Embodiment Construction

[0051] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-19 :

[0052] An impeller with a backstop mechanism for the impeller disc, mainly composed of blades and impeller discs, see Figure 1-4 , The blade mounting part 131 can be provided with a C-shaped chute 121 to cooperate with the T-shaped guide rail 111 on the impeller disc; the impeller disc 11 can have a stop-back mechanism that is injection molded together. The impeller backstop mechanism is: the impeller disc 11 is a polygonal window-shaped structure, and each straight side of the window is connected to the center shaft hole 114 by spokes 118, and each straight side is provided with a T-shaped guide rail 111, T-shaped There is a stopper 117 at the rear end of the guide rail, and there is an elastic stop strip 112 at the front end of the T-shaped guide rail. One end of the elastic stop strip is injection-molded with the straight ed...

Abstract

The invention belongs to an aquacultural machine and relates to an impeller with a retaining mechanism on an impeller disk. The impeller is composed of a blade and the impeller disk; the retraining mechanism formed in an integral injecting way together is arranged on the impeller disk; one end of an elastic retaining strip and the straight edge of the impeller disk are injected into a whole; the other end of the elastic retaining strip is suspended; the retraining strip resets and prevents the blade from retreating after the blade is assembled at a proper position; a water-wheel aerator with a retaining mechanism impeller comprises a floating body, a main machine, a transmission shaft and a bearing block; the floating body is connected by a thin-wall stainless steel square tube; a hole passing through bolts is arranged on the square tube; more than two floating boats are combined into the floating body through square tube holes via the bolts; a reinforcing plate is arranged above the square tube holes; grooves are arranged at the two sides of the floating boats, and the bolts are fixed inside the grooves.

Description

technical field [0001] The invention relates to an aerator, in particular to an impeller with a backstop mechanism on the impeller disk and a waterwheel type aerator with the backstop mechanism impeller. Background technique [0002] The aerator is a life-saving and stimulating equipment for fish and shrimp in aquaculture. The existing mechanical aerators mainly include three types: waterwheel type, impeller type and water spray type. The existing waterwheel type aerator The impellers are composed of blades and impeller discs, and the blades and impeller discs must be fixed by bolts or bolts, which makes assembly troublesome, such as Chinese patents: 93225475.6, 03203529.2, 200810004442.8. Most of the existing water wheel aerators are composed of multiple floating bodies, which are welded with angle steel to form a bracket. After the hole, the strength of the hole is greatly reduced and broken, so the stainless steel square tube should not be too thin, because the stainless...
