Waterwheel type aerator

Abstract

A water wheel type oxygen enriching machine for culturing fish or others in water is composed of more than two floating boats, motor and its speed variator, rotary shaft, blade wheels installed to said rotary shaft, and the bearings and their holders, which are made of rubber and consist of two halves for easy installation.

Description

technical field [0001] The invention relates to an aerator, which is mainly used for aquaculture and belongs to fishery machinery. Background technique [0002] In aquaculture such as fish and shrimp, because oxygen-rich water is needed, it is often necessary to configure an aerator to increase oxygen. There are many types of aerators currently used in aquaculture, and one of them is called "waterwheel aerator". Connected, the motor is installed on the bracket, and the motor drives the blades of the waterwheel after the speed is changed. The blades of the waterwheel continuously set off water splashes during the rotation, and fall in the air to bring in oxygen. There are major defects in the prior art as follows: one, the connection structure between the bearing block and the bearing clip for installing the waterwheel blade rotating shaft is to be shaped on an elastic clamping grab (draw hook) on the half-opened bearing seat, and to be shaped on the b...

Problems solved by technology

There are major defects in the prior art as follows: one, the connection structure between the bearing block and the bearing clip for installing the waterwheel blade rotating shaft is to be shaped on an elastic clamping grab (draw hook) on the half-opened bearing seat, and to be shaped on the bottom of the bearing clip With the matched mouth, when the two are connected and installed, the bearing clip is pressed down from the upper part, so that the bearing clip mouth is connected with the hook of the bearing seat. This kind of connection is not mandatory, so the connection reliability is poor, and it is easy to come out by itself.

The other type is to use a slot in the ring of the closed bearing seat, and a rib on the outer wall of the bearing clamp. The rib matches the slot. When installing, the bearing clamp must be wrapped first, which is very inconvenient to install.

The second is that a bracket needs to be installed on the pontoon, and the motor and water wheel parts are installed on the bracket, so there are many accessories, troublesome installation, poor firmness and low bearing capacity

Third, the side of the floating hull is flat, with low mechanical strength and poor rigidity
