Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet food production and processing technology, and in particular to a bone crushing and grinding device for pet food production and processing. Background Technology
[0002] Pet food is food specifically designed for pets, falling between human food and traditional livestock feed. Its main function is to provide various pets with the most basic nutrients needed for life, growth, development, and health. It has advantages such as comprehensive nutrition, high digestibility and absorption rate, scientific formula, convenient feeding, and prevention of certain diseases. Some discarded livestock bones on the market are also one of the raw materials for pet food processing. The bone pieces are of different sizes and need to be crushed by a crusher. After the bones are crushed, they are ground. Currently, bone crushing equipment and bone grinding equipment are separate and different devices. The crushed bones are added to the grinder for grinding, and incomplete bone crushing increases the grinding time of the grinding equipment. Insufficient bone crushing reduces the efficiency of bone production and processing.
[0003] Existing patent CN216678536U discloses a bone crushing and grinding device for pet food production and processing, including a feeding chamber, a rotating roller, a crushing chamber, a conveying pipe, a hydraulic rod, a grinding chamber, a first motor, and a second motor.

The rotating roller is located inside the feeding chamber, and a third motor is located on one side of the feeding chamber. A rotating wheel is located at one end of the rotating roller. The first motor and the second motor are located on one side of the grinding chamber and the crushing chamber. A discharge pipe and a conveying pipe are located at the lower end of the grinding chamber and the crushing chamber. A hydraulic rod is located on one side of the inner wall of the grinding chamber. A pressing plate and a rotating plate are located at the end of the hydraulic rod opposite to the first motor. This prior art uses the rotating roller to initially crush the bones, and the blades further crush the bones. The crushed bones directly enter the grinding chamber, where the pressing plate and the rotating plate grind them, resulting in better crushing and grinding effects and improving the efficiency of bone production and processing.
[0004] However, in the aforementioned prior art, since the interception valve is installed in the middle of the conveying pipe, there will be space for material to accumulate at the connection between the conveying pipe and the crushing chamber, which will result in the material in the space not being fully crushed. Utility Model Content
[0005] The purpose of this utility model is to provide a bone crushing and grinding device for pet food production and processing, which aims to solve the technical problem in the prior art that, because the interception valve is installed in the middle of the conveying pipe, there will be space for material to accumulate at the connection between the conveying pipe and the crushing chamber, which in turn will prevent the material in the space from being fully crushed.
[0006] To achieve the above objectives, this utility model employs a bone crushing and grinding device for pet food production and processing, comprising a crushing chamber, a conical hopper, a grinding chamber, and a material control mechanism. A feeding chamber is located above the crushing chamber, and crushing blades are installed inside the crushing chamber, driven by a first motor. A connecting pipe is located below the conical hopper.

A second motor is installed at the other end of the grinding chamber, and a fixed grinding plate is installed at the output end of the second motor. A discharge hopper is located below the grinding chamber. The crushing chamber is connected to the conical hopper. Located on the conical hopper, the connecting pipe communicates with the grinding chamber and is located above the grinding chamber. The material control mechanism includes two material control plates and multiple electric telescopic rods. Both sides of the grinding chamber have through holes. The two material control plates are slidably connected to the grinding chamber and are located in the corresponding through holes. The two material control plates extend in opposite directions to directly below the grinding blades. The two material control plates are also fixedly connected to the corresponding two electric telescopic rods and are located at the output end of the electric telescopic rods. The multiple electric telescopic rods are fixedly connected to the grinding chamber and are symmetrically arranged in pairs on the front and rear end faces of the grinding chamber.
[0007] One of the material control plates has multiple triangular grooves at one end, and the triangular grooves extend through the other end of the material control plate. The other material control plate has multiple triangular rods at one end, and the triangular rods are located within the triangular grooves.
[0008] One of the material control plates has an installation box at one end, and a collection box is slidably disposed inside the installation box, with the collection box located below the plurality of triangular grooves.
[0009] The bone crushing and grinding device for pet food production and processing further includes a crushing mechanism, which includes a first crushing roller and a second crushing roller.

[0011] This utility model discloses a bone crushing and grinding device for pet food production and processing, comprising a crushing chamber, a conical hopper, a grinding chamber, and a material control mechanism. A feeding chamber is located above the crushing chamber, and crushing blades are installed inside the crushing chamber, driven by a first motor. A connecting pipe is located below the conical hopper. A hydraulic cylinder is installed at one end of the grinding chamber, and a pressing grinding plate is installed at the output end of the hydraulic cylinder. A second motor is installed at the other end of the grinding chamber, and a fixed grinding plate is installed at the output end of the second motor. A discharge hopper is located below the grinding chamber. By setting two material control plates to directly support the material, the material is prevented from directly entering the conveying pipe. After eliminating the material accumulation space, all materials can smoothly pass through the telescopic crushing chamber and be fully crushed, thereby improving the overall crushing efficiency. This method solves the technical problem that because the interception valve is installed in the middle of the conveying pipe, there is space for material accumulation at the connection between the conveying pipe and the crushing chamber, which prevents the material in this space from being fully crushed.

