The present invention relates to a grinder.

Background Art Conventionally, a pulverizer for crushing a kitchen waste composed of, for example, vegetables, fruits, fish products, food waste, and the like is known. In the processing of the kitchen waste, by pulverizing the kitchen waste with a pulverizer in advance, the volume of the kitchen waste can be reduced, and the storage property of the kitchen waste can be improved. In addition, since the kitchen waste is made finer, heat is more likely to be transferred, so that drying efficiency of the kitchen waste can be improved. In addition, the decomposition efficiency of kitchen waste can be improved, and the efficiency of composting can be improved.

As a grinding | pulverization machine, the grinding | pulverization machine provided with the some fixed blade disperse-arranged in the columnar shape, and the rotary blade which circumscribes the inside of a fixed blade are known (for example, refer patent document 1). As shown in FIG. 9, the grinder disclosed in patent document 1 is the cylindrical body 100 into which kitchen waste is put, the rotating plate 101 provided in the lower end part of the cylindrical body 100, and the inner peripheral surface of the cylindrical body 100. FIG. A plurality of fixed blades 102 disposed along the side, and a plurality of rotary blades 103 fixed to the rotating plate 101 are provided.

The rotary blade 103 rotates along the rotary plate 101 and passes through the inside of the fixed blade 102. At this time, kitchen waste is cut | disconnected between the outer end 103a of the radial direction of the rotary blade 103, and the inner end 102a of the fixed blade 102. As shown in FIG. In this grinder, such cutting is repeated, and the kitchen waste is continuously grind | pulverized.

[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-179121

However, in the above-mentioned grinder, it is difficult to grind between the fixed blade 102 and the rotary blade 103 when a difficult grinding material (for example, metal spoon or fork, tableware or jewelry, etc.) is mixed in the put-in kitchen waste. In some cases, the water meshes with each other and causes damage to the blades 102 and 103. In addition, the grinding | pulverization difficulty thing pinched | interposed between the fixed blade 102 and the rotary blade 103, and the rotary blade 103 may not move, and operation may stop.

This invention is made | formed in view of such a point, Comprising: It aims at providing the grinder which does not cause a blade breakage or the operation stop of the apparatus, even if the grind | mixing material is mixed in kitchen waste.

 The pulverizer according to the present invention has a tubular body having an inlet through which kitchen wastes are introduced and an outlet through which the kitchen wastes are introduced, and an opposing surface having an opposite surface inclined or perpendicular to a horizontal plane while facing the outlets. The blade, the rotary blade provided in the said opposing surface, the fixed blade which is arrange | positioned facing the said rotary blade and intersects with the said rotary blade as viewed from the opening direction of the said inlet, and the said rotary blade in the surface parallel to the said opposing surface. And a rotating mechanism for rotating the fixed blade to face each other, wherein at least one of the rotary blade and the fixed blade is formed in a ring shape, and the rotary blade and the fixed blade have mutually intersecting angles with the opposite rotation. It is formed to change.

 According to the mill, the rotary blade and the fixed blade rotate relative to each other so that the crossing angle of each other changes. Therefore, the kitchen waste is effectively crushed at the intersection of the rotary blade and the fixed blade. Here, at least one of the rotary blade and the fixed blade is formed in a ring shape. Therefore, the rotary blade and the fixed blade always intersect. Therefore, unlike the case where the rotary blade and the fixed blade intersect intermittently, there is no fear that the crushing difficulty may be engaged between the blades. Therefore, even if it is difficult to grind in the kitchen waste, the breakage of the blade is unlikely to occur. In addition, it is difficult to stop the operation of the grinder.

It is preferable that at least one of the said rotary blade and the said fixed blade is formed in elliptical ring shape.

As a result, the kitchen waste is smoothly pulverized.

It is preferable that the said cylindrical body extends in a vertical direction, and the said opposing board is inclined with respect to a horizontal plane.

As the cylindrical body extends in the vertical direction in this manner, the kitchen waste introduced into the cylindrical body from the inlet is smoothly guided to the inlet by gravity. In addition, since the counter plate is inclined with respect to the horizontal plane, the kitchen waste guided to the counter plate through the outlet port is smoothly discharged along the opposing face by being subjected to gravity while being crushed by the rotary blade and the fixed blade.

