<Example of configuration of crushing chamber assembly of this embodiment>
FIG. 7 is a perspective view of a crushing blade assembly constituting the basket of the present embodiment. FIG. 8 is an exploded perspective view of the crushing blade assembly of the present embodiment as viewed from above, and FIG. 9 is an exploded perspective view of the crushing blade assembly of the present embodiment as viewed from below.

  In the crushing blade assembly 30, the flap 32, the bridge 33, the first cutter 34, the second cutter 35, and the third cutter 36 are arranged coaxially with the shaft portion 36 a that is the center of rotation of each rotary crushing blade.

  Next, details of the configuration of the flap 32 will be described with reference to the drawings. The flap 32 disposed at the uppermost stage of the crushing blade assembly 30 includes a single stirring arm 32b extending horizontally from the side of the bearing portion 32a, and pushing surfaces 32c are formed on both front and rear surfaces in the rotational direction of the stirring arm 32b. The

  The pushing surface 32c is a slope inclined in a direction in which the upper end protrudes from the lower end on both side surfaces of the stirring arm 32b.

  The flap 32 is formed with the pushing surfaces 32c on both side surfaces of the stirring arm 32b, so that it is possible to apply a downward pressing force to the ridges that are in contact with the pushing surface 32c by the rotation operation in both the forward and reverse directions. Thereby, the flap 32 takes in the cocoon by rotation operation and pushes it into the lower crushing blade.

  In addition, the flap 32 is configured by a surface in which the lower end side of the pushing surface 32 c is substantially vertical, and functions as a crushing blade that crushes the ridges roughly in cooperation with the lower bridge 33.

  Further, the flap 32 is formed with a handle 32d protruding laterally at the upper part of the bearing portion 32a. Since the flap 32 is configured to rotate integrally with each rotary crushing blade, by forming the handle 32d on the uppermost flap 32, the handle 32d can be operated without directly touching the crushing blade. Each rotary crushing blade can be rotated.

  That is, when the basket 3 removed as shown in FIG. 1 is attached to the crushing chamber 2, when adjusting the direction of the crushing blade assembly 30 in the rotational direction for connection with the fitting portion 41a of the drive shaft 41, By operating the handle 32d, the direction of the rotation direction of the crushing blade assembly 30 can be adjusted without directly touching the crushing blade.

  The flap 32 has a shaft mounting hole 32e formed through the bearing portion 32a. The shaft attachment hole 32e has a substantially D-shaped cross section and is fitted in a shaft portion (described later) of the first cutter 34 so as not to rotate.

  Next, details of the configuration of the bridge 33 will be described with reference to the drawings. The bridge 33 disposed in the lower stage of the flap 32 is formed with a hub 33a centering on the rotation axis of the rotary crushing blade, and includes two arms 33b extending outward from the hub 33a.

  The hub 33a of the bridge 33 has a first shaft portion so that an inner diameter of a hole portion into which a first shaft portion (34c) described later of the first cutter 34 is inserted does not become a rotation load of the first cutter 34. It is configured to be larger than the outer diameter.

  The arms 33b extend horizontally from positions at 180 ° intervals on the outer peripheral surface of the hub 33a. Each arm 33b has a flat plate shape whose both side surfaces are substantially vertical, and functions as a crushing blade in cooperation with the flap 32, which is a rotary crushing blade, and the first cutter 34.

  In the bridge 33, the upper surface and the lower surface of each arm 33b may be configured as horizontal surfaces, but in this example, the lower surface of the outer portion of each arm 33b protrudes toward the first cutter 34 and protrudes 33c. Is formed. The inner side of each arm 33b close to the hub 33a is configured with a horizontal surface. Thereby, each arm 33b is thicker on the outer side than on the inner side.

  The bridge 33 is formed with a leg 33d at the outer tip of each arm 33b. The bridge 33 has its leg 33d fitted in the groove 31b of the housing 31 shown in FIG. Further, a gap having a predetermined height is formed between the bridge 33 and the second cutter 35 so that the first cutter 34 can rotate so that the bridge 33 does not tilt with respect to the rotation axis of the rotary crushing blade. Composed.

