Description

Technical Field

[0001] This invention relates to the field of feed processing equipment technology, and more specifically to a feed premixing equipment. Background Technology

[0002] In the production of ruminant feed, animals like cattle and sheep have unique digestive systems and extremely stringent feed requirements. Their feed needs to precisely proportion high-fiber ingredients with various trace elements to maintain the ecological balance of rumen microorganisms and promote efficient absorption of nutrients. If there are deviations in the premixing process, resulting in uneven distribution of nutrients, ruminants may experience stunted growth, weakened immunity, and in severe cases, even rumen acidosis and other serious illnesses.

[0003] Currently, the most common type of feed premixing equipment on the market is the single-stage mixing type. When dealing with raw materials with high fiber content, such as alfalfa meal and straw, the fibers easily entangle and aggregate, forming stubborn agglomerates. This makes it difficult for vitamins, minerals, and other trace elements to be evenly distributed. Furthermore, the simple flow field created by single-stage mixing equipment easily generates mixing dead zones within the equipment, making it difficult to achieve an ideal uniform mixing state. Ultimately, this results in low product qualification rates and fails to meet the refined, high-quality production requirements of the modern feed industry.

[0004] Therefore, how to achieve efficient crushing of high-fiber feed and improve the uniformity of mixing while increasing production efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to overcome the problems of uneven mixing and insufficient crushing capacity of traditional feed premixing equipment when processing high-fiber ruminant feed, and to meet the refined and high-quality production needs of the modern feed industry, this application provides a feed premixing equipment.

[0006] The feed premixing equipment provided in this application adopts the following technical solution: A feed premixing device includes a cylinder with a feed inlet at the top and a discharge outlet at the bottom. A drive shaft is rotatably connected inside the cylinder. A feeding device is installed at the top of the cylinder corresponding to the feed inlet, and a discharge device is installed at the bottom of the cylinder corresponding to the discharge outlet. A drive device connected to the drive shaft is mounted on the cylinder. A first stirring assembly and a second stirring assembly are symmetrically arranged on the drive shaft inside the cylinder. A shearing assembly connected to the drive shaft is located inside the cylinder between the first stirring assembly and the second stirring assembly.

[0007] By adopting the above technical solution, a three-stage processing system is formed by the drive shaft linking the first mixing component, the shearing component, and the second mixing component. This system enables the entire process of feed processing, from initial mixing and fiber breaking to deep homogenization. Specifically, the first mixing component powerfully crushes agglomerated materials, the shearing component precisely shears fiber clumps, and the second mixing component promotes mixing. The synergistic effect of these three components solves the problems of "uneven mixing and large particle residue" in traditional equipment, effectively improving mixing uniformity and fiber breakage rate. This system is suitable for the premixing production of ruminant feeds such as high-fiber feeds.

[0008] Furthermore, the feeding device includes a feeding hopper, the bottom of which is fixedly and sealed with a feeding pipe. The feeding pipe is fixedly installed on the top of the cylinder corresponding to the feeding port, and a feeding gate is installed in the middle of the feeding pipe.

[0009] By adopting the above technical solution, and utilizing the combined structure of the feed hopper, feed pipe, and feed gate, controllable conveying of raw materials can be achieved. The feed hopper provides a buffer space to avoid feed impact; the sealed feed pipe prevents dust from escaping; and the feed gate can effectively control the feed speed by adjusting its opening. For example, when processing high-density granular materials, the opening can be reduced to avoid blockage; when processing lightweight powdery materials, the opening can be increased to improve feeding efficiency. This design not only improves feeding accuracy but also helps reduce dust leakage rate, meeting the dual requirements of hygiene and efficiency in feed production.

[0010] Furthermore, the discharge device includes a discharge box fixedly connected to the bottom of the cylinder, the discharge box being sealed and connected to the discharge port, a guide plate being sealed and connected to the end of the discharge box away from the cylinder, the guide plate being hinged to the discharge box, a telescopic member being hinged to the end of the guide plate away from the discharge box, and limit plates being fixedly installed symmetrically on both sides of the discharge box corresponding to the guide plate.

[0011] By adopting the above technical solution, the guide plate driven by the telescopic component and the limiting plate work together to achieve rapid opening and closing of the discharge port. The limiting plate guides the material along the guide plate for discharge. Compared with other discharge designs that use valves or discharge pipes, the guide plate can cover a larger discharge port. After the feed is mixed, the guide plate opens quickly, and under the action of gravity and stirring force, the larger discharge port can empty the material in the cylinder more quickly. This design effectively shortens the discharge time and helps improve production efficiency.

