Description

Technical Field

[0001] This invention relates to the field of feed processing technology, and in particular to a pelleting device for feed processing. Background Technology

[0002] Feed is a general term for the food consumed by livestock. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Pelleted feed is a type of feed that is nutritionally complete, highly stable, does not easily break down in water, does not easily pollute water bodies, is easy to digest and absorb, and saves farmers labor and effort, making it popular among aquaculture farmers.

[0003] Pellet mills are used in the manufacturing process of pelleted feed. Existing pellet mills generally extrude the raw material first, then cut the feed at the extrusion point, and finally heat the cut feed pellets to harden them, thus obtaining feed pellets. However, during the process of extrusion and hardening, the feed is in a soft state and is easily deformed. This can easily lead to problems such as the formed feed pellets being not full and having inconsistent shapes. Therefore, improvements have been made. Summary of the Invention

[0012] Preferably, the heating component is a heating ring disposed below the disk, which surrounds the outside of multiple connecting pipes.

[0013] Preferably, the top end of the heating ring is rotatably connected to a fixed disc that is fixedly sleeved on multiple connecting pipes, a gear ring is fixedly sleeved on the heating ring, and a flat gear that can mesh with the gear ring is fixedly sleeved on the split shaft.

[0014] Compared with the prior art, the present invention provides a pelleting device for feed processing, which has the following beneficial effects:

[0015] 1. A pelleting device for feed processing, comprising a pelleting tube and a connecting tube, wherein an extrusion assembly extrudes feed from the cylinder into the discharge tube and into the pelleting tube, and then the feed enters the connecting tube from the pelleting tube. Subsequently, an assembly that drives the split shaft to rotate drives the split shaft to rotate, and the split shaft synchronously drives the sleeve and the dividing blade to rotate. The dividing blade passes between the pelleting tube and the connecting tube and cuts the feed in the middle. The resulting feed pellets fall vertically along the connecting tube and are heated, dried, hardened and shaped at that point, ultimately forming feed pellets that fall to the ground.

[0016] 2. A pelleting device for feed processing, wherein feed pellets fall from the connecting pipe into the speed reduction tube by setting a curved speed reduction tube, and fall along the curved speed reduction tube, which can slow down the falling time of the feed pellets, thereby allowing the interior of the feed pellets to be fully dried and hardened. Furthermore, the feed pellets can undergo a certain degree of impact, collision and mutual friction within the speed reduction tube, thereby making the surface of the feed pellets smoother and flatter.

[0017] 3. A pelleting device for feed processing, wherein a fan blade is provided, and when the split shaft rotates, it synchronously drives the second bevel gear to rotate. The second bevel gear meshes with and drives the first bevel gear to rotate. The first bevel gear synchronously drives the connecting shaft and the fan blade to rotate. The rotating fan blade blows air towards the bottom outlet of the speed reduction tube, thereby allowing the hot airflow in the speed reduction tube to flow fully, making it dry evenly, increasing the collision and friction between feed pellets, and delaying the falling time of feed pellets, so that they are dried thoroughly.

[0018] 4. A pelleting device for feed processing, which is equipped with a detachable dividing blade. The blade handle of the dividing blade is inserted into the slot, and the knob is tightened into the threaded hole so that its bottom end is inserted into the circular groove, thereby fixing and installing the dividing blade. This allows for easy assembly and disassembly of the dividing blade. By installing different numbers of dividing blades at equally divided positions around the circumference, the length of the feed pellets can be adjusted. As shown in the figure, dividing blades can be installed at five or ten equal divisions.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Example

