[Detailed description of the invention]

[0001]

[Industrial application field]
The present invention relates to a stirring claw shaft in a waste disposal apparatus that collects garbage and the like generated at home and intensively treats it.

[0002]

2. Description of the Related Art A conventionally used waste treatment apparatus rotatably supports an agitating claw shaft having a plurality of agitating claws in a fermentation tank and supplies hot air into the fermentation tank. A fermentation process is performed by warm air while stirring the garbage in the fermentation tank with a stirring claw, with the apparatus attached.

[0003]

In the above-described waste treatment apparatus, the agitating claw shaft is formed integrally with the driven shaft and the drive shaft. In the case where the stirring claw shaft is integrally formed with the driven shaft and the drive shaft, assembling cannot be performed unless a large cutout or a hole is formed in the fermenter main body. Therefore,
An object of the present invention is to obtain a stirring claw shaft in a waste device in which the stirring claw shaft, the driven shaft and the drive shaft can be easily assembled.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention provides a stirring claw shaft in a waste treatment apparatus as described below. That is, a stirring claw shaft having a plurality of stirring claws is rotatably supported in the fermentation tank, and a hot air supply device for supplying hot air to the fermentation tank is attached to stir the garbage in the fermentation tank. In a waste disposal apparatus that performs fermentation treatment with warm air while stirring with a nail, the outer shape of the fermenter is formed in a T-shape in a front view, and the fermenter is formed under each of a left overhang portion and a right overhang portion. A drive shaft is formed on each side, a drive system is housed in the left space, a drive system is housed in the right space, and a drive shaft is driven via a motor of the drive system housed in the left space. The other end is a stirring claw shaft in a waste disposal apparatus which is detachably mounted on one end of a stirring claw shaft and the other end thereof is detachably mounted on a driven shaft.

[0005]

The agitating claw shaft is separate from the driven shaft and the drive shaft,
Since it is detachable, it is possible to assemble the stirring claw on the shaft outside and then assemble it into the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a waste treatment apparatus will be described based on the patent application No. 269141 of 1993 filed by the present applicant. As shown in FIG. Is formed in a T-shape, and in the space below the T-shaped overhang, a drive system for the stirring claw shaft, and respective devices such as a drive motor, an air blower of a hot air supply device, a heater, a switch, and other electrical equipment are provided. A space (3) is formed below the left overhang (2) of the fermenter (1), and a drive system (8) is housed in the space (3). One space portion (5) is formed below the overhanging portion (4), and electric components are stored in the space portion (5). The drive system (8) housed in the left space (3) further extends from the left space (3) toward the center of the main body, and is formed in a cave (6) that is recessed from the rear toward the front. The stirrer claw shaft (9) is driven via a drive system (8) from a drive motor (7) housed in the housing.

Next, the electric equipment accommodated in the space (7) on the right side accommodates an air blower (10), and air is introduced from the outlet through a flexible tube to the inlet of the heater (11). The air is heated by the heater (11) and is guided from the outlet of the heater (11) to the nozzle pipe (15) provided at the bottom of the fermenter tank body (1) via the air inlet (12). Warm air is blown from the mouth to promote the fermentation of the processed material with aerobic microorganisms.

[0008] Since the stirring claw shaft (9) of the above-mentioned waste treatment apparatus is integrated with the driven shaft (14) and the drive shaft (15), it is necessary to make a hole in the fermenter tank body (1). Cannot be assembled.

Therefore, in the present invention, as shown in FIG. 1, a stirring claw shaft (9) having a claw (9a), a driving shaft (15), and a driven shaft (1).
4) is formed as a separate body, and the hollow stirring claw shaft (9) is externally mounted on the solid drive shaft (15) and the driven shaft (14), and fixed with pins (16) and (17), respectively. Adopted structure. This fixing structure may employ an arbitrary attaching / detaching structure instead of pinning. With the above structure, when the stirring pawl (9a) is attached to the stirring pawl shaft (9), it is assembled and attached outside, and then the stirring pawl shaft (9) is moved to the drive shaft (15).
And the driven shaft (14), and it is not necessary to make a cutout or a hole for mounting the stirring claw shaft (9) in the fermenter main body (1).

Conventionally, the driving portion and the driven portion of the agitating claw shaft are supported by separate frames, and a structure for that purpose is required. However, as shown in FIGS. 2 and 3, mounting bolts are provided in the main body wall (1a). (16) When the planted bracket (17) is molded into the main body and molded integrally with a synthetic resin, a chassis for mounting the drive unit and the driven unit becomes unnecessary. In the drawing, (18) indicates a shaft insertion hole.

Further, as shown in FIG. 4, the drive unit and the driven unit of the stirring claw shaft both have a bearing case (1) for supporting the shaft (9).
By providing a space (22) between the bearing (20) of (9) and the dust seal (21), the dust seal (2) is provided.
The liquid leaked from 1) accumulates in the space (22) below the bearing (20), and the life of the bearing can be improved by preventing direct contact with the bearing (20). Therefore, the bearing case (19) is configured to have such a size as to form a space that becomes a pool of liquid as described above. (23) is a dust seal holding member.

[0012]

According to the present invention, the outer shape of the fermenter is formed in a T-shape when viewed from the front, and a space is formed below each of the left and right overhangs of the fermenter. A drive system in the left space, a housing for electrical components in the right space, and a drive shaft driven through a motor of the drive system housed in the left space, one end of a stirring claw shaft, Since the other ends are detachably mounted on the driven shafts, the layout of the entire apparatus is good and the apparatus is compact, and the maintenance of the drive system and the electrical system can be performed independently, so that the work efficiency is good. Further, the stirring nail can be assembled outside, and the assembled product can be incorporated into the fermenter without making a large cutout or hole in the fermenter main body.