  Next, the details of the configuration of the first cutter 34 will be described with reference to the drawings. The first cutter 34 arranged at the lower stage of the bridge 33 is formed with a hub 34a centering on the rotation axis, and includes three arms 34b extending outward from the hub 34a.

  Further, the first cutter 34 includes a first shaft portion 34c constituting a rotating shaft on the upper surface of the hub 34a on the side into which the rod is inserted, and the second shaft portion 34d is discharged from the rod. On the lower surface of the hub 34a.

  The arms 34b extend radially from positions at 120 ° intervals on the outer peripheral surface of the hub 34a. Each arm 34b has a comb tooth portion 34e formed on the bottom surface facing the second cutter 35 disposed in the lower stage. The comb-tooth portion 34e has a concave-convex shape in which the bottom surface of the arm 34b and the concave portions that are open on both the front and rear sides in the rotational direction are formed at a plurality of positions at a predetermined pitch.

  In the first cutter 34, the upper surface of each arm 34 b may be configured as a horizontal surface in accordance with the shape of the bridge 33, but in this example, the upper surface of the outer portion of each arm 34 b is opposite to the bridge 33. A receding surface 34f having a shape receding to the side is formed. Further, the inner side of each arm 34b close to the hub 34a is constituted by a horizontal surface. Thereby, each arm 34b is thinner on the outer side than on the inner side.

  Further, the first cutter 34 is formed with a lightening surface 34g in which the upper portions of the front and rear surfaces in the rotation direction of the arm 34b are inclined to gradually reduce the thickness of the upper portion of the arm 34b. Thereby, the 1st cutter 34 can achieve weight reduction, without reducing the intensity | strength and crushing performance of the arm 34b.

  Further, the first cutter 34 is configured as a curved surface in which the outer peripheral surface of the hub 34a is concavely curved inward, and the hub 34a is thinly formed without reducing the strength of the arm 34b. Is achieved.

  In the first cutter 34, a first shaft portion 34c protruding from the upper surface of the hub 34a is rotatably inserted into the hub 33a of the bridge 33 arranged in the upper stage. In addition, the shaft attachment hole 32e of the uppermost flap 32 is non-rotatably fitted in a portion having a substantially D-shaped cross section on the upper end side of the first shaft portion 34c. Further, a nut 30a is fastened to a screw portion 34h formed at the tip of the first shaft portion 34c, and the flap 32 and the bridge 33 are fixed so as not to be detached from the first cutter 34.

  In the first cutter 34, a second shaft portion 34d protruding from the lower surface of the hub 34a is rotatably inserted into the second cutter 35 disposed in the lower stage. In addition, an angular shaft portion 34i that fits in the third cutter 36 is formed on the lower end side of the second shaft portion 34d. Further, the screw 30b is fastened to the screw hole 34j formed on the bottom surface of the square shaft portion 34i, and the first cutter 34 and the second cutter 35 to which the flap 32 and the bridge 33 are attached are prevented from being detached from the third cutter 36. Fixed to.

  Next, with reference to each figure, the detail of a structure of the 2nd cutter 35 is demonstrated. The second cutter 35 disposed at the lower stage of the first cutter 34 is formed with a hub 35a centering on the rotation axis of the rotary crushing blade, and eight arms 35b extending radially in the tangential direction from the hub 35a are formed by a ring 35c. It is a shape surrounded by.

  The hub 35a of the second cutter 35 is configured so that the inner diameter of the hole into which the second shaft portion 34d of the first cutter 34 is inserted does not become a rotation load of the first cutter 34. It is configured to be larger than the outer diameter.

  Further, the second cutter 35 is formed with leg portions 35d projecting radially from positions at intervals of 180 ° on the outer periphery of the ring 35c. As for the 2nd cutter 35, leg part 35d is engage | inserted by the groove part 31b of the housing 31 shown in FIG. 6, and rotation is controlled. Further, the leg portion 35d has a predetermined height, and the first cutter 34 can be rotated between the bridge 33 and the second cutter 35 by placing the leg portion 33d of the bridge 33 on the upper side of the leg portion 35d. A gap having a predetermined height is formed.

