Fish pond feeding and oxygenation device in fish and vegetable symbiosis system

Abstract

The invention relates to the technical field of fish and vegetable symbiosis, and discloses a fish pond feeding and oxygenation device in a fish and vegetable symbiosis system. The fish pond feeding and oxygenation device comprises a box body, wherein an upper frame is movably mounted at the upper end of the box body, a baffle is fixedly installed at the middle upper end of the interior of the box body, a food storage shell is fixedly mounted at the middle of the baffle, and a food outlet is fixedly formed in the outer surface of the food storage shell; and a fixing block is movably mounted in the food storage shell, a tablet is fixedly mounted at the lower end of the fixing block, balance balls are fixedly mounted at two ends of the tablet, a connecting rod is movably mounted on the front surface of the fixing block, a rubber plug is movably mounted at the upper end of the connecting rod, and a breather pipe is slidably mounted on the outer surface of the rubber plug. Through cooperative use of the rubber plug and the breather pipe, the rubber plug can effectively move up and down to extrude air into the food storage shell, and the air is exhausted out along with foods through a food outlet shell, so that oxygen is increased for water, and the survival rate of fish is improved.

Description

technical field [0001] The invention relates to the technical field of fish and vegetable symbiosis, in particular to a device for adding food and oxygen to fish ponds in a fish and vegetable symbiosis system. Background technique [0002] After more than 30 years of theoretical research and practical application, the fish and vegetable symbiosis system has experienced the early difficult exploration and the mid-term evolution of various systems and processes, forming a relatively complete fish and vegetable symbiosis engineering system. The fish and vegetable symbiosis system evolved from the simple concept of natural circulation, and the technology used at the beginning was relatively simple, using the method of direct contact and coexistence of fish and vegetables, but as time went by, the method has also been greatly improved. [0003] At present, in the existing technology, fish often eat the root system of vegetables exposed on the water surface, resulting in the lack ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing technology, fish often eat the root system of vegetables exposed on the water surface, resulting in the lack of vegetable root system and a large number of deaths. In addition, in the process of feeding fish food to fish, some uneaten fish food It may be soaked in water for a long time, the soaking will become soft and loose, resulting in turbid water quality, which is not suitable for the growth of fish. In severe cases, it may cause a large number of fish to die, which brings unnecessary losses to the farmer's economy.