[0012] Furthermore, the driving device includes a driving component, a first transmission gear is fixedly mounted on the output shaft of the driving component, and a second transmission gear is fixedly mounted on one end of the drive shaft that passes through the cylinder, wherein the first transmission gear meshes with the second transmission gear.

[0013] By adopting the above technical solution and utilizing the combination of drive components and gear transmission, efficient power transmission can be achieved, meeting the reliability requirements of industrial production.

[0014] Furthermore, the first stirring assembly includes a first mounting frame, which is fixedly installed inside the cylinder near the feed inlet. The drive shaft is rotatably connected to the first mounting frame. A plurality of first stirring shafts arranged centrally symmetrically are rotatably connected to the first mounting frame. A first stirring paddle is fixedly installed on the first stirring shaft. A first driven grinding gear is fixedly connected to the first stirring shaft. A first driven grinding gear is fixedly installed on the drive shaft corresponding to the first driven grinding gear. The first driven grinding gear meshes with the first driven grinding gear.

[0015] By adopting the above technical solution, multiple centrally symmetrical first stirring shafts operate synchronously in conjunction with the first stirring paddle, enabling all-round stirring of the feed in the early stages of entering the cylinder, quickly disrupting the feed distribution. Simultaneously, the crushing effect generated by the gear transmission driving the first stirring shafts effectively breaks up larger feed particles and clumps, integrating preliminary mixing and crushing functions to improve mixing efficiency and uniformity.

[0016] Furthermore, the second stirring assembly includes a second mounting frame, which is fixedly installed inside the cylinder near the discharge port. The drive shaft is rotatably connected to the second mounting frame. A plurality of second stirring shafts arranged in a centrally symmetrical manner are rotatably connected to the second mounting frame. A second stirring paddle is fixedly installed on the second stirring shaft. A second driven grinding gear is fixedly connected to the second stirring shaft. A second driven grinding gear is fixedly installed on the drive shaft corresponding to the second driven grinding gear. The second driven grinding gear meshes with the second driven grinding gear.

[0017] By adopting the above technical solution, and utilizing the second stirring shaft with a multi-axis centrally symmetrical layout in conjunction with the second stirring paddle, a 360-degree, multi-angle stirring flow field can be formed at the bottom of the cylinder to perform secondary fine mixing of the pre-treated feed, effectively eliminating mixing dead zones, significantly improving the uniformity of the distribution of various components in the feed, and ensuring product quality stability.

[0018] Furthermore, the shearing assembly includes a fixed sleeve, which is fixedly mounted on the drive shaft. Several fixed frames are centrally symmetrically connected to the fixed sleeve along the radial direction of the drive shaft. Sliding frames are slidably connected to the fixed frames. Several equidistant first slits are opened on the fixed frames. Second slits are opened on the sliding frames corresponding to the first slits. A limiting ring is fixedly installed inside the cylinder corresponding to the sliding frames. An annular groove is opened on the inner side of the limiting ring. A wavy driving groove is opened on both sides of the annular groove. A limiting pin is fixedly installed on the sliding frames corresponding to the driving grooves. The limiting pin is slidably connected in the driving grooves.

[0019] By adopting the above technical solution, a compound shearing action is formed by combining the circular motion of the fixed frame with the radial reciprocating sliding of the sliding frame. Compared with single rotary shearing, this can more effectively break up clumps and large particles in the feed, refining and dispersing them, providing a more uniform material base for subsequent mixing processes, and significantly improving the uniformity of feed mixing. Simultaneously, the wave-shaped drive groove design allows the sliding frame to slide continuously, resulting in the first and second cuts constantly intersecting. This continuous shearing of the fibers in the feed through the first and second cuts also avoids the problem of feed clogging the equipment due to prolonged compression during the shearing process. Furthermore, the compound motion causes the feed to flow rapidly within the shearing area, further reducing the risk of clogging and ensuring continuous and stable operation of the equipment.

[0020] Furthermore, a sealing groove is provided on the inner side of the limiting ring, and a sealing ring is slidably connected inside the sealing groove. A sliding hole is provided on the sealing ring corresponding to the sliding frame, and the sliding frame passes through the sliding hole and is slidably connected to the sealing ring.

