Reducer-free water-sucking aerator

Abstract

The invention discloses a reducer-free water-sucking aerator which comprises an electric motor, a drive stand, a water-sucking impeller, supporting rods and floating balls, wherein the upper end of the drive stand is connected to the electric motor, the lower end is connected to a water segregator, the water-sucking impeller is disposed under the water segregator, a spindle of the water-sucking impeller passes through the water segregator to be connected to a spindle of the electric motor, the drive stand is supported by the supporting rods and the floating ball, the water segregator is shaped like an inverted cone, the three supporting rods are disposed uniformly around the drive stand, the floating ball is disposed respectively at the other end of the supporting rod, an electric motor waterproof cover is disposed on the electric motor, water-sucking covers are disposed on the water segregator and the water-sucking impeller, the upper and lower ends of the water-sucking cover are opened, the water-sucking cover is cylindrical, the upper end is connected on the drive stand by four connecting rods, a guard net is disposed on the lower end, and the electric motor directly drives the water-sucking impeller with small blades to suck water directly, so that kinetic energy generated by the electric motor can be utilized effectively, lubricating oil needs not to be filled periodically, fish pond pollution caused by oil leakage can be prevented effectively, and repair becomes convenient.

Description

technical field [0001] The invention relates to aquaculture equipment, in particular to a water-absorbing aerator without a reducer. Background technique [0002] The fish pond aerator is the necessary breeding equipment to improve the water quality environment and ensure high and stable production. The use of fish pond aeration machine can increase the dissolved oxygen in the water and prevent fish from floating and dying due to lack of oxygen. It can effectively improve the living conditions of fish, increase the breeding density, and accelerate the growth of fish. The aerator is used to increase the amount of dissolved oxygen. An effective method, in addition to increasing oxygen, can also promote the circulation of water, and can prevent the temperature stratification, chemical stratification and oxygen stratification of the water body. The aerator is driven by a power source such as an electric motor or a diesel engine to make the air The "oxygen" in the water is quick...

AI Technical Summary

Problems solved by technology

At present, the general power source of the impeller type aerator drives the rotation of the impeller through the transmission device and the reducer, which needs to be regularly filled with lubricating oil for the transmission device and the reducer, and the maintenance is relatively difficult
