Further, the edge blade portion 13b can be formed of a rubber plate, a resin plate, or a metal plate such as stainless steel. According to the edge blade portion 13b, the interval between the inner surface of the drum 40 and the inner surface of the drum 40 can be set appropriately, so that the flow of the blown air is appropriately generated. Because of this, it is configured to be exchangeable.

  Further, according to the present invention, the object to be separated is composed of a content and a storage means for storing the content, and the storage means is a canned can, and the content is a canned content. Also in this case, the separation object can be efficiently drawn into the drum 40, and the processing capacity of the separation device can be improved.

  That is, even if the separation target is a canned product that is difficult to be pulled in, according to the scraping claw according to the present invention, when the canned product is supplied from the input port 40a of the drum 40 into the drum 40, It is possible to prevent the impeller blades 13 constituting the rotary blade portion 12 from repelling and hitting the impeller blades 13 rotating at high speed. Therefore, the cans are efficiently drawn into the drum 40, and the cans are crushed and the cans and their contents can be efficiently separated.

  In this embodiment, as shown in FIGS. 1 and 5 and the like, the foreign matter entanglement preventing structure of the impeller rotating mechanism is provided, so that the inner surface 41a of the side wall 41 and the rotating blade 12 of the impeller 10 , A predetermined interval is generated, and the interval allows the object to be separated to be easily supplied into the drum 40.

  As shown in FIG. 4, the structure for preventing foreign matter entanglement of the impeller rotation mechanism according to the present invention has, as a basic configuration, an impeller blade 13 (see FIG. 8) at a portion excluding both ends 11 a and 11 e (see FIG. 8) of the rotation shaft 11. 5) is fixed, and the impeller 10 includes the rotating blade portion 12, and the device in which the inner side 42 of the rotating blade portion 12 is located and the bearing 50 of the rotating shaft 11 (see FIG. 8). A shaft insertion member 30 fixed to the side wall portion 41 defining the outer side 43, the shaft insertion member 30 being provided to form an insertion hole 31 through which the end 11a of the rotating shaft 11 is inserted; It is provided with.

As shown in FIG. 4, the shaft insertion member 30 has a cylindrical shape in which an insertion hole 31 is formed, and has an outer diameter convexly smaller from the side of the side wall 41 toward the inside 42 of the apparatus. Is formed.
As shown in FIG. 5, the shaft insertion member 30 is provided with flange portions 34, 34 extended on both left and right sides so as to be fixed to the side wall portion 41, and can be fixed with bolts and nuts. , A through hole 35 for attachment.

  As shown in FIG. 4, the impeller 10 is a cylindrical member that is disposed coaxially and fixed to a portion of the end 11 a of the rotating shaft 11 adjacent to the rotating blade 12, The cover ring member 20 is provided with a concave step ring portion 22 formed in a concave step shape that fits so as to cover the shape of the convex step ring portion 32.

  According to the structure for preventing foreign matter entanglement of the impeller rotation mechanism according to the present invention, the convex step ring portion 32 of the shaft insertion member 30 and the concave step ring portion 22 of the covering member 20 of the impeller 10 are in a state of being fitted together. It has a form in which the end 11a of the rotating shaft 11 of the impeller 10 is suitably covered. For this reason, the structure is such that foreign matter is unlikely to enter between the shaft insertion member 30 and the end portion 11a of the rotating shaft 11, so that the foreign matter can be effectively prevented from being entangled, and from the inside 42 of the device to the outside 43 of the device. It is possible to effectively prevent the contents from flowing out.

  The mating relationship between the convex ring portion 32 of the shaft insertion member 30 and the concave ring portion 22 of the cover ring member 20 does not substantially fulfill the function of receiving a load like a bearing. In other words, the design is such that there is a dimension in which a small gap is formed over the entire circumference, and the lubrication is substantially achieved by the oil content of the contents consisting of food waste and garbage to be separated. It is a small gap that does not hinder the rotation of the impeller 10 to the extent that it is sealed in the state.

  As shown in FIGS. 1 and 8, a bearing 50 that receives the end 11 a of the rotating shaft 11 and rotatably holds the impeller 10 is spaced from the shaft insertion member 30 to the outside 43 of the apparatus. Have been. In the present embodiment, the distance between the shaft insertion member 30 and the bearing 50 is wider than the diameter of the circular shaft portion 11c constituting the end portion 11a of the rotating shaft 11, and is 2 times the diameter of the circular shaft portion 11c. The interval is about twice as long.

