Description

  The present invention relates to a bone crushing apparatus capable of crushing human or animal bones sequentially.

  In general, burned bones (remains) of people such as pets or animals cremated in crematoriums are buried in graves such as temples or stored in an ossuary.

  The amount of bone to be picked up at the crematorium varies depending on local customs and crematorium systems, but it is generally said that all bones are picked up in eastern Japan and partial bones are picked up in western Japan. The amount may exceed 2 kg for an adult male (see Non-Patent Document 1 below). Further, when not picking up the whole bone, a lot of burned bones (bones) and bone ash that have not been picked up are taken up by a specific contractor and disposed of as bone ash in the same manner as general incineration garbage ash. For the bereaved family, it is thought that the deceased's remains are treated as garbage.

  Ashes are crushed into granules or powders with a particle size of about 1 to 2 mm or less (hereinafter, the terms “grain” and “powder” are treated synonymously), the bulk capacity is reduced to less than half. It is convenient for handling when splitting or splitting. In recent years, an increasing number of people desire natural burial that powders remains and scatters them into the sea or mountains. In this case, in order to pulverize ashes by hand, tools such as a mortar and pestle or hammer are used to grind or crush the remains and pulverize them. Is time consuming and labor intensive, and is difficult to make into a fine homogeneous powder. Also, some bereaved people may feel resistance to crushing the deceased's remains by hand.

  Therefore, a bone crushing device has been developed that mechanically pulverizes remains as mechanically (see, for example, Patent Document 1 below). In addition, there is a trader who carries out powdering of remains as a substitute for the bereaved family (for example, see Non-Patent Document 1 below).

JP 2005-40684 A “We will make the remains into a powder of 1 mm or less.”, [Online], Aoi Tsuzuki, [Search August 24, 2008], Internet <URL: http://www.saigetuan.com/powder/ powder.pdf>

  Depending on the bereaved family, even though the crushing of the remains is considered a solemn one and mechanically processed, the bereaved family crushes the remains in the presence of a priest, reducing the spiritual burden of the bereaved. However, there are cases where it is desired to be able to feed the deceased and to obtain benefits (such as a reduction in bulk capacity) from powdering of remains.

  However, in general, when asking a contractor to grind the remains, the bereaved family is processed without being present, and thus there is a problem that the remains cannot be grinded while apologizing for the deceased. Further, the bone crushing device exemplified in Patent Document 1 includes an occlusion container, a rotary body provided in the occlusion container so as to be capable of high-speed rotation, drive means for driving the rotary body to rotate at high speed, and the inside of the occlusion container. In the case of having a repeated collision means for repeatedly colliding the bone thrown into the rotating body, when all the remains to be crushed are put into the closed container or crushed in several times Each time, it takes time and effort to take out the processed crushed remains and to insert new crushed remains.

  Therefore, if there is a bone crushing device that can crush while ascending the remains, the priest and the priests will be devout, and regardless of the number of remains, crushing slowly while putting the remains one by one Can do. That is, the bereavement process can be performed while the bereaved family apologizes to the deceased.

  However, as a result of intensive studies by the inventor of the present application, when a remains opening is simply provided to the closed container of the bone crushing apparatus exemplified in Patent Document 1 and the remains are inserted during the grinding process, A problem arises in that fine powder of treated ashes (particularly fine powder of powdered ashes) gushes out of the mouth. Therefore, when an exhaust port for forcibly exhausting the fine powder etc. of the remains is provided in the closed container and discharged to the outside, if the bone crushing device is installed indoors such as in the temple hall and the remains are crushed This is not preferable in terms of appearance because a long exhaust duct is provided at the exhaust port and the inside of the hall is moved. In addition, instead of providing an exhaust duct, it may be possible to provide a filter that removes fine powder from the remains at the exhaust port provided in the closed vessel and filters it. Clogged, and fine powder of the treated ashes will be ejected in a smoke form from the inlet.

  In addition, the inventor of the present application provides an outlet for discharging the powdered remains in the closed container, and communicates between the container for recovering the powdered remains and the outlet with a cylindrical filter material, and exhausts from the outlet. Although we tried very hard to filter the fine powder produced, the same clogging problem occurred, and in order to secure a large filter area, it was necessary to enlarge the cylindrical filter material. The resulting and treated fine powder of ashes was not a sufficient solution to erupt into smoke.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a bone crushing device that can be crushed while sequentially putting the remains, and that the fine powder of the crushed remains is not ejected in the form of smoke. The bereaved family is able to crush the remains of the remains even inside the temple hall.

