Description

  The present invention relates to a bone crushing apparatus that crushes human bones, animal remains, and the like into powder and a bone crushing method for crushing crushed bone using the same.

  Traditionally, in order to mourn the spirit of the deceased, the remains of the cremations are stored in the urn, and the urn is stored in a cemetery or ossuary and is provided by the bereaved family.

  On the other hand, in recent years, it has become a social situation where it is difficult to maintain the grave due to the disappearance of the ancestry due to the collapse of the “family” system, the nuclear family, the declining birthrate, etc. . Furthermore, in large metropolitan areas, due to soaring land prices, it is economically difficult to construct a grave even if you want to construct one.

  In addition, due to the diversification of the view of life and death, an increasing number of people wish to scatter the ashes in places (sea, mountains, etc.) that are related to the deceased without burying the cremation bones. In the case of bone loss, the remains must be crushed to a size that cannot be determined as human bones (powder of 2 to 3 mm or less, preferably 1 mm or less). A bone crusher for crushing is disclosed.

  When the remains are crushed for crushed bones, there are no sanitary problems as long as they are immediately after cremation. However, there are cases where the remains once buried in the cemetery are subsequently scattered depending on the circumstances of the bereaved family. If you remove bones that have been buried in a dark underground room with moisture like a cemetery for a long time and scatter them, the sanitary condition of the remains deteriorates, such as mold attached to the remains or the growth of bacteria. There is a possibility. When bones that have been powdered in such a state are scattered, mold and bacteria may scatter, which may cause health damage to the human body and may cause environmental deterioration of the scattered places.

  Therefore, an object of the present invention is to provide a bone crushing apparatus that crushes remains as a sufficient hygiene condition.

  To achieve the above object, the bone crushing apparatus of the present invention comprises a heating means for heating the bone, a crushing means for crushing the bone heated by the heating means, and a bone crushed by the crushing means in a finer powder form. And crushing means for crushing.

  Preferably, the heating means supplies heated hot air to the bone, and the crushing means crushes the bone heated by the heating means to a size that can pass through the inlet of the crushing means.

  For example, in the above-described bone crushing apparatus of the present invention, the crushing means is provided below the heating means, the crushing means is provided below the crushing means, and the bone placed on the crushing means is operated without operating the crushing means. After heating by the heating means from above, the crushing means is operated to crush the bone, and the bone crushed by the crushing means is dropped onto the crushing means and crushed.

  Alternatively, in the bone crushing apparatus of the present invention, the crushing means is provided at the lower part of the heating means, the bone heated by the heating means falls to the crushing means and is crushed, and the crushing means is provided at the lower part of the crushing means, The bone crushed by the crushing means falls to the crushing means and is crushed.

  According to the bone crushing apparatus of the present invention, the remains to be crushed can be sterilized and dried by heating, and hygienic bone can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. However, this embodiment does not limit the technical scope of the present invention.

  1 and 2 are diagrams showing a configuration example of a bone crushing apparatus according to an embodiment of the present invention. FIG. 1 is a front view of the bone crushing apparatus, and FIG. 2 is a side view of the bone crushing apparatus.

  The bone crusher is covered with a box 12 with casters 10 attached. The box 12 can be formed of various materials such as metals such as aluminum and stainless steel, wooden or plastic resin, and the outer surface of the box 12 may be decorated suitable for a funeral. On the upper surface of the box body 12, an openable / closable opening 14 for inserting a remains is provided. The bone crushing apparatus includes a tray part 16 that accommodates the remains put in from the opening 14, a heating part 18 that heats the remains of the dish part 16 for sterilization, and an air compressor 20 that generates compressed air.

  The heating unit 18 is a heater gun that sends out heated air (hot air), for example, and heats the compressed air generated by the air compressor 20 with a heater (for example, about 800 W) from the tip to the remains on the tray 16. Release towards. The remains on the tray 16 are sufficiently sterilized and dried by heating. The heating temperature is, for example, about 400 ° C. The heating time is appropriately determined according to the amount of remains and the storage state. The heating time is set by operating the operation panel 22 by the operator. By applying the hot air to the bone, the heating time for sterilization / drying can be shortened as compared with the case of simply heating with a heater.

  The operation panel 22 sends an instruction signal to the control unit 40. The control unit 40 controls the operation of each unit of the bone crusher according to various instruction signals input from the operation panel 22, and preferably executes control by a computer.

