Description

[Detailed Description of the Invention] The present invention relates to a device that can easily supply oxygen to stored water in fish and shellfish culture ponds through aeration from land.

In order to cultivate fish and shellfish, it is necessary to prevent the water from stopping in the reservoir and to effectively supply oxygen, and the conventional method for accomplishing this has been to agitate the surface of the reservoir with an agitating blade.

However, conventional agitation devices generally have a structure in which a large frame-shaped float is placed in a suitable position in a reservoir, a tower is assembled on top of it, and a series of agitators including a motor and transmission are attached to it. However, it is very large-scale and cannot easily stir the water surface from land, and it also requires a special submersible motor, which has the disadvantage of being relatively expensive.

In order to deal with these conventional drawbacks, the present invention is designed to provide an inexpensive device of this type that has a simple structure, can be easily operated, and can provide effective aeration depending on the water level by implementing the method described below. It is provided to

The details will be explained below with reference to the embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a motor that is rotatably supported on a bracket l-2 about a support shaft 3, and a hand-type motor that is easy to carry is generally used.

1a is its handle. Reference numeral 4 denotes a rotating shaft that extends forward from the front end of the motor 1. Flows 1-5 are freely rotatably attached to the tip of the rotating shaft, and a stirring blade that moves together with the rotating shaft 4 is located slightly in front of it. Car 6 is attached.

This impeller 6 has a plurality of blade plates 6a, front and rear mounting plates 6b,
6C and radially relative to the rotating shaft 4, and has a truncated conical outer shape as a whole.

Reference numeral 7 denotes a large number of small drainage holes formed on the surface of the blade plate 6a.

Further, a web 8 having a V-shaped cross section is provided on the outer edge of the blade plate 6a over its entire length.

A bracket 2 for pivotally supporting the motor 1 is rotatably mounted on a clamp 9 that can be fixed to a fixed part in a pinching manner.

The clamp 9 is a so-called portable vise type in which two opposing clamping pieces 9a and 9b are moved near and far by the screw movement of a screw rod 9C, and this is clamped from above onto the side edge 10 of a suitable fixing part. It is fixed in an immovable manner by screwing the screw rod 9C.

There is a protruding shaft 9d on the clamp 9, and a bracket 2 is attached to it.
By inserting the center hole 2b provided in the seat bottom plate 2a, and by providing an arcuate long hole 2e in the seat bottom plate 2a and fitting the fixing pin 9e on the clamp 9 side into this, the bracket 2 is fixed within the range of the long hole. It is rotatable around the protruding shaft 9d.

Further, the support shaft 3 of the motor 1 protrudes on both left and right sides, and is fitted from above into the recessed grooves 2d of two opposing support pieces 2C, 2C that protrude upward from the bottom plates of the brackets 1 and 2. Using this as a fulcrum, the motor 1 and rotating shaft 4 can tilt downward like a seesaw in a straight line.

The flow 1-5 preferably has a spherical shape, but may have any other suitable shape such as a cone or an ellipsoid.

The float 5 is freely rotatable with respect to the rotating shaft 4, but is fixed by a stopper 11 in the longitudinal direction of the shaft.

However, if necessary, it should be made slidable in the axial direction so that its mounting position can be varied.

The mounting position of the impeller 6 with respect to the rotating shaft 4 is also adjustable using a stopper 12 in the same way as the float.

In the above configuration, the bracket l-2 is connected to the clamp 9 and the cellar l-L is attached to the side edge 10 of the fixed part of the aquaculture pond or the like.
When the support shafts 3, 3 of the motor 1 are fitted into the recessed grooves 2d of the bracket 2, the impeller 6 facing above the water surface is supported by the float 5 and the bracket 1-2 and moved downward as shown in FIG. Part of it will be submerged in water.

When the motor 1 is started in this state, the impeller 6 rotates together with the rotating shaft 4, and the water on the water surface is scraped up by the blades 6a that are sent one after another.

Also, at this time, the V-shaped paddles splash the water up into the air.

Furthermore, the small holes 7 on the surface of the blade plate 6a generate air bubbles to further enhance the aeration effect below the water surface.

Since the present invention has the above-mentioned configuration, the impeller directly connected to the motor can be easily attached to the cellar 1 at a fixed point such as on the shore of a pond, instead of assembling it on a float by assembling a large grate on the water surface as in the past. It is very simple and easy to operate compared to similar products, and since the motor is not submerged in the water, there is no need to worry about electrical leakage, making it highly safe. Regardless of the water level, constant stirring can be performed at all times depending on the height of the water level.

In addition, practical effects such as a simple structure, durability, and low cost can be expected.