  In order to achieve the above object, a bone crushing apparatus according to the present invention is a bone crushing apparatus capable of crushing while sequentially inserting human or animal bones, and rotates at high speed in a bone crushing space formed therein. A crushing operation unit that crushes the bone by colliding with a rigid body, a bone introduction unit that introduces the bone before crushing into the bone crushing space via an inlet of the crushing operation unit, and a crushing operation unit An accommodating portion for accommodating granular or powdered fine bone pulverized in the bone pulverizing space discharged from the outlet, a discharge path communicating between the pulverizing operation portion and the accommodating portion, the accommodating portion, and the discharging A path or a tubular return path communicating from the exit of the crushing operation unit to the bone introduction unit or the entrance of the crushing operation unit is provided, and passes through the bone crushing space during the crushing operation of the crushing operation unit Through the return path, The first feature to be circulated from the outlet of the serial crushing operation unit to the inlet of the grinding operation unit.

  According to the bone crushing device of the first feature, when the bone before pulverization is thrown into the bone introduction unit, the bone introduced into the bone pulverization space via the entrance of the pulverization operation unit is within the bone pulverization space. The fine bone that collides with the rotating rigid body that rotates at high speed and is pulverized and pulverized, is discharged from the outlet of the pulverization operation unit to the storage unit and stored. Here, the fine powder of bone generated by the pulverization process in the bone pulverization space circulates on the airflow that circulates from the exit of the pulverization operation unit generated during the pulverization operation to the inlet of the pulverization operation unit via the return path For this reason, it is prevented that the smoke is ejected outside the bone crusher. As a result, the bone crushing apparatus can be freely installed indoors, such as in a temple hall, and the bereaved family can slowly perform the remains crushing process in a quiet atmosphere while the deceased apologizes to the deceased.

  Furthermore, since the bone crushing device of this feature is a bone crushing device that can crush while sequentially inserting bones, the crushing operation unit, which is the main mechanism part, can be used for images related to religions such as Buddhism as described later. When housed inside, the bone crushing process can be sequentially performed in a state where the crushing operation unit is housed in the image, and the crushing operation unit is disassembled to collect the fine bone crushed from within the bone crushing space. There is no need to do.

  In addition to the first feature, the bone crushing device according to the present invention further includes the crushing operation through the bone crushing space from the entrance of the crushing operation unit by the rotation of the rotating rigid body of the crushing operation unit. The second feature is that an airflow that escapes to the outlet of the section is generated.

  According to the bone crushing device of the second feature, since a circulating airflow is generated by the rotation of the rotating rigid body, it is not necessary to separately provide a mechanism for generating the circulating airflow, and the configuration of the bone crushing device can be simplified. .

  In the bone crushing device according to the present invention, in addition to the first or second feature, the crushing operation unit is provided on a housing that forms the bone crushing space inside, and a wall surface of the housing. Two openings for the inlet and the outlet, a rotating disk housed in the bone crushing space, and a rotating body made of one or a plurality of rod-shaped bodies protruding eccentrically from the rotating shaft from the rotating disk, A perforated plate having a plurality of through-holes having a diameter within a set range of the fine bone particle diameter that covers the outlet opening, provided outside the housing, and the tip of the rotating shaft is inserted into the bone grinding space A third feature of the present invention is that it includes a rotary drive connected to the rotary disk.

  According to the bone pulverizing device of the third feature, the pulverization operation unit of the bone pulverizing device of the first feature configuration is specifically configured. More specifically, since one or a plurality of rod-shaped bodies protrude from the rotating disk eccentrically with respect to the rotation axis, the one or more rod-shaped bodies move within the bone grinding space with a predetermined rotation radius around the rotation axis. Since it rotates and moves at a high speed, the bone before crushing introduced from the opening for entrance collides with the rotating rod-shaped body and is crushed in the bone crushing space formed inside the housing. At the same time, the crushed pieces further collide with the inner wall of the casing and are pulverized, collide with the rod-like body that rebounds and moves again, and are further finely pulverized. Become. Here, since the diameter of the through hole of the perforated plate provided so as to cover the opening for the outlet is within the setting range of the particle size of the fine bone, the bone larger than the diameter of the through hole is transferred from the outlet to the accommodating part. Is not ejected and rebounds on the surface of the perforated plate, and is crushed again until it becomes smaller than the diameter of the through hole in the bone crushing space, and only the fine bone crushed smaller than the diameter of the through hole passes through the through hole of the perforated plate. It passes through and is discharged from the outlet to the accommodating portion. As a result, fine bones having a uniform particle size are accommodated in the accommodating portion.

  In addition to the third feature, the bone crushing device according to the present invention further includes an opening for the entrance sandwiching the wall surface of the housing to which the rotary driving machine is attached and the rotary disc. A fourth feature is that the outlet opening is provided on the rotation axis of the opposite wall surface, and the outlet opening is provided on the bottom wall surface of the casing.