  Of the eight arms 35b, the second cutter 35 has comb teeth 35e formed on the upper surface of the six arms 35b. In the comb tooth portion 35e of the second cutter 35, the convex portion having a shape entering the comb tooth portion 34e of the first cutter 34 is formed at the same pitch as the pitch of the concave portion of the comb tooth portion 34e.

  Since the first cutter 34 and the second cutter 35 are disposed coaxially, the first cutter 34 rotates, and the arm 34b of the first cutter 34 and the arm 35b of the second cutter 35 face each other. The convex comb tooth portion 35e of the second cutter 35 passes between the concave and convex comb tooth portions 34e of the first cutter 34.

  Thereby, the wrinkles that have entered between the arms 35 b of the second cutter 35 are crushed in cooperation with the first cutter 34.

  As described above, since the number of the arms 34b of the first cutter 34 is three and the number of the arms 35b of the second cutter 35 is eight, the distance between the arms 35b is narrower than the distance between the arms 34b.

  For this reason, when the comb teeth 35e are provided on all eight arms 35b by the second cutter 35, the comb teeth 35e of the second cutter 35 are always present between the arms 34b of the first cutter 34. When a block-shaped ridge having a size of 1 is inserted, the heel does not enter between the arms 34b of the first cutter 34, and an event that makes it difficult to be crushed occurs.

  Therefore, in the second cutter 35, among the eight arms 35b, for example, the two arms 35b1 are not provided with the comb tooth portion 35e, so that the second cutter 35 can be rotated during the rotation operation of the first cutter 34. When the arm 35b1 not provided with the comb tooth portion 35e is positioned between the arms 34b of the first cutter 34, a wide space is formed in the circumferential direction.

  As a result, even when a block-shaped wrinkle of a certain size is inserted, a wrinkle enters between the arms 34b of the first cutter 34, and the comb tooth portion 34e and the second cutter 35 are rotated by the rotation operation of the first cutter 34. The coffin is crushed in cooperation with the comb tooth portion 35e.

  In addition, in the second cutter 35, if the number of arms 35b not provided with the comb teeth 35e is large, the crushing ability is reduced. For example, when eight arms 35b are provided, the arm 35b1 not provided with the comb teeth 35e is About two are desirable.

  In addition, the second cutter 35 is configured such that each arm 35b extends radially along the tangential direction of the hub 35a, so that the second cutter 35 has a first cutter with respect to a plurality of comb teeth portions 35e arranged in the radial direction in the second cutter 35. When 34 rotates, the timing which the comb-tooth part 34e of the 1st cutter 34 passes is shifted in the circumferential direction, and the peak of the crushing load is suppressed and the load is flattened.

  Further, the second cutter 35 has pressing surfaces 35f formed on both front and rear surfaces in the rotational direction of the arms 35b. The pressing surface 35f is an inclined surface inclined in a direction in which the upper end protrudes from the lower end on both side surfaces of the arm 35b.

  The third cutter 36 disposed at the lower stage of the second cutter 35 rotates while rubbing against the bottom surface of the arm 35 b of the second cutter 35. For this reason, the pressing surface 35f is formed on both the front and rear side surfaces in the rotation direction of the arm 35b of the second cutter 35, so that the third cutter can be used against the wrinkles crushed to a certain size in contact with the pressing surface 35f. A force for pressing the third cutter 36 can be applied by the rotation operation 36.

  Further, in the second cutter 35, a corrugated surface 35g in which vertical grooves are arranged in parallel is formed on one side of the front and rear in the rotation direction of each arm 35b. Thereby, at the time of the rotation operation of the third cutter 36 in one direction, the second cutter 35 can catch the wrinkles by the concave portion of the corrugated surface 35g and suppress the movement of the wrinkles in the radial direction so that the wrinkles can be reliably crushed. I have to.

