The invention discloses a device for extracting live fish before processing. The device is provided with three water ponds, wherein one water pond is a temporary rearing pond, one water pond is a fishpond for fish which do not meet a specification, and one water pond is a temporary water storage pond. A large number of fish-containing water columns are sucked from the temporary rearing pond through negative pressure; then sorting is carried out through a sorting platform, live fish meeting to the specification are conveyed to a processing line, and live fish which do not meet the specification are placed in the fish pond for fish which do not meet a specification; and residual water after sorting is placed into the temporary water storage tank, so that circulating water does not directlyenter the temporary rearing pond during working, and the circulating water is temporarily stored in the temporary water storage tank. When the fish is sucked, a large number of fish can be gradually gathered to a negative-pressure water suction opening along with the reduction of the liquid level in the temporary rearing pond, and manual small-batch suction is not needed, so that the working timeof a negative-pressure motor is shortened, fish sucking efficiency is greatly improved, and meanwhile, the problem that a common temporary rearing pond cannot suck the fish completely is solved.
Description
technical field [0001] The invention relates to the technical field of freshwater fish processing, in particular to a live fish extraction device before processing. Background technique [0002] At present, in the field of freshwater fish processing, the pre-processing extraction process of live fish is mainly to extract live fish from the holding pond and enter the processing line before the primary automatic processing (such as descaling) of freshwater fish such as grass carp and silver carp. At present, there are two main extraction methods for domestic freshwater fish before processing: one is the manual fishing method, where the live fish is temporarily raised in an ordinary rectangular pool, and the fish is sucked into the processing line through a pipe extending into the pool. The manual fishing method requires Manually hold the pipe to suck the fish, the fish run around, and the person cannot suck the fish without changing the position of the pipe, so the efficiency ...
