[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides a technical solution: a livestock product grinding device, including a handle 1, a grinding component at the front end of the handle 1, a first mounting cylinder 2 connected to the front end of the handle 1, a second mounting cylinder 3 extending radially along the outer wall of the first mounting cylinder 2, a rotating cylinder 12 rotatably mounted inside the second mounting cylinder 3, a grinding disc 4 mounted at the bottom center of the rotating cylinder 12, a drive motor 9 mounted inside the first mounting cylinder 2, a drive bevel gear 10 connected to the drive end of the drive motor 9, and a grinding disc 4 on the outer wall of the rotating cylinder 12. The first driven bevel gear 11 meshes with the driving bevel gear 10. A rotating shaft 16 is also rotatably mounted inside the first mounting cylinder 2. The bottom end of the rotating shaft 16 extends into the interior of the rotating cylinder 12 and is connected to a fan blade 20. A second driven bevel gear 17 that meshes with the driving bevel gear 10 is mounted on the outer wall of the rotating shaft 16. An outer hole 8 is opened on the wall of the second mounting cylinder 3. A negative pressure hole 19 communicating with the outer hole 8 is opened on the side wall of the rotating cylinder 12. A filter screen 15 is installed at the port at the top of the rotating cylinder 12. A vent hole 6 communicating with the interior of the first mounting cylinder 2 is opened on the outer wall of the first mounting cylinder 2.
[0024] Specifically, the handle 1 is convenient for the operator to hold, and the drive motor 9 is located inside the first mounting cylinder 2. After starting, the drive end drives the active bevel gear 10 to rotate. The active bevel gear 10 meshes with the first driven bevel gear 11, thereby driving the rotating cylinder 12 to rotate inside the second mounting cylinder 3. The grinding disc 4 at the bottom of the rotating cylinder 12 rotates accordingly to perform grinding operations. At the same time, the active bevel gear 10 meshes with the second driven bevel gear 17, driving the rotating shaft 16 to rotate. The fan blades 20 at the bottom of the rotating shaft 16 rotate inside the rotating cylinder 12. The rotation of the fan blades 20 causes air to flow inside the rotating cylinder 12, forming a negative pressure. The outer hole 8 on the wall of the second mounting cylinder 3 is connected to the negative pressure hole 19 on the side wall of the rotating cylinder 12. Dust-laden air from the outside enters the rotating cylinder 12 through the outer hole 8 and the negative pressure hole 19. After being filtered by the filter screen 15, the clean air is discharged from the vent hole 6, thus completing the dust collection. This structural design integrates grinding and dust collection functions, solving the problem of poor dust collection effect in traditional grinding devices. The grinding disc 4 is rotated by the drive motor 9, which improves grinding efficiency and reduces manual labor intensity. The active bevel gear 10 simultaneously drives the grinding disc 4 to rotate and generates negative pressure dust collection with the fan blade 20. The structure is compact and has a high space utilization rate.
[0025] See Figure 4 The bottom surface of the rotating cylinder 12 is provided with a mounting post 13 extending along its axial direction. The grinding disc 4 is mounted on the mounting post 13, and the grinding surface of the grinding disc 4 is exposed to the outside of the second mounting cylinder 3.
[0026] Specifically, the mounting post 13 on the bottom surface of the rotating cylinder 12 is used to install the grinding disc 4, ensuring that the grinding disc 4 is firmly connected to the rotating cylinder 12 and rotates together with the rotating cylinder 12. The grinding surface is exposed outside the second mounting cylinder 3 and directly contacts the livestock products for grinding. The setting of the mounting post 13 facilitates the installation and replacement of the grinding disc 4, improves the convenience of device maintenance, and the exposed grinding surface design makes the grinding operation direct and efficient, and can accurately act on the livestock products.
[0027] See Figure 4 A dust discharge channel is provided on the side wall of the second mounting cylinder 3, and a dust discharge port 18 is provided on the side wall of the rotating cylinder 12. The dust discharge channel and the dust discharge port 18 are on the same horizontal line. When the rotating cylinder 12 rotates to the designated position, the dust discharge port 18 is connected to the dust discharge channel. A sealing bolt 5 is provided inside the dust discharge channel.
[0028] Specifically, during the rotation of the rotating cylinder 12, when the dust discharge port 18 and the dust discharge channel on the side wall of the second mounting cylinder 3 are on the same horizontal line, the two are connected. At this time, the sealing bolt 5 can be opened, and the dust collected in the rotating cylinder 12 is discharged through the dust discharge channel. The design of the dust discharge channel and the dust discharge port 18 facilitates centralized cleaning of the dust in the rotating cylinder 12, avoids dust accumulation affecting the dust collection effect and device operation, and improves the continuous working capability of the device.
[0029] See Figure 4The dust discharge channel has internal threads, and the sealing bolt 5 has external threads that are compatible with the internal threads on its outer wall.