Detailed Implementation
[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] Please see Figures 1-5 This utility model provides a bone crushing and grinding device for pet food production and processing, including a crushing chamber 1, a conical hopper 2, and a grinding chamber 3. A feeding chamber 4 is located above the crushing chamber 1. Crushing blades 5 are installed inside the crushing chamber 1 and are driven by a first motor 6. A connecting pipe 7 is located below the conical hopper 2. A hydraulic cylinder 8 is installed at one end of the grinding chamber 3, and a pressing grinding plate 9 is installed at the output end of the hydraulic cylinder 8. A second motor 10 is installed at the other end of the grinding chamber 3, and a fixed grinding plate 11 is installed at the output end of the second motor 10. A discharge hopper 12 is located below the grinding chamber 3. The crushing chamber 1 communicates with and is located on the conical hopper 2. The connecting pipe 7 communicates with and is located above the grinding chamber 3. Bone is poured into the feeding chamber... The bone enters the crushing chamber 1 through the feeding chamber 4. The first motor 6 is started, which drives the crushing blades 5 to crush the material. The crushed material stays on the material control mechanism, allowing the crushing blades 5 to crush the material. Then, by controlling the material control mechanism, the material enters the connecting pipe 7 from the conical hopper 2, and then enters the grinding chamber 3. The hydraulic cylinder 8 is then started, which pushes the extrusion grinding plate 9 towards the fixed grinding plate 11, pushing the material. When the extrusion grinding plate 9 and the fixed grinding plate 11 are a certain distance apart, the second motor 10 is started, which rotates the fixed grinding plate 11 to grind the material. The ground material is discharged through the discharge hopper 12.
[0021] In this specific embodiment, the material control mechanism includes two material control plates 13 and multiple electric telescopic rods 14. Both sides of the crushing chamber 1 have through holes 15. The two material control plates 13 are slidably connected to the crushing chamber 1 and located within the corresponding through holes 15. The two material control plates 13 extend in opposite directions directly below the crushing blade 5. The two material control plates 13 are also fixedly connected to the corresponding two electric telescopic rods 14 and located at the output end of the electric telescopic rods 14. The multiple electric telescopic rods 14 are fixedly connected to the crushing chamber 1 and symmetrically arranged in pairs on the front and rear end faces of the crushing chamber 1. By setting the two material control plates 13 to directly support the material, the material is prevented from directly entering the conveying pipe. After eliminating the material accumulation space, all materials can smoothly pass through the telescopic crushing chamber 1 and be fully crushed, thereby improving the overall crushing efficiency. This method solves the technical problem that because the interception valve is installed in the middle of the conveying pipe, there is space for material accumulation at the connection between the conveying pipe and the crushing chamber 1, resulting in the material in this space not being fully crushed.
[0022] One of the material control plates 13 has multiple triangular grooves 16 at one end, and the triangular grooves 16 extend through the other end of the material control plate 13. The other material control plate 13 has multiple triangular rods 17 at one end, and the triangular rods 17 are located within the triangular grooves 16. This design allows the two material control plates 13 to fit more tightly when closed, preventing material from leaking out of the gaps. At the same time, the structure of the triangular grooves 16 and the triangular rods 17 also helps the material to fall more smoothly when the material control plates 13 are opened.
[0023] Secondly, one of the material control plates 13 is provided with an installation box 18 at the other end. A collection box 19 is slidably disposed inside the installation box 18, and the collection box 19 is located below the plurality of triangular grooves 16. The design of the installation box 18 and the collection box 19 can collect small materials falling from the triangular grooves 16, avoiding the accumulation or blockage of these materials in the triangular grooves 16.
[0024] Furthermore, the bone crushing and grinding device for pet food production and processing also includes a crushing mechanism, which includes a first crushing roller 20 and a second crushing roller 21. One end of the first crushing roller 20 is provided with a driven gear 22, and one end of the second crushing roller 21 is provided with a driving gear 23. The second crushing roller 21 is driven by a third motor 24. Both the first crushing roller 20 and the second crushing roller 21 are rotatably disposed in the feeding chamber 4, and the driving gear 23 meshes with the driven gear 22. The material is initially crushed by the first crushing roller 20 and the second crushing roller 21, making it easier for the subsequent crushing blades 5 to crush. This not only improves the crushing efficiency but also reduces the wear and energy consumption of the crushing blades 5. In addition, the third motor 24 drives the second crushing roller 21 clockwise, and the first crushing roller 20 rotates counterclockwise under the action of the driving gear 23 and the driven gear 22, thereby forming a compressive force for crushing the bone.
[0025] In addition, a screen 25 is provided on the discharge hopper 12, and the extrusion grinding plate 9 and the fixed grinding plate 11 both extend between the grinding chamber 3 and the screen 25, and are also located directly below the connecting pipe 7. The screen 25 can easily block large particles of unqualified grinding materials, so that they can be ground again, while qualified grinding materials can be easily discharged through the screen 25.
[0026] When using this invention to control the material control mechanism, by activating multiple electric telescopic rods 14, the material control plate 13 is pushed away from the crushing chamber 1. The material control plate 13 then slowly moves through the through hole 15. At this time, part of the material on the material control plate 13 will fall directly into the conical hopper 2, and the other part will fall into the conical hopper 2 under the obstruction of the inner wall of the crushing chamber 1. When the material control plate 13 moves to the same horizontal line as the inner wall of the crushing chamber, all the material can be discharged into the conical hopper 2. Then, the two material control plates 13 are merged by the electric telescopic rods 14. This method solves the technical problem that because the interception valve is installed in the middle of the conveying pipe, there will be space for material to accumulate at the connection between the conveying pipe and the crushing chamber 1, which will prevent the material in the space from being fully crushed.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