[0021] By adopting the above technical solution, the double sealing structure effectively prevents feed dust from entering other areas of the equipment, avoiding problems such as component wear and jamming caused by dust accumulation inside the equipment. At the same time, it prevents cross-contamination between different batches of feed, ensuring the stability and safety of feed product quality.

[0022] Furthermore, the inner side of the cylinder is fixedly connected to both the upper and lower ends of the limiting ring. The inner side of the guiding ring is provided with a conical guiding surface, which obliquely connects the inner side of the cylinder and the inner side of the limiting ring.

[0023] By adopting the above technical solution and utilizing the oblique connection design of the guide surface, the steps between the inner wall of the cylinder and the limiting ring are filled, preventing feed from accumulating at these steps and forming dead zones. This ensures that all feed can participate in the shearing and mixing process, improving raw material utilization and product quality consistency.

[0024] Furthermore, a material spreading disc is fixedly installed on the drive shaft between the first stirring assembly and the inner top of the cylinder, and the material spreading disc has a ring of evenly distributed spreading holes.

[0025] By adopting the above technical solution, the feed spreading disc utilizes centrifugal force and the design of the spreading holes to quickly and evenly distribute the feed entering the cylinder to various positions inside the cylinder, avoiding the feed from accumulating below the feed inlet. This provides a more uniform material base for the mixing work of the first mixing component, significantly improving the initial mixing effect of the feed and reducing mixing blind spots and dead angles.

[0026] Beneficial effects achieved: This application achieves comprehensive optimization of feed mixing technology by constructing a three-stage processing system of "mixing-shearing-remixing". The first mixing component, driven by the drive shaft, initially crushes agglomerated materials with high torque; the shearing component precisely breaks down fibers through compound motion; and the second mixing component achieves deep mixing with high-speed mixing. The three components work together to improve the mixing uniformity to an industry-leading level, effectively avoiding animal growth problems caused by uneven nutrition. At the same time, the targeted structural design reduces additional crushing processes, shortens the production cycle, and reduces energy consumption; double sealing ensures reliable operation, and the flow guiding structure optimizes material flow, significantly extending the equipment maintenance cycle. Compared with traditional equipment, this feed premixing equipment achieves higher production efficiency and product quality at a lower cost, providing a reliable guarantee for the refined production of ruminant feed.

[0036] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0037] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present 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, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] This application discloses a feed premixing device.

[0040] Please refer to the above as well. Figures 1 to 8 In one embodiment of this application, a feed premixing device includes a frame 100, a cylinder 101 fixedly mounted on the frame 100, a feed inlet 102 at the top of the cylinder 101, a discharge outlet 103 at the bottom of the cylinder 101, and a drive shaft 104 rotatably connected inside the cylinder 101. A feeding device 200 is installed at the top of the cylinder 101 corresponding to the feed inlet 102, and a discharge device 300 is installed at the bottom of the cylinder 101 corresponding to the discharge outlet 103. A drive device 400 connected to the drive shaft 104 is mounted on the cylinder 101. A first stirring assembly 500 and a second stirring assembly 600 are symmetrically arranged on the drive shaft 104 inside the cylinder 101. A shearing assembly 700 connected to the drive shaft 104 is located inside the cylinder 101 between the first stirring assembly 500 and the second stirring assembly 600.

[0041] During operation, material enters the cylinder 101 through the feed inlet 102 via the feeding device 200. The drive device 400 rotates the drive shaft 104, causing the first stirring component 500 to initially stir the material. The falling material then enters the shearing component 700, which shears and breaks down the fibers in the material, while also refining the particle size and dispersing agglomerates. The pre-treated material is then mixed a second time by the second stirring component 600. The second stirring component 600 and the first stirring component 500 are symmetrically arranged to form opposite radial flow fields during operation, allowing the material to achieve all-round mixing during the cross-radial flow. Finally, the discharge device 300 discharges the pre-mixed feed by controlling the opening of the discharge port 103. This three-stage processing mode of "stirring-shearing-re-stirring" effectively solves the problems of uneven mixing and difficulty in dispersing large particles in traditional premixing equipment through flow field optimization and the synergistic effect of mechanical force.