  According to the bone crushing device of the fourth feature, the bone before crushing is thrown into the space surrounded by the movement trajectory of the rod-like body that rotates at high speed, and the thrown bone falls and collides with the rod-like body. Then, the crushed pieces are further dropped and discharged from the outlet opening provided on the bottom wall surface of the housing, and therefore, it is possible to effectively suppress the crushed pieces from flowing back and jumping out from the inlet opening. Also, even if some of the crushed pieces flow backward from the inlet opening and pop out, if the bone introduction part is installed upward from the inlet opening, the crushed pieces popped out due to gravity will remain in the bone crushing space. Is re-entered.

  The bone crushing apparatus according to the present invention is further characterized in that, in addition to the third or fourth feature, the cross-sectional shape perpendicular to the longitudinal direction of the rod-like body of the rotating body is a wedge shape. .

  According to the bone crushing device of the fifth feature, the rod-like body works as a rotary blade, and the crushing operation unit operates as a blower. From the exit of the crushing operation unit to the inlet of the crushing operation unit via the return path. A circulating airflow is generated, and it becomes possible to efficiently confine the fine bone powder generated by the grinding treatment in the bone grinding space in the circulating airflow.

  In addition to any of the above features, the bone crushing apparatus according to the present invention further includes that at least a part of the discharge path is configured by a fine filter cloth that does not allow the fine bone fine powder to pass through. The sixth feature.

  According to the bone pulverizing apparatus of the sixth feature, even if the exhaust pressure from the outlet of the pulverization operation unit to the inlet of the pulverization operation unit via the return path temporarily increases, the filter cloth in the discharge channel is passed through. The exhaust pressure can be adjusted by releasing the exhaust gas to the atmosphere, so that the fine bone fine powder can be prevented from flowing back from the inlet of the crushing operation portion to the bone introduction portion.

  In addition to any one of the above features, the bone crushing device according to the present invention further includes an axial direction toward the bone introduction portion of the return path at the junction of the tip of the return path and the bone introduction portion, and the A seventh feature is that an axial direction toward an entrance of the crushing operation portion of the duct forming the bone introduction portion intersects at an acute angle.

  According to the bone crushing device of the seventh feature, a smooth air flow is generated from the tip of the return path to the back of the bone introduction section at the junction of the tip of the return path and the bone introduction section. Therefore, it is possible to prevent the fine powder confined in the circulating airflow from flowing backward from the junction to the entrance of the bone introduction portion and being released to the outside.

  In addition to any one of the above features, the bone crushing device according to the present invention is an image in which at least the crushing operation unit, a part of the bone introduction unit, and a part of the discharge path are related to religion such as Buddhism. It is the 8th characteristic that it is accommodated in the inside.

  According to the bone crushing device of the eighth feature, since the mechanical part of the bone crushing device is not exposed to the outside and is housed inside an image related to religion such as Buddhism, It becomes possible to carry out more suitably as a typical act. In addition, since the mechanical portion of the bone crushing device, particularly the crushing operation unit, is housed inside the image, noise and vibration generated in the crushing operation unit can be absorbed inside the image to reduce noise or vibration. it can.

  In the eighth aspect, more preferably, the housing portion is detachably provided on the lower surface side of the top plate of the table on which the image is placed. As a result, it is possible to easily collect the pulverized fine bones by removing only the housing part from the stage on which the image is placed without removing the main mechanism part including the pulverizing operation part of the bone pulverizing apparatus from the inside of the image.

Bolts are passed through the other two openings provided in the lid 32, the disk 33, and the top plate 71, and the lid 32 and the disk are fixed to the lower side of the top plate 71. By setting the return path 50 as described above, the exit 13 is exited from the bone crushing space 11, and the discharge path 40, the upper portion of the accommodating portion 30, the return path 50, the connection port 21c, and the introduction pipe 22 are passed through. A circulation path returning to the inlet 12 is formed, and an air flow generated by the two first rod-like bodies 15b rotating in the bone crushing space 11 circulates in the circulation path. For this reason, the fine powder of bone finer than the fine bone generated in the bone crushing space 11 is not circulated in the circulation path and ejected outside through the circulating airflow. In the present embodiment, the flexible hose 51 of the return path 50 is installed so that it is not conspicuous on the back side where the survivors of the figurine 60 do not face.

  Further, in the present embodiment, as shown in FIG. 5, the connection port 21 c of the return path 50 is connected to the connection port 21 c (a junction point) where the tip of the return path 50 (flexible hose 51) and the receiving portion 21 connect. The axial direction toward the center and the axial direction (downward) toward the inlet 12 of the crushing operation portion 10 of the lower pipe of the receiving portion 21 intersect each other at an acute angle α (about 35 ° in this embodiment). Thereby, circulation of the air current in the circulation path is performed more smoothly. Further, the bottom of the saucer is also provided on the saucer side from the connection port 21c (joint location) of the receiving part 21 by the airflow smoothly injected from the tip of the return path 50 to the downstream side of the lower pipe of the receiving part 21 at the joining point. Since an air flow directed from the opening side toward the joining location is induced, the fine powder circulating on the air flow in the circulation path flows backward from the joining location to the receiving portion 21 side of the bone introduction portion 20. Therefore, it is not ejected to the outside and is confined in the airflow in the circulation path.

