Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulverizing / stirring machine particularly suitable as a pulverizing / stirring mechanism for a garbage disposer, but can also be applied to various kinds of pulverizing / stirring such as feed and cement.

[0002]

2. Description of the Related Art Conventionally, raw garbage and treated bacteria have been uniformly mixed,
Various structures have been proposed as garbage disposal machines for crushing bones, twigs, and the like.

However, in any of the structures, since the inside of the processing tank is partitioned by a cylindrical body, the circulation passage for the object to be processed is narrow.
Not only cannot mass processing be performed, but the object to be processed cannot move smoothly.

[0004] As a result, when a large amount of water is added or a large amount of water is contained in the object, the stirring is not performed smoothly and sufficiently, and the object adheres to the inner surface of the processing machine. For this reason, a cavity is formed on the bottom, which prevents the convection action of the object to be processed and causes a ball having small nuclei as a nucleus.

[0005] In addition, even if it has a function of crushing a hard object such as a bone or a hard object to be crushed into small pieces, it may not be possible to reliably crush the object.

[0008] The technical problem of the present invention is to focus on such a problem and to realize a structure that can reliably perform convection stirring and pulverization and that can perform a large amount of processing.

[0007]

The technical problem of the present invention is solved by the following means. According to a first aspect of the present invention, a motor disposed outside the processing tank is connected to a lower portion of a drive shaft that stands through the center of a fixed blade arranged and fixed in a tom-like shape on the bottom side of the processing tank. A radial rotary blade is connected to the upper portion of the drive shaft, and each of the fixed blade-shaped cutter blades has a curved shape so as to be convex in the traveling direction of the rotary blade. It is a pulverizing stirrer.

[0008] As described above, since the radial rotary blade is connected to the tom-shaped fixed blade disposed and fixed on the bottom side of the processing tank and is rotatably driven by the motor outside the tank, the fixing is performed. Since the rotating blade moves like a pair of scissors against the blade,
A hard workpiece such as a bone is reliably ground between the two.

In particular, since each of the tomical cutter blades of the fixed blade has a curved shape so as to be convex toward the traveling direction of the rotary blade, the object to be processed follows the curved cutting edge of the fixed blade. As it moves while sliding, the sharpness is improved. The object to be processed remaining without being crushed is finally cut at the position where the rotating blade is closest to the rotation center and has the strongest crushing power, so that it can be crushed reliably.

[0010] A second aspect of the present invention provides an output of a motor disposed outside the processing tank at a lower portion of a drive shaft standing through a center of a fixed blade arranged and fixed on the bottom side of the processing tank. A shaft is connected, and a radial rotary blade is connected to an upper portion of the drive shaft. A spiral formed of a band-shaped plate outside the rotary blade, and curved in the same direction as the curvature of the fixed blade. This is a pulverizing stirrer in which a spiral inclined plate is provided, and the spiral inclined plate is supported in the processing tank by connecting the spiral inclined plate to the outer end of each rotary blade.

As described above, the spiral inclined plate made of a band-shaped plate is disposed outside the rotary blade, and the spiral inclined plate is connected to the outer end of each rotary blade. And, since the spiral inclined plate is curved in the same direction as the curvature of the fixed blade, the spiral inclined plate rotates in the same direction as the rotary blade together with the rotary blade, so that the processing target in the processing tank is processed. Stirring is continuously performed by repeating the operation in which the object moves upward from below on the spiral inclined plate, rises, and falls near the upper end.

According to a third aspect of the present invention, the sloping side of the helical inclined plate according to the second aspect is curved in the same direction as the curvature of the tom-shaped cutter blade of the rotary blade, and is gradually twisted so as to be narrow in the width direction. The inside is gradually raised, and when it comes to the scraping plate, it is almost in a standing shape, and the end of the slope is gradually twisted to form a shape in which the inside in the width direction is gradually lowered. It is a stirrer.

[0013] As described above, the lower slope of the spiral inclined plate is curved in the same direction as the tom-shaped cutter blade, and is gradually twisted so that the inner side in the width direction is gradually increased. In this case, since the workpiece is formed almost upright, the workpiece under the fixed blade is scraped out by the scraping plate, and then pushed up onto the spiral inclined plate.

