Description

Technical Field

[0001] This application relates to the field of funeral services, and in particular to a bone crusher. Background Technology

[0002] In the funeral industry, workers first cremate the body. After cremation, a lot of bones remain, which then need to be manually broken into granular and blocky ash, which is then placed in an urn. The process of breaking the bones is labor-intensive and has a low degree of automation. In addition, since the bones have just been cremated, there is a lot of ash on the surface, which generates a lot of dust during the actual breaking process, causing some pollution to the environment. Summary of the Invention

[0003] In order to improve the automation level of bone crushing and reduce environmental pollution during the crushing process, this application provides a bone crusher.

[0004] The bone crusher provided in this application adopts the following technical solution:

[0005] A bone crusher includes a body with a first dust removal zone and a second dust removal zone. A feeding hopper for holding bones is located within the first dust removal zone. A drive unit for rotating the feeding hopper is also located within the body. A crushing assembly for crushing the bones is located within the first dust removal zone. When the drive unit rotates the feeding hopper, the bones fall into the crushing assembly. A receiving hopper is rotatably mounted on the body to receive the crushed bone ash. The receiving hopper is located between the first and second dust removal zones. A worktable is located within the second dust removal zone to facilitate the worker turning the bone ash in the receiving hopper and pouring it into an urn. A first dust removal assembly is located within the first dust removal zone, and a second dust removal assembly is located within the second dust removal zone.

[0006] By adopting the above technical solution, workers pour the cremated bones into the feeding hopper, and then the drive unit drives the feeding hopper to rotate, pouring the bones into the crushing component. After crushing, the ashes fall into the receiving hopper. Then, workers place the urn on the workbench and rotate the receiving hopper to pour the ashes into the urn. Compared with the traditional method of manual crushing, the manual labor intensity is low and the degree of automation is high. In addition, during this process, the first and second dust removal components absorb the dust generated during the turning or pouring, which helps to reduce environmental pollution.

[0007] Preferably, the crushing assembly includes a plurality of crushing rollers rotatably connected to the machine body and a first motor that drives all the crushing rollers to rotate synchronously, and a crushing gap for crushing bones is formed between adjacent crushing rollers.

[0008] By adopting the above technical solution, the first motor rotates, driving all the crushing rollers to rotate. When the bone falls from the feeding hopper into the crushing gap, the crushing rollers crush the bone.

[0009] Preferably, the feeding hopper is rotatably connected to the machine body, and a discharge port is formed on one side of the feeding hopper. The rotation axis of the feeding hopper is parallel to the rotation axis of the crushing roller. The rotation connection point of the feeding hopper is located at the discharge port. The driving component is a first electric cylinder, which is located below the feeding hopper. The piston rod end of the first electric cylinder is hinged to the bottom of the feeding hopper. The hinge point between the first electric cylinder and the feeding hopper is located on the side of the feeding hopper away from the discharge port. The cylinder body of the first electric cylinder is hinged to the machine body. The rotation axes at both ends of the first electric cylinder are parallel to the rotation axis of the crushing roller.

[0010] By adopting the above technical solution, when the worker puts the bone into the feeding hopper, the first electric cylinder operates, causing the piston rod to extend and retract, thereby rotating the feeding hopper and causing the bone to fall from the discharge port into the crushing gap for crushing.

[0011] Preferably, the machine body is provided with a receiving hopper below the crushing gap, the outlet of the receiving hopper is located above the receiving hopper, the machine body is provided with a lifting assembly for driving the receiving hopper to rise and fall, and the machine body is also provided with a sliding component for driving the receiving hopper to slide to avoid the rising and falling of the receiving hopper.

[0012] By adopting the above technical solution, the ashes after being crushed by the crushing roller will enter the receiving hopper and fall from the receiving hopper into the receiving hopper. Then, the sliding component drives the receiving hopper to slide away from the receiving hopper. At this time, the receiving hopper will not block the upward path of the receiving hopper. The lifting component then drives the receiving hopper to rise to the height of the worktable, which facilitates the loading of ashes.

[0013] Preferably, the sliding component is configured as a second electric cylinder, which is located inside the machine body, and the piston rod end of the second electric cylinder is connected to the receiving hopper. A guide rod is mounted on the machine body, and a sleeve block fitted on the guide rod is provided on the side of the receiving hopper.