[0042] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the feeding device 200 includes a feeding hopper 201, a feeding pipe 202 is fixedly and sealed to the bottom of the feeding hopper 201, the feeding pipe 202 is fixedly installed on the top of the cylinder 101 corresponding to the feeding port 102, and a feeding gate 203 is installed in the middle of the feeding pipe 202.

[0043] During operation, raw materials are temporarily stored and initially guided through the feed hopper 201, and then vertically conveyed to the feed inlet 102 at the top of the cylinder 101 via the bottom-sealed feed pipe 202. Feeding can be started or stopped by controlling the opening and closing of the feed gate 203 located in the middle of the feed pipe 202. When the gate is open, the raw materials fall freely into the cylinder 101 under gravity; when the gate is closed, the feed channel is immediately blocked, stopping the material conveying. This device controls the feeding speed and feed volume by adjusting the opening frequency and degree of the feed gate 203.

[0044] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the discharge device 300 includes a discharge box 301 fixedly connected to the bottom of the cylinder 101. The discharge box 301 is sealed and connected to the discharge port 103. A guide plate 302 is sealed and connected to the end of the discharge box 301 away from the cylinder 101. The guide plate 302 is hinged to the discharge box 301. A telescopic member 303 is hinged to the end of the guide plate 302 away from the discharge box 301. The end of the telescopic member 303 away from the guide plate 302 is hinged to the frame 100. Limiting plates 304 are symmetrically fixedly installed on both sides of the discharge box 301 corresponding to the guide plate 302.

[0045] During operation, the telescopic component 303 generates thrust or pull by extending or shortening, which in turn drives the hinged guide plate 302 to rotate around the hinge point with the discharge box 301. After the feed is mixed in the cylinder 101, when the telescopic component 303 extends, it pushes the guide plate 302 to rotate around the hinge point and open, at which point the discharge box 301 is connected to the outside. Under the action of gravity, the feed in the cylinder is smoothly discharged through the discharge port 103, the discharge box 301, and the guide plate 302. After the mixed feed is discharged, the telescopic component 303 shortens, pulling the guide plate 302 to rotate in the opposite direction around the hinge point to close and reseal the discharge box 301. The limiting plate 304 restricts the material from flowing out from both sides of the guide plate 302, ensuring that the premixed material flows out reliably along the inclined direction of the guide plate 302.

[0046] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the telescopic component 303 is configured as an electric telescopic rod. Using the electric telescopic rod as the telescopic component 303 enables precise electric control and intelligent adjustment of the feed guide plate 302, and the electric telescopic rod has high stroke control accuracy. During use, the opening angle of the feed guide plate 302 can be set via a PLC program to adapt to the flowability requirements of different feeds.

[0047] It is understood that in other embodiments of this application, the telescopic member 303 may also be a device or apparatus such as a hydraulic cylinder or a pneumatic cylinder that can drive the guide plate 302 to swing.

[0048] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the drive device 400 includes a drive member 401, a first transmission gear 402 is fixedly mounted on the output shaft of the drive member 401, and a second transmission gear 403 is fixedly mounted on one end of the drive shaft 104 that passes through the cylinder 101, and the first transmission gear 402 meshes with the second transmission gear 403.

[0049] During operation, when the drive unit 400 is started, the drive component 401 begins to operate, and its output shaft drives the first transmission gear 402 to rotate. Since the first transmission gear 402 meshes with the second transmission gear 403, through the meshing principle of gear transmission, the rotation of the first transmission gear 402 transmits power to the second transmission gear 403, thereby driving the drive shaft 104, which is fixedly connected to the second transmission gear 403, to rotate synchronously within the cylinder 101. The rotation of the drive shaft 104 further drives the first stirring assembly 500, the second stirring assembly 600, and the shearing assembly 700 mounted on it to begin working, realizing the stirring, shearing, and mixing of the feed within the cylinder.

[0050] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the drive component 401 is configured as an electric motor, which is fixedly mounted on the frame 100. As the drive component 401, the electric motor provides power to the feed premixing equipment by means of the principle of converting electrical energy into mechanical energy.

[0051] During operation, when the motor is powered on, the stator windings generate a rotating magnetic field based on the principle of electromagnetic induction. This magnetic field interacts with the rotor windings, driving the rotor to rotate and transmitting power to the first transmission gear 402 fixed on the output shaft. The first transmission gear 402 meshes with the second transmission gear 403 on the drive shaft 104, thereby driving the drive shaft 104 to rotate within the cylinder 101. This causes the first stirring assembly 500, the second stirring assembly 600, and the shearing assembly 700 mounted on the drive shaft 104 to operate synchronously, achieving stirring, shearing, and mixing of the feed. By adjusting the power supply parameters such as the motor's voltage and frequency, the speed and direction of the drive shaft can be precisely controlled to adapt to different feed mixing process requirements.

