A feeding machine for artificially cultured large yellow croaker

Abstract

The invention discloses a feeding machine for artificially breeding large yellow croakers. The purpose is to provide the feeding machine which not only facilitates feeding of the large yellow croakers, but also reduces bait waste and effectively solves the problem that after uneaten baits deposit on the seabed, breeding water quality is affected. The feeding machine comprises a supporting frame, vertical guide rods and a floating feeding device, wherein the vertical guide rods are arranged on the supporting frame. Limit stops and vertical guide sleeves are arranged on the vertical guide rods, wherein the vertical guide sleeve can slide. The floating feeding device comprises a floating feeding bin, feeding adjusting spacer sleeves, a bait pressing-out device and a synchronized cutting device. The floating feeding bin comprises a floating feeding hopper and multiple vertical discharging tubes arranged below the floating feeding hopper, wherein the floating feeding hopper is fixed to the vertical guide sleeves. All the feeding adjusting spacer sleeves are arranged under all the vertical discharging tubes in a one-to-one correspondence mode. Prestress compression springs are arranged at the positions, located below the vertical guide sleeves, of the vertical guide rods. Multiple feeding through holes are formed in the side faces of the vertical discharging tubes.

Description

technical field [0001] The invention relates to a bait feeding device for cage cultured aquatic products, in particular to a feeder for artificially cultured large yellow croaker for cage cultured large yellow croaker. Background technique [0002] Large yellow croaker is a carnivorous fish with a high demand for protein; the feed for large yellow croaker in the growing stage is generally fish and shrimp (for example, frozen mackerel and ginseng fish), supplemented with powdered compound feed, which is fed after processing . There are usually two methods of processing large yellow croaker bait: one is to cut the fish (mackerel and ginseng fish) into palatable fish pieces with a knife or a meat cutter, and then put them into the net cage; this method is easy to process and is not easy to collapse in water. It is inconvenient to add additives, and the nutrition is relatively simple. The second is to grind the fish and shrimp into minced meat, and mix it with powdered compoun...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of feeding large yellow croaker croakers in net bags in the prior art, and cause waste of bait, and after the uneaten bait is deposited on the seabed, it will also affect the quality of breeding water and destroy the marine ecological environment to provide a method for artificially breeding large yellow croakers that is not only beneficial for large yellow croakers to eat, but also can reduce bait waste, save costs, and effectively solve the problems of affecting the water quality of aquaculture and destroying the marine ecological environment after the uneaten bait is deposited on the seabed. feeder
