Example Embodiment

[0047] The present invention is further described below with specific examples, see Figure 1-26 :

[0048] An impeller type aerator, including a motor 27, a reduction box, an impeller, a support rod 21, and a floating body 19. The motor 27 is vertically installed on the reduction box, and the decelerated output shaft 10 extends downward, and the end has a flange 44 Connected to the fixed seat 33 of the impeller, there are three basically uniformly distributed connecting positions 25 on the outside of the reduction gearbox. The support rod 21 is fixed on the connecting position 25. The support rod 21 is composed of a steel pipe, a connecting seat 47, a fixed ring 20, and a fixed ring 46. The connecting seat 47 has an inner hole 49 that matches the steel pipe, and the side has a positioning hole that intersects the inner hole 49. One side of the positioning hole is the hexagonal through hole 15 and the other side is the round through hole 48. The hexagonal head of the hexagonal bo...

Abstract

The invention relates to an impeller aerator, which comprises a motor, a reduction box, an impeller, a support rod, and a floating body, wherein the motor is vertically arranged on the reduction box; a decelerated output shaft is stretched out downwards; a flange is arranged on an end part of the output shaft and is connected with a fixed seat of the impeller; three basically uniformly distributed joints are arranged on the outer side of the reduction box; the support rod is fixed on the joints; a connecting seat is provided with an inner hole matched with a steel pipe; a locating hole intersected with the inner hole is arranged on a side face of the connecting seat; a hexagonal through hole is arranged on one side of the locating hole; a circular through hole is arranged on the other side of the locating hole; a hexagon head of a hexagon bolt enters into the hexagonal through hole; the connecting seat is fastened with the steel pipe through the hexagon bolt; a fixed ring I is arranged on the other end of the steel pipe; the fixed ring I is fastened with the steel pipe through base plates with two holes and two bolts; at least one base plate with two holes is provided with a fixing ring II; the support rod is fixed on the joints through the flange of the connecting seat; the floating body is fixed in the fixed ring I; a rope for fixing the aerator is fixed in the fixing ring II and is hung on a metal fixing ring; and the plastic fixing ring I and the floating body are not stressed, so that the connection is reliable and firm.

Description

technical field [0001] The invention relates to an aerator, in particular to an impeller type aerator, which belongs to fish farming machinery. 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: water wheel type, impeller type and water spray type. Among them, the impeller type aerator is the most widely used, and the supporting device of the impeller type aerator belongs to the impeller type aerator. a component of . One end of the support rod of the usual impeller type aerator is welded with a flange and the other end is welded with a floating ball fixing ring made of iron sheet. After welding, it is easy to rust and the process is complicated. There are also brackets with plastic fixing rings that do not need to be welded, such as Patent: ZL200620008985.3, but when this aerator is in use, the user hangs the rope that fixes the position of th...
