Ventilation device for pond fish culture

Abstract

The invention belongs to the technical field of fish culture, and particularly relates to a pond fish culture ventilation device which comprises a main machine body, the main machine body is hemispherical, a fan cavity is formed in the main machine body, and a supporting rotating shaft is rotationally arranged between the front wall and the rear wall in the fan cavity. According to the device, through rotation of a supporting rotating plate, a rotating plate makes contact with a contact plate to move and generate vibration force, at the moment, fish feed stored in a storage cavity swings outwards under the action of centrifugal force, and then fishes are guided to swim on the outer side of the device; the fish is protected from approaching the main machine body to influence the work of the main machine body, meanwhile, the safety of the fish cultured in the pond is protected, the fish is protected from swimming into the stirring cavity through the protection net moving downwards, and the safety and survival of the fish cultured in the pond are further protected.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a ventilation device for fish farming in ponds. Background technique [0002] In the process of fish farming, because some ornamental fish are more precious, we need to be very careful in the process of pond ventilation to prevent fish from dying, and the general pond ventilation device simply fixes the ventilation device on the pond The edge, and then complete the work through long-term and fixed-point ventilation. The efficiency of the internal ventilation of the pond as a whole is not high. At the same time, the supplement of oxygen content in the gas inside the pond cannot be uniform, and it has a protective effect on fish. not tall. Contents of the invention [0003] The object of the present invention is to provide a kind of ventilation device for pond fish breeding, which is used to overcome the above-mentioned defects in the prior art. [0004] A ventilation devi...