The inlet may be formed at one end of the cylindrical body, and the cylindrical body may extend in a direction inclined with respect to the horizontal plane.

This makes it easy to inject kitchen waste into the cylindrical body.

The outlet port is formed at one end of the tubular body, the top plate having an opening corresponding to the outlet port at one end of the tubular body, a bottom plate facing the top plate, and one end covered with the top plate. The other end is covered with the bottom plate, and a casing having a body portion that is a cylinder having a larger inner diameter than the cylindrical body is connected, the fixed blade is fixed to the upper plate, and the counter plate and the rotary blade are housed in the casing. The rotating mechanism may rotate the opposing plate.

As a result, the engagement of the pulverized hard object is prevented and the kitchen waste is effectively crushed.

In the casing, an auxiliary blade having an inner end that is disposed on the outer side of the rotary blade that is circumferentially along the rotation of the opposing plate, and that the rotary blade is circumferentially shifted with the outer end of the rotary blade. It is preferable to have.

Thereby, the kitchen waste grind | pulverized by the rotary blade and the fixed blade is further cut | disconnected by a rotary blade and an auxiliary blade, and it refine | miniaturizes.

It is preferable that a space | interval is formed between the said opposing board and the said bottom board, and the auxiliary board is provided with the auxiliary board fixed to the surface which opposes the said bottom board.

Thereby, the kitchen waste grind | pulverized by the rotary blade and the stationary blade is grind | pulverized by the auxiliary plate in the back of a counter board, and it refine | miniaturizes.

It is preferable to be provided with the stirring member which is fixed to the said opposing board and extends to the said cylindrical body side, and stirs the kitchen waste in the said cylindrical body.

This prevents clogging of kitchen waste in the tubular body.

The shredder is configured to cover the opening of the tubular body freely to open and close, to open and close the detector to detect the open / closed state of the cover, and to detect the opening of the cover by the open / close detector. It is preferable to have the control apparatus to stop.

Thereby, various control based on the opening / closing state of a cover is attained. For example, if the lid is opened during operation, the safety of the grinder can be improved by forcibly stopping the operation.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail based on drawing.

(Embodiment 1)

As shown in Fig. 1, the pulverizer 1 includes an input unit 2 into which kitchen waste is put, a crush unit 3 for crushing the put kitchen waste, and a discharge unit 4 for discharging the pulverized kitchen waste. Equipped with.

The injection | throwing-in part 2 is equipped with the injection | throwing-in cylinder 11 and the cover 12 which closes and opens the upper opening 11e of the input cylinder 11 freely. The input cylinder 11 includes a cylinder 11a extending in the vertical direction, a funnel-shaped tapered cylinder 11b provided at the upper end of the cylinder 11a, and an inclined cylinder 11c provided at the lower end of the cylinder 11a. Consists of. The lid 12 is provided above the tapered barrel 11b. On the other hand, a lever 13 is provided in the cover 12. The tapered barrel 11b is provided with a locking pin 11d protruding outward in the radial direction, and a lever 13 is provided with a ring 14 that engages with the locking pin 11d. As the ring 14 engages with the locking pin 11d, the lid 12 is locked in a closed state.

The sensor 15 which detects the opening / closing state of the lid | cover 12 is provided in the periphery of the upper opening 11e of the tapered cylinder 11b. Arbitrary sensors can be used as the sensor 15 which detects the open / close state. Here, the sensor 15 is formed by a limit switch which detects the open / close state based on the contact state with the lid 12.

As described above, in the present embodiment, the cylinder 11a extends in the vertical direction, and the injection cylinder 11 extends in the vertical direction as a whole. However, the inclined cylinder 11c of the lower end part of the input cylinder 11 is bent from the cylinder 11a, and is extended in the direction inclined from the vertical direction. The upper opening 11e of the injection container 11 is parallel to the horizontal plane, but the lower opening 11f is inclined from the horizontal plane. That is, the lower part of the feed container 11 is formed in the shape which cut | disconnected to the inclined surface S1 inclined from the horizontal plane. Therefore, the periphery of the lower end of the injection | pouring container 11 becomes elliptical shape.

