Abstract

<P>PROBLEM TO BE SOLVED: To provide a garbage disposer capable of fracturing a tough continuous fiber such as vegetables. <P>SOLUTION: A fifth rotatable fracturing blade 18 having fracturing holes 37 penetrated in a disc from its top to flip side is disposed at the undermost part and a fourth stationary fracturing blade 17 is made to touch the surface of the fifth rotatable fracturing blade 18. A garbage dropped on the plane of the fifth rotatable fracturing blade 18 from the upward is cut by the edges of the fracturing holes and the fourth stationary fracturing blade 17 to fall from the fracturing holes. A thin and tough continuous fiber can be surly cut without being clogged in the gap of the fracturing blades. The number of fracturing times is increased by forming many fracturing holes so as to enhance fracturing efficiency. A drain pipe is not clogged since only a constant amount of a fracturing object is always discharged because the fracturing object falls only from the fracturing holes. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a garbage disposal apparatus for crushing garbage generated in a kitchen or the like. Specifically, the rotary crushing blades and the fixed crushing blades are alternately stacked, and when any of the rotary crushing blades and the fixed crushing blades is constituted by a disc-shaped main body, the thickness of the disc-shaped main body is penetrated. The present invention relates to a garbage disposal apparatus with improved crushing performance by drilling a number of crushing holes and crushing garbage with the crushing holes while bringing the crushing blades into surface contact.

  There are known two types of garbage processing apparatuses for crushing garbage used in general households and restaurants, a hammer mill type and a grinder type. For example, a hammer mill type garbage disposal apparatus as disclosed in Patent Document 1 and Patent Document 2 is provided with a fixed hammer or a swingable hammer on a disk disposed at the bottom of a cylindrical hopper. Yes. Garbage thrown into the hopper is pressed against the inner peripheral surface of the hopper by centrifugal force generated by the rotation of the disk, and is crushed by these hammers. The crushed garbage falls downward from a groove formed on the wall surface of the hopper or a gap between the outer edge of the disk and the inner peripheral surface of the hopper. The shredded garbage that has fallen is discharged to the drain pipe side.

  A grinder-type garbage disposal apparatus (for example, Patent Documents 3 and 4) is housed in a hopper by alternately laminating rotary blades and fixed blades provided with comb-shaped blades radially. The comb-tooth blades of the rotary blade and the fixed blade are engaged with each other with a slight gap. When the rotary blade rotates, the comb-tooth blades of the rotary blade and the fixed blade sandwich the garbage. The pitch between the stacked rotary blades and the fixed blades of the comb-tooth blades becomes finer toward the lower layer. Therefore, the garbage thrown into the hopper is first roughly crushed by the upper rotary blade and the fixed blade, further finely crushed by the lower rotary blade and the fixed blade, and discharged downward.

JP 2001-70818 A JP 2002-292300 A JP-T-2002-521193 JP-T-2002-524233

  The hammer mill type garbage processing device is designed to operate a high-speed disk with a hammer at several thousand revolutions (rpm) to pulverize the garbage in the hopper. Since it collides with the surface and is crushed, there are disadvantages that the noise and vibration are large and the rotating sound of the disk is large.

  On the other hand, a grinder type garbage disposal apparatus having a structure in which rotating blades and fixed blades are alternately stacked does not require the use of centrifugal force, so that the number of rotations can be reduced and noise can be reduced. However, both the hammer mill type and the grinder type have insufficient ability to treat strong fibery vegetable waste and seafood skins, etc., and these fibrous wastes remain in the hopper or are entangled with the blade. May be frustrated. Therefore, there is a problem that it takes time and effort to remove these wastes, and time and effort to remove these fibrous wastes from garbage.

  Therefore, the present invention solves such a conventional problem, and provides a garbage disposal apparatus having a low noise and an ability to treat fibrous garbage that cannot be treated by a conventional garbage disposal apparatus.

  The garbage processing apparatus according to the first aspect of the present invention is configured by alternately laminating rotary crushing blades and fixed crushing blades, and rotationally driving the rotary crushing blades to crush the garbage with the rotary crushing blades and the fixed crushing blades. In the garbage disposal apparatus that discharges downward, the crushing blade body having a disk shape is equipped with a rotary crushing blade or a fixed crushing blade having a number of crushing holes drilled through the thickness thereof, and the crushing hole It is characterized by cutting the garbage thrown in at the edge of.

