Description

  The present invention relates to a garbage processing apparatus that crushes garbage generated in a kitchen or the like, and more particularly to a garbage processing apparatus that improves the uptake of raw garbage during initial crushing.

  There are known two types of garbage processing apparatuses, a hammer mill type and a grinder type, for crushing garbage such as garbage generated in general households and restaurants. In the hammer mill type garbage disposal apparatus, a fixed hammer or a swingable hammer is provided on a disc disposed at the bottom of a cylindrical hopper (see, for example, Patent Documents 1 and 2).

  In the hammer mill type garbage disposal device, the straw put into the hopper is pressed against the inner peripheral surface of the hopper by the centrifugal force generated by the rotation of the disc, and is crushed by the hammer to form a groove formed on the hopper wall surface. Or, it falls downward from the gap between the outer edge of the disc and the inner peripheral surface of the hopper and is discharged to the drain pipe.

  The grinder-type garbage disposal apparatus has a configuration in which rotary crushing blades and radial crushing blades provided with comb-like teeth are radially stacked and accommodated in a hopper (see, for example, Patent Documents 3 and 4). .

  In a grinder-type garbage disposal device, the comb teeth of the rotating crushing blades and fixed crushing blades that are stacked are engaged with each other with a slight gap. Crush it with a scissors at the comb teeth of the blade.

  The pitch between the stacked rotary crushing blades and the fixed crushing blades becomes finer as it goes to the lower layer. It is further finely crushed by the rotary crushing blade and the fixed crushing blade and discharged downward.

  The hammer mill-type garbage disposal device is designed to operate a high-speed disk with a hammer at several thousand rpm to crush the soot in the hopper, and the soot collides with the hammer and the inner surface of the hopper during operation. Thus, there is a problem that the noise and vibration to be crushed and the rotating sound of the disk are loud.

  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, in grinder-type garbage disposal equipment, a relatively light, large, curved ridge, such as grapefruit skin or the cabbage outer leaf that is often thrown away as a ridge, is a rotating crushing blade on the upper side. There is a problem that it cannot be reliably taken in with a fixed crushing blade.

  In this way, if the soot cannot be taken in at the stage of initial crushing, the crushing time will be delayed, such as if the crushing operation is performed for a predetermined time, the wrinkles will remain almost intact and need to be re-executed. There is a problem that leads to.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a garbage disposal apparatus that improves the uptake ability at the time of initial crushing of straw.

  In order to achieve the above-mentioned object, the invention of claim 1 is characterized in that rotating crushing blades and fixed crushing blades are alternately stacked, and the crushing blades are rotationally driven to crush raw garbage with the rotating crushing blades and the fixed crushing blades. In the garbage disposal device that discharges downward, at least a part of the front and rear surfaces or the front surface in the relative rotation direction of the rotary crushing blade or stationary crushing blade arranged at the top in the stacking direction is inclined to form a downward pushing surface It is characterized by that.

  According to a second aspect of the present invention, the rotary crushing blade or the fixed crushing blade on which the pushing surface is formed includes at least one stirring arm extending from the rotation center toward the outer periphery, and the pushing surface is formed on the stirring arm. It is characterized by that.

  The invention according to claim 3 is characterized in that the pushing surface is formed on a rotary crushing blade, and a handle for adjusting the direction of the rotation direction of each rotary crushing blade is formed on the rotary crushing blade.

  According to the present invention, when the scissors are pushed against the pushing surface by the relative rotation operation of the rotary crushing blade and the fixed crushing blade, the scissors are pushed into the lower crushing blade by receiving the force pushed downward. As a result, it is possible to reliably take in the wrinkles with the rotary crushing blade or the fixed crushing blade arranged at the uppermost stage in the stacking direction, and the uptake of relatively light and large wrinkles is improved.

  Therefore, the crushing process can be completed within a predetermined processing time, and a delay in the crushing process time can be prevented.

As the crushing blade in cooperation with the first rotary crushing blade 12 and the third rotary crushing blade 13 shown in FIG. Function.