  FIG. 10 is an exploded perspective view of a third cutter showing an example of the impact absorbing member. Next, the configuration of the third cutter 36 and the impact absorbing member will be described in detail with reference to the drawings. The third cutter 36 disposed at the lower stage of the second cutter 35 has a disk shape, and a large number of slits 36b are arranged on the entire surface excluding the formation portion of the shaft portion 36a. In the third cutter 36 of this example, a plurality of slit groups are formed, and in each slit group, adjacent slits 36b are arranged substantially in parallel.

  The upper surface of the third cutter 36 is a flat surface and rotates while being in contact with the bottom surface of each arm 35b of the second cutter 35 disposed in the upper stage. Further, the slit 36b of the third cutter 36 penetrates the disk front and back, and an edge is formed at the opening edge of the upper surface side of the slit 36b.

  The wrinkles crushed by the comb teeth portion 34e of the first cutter 34 and the comb teeth portion 35e of the second cutter 35 and dropped on the upper surface of the third cutter 36 are caught by the slit 36b, and the third cutter 36 rotates. The second cutter 35 is pressed against the slit 36b by the pressing surface 35f and is crushed by the edge portion of the slit 36b. The finely crushed soot falls downward through the slit 36b and is discharged to the outside from the drain pipe connection port 21 of the crushing chamber 2 shown in FIG.

  As for the 3rd cutter 36, the square hole part 36c which the square axis part 34i of the 1st cutter 34 fits is formed in the upper surface side of the axial part 36a. Further, a hexagonal hole portion 36d into which the fitting portion 41a of the drive shaft 41 shown in FIG. 1 or the like is fitted is formed on the bottom surface side of the shaft portion 36a, and a screw 30b is provided between the square hole portion 36c and the hexagonal hole portion 36d. A through-hole through which is passed is formed.

  The shaft portion 36a is integrally formed so as to protrude from the bottom surface of the third cutter 36. The shape of the outer peripheral surface of the shaft portion 36a is polygonal, and in this example, it is hexagonal as shown in FIG.

  The shock absorbing member 37 attached to the shaft portion 36a includes a first shock absorbing member 37a and a second shock absorbing member 37b. The first shock absorbing member 37a is made of a resin material having a predetermined hardness. The first shock absorbing member 37a has a cylindrical shape, and a plurality of grooves 37c are formed on the outer peripheral surface. Moreover, the shape of the inner peripheral surface of the first shock absorbing member 37a is a polygonal shape combined with the shape of the outer peripheral surface of the shaft portion 36a, and in this example, it is a hexagonal shape as shown in FIG.

  The second shock absorbing member 37b is made of, for example, a rubber material having a predetermined hardness that is softer than that of the first shock absorbing member 37a. The second shock absorbing member 37b has a circular ring shape on both the outer peripheral surface and the inner peripheral surface, and the diameter of the inner peripheral surface is large enough to be inserted into the shaft portion 36a.

  In the shock absorbing member 37, a screw 38 as a drop-off preventing member is inserted into a long hole 37d formed in the first shock absorbing member 37a, and the screw 38 is fastened to a screw hole 36e formed in the shaft portion 36a. Thus, the shaft portion 36a is fixed.

  FIG. 11 is a side view of an essential part showing an example of the operation of the shock absorbing member. Next, the mounting structure and operation of the shock absorbing member will be described with reference to the drawings. The first shock absorbing member 37a is formed with a long hole 37d extending in the vertical direction penetrating from the outer peripheral surface to the inner peripheral surface. In this example, long holes 37d are formed at two opposing positions of the first shock absorbing member 37a. The dimension in the short direction of the long hole 37d is the length that the head of the screw 38 can enter, and the dimension in the long direction of the long hole 37d is the length that the head of the screw 38 can move.

  In the shock absorbing member 37, the second shock absorbing member 37b and the first shock absorbing member 37a are inserted into the shaft portion 36a with the second shock absorbing member 37b as the upper side of the first shock absorbing member 37a. When the second shock absorbing member 37b and the first shock absorbing member 37a are inserted into the shaft portion 36a, the screw hole 36e formed in the shaft portion 36a is exposed at a predetermined position inside the long hole 37d.