On the other hand, the upper end of the hill is formed so that the inside in the width direction is gradually lowered by being gradually twisted. At the end of the side, it descends to the rotation center side of the rotary blade, and the pulverizing process is performed between the rotary blade and the fixed blade.

In this way, the convection operation in which the object to be processed climbs on the spiral inclined plate and descends to the rotation center side of the rotary blade, whereby the object to be processed is smoothly stirred. .

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of how the pulverizer / stirrer according to the present invention is actually embodied will be described. 1 to 3 are views showing the internal structure of the pulverizer / stirrer according to the present invention. FIG. 1 is a plan view, FIG. 2 is a front view, FIG.
FIG. 4 is a plan view showing only the fixed blade. FIG. 5 is a perspective view showing the entire internal structure.

In these figures, a bottom plate 1 made of a thick plate is used.
A cylinder 2 is fixed at the center of the cylinder 2, and a tomical fixed blade 3 is fixed to the upper end of the cylinder 2, and the outer end of each fixed blade 3 is connected by a ring 4.

An output shaft 5 of a motor M arranged below the bottom plate 1 is connected to a rotary shaft 6 inside the cylinder 2 and three rotary blades 7 are radially connected to the rotary shaft 6. Has been fixed.

Although the rotary blade 7 in the illustrated example rotates clockwise, the sharpness is improved by inclining the fixed blade 3 toward the arrival direction of the rotary blade 7. Further, the rotary blade 7 is inclined in a direction opposite to that of the fixed blade 3.

A cylindrical casing 8 stands from the outer periphery of the disc-shaped bottom plate 1, and a charging port 9 is opened at the upper right of the casing 8, and an opening / closing lid 10 is attached. In addition, the outlet 1
1 is open and has an open / close lid 12.

A spiral inclined plate 13 is provided with a slight gap from the inner surface of the cylindrical casing 8. The spiral inclined plate 13 is formed of a band-shaped plate, and has a start end (lower slope end) 1.
The section 13b between the end 3a and the end (upper slope) 13c has a substantially horizontal cross-sectional shape in the width direction.

The spiral inclined plate 13 is curved in the same direction as that of the tomographic fixed blade 3. The spiral inclined plate 13 is connected and fixed to the outer end of each rotary blade 7 by a connecting bar 14.

Slope lower end (starting end) 13a of spiral inclined plate 13
And the outer end of one rotary blade 7a are connected by a connecting plate 15. And the slope lower end 13a of the spiral inclined plate 13
And continues to a scraping plate 16 extending toward the cylinder 7.

The portion of the scraping plate 16 is in a substantially upright state, but is gradually twisted from the scraping plate 16 toward the lower slope end 13a of the spiral inclined plate 13. That is, as is apparent from FIG. 5, as the spiral inclined plate 13 advances from the upper side to the lower side of the slope, the horizontal portion in the width direction is gradually twisted, so that the inside is raised so as to be higher. . Then, when it reaches the portion of the scraping plate 16, it is almost in a standing state (the scraping plate 16).
May be slightly inclined).

Therefore, when the rotary blade 7 rotates clockwise in the drawing, the spiral inclined plate 13 also rotates clockwise at the same time, and the object to be processed on the bottom plate 1 is scraped outward by the scraping plate 16.

Then, the lower slope portion 13a of the spiral inclined plate 13
Moves in such a manner as to sink under the object to be processed, and the object to be processed gradually climbs on the spiral inclined plate 13 from the lower slope 13a.

Immediately outside the outer periphery of the spiral inclined plate 13,
Since the inner surface of the cylindrical casing 8 exists with a slight gap, the object to be processed cannot fall to the outside of the spiral inclined plate 13, but climbs to the upper side of the spiral inclined plate 13.

The upper slope, that is, the end portion 13c, of the spiral inclined plate 13 is twisted so that the inner side in the width direction is lower than the lower slope 13a. Therefore, the spiral inclined plate 1
The object to be processed, which has climbed up the upper part 3, gradually falls inward when it reaches the upper slope 13c. At this time, since the object to be processed falls on the rotary blade 7, the bone and the like are crushed between the rotary blade 7 and the fixed blade 3, and descend toward the rotation center of the rotary blade 7.

