Fish domestication device

Abstract

The invention provides a fish domestication device, and belongs to the field of cultivation. The fish domestication device comprises an installing rod, wherein the lower end of the installing rod is fixedly connected with the bottom of a pond; the upper end of the installing rod is fixedly connected with a rotating motor; a cylindrical processing tube is fixedly connected onto a motor rotating shaft of the rotating motor; a plurality of material throwing holes are formed in the outer wall of the processing tube; the domestication device also comprises a linear motor arranged above the pond; a motor shaft of the linear motor is in vertical arrangement; the end part of the lower end of the linear motor is fixedly connected with a grinding block; the grinding block can enter the processing tube; a material blocking device is fixedly connected onto the linear motor; the material blocking device comprises fixing frames which are in a 7 shape and are respectively fixed at two sides of the linear motor; one end of each fixing frame is fixedly connected onto the linear motor; the other ends of the two fixing frames are in downward arrangement; a blocking block is fixedly connected between the end parts of the other ends of the two fixing frames; the middle part of the blocking block is provided with an extending-in hole; a flaring-shaped blocking plate is fixedly connected onto the outer wall of the blocking block, and covers the processing tube. The fish domestication device has the advantages that the structure design is ingenious; the material spreading is uniform; the domestication effect is good.

Description

technical field [0001] The invention belongs to the field of breeding and relates to a fish domestication device. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns and tiger prawns. Arthropoda, Crustacea, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. During the growth process, prawns have to go through dozens of molts, and every time they molt, they will get a larger growth; molting is an important symbol of the growth of prawns, which is directly affected by the external environmental conditions. Prawns get their name from the historical custom of fishermen to sell them as a “pair” product. Distributed in coastal shallow waters where the seawater temperature is above 20°C. Prawns belong to Arthropoda, branchial subphylum, crustacea, soft armor subclass, decapod order, swimming suborder, prawn family, and genus prawns. Chinese prawns are one of the main species of the genus Pena...