According to this, the foreign matter entangled with the rotating shaft 11 can be more appropriately prevented from reaching the bearing 50, and the bearing 50 can be prevented from being damaged by the foreign matter.
As shown in FIGS. 4 and 7, the inner peripheral surface 31 a of the insertion hole 31 of the shaft insertion member 30 and the outer peripheral surface 11 d of the circular shaft portion 11 c forming the end 11 a of the rotating shaft 11 have circular shapes. The dimensions are set so that a ring-shaped gap 29 is formed, and the entangled foreign matter can be removed from the circular ring-shaped gap 29 so as to be discharged.

Further, in the present embodiment, the convex ring portion 32 is formed in a plurality of convex ring steps, and the concave ring portion 22 is formed in a plurality of concave ring steps following the shape of the convex ring portion 32. ing.
Specifically, in the present embodiment, the convex stepped ring portion 32 is formed in a two-stage convex ring step shape, and the concave stepped ring portion 22 follows the shape of the convex stepped ring portion 32 and has two concave ring stepped portions. It is formed in a shape.

  More specifically, the shaft insertion member 30 fixed to the side wall portion 41 is formed with a convex step ring portion 32 having a diameter that is reduced stepwise as described above. As shown in FIG. 5, a first fixed ring plane 32a, a first fixed ring peripheral plane 32b, a second fixed ring plane 32c, a second fixed ring peripheral plane 32d, and a third fixed ring plane (circular) A ring end plane 33) is provided. Correspondingly, the covering ring member 20 fixed to the rotating shaft 11 and rotating integrally therewith has a concave step ring portion 22 having a diameter decreasing stepwise toward the rotating blade portion 12. As shown in FIG. 5, the concave stepped ring portion 22 includes a first rotating ring flat surface 22a, a first rotating ring peripheral surface 22b, a second rotating ring flat surface 22c, and a second rotating ring flat surface 22c. It is formed to have a ring peripheral surface 22d and a third rotating ring plane (inner bottom plane 23).

  According to this, since the mating portion between the fixed shaft insertion member 30 and the rotating covering member 20 has a plurality of steps, from the outer peripheral surface of the shaft insertion member 30 and the covering member 20 to the rotating shaft 11. Becomes a long and complicated form as a zigzag path, and a structure in which foreign matters are less likely to enter between the shaft insertion member 30 and the end 11a of the rotating shaft 11 of the impeller 10. I have. That is, since the foreign matter such as the resin bag hardly reaches the rotating shaft 11 and the foreign matter is hardly caught, the foreign matter can be more appropriately prevented from being entangled.

  Further, in the present embodiment, the rotating shaft 11 of the portion where the rotating blade portion 12 of the impeller 10 is provided is a square shaft portion 11b having a square cross section, and the square shaft portion 11b and the four impeller blades 13 ( A, B, C, and D) constitute the rotating blade portion 12. More specifically, with respect to the impeller 10 of the present embodiment, more specifically, on each of four surfaces (four long planes) constituting the outer surface of the square shaft portion 11b having a square cross section formed in a square rod shape, In a form in which flat portions on the base side of the blade base portion 13a constituting the base of each plate-shaped impeller blade 13 (long flat portions corresponding to the four outer surfaces of the square shaft portion 11b) are in contact with each other, It is formed by welding.

According to this, the impeller 10 that functions to crush the object to be separated and appropriately separate by the blowing effect of the air can be manufactured with high workability so as to have high accuracy and high strength. As shown in FIGS. 1 and 8, reference numeral 14 denotes a reinforcing plate, which is provided so as to reinforce the impeller blade 13 and generate air. Reference numeral 60 denotes a drive unit which is provided so as to rotate the impeller 10, and is constituted by, for example, a drive motor (not shown) and a power transmission device using a V-belt as in the present embodiment. I have.
The principle, configuration, and operation and effect of separating the separation object into the contents and the storage means according to the separation apparatus including the impeller 10 are the same as those in the related art, and a description thereof will be omitted.

  In this embodiment, a portion of the covering member 20 adjacent to the rotary blade 12 is provided in a square hole 21 to which the square shaft portion 11b is fitted and fixed. An extended portion of the square shaft portion 11b is provided so as to be fitted to a halfway portion of the hole 21 in the axial direction, and at least a square hole 21 in a portion from the square shaft portion to the end of the rotary shaft 11 is provided. With respect to the portion where the shaft portion 11b is not fitted, a circular shaft portion 11c having a circular cross section and a diameter smaller than the length of one side of the square hole 21 is provided as a portion extending from the square shaft portion.

  An inner bottom surface 23 of the concave stepped ring portion in which the square hole 21 of the covering member 20 is opened is constituted by four planes formed by being surrounded by an arc and a chord. A circular ring end plane 33, which is provided as a cutting edge portion 24 (see FIG. 6) formed in a shape and is a plane of the convex tip of the convex step ring portion 32 of the shaft insertion member 30, is a receiving blade portion for the cutting edge portion 24. 33 (see FIG. 7).