  Next, a process for crushing the remains using the bone crusher 1 of the present embodiment will be described. In addition, the following description demonstrates one usage pattern of the bone crushing apparatus 1, and is not necessarily limited to the said usage pattern.

  First, the bone crushing device 1 partially housed in the white elephant figurine 60 placed on the table 70 is assembled as shown in FIG. 1 and installed indoors such as in a temple hall. The power cord of the electric motor 17 is connected to an AC outlet of a commercial AC power source, and the electric motor 17 is activated. While listening to the accompanying priest's reading or music for the deceased, the bereaved family or priest throws one or several remains into the receiving part 21. The input ashes (bones before pulverization) pass through the introduction tube 22 and are input from the inlet 12 into the bone pulverization space 11 of the pulverization operation unit 10. The remains put in the bone crushing space 11 fall downward in the space surrounded by the movement trajectories of the two first rods 15b that rotate in the bone crushing space 11, and rotate at high speed. It collides with the two first rods 15b to be pulverized. The crushed pieces of bone collide with the two first rods 15b that rotate and move again at high speed by colliding with the inner wall of the casing 14 or the perforated plate 16 and partially pulverizing or rebounding. It is crushed. By repeating these collisions, the remains put in the bone crushing space 11 are gradually crushed and finally become finer bone than the through holes of the perforated plate 16. Pass and fall. The dropped fine bone passes through the discharge path 40 and is collected in the container 31 of the storage unit 30.

  On the other hand, the two first rod-like bodies 15b that rotate and move at a high speed with the start of the electric motor 17 generate an air flow from the inside to the outside of the rotation trajectory of the first rod-like body 15b. The air sucked in is discharged from the outlet 13, and a circulation path for airflow returning to the inlet 12 is formed via the discharge path 40, the return path 50, and the introduction pipe 22. Therefore, fine powder of bone that is finer than the fine bone generated in the bone grinding space 11 by the above-mentioned grinding process of the remains can be circulated in the circulation path and ejected to the outside on the circulating airflow. Absent. Therefore, the remains can be crushed without being bothered by the fine powder of bone ejected to the outside.

  In the present embodiment, since the middle portion of the discharge path 40 is configured by the air-permeable filter cloth 42, the exhaust pressure in the discharge path 40 is automatically adjusted. Here, since the filter cloth 42 has a large number of micropores that do not allow bone fine powder to pass therethrough, leakage of the bone fine powder to the outside through the filter cloth 42 is suppressed. Immediately after the start, since there is not enough airflow circulating in the circulation path, the initial fine powder of bone or the fine powder of bone already attached to the fibers of the filter cloth 42 is temporarily removed. However, even if the temporary bone fine powder cannot be completely prevented from leaking to the outside, there is no problem in practical use. Therefore, it is sufficient for the filter cloth 42 to be able to suppress leakage of fine bone powder to the outside during the steady operation of the ashes of the remains.

  When the ashes are crushed, the operation of the electric motor 17 is stopped, the container 31 is removed from the lid 32, and the powdered fine bone collected therein is separately prepared in a container such as an urn or a bag for scatter. Transfer.

  In the present embodiment, as shown in FIG. 1, the bone crushing apparatus 1 includes a crushing operation unit 10, an introduction tube 22 of the bone introduction unit 20, and a receiving port 41 of the discharge path 40. The lid 32 of the accommodating portion 30 is fixed to the back surface of the top plate 71 of the base 70, and the filter cloth 42 in the middle portion of the discharge path 40 is accommodated in the receiving port 41 when not in use. Is invisible or difficult to see. Moreover, the receiving part 21 of the bone introduction part 20 and the flexible hose 51 of the return path 50 which are other components can be removed from the main body part of the bone crushing apparatus 1 when not in use. Accordingly, when the remains are not used after the grinding of the remains, the filter cloth 42 is stored in the receptacle 41, the receiving portion 21 and the flexible hose 51 are removed, and the figurine 60 after the receiving portion 21 is removed. By placing a lid or another image on the upper opening 61, the white elephant figurine 60 can be used as an ornamental or festival figurine when not in use. In addition, as shown in FIG. 6, another image placed on the upper opening 61 is a Hanamido 63 with a Buddha birth Buddha (not shown) inside, which is used for flower festival events and legal stories.