[0014] By adopting the above technical solution, the second electric cylinder is operated, the piston rod extends and retracts, and the receiving hopper slides along the guide rod, thus realizing the sliding of the receiving hopper. The sliding connection between the guide rod and the sleeve block helps to improve the stability of the receiving hopper's sliding.

[0015] Preferably, the lifting assembly includes a vertically arranged lead screw slide and a second motor that drives the lead screw in the lead screw slide to rotate. A support plate is horizontally arranged on the slide of the lead screw slide. The bottom wall of the receiving hopper overlaps the support plate. The receiving hopper is hinged to the side of the support plate away from the receiving hopper. The rotation axis of the receiving hopper is horizontally arranged.

[0016] By adopting the above technical solution, the second motor drives the lead screw to rotate, which in turn drives the support plate to move up and down on the lead screw along with the slide table, thus realizing the lifting and lowering of the hopper. The hopper is hinged to the side wall of the support plate. When the hopper rises, the staff can directly flip the hopper to pour out the ashes inside.

[0017] Preferably, the first dust removal component is configured as a first dust extraction hood installed in the first dust removal area and an exhaust duct connected to the first dust extraction hood.

[0018] By adopting the above technical solution, when workers pour bones into the hopper, the dust will be stirred up. At this time, the dust will be drawn away by the first dust extraction hood, which helps to prevent environmental pollution. In addition, when the hopper is turned over and the bones are poured into the crushing gap, dust will also be generated. Moreover, when the crushing roller crushes the bones, a lot of dust will also be generated. By using the first dust extraction hood to absorb the dust generated here and discharge it to the subsequent dust treatment device, the environmental pollution in this process can be greatly reduced.

[0019] Preferably, a second dust extraction hood is provided on the side of the machine body away from the receiving hopper, and the second dust extraction hood is vertically arranged.

[0020] By adopting the above technical solution, a large amount of dust is generated when the cremated remains enter the receiving hopper, and dust continues to be generated during the rising process of the receiving hopper. The second dust extraction hood helps to reduce dust discharge and pollution. In addition, the second dust extraction hood is set vertically, which helps to directly extract the dust during the rising process, shortening the time that the dust stays in the air, and thus helping to reduce dust pollution to the environment.

[0021] Preferably, the exhaust port of the second dust extraction hood faces the material receiving hopper, and the exhaust port of the second dust extraction hood is arranged in a trapezoidal shape.

[0022] By adopting the above technical solution, the exhaust port of the second dust hood is set in a trapezoidal shape, which surrounds the material receiving hopper, increases the exhaust area, and helps to improve the dust removal efficiency.

[0023] Preferably, a collection box is provided below the workbench of the machine body, and a dust collection port communicating with the collection box is provided on the workbench.

[0024] By adopting the above technical solution, after the ashes in the hopper are poured into the urn, although the second dust removal component will play a role in dust removal during the process, some dust will still fall on the workbench. At this time, a brush can be used to brush the dust on the workbench into the collection box from the dust outlet, which helps to keep the workbench clean.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The bones are poured into the feeding hopper, and then the first electric cylinder drives the feeding hopper to rotate, pouring the bones into the crushing gap. The crushing roller crushes the bones. Then the receiving hopper receives the ashes and rises above the worktable. After that, the receiving hopper is flipped to pour the ashes into the urn. The whole process is highly automated. Compared with traditional manual operation, the labor intensity of workers is low and the efficiency is higher.

[0027] 2. The use of the first and second dust removal components to remove dust generated throughout the process helps reduce environmental pollution;

[0028] 3. The use of the second dust extraction hood to form a three-stage dust removal system with the first and second dust removal zones helps to greatly reduce dust pollution to the environment. The opening of the second dust extraction hood is trapezoidal and distributed along the vertical direction, which helps to improve the dust extraction efficiency. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] This application discloses a bone crusher.

[0036] Reference Figure 1 and Figure 2 The bone crusher includes a body 1 with an opening on one side. Inside the body 1, there are a first dust removal zone 2, a transfer zone 3, and a second dust removal zone 4. In the first dust removal zone 2, a feeding hopper 4 for placing bones is attached to the body 1. Below the feeding hopper 4, the body 1 is equipped with a drive unit for rotating the feeding hopper 4. The body 1 is also equipped with a crushing component 5 for crushing bones. When the drive unit drives the feeding hopper 4 to rotate, the bones will fall into the crushing component 5 for crushing.