  When the screw 38 inserted into the long hole 37d is fastened to the screw hole 36e, the head of the screw 38 and the upper end of the long hole 37d are positioned at the long hole 37d and the screw hole 36e, as shown in FIG. The positional relationship is in contact.

  Further, in a state where the head of the screw 38 and the upper end of the long hole 37d are in contact with each other, the shock absorbing member 37 is arranged such that the first shock absorbing member 37a protrudes from the lower end 36f of the shaft portion 36a. In particular, the vertical dimension of 37a and the second shock absorbing member 37b is set.

  Thereby, in the shock absorbing member 37, the second shock absorbing member 37b and the first shock absorbing member 37a are inserted into the shaft portion 36a, and the screw 38 is inserted into the elongated hole 37d of the first shock absorbing member 37a. When the screw 38 is fastened to the screw hole 36e of the shaft portion 36a, the first shock absorbing member 37a protrudes from the lower end 36f of the shaft portion 36a and covers the outer periphery of the shaft portion 36a.

  The shock absorbing member 37 is fixed so that the first shock absorbing member 37a can move in the vertical direction along the longitudinal direction of the long hole 37d with respect to the shaft portion 36a. The shock absorbing member 37 is held in a state in which the first shock absorbing member 37a protrudes from the lower end 36f of the shaft portion 36a by the elastic force of the second shock absorbing member 37b in a state where a load in the vertical direction is not applied. .

  When a load in the vertical direction is applied to the shock absorbing member 37, as shown in FIG. 11B, mainly the second shock absorbing member 37b is elastically deformed, and the thickness of the second shock absorbing member 37b is increased. By changing from t1 to t2 (<t1), the first shock absorbing member 37a moves in the vertical direction. At this time, even when the assumed maximum load is applied, the shaft portion 36a of the first shock absorbing member 37a can be held so that the first shock absorbing member 37a can protrude from the lower end 36f of the shaft portion 36a. The protruding height from the lower end 36f, the hardness of the first shock absorbing member 37a and the second shock absorbing member 37b, and the like are set.

  Next, the assembled state of the crushing blade assembly 30 will be described with reference to the drawings. In the crushing blade assembly 30, the hub 35a of the second cutter 35 is rotatably fitted to the second shaft portion 34d of the first cutter 34, and the angular shaft portion 34i of the second shaft portion 34d is connected to the third cutter 36. It fits into the square hole 36c.

  Then, from the hexagonal hole portion 36d side of the third cutter 36, the screw 30b is fastened to the screw hole 34j of the angular shaft portion 34i of the first cutter 34, and the first cutter 34, the second cutter 35, and the third cutter 36 are connected. It is constructed integrally.

  In addition, the hub 33a of the bridge 33 is rotatably fitted to the first shaft portion 34c of the first cutter 34, and the shaft mounting hole 32e of the flap 32 is non-rotatably fitted to the first shaft portion 34c.

  And the nut 30a is fastened by the thread part 34h of the 1st axial part 34c, and the flap 32, the bridge | bridging 33, and the 1st cutter 34 are comprised integrally.

  In addition, the crushing blade assembly 30 integrated as described above is attached to the housing 31 by fitting the leg portion 33d of the bridge 33 and the leg portion 35d of the second cutter 35 into the groove portion 31b of the housing 31 shown in FIG. Thus, the bridge 33 and the second cutter 35 are held by the housing 31 so as not to rotate.

  Then, as shown in FIG. 5, the holding metal fitting 39 is fitted into the groove 31b of the housing 31, and the holding metal fitting 39 is fixed to the housing 31 with a screw 39a. It is held in the housing 31 so that it cannot move. Thereby, the basket 3 in which the flap 32, the first cutter 34, and the third cutter 36 are rotatable with respect to the housing 31 is configured.

<Operation example of the cocoon processing apparatus of the present embodiment>
Next, with reference to each figure, operation | movement of the cocoon processing apparatus 1A of this Embodiment is demonstrated. First, the overall operation of the soot processing apparatus 1A will be described. The lid 12 is opened, soot is introduced into the crushing chamber 2 from the inlet 20, the inlet 20 is closed with the lid 12, and the lid 12 is locked for locking. When rotated in the direction, the control means (not shown) detects that the closing port 20 is closed by the lid 12 and rotates the motor 40.

