Fish feed feeding device for livestock breeding

Abstract

The invention relates to the technical field of livestock breeding, and discloses a fish feed feeding device for livestock breeding. The fish feed feeding device for livestock breeding comprises a mixing box. The left side of the top of the mixing box communicates with a feeding hopper, the top of the mixing box is fixedly connected with a first motor, an output shaft of the first motor is fixedlyconnected with a rotary rod through a coupler, a first bearing is embedded into the top of the mixing box, the inner ring of the first bearing and the surface of the rotary rod are fixedly sleeved, the surface of the rotary rod is fixedly connected with stirring blades, and the portion, located below the stirring blades, in the mixing box is fixedly connected with an annular fixing plate. By means of a screening plate vibrating up and down, fish feed is screened, the situation that particles of the fish feed are large is avoided, meanwhile, the screened fish feed is thrown out and cast into afish pond by a feeding box through centrifugal force, and the situation that as the fish feed is cast in an excessively-concentrated manner, fishes collide with one another and are hurt is avoided.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a fish feed feeding device for animal husbandry. Background technique [0002] Fish feed, as the name suggests, is feed for fish. Its main components are protein, fat, vitamins and minerals. Protein is an important nutrient for the survival of fish and shrimp, and an important component of the cells, tissues and organs of the body. The normal growth of fish requires protein in sufficient quantity, easy to digest and absorb, and suitable ratio of various amino acids in the feed. When the intake of protein is insufficient for fish, the growth will be slow, the immunity of the body will be reduced, and the protein with appropriate ratio of various amino acids. When the protein intake of fish is insufficient, the growth is slow, the immunity of the body is reduced, the tissue renewal is slow, the wound healing is poor, and the disease is easy. [0003] For the feeding an...

Problems solved by technology

[0004] However, due to the different growth periods of the fish cultured in the fish pond, the size requirements for the fish feed are different. When there are young fry in the fish pond, the fish feed with larger particles makes the fry unable to eat directly, and the larger fish Fish feed with smaller particles can be eaten, so a fish feed feeding and throwing device with screening function is needed. At the same time, the existing fish feed feeding and throwing devices are often in a fixed position when throwing, so that fish schools collide with each other. Prey on each other, causing some fish in the school to be injured