[0037] The machine body 1 is located below the crushing component 5 and is equipped with a receiving hopper 6 for receiving cremated remains; the machine body 1 is located in the transfer zone 3 and is equipped with a lifting hopper 7 for receiving cremated remains in the receiving hopper 6; the machine body 1 is located in the transfer zone 3 and is equipped with a lifting component 8 for driving the lifting of the lifting hopper 7; the machine body 1 is located in the second dust removal zone 4 and is equipped with a workbench 41. When the lifting hopper 7 rises above the workbench 41, the staff pours the cremated remains into the urn in the second dust removal zone 4.

[0038] The machine body 1 is provided with a first dust removal component 9 in the first dust removal zone 2 and a second dust removal component 10 in the second dust removal zone 4.

[0039] Reference Figure 2 and Figure 3The crushing assembly 5 includes two crushing rollers 51 rotatably connected to the body 1 and a first motor 52 that drives the two crushing rollers 51 to rotate synchronously. A crushing gap 53 for crushing bones is formed between the two crushing rollers 51. Gears mesh at the ends of both crushing rollers 51, with two gears at the same end meshing. The output shaft of the first motor 52 rotates coaxially with one of the crushing rollers 51. The first motor 52 drives one of the crushing rollers 51 to rotate. Under the action of the gears, the two crushing rollers 51 rotate synchronously, forming a crushing biting force in the crushing gap 53, thereby crushing the bone that enters the crushing gap 53.

[0040] Reference Figure 1 The machine body 1 is covered with a dust cover 54 above the crushing roller 51. The dust cover 54 is open, with the opening facing the feeding hopper 4. This helps to prevent splashing during the crushing of bones.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A discharge port 41 is formed on the side of the feeding hopper 4 near the crushing roller 51. The discharge port 41 of the feeding hopper 4 is hinged to the machine body 1. The rotation axis of the feeding hopper 4 is parallel to the rotation axis of the crushing roller 51. The driving component is a first electric cylinder 21, which is located below the feeding hopper 4. The piston rod end of the first electric cylinder 21 is hinged to the feeding hopper 4, and the hinge point is located on the side away from the discharge port 41. A mounting block 11 is fixedly installed on the machine body 1 below the feeding hopper 4. The mounting block 11 is made of profile. The cylinder body of the first electric cylinder 21 is hinged to the mounting block 11. The rotation axes at both ends of the first electric cylinder 21 are parallel to the rotation axis of the crushing roller 51. When the first electric cylinder 21 operates, it drives the piston rod to extend, causing the feeding hopper 4 to rotate, thereby causing the bone to slide from the discharge port 41 into the crushing gap 53.

[0042] The machine body 1 has a drawer 12 installed on the side of the feeding hopper 4 away from the crushing roller 51. When the worker pours the bones into the feeding hopper 4, there will be a lot of impurities because the bones have just been cremated. At this time, the worker can pick out the impurities and temporarily put them into the drawer 12.

[0043] Reference Figure 2 and Figure 3The receiving hopper 6 is located below the crushing gap and is slidably connected to the machine body 1. The receiving hopper 6 is inclined along the direction of the crushing roller 51 near the receiving hopper 7. The machine body 1 is provided with a sliding component below the upper hopper 4. The sliding component is a second electric cylinder 22. The cylinder body of the second electric cylinder 22 is hinged to the mounting block 11, and the piston rod of the second electric cylinder 22 is hinged to the receiving hopper 6. Guide rods 13 are mounted on both sides of the machine body 1 on the receiving hopper 6. The receiving hopper 6 and the corresponding guide rod 13 are fixedly connected with a sleeve block 61. The sleeve block 61 and the corresponding guide rod 13 are inserted and slidably engaged. The guide rod 13 is horizontally set and its length direction is perpendicular to the rotation axis of the crushing roller 51.

[0044] The opening of the receiving hopper 6 is located above the receiving hopper 7. Therefore, when the receiving hopper 7 needs to rise, the second electric cylinder 22 operates, the piston rod retracts, and the receiving hopper 6 slides on the guide rod 13, thereby avoiding the lifting and lowering movement of the receiving hopper 7.