  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 40 is set so that the flap 32, the first cutter 34, and the third cutter 36, which are rotary crushing blades, rotate at a low speed of about 100 rpm, for example, to suppress the generation of noise and vibration.

  The lid 12 is provided with a water supply hole 12a so that water can be supplied into the crushing chamber 2 even if the inlet 20 is closed with the lid 12, and water is allowed to flow through the sink 100 during crushing processing of the straw. For example, water is supplied into the crushing chamber 2.

  When the motor 40 rotates, the flap 32, the first cutter 34, and the third cutter 36 connected to the drive shaft 41 at the shaft portion 36a rotate integrally. On the other hand, the bridge 33 and the second cutter 35 do not rotate.

  As a result, the soot introduced into the crushing chamber 2 from the inlet 20 is agitated by the agitation arm 32b of the flap 32, roughly crushed in cooperation with the arm 33b of the lower bridge 33, and crushed. The scissors are fed between the arms 34b of the first cutter 34.

  When the scissors fed between the arms 34b of the first cutter 34 pass between the comb teeth 34e of the first cutter 34 and the comb teeth 35e of the lower second cutter 35 due to the rotation of the first cutter 34 It is crushed finely.

  Here, the second cutter 35 is provided with an arm 35b1 that does not have the comb tooth portion 35e among the plurality of arms 35b, so that the arm 35b1 that is not provided with the comb tooth portion 35e is rotated by the rotation of the first cutter 34. When positioned between the arms 34b of the first cutter 34, a large space is formed in the circumferential direction.

  As a result, even a large ridge such as a block shape enters between the arms 34b of the first cutter 34, and the rotation of the first cutter 34 causes the lower second cutter 35 between the comb teeth 34e of the first cutter 34 to move. When the comb tooth portion 35e passes, it is finely crushed.

  Thereby, the combination of a small number of fixed crushing blades and rotary crushing blades can crush the cocoons having various sizes.

  The soot crushed by the cooperation of the first cutter 34 and the second cutter 35 is discharged from the slit 36b by the cooperation of the arms 35b of the second cutter 35 and the third cutter 36.

  That is, when the scissors come into contact with the pressing surface 35f of the arm 35b of the upper second cutter 35 by the rotation of the third cutter 36, the scissors are pressed downward in the direction of the third cutter 36 by the inclination angle of the pressing surface 35f. Receive the power to be.

  As a result, the scissors between the arms 35 b of the second cutter 35 are pressed against the slits 36 b of the third cutter 36 by the pressing surface 35 f of the arm 35 b by the rotation of the third cutter 36. And it crushes by the edge of the upper surface side opening edge part of the slit 36b, is further pushed in by the pressing surface 35f, and falls below through the slit 36b.

  Here, in the scissor processing apparatus 1A, a load applied to each crushing blade is detected by a current value flowing through the motor 40, and a load greater than a predetermined value is applied because the rotary crushing blade cannot rotate during crushing of a hard object. Then, the control to reversely drive the motor 40 is performed, and by changing the direction in which the force is applied, the load is reduced and the hard material can be crushed.

  In the scissor processing apparatus 1A, for example, after the motor 40 is rotationally driven for a certain period of time, a control unit (not shown) stops the driving of the motor 40. The driving time of the motor 40 is set in advance in consideration of the time required for crushing a standard amount of soot introduced into the crushing chamber 2 and discharging it from the drain pipe connection port 21.

  In the soot treating apparatus 1A of the present embodiment, the basket 3 and the inside of the crushing chamber 2 can be cleaned by removing the basket 3. In other words, the handle 32d of the flap 32 disposed at the uppermost stage of the crushing blade assembly 30 is exposed inside the basket 3, and the basket 3 can be easily detached from the crushing chamber 2 by having the handle 32d. Further, when attaching the basket 3 to the crushing chamber 2, it is necessary to fit the hexagonal hole portion 36 d of the third cutter 36 into the fitting portion 41 a of the drive shaft 41. Since the fitting portion 41a and the hexagonal hole portion 36d of the drive shaft 41 are coupled by fitting the square shaft and the square hole, it is necessary to adjust the direction of the hexagonal hole portion 36d.