[0030] Specifically, the internal thread inside the dust discharge channel matches the external thread on the outer wall of the sealing bolt 5. Tightening the sealing bolt 5 can seal the dust discharge channel and prevent dust leakage during the dust collection process. The threaded connection method has a good sealing effect, is easy to operate, and facilitates the opening and closing of the dust discharge channel, ensuring the normal operation of the dust collection system.
[0031] See Figure 2 and Figure 4 A through-hole 14 is provided on the bottom wall of the rotating cylinder 12, and an inner hole 7 is provided in the middle of the grinding disc 4, with the inner hole 7 corresponding to the through-hole 14.
[0032] Specifically, the dust generated during the grinding process can enter the interior of the rotating cylinder 12 through the inner hole 7 and the through-hole 14 for easy collection; the setting of the inner hole 7 and the through-hole 14 increases the channels for dust to enter the rotating cylinder 12, improves the dust collection efficiency, and enables the dust in the grinding area to be collected more quickly.
[0033] See Figure 2 and Figure 4 Multiple outer holes 8 are provided, and the multiple outer holes 8 are arranged equidistantly along the lower end face of the second mounting cylinder 3, with the bottom end of the outer hole 8 facing the outer peripheral wall of the grinding disc 4.
[0034] Specifically, when the grinding disc 4 rotates, the dust generated around it can enter the rotating cylinder 12 from multiple directions through the outer holes 8; the multiple outer holes 8 arranged circumferentially at equal intervals expand the dust collection range, which can more comprehensively collect the dust generated during the grinding process and further improve the dust collection effect.
[0035] See Figure 4 The filter screen 15 has a perforation in the middle, and the bottom end of the rotating shaft 16 extends through the perforation into the interior of the rotating cylinder 12.
[0036] Specifically, the perforated design ensures that the rotation of the shaft 16 is not affected, and the filter 15 effectively filters dust in the air, preventing the exhaust air from polluting the environment again and protecting the health of operators.
[0037] See Figure 1 The handle 1 is a cylindrical structure, and the outer wall of the handle 1 has an integrally formed anti-slip texture.
[0038] Specifically, the cylindrical structure and anti-slip texture design improve the comfort and safety of operators when using the grinding device, facilitate stable operation, and improve the quality of grinding operations.
[0039] Working principle:
[0040] The operator holds the handle 1 and starts the drive motor 9 located in the first mounting cylinder 2. The drive end of the drive motor 9 drives the active bevel gear 10 to rotate at high speed. The active bevel gear 10 meshes with the first driven bevel gear 11, driving the rotating cylinder 12 to rotate stably in the second mounting cylinder 3. The grinding disc 4 installed at the bottom of the rotating cylinder 12 rotates at high speed to grind the livestock products. The grinding disc 4 is firmly connected to the bottom surface of the rotating cylinder 12 through the mounting column 13 to ensure stable rotation.
[0041] While driving the rotating cylinder 12 to rotate, the active bevel gear 10 meshes with the second driven bevel gear 17, driving the rotating shaft 16 to rotate. The fan blade 20, installed at the bottom of the rotating shaft 16, rotates at high speed inside the rotating cylinder 12. The rotation of the fan blade 20 causes the air inside the rotating cylinder 12 to flow rapidly, forming a negative pressure environment. The outer hole 8 on the wall of the second mounting cylinder 3 is connected to the negative pressure hole 19 on the side wall of the rotating cylinder 12. Under the action of negative pressure, the dust-laden air generated during the grinding process enters through the outer hole 8 and passes through the negative pressure hole 19 into the interior of the rotating cylinder 12. Multiple outer holes 8 are equidistantly arranged circumferentially along the lower end face of the second mounting cylinder 3, with their ports facing the outer peripheral wall of the grinding disc 4, ensuring that dust generated in all directions around the grinding disc 4 can be effectively sucked in when the grinding disc 4 rotates. The inner hole 7 in the middle of the grinding disc 4 corresponds to the opening 14 on the bottom wall of the rotating cylinder 12, increasing the channel for dust to enter the rotating cylinder 12. The dust-laden air passes through the filter screen 15 inside the rotating cylinder 12. The dust is filtered and intercepted, while clean air is discharged through the vent 6 on the outer wall of the first mounting cylinder 2. When a large amount of dust is collected in the rotating cylinder 12, the rotating cylinder 12 is rotated so that the dust discharge port 18 is on the same horizontal line as the dust discharge channel on the side wall of the second mounting cylinder 3. The sealing bolt 5 is then opened to discharge the dust. The negative pressure generated by the rotation of the fan blade 20 is used for dust collection. The design of multiple outer holes 8, inner holes 7 and through-holes 14 greatly expands the dust collection range and increases the dust entry channels, effectively solving the problem of poor dust collection effect of traditional grinding devices. This greatly reduces the pollution of the working environment by dust. The filter screen 15 filters the discharged air to prevent the discharged air from polluting the environment again, protects the health of the operators, and meets environmental protection requirements. The design of the dust discharge channel and the dust discharge port 18 makes it easy to clean the dust in the rotating cylinder 12, reduces the maintenance difficulty of the dust collection system, and improves the continuous effectiveness of the dust collection function.
[0042] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