[0032] Reference Figure 1-8A pelleting device for feed processing includes a cylinder 1 with a feeding pipe 19 at its top, a discharge pipe 3 at its bottom, a pair of support legs 2 fixed to the outer circumference of the cylinder 1, a dense array of pelleting pipes 4 at the bottom of the discharge pipe 3, a disc 6 below the discharge pipe 3, and the discharge pipe 3 and the disc 6 being fixed together by a connector 5. A dense array of connecting pipes 7 are fixed through the disc 6, and a heating element is installed at each connecting pipe 7. The connecting pipes 7 correspond one-to-one with the pelleting pipes 4. A fixing block 9 is fixed to the outer wall of the cylinder 1, and a split shaft 10 is rotatably connected to the fixing block 9. A sleeve disc 11 is fixedly sleeved on the split shaft 10. A plurality of dividing blades 12 are arranged in a ring array on the outer circumference of the sleeve disc 11. It passes right between the granulation tube 4 and the connecting tube 7. An extrusion assembly is installed inside the cylinder 1, and an assembly that drives the split shaft 10 to rotate is installed on the cylinder 1. The pre-mixed feed is added into the cylinder 1 through the feeding tube 19. The extrusion assembly squeezes the feed from the cylinder 1 into the discharge tube 3 and into the granulation tube 4. Then the feed enters the connecting tube 7 from the granulation tube 4. The assembly that drives the split shaft 10 to rotate drives the split shaft 10 to rotate. The split shaft 10 synchronously drives the sleeve 11 and the dividing blade 12 to rotate. The dividing blade 12 passes between the granulation tube 4 and the connecting tube 7, cutting the feed in the middle. The resulting feed pellets fall vertically along the connecting tube 7 and are heated, dried, hardened, and shaped at that point, finally forming feed pellets that fall down.

[0033] Furthermore, the extrusion assembly includes a main shaft 13 rotatably connected to the top of the cylinder 1, a spiral feed plate 14 mounted on the main shaft 13, a motor 15 fixed to the top of the cylinder 1, and the output shaft of the motor 15 connected to the end of the main shaft 13. When the motor 15 is started, the output shaft of the motor 15 drives the main shaft 13 and the spiral feed plate 14 to rotate, and the rotating spiral feed plate 14 pushes the feed towards the discharge pipe 3 side for extrusion.

[0034] Furthermore, the components that drive the rotation of the split shaft 10 include a first pulley 16 and a second pulley 17 respectively fixedly sleeved on the main shaft 13 and the split shaft 10. The same belt 18 is sleeved between the first pulley 16 and the second pulley 17. When the main shaft 13 rotates, it synchronously drives the first pulley 16 to rotate, and then drives the split shaft 10 to rotate through the second pulley 17 and the belt 18.

[0035] Furthermore, a deceleration pipe 8 is provided below the connecting pipe 7. The bottom ends of multiple connecting pipes 7 are connected to the deceleration pipe 8. The deceleration pipe 8 has a curved structure. The feed pellets fall from the connecting pipe 7 into the deceleration pipe 8 and fall along the curved deceleration pipe 8, which slows down the falling speed of the feed pellets, thereby allowing the interior of the feed pellets to be fully dried and hardened. In addition, the feed pellets can undergo a certain degree of impact, collision and mutual friction within the deceleration pipe 8, thereby making the surface of the feed pellets smoother and flatter.

[0036] Furthermore, a hanging rod 20 is fixed on the deceleration pipe 8, and a connecting shaft 21 is rotatably connected to the hanging rod 20. A fan blade 22 is fixed at the end of the connecting shaft 21, facing the bottom outlet of the deceleration pipe 8. A first bevel gear 23 and a second bevel gear 24 are respectively fixedly sleeved at the adjacent ends of the connecting shaft 21 and the branch shaft 10. The first bevel gear 23 and the second bevel gear 24 are meshed and connected. When the branch shaft 10 rotates, it synchronously drives the second bevel gear 24 to rotate. The second bevel gear 24 meshes and drives the first bevel gear 23 to rotate. The first bevel gear 23 synchronously drives the connecting shaft 21 and the fan blade 22 to rotate. The rotating fan blade 22 blows air towards the bottom outlet of the deceleration pipe 8, thereby allowing the hot airflow in the deceleration pipe 8 to flow fully, making it dry evenly, increasing the collision and friction between feed particles, and delaying the falling time of feed particles, so that they are dried fully.