  In this example, since the flap 32, the first cutter 34, and the third cutter 36 rotate as a unit, the third cutter 36 rotates by rotating the flap 32 with the handle 32d, and the hexagonal hole 36d. The orientation can be adjusted.

  Therefore, when attaching the basket 3 to the crushing chamber 2, the operation of gripping the basket 3 and aligning the direction of the shaft can be performed with the handle 32d of the flap 32, and the operability at the time of attachment / detachment is improved. Safety is improved.

  And since basket 3 can be easily attached or detached with respect to crushing chamber 2, basket 3 can be removed from crushing chamber 2, and crushing blade assembly 30 inside basket 3 or the inside of crushing chamber 2 can be washed.

  Now, as shown in FIG. 4, in the basket 3 removed from the crushing chamber 2, the third cutter 36 is exposed at the bottom of the housing 31, and the shaft portion 36 a protrudes from the bottom. In the basket 3, the outer periphery of the shaft portion 36a is covered with an impact absorbing member 37, and as shown in FIG. 11A, the first impact absorbing member 37a protrudes from the lower end 36f of the shaft portion 36a.

  Thus, when the basket 3 removed from the crushing chamber 2 is placed on the sink 100 with the shaft portion 36a facing down, the first shock absorbing member 37a made of a resin material comes into contact with the sink 100, and the basket 3 The metal portion of the crushing blade that protrudes from the bottom of the sink does not directly contact the sink 100.

  When the sink 100 is made of a metal material such as stainless steel, even if the metal part of the crushing blade is in direct contact, the surface is hardly damaged. On the other hand, there is a kitchen facility in which the sink 100 is made of a resin material such as artificial marble. The sink 100 made of artificial marble has improved texture and image compared to stainless steel or the like. On the other hand, when the metal is in direct contact, the surface is easily scratched.

  In the basket processing apparatus 1A of the present embodiment, even when the basket 3 removed from the crushing chamber 2 is placed on the sink 100 with the shaft portion 36a facing down, the first shock absorbing member 37a made of a resin material is used. Is in contact with the sink 100, and the metal part of the crushing blade does not directly contact the sink 100, so that the sink 100 can be prevented from being damaged.

  Since the housing 31 constituting the basket 3 is made of a resin material, when the basket 3 is placed in the sink 100 by being turned sideways or upside down, the housing 31 made of a resin material is in contact with the sink 100. 100 can be prevented from being damaged.

  If the basket 3 is dropped on the sink 100 with the shaft portion 36a down, the shock absorbing member 37 has a first shock absorbing member 37a protruding from the lower end 36f of the shaft portion 36a. 1 impact-absorbing member 37a collides, and the metal part of the crushing blade does not contact directly.

  When the first impact absorbing member 37a collides with the sink 100, the impact absorbing member 37 receives a load that is pushed upward. When a load in the vertical direction is applied to the shock absorbing member 37, the first shock absorbing member 37a is fixed so as to be movable up and down with respect to the shaft portion 36a by inserting a screw 38 into the elongated hole 37d. 11 (b), the second shock absorbing member 37b is elastically deformed mainly, and the thickness of the second shock absorbing member 37b changes from t1 to t2 (<t1) to absorb the shock. Then, the first shock absorbing member 37a moves upward.

  The first shock absorbing member 37a is made of a softer material than the metal constituting the crushing blade. However, if the entire impact absorbing member 37 is integrally formed of the same material as that of the first impact absorbing member 37a, the amount of elastic deformation when the impact is applied is not sufficient, and the impact cannot be absorbed sufficiently.