The periphery of the lower opening 11f of the inclined cylinder 11c extends radially outward, and forms the flange-shaped upper plate 21. The lower casing 20 is provided in the upper plate 21 by the bolt 22 and the nut 23. The lower casing 20 is arranged in parallel with the top plate 21 and has a bottom plate 24 facing the top plate 21 and a cylindrical body portion which is raised from the outer circumference of the bottom plate 24 toward the top plate 21. And a flange portion 26 extending radially outward from the outer peripheral portion of the trunk portion 25, and the flange portion 26 and the upper plate 21 are fixed by a bolt 22 or the like.

Inside the lower casing 20, the grinding chamber 27 (refer FIG. 2) which becomes an almost sealed space divided by the upper board 21, the bottom board 24, and the trunk | drum 25 is formed. That is, a casing 28 composed of an upper plate 21, a bottom plate 24, and a body portion 25 is provided at the lower end of the feeding container 11, and the grinding chamber 27 is provided inside the casing 28. This compartment is formed. On the other hand, since the lower end of the feed container 11 is inclined, the casing 28 is also inclined.

The upper plate 21 is provided with an opening 29 corresponding to the lower opening 11f of the injection cylinder 11, and the lower opening 11f and the opening 29 are continuously vertically up and down. Therefore, the kitchen waste put into the feeding container 11 flows into the grinding chamber 27 via the lower opening 11f and the opening 29. As shown in FIG. On the other hand, the inner diameter of the trunk | drum 25 becomes larger than the inner diameter of the injection cylinder 11.

As shown in FIG. 3, the rotating shaft 32 which traverses the bottom plate 24 up and down is arrange | positioned at the center part of the bottom plate 24. As shown in FIG. The sprocket 33 is provided in the lower end part of the rotating shaft 32. As shown in FIG. An angle 37 extending laterally is fixed to the casing 28. The drive motor 36 is supported by the angle 37. The sprocket 35 is provided in the rotating shaft 38 of the drive motor 36. The drive chain 34 is wound around this sprocket 35 and the sprocket 33.

The disc 31 supported by the rotating shaft 32 is arrange | positioned inside the casing 28. Therefore, when the drive motor 36 rotates, the disc 31 rotates in the casing 28.

At the front end side of the rotating shaft 32, the stirring member which stirs the kitchen waste in the input container 11 is provided. Here, the stirring member is formed by the rod-shaped member 55 orthogonal to the rotating shaft 32 (refer FIG. 4). However, neither the shape nor the size of the stirring member is limited, and of course, other stirring members may be used. For example, as shown in Fig. 5, a substantially V-shaped wing member 55 may be used as the stirring member.

As shown in FIG. 3, the outer diameter of the disc 31 is almost equal to the inner diameter of the casing 28. Strictly, the outer diameter of the disc 31 is set slightly smaller than the inner diameter of the casing 28.

The upper surface of the master plate 31 is an opposing surface that faces the lower opening 11f of the feeding cylinder 11. As shown in FIG. 2, four rotating blades 41 are fixed to the opposite surface by screws or the like. Each rotary blade 41 consists of an elongate plate-like object whose cross section is rectangular. The rotary blade 41 is arrange | positioned every 90 degrees along the circumferential direction of the disk 31, and the adjacent rotary blades 41 mutually extend in the direction orthogonal to each other. Each rotary blade 41 is arrange | positioned in parallel with a radius in the position which deviated from the radius of the original plate 31. As shown in FIG.

In addition, the top plate 21 is provided with a fixed blade 42 disposed around the periphery of the opening 29 by a screw or the like. In the present embodiment, since the opening 29 is elliptical, the fixed blade 42 is formed in an elliptic ring shape. The fixed blade 42 is formed in a plate shape having a rectangular cross section. As shown in FIG. 3, the fixed blade 42 faces the rotary blade 41 at a slight interval, and the opening direction of the opening 29 is also the axial direction of the casing 28. As seen from above, the rotary blade 41 and the fixed blade 42 intersect.

As shown in FIG. 2, since there is no broken gap in the fixed blade 42, the rotary blade 41 and the fixed blade 42 always intersect without being restrained by the rotational position of the disc 31. In addition, since the fixed blade 42 is formed in the shape of an elliptic ring, the crossing angle θ between the rotary blade 41 and the fixed blade 42 is continuously changed along the rotation of the disc 31.