[0052] Please refer to the above as well. Figures 1 to 8In one specific embodiment of this application, the first stirring assembly 500 includes a first mounting frame 501, which is fixedly installed inside the cylinder 101 near the feed inlet 102. The drive shaft 104 is rotatably connected to the first mounting frame 501. A plurality of first stirring shafts 502 arranged centrally symmetrically are rotatably connected to the first mounting frame 501. A first stirring paddle 503 is fixedly installed on the first stirring shaft 502. A first driven grinding gear 504 is fixedly connected to the first stirring shaft 502. A first driven grinding gear 505 is fixedly installed on the drive shaft 104 corresponding to the first driven grinding gear 504. The first driven grinding gear 504 meshes with the first driven grinding gear 505.

[0053] During operation, when the drive unit 400 drives the drive shaft 104 to rotate, the first active crushing gear 505 fixed on the drive shaft 104 rotates accordingly. Since the first driven crushing gear 504 meshes with the first active crushing gear 505, the first active crushing gear 505 drives the first driven crushing gear 504 to rotate via gear transmission, thereby causing the first stirring shaft 502, which is fixedly connected to the first driven crushing gear 504, to begin rotating. Multiple centrally symmetrically arranged first stirring shafts 502 rotate synchronously, and the first stirring paddles 503 mounted on them stir the feed entering the cylinder 101 from the feed inlet 102, causing the feed to form an initial circulating motion within the cylinder. During this process, the first stirring paddles 503 play a mixing role, and the first driven crushing gear 504 and the first active crushing gear 505 not only transmit power but also crush larger particles in the feed, breaking up clumps and preparing for subsequent mixing processes.

[0054] In one specific embodiment of this application, the transmission ratio between the first driven grinding gear 504 and the first driving grinding gear 505 is I, satisfying I > 1.

[0055] During operation, when the transmission ratio I between the first driven grinding gear 504 and the first driving grinding gear 505 is greater than 1 (i.e., I = number of teeth on the driven gear / number of teeth on the driving gear > 1), the transmission structure is a reduction transmission. The first driven grinding gear 504 obtains greater torque through reduction, driving the first stirring shaft 502 and the first stirring paddle 503 to operate in a "low speed, high torque" mode, generating stronger grinding and shearing forces on agglomerated and large-particle raw materials in the feed. When the speed of the driving shaft 104 is 300 rpm and I = 2, the speed of the first stirring shaft 502 drops to 150 rpm, but the torque increases to twice that of the driving shaft, effectively ensuring the mixing force of the first stirring paddle 503.

[0056] Please refer to the above as well. Figures 1 to 8In one specific embodiment of this application, the second stirring assembly 600 includes a second mounting bracket 601, which is fixedly installed inside the cylinder 101 near the discharge port 103. The drive shaft 104 is rotatably connected to the second mounting bracket 601. A plurality of second stirring shafts 602 arranged centrally symmetrically are rotatably connected to the second mounting bracket 601. A second stirring paddle 603 is fixedly installed on the second stirring shaft 602. A second driven grinding gear 604 is fixedly connected to the second stirring shaft 602. A second driven grinding gear 605 is fixedly installed on the drive shaft 104 corresponding to the second driven grinding gear 604. The second driven grinding gear 604 and the second driven grinding gear 605 mesh.

[0057] During operation, when the drive unit 400 drives the drive shaft 104 to rotate, the second active grinding gear 605 fixed on the drive shaft 104 rotates accordingly. Since the second driven grinding gear 604 meshes with the second active grinding gear 605, the rotation of the second active grinding gear 605 drives the second driven grinding gear 604 to rotate via gear transmission, thereby causing the second stirring shaft 602, which is fixedly connected to the second driven grinding gear 604, to rotate synchronously. Multiple centrally symmetrically arranged second stirring shafts 602 drive their respective second stirring paddles 603 to stir the feed in the bottom area of ​​the cylinder 101. At this time, the feed, after preliminary mixing by the first stirring component 500 and processing by the shearing component 700, falls into this area, where the second stirring paddles 603 further stir, mix, and disperse it, ensuring that the various components in the feed are fully and evenly distributed, and finally discharged through the discharge port 103.