  In the present invention, a crushing unit is configured by housing a rotating crushing blade (movable crushing blade) and a stationary crushing blade alternately stacked in a cylindrical housing. The crushing unit is inserted into a hopper provided on the lower surface of the kitchen sink. The hopper is provided with a rotating shaft driven by a driving motor, and the rotational force is transmitted to the rotating crushing blade by being connected to the shaft of the crushing unit.

  Among the stacked crushing blades, the second fixed crushing blade and the third rotary crushing blade located in the upper stage are comb-shaped blades that mesh with each other, and are formed on the lower surface of the third crushing blade. A comb-like blade is also provided. Then, the comb-shaped blade provided on the lower surface of the third rotary crushing blade and the fourth fixed crushing blade mesh with each other. A fifth rotary crushing blade is provided for the fourth fixed crushing blade so as to be in surface contact with the lower surface thereof.

  The fifth rotary crushing blade has a disk-shaped main body, and a number of crushing holes penetrating in the thickness direction are formed in the main body. As the crushing hole, a round hole, a square hole (polygonal hole having three or more corners), an elliptical hole, or a long hole is used. Of course, a crushing hole can be configured by combining any of these hole shapes.

  In the case of long holes, if they can be unified with the same size, the size can be slightly changed according to the position where they are drilled. When long holes are used, those having a relatively short long side (about four times the short side) are used. The arrangement of the crushing holes is also arbitrary. It may be arranged radially around the axis of the disk-shaped body, arranged linearly (parallel to the x-axis or y-axis), or arranged in an involute shape. Alternatively, a combination of these is also possible.

  By configuring the crushing hole in this manner, the garbage is finely crushed by the surface contact between the fifth rotary crushing blade and the fourth fixed crushing blade located immediately above the fifth crushing blade. Depending on the number of crushing holes formed in the fifth rotary crushing blade, the maximum flow rate of the crushed garbage is restricted, and the flow rate (crushing discharge amount) of the crushed material passing through the crushing holes is regulated. Therefore, the crushing discharge amount is always almost constant. Therefore, the crushed material is not discharged to the drain pipe side at once. As a result, the drain pipe is not clogged. Since the maximum crushing particle diameter is determined by the diameter of the crushing hole, it is possible to cope with a case where the diameter of the drain pipe is thin.

  In this invention, using a crushing unit in which fixed crushing blades and rotating crushing blades are alternately stacked, the garbage is sequentially sent to the lower crushing blade side for crushing, and the crushing that forms a disk shape as the lowermost crushing blade Using a blade, this crushing blade is provided with a number of crushing holes, and this crushing blade is rotated between the crushing blade and the other crushing blade that comes into surface contact with this crushing blade, so that the garbage is finely cut. is there.

According to this, the garbage can be cut finely, and the flow amount of the crushed material passing through the crushing holes is regulated, so that the crushing discharge amount can be made substantially constant at all times. For this reason, the crushed material is not discharged to the drain pipe at a time, thereby preventing the drain pipe from being clogged.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an application example of a garbage disposal apparatus 1 installed in a kitchen facility. In FIG. 1, reference numeral 2 denotes a housing, and a cylindrical hopper 3 is mounted on the housing 2, and the upper end of the hopper 3 is fitted to the drainage port of the kitchen sink S. A detachable crushing unit 11 is inserted into the hopper 3, and the lower end portion of the shaft 12 of the crushing unit 11 is fitted to the drive shaft of the reduction gear unit 4. Since the motor 5 accommodated in the housing 2 is connected to the reduction gear unit 4 disposed in the housing 2, the shaft 12 of the crushing unit 11 is rotationally driven via the reduction gear unit 4.

  Although the reduction gear unit 4 and the motor 5 are linearly arranged with respect to the hopper 3, the motor 5 can also be arranged on the side of the reduction gear unit 4.

  FIG. 2 shows the hopper 3. 2A is a plan view of the hopper 3, FIG. 2B is a longitudinal sectional view of the hopper 3, FIG. 2C is a side view thereof, and FIG. .

  The hopper 3 is an upright cylindrical part, and is provided with a connection port 6 for a drain pipe (not shown) at the lower end of the peripheral surface, and is inclined toward the drain pipe connection port 6 inside the hopper 3. A bottom plate 7 is provided, and a hole (square hole) 8 through which the drive shaft of the reduction gear unit 4 passes is formed at the center of the bottom plate 7.

