Multifunctional impeller aerator for aquaculture

Abstract

The invention provides a multifunctional impeller aerator for aquaculture. The multifunctional impeller aerator for aquaculture comprises a boss, an oil tank, a blocking block, a pull rod, a scale rod, a floating block, a spring, a reflector, a drawstring and a copper bell, wherein the boss is arranged at the annular side surface of a motor, the oil tank is mounted on the right side of the upper end surface of the boss, and the blocking block is assembled at the inner bottom of the oil tank; the lower end of the pull rod is fixed at the middle of the upper end surface of the blocking block, the scale rod is assembled at the upper end of the oil tank, and the lower end of the scale rod runs through the oil tank and is connected with the floating block; the blocking block is disposed insidethe oil tank; and through the design, the addition amount of gear oil can be controlled conveniently, the spring is mounted on the upper end surface of the floating block, the reflector is assembled on the upper end of the spring, and the drawstring is mounted on the outer surface of the reflector; and the copper bell is assembled on the lower end of the drawstring through screws. Through the design, the function of bird repelling can be achieved, and the aerator has simple operation, convenient control on the addition amount of the gear oil, a good bird repellent effect and high practicability.

Description

technical field [0001] The invention is a multifunctional impeller type aerator for aquaculture, which belongs to the technical field of aerators. Background technique [0002] In the prior art, there are still many deficiencies in the impeller-type aerators for aquaculture. The lubrication method uses manual pouring of gear oil, which is easy to cause waste of gear oil. At the same time, the amount of addition cannot be controlled, and the practicability is poor. Function, cause the birds to climb on the connecting rod and the floating block, the excrement produced by it is easy to pollute the floating block, so a kind of multifunctional impeller type aerator for aquaculture is needed to solve the above problems. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a multifunctional impeller-type aerator for aquaculture to solve the problems raised in the above background technology. The present...
