As shown in FIG. 1, an exhaust pipe 72 is connected to the rotating pipe 70, and the exhaust pipe 72 is connected to a deodorizing device (not shown). When air is supplied from the air supply passage 18 into the processing tank 16 through the supply hole 19, the air causes the air in the processing tank 16 to flow through the connecting pipe 71, the rotating pipe 70, and the exhaust pipe 72. Sent to the deodorizer.
The air sent to the deodorizing device is deodorized by the deodorizing device.

When the electric motor 32 for the rotating shaft is driven in a state where the garbage is stored in the processing tank 16 shown in FIG. 1, the hollow output shaft 31, the rotating shaft 33, and the mounting body 50 are, for example, 1 / min.
They rotate together at the rotation speed. When the attachment body 50 rotates, the garbage is stirred in the treatment tank 16 by the blades 65a to 65d of the attachment body 50. At this time, when a load due to garbage acts on the mounting body 50 in the radial direction of the rotating shaft 33, portions other than the upper end and the lower end of the main body 51 are elastically deformed in the radial direction of the rotating shaft 33, and the main body 51 rotates. The shaft 33 is displaced in the radial direction. The thickness of the main body 51 is set to a value at which the main body 51 elastically deforms as described above when a load due to garbage acts on the mounting body 50 in the radial direction of the rotating shaft 33.

When a load due to garbage in the radial direction of the rotating shaft 33 acts on the upper end of the mounting body 50, the load is
2, transmitted to the bottom plate 15 via the rotating shaft 33, the housing 29, the mounting plate 26, and the reinforcing plate 25, and the bottom plate 15 is elastically bent and deformed. Due to the bending deformation of the bottom plate 15, the rotation shaft 33 is inclined so as to fall around a portion corresponding to the bottom plate 15 of the rotation shaft 33. The thickness of the bottom plate 15 is a value at which the bottom plate 15 elastically bends and deforms as described above when a load due to garbage acts on the upper end of the mounting body 50 in the radial direction of the rotating shaft 33, for example, about 5 mm. Is set to

Next, the operation of the blade supporting structure in the garbage disposal apparatus configured as described above will be described.
First, the cover 68 shown in FIG. 1 is rotated so that the axis of the rotating pipe 70 becomes the center to open the input hole 67a.
The garbage is put into the processing tank 16 from 7a so that the first to fourth blades 65a to 65d are filled with the garbage.
Further, a treating agent composed of enzymes and bacteria such as amylase, protease and lipase is introduced into the treatment tank 16 from the introduction hole 67a, and then the lid 68 is rotated in the opposite direction to close the introduction hole 67a.

In this state, when the blower 20 is driven by rotating the blower electric motor 21 shown in FIG. 2, air is discharged from the discharge port 20a of the blower 20 to the air supply pipe 22. The air is heated by a heater when flowing through the air supply pipe 22, and then sent out from the air supply pipe 22 into the air supply passage 18.
Is supplied into the processing tank 16 through each supply hole 19.

The electric motor 3 for the rotating shaft shown in FIG.
When the hollow output shaft 31, the rotating shaft 33, and the mounting body 50 are rotated in the direction of arrow A by the drive of No. 2, the blades 65a to 65d of the mounting body 50 are positioned on the rotation orbit of the blades 65a to 65d. Push up garbage. As a result, the garbage is stirred in the processing tank 17 and the garbage and the processing agent are mixed. When the raw garbage stirred in the processing tank 16 comes into contact with the air supplied into the processing tank 16, the raw garbage is decomposed by the processing agent and becomes, for example, an organic fertilizer.

When each of the blades 65a to 65d of the mounting body 50 pushes the garbage, a load due to the garbage acts on each of the blades 65a to 65d. When the load due to the garbage acts on each of the blades 65a to 65d in an uneven manner, or when the garbage is pressed against the mounting body 50, a load acts on the mounting body 50 in the radial direction of the rotating shaft 33. When a load acts on the attachment body 50 in the radial direction of the rotating shaft 33, portions other than the upper end and the lower end of the main body 51 are elastically deformed in the radial direction of the rotating shaft 33. Due to this elastic deformation, the main body 51 is displaced in the radial direction of the rotating shaft 33, and the displacement of the main body 51 absorbs the load acting on the mounting body 50 in the radial direction of the rotating shaft 33.

When garbage is pressed against the upper end of the mounting body 50 and a load acts on the upper end of the mounting body 50 in the radial direction of the rotating shaft 33, the load is applied to the cover 52, the rotating shaft 33, the housing 29, Bottom plate 1 via mounting plate 26 and reinforcing plate 25
Transfer to 5. Since the portion of the bottom plate 15 corresponding to the hollow output shaft 31 is thicker than other portions of the bottom plate 15 by the reinforcing plate 25 and the mounting plate 26, when the load acting on the mounting body 50 is transmitted to the bottom plate 15, The portion of the bottom plate 15 corresponding to the hollow output shaft 31 can be prevented from being plastically deformed.