After being scraped out again by the scraping plate 16, the lower slope 13 a of the spiral inclined plate 13
, And climbs on the spiral inclined plate 13.

The method of use is to put garbage into the treatment tank containing chips or rice bran mixed with fermenting microorganisms through the inlet 9.
An object to be processed is contained up to a level L at which 3c is hidden. Therefore, on the upper surface L of the processing object, the upper slope 13c
The operation is such that only the portion turns while rising.

Since the motor chamber 17 and the upper part of the casing 8 are connected by the duct 18, the wind generated in the motor chamber 17 is blown into the casing 8 through the duct 18 and passes through the casing 8. And is discharged from the exhaust port 19. As a result, it is possible to suppress the odor from drifting in the casing 8.

The casing 8 shown in FIGS. 2 and 3 is swelled like a drum, whereas the casing shown in FIG. 5 is cylindrical. As a result, the lower slope 13a of the spiral inclined plate 13
2 and 3 are slightly different from each other so as to follow the inner circumference of the cylinder. An inlet 9 for the object to be processed is opened at the top.

In the illustrated example, the lower side 1 of the spiral inclined plate 13
Although 3a and the scraping plate 16 are integrally continuous, a structure in which separate members are connected and integrated is also possible. In addition, when the width of the spiral inclined plate 13 is increased, a larger amount of garbage can be removed.
It can be pushed up and dropped to improve the stirring efficiency, but the dimension in the width direction can be set arbitrarily.

As described above, the internal space of the casing 8 is
Since it is not divided by a cylinder or the like, a large amount of garbage can be charged, and a processing tank having the same volume as the conventional one can achieve a processing capacity of 3 to 4 times. Moreover, even relatively large garbage can be smoothly moved and crushed by stirring without being caught or sticking on the way.

[0035]

According to the first aspect of the present invention, a radial rotating blade is connected to a tomical fixed blade arranged and fixed on the bottom side of the processing tank, and the structure is driven to rotate by a motor outside the tank. Since the rotary blade moves like a pair of scissors with respect to the fixed blade, a hard workpiece such as a bone or the like is reliably crushed between the two.

In particular, since each of the tomical cutter blades of the fixed blade has a curved shape so as to be convex toward the traveling direction of the rotary blade, the object to be processed follows the curved cutting edge of the fixed blade. As it moves while sliding, the sharpness is improved. The object to be processed remaining without being crushed is finally cut at the position where the rotating blade is closest to the rotation center and has the strongest crushing power, so that it can be crushed reliably.

According to the second aspect, a spiral inclined plate made of a band-shaped plate is disposed outside the rotary blade, and the spiral inclined plate is connected to the outer end of each rotary blade. And, since the spiral inclined plate is curved in the same direction as the curvature of the fixed blade, the spiral inclined plate rotates in the same direction as the rotary blade together with the rotary blade, so that the processing target in the processing tank is processed. Stirring is continuously performed by repeating the operation in which the object moves upward from below on the spiral inclined plate, rises, and falls near the upper end.

According to the third aspect, the sloping side of the spiral inclined plate is curved in the same direction as the tom-shaped cutter blade.
Moreover, the inside of the width direction is gradually increased by being gradually twisted, and when the scraping plate portion is formed, it is almost in an upright shape, so that the workpiece below the fixed blade is scraped outward by the scraping plate. And subsequently pushed up onto the spiral ramp.

On the other hand, since the end on the upper side of the hill is formed so as to be gradually twisted so that the inner side in the width direction becomes gradually lower, the object to be processed climbing on the spiral inclined plate is moved upward. At the end of the side, it descends to the rotation center side of the rotary blade, and the pulverizing process is performed between the rotary blade and the fixed blade.

In this way, the convection operation is performed in which the object to be processed climbs the spiral inclined plate and then descends toward the rotation center of the rotary blade, whereby the object to be processed is smoothly stirred. .