  A tab 24 is formed at the tip of each arm 23. The tab 24 is fitted into the vertical groove 17 c of the housing 17 to restrict the rotation of the second fixed crushing blade 13. Further, a leg 24 a is formed on the tab 24, and a gap having a predetermined height is formed between the second fixed crushing blade 13 and the fourth fixed crushing blade 15. Further, the inner diameter of the hub 22 is larger than the diameter of a shaft portion described later of the third rotary crushing blade 14 shown in FIG. 8, and has a dimension that does not interfere with the shaft portion of the third rotary crushing blade 14.

  FIG. 8 shows the third rotary crushing blade 14 disposed in the lower stage of the second fixed crushing blade 13, FIG. 8 (a) is a bottom view, and FIG. 8 (b) is a cross-sectional view along BB in FIG. 8 (a). It is. The third rotary crushing blade 14 includes three arms 28 that extend radially from the hub 27 at intervals of 120 degrees. Each arm 28 has a comb tooth portion 28a having a predetermined pitch on the bottom surface.

The first shaft portion 27a is rotatably fitted to the hub 22 of the second fixed crushing blade 13 shown in FIG. The first shaft portion 27a has a substantially D-shaped cross section on the upper end side, and the shaft mounting hole 19a of the first rotary crushing blade 12 shown in FIG. Further, a screw portion 27c to which the nut 29a shown in FIG. 4 is fastened is formed at the tip of the first shaft portion 27a.

  The fourth fixed crushing blade 15 shown in FIG. 9 is rotatably fitted to the second shaft portion 27b. Further, the second shaft portion 27b is formed with an angular shaft portion 27d that fits in the fifth rotary crushing blade 16 shown in FIG. Furthermore, a screw hole 27e for fastening the screw 29b shown in FIG. 4 is formed on the bottom surface of the angular shaft portion 27d.

  FIG. 9 shows the fourth fixed crushing blade 15 arranged at the lower stage of the third rotary crushing blade 14, FIG. 9 (a) is a plan view, and FIG. 9 (b) is a sectional view taken along the line CC in FIG. 9 (a). FIG. 9C is a DD cross-sectional view of FIG.

  The fourth fixed crushing blade 15 has a shape in which a ring 32 surrounds eight arms 31 extending radially in a tangential direction from the hub 30 at equal intervals. On the outer periphery of the ring 32, tabs 32a protruding in the radial direction at intervals of 180 degrees are formed. The tab 32 a is fitted in the vertical groove 17 c of the housing 17 and restricts the rotation of the fourth fixed crushing blade 15.

  The tab 32a has a predetermined height, and the leg portion 24a of the second fixed crushing blade 13 is placed on the upper surface of the tab 32a, so that the tab 32a is interposed between the second fixed crushing blade 13 and the fourth fixed crushing blade 15. A gap having a predetermined height is formed. Further, the inner diameter of the hub 30 is larger than the diameter of the second shaft portion 27b of the third rotary crushing blade 14 shown in FIG. 8, and has a dimension that does not interfere with the second shaft portion 27b.

  The fourth fixed crushing blade 15 has eight arms 31, and the six arms 31 have comb teeth 31 a formed on the upper surface. The comb teeth 31a of the fourth fixed crushing blade 15 has a pitch that meshes with the comb teeth 28a of the third rotary crushing blade 14 shown in FIG. 8, and as shown in FIG. When the four fixed crushing blades 15 are overlapped, the comb tooth portions 28a and 31a of both are in a meshing state in which a slight gap is formed.

  Thereby, the comb-tooth part 31a of the 4th fixed crushing blade 15 crushes the garbage sent from the upper crushing blade in cooperation with the comb-tooth part 28a of the third rotary crushing blade 14.

  As described above, since the number of the arms 28 of the third rotary crushing blade 14 is three and the number of the arms 31 of the fourth fixed crushing blade 15 is eight, the distance between the arms 31 is narrower than the distance between the arms 28.

  For this reason, when the comb teeth 31a are provided on all eight arms 31, the comb teeth 31a of the fourth fixed crushing blade 15 always exist between the arms 28 of the third rotary crushing blade 14, and a certain amount of When a block-shaped raw garbage of a size is thrown in, a phenomenon occurs in which the raw garbage does not enter between the arms 28 of the third rotary crushing blade 14 and is not easily crushed.