  On the other hand, if the entire impact absorbing member 37 is integrally formed of the same rubber material as the second impact absorbing member 37b, the amount of elastic deformation when an impact is applied is large, and the shaft portion 36a is exposed. Furthermore, if the protrusion amount from the lower end 36f of the shaft portion 36a of the shock absorbing member 37 is increased, the shaft portion 36a can be hardly exposed from the shock absorbing member 37, but the shaft portion 36a is a fitting portion of the drive shaft 41. Since it fits with 41a, the amount of projection of the shock absorbing member 37 is limited.

  Therefore, the shock absorbing member 37 includes a first shock absorbing member 37a made of a resin material having a predetermined hardness softer than that of a metal at a portion protruding from the shaft portion 36a, and the first shock absorbing member 37a. Is configured to be movable up and down with respect to the shaft portion 36a. In addition, a second shock absorbing member 37b made of a rubber material having a predetermined hardness softer than the first shock absorbing member 37a is provided on the upper side of the first shock absorbing member 37a. The first shock absorbing member 37a can be moved up and down by elastic deformation of 37b.

  And even when the maximum load assumed when dropping the basket 3 from a predetermined height is applied, the first shock absorbing member 37a can be held so as to protrude from the lower end 36f of the shaft portion 36a. The protruding height of the first shock absorbing member 37a from the lower end 36f of the shaft portion 36a, the hardness of the first shock absorbing member 37a and the second shock absorbing member 37b, and the first shock absorbing member 37a and the second shock. The vertical dimension and the like of the absorbing member 37b are set.

  Thereby, even when the basket 3 is dropped on the sink 100 with the shaft portion 36a facing down, the first shock absorbing member 37a made of a resin material is in contact with the sink 100, and the shock is mainly the second shock absorbing member. Since it is absorbed by the elastic deformation of 37b and the metal part of the crushing blade does not directly contact the sink 100, damage such as cracking of the sink 100 can be prevented.

  When the first shock absorbing member 37a is made of polypropylene (PP) and the second shock absorbing member 37b is made of nitrile rubber (NBR), the first shock absorbing member 37a is separated from the lower end 36f of the shaft portion 36a of the first shock absorbing member 37a. With a configuration in which the protruding height is about 1.5 mm and the vertical dimension of the second shock absorbing member 37b is about 3 mm, the impact value applied to the sink 100 can be reduced by about 40%, and the basket 3 can be reduced from a height of about 50 cm. In the experiment in which the sink was dropped on the sink 100, the sink 100 did not crack and the desired characteristics were obtained.

  The shock absorbing member 37 has a groove portion 37c formed on the outer peripheral surface of the first shock absorbing member 37a so that the first shock absorbing member 37a can be gripped when the basket 3 is removed for cleaning. Thus, it is possible to clean each part and to prevent slipping of the operation of rotating each crushing blade, so that the cleaning work can be performed easily and safely.

  Here, in the scissor treatment apparatus, the arrangement of the rotary crushing blade and the fixed crushing blade is not limited to the example described above, and the fixed crushing blade is arranged at the lowest stage of the basket, and the rotation from the hole of the fixed crushing blade to the upper stage side The structure which the axial part of a crushing blade protrudes may be sufficient. Further, the impact absorbing member 37 may be configured such that the impact can be dispersed by making the lower end of the first impact absorbing member 37a protruding from the shaft portion 36a an uneven shape. Further, the second shock absorbing member 37b may be constituted by a coil spring or a disc spring.

  Further, as the material of the first shock absorbing member 37a, a resin material such as polyethylene (PE), polystyrene (PS), polyphenylene sulfide (PPS) may be used instead of polypropylene (PP). As described above, the material of the first shock absorbing member 37a may be a resin-based material having chemical resistance, and more preferably a material softer than the material constituting the sink 100.

  Further, as the material of the second shock absorbing member 37b, a rubber-based material such as silicon rubber, fluorine sponge, ethylene propylene rubber (EPDM), or butyl rubber may be used instead of nitrile rubber (NBR). As described above, the material of the second shock absorbing member 37b may be a rubber-based material having chemical resistance, and more preferably from the resin-based material constituting the first shock absorbing member 37a. Also, it should be a soft material.

  The present invention is installed in a kitchen or the like of a house and can improve the convenience of garbage disposal.
