Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feed production equipment, in particular to a granulating device for feed production. BACKGROUND

[0002] At present, the demand for high-quality feed is growing rapidly with the vigorous development of animal husbandry. Pollen and grass, as high-quality feed raw materials containing rich nutrients, contain protein, vitamins, minerals and various bioactive substances, which have a positive effect on animal growth and development, immune enhancement, etc. However, pollen and grass in their natural state have many factors that are not conducive to animal feeding and digestion. Pollen particles are small and sticky, which can easily adhere to the oral cavity and digestive tract of animals during feeding, affecting the feeding experience and being difficult to be fully digested; the long fibers of grass directly fed will cause difficulty in chewing for animals, and the long fibers are also not conducive to intestinal peristalsis and digestion and decomposition, so processing them into granular feed is a key way to improve their utilization value.

[0003] At present, the feed granulating device generally consists of a feeding system, a cutting and crushing system, a mixing system, a granulating system and a discharging system, which work together to realize the continuous production process from raw materials to finished granular feed. This conventional granulating device can efficiently complete the processing task when facing ordinary feed raw materials. However, when processing special raw materials such as pollen and grass, it exposes a series of difficult problems.

[0004] Taking the cutting and crushing system as an example, the long fiber characteristics of grass pose a great challenge to ordinary cutting devices. Common cutting blades are difficult to cut long fiber grass to the appropriate length at one time, resulting in uneven size of crushed grass particles. These grass particles that do not meet the particle size requirements will seriously affect the granulation quality in the subsequent granulation process. On the one hand, larger particles of grass are difficult to mix evenly with other raw materials during granulation, which will cause the nutrient distribution of the final granular feed to be unbalanced; on the other hand, uneven particles will cause inconsistent particle density during extrusion molding, affecting the appearance and hardness of the particles, reducing the stability of the feed during storage and transportation, and even causing the particles to break, thereby affecting the quality and market competitiveness of the feed.

[0005] Therefore, the present application provides a granulating device for feed production to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The application provides a granulating device for feed production, aiming at solving the problems of the existing feed granulating device in the background art, such as the long fiber of the grass, which is difficult to be crushed to the appropriate size by the ordinary cutting device, resulting in poor granulating quality.

[0007] To achieve the above object, the application provides the following technical scheme: a granulating device for feed production, comprising a machine box, a first feeding hopper arranged on one side of the machine box, and a crushing mechanism arranged in the interior of the machine box; further comprising a mixing system connected with the crushing mechanism, a granulating system connected with the mixing system, and a discharge pipe fixedly plugged on the machine box and connected with the granulating system.

[0008] In order to facilitate the crushing of the grass, a cutting mechanism for cutting the grass is arranged between the first feeding hopper and the crushing mechanism, the cutting mechanism comprising a rotating rod rotatably plugged on the first feeding hopper, a plurality of knife holders arranged in a ring shape and fixedly arranged on the rotating rod, a blade fixedly installed on the knife holder, a reinforcing plate fixedly installed in the first feeding hopper and matched with the blade, and a first motor for driving the rotating rod to rotate.

[0009] Preferably, in order to improve the cutting efficiency of the grass, the blade is serrated. The serrated blade greatly enhances the cutting ability. Compared with the ordinary flat blade, the serrated design increases the contact points and shearing force of the blade and the grass. At the same speed, the long-fiber grass can be cut off more quickly and effectively, greatly improving the cutting efficiency.

[0010] Preferably, in order to prevent the blockage of the raw materials in the interior of the first feeding hopper, a conveying belt is arranged at the bottom of the first feeding hopper, the conveying belt is in the same horizontal plane as the reinforcing plate, and the shaft of the conveying belt is connected with the rotating rod through a synchronizer. Through the continuous conveying effect, the continuity of feeding is improved, the downtime caused by blockage is reduced, and the whole feed processing process is more efficient and stable. At the same time, the conveying belt and the reinforcing plate are in the same horizontal plane, which ensures the stability of the grass during conveying and further improves the cutting effect.