[0037] Furthermore, the outer circumference of the sleeve 11 is provided with multiple ring-shaped arrays of insert sleeves 25, each with a slot 26 at its end. The handle of the dividing blade 12 is inserted into the slot 26. The insert sleeve 25 is provided with a component for fixing the handle. By inserting the handle of the dividing blade 12 into the slot 26 and then fixing the dividing blade 12 with the component for fixing the handle, the dividing blade 12 can be easily installed and removed. By installing different numbers of dividing blades 12 at equally spaced positions on the circumference, the length of the feed pellets can be adjusted. Figure 4 As shown, dividing blades 12 can be installed at the five-eighths and tenths of the division.

[0038] Furthermore, the component for fixing the handle includes a circular groove 27 on the handle and a threaded hole 28 on the sleeve 25. A knob 29 that can be inserted into the circular groove 27 is threaded into the threaded hole 28. After inserting the handle of the dividing knife 12 into the slot 26, the knob 29 is tightened into the threaded hole 28 so that its bottom end is inserted into the circular groove 27, thereby fixing and installing the dividing knife 12.

[0039] Furthermore, the heating component is a heating ring 31 located below the disc 6. The heating ring 31 surrounds the outside of multiple connecting pipes 7. The heating ring 31 heats the connecting pipes 7, causing the surface of the feed pellets to harden rapidly and form pellets.

[0040] Furthermore, a fixed disk 30 is rotatably connected to the top of the heating ring 31 and fixedly sleeved on multiple connecting pipes 7. A gear ring 32 is fixedly sleeved on the heating ring 31, and a spur gear 33 that can mesh with the gear ring 32 is fixedly sleeved on the split shaft 10. When the split shaft 10 rotates, it synchronously drives the spur gear 33 to rotate. The spur gear 33 meshes and drives the gear ring 32 to rotate. The gear ring 32 synchronously drives the heating ring 31 to rotate, thereby making the multiple connecting pipes 7 more evenly heated.

[0041] Working principle: When the motor 15 is started, the output shaft of the motor 15 drives the main shaft 13 and the spiral feeding plate 14 to rotate. The rotating spiral feeding plate 14 pushes the feed to the side of the discharge pipe 3 and squeezes it into the granulation pipe 4. Then the feed enters the connecting pipe 7 from the granulation pipe 4. When the main shaft 13 rotates, it drives the first pulley 16 to rotate synchronously. Then, through the second pulley 17 and the belt 18, it drives the branch shaft 10 to rotate. The branch shaft 10 drives the sleeve 11 and the dividing knife 12 to rotate synchronously. The dividing knife 12 passes between the granulation pipe 4 and the connecting pipe 7 and cuts the feed in the middle. The resulting feed pellets fall vertically along the connecting pipe 7 and are heated, dried and hardened at that point. Finally, the feed pellets fall into the deceleration pipe 8 from the connecting pipe 7. Falling along the curved deceleration pipe 8 slows down the falling time of the feed pellets, so that the inside of the feed pellets can be fully dried and hardened. In addition, the feed pellets can undergo a certain degree of impact, collision and friction within the deceleration pipe 8, making the surface of the feed pellets smoother and flatter.

[0042] When the split shaft 10 rotates, it synchronously drives the second bevel gear 24 to rotate. The second bevel gear 24 meshes and drives the first bevel gear 23 to rotate. The first bevel gear 23 synchronously drives the connecting shaft 21 and the fan blade 22 to rotate. The rotating fan blade 22 blows air towards the bottom outlet of the speed reduction tube 8, thereby allowing the hot airflow in the speed reduction tube 8 to flow fully, making it dry evenly, increasing the collision and friction between feed particles, and delaying the falling time of feed particles, so that they are dried fully.

[0043] Insert the handle of the dividing blade 12 into the slot 26, tighten the knob 29 into the threaded hole 28, and insert its bottom end into the circular groove 27 to fix the dividing blade 12 in place. This allows for easy assembly and disassembly of the dividing blade 12. By installing different numbers of dividing blades 12 at equally spaced circumference positions, the length of the feed pellets can be adjusted. Figure 4 As shown, dividing blades 12 can be installed at the five-eighths and tenths division points;

[0044] When the split shaft 10 rotates, it synchronously drives the spur gear 33 to rotate. The spur gear 33 meshes and drives the gear ring 32 to rotate. The gear ring 32 synchronously drives the heating ring 31 to rotate, thereby making the multiple connecting pipes 7 more evenly heated.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