  Therefore, in the fourth fixed crushing blade 15, among the eight arms 31, for example, the two arms 31 b are not provided with the comb-tooth portion 31 a, so that the third rotary crushing blade 14 is rotated during the rotation operation. When the arm 31 not provided with the comb tooth portion 31a of the four fixed crushing blade 15 is positioned between the arms 28 of the third rotary crushing blade 14, a wide space is formed in the circumferential direction.

  As a result, even when block-shaped garbage having a certain size is introduced, the garbage enters between the arms 28 of the third rotary crushing blade 14, and the comb tooth portion 28 a is rotated by the rotation of the third rotary crushing blade 14. The garbage is crushed in cooperation with the comb tooth portion 31 a of the other arm 31 of the fourth fixed crushing blade 15.

  In addition, since there are many arms 31 which do not provide the comb-tooth part 31a in the 4th fixed crushing blade 15, crushing capability will fall, for example, when providing the eight arms 31, the arm 31b which does not provide the comb-tooth part 31a Is preferably about two.

  Further, each arm 31 extends radially along the tangential direction of the hub 30, so that when the third rotary crushing blade 14 rotates, the meshing point with the fourth fixed crushing blade 15 is shifted in the circumferential direction. Therefore, the crushing load peak is suppressed and the load is flattened.

  As shown in FIG. 9C, the fourth fixed crushing blade 15 has pressing surfaces 33 formed on both front and rear surfaces of each arm 31. The pressing surface 33 is an inclined surface (tapered surface) inclined in a direction in which the upper end protrudes from the lower end on both side surfaces of the arm 31.

  The fifth rotary crushing blade 16 shown in FIG. 10 rotates while rubbing against the bottom surface of the arm 31 of the fourth fixed crushing blade 15. The pressing surface is formed by forming the pressing surfaces 33 on both side surfaces of the arm 31. A force of pressing the fifth rotary crushing blade 16 against the garbage (which has been crushed to a certain size) in contact with 33 can be applied by rotating the fifth rotary crushing blade 16.

  On one side surface of each arm 31, a corrugated surface 34 in which vertical grooves are arranged in parallel is formed. Accordingly, during the rotation operation in one direction of the fifth rotary crushing blade 16 shown in FIG. 10, the garbage is caught by the concave portion of the corrugated surface 34, and the movement of the garbage in the radial direction is suppressed, so that the garbage is reliably It can be crushed.

  FIG. 10 shows the fifth rotary crushing blade 16 disposed in the lower stage of the fourth fixed crushing blade 15, FIG. 10 (a) is a plan view, and FIG. 10 (b) is a cross-sectional view taken along line EE in FIG. 10 (a). FIG. 10C is an enlarged cross-sectional view of the main part.

  The fifth rotary crushing blade 16 has a disk shape, and a large number of slits 39 are arranged on the entire surface excluding the central hub 38. In the fifth rotary crushing blade 16 of this example, a plurality of slit groups are formed, and in each slit group, adjacent slits 39 are arranged substantially in parallel.

  The upper surface of the fifth rotary crushing blade 16 is a flat surface and rotates while contacting the bottom surface of each arm 31 of the fourth fixed crushing blade 15 shown in FIG. Further, the slit 39 shown in FIG. 10 penetrates the fifth rotary crushing blade 16 from the front and back, and a sharp edge is formed at the upper opening side opening edge of the slit 39.

  The raw garbage that has been crushed by the comb tooth portion 28a of the third rotary crushing blade 15 shown in FIG. 8 and the comb tooth portion 31a of the fourth fixed crushing blade 15 shown in FIG. When the fifth rotary crushing blade 16 rotates by being caught by 39, it is pressed against the slit 39 by the pressing surface 33 of the fourth fixed crushing blade 15 and is crushed by the edge portion of the slit 39. The finely crushed garbage is dropped downward through the slit 39, passes through the bottom plate 9 of the hopper 3 shown in FIG. 2, and is discharged from the drain pipe connection port 8 to the outside.

