Automatic feeding and aerating device for pound

Abstract

The invention relates to cultivation of fish, in particular to an automatic feeding and aerating device for a pound. The device comprises a supporting seat, an electric motor, an epicyclic gearbox, revolving arms fixed with the epicyclic gearbox together and extended towards both sides and impeller wheels respectively arranged at the remote ends of the revolving arms, and is characterized in that the epicyclic gearbox divides the rotation of the electric motor into two paths of output, wherein one path of output drives the revolving arms so as to realize that the impeller wheels revolve around a center rod, and the other path of output drives the impeller wheels to rotate axially through a flexible shaft so as to realize aerating. In the aerating device, the revolution of the impeller wheels does not depend on the axial rotation of the impeller wheels; and therefore, the impeller wheels can be screw impeller wheels, so that the rotation direction of the impeller wheels is changed, water on the surface of the pound can be conveyed underwater, and water at the lower part of the pound can be conveyed towards the surface so as to increase the dissolved oxygen in the pound.

Description

technical field [0001] The invention relates to fish cultivation, in particular to a fish feeding and aeration device. Background technique [0002] The level of dissolved oxygen in the pond has a direct impact on the growth and survival of fish. Under high dissolved oxygen, fish eat vigorously, have high digestion, fast growth, high feed efficiency, and fast oxidation of organic matter, which can promote material Circulates and eliminates some toxic biological metabolites. Oxygenation in fish ponds is an important aquaculture method in the field of aquaculture to ensure the safe growth of fish, shrimp and other aquatic products, prevent weed damage, and increase production. At present, there are various types of aerators used by aquaculture enterprises, such as waterwheel type, spray type, biological rotary drum aerator, and blast gas transmission. [0003] The utility model patent with the authorized notification number CN86206535U discloses "an impeller type aerator for...

AI Technical Summary

Problems solved by technology

But above-mentioned patent scheme still has the following deficiencies: 1, utilize the reaction moment produced respectively at the end of two transmission arms when two impellers rotate on their own to drive two impellers to revolve around the center of two transmission arms, but when the rotating speed of two impellers is slower or When the two transmission arms are relatively short, the reaction moment generated is relatively small, and the revolution is difficult to realize, especially when there are floating aquatic plants in the fish pond, the revolution is even more difficult to realize, or even impossible; 2. Use the reverse rotation of the motor to stop the revolution, and the impeller can only use straight blades, so the upper and lower water in the fish pond cannot flow and exchange, and the oxygenation efficiency is obviously damaged; 3. Only oxygenation can be achieved, in order to realize fish feeding It is still necessary to arrange a fixed feeding machine in the fish pond, because the 360-degree mobile feeding machine needs a large rotation space, and there is mutual interference between the two