When the load acting on the mounting body 50 is transmitted to the bottom plate 15, the bottom plate is elastically bent and deformed, and
3 is tilted so as to fall around a portion corresponding to the bottom plate 15 of the rotary shaft 33. When the rotating shaft 33 is inclined, the rotating shaft 33 is displaced in the radial direction, and the radial displacement of the rotating shaft 33 acting on the upper end of the mounting body 50 is absorbed by the radial displacement of the rotating shaft 33.

When the garbage is pressed against the first to fourth blades 65a to 65d, each blade 65a is attached to the mounting body 50.
A load due to garbage in the vertical direction acts through ~ 65d. When the load due to the garbage becomes equal to or more than a predetermined value, the safety bolt 57 shown in FIG. 5 is broken in the radial direction, and the fixing of the mounting body 50 to the rotating shaft 33 in the vertical direction is released. When the fixing between the mounting body 50 and the rotating shaft 33 is released, the mounting body 50 moves in the vertical direction relatively to the rotating shaft 33, and the movement of the mounting body 50 causes the blades 65a to 65d to move. The vertical load of working garbage is absorbed.

To change the height positions of the blades 65a to 65d, the bolts 56 and the safety bolts 57 shown in FIG. 5 are loosened to connect the cover 52 to the main body 51 and to connect the cover 52 to the rotary shaft 33. Cancel. Further, by loosening the adjusting bolt 63 shown in FIG. 6 to separate the connecting member 61 from the head 63a of the adjusting bolt 63, the connecting member 61 is separated from the connected portion 33a, and the connecting surface 61b of the pair of connecting members 61 is connected. Is released from holding the connected portion 33a.

Thereafter, the cover 52 is pulled out upward and detached from the main body 51 to expose the upper surface of the sleeve 45. Then, the tip of a driver or the like is fitted into a groove 46 provided on the upper surface of the sleeve 45, and the sleeve 45 is rotated with respect to the rotation shaft 33. Then, the annular plate 54 of FIG. 5 screwed to the outer peripheral surface of the sleeve 45 moves up and down, and the main body 51 fixed to the annular plate 54 is moved in the vertical direction.
This movement of the main body 51 changes the height position of each of the wings 65a to 65d. After the height position of each of the blades 65a to 65d is changed, the cover 52 is attached to the main body 51 in a reverse procedure to the removal procedure, and the cover 52 and the rotating shaft 33 are returned to a connected state.

In order to replace the mounting body 50 when the blades 65a to 65d are damaged, the detachable plate 67 is removed from the upper plate 12a of the main body case 12 after opening the lid 68 shown in FIG.
Then, the safety bolt 57 shown in FIG.
6 is released, and the adjusting bolt 63 shown in FIG. 6 is further loosened to release the holding of the connected portion 33 a by the connecting surfaces 61 b of the pair of connecting members 61. In this state, when the attachment body 50 is pulled upward, the sleeve 45
3, and the main body 51 is pulled out from the pipe 28.

The mounting body 50 removed from the pipe 28 and the rotating shaft 33 is taken out of the main body case 12 through the large-diameter hole 14 and out of the main body case 12, and thereafter the large-diameter hole 1
4, a new mounting body 50 is put into the main body case 12. Then, by attaching a new attachment body 50 to the pipe 28 and the rotating shaft 33 in the reverse order to the above, the attachment body 50 is replaced. After the attachment body 50 is replaced, the detachable plate 67 is attached to the upper plate 12a of the main body case 12 again.

In this embodiment described in detail above, the following (a)
The following effects are obtained. (A) The load caused by garbage in the radial direction of the rotating shaft 33 acting on the mounting body 50 is absorbed by the mounting body 50 displacing in the radial direction of the rotating shaft 33. Therefore, each blade 65a,
When a load imbalanced to 65d acts or garbage is pressed against the attachment body 50, and the load in the radial direction of the rotation shaft 33 acts on the attachment body 50, the rotation shaft 33 bends in the longitudinal direction. Deformation can be prevented.

(B) Since the mounting body 50 is formed in a cylindrical shape and fitted to the outside of the rotating shaft 33 and the pipe 28, even if the rotating shaft 33 and the mounting body 50 are formed separately, the processing tank 16 It is possible to prevent the mounting body 50 from taking up a large space inside. Therefore, since the amount of garbage stored in the processing tank 16 can be increased, a large amount of garbage can be processed at one time.

(C) The mounting body 50 is formed so as to extend in the same direction as the rotating shaft 33, and only the upper end of the mounting body 50 is connected to the rotating shaft 33 so as to be integrally rotatable. Therefore, when a load is applied to the mounting body 50 in the radial direction of the rotating shaft 33, the rotating shaft 33
Increases the amount of elastic deformation in the radial direction. Therefore, the load acting on the mounting body 50 in the radial direction of the rotating shaft 33 is reduced.
Can be reliably absorbed by the radial displacement of the rotating shaft 33 at

(D) When garbage is pressed against the upper end of the mounting body 50 and a load is applied to the mounting body 50 in the radial direction of the rotating shaft 33, the bottom plate 15 is elastically deformed and deformed.
Or lean. Since the rotating shaft 33 is displaced in the radial direction by tilting, the mounting body 5 is displaced by the displacement of the rotating shaft 33.