  As shown in FIG. 10C, the slit 39 is formed with a stepped portion 39a, and the opening on the bottom surface side is enlarged from the opening on the upper surface side so that the garbage pushed into the slit 39 can easily fall. It is. Thereby, the raw garbage pushed into the slit 39 by the pressing surface 33 of the fourth fixed crushing blade 15 is likely to fall downward.

  The hub 38 of the fifth rotary crushing blade 16 is formed with a square hole 38a into which the angular shaft portion 27d of the third rotary crushing blade 14 shown in FIG. Further, a square hole 38b into which the drive shaft 5a shown in FIG. Further, a through hole 38c through which the screw 29b shown in FIG. 4 passes is formed between the square hole 38a and the square hole 38b.

  Next, the assembled state of each crushing blade will be described with reference to FIGS. The hub 30 of the fourth fixed crushing blade 15 is rotatably fitted to the second shaft portion 27b of the third rotary crushing blade 14, and the angular shaft portion 27d of the second shaft portion 27b is the corner of the fifth rotary crushing blade 16. It fits into the hole 38a.

  Then, the screw 29b is fastened to the screw hole 27e of the square shaft portion 27d from the square hole portion 38b side of the fifth rotary crushing blade 16, and the third rotary crushing blade 14 and the fifth rotary crushing blade 16 are integrally configured. .

  Further, the hub 22 of the second fixed crushing blade 13 is rotatably fitted to the first shaft portion 27a of the third rotary crushing blade 14, and the shaft mounting hole of the first rotary crushing blade 12 is further fitted to the first shaft portion 27a. 19a is non-rotatably fitted.

  And the nut 29a is fastened by the screw part 27c of the 1st axial part 27a, and the 1st rotation crushing blade 12 and the 3rd rotation crushing blade 14 are comprised integrally, and the 1st rotation crushing blade 12 and the 3rd rotation crushing blade are comprised. The blade 14 and the fifth rotary crushing blade 16 are integrated with the second fixed crushing blade 13 and the fourth fixed crushing blade 15 in between.

  In addition, the attachment of each crushing blade integrated into the housing 17 as described above is performed by fitting the tab 24 of the second fixed crushing blade 13 and the tab 32a of the fourth fixed crushing blade 15 into the vertical groove 17c of the housing 17. Thus, the second fixed crushing blade 13 and the fourth fixed crushing blade 15 are held by the housing 17 so as not to rotate.

  Then, by holding the holding metal 17d in the vertical groove 17c and fixing with a screw or the like (not shown), the crushing blades are held in the up-down direction impossible by the holding metal 17d and the flange portion 17b. As a result, the first rotary crushing blade 12, the third rotary crushing blade 14, and the fifth rotary crushing blade 16 are rotatable with respect to the housing 17.

<Operation of garbage disposal device>
Next, the operation of the garbage processing apparatus 1 shown in FIG. 1 will be described. First, the overall operation of the garbage disposal apparatus 1 will be described with reference to each drawing. When garbage is introduced from the input opening 7 and the input opening 7 is closed by the lid 11, for example, a control means (not shown) Then, it is detected that the closing opening 7 is closed by the lid 11 and the motor 6 is rotated. Specifically, a rotation operation that repeats the forward rotation and the reverse rotation operation is performed every few seconds, for example, every 5 seconds. The rotation speed of the motor 6 is set to about 100 rpm, and the generation of noise and vibration is suppressed.

  Note that a water supply hole (not shown) is formed in the lid body 11 so that water can be supplied into the hopper 3 even when the inlet opening 7 is closed by the lid body 11. Water is supplied into the hopper 3 by flowing water into the hopper 3.

  When the motor 6 rotates, the crushing unit 4 has the first rotary crushing blade 12, the third rotary crushing blade 14, and the fifth rotary crushing blade 16 integrally rotated. In contrast, the second fixed crushing blade 13 and the fourth fixed crushing blade 15 do not rotate.

