Prawn culture device

Abstract

The invention relates to a prawn culture device which comprises a net cage, a lifting mechanism and a feeding mechanism. The feeding mechanism comprises a sleeve, a filter screen box and a connectingassembly, and the lifting mechanism comprises a driving assembly and a lifting assembly. The prawn culture device realizes fixed-point feeding of a main body through the feeding mechanism, and the conditions that due to overlarge sea waves, baits are scattered, and waste of the baits is caused are avoided; the movement of the filter screen box is realized through the lifting mechanism, so that thefishing of the main body is realized, the selling of the main body is realized, the workload during fishing is reduced, and the fishing cost is reduced; meanwhile, the rotation of the filter screen box can also be realized through the operation of a motor, and impurities on the filter screen box are thrown out, so that the interior of the filter screen box is always kept in a clean state, and thefeeding environment of the main body is improved; and the filter screen box is more stable during rotation through a positioning unit, stress on a supporting rod is reduced, the supporting rod can better slide in a rectangular groove, jamming is prevented, and the service life is prolonged.

Description

technical field [0001] In particular, the invention relates to a culture device for prawns. Background technique [0002] Prawns, the scientific name is Oriental prawns, also known as Chinese prawns, monodon prawns, Arthropoda, Crustacea, Decapods, Penaeidae, Penaeus, and Penaeus are large individuals, commonly known as prawns, and prawns have to go through dozens of times in the growth process. The molting of the skin, every time the skin is molted, it will get a larger growth. The molting is an important symbol of the growth of prawns, which is directly affected by the external environmental conditions. The prawns are named because fishermen used to calculate the sales of "one pair" products in history. Distributed in coastal shallow waters where the seawater temperature is above 20°C, the prawns belong to the phylum Arthropoda, the subphylum Branchia, the class Crustacea, the subclass Mollusca, the order Decapod, the suborder Swimming, the family Penaeidae, and the genus ...

Problems solved by technology

[0003] At present, prawns are cultured in fish boxes in deep sea culture, and the feeding method is generally by direct splashing. This method has many disadvantages, and it is easy to cause waste of feed and cannot be fed at fixed points. When it is necessary to feed prawns When a small amount of capture is sold, it is necessary to hoist the entire net cage and then capture, which is costly, heavy workload, and troublesome
