Description

Technical Field

[0001] The present application relates to the field of feed processing technology, and in particular to an extruder for feed production. Background Art

[0002] Feed extrusion molding device is a device used to process feed raw materials into specific shapes. It is mainly composed of a feeding system, a pressing system, an extrusion system, a cutting system and a temperature control system.

It has the advantages of high production efficiency, low cost and simple operation. It is widely used in poultry and livestock breeding and aquaculture.

[0003] Publication number: CN220799966U, discloses a high-efficiency feed extrusion molding device, which can remove feeds of different sizes and reduce dust in the feed. It does not require secondary screening before packaging, thereby improving feed production efficiency, ensuring feed uniformity and quality, and improving animal feeding efficiency. The combination of the outer shell and the drying fan can achieve a drying effect on the feed, which not only accelerates feed molding, but also improves feed quality, extends storage time, and improves digestibility and safety.

Therefore, when the unformed feed needs to be extruded for a second time, it needs to be transported, replenished with water, and injected into the extruder again to complete its molding, which is relatively inconvenient and reduces the molding efficiency of the feed. Therefore, an extruder for feed production is proposed. Utility Model Content

[0035] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0036] The embodiments of the present application disclose an extruder for feed production.

[0037] Reference Figure 1-Figure 5A feed production extruder includes a shell 1, an extrusion device body 3 for extruding feed is provided on the top of the shell 1, a feed hopper 2 for injecting feed into the extrusion device body 3 is provided on the top of the extrusion device body 3, and the feed hopper 2 is conical for gathering the input feed. One side of the shell 1 is fixedly connected to a fixed cylinder 4 for conveying the screened feed, and the bottom of the fixed cylinder 4 is fixedly connected to a conveying motor 8 for providing power for feed conveying, and the output end of the conveying motor 8 is rotatably connected to the inside of the fixed cylinder 4. The output end of the conveying motor 8 is located on the surface inside the fixed cylinder 4 and is fixedly connected to an auger 13 for conveying the feed. The top of the auger 13 is fixedly connected to a limiting plate 12 for limiting the rotation of the auger 13, and the surface of the limiting plate 12 is rotatably connected to the inner wall of the fixed cylinder 4.

[0038] The surface of the upper end of the fixed cylinder 4 is fixedly connected with a discharge pipe 6 connected to the interior of the fixed cylinder 4. The discharge pipe 6 is located directly above the feed hopper 2, so that the feed transported by the fixed cylinder 4 can fall smoothly into the feed hopper 2 and be extruded again.

[0039] The bottom of the fixed cylinder 4 is fixedly connected to an injection pipe 7 for transporting feed into the fixed cylinder 4. The injection pipe 7 is connected to the interior of the fixed cylinder 4. The end of the injection pipe 7 away from the fixed cylinder 4 is fixedly connected to the shell 1 and is interconnected with the interior of the shell 1, so that the feed in the shell 1 can be introduced into the fixed cylinder 4, realizing the circulation of the feed.

[0040] The inner wall of the shell 1 is slidably connected to a sieve plate 18 for screening the extruded feed, and the inner wall of the shell 1 is slidably connected to a second guide plate 24 for guiding the unformed feed. The second guide plate 24 and the sieve plate 18 are both inclined, and the second guide plate 24 is located at the bottom of the sieve plate 18. The inner wall of the shell 1 is slidably connected to a connecting plate 25 that connects the sieve plate 18 and the second guide plate 24 together. One side of the sieve plate 18 and the second guide plate 24 are fixedly connected to the surface of the connecting plate 25, so that the sieve plate 18 and the second guide plate 24 can move synchronously.

[0041] The bottom of the connecting plate 25 is fixedly connected to a third spring 29 for resetting the connecting plate 25. The end of the third spring 29 away from the connecting plate 25 is fixedly connected to the inner wall of the shell 1. The inner wall of the shell 1 is fixedly connected to a collecting box 20 for collecting unformed feed. The inner wall of the collecting box 20 is arranged at an angle, and the lowest end of the inner wall of the collecting box 20 corresponds to the end of the injection tube 7 located inside the shell 1, so that the feed in the collecting box 20 can smoothly pass through the injection tube 7 into the fixed cylinder 4.

[0042] A first guide plate 19 for guiding the unformed feed is fixedly connected to the inner wall of the shell 1. The first guide plate 19 is arranged at an angle and is also located at the bottom of the screen plate 18. The surface of the first guide plate 19 is fixedly connected to the collection box 20, so that the first guide plate 19 can be used in conjunction with the second guide plate 24 to guide the screened feed and direct the feed into the collection box 20.

[0043] The inner wall of the shell 1 is fixedly connected to a drive motor 21 that provides power for the vibration of the screen plate 18 and the second guide plate 24. The output end of the drive motor 21 is fixedly connected to an elliptical rotating disk 22. The bottom of the second guide plate 24 is fixedly connected to a force-bearing rod 23, and the surface of the force-bearing rod 23 is in contact with the surface of the rotating disk 22.