  FIG. 3 is an exploded perspective view of the crushing unit 11 accommodated in the cylindrical housing 13, and FIG. 4 is a cross-sectional view showing a state in which the crushing unit 11 is assembled and accommodated in the housing 13.

The crushing unit 11 is configured by alternately laminating rotary crushing blades and fixed crushing blades. FIG. 3 shows an example in which the crushing unit 11 is composed of four crushing blades.
As shown in FIGS. 3 and 4, the crushing unit 11 includes a cylindrical housing 13 with a first stirring blade 14, a second fixed crushing blade 15, a third rotating crushing blade 16, a fourth fixed crushing blade 17, and a fifth. By accommodating the rotary crushing blade 18, it is configured as a single unit.

  Four crushing blades 15 to 18 are inserted into the housing 13 in order from the bottom in the order shown in FIG. 3 via the shaft 12 provided on the first stirring blade 14. The rotary crushing blades and the fixed crushing blades are held in an alternately stacked state by a C ring 20 fitted in a ring groove 19 (see FIG. 4) formed in the inner peripheral portion of the lower end in the housing 13.

  As shown in FIG. 4, the second fixed crushing blade 15, the third rotary crushing blade 16, and the fourth fixed crushing blade 17 are selected so as to have a mutual dimensional relationship so as to overlap with almost no gap between the upper and lower outer peripheral portions. ing. Thus, the cut object to be crushed does not enter the upper and lower gaps of the outer periphery of the crushing blade and remain in the crushing unit 11. This is to prevent residues.

  The outer diameter of the housing 13 is substantially equal to the inner diameter of the hopper 3, and the crushing unit 11 loaded in the hopper 13 is held on the inner peripheral surface of the hopper 3. Details will be described later. Further, as shown in FIG. 3, the crushing unit 11 is attached to and detached from the hopper 3 by a handle 23 attached to the upper inner surface of the housing 13. As shown in FIG. 4, a shaft fitting adapter 21 is inserted into the lower end portion 12 a of the shaft 12, and the drive shaft of the reduction gear unit 4 and the shaft 12 are connected by the adapter 21. A washer 22 is inserted between the adapter 21 and the lowermost crushing blade 18.

The components of the crushing unit 11 are shown in FIGS.
FIG. 5 is a configuration example of the housing 13. 5A is a plan view thereof, FIG. 5B is a longitudinal sectional view thereof, and FIG. 5C is a bottom view thereof.

  As shown in FIG. 5, three longitudinal grooves 24 are provided on the inner peripheral surface of the housing 13 from the lower end side to the middle portion thereof at an interval of approximately 120 degrees. The outer peripheral side ends of the second fixed crushing blade 15 and the fourth fixed crushing blade 17 are engaged with these vertical grooves 24 (see FIG. 4). By engagement with the vertical grooves 24, the second fixed crushing blade 15 and the fourth fixed crushing blade 17 are fixed to the housing 13, respectively.

  A recess 13 a having a predetermined depth is formed at the upper end of the housing 13. The dent 13a is a dent for inserting a lid (shown in FIG. 1 with a chain line).

  FIG. 6 shows a configuration example of the first stirring blade 14 located in the uppermost layer. FIG. 6A is a plan view, and FIG. 6B is a side view thereof. Two blades 25 extending horizontally in the radial direction from the upper part of the shaft 12 provided at the center of the first stirring blade 14 are provided, and the blade 25 is surrounded by a ring 26 having a diameter substantially equal to the inner diameter of the housing 13. It is out. As shown in FIG. 6B, the blade 25 has a structure in which a plate portion 25b is attached to the lower surface of the arm portion 25a having a cylindrical cross section.

  Thus, by comprising the blade | wing 25 by 2 components, garbage can be efficiently sent below at the time of rotation rather than the flat thing of a plate only, for example. Furthermore, it is possible to prevent tangling of long fibers such as vegetables and garbage from adhering to the upper surface of the arm portion 25a. As shown in FIG. 6B, the lower portion of the shaft 12 is a square shaft 12a having a square cross section in this example, and the square shaft holes of the third rotary crushing blade 16 and the fifth rotary crushing blade 18 are formed in the square shaft 12a. Each can be fitted.