[0045] Reference Figure 2 and Figure 4 The lifting assembly 8 includes a vertically arranged lead screw slide 81 and a second motor 82 that drives the lead screw in the lead screw slide 81 to rotate. The second motor 82 is fixedly installed in the transfer area 3 of the machine body 1 and located on the upper side of the machine body 1. The output shaft of the second motor 82 is vertically downward and is coaxially fixedly connected to the lead screw. A support plate 811 is fixedly installed on the slide of the lead screw slide 81. The support plate 811 is horizontally arranged, and the bottom wall of the receiving hopper 7 overlaps on the support plate 811. The receiving hopper 7 is hinged to the side of the support plate 811 away from the receiving hopper 6. The rotation axis of the receiving hopper 7 is parallel to the rotation axis of the crushing roller 51. When the second motor 82 operates, it drives the lead screw to rotate, realizing the lifting and lowering movement of the support plate 811, that is, realizing the lifting and lowering movement of the receiving hopper 7.

[0046] A cover plate 20 is fixedly installed on the body 1 around the lead screw slide 81 and the second motor 82 to facilitate the movement of both, which helps to make the bone crusher look more aesthetically pleasing. In addition, a clearance groove 201 is provided on the cover plate 20 to allow the support plate 811 to rise and fall.

[0047] When the support plate 811 raises the hopper 7 above the workbench 41, the staff first places the urn on the workbench 41, then inserts a funnel into the opening of the urn, and then flips the hopper 7 so that the ashes enter the urn from the funnel.

[0048] Reference Figure 1 and Figure 3The first dust removal assembly 9 includes a first dust extraction hood 91 installed in the first dust removal zone 2 and an exhaust duct 92 connected to the first dust extraction hood 91. The structure of the second dust removal assembly 10 is the same as that of the first dust removal assembly 9, and will not be described again. The two exhaust ducts 92 are interconnected and connected to an external dust treatment device. The first dust extraction hood 91 has several exhaust holes. By using a fan to apply suction force to the exhaust duct 92, the dust in the first dust removal zone 2 and the second dust removal zone 4 is drawn away from the two first dust extraction hoods 91, thus achieving the dust removal operation.

[0049] Reference Figure 2 and Figure 4 The machine body 1 is fixedly installed in the transfer area 3 with a second dust extraction hood 30. The second dust extraction hood 30 is vertically arranged and located on the side of the material receiving hopper 7 away from the material receiving hopper 6. The second dust extraction hood 30 is trapezoidal in shape and has several exhaust ports. The second dust extraction hood 30 is connected to the exhaust pipe 92.

[0050] When cremated remains are poured from receiving hopper 6 into receiving hopper 7, dust will be generated. The dust can be removed using the second dust extraction hood 30, reducing environmental pollution. In addition, the second dust extraction hood 30 is set vertically, which increases the ventilation area and helps to continuously remove dust during the rising process of receiving hopper 7, thus further improving dust removal efficiency.

[0051] Reference Figure 2 The machine body 1 is located below the workbench 41 and a collection box 14 is installed. The workbench 41 has a dust discharge port 42 corresponding to the collection box 14. The dust discharge port 42 is connected to the collection box 14. When the surface of the workbench 41 in the second dust removal area 4 is covered with dust, the staff can use a brush to brush the dust from the dust discharge port 42 into the collection box 14, which helps to keep the surface of the workbench 41 clean.

[0052] The implementation principle of the bone crusher in this embodiment is as follows: the crushing roller 51 is used to crush the bones, eliminating the need for manual hammering and greatly reducing the labor intensity. In addition, the rotation of the upper hopper 4 and the lifting of the receiving hopper 7 help to improve the automation level of the crusher. Furthermore, the three-stage dust removal method helps to greatly reduce the dust overflowing during the process, thus helping to reduce environmental pollution. The second dust extraction hood 30 is vertically arranged, which helps to remove dust in the receiving hopper 7. On the other hand, when the receiving hopper 6 slides away from the receiving hopper 7, dust may overflow from the outlet of the receiving hopper 6. At this time, the second dust extraction hood 30 can remove this dust, thereby helping to reduce the accumulation of dust in the machine body 1 and reduce environmental pollution.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