In addition, four fixed blades 43 are arranged on the inner circumferential surface of the casing 28 along the circumferential direction. The fixed blade 43 is disposed on the outer side of the rotational trajectory M of the outer edge of the rotary blade 41, so that the rotary blade 41 and the fixed blade 43 do not come into contact with the inner end of the fixed blade 43. A slight gap is formed between the outer ends of the rotary blades 41. As shown in FIG. 3, the thickness of the fixed blade 43 is larger than the thickness of the rotary blade 41. Therefore, with the rotation of the disc 31, the rotary blade 41 passes by the side of the fixed blade 43, and the outer end of the rotary blade 41 and the inner end of the fixed blade 43 are instantaneously in the transverse direction. Adjacent to.

The rotary blade 41 and the fixed blades 42 and 43 are formed of tool steel (engineering tools, such as die steel, for example). However, the material of the rotary blade 41 and the fixed blades 42 and 43 is not specifically limited. The rotary blade 41 and the fixed blades 42 and 43 may be formed from other metal materials, or may be made of nonmetal materials.

The number of the rotary blades 41 and the fixed blade 43 is not particularly limited. In addition, a plurality of fixed blades 42 may be provided. The shapes of the rotary blade 41 and the fixed blade 42 are not limited as long as they always intersect. Instead of the fixed blade 42, the rotary blade 41 may be formed in an elliptic ring shape. In addition, it is also possible to form both the rotary blade 41 and the fixed blade 42 in a circular ring shape (including an elliptical ring shape).

As shown in FIG. 3, a plurality of auxiliary plates 44 extending radially from the center of the disc 31 are fixed to the rear face (the face opposite to the opposing face) of the disc 31. The auxiliary plate 44 rotates along the rotation of the disc 31, and pushes the kitchen waste which is engaged to the back of the disc 31 to the discharge port 51 (see FIG. 1) by centrifugal force. Further, the auxiliary plate 44 cuts the kitchen waste by staggering the inner circumferential surface or the bottom surface of the casing 28.

As shown in FIG. 1, the discharge port 51 is formed in the lowest part in the side surface of the trunk | drum 25 of the inclined casing 28. As shown in FIG. Therefore, the kitchen waste in the casing 28 moves to the discharge port 51 side by gravity, and is discharged smoothly downward from the discharge port 51 obliquely. On the other hand, the discharge pipe 52 is disposed outside the discharge port 51. The discharge part 4 is formed by these discharge ports 51 and the discharge pipe 52.

On the other hand, the grinder 1 is provided with the controller 60 which forcibly stops the operation of the motor 36 when the lid 12 is open.

Next, the operation of the grinder 1 will be described.

First, the user opens the lid 12 and injects kitchen waste from the upper opening 11e. Then, the introduced kitchen waste is introduced into the grinding chamber 27 (inside of the casing 28) through the feeding container 11.

Next, the user closes the lid 12 and turns on the operation switch (not shown) of the grinder 1. On the other hand, when the operation switch is turned on with the cover 12 open by mistake, the operation of the drive motor 36 is prevented by the controller 60. Therefore, driving | operation is not started with the cover 12 open.

When the operation switch is turned on while the lid 12 is covered, the drive motor 36 is started. Then, the driving force of the drive motor 36 is transmitted to the rotating shaft 32 through the drive chain 34, so that the disc 31 and the stirring member 55 rotates.

When the disc 31 rotates, the rotary blade 41 moves around in the state intersecting with the fixed blade 42. At this time, the crossing angle θ of the rotary blade 41 and the fixed blade 42 is continuously changed, and the increase or decrease is repeated.

The kitchen waste introduced from the feed container 11 falls by gravity and is first introduced into the inner region of the fixed blade 42 on the disc 31. The kitchen waste is crushed by the rotary blade 41 and the fixed blade 42. Here, since the rotary blade 41 rotates around while intersecting with the fixed blade 42, the kitchen waste is cut out with scissors, especially at the intersection of the rotary blade 41 and the fixed blade 42. Finely ground

By the way, the hard-to-crush things, such as a metal, may mix in the kitchen waste thrown in. However, in this embodiment, since the rotary blade 41 and the fixed blade 42 always cross | intersect, the grinding | pulverization difficulty thing does not engage between the rotary blade 41 and the fixed blade 42, and is fixed to the fixed blade ( In the inner region of 42, the circumferential movement along the intersection of the two blades 41 and 42 is repeated.