  FIG. 7 shows an example of the second fixed crushing blade 15. 7A is a plan view thereof, FIG. 7B is a side view thereof, FIG. 7C is a transverse sectional view of FIG. 7A, and FIG. 7D is a bottom view thereof.

  The second fixed crushing blade 15 is composed of a hub 27 and spokes 28 extending from the hub 27 in three directions at intervals of 120 degrees, and the lower surface of the spoke 28 is formed with a comb tooth portion 28a having a rough pitch.

  The outer diameter of the spoke 28 is larger than the inner diameter of the housing 13 and is selected so that the tips of the three spokes 28 are engaged with the vertical grooves 24 on the inner peripheral surface of the housing (see FIG. 4). The diameter of the central hole of the hub 27 is larger than the diameter of the square shaft 12a of the first stirring blade 14, and is set to a size that does not interfere with the square shaft 12a. Thus, the first stirring blade 14, the third rotary crushing blade 16 and the fifth Only the rotary crushing blade 18 rotates, and the second fixed crushing blade 15 and the fourth fixed crushing blade 17 described later are not rotated.

  FIG. 8 shows an example of the third rotary crushing blade 16. 8A is a plan view thereof, FIG. 8B is a side view thereof, FIG. 8C is a cross-sectional view of FIG. 8A, and FIG. 8D is a bottom view thereof.

  The third rotary crushing blade 16 has spokes 30 that are equally spaced from the hub 29 and extend in the seven directions in this example, and each tip portion of the spokes 30 is connected to the ring 31. As shown in FIG. 8C, the upper and lower surfaces of the spoke 30 are formed in a comb-tooth shape, and the shape of the upper comb-tooth portion 30 a is the same as that of the comb-tooth portion 28 a formed on the lower surface of the second fixed crushing blade 15. I'm making an even number to match each other.

  And the comb-tooth part 28a of the 2nd fixed crushing blade 15 and the upper surface comb-tooth part 30a of the 3rd rotation crushing blade 16 are comb-toothed so that it may mesh | engage with a slight gap | interval, as shown in FIG. The pitch and blade height are designed.

  On the other hand, as shown in FIG. 8 (c), the comb tooth portion 30b formed on the lower surface has a smaller comb tooth pitch than the upper comb tooth portion 30a, and the comb teeth of the fourth fixed crushing blade 17 described below. A pair is formed so as to mesh with the portion 33a. Thus, the crushing particle size becomes finer in steps from the upper part to the lower part of the sink S. As shown in FIG. 8A and the like, the shaft hole of the hub 29 has a square shape, and is fitted to the square shaft 12 a of the first stirring blade 14 and rotates together with the first stirring blade 14.

  FIG. 9 shows an example of the fourth fixed crushing blade 17. As shown in FIG. 9 (a), the fourth fixed crushing blade 17 has spokes 33 extending in eight directions from the hub 32 at equal intervals, and the comb teeth portion 33a formed on the upper surface of the spoke 33 has the above-described first shape. A pair is formed so as to mesh with the comb tooth portion 30b provided on the lower surface of the three-rotating crushing blade 16. Therefore, as shown in FIG. 4, when the third rotary crushing blade 16 and the fourth fixed crushing blade 17 are overlapped, the comb tooth portions 30b and 33a are engaged with each other with a slight gap.

  The outer ring 34 connected to the spoke 33 is formed with tabs 35 protruding in the radial direction at intervals of 120 degrees. These tabs 35 are ridges for fixing the fourth fixed crushing blade 17 to the housing 13, and are engaged with the longitudinal grooves 24 in the housing 13 as shown in FIG. The crushing blade 17 is fixed to the housing 13.

  The spoke 33 is formed in the tangential direction of the hub 32. This is because, when the third rotary crushing blade 16 rotates, the meshing point between the third rotary crushing blade 16 and the fourth fixed crushing blade 17 is radial. This is because the peak of the crushing load is suppressed and the load is flattened by moving to.

  As shown in FIG. 9 (b), the corners between the side surfaces 33b (vertical surface consisting of the front surface and the rear surface in the rotation direction) and the bottom surface of the spoke 33 are sharp edges, and will be described later in the fifth rotation. By rubbing the bottom surface of the spoke 33 against the crushing blade 18, long fibers such as vegetables can be cut at this edge.