  As a result, the garbage thrown into the hopper 3 from the charging opening 7 is stirred by the stirring arm 20 of the first rotary crushing blade 12 and roughly in cooperation with the arm 23 of the second fixed crushing blade 13 at the lower stage. The crushed raw garbage is fed between the arms 28 of the third rotary crushing blade 14.

  The garbage sent between the arms 28 of the third rotary crushing blade 14 is rotated by the rotation of the third rotary crushing blade 14 between the comb teeth 28a of the arm 28 and the arm 31 of the lower fourth fixed crushing blade 15. It is finely crushed by meshing with the comb teeth portion 31a.

  Here, the 4th fixed crushing blade 15 is provided with the comb-tooth part 31a by rotation of the 3rd crushing blade 14 by providing the arm 31b which does not provide the comb-tooth part 31a in the some arm 31. When the non-arm 31b is positioned between the arms 28 of the third rotary crushing blade 14, a large space is formed in the circumferential direction. Thereby, even large garbage such as a block shape enters between the arms 28 of the third rotary crushing blade 14, and the rotation of the third rotary crushing blade 14 causes the comb tooth portion 28a of the third rotary crushing blade 14 and the fourth fixed The crushing blade 15 is finely crushed by meshing with the comb teeth portion 31a of the other arm 31.

  Thereby, the garbage which mixed various sizes can be crushed with the combination of a small number of fixed crushing blades and rotary crushing blades.

  Garbage crushed by the cooperation of the third rotary crushing blade 14 and the fourth fixed crushing blade 15 is discharged from the slit 39 by the cooperation of each arm 31 of the fourth fixed crushing blade 15 and the fifth rotary crushing blade 16. Is done.

  That is, when the garbage comes into contact with the pressing surface 33 of the upper arm 31 by the rotation of the fifth rotating crushing blade 16, the garbage is pressed downward in the direction of the fifth rotating crushing blade 16 by the inclination angle of the pressing surface 33. Receive the power to be.

  Thereby, the garbage is pressed against the slit 39 by the pressing surface 33 by the rotation of the fifth rotary crushing blade 16, is crushed by the edge of the opening edge of the upper surface side of the slit 39, and is further pressed by the pressing surface 33 to be slit. It passes through 39 and falls downward.

  As described above, the slit 39 is formed with the step portion 39a, and the opening on the bottom surface side is larger than the opening on the top surface side. Therefore, the raw garbage pushed into the slit 39 passes through the step portion 39 a and moves to a wide portion, and falls downward without being clogged by the slit 39.

  In the garbage processing apparatus 1, for example, after the motor 6 is rotationally driven for a certain time, a control unit (not shown) stops the driving of the motor 6. The driving time of the motor 6 is set in consideration of the time required for crushing a standard amount of garbage thrown into the hopper 3 and discharging it from the drain pipe connection port 8.

  Next, details of the operation of the first rotary crushing blade 12 will be described. FIG. 11 is an operation explanatory diagram showing a garbage taking-in operation by the first rotary crushing blade 12. The garbage disposed in the hopper 3 shown in FIG. 1 and the like has various sizes before the crushing operation. For example, relatively light and large garbage such as grapefruit skin is often placed on the first rotary crushing blade 12 or the second fixed crushing blade 13 before the crushing operation. When each rotary crushing blade rotates from this state and the first rotary crushing blade 12 rotates, for example, in the direction of arrow F, the garbage 41 abuts against the pushing surface 21 of the stirring arm 20 as shown in FIG.

  Since the pushing surface 21 is a slope inclined in the direction in which the upper end protrudes with respect to the lower end, the garbage 41 is pushed downward as indicated by the arrow U by the rotation operation of the first rotary crushing blade 12 in the arrow F direction. Receive.

  As a result, as shown in FIG. 11B, the garbage 41 is pushed downward and crushed by the cooperation of the first rotary crushing blade 12 and the second fixed crushing blade 13, and further, the lower crushing blade. It is crushed finely.

  Therefore, the uptake | capture property of the garbage in an initial crushing stage improves, a crushing process can be complete | finished within predetermined processing time, and the delay of a crushing process time can be prevented.
