Description

Technical Field

[0001] The invention relates to a bone and meat crushing technology, in particular to a meat mincer and bone paste grinding integrated machine. Background Art

[0002] Farms for dogs, fish, turtles, crabs, crayfish, etc. need to grind bones and meat before feeding. The crushed bones and meat are easier for these animals to digest and absorb. For dogs, the crushed bones and meat can provide a better taste, easy to chew and swallow, and also help the comprehensive absorption of nutrients. For aquatic animals such as fish, turtles, crabs and crayfish, the crushed bones and meat can form finer particles, which are convenient for them to eat and digest in water. In addition, the crushing process can also increase the surface area of ​​the feed, making it easier for water and nutrients to contact and dissolve, thereby improving the digestibility of the feed. At the same time, the crushed feed can also reduce water pollution and improve breeding efficiency. Therefore, bone and meat grinding is an important means for farms to improve animal feeding efficiency and health levels.

[0086] The specific implementation is as follows: the power source 8 is located below the auger unit 3, the power source 8 includes but is not limited to a drive motor, the power source 8 is electrically connected to an external power source, and is also controlled by an external PLC programming program.

[0087] Embodiment three:

[0088] The power transmission component can also include a stepper motor, which is fixedly mounted on the top of the bottom support rod 7 through a mounting bracket. The output shaft axis of the stepper motor is parallel to the axis of the cutter housing 31. The output end of the stepper motor is fixedly mounted with a driving gear through a coupling.

The stepper motor drives the driven gear through the driving gear to drive the power transmission shaft 33 to rotate.

[0089] Working principle: When in use, the user puts the material to be processed (such as meat, bones, etc.) into the unloading frame 1.

[0090] Under the action of gravity, the material enters the cutter unit 3 through the connecting portion between the material discharge frame 1 and the cutter housing 31 .

[0091] The auger shaft 34 starts to rotate under the drive of the power transmission assembly, and the auger blades 35 rotate accordingly and push the material to move along the inner wall of the cutter housing 31 .

[0092] The rotation of the auger blades 35 not only achieves the initial crushing of the material, but also pushes it to the subsequent grinding components.

[0093] When the material is pushed between the fixed knife 36 and the movable knife 37 by the auger blade 35, the movable knife 37 rotates under the drive of the auger shaft 34, and forms a shearing effect with the fixed knife 36 to further cut and crush the material.

[0094] The small blade or round hole design of the fixed knife 36 helps to cut the material better, while the rotating blade of the movable knife 37 further refines the material through the rotating cutting action.

[0095] After being processed by the fixed knife 36 and the movable knife 37, the particle size of the material is significantly reduced.

[0096] The cut material is continuously pushed by the auger blade 35 and passes through the orifice plate 38. The through holes on the orifice plate 38 play a screening role, blocking impurities such as bone residues, fascia and blood vessels in the meat, while limiting the particle size of the material.

[0097] Materials with larger particle sizes are blocked by the orifice plate 38 and continue to be cut by the movable knife 37 and the fixed knife 36 until the screening requirements of the orifice plate 38 are met.

[0098] The material screened by the perforated plate 38 enters the space between the grinding disc 1 39 and the grinding disc 2 310 .

[0099] Grinding disc 1 39 and grinding disc 2 310 are respectively provided with a conical driving groove and a conical driven groove. When grinding disc 1 39 rotates, grinding disc 2 310 is driven to rotate through the interaction of the conical grooves.

[0100] The close contact and relative rotation between the two grinding discs give the material a final grinding until it reaches a slurry state.

[0101] The ground material flows out through the gap between the grinding disc mounting disc 311 and the pressing disc 314, completing the entire processing process.

[0102] The compression spring 312 makes the grinding disc 2 310 close to the grinding disc 1 39 without the influence of external force, ensuring the close contact between the two grinding discs.

[0103] When the material fills the grinding disc space, the grinding disc 2 310 is squeezed by the material to overcome the elastic force of the compression spring 312 and separate from the grinding disc 1 39, providing space for the material to flow out.

[0104] The clamping nut 313 is used to adjust the preload force of the clamping spring 312, thereby adjusting the gap between the grinding disc 1 39 and the grinding disc 2 310 to meet the grinding requirements of different materials.

[0105] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