  Both side surfaces 33b of the spokes 33 are wavefronts in which vertical grooves are formed side by side as shown in FIG. 9A, and the vertices of the wavefronts form edges. By using the wave surface having this edge, the object to be crushed is captured by the concave portion of the wave surface at the time of meshing with the third rotary crushing blade 16 and sliding with the fifth rotary crushing blade 18 described below. The movement of the direction can be suppressed and the object to be crushed can be crushed reliably.

  The side surface shape of the spoke 33 may be a triangular wave shape or a trapezoidal shape in addition to the wave shape, but a shape having no corners in the concave portion of the wave front is preferable in terms of discharging garbage. Only one side surface of the spoke 33 may be a wave surface, and the other side surface may be flat.

  As described above, the number of spokes of each crushing blade 15, 16, 17 is different from 3 for the 2nd fixed crushing blade, 7 for the 3rd crushing blade, and 8 for the 4th crushing blade. In addition, the number of spokes of the overlapping crushing blades is made not to have a multiple relationship with each other. By setting the number of spokes to such a value, generation of a crushing load peak during the garbage disposal operation is prevented, and the driving load is averaged.

FIG. 10 shows an example of the fifth rotary crushing blade 18. 10A is a plan view thereof, FIG. 10B is a sectional view thereof, and FIG. 10C is a partially enlarged sectional view of FIG.
The fifth rotary crushing blade 18 is composed of a disc-shaped main body 18a, and a number of crushing holes 37 are formed on the entire surface excluding the hub 36 provided at the center of the disc surface so as to penetrate the thickness. As the shape of the crushing hole 37, various shapes such as a round hole, a square hole, an elliptical hole, and a long hole can be applied.

  The example of FIG. 10 shows an example of the crushing hole 37 by a long hole. The size of the long holes is uniform. The long hole is a long hole whose ratio of short side a to long side b satisfies a: b = 1: n (n ≦ 4). FIG. 10 shows an example of n = 4. A plurality of long holes are formed at predetermined pitches in the x-axis direction and the y-axis direction so as to be parallel to the y-axis of the board surface (xy plane). The x-axis direction is arranged with a pitch twice as long as the short side a, and the y-axis direction is arranged with a pitch of 4a.

  The reason for using the crushing hole 37 made of the long holes selected in such a dimensional relationship is to regulate the size of the crushing hole 37 so that the crushed material is finely cut and dropped, and the crushing hole 37 is used. This is because the cutting particle size (crushing particle size) of the crushed material passing through is made equal to or less than a predetermined particle size.

  As shown in FIG. 10C, the edge on the lower surface side of the crushing hole 37 is chamfered. By performing this chamfering process, the opening area of the lower surface opening is larger than that of the upper surface opening. Thereby, there is no possibility that the garbage pushed into the crushing hole 37 remains attached to the crushing hole 37, and the garbage is easily dropped.

  Since the fifth rotary crushing blade 18 is constituted by the disk-shaped main body 18a, the upper surface thereof is a flat surface and rotates while contacting the lower surface of the fourth fixed crushing blade 17 as shown in FIG. Garbage crushed by the third rotary crushing blade 16 and the fourth fixed crushing blade 17 further falls on the upper surface of the fifth rotary crushing blade 18. The fallen garbage is further caught in the crushing hole 37. Since the fifth rotary crushing blade 18 is a rotary blade, it is cut by the edge of the crushing hole 37 and the edge of the bottom surface of the fourth fixed crushing blade 17. The cut garbage is dropped downward through the crushing hole 37, slides down on the inclined bottom plate 7 of the hopper 3 shown in FIG. 1, and is discharged to the drain outlet 6 side.

  In this way, the fourth fixed crushing blade 17 and the fifth rotary crushing blade 18 are brought into surface contact to cut the object to be crushed, so that conventional garbage processing such as long fibers such as vegetables and seafood skins is performed. Even those that are difficult to process with the apparatus can be reliably cut finely and discharged without being entangled in the crushing holes 37 or clogging the gaps between the crushing blades.

  By providing the fifth rotary crushing blade 18, the amount of crushed crushed material falling from the fifth rotary crushing blade 18 can be suppressed to a constant amount. Therefore, even when the amount of crushed material is large, only a certain amount of crushed material always falls every rotation, so that a large amount of crushed material does not flow down to the drain pipe at one time, and the drain pipe can be prevented from being clogged. Moreover, there is no possibility that the drain pipe is clogged even if the pipe diameter of the drain pipe is thin by keeping the cut grain size of the crushed material below a predetermined grain size.