[0058] In one specific embodiment of this application, the transmission ratio between the second driven grinding gear 604 and the second driving grinding gear 605 is i, satisfying i≤1.

[0059] During operation, since the transmission ratio i ≤ 1, the rotational speed of the second driven grinding gear 604 is greater than or equal to the rotational speed of the second driving grinding gear 605. The rotation of the second driving grinding gear 605 drives the second driven grinding gear 604 to rotate through gear transmission, thereby causing the second stirring shaft 602, which is fixedly connected to the second driven grinding gear 604, to rotate synchronously. Multiple centrally symmetrically arranged second stirring shafts 602 drive their respective second stirring paddles 603 to perform high-speed stirring of the feed in the bottom area of ​​the cylinder 101. At this time, the feed, which has been preliminarily mixed by the first stirring component 500 and processed by the shearing component 700, falls into this area, where the high-speed rotating second stirring paddles 603 further rapidly stir, mix, and disperse it, so that the various components in the feed are fully and evenly mixed in a short time.

[0060] Please refer to the above as well. Figures 1 to 8In one specific embodiment of this application, the blades of the first stirring paddle 503 and the second stirring paddle 603 are both arranged obliquely, and the first stirring paddle 503 and the second stirring paddle 603 are symmetrically arranged inside the cylinder 101.

[0061] It is understandable that when the drive shaft 104 drives the blades of the first stirring paddle 503 and the second stirring paddle 603 to rotate in the same direction, the first stirring paddle 503 and the second stirring paddle 603 will stir the material in opposite directions to form a reverse flow field. When the drive shaft 104 rotates in the forward direction, the first stirring paddle 503 and the second stirring paddle 603 can stir the material towards the shearing component 700 in the middle of the cylinder 101. When the drive shaft 104 rotates in the reverse direction, the first stirring paddle 503 and the second stirring paddle 603 can stir the material towards both ends of the cylinder 101.

[0062] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, the shearing assembly 700 includes a fixed sleeve 701, which is fixedly mounted on the drive shaft 104 between the first stirring assembly 500 and the second stirring assembly 600. A plurality of fixed frames 702 are centrally symmetrically fixedly connected to the fixed sleeve 701 along the radial direction of the drive shaft 104. A sliding frame 703 is slidably connected to the fixed frame 702. A plurality of equidistantly distributed first cuts 704 are provided on the fixed frame 702. A second cut 705 is provided on the sliding frame 703 corresponding to the first cuts 704. A limiting ring 706 is fixedly installed inside the cylinder 101 corresponding to the sliding frame 703. An annular groove 707 is provided on the inner side of the limiting ring 706. A wavy driving groove 708 is provided on both sides of the annular groove 707. A limiting pin 709 is fixedly installed on the sliding frame 703 corresponding to the driving groove 708. The limiting pin 709 is slidably connected in the driving groove 708.

[0063] During operation, when the drive shaft 104 rotates under the drive of the drive device 400, the fixed sleeve 701 rotates accordingly, and the fixed bracket 702 on the fixed sleeve 701 performs a circular motion synchronously. The sliding bracket 703 is slidably engaged with the wave-shaped drive grooves 708 on both sides of the inner surface annular groove 707 of the limiting ring 706 via the limiting pin 709. During the circular motion of the fixed bracket 702, the limiting pin 709 slides along the wave-shaped drive groove 708. Because the drive groove 708 is wave-shaped, the limiting pin 709 forces the sliding bracket 703 to reciprocate along the radial direction of the drive shaft 104 on the fixed bracket 702 during the sliding process. When the feed falls from the first mixing component 500 to the shearing component 700 area, with the movement of the fixed frame 702 and the sliding frame 703, the first cut 704 and the second cut 705 on the fixed frame 702 and the sliding frame 703 will continuously intersect, shearing and breaking up clumps and large particles in the feed; at the same time, the combined motion of circumferential motion and radial sliding causes the feed to be subjected to multi-directional forces in this area, achieving breaking and dispersing. The broken feed then falls to the second mixing component 600 for further mixing.

