is mounted at one side of the fish storage box, and thefish outlet end extends into the fishpond in a working state; the second jet mechanism is mounted on the rack, the input end of the second jet mechanism extends into the fishpond in a working state,and the output end communicates with the liquid inlet end of the fish storage box; the fish inlet end of the counting mechanism is communicated with the fish outlet end of the fish storage box; the fish inlet end of the weighing mechanism is communicated with the fish outlet end of the counting mechanism; and the scheme is safe and efficient, and the labor cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of cut-tailed fish breeding, in particular to an automatic fish-suction and screening machine for artificial breeding and selection of cut-tailed fish. Background technique [0002] Scutellaria is a freshwater fish, a bottom fish that lives in rivers. Individuals are small, up to about 200 mm. Distributed in the Yangtze River system. The weight is tens of grams, and the age of sexual maturity is 2 to 3 years old. It is a common small economic fish in the local area. Distributed in the Yangtze River system to the Minjiang River. Its meat is tender and delicious, and it is another famous and high-quality fish with development potential after the yellow catfish, long-snout catfish, and Ussuri catfish. In recent years, due to the construction of water conservancy projects in the upper reaches of the Yangtze River, water pollution, and perennial overfishing, the amount of wild resources has declined sharply....

Problems solved by technology

In the prior art, manual operation is generally used, which is inefficient and has high labor costs. Commonly used fish suction pumps are easy to cause damage to fish. It is necessary to provide a safer and more efficient screening equipment.