  According to this, the foreign matter can be suitably cut by the cutting blade part 24 rotating while being in contact with the fixed receiving blade part 33. That is, according to the cutting blade portion 24 and the receiving blade portion 33, if a foreign matter such as a resin bag is easily entangled, the convex step, which is a joining portion between the fixed shaft insertion member 30 and the rotating covering member 20, is used. Even in the case of entering through the fitting portion of the ring portion 32 and the concave step ring portion 22 and trying to reach the rotating shaft 11, the entering foreign matter can be appropriately cut. The cut foreign matter is discharged from the circular ring-shaped gap 29. Therefore, it is possible to more effectively prevent the entering foreign matter from becoming entangled with the rotating shaft 11.

  The embodiment shown in FIG. 8 is a separation device using the above-described structure for preventing foreign matter entanglement of the impeller rotation mechanism. The inside 42 of the device is inside the drum 40 of the separation device, and the outside 43 is the drum 40 And the impeller 10 is provided such that the rotating shaft 11 is arranged horizontally and rotates.

  On the upper side of one end face of the drum 40, the separation target is related to the axial extension direction of the rotary shaft 11 in the rotary blade portion 12 so that the separation target is crushed and separated by the impeller 10. An insertion port 40a is provided so as to be inserted into the one end upper side 12a, and the shaft insertion member 30 is provided on a side wall 41 provided on one end surface of the drum 40 provided with the insertion port 40a. By being arranged, the separation device is suitably configured.

Further, as one embodiment, the object to be separated is composed of a content and a storage means for storing the content, the storage means is a resin bag or a resin container, and the content is a resin bag or a resin bag. Even in the case where the contents are contained in a resin container, it is possible to more effectively prevent a foreign substance of a resin material such as a resin bag from being entangled with the rotating shaft 11 of the impeller 10.
Therefore, according to this, the foreign material of the resin material is entangled with the rotating shaft 11 itself, or the foreign material is melted by friction and adheres to the rotating shaft 11, thereby adversely affecting the rotation of the impeller. For example, it is possible to prevent an increase in power consumption of the motor or damage to the device.

In addition, the resin bag and the resin container include bags containing general garbage and combustible garbage, and resin material containers including a plastic packaging material used as a food package and a plastic bottle containing a liquid. The whole thing formed with resin material is included.
However, the storage means for the object to be separated is not limited to the resin bag or the resin container as in the above-described embodiment, but includes metal objects such as steel or aluminum such as canned cans, and the object to be separated. As an example, an object including paper, for example, a gypsum board is also included.
That is, according to the separation device of the present invention, the packaged food waste can be efficiently separated into the organic material and the like contained therein and the waste plastic and metal without the foreign matter being entangled with the rotating shaft 11.・ Can be separated.

  In the separation device of the embodiment shown in FIG. 8, the contents composed of crushed food waste and the like are discharged downward from a porous portion provided at the lower part of the drum 40, and are stored in a storage means such as a resin bag. An object is discharged to the side from the upper side of the downstream side of the drum 40 in the blowing direction. The principle, configuration, and operation and effect are the same as those of the conventional separation device, and the description is omitted.

Further, the structure for preventing foreign matter entanglement of the impeller rotation mechanism according to the present invention may be provided only on one end 11a of the rotating shaft 11 where the phenomenon that foreign matter is substantially entangled occurs as in the present embodiment. Although it is good, it is needless to say that both ends 11a and 11e of the rotating shaft 11 may be provided.
Since the other end 11e of the rotating shaft 11 of the present embodiment is located before the position of the drum from which the object to be separated is separated / sorted and discharged, the possibility of foreign matter being entangled is low. Also, there is a low possibility that separated matter such as organic matter overflows. As shown in FIG. 8, the cylindrical shaft insertion member 36 fixed to the other end face of the drum 40 is used. , Are inserted in a loose fit state. The cylindrical shaft insertion member 36 is provided with a diameter-reduced portion at a position halfway in the axial direction of the insertion hole, and the step forming the diameter-reduced portion prevents outflow of contents. It has a structure.

  Furthermore, the foreign matter entanglement prevention structure of the impeller rotation mechanism according to the present invention is not limited to being appropriately used for the separation device as described above, but may be a crushing device, a washing device, a mixing device, or a stirring device. In addition, the configuration is suitably used.

  As described above, the present invention has been described in various forms with reference to preferred embodiments. However, the present invention is not limited to the embodiments, and it is needless to say that many modifications can be made without departing from the spirit of the invention. That is.