The kitchen waste pulverized in the inner region of the fixed blade 42 moves to the outer region of the fixed blade 42 through the gap between the fixed blade 42 and the disc 31. And the kitchen waste which moved to the outer area | region of the fixed blade 42 is pulverized more finely by the rotary blade 41 and the fixed blade 43. As shown in FIG. That is, when the rotary blade 41 intersects with the fixed blade 43, the kitchen waste located between the rotary blade 41 and the fixed blade 43 is cut by these blades 41 and 43. As shown in FIG.

And the kitchen waste after grinding moves to the outer peripheral side of the original plate 31, and is discharged | emitted through the discharge port 51. FIG. On the other hand, since the casing 28 inclines so that the discharge port 51 may be in the lowest position, the kitchen waste in the casing 28 is easy to move to the discharge port 51 side by gravity. Some of the kitchen waste in the casing 28 moves to the rear of the disc 31, but these kitchen wastes are cut by the staggering of the subplate 44 and the inner circumferential or bottom surface of the casing 28, and further, the subplate 44. It pushes out to the outer peripheral side of the original plate 31, and is discharged | emitted from the discharge port 51. FIG.

By the way, when the difficult-to-crush material is mixed in the put-in kitchen waste, a noise often occurs during operation. As described above, in the present embodiment, the hard grinding material is not crushed and remains in the inner region of the fixed blade 42. Therefore, in the case where noise occurs during operation, it is preferable to determine that the hard grinding material is mixed and to stop the operation or to open the lid 12 to remove the foreign matter after the operation is finished.

On the other hand, when the cover 12 is opened during the operation of the drive motor 36, a signal is sent from the sensor 15 to the controller 60, and the controller 60 stops the operation of the drive motor 36. Therefore, there is no fear that the above-mentioned grinding | pulverization operation | movement is performed in the state which the cover 12 is open. When a noise has occurred, even if the lid 12 is opened without accidentally stopping the operation, the operation is forcibly stopped. Therefore, the foreign matter can be removed as it is.

As described above, according to the crusher 1, the kitchen waste can be effectively crushed at the intersection of the rotary blade 41 and the fixed blade 42. Since the rotary blades 41 and the fixed blades 42 always intersect, even if a grinding material such as metal is mixed in the put-in kitchen waste, there is a fear that the grinding difficulty may be engaged between the blades 41 and 42. There is no. Therefore, breakage of the rotary blade 41 and the fixed blade 42 can be prevented. In addition, according to the pulverizer 1, it is difficult to stop the operation due to the crushing of the difficult to interlock.

According to this embodiment, the fixed blade 42 is formed in an elliptic ring shape. Therefore, the crossing angle (theta) between the rotary blade 41 and the fixed blade 42 can be continuously increased and decreased, and kitchen waste can be effectively crushed.

In addition, according to this embodiment, the feed container 11 is extended in the vertical direction. Therefore, the kitchen waste thrown in from the upper opening 11e is smoothly introduced into the grinding chamber 27 by gravity. In addition, since the original plate 31 is inclined in the horizontal plane, the kitchen waste in the grinding chamber 27 moves to the discharge port 51 side in accordance with the inclination of the original plate 31 and is smoothly discharged from the discharge port 51.

Moreover, according to this embodiment, the fixed blade 43 which staggers with the rotating blade 41 is provided in the inner peripheral surface of the casing 28. As shown in FIG. Therefore, the kitchen waste grind | pulverized by the rotary blade 41 and the fixed blade 42 can be grind | pulverized more finely by the rotary blade 41 and the fixed blade 43.

In addition, according to the present embodiment, the auxiliary plate 44 is provided on the rear side of the original plate 31. Therefore, the kitchen waste moved to the back of the original plate 31 can be cut and further grind | pulverized and can be pushed out to the discharge port 51. FIG.

Moreover, according to this embodiment, the stirring member 55 which rotates with the rotating shaft 32 is provided in the inside of the feed container 11. Therefore, the thrown-in kitchen waste is stirred by the stirring member 55. Therefore, clogging of the kitchen waste inside the feeding container 11 is prevented.