[0064] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, a sealing groove 710 is provided on the inner side of the limiting ring 706, and a sealing ring 711 is slidably connected inside the sealing groove 710. A sliding hole 712 is provided on the sealing ring 711 corresponding to the sliding frame 703, and the sliding frame 703 passes through the sliding hole 712 and is slidably connected to the sealing ring 711.

[0065] During operation, when the drive shaft 104 drives the fixed frame 702 and the sliding frame 703 to perform circular and radial sliding motions, the sliding frame 703 slides within the sliding hole 712 of the sealing ring 711, while the sealing ring 711 slides within the sealing groove 710 on the inner side of the limiting ring 706. This design forms a double sealing structure: on the one hand, the sealing sliding of the sealing ring 711 and the sealing groove 710 prevents feed dust from entering the limiting ring 706 from the gap between the limiting ring 706 and the sliding frame 703; on the other hand, the sealing sliding of the sliding frame 703 and the sliding hole 712 further prevents feed dust from entering the limiting ring 706 along the sliding path of the sliding frame 703. During the operation of the shearing assembly 700, the feed is sheared and crushed at the cut of the fixed frame 702 and the sliding frame 703, and the sealing structure ensures that the dust generated during the crushing process is confined to the shearing area and does not spread to other parts of the equipment, ensuring the cleanliness of the internal environment of the equipment and the normal operation of each component.

[0066] Please refer to the above as well. Figures 1 to 8In one specific embodiment of this application, a guide ring 713 is fixedly connected to both the upper and lower ends of the limiting ring 706 inside the cylinder 101. The inner side of the guide ring 713 is provided with a conical guide surface 714, which obliquely connects the inner side of the cylinder 101 and the inner side of the limiting ring 706.

[0067] During operation, as the feed flows within the cylinder, the guide rings 713 located at the upper and lower ends of the limiting ring 706 function through their conical guide surfaces 714. When the feed falls from above, the guide surface 714 of the upper guide ring 713 smoothly guides the feed from the inner wall of the cylinder 101 to the shearing zone within the limiting ring 706, preventing feed accumulation or dead zones in the transition area. After being processed by the shearing component 700, the feed falls again, and the guide surface 714 of the lower guide ring 713 smoothly guides it from within the limiting ring 706 to the area of ​​the second stirring component 600 at the bottom of the cylinder 101. The inclined design of the guide surface 714 ensures that the feed receives continuous guiding force during flow, maintaining smooth flow and reducing flow resistance and material accumulation.

[0068] Please refer to the above as well. Figures 1 to 8 In one specific embodiment of this application, a spreading disc 800 is fixedly installed on the drive shaft 104 between the first stirring assembly 500 and the inner top of the cylinder 101. The spreading disc 800 has spreading holes 801 evenly distributed in an annular pattern.

[0069] During operation, when the drive shaft 104 rotates under the drive of the drive device 400, the spreading disc 800, fixedly mounted on the drive shaft 104, rotates synchronously. Feed enters the cylinder 101 through the feeding device 200 and falls directly onto the spreading disc 800. As the spreading disc 800 rotates at high speed, the feed on the disc is scattered through the annularly distributed spreading holes 801 under centrifugal force. The scattered feed is dispersed into different areas inside the cylinder 101, and then enters the first stirring assembly 500 below for stirring and mixing, thus completing the initial processing of the feed from the inlet 102 to its uniform distribution within the cylinder 101.

[0070] The implementation principle of a feed premixing device according to an embodiment of this application is as follows: This application utilizes a design concept of graded processing and synergistic efficiency to achieve highly efficient operation of the entire feed process from feeding and mixing to discharging. After the material enters the cylinder 101 through the feeding device 200, the spreading disc 800 evenly disperses the material into the cylinder 101. The first mixing component 500 uses a high-torque mode with deceleration transmission to initially mix and crush the feed. Subsequently, the shearing component 700, through the interlacing of cutting edges in a compound motion, can both shear and crush the fibers in the raw material and further refine and disperse large particles. Finally, the second mixing component 600 rotates at high speed to form a reverse flow field, achieving deep mixing of the material. During this process, the guide ring 713 optimizes the feed flow path, the sealing structure prevents material interference during operation, and the discharging device 300 precisely controls the discharging rhythm through the telescopic component 303. The components work closely together through mechanical transmission and structural innovation, solving the problems of uneven mixing and difficulty in fiber dispersion in traditional equipment, while also reducing maintenance costs through modular design, meeting the multiple requirements of feed production for efficiency and quality.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
