Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer for a garbage disposal apparatus for decomposing garbage.

[0002]

2. Description of the Related Art Conventionally, composters have been widely used as this type of kitchen waste disposal apparatus. The composter consists of a tubular body and a lid that covers the top opening of the tubular body. The bottom opening of the tubular body is placed on the ground, and the garbage that has been put into the tubular body through the top opening is subjected to soil bacteria. However, the rate of composting was slow, and there was a problem with the processing capacity.

[0003] In addition, there is a method in which garbage is crushed and dehydrated, and the garbage is automatically dumped in a garbage bag.
It has been proposed in 156959. However,
In this method, it is necessary to dispose of the garbage stored in a garbage bag or the like, which requires time and effort in disposal processing, and poses a problem from the viewpoint of environmental conservation.

[0004] In order to solve these problems, various types of garbage disposal apparatuses have been proposed in which kitchen garbage is discarded in a processing tank containing a processing medium for culturing microorganisms, and the kitchen garbage is eliminated by the microorganisms.

[0005] In the garbage processing apparatus using microorganisms, it is necessary to stir the microorganisms from the necessity of uniformly mixing the microorganisms with the garbage, and various stirring techniques have been proposed.
For example, a technique has been proposed in which an arm is provided on a rotating shaft and a plow is attached to the arm.

[0006] The end face of this plow is oriented in the direction of movement of the arm,
The arcuate plate-shaped support portion warps in the direction opposite to the traveling direction of the arm, and a slanted flange portion that rakes up the raw material formed at the tip of the arcuate plate-shaped support portion (Japanese Unexamined Patent Application, First Publication No. Hei 1 (1994)).
-290580).

[0007]

The stirring technique using a plow requires the use of a plurality of arms to attach each plow, which not only has the disadvantage of complicating the apparatus, but also has the disadvantage of having a slanted flange. Although the bottom of the fermentation chamber where the part slides can be raked, there is a disadvantage that the entire bottom cannot be raked, and in order to solve this, many arms are used, and the plow of each arm is used. It is necessary to change the position, and there is a disadvantage that the device becomes more complicated.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned inconvenience and to provide a stirring device for a garbage disposal apparatus which can improve the efficiency of garbage decomposition treatment.