The grinder 1 of this embodiment is provided with the sensor 15 which detects the opening / closing state of the cover 12. As shown in FIG. Moreover, the grinder 1 is equipped with the controller 60 which stops the drive motor 36 when the cover 12 is opened. Therefore, since the cover 12 is not operated in the open state, safety can be improved. In particular, even when the lid 12 is opened without the operation switch being turned off when the pulverized hard object is removed, the driving motor 36 is forcibly stopped, so there is no fear of compromising safety.

In the said embodiment, the feed container 11 is extended in the vertical direction. However, it is also possible to incline the feed cylinder 11 in the vertical direction. For example, as shown in FIG. 6, the input cylinder 11 may be inclined in the vertical direction and the casing 28 may be provided in the horizontal direction. In this case, the discharge port 51 is formed in the downward direction, and the disc 31 (not shown in Fig. 6) is rotated in the vertical plane.

By tilting the feeding container 11 in this way, it becomes easy to put kitchen waste.

(Embodiment 2)

 As shown to FIG. 7 and FIG. 8, the grinder 1 which concerns on Embodiment 2 is equipped with the comb-tooth shaped fixed blade 45 instead of the fixed blade 43 of Embodiment 1. As shown in FIG.

The comb-shaped fixed blade 45 is provided along the inner circumferential surface of the casing 28 without a gap broken in a circular ring shape. The fixed blade 45 is disposed outside the rotational trajectory M of the outer edges of the rotary blade 41 and the auxiliary plate 44 so that the rotary blade 41 and the auxiliary plate 44 and the fixed blade 45 do not contact each other. In order to prevent this, a slight gap is formed between the inner end of the fixed blade 45 and the outer end of the rotary blade 41 and the auxiliary plate 44. As shown in FIG. 7, the thickness (axial length) of the comb-shaped fixed blade 45 is larger than the thickness of the rotary blade 41 and the auxiliary plate 44. As shown in FIG. Accordingly, as the disc 31 rotates, the rotary blade 41 crosses the side of the upper side of the fixed blade 45, and the auxiliary plate 44 crosses the side of the lower side of the fixed blade 45. On the other hand, since the plurality of blades are formed at predetermined intervals along the circumferential direction in the fixed blade 45, the rotary blade 41 and the auxiliary plate 44 are constantly crossed with the blade portion of the fixed blade 45.

Since other configurations are the same as those in the first embodiment, their explanation is omitted.

With this configuration, the kitchen waste which is crushed in the inner region of the fixed blade 42 and moved to the outer region of the fixed blade 42 through the gap between the fixed blade 42 and the disc 31 is a rotary blade 41. ) And the fixed blade 45 is further finely ground. That is, when the rotary blade 41 passes by the stationary blade 45, the kitchen waste located between the rotary blade 41 and the stationary blade 45 is cut by these blades 41 and 45.

The kitchen waste after pulverization moves to the outer circumferential side of the original plate 31 by centrifugal force, and moves further toward the discharge port 51 side by gravity and the inclination of the casing 28, but a part thereof moves to the rear of the original plate 31. do. The kitchen waste moved to the back of the disc 31 is further finely crushed by the auxiliary plate 44 and the fixed blade 45. That is, when the auxiliary plate 44 passes by the stationary blade 45, the kitchen waste located between the auxiliary plate 44 and the stationary blade 45 is cut by the auxiliary plate 44 and the stationary blade 45.

Therefore, according to this embodiment, the kitchen waste grind | pulverized by the rotary blade 41 and the fixed blade 42 can be grind | pulverized more finely by the rotary blade 41 and the comb-shaped fixed blade 45. .

In addition, according to the present embodiment, the auxiliary plate 44 and the comb-shaped fixed blade 45 also with respect to the kitchen waste which is crushed by the rotary blade 41 and the fixed blade 42 and moved to the rear of the original plate 31. Finer grinding).

As described above, the present invention is useful for a grinder for pulverizing kitchen waste.

 As described above, according to the present invention, even when the pulverized material is mixed in the put-in kitchen waste, the pulverized hard material does not mesh between the rotary blade and the fixed blade, so that Damage can be prevented beforehand. In addition, since the operation of the grinder is not caused to stop, it becomes possible to operate the grinder continuously for a long time.
