Culture and feeding device for fish

Abstract

The invention discloses a culture and feeding device for fish. The culture and feeding device for fish comprises a feeding box, a feeding hole is formed in a side face of a bottom part of the feeding box, a part, located above the feeding hole, of the side face of the bottom part of the feeding box penetrates through and is fixedly connected with a pushing device, the bottom part of the feeding box is rotationally connected with a rotating shell through a bearing, a bottom part of an inner wall of the rotating shell is fixedly connected with a clockwork spring, one side, away from the rotating shell, of the clockwork spring is fixedly connected with the bottom part of the feeding box, a communicating hole matched with the feeding hole is formed in an outer side of the rotating shell, and a resistance device is arranged on a side face of a bottom part of the rotating shell. The invention relates to the technical field of fish culture. The culture and feeding device for fish can expand a feeding range, avoids scramble injuries caused by fish school gathering, can automatically control opening of the feeding hole, is relatively convenient to use, conveniently and freely controls a pushing force of the pushing device, has relatively good adjustability and can conveniently and freely control a feeding speed of the feeding box.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a feeding device for fish farming. Background technique [0002] The breeding, rearing and stocking of fish, fish farming, also known as aquaculture, pisciculture and pisciculture, is important in maintaining food supplies, angling and expanding fishing areas, through which many species been successfully introduced into new regions. [0003] At present, when the fish breeding technology center adds fish food to the water, it usually uses manual direct sowing, which has low spreading efficiency and high labor consumption, and it is not convenient to carry when spreading liquid fish food, and the spreading range is small, which may easily lead to fish clusters Scrambling produces damage. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a fish breeding and feeding device, w...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fish breeding and feeding device, which solves the problem that the current fish breeding technology center usually uses manual direct spreading when adding fish food to the water, the spreading efficiency is low, and the manual consumption is relatively large. In addition, it is not convenient to carry when spreading liquid fish food, and the spreading range is small, which will easily lead to the problem of fish gathering and scrambling to cause damage