[0044] The top of the fixed cylinder 4 is fixedly connected with a water storage cylinder 5 for storing water, and the top of the fixed cylinder 4 is fixedly connected with a connecting pipe 14 for transporting water. The connecting pipe 14 connects the water storage cylinder 5 with the interior of the fixed cylinder 4, and the surface of the connecting pipe 14 is fixedly connected with a drainage pipe 15 for water circulation. The drainage pipe 15 and the connecting pipe 14 are connected to each other, and the end of the drainage pipe 15 away from the connecting pipe 14 is fixedly connected with a nozzle 16 for spraying water. The inner wall of the drainage pipe 15 is slidably connected with an extrusion rod 17 for controlling the internal pressure of the connecting pipe 14, and the bottom of the extrusion rod 17 is fixedly connected with an auxiliary extrusion rod 17 for lifting and lowering the moving rod 10. The surface of the moving rod 10 is slidably connected to the inner wall of the fixed cylinder 4, and the surface of the moving rod 10 is fixedly connected with a first spring 9 for resetting the moving rod 10. The end of the first spring 9 away from the moving rod 10 is fixedly connected to the inner wall of the fixed cylinder 4, and the side of the limiting plate 12 away from the auger 13 is fixedly connected with an extrusion block 11 for lifting the moving rod 10, and both sides of the extrusion block 11 are inclined surfaces.

[0045] The inner wall of the connecting pipe 14 is fixedly connected to a fixing ring 26 that provides a flow space for water. The inner wall of the fixing ring 26 is slidably connected to a blocking block 27 that blocks the fixing ring 26 and prevents the flow of water. The cross-section of the blocking block 27 is T-shaped, and the surface of the blocking block 27 is fixedly connected to a second spring 28 for resetting the blocking block 27. The end of the second spring 28 away from the blocking block 27 is fixedly connected to the surface of the fixing ring 26. The inner wall of the drain pipe 15 is also provided with a fixing ring 26, a blocking block 27 and a second spring 28, and is arranged opposite to the fixing ring 26, the blocking block 27 and the second spring 28 in the connecting pipe 14, thereby controlling the flow direction of water in the connecting pipe 14.

[0046] The implementation principle of the feed production extruder of the embodiment of the present application is as follows: after the feed is extruded through the extrusion device body 3, it falls on the surface of the screen plate 18, and at the same time, the drive motor 21 is started, driving the rotating disk 22 to rotate, so that the elliptical rotating disk 22 continuously pushes the force-bearing rod 23, so that the force-bearing rod 23, the second guide plate 24, the connecting plate 25 and the screen plate 18 rise in the shell 1, and the third spring 29 is stretched. After the rotating disk 22 no longer pushes the force-bearing rod 23, under the elastic force of the third spring 29, the force-bearing rod 23, the second guide plate 24, the connecting plate 25 and the screen plate 18 return to their original state, so that as the drive motor 21 is started, the force-bearing rod 23, the second guide plate 24, the connecting plate 25 and the screen plate are driven. 18 is continuously vibrated in the shell 1, thereby vibrating the feed formed on the sieve plate 18, so that the unformed feed passes through the filter holes of the sieve plate 18 and falls on the surface of the second guide plate 24. As the sieve plate 18 and the second guide plate 24 vibrate, the formed feed is discharged along the inclined surface of the sieve plate 18, while the unformed feed enters the collection box 20 along the inclined surface of the second guide plate 24. Similarly, part of the feed that falls on the first guide plate 19 also enters the collection box 20 through the inclined surface of the first guide plate 19, thereby completing the screening of the feed, screening feeds of different sizes, reducing dust in the feed, and eliminating the need for secondary screening before packaging, thereby improving the production efficiency of the feed to ensure the uniformity and quality of the feed.

[0047] The unformed feed enters the injection pipe 7 along the inclined surface of the collecting box 20, and enters the fixed cylinder 4 through the injection pipe 7. As the conveying motor 8 is started, the feed is lifted under the rotation of the auger 13, so that the feed is discharged through the discharge pipe 6 and falls into the feed hopper 2 again, and is extruded and formed by the extrusion device body 3 again. During use, the device can directly perform secondary processing on the unformed feed without manual processing of the unformed feed, thereby improving the feed processing effect.

[0048] When the auger 13 rotates, the limiting plate 12 is driven to rotate, thereby driving the extrusion block 11 to rotate in the fixed cylinder 4, so that the inclined surface of the extrusion block 11 pushes the moving rod 10, driving the moving rod 10 and the extrusion rod 17 to rise in the fixed cylinder 4, and compressing the first spring 9. The rise of the extrusion rod 17 squeezes the water in the connecting pipe 14, so that the water in the connecting pipe 14 pushes the blocking block 27 in the drain pipe 15, so that the blocking block 27 no longer blocks the fixed ring 26, and stretches the second spring 28, so that the water is discharged through the drain pipe 15 and the nozzle 16. Until the water is completely discharged, the internal structure of the drain pipe 15 returns to its original state under the elastic force of the second spring 28, and the sprayed water sprays the feed in the fixed cylinder 4 with water, increases the moisture content of the feed, and avoids the situation where the moisture of the unformed feed is reduced too much after being blown by the drying fan, affecting its re-forming.

[0049] When the squeezing block 11 is separated from the moving rod 10, under the elastic force of the first spring 9, the moving rod 10 and the squeezing rod 17 return to their original state, so that the volume inside the connecting tube 14 becomes larger and the pressure becomes smaller. Therefore, under the action of the pressure, the water in the water storage cylinder 5 pushes the blocking block 27 in the connecting tube 14, so that the blocking block 27 no longer blocks the fixing ring 26 and stretches the second spring 28, so that the water in the water storage cylinder 5 is injected into the connecting tube 14 again until the pressure inside the connecting tube 14 is the same as that outside. The device returns to its original state and prepares for the next addition of water to the feed.

[0050] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