  A crushing portion 24 is provided at the lower portion of the tray portion 16. The crushing portion 24 is formed so that the two crushing rotary blades 24 a and 24 b mesh with each other, and is driven to rotate by a gear motor 26. The bottom surface of the saucer portion 16 is omitted, and the crushing rotary blades 24 a and 24 b substantially form the bottom portion of the saucer portion 16. That is, since the crushing rotary blades 14 a and 24 b serve as the bottom of the saucer part 16, the bone on the saucer part 16 is substantially synonymous with the bone placed on the crushing part 14. The remains put in the tray 16 are heated and dried on the crushing rotary blades 24a and 24b. With this configuration, the height of the entire apparatus can be suppressed, which contributes to downsizing of the apparatus. During heating by the heating unit 18, the crushing rotary blades 24a and 24b are not rotated. The heating time is set as a timer, and when the timer time expires, the remains are crushed by rotating the crushing rotary blades 24a and 4b.

  In the present embodiment, the configuration example in which the crushing rotary blades 14a and 24b serve as the bottom portion of the tray portion 16 is shown, but the configuration is not limited thereto. For example, the saucer part 16 includes a bottom part configured to be openable and closable. After being heated and sterilized by the heating part 16 for a predetermined time, the sterilized remains are crushed and rotated by opening the bottom part of the saucer part 16. You may make it fall on the blades 24a and 24b. The heating time is set as a timer, and when the timer time expires, the bottom surface of the saucer portion 16 opens downward, for example, like a double door, and the remains fall to the crushing portion 24.

  The crushing rotary blades 24a and 24b rotate in opposite directions so as to guide the remains to the meshing part of the crushing rotary blade (see arrows), and crush the remains at the meshing part. By the crushing part 24, the remains are crushed so that one side is, for example, about 15 mm or less. In the crushing part 24, the remains should be crushed to a size that can pass through the inlet of the crushing part 30 provided below.

  The remains crushed by the crushing unit 24 fall from the meshed portions of the rotary blades 24a and 24b, and are guided to the input port of the crushing unit 30 via the pyramid-shaped accumulating unit 28 that receives them.

  The crushing unit 30 crushes the remains crushed by the crushing unit 24 into powder. Various kinds of known pulverizers can be adopted as the pulverization unit 30, but an impact type pulverizer (so-called hammer crusher) having a rotary striking member is preferable. The impact-type pulverizer, for example, rotates a rotor (rotor) having a hammer (hammer) attached to its outer periphery at high speed in a cylindrical pulverization chamber and puts it into a pulverization chamber (this embodiment) In this case, the remains are crushed by a crushing operation by impact force such as hammering and collision with the inner wall of the crushing chamber.

  A mesh screen is disposed in the passage to the discharge port in the crushing unit 30, and the material that has passed through the mesh screen is discharged and collected as powder. The particle size of the powder can be adjusted by adjusting the mesh size of the mesh screen. If moisture remains in the remains, clogging may occur, but clogging can be prevented by sufficiently drying by the heating unit 18 before crushing.

  In the present embodiment, a hammer crusher (model NH-34) manufactured by Sansho Industry Co., Ltd. is used as the pulverizing unit 30. The bone crusher can be downsized to a desktop level. When the hammer crusher is used, the size of the box 12 can be reduced to a height of about 1200 mm × width of 600 mm × depth of 680 mm, which contributes to space saving.

  A collection bag (not shown) is attached to the lower discharge port 32 of the pulverization unit 30, and powdered remains discharged from the lower discharge port 32 are collected by the collection bag. Although the upper outlet is an air vent, a collection bag is attached in the same manner as the lower outlet 32.

  A door or a drawer (not shown) is provided on the side surface of the box body 12, and the powdered remains collected in the collection bag are taken out therefrom. Then, the bone that has been pulverized using the bone pulverizing apparatus of the present embodiment is scattered.

  In this way, the bone crushing apparatus in the present embodiment can pulverize the remains as a powder so as to be suitable for scatter. Since the remains are sufficiently heated and sterilized, there is no concern about damage to human health or environmental degradation even if they are broken. In addition, the remains may be scattered and partly stored in a dedicated urn for preservation at an ossuary or at home. By making the remains into a powder, the remains can be stored in a smaller-capacity container (container), and the storage space can be saved.

  As described above, the bone crushing apparatus according to the present embodiment has a three-stage vertical structure in which the heating unit 16, the crushing unit 24, and the crushing unit 30 are provided in the vertical direction. Since it is a structure that performs the next processing while dropping downward, the remains processed in each part can be automatically sent to the next processing, and it has a simple and ultra-compact configuration of a desktop type. be able to.

  In addition, the bone crushing apparatus of this Embodiment is applicable not only to a human bone but animal bones, such as a pet.