[0011] Preferably, in order to improve the conveying efficiency, the surface of the conveying belt is further provided with anti-skid protrusions. The anti-skid protrusions make the grass more stable during conveying, and the sliding or deviation of the grass is avoided, so that the grass can be accurately and stably conveyed into the cutting and crushing mechanism.

[0012] Preferably, the crushing mechanism comprises a crushing box fixedly arranged in the interior of the machine box and communicated with the first feeding hopper, a rotating shaft rotatably inserted into the crushing box, a plurality of supports arranged on the rotating shaft at equal intervals, and hammer blades fixedly installed on the supports, a filter screen arranged on the bottom of the crushing box corresponding to the lower part of the hammer blades, the crushing box being communicated with the mixing system through a pipeline, and the rotating shaft being provided with a synchronizer connected with the rotating rod. The rotating rod and the rotating shaft are connected through the synchronizer, and the use of the driving member is reduced. After the forage grass is cut by the cutting mechanism and falls into the interior of the crushing box, the forage grass is broken by the high-speed rotating hammer blades.

[0013] Preferably, the synchronizer comprises synchronizer gears fixedly sleeved on the rotating rod and the rotating shaft respectively, and a synchronizer belt sleeved on the two synchronizer gears and engaged with the two synchronizer gears. One first motor can drive the rotating rod of the cutting mechanism and the rotating shaft of the crushing mechanism at the same time, the use of additional driving motors is reduced, the equipment cost and energy consumption are reduced, the coordination of the cutting and crushing processes in speed is ensured, and the stability and efficiency of the whole feed processing process are improved.

[0014] Preferably, in order to further improve the crushing effect on the forage grass, a plurality of toothed plates are fixedly connected on the inner wall of the crushing box at equal intervals. The hammer blades further crush the forage grass in cooperation with the fixed toothed plates during high-speed rotation. The high-speed impact of the hammer blades causes strong friction between the forage grass and the toothed plates, and the forage grass is gradually crushed into small particles through repeated collision and friction between the hammer blades and the toothed plates. The toothed plates increase the collision and friction area of the forage grass during the crushing process, so that the forage grass not only acts on the hammer blades, but also fully rubs with the toothed plates, and the particles are further refined.

[0015] Preferably, in order to facilitate the installation of the first motor, a motor rack is fixedly arranged on the machine box, the first motor is fixedly installed on the motor rack through bolts, and the output end of the first motor is fixedly connected with the end of the rotating shaft. The motor rack fixedly arranged on the crushing box facilitates the installation of the first motor. The first motor is fixed on the motor rack through bolts, which not only is firm in installation, but also facilitates the disassembly, maintenance or replacement of the first motor when needed.

[0016] Preferably, in order to facilitate the separate grinding of the pollen, the machine box is provided with a crushing mechanism for separately grinding the pollen, the crushing mechanism comprising a second feeding hopper fixedly inserted on the other side of the machine box, a crushing box fixedly arranged in the machine box and communicating with the second feeding hopper, a movable grinding disc rotatably arranged at the bottom of the crushing box, a fixed grinding disc fixedly arranged in the crushing box for matching with the movable grinding disc, and a conical tube fixedly inserted on the fixed grinding disc for guiding the pollen into the space between the fixed grinding disc and the movable grinding disc, the conical tube being inserted with a driving shaft fixedly connected with the movable grinding disc at the fixed grinding disc, the top of the driving shaft penetrating through the top wall of the crushing box and the machine box, a second motor being fixedly mounted on the machine box, and the output end of the second motor being fixedly connected with the end of the driving shaft. The gentle grinding of the pollen is realized through the cooperation of the movable grinding disc and the fixed grinding disc, and the driving of the second motor and the driving shaft. This special grinding method can refine the pollen particles to a suitable size under the premise of ensuring that the nutritional components of the pollen are not lost, meeting the requirements of mixing with the ground forage grass and subsequent granulation.

[0017] Preferably, in order to prevent the pollen from being blocked in the second feeding hopper, a spiral propeller is rotatably inserted at the bottom of the second feeding hopper, and a third motor is fixedly mounted on the outside of the second feeding hopper, with the output end of the third motor being fixedly connected with the shaft of the spiral propeller. The continuous rotation of the spiral propeller keeps the pollen moving slowly and stably in the feeding hopper, avoiding the blocking problem caused by the accumulation and caking of the pollen due to its high viscosity.

