Problems solved by technology

[0002] The aerator is a life-saving and stimulating equipment for fish and shrimp in aquaculture. The existing mechanical aerators mainly include waterwheel type, impeller type and water spray type. The existing waterwheel aerators are large Part of it is composed of multiple floating bodies, welded with angle steel to form a bracket, the floating boat is fixed under the bracket, and the main engine and bearing seat are installed on the bracket; it is also connected by thin-walled stainless steel square tubes, but the strength of the holes is greatly reduced after the stainless steel square tubes are drilled. And fracture, so the stainless steel square tube can not be too thin, because stainless steel is expensive, so the manufacturing cost is higher

Embodiment Construction

[0050] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-19 :

[0051]A waterwheel type aerator mainly includes impeller 1, floating body, main engine 3, transmission shaft 2, bearing seat 7, etc. The floating body is connected by thin-walled stainless steel square tube 6, and square tube hole 61 is formed on square tube 6 Two or more pontoons 5 are combined into floating bodies by bolts 63 through the square tube holes. There is a reinforcement plate 62 above the square tube hole 61. The two sides of the reinforcement plate are bent and wrapped around the square tube 6 sides. Bolt 63 is fixed in the groove position, and most of bolt is in the groove position of pontoon, and the side 53 width of pontoon can be reduced, and the packing volume of pontoon 5 is reduced, and groove 51 improves the load-bearing capacity of pontoon; The directly mounted motor 31 drives the horizontal output shaft 3...

Abstract

The invention belongs to an aquaculture machine and relates to a waterwheel-type aerator. The waterwheel-type aerator comprises an impeller, a floating body, a main machine, a transmission shaft and a bearing seat, wherein the floating body is connected by virtue of a thin-wall stainless steel square tube; the square tube is provided with holes through which bolts cab pass; more than two floatingboats are combined by passing the bolts through square tube holes so as to form the floating body; a reinforcing plate is arranged above the square tube holes; two sides of the floating boats are provided with grooves and the bolts are fixed in the grooves; the impeller is composed of a blade and an impeller disc; the impeller disc is provided with a retaining mechanism which is molded by injection; one end of an elastic retaining strip and the straight edge of the impeller disc are molded into a whole body by virtue of injection and the other end of the elastic retaining strip is suspended; and after the blade is assembled in place, the retraining strip is reset and the blade is prevented from being moved out.

Description

technical field [0001] The invention relates to an aerator, in particular to a water wheel aerator. Background technique [0002] The aerator is a life-saving and stimulating equipment for fish and shrimp in aquaculture. The existing mechanical aerators mainly include waterwheel type, impeller type and water spray type. The existing waterwheel aerators are large Part of it is composed of multiple floating bodies, welded with angle steel to form a bracket, the floating boat is fixed under the bracket, and the main engine and bearing seat are installed on the bracket; it is also connected by thin-walled stainless steel square tubes, but the strength of the holes is greatly reduced after the stainless steel square tubes are drilled. And fracture, so the stainless steel square tube can not be too thin, because stainless steel is expensive, so the manufacturing cost is higher. Contents of the invention [0003] The purpose of the present invention is to provide a low-cost and ...
