2. Description of the Related Art A conventional organic matter decomposing apparatus has a structure in which a stirring rod having a plurality of blades on the outer circumference of a rotating shaft is rotatably provided horizontally in a decomposing tank. And a microorganism and a propagation material such as sawdust for promoting the decomposition are put into a decomposition tank, and the stored contents of the organic matter, the microorganism and the growth material (hereinafter referred to as a storage material in the specification) are stirred. The rod is rotated to agitate the contents and decompose with microorganisms. However, in the vertical rotation of the blade by the stirring rod, a non-stirred portion such as a corner of the decomposition tank or between the blade and the decomposition tank, which is not easily stirred by the rotation of the blade, is not obtained, and sufficient stirring cannot be obtained. The ability to decompose organic substances could not be fully exerted. Further, a large organic substance was shredded into small pieces by the rotation of the blade, but if it entered the non-stirred portion, it could not be shredded and the decomposition effect was poor.

[0005]

In the present invention, microorganisms are stored in the decomposition tank in advance, and organic substances generated from homes, restaurants, factories, etc. are put into the decomposition tank. As a result, the charged organic matter is mixed with the microorganisms by the driving means by the stirring member provided on the outer periphery of the cylindrical body rotating in the opposite direction to the spiral rod, and the spiral body is rotated while being stirred, whereby the cone at the lower part of the decomposition tank is rotated. Since the stored items gathered near the central part of the shape are lifted up to the upper part of the decomposition tank along the inside of the cylinder, the organic substances stirred by the stirring member cover the lifted stored items from the top and gradually reach the bottom of the decomposition tank. After being swept in, it is guided to the lower opening of the cylindrical body by the blades of the spiral body, is lifted up through the cylindrical body to the upper end opening of the cylindrical body, and is discharged to the uppermost portion of the stored items in the decomposition tank. The stirring member provided on the outer circumference of the cylindrical body breaks down the stored items that tend to volume near the inner wall of the decomposition tank and sends the stored items to the bottom of the decomposition tank evenly. In this way, the contents stored in the decomposition tank are evenly stirred to efficiently decompose organic substances by the microorganisms. Further, since the projecting rod projecting to the lower end of the cylindrical body scrapes the stored item in the lower part of the cylindrical body and rotates in the opposite direction to the spiral body, it is large in the stored item which is guided to the opening at the lower end of the cylindrical body by the spiral blade of the spiral body. When organic matter is mixed and sticks out from the inner diameter of the cylinder, the protruding part is scraped off when it intersects with the spiral blade of the spiral body or is dropped from the blade, and the bottom end opening of the cylinder The clogging of the stored items in the section is eliminated, and rotation stop of the spiral body is prevented.

[0006] When an air blowing device is provided at the bottom of the decomposition tank, air is supplied to the microorganisms to activate the microorganisms,
Improves decomposition efficiency.

When the projecting rod at the lower part of the cylindrical body is inclined and projected as described in claim 3, since the tip of the projecting rod is at the position retracting in the direction opposite to the advancing direction, the storing of the projecting rod is carried out. The load of the object can be reduced, and the intersection between the inclined surface of the projecting rod and the inclined surface of the blade of the spiral becomes sharp, and the shearing force of the protruding portion of the organic material protruding from the inner diameter of the cylindrical body increases. If the cutting portion is provided near the opening of the upper portion of the cylindrical body as described in claims 4 and 5, the stored material that is pumped up from the bottom portion of the decomposition tank and discharged from the opening of the upper portion of the cylindrical body is inserted into the decomposition tank through the cutting portion. As a result, the large organic substances mixed in the pumped-in storage material are shredded and discharged into the decomposition tank and agitated by the stirring member, so that the decomposition efficiency of microorganisms is improved.

According to a sixth aspect of the present invention, the agitating member is obliquely installed so as to lower the tip of the agitating member, and the agitating member base end is displaced from a deep portion of the stored item having a large load to reduce the load applied to the agitating member base end. Also, there is an effect that the contents are pushed down from the tip end to the base end of the stirring member by the rotation, and the contents are evenly sent to the bottom of the decomposition tank.