  Since the crushing unit 11 can be attached to and detached from the hopper 3, it is easy to disassemble each component as shown in FIG. 3, and a fifth rotating crushing blade having a different crushing particle size according to the type of garbage to be processed. Can be replaced. Replacement of worn crushing blades, removal of clogged foreign matter, and disassembly and cleaning can be easily performed. Moreover, since the inside of the hopper 3 can be washed and cleaned by removing the crushing unit 11 from the hopper 3, it is possible to always keep the garbage processing apparatus, which tends to be a source of bad odor due to the attached garbage, cleanly. .

FIG. 11 shows a modification of the arrangement state of the fifth rotary crushing blades 18.
FIG. 11A shows an example in which the crushing holes 37 are arranged in the normal direction of the hub 36. FIG. 2B shows an example in which the crushing holes 37 are arranged in the tangential direction of the hub 36. FIG. 4C is an example in which crushing holes 37 are provided in an involute shape, and FIG. 4D is a diagram in which a plurality of crushing holes 37 arranged in parallel are divided into several groups with different angles between the groups. It is an example of arrangement. When the crushing hole 37 is provided at a different angle as shown in FIG. 11 (d), the size of the long hole (ratio of short side to long side) as shown in FIG. A number of long holes can be formed in the same disk-shaped main body 18a by slightly changing from the other parts.

  In addition, regarding the drive of the crushing unit 11, it is not necessary to rotate at high speed like a hammer mill type garbage processing apparatus, and a sufficient processing speed can be obtained at a low rotation of 200 rpm or less. As an example, the garbage discharged from the household can be processed by driving for about 30 seconds to 1 minute while reversing the rotation direction every 5 seconds at 100 rpm. Low noise drive can be realized due to low rotation. Use of multiple crushing blades enables highly efficient waste disposal.

  Although not shown, the motor drive circuit is provided with a drive current detection circuit and a stop control circuit. When the drive current rises above the overload reference value, the drive of the motor 5 is automatically stopped. As a result, the motor drive is automatically stopped when dust is clogged or an overcurrent flows due to a foreign object such as metal being caught, so that the crushing blade and the motor can be prevented from being damaged. The operation time of one cycle can be controlled by a timer so as to stop at a fixed time during normal operation. Alternatively, the motor 5 may be controlled to stop after a certain period of time after the waste crushing process is finished and the driving load is reduced and the driving current is reduced to the no-load reference value.

  As a means for improving the practicality of the garbage disposal apparatus, it is possible to prevent the garbage from adhering by coating the inner surface of the housing 13, the crushing blade 15 or the like with a fluorine-based resin or plating. If the housing 13 or the crushing blade 15 or the like is used, the metal pieces in the garbage can be adsorbed to the housing 13 or the like, so that clogging of foreign matters or damage to the blade can be prevented.

  In Example 1, a long hole is used as the crushing hole 37. FIG. 12 shows an example in which a round hole is used as the crushing hole 37. Even in the case of a round hole, the lower surface of the disk-shaped main body 18a is chamfered. The size and arrangement pitch of the round holes are arbitrary, but if the diameter becomes too large, the drain pipe is clogged, and therefore an inner diameter of about 2 to 4 mm is actually preferable. Even in the case of round holes, an arrangement example as shown in FIG. 11 can be considered.

  When a long hole is used as the crushing hole 37, the ratio of the short side to the long side is 1: 2 as shown in FIG. 13A, 1: 3 as shown in FIG. 13B, 1: 4 shown in Example 1, etc. Examples are possible. Of course, if workability is ignored, a ratio other than such an integer may be selected.

  The shape of the crushing hole 37 can be applied to other than the long hole and the round hole. FIG. 14A shows an example of a square hole. The square hole may be a polygonal hole having a triangular shape or more. FIG. 6A illustrates a hexagonal square hole.

  FIG. 14B shows the case of an elliptical hole. If the ratio (a: b) between the minor axis and the major axis of the ellipse is increased, the number of holes that can be drilled in the disk-shaped main body 18a is reduced. Therefore, the ratio is preferably about 1: 2.

  Also, different shapes of crushing holes can be used in combination. For example, in FIG. 11D, if the upper and lower sides of the disc-shaped main body 18a are round holes and the left and right sides thereof are long holes, any garbage can be efficiently collected. Can be crushed and cut.