[0018] The present application preliminarily cuts the forage grass through the cutting mechanism, greatly improving the grinding efficiency of the grinding mechanism. The problem of the long forage grass fibers being difficult to grind to a suitable size is solved, thereby significantly improving the granulation quality. The blade is serrated, greatly enhancing the cutting ability. Compared with ordinary flat blades, the serrated design increases the contact points and shearing force between the blade and the forage grass. At the same speed, the long-fiber forage grass can be cut off more quickly and effectively, greatly improving the cutting efficiency. This not only shortens the length of individual forage grass fibers, but also makes the cut grass segments more uniform, providing better raw materials for the subsequent grinding process and further improving the quality and efficiency of the overall feed granulation.

[0019] The present application improves the continuity of feeding through continuous conveying, reduces the downtime caused by blockage, and makes the entire feed processing process more efficient and stable.

[0020] The application can drive the rotating rod of the cutting mechanism and the rotating shaft of the crushing mechanism simultaneously through a first motor, thereby reducing the use of additional driving motors and lowering the cost of the equipment and energy consumption. Meanwhile, the coordination of the cutting and crushing processes in speed is ensured, and the stability and efficiency of the entire feed processing process are improved.

[0021] The high-speed impact of the hammers on the grass produces strong friction between the hammers and the toothed plate. The grass segments are repeatedly impacted and rubbed between the hammers and the toothed plate and are gradually crushed into fine particles. The toothed plate increases the collision and friction area of the grass during the crushing process, so that the grass not only interacts with the hammers but also fully rubs with the toothed plate under the impact of the hammers, further refining the particles.

[0022] The application realizes gentle grinding of the pollen through the cooperation of the movable grinding disc and the fixed grinding disc and the driving of the second motor and the driving shaft. This special grinding method can refine the pollen particles to the appropriate particle size under the premise of ensuring that the nutritional components of the pollen are not lost, meeting the requirements of mixing with crushed grass and subsequent granulation. At the same time, the problem of nutritional loss or poor processing effect caused by different processing methods of pollen and grass in the same crushing mechanism is avoided, improving the nutritional balance and quality of the feed.

[0023] The continuous rotation of the screw propeller keeps the pollen moving slowly and stably in the feed hopper, avoiding the problem of blockage caused by the accumulation and caking of pollen due to its high viscosity. This ensures that the pollen can smoothly enter the crushing mechanism for crushing, improving the continuity and stability of the pollen processing, and thus ensuring the smooth progress of the entire feed granulation process.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Example 1: This example provides a pelleting device for feed production, such as... Figures 1-6 As shown, the pelletizing device includes a housing 1, a first feed hopper 2 disposed on one side of the housing 1, and a crushing mechanism 3 disposed inside the housing 1; it also includes a mixing system 4 connected to the crushing mechanism 3, a pelletizing system 5 connected to the mixing system 4, and a discharge pipe 6 fixedly inserted into the housing 1 and connected to the pelletizing system 5.

[0034] In order to facilitate the crushing of the forage: the first feeding hopper 2 and the crushing mechanism 3 are provided with a cutting mechanism 7 for cutting the forage, the cutting mechanism 7 includes a rotating shaft 71 rotatably inserted into the first feeding hopper 2, a plurality of knife holders 72 arranged in a ring shape and fixed on the rotating shaft 71, blades 73 fixedly installed on the knife holders 72, a reinforcing plate 74 fixedly installed in the first feeding hopper 2 and matched with the blades 73, and a first motor 75 for driving the rotating shaft 71 to rotate. In order to improve the cutting efficiency of the forage: the blades 73 are serrated. The serrated blades 73 greatly enhance the cutting ability. Compared with ordinary flat blades 73, the serrated design increases the contact points and shear force of the blades 73 and the forage. At the same speed, long-fiber forage can be cut off more quickly and effectively, greatly improving the cutting efficiency. This not only shortens the length of individual forage fibers, but also makes the cut grass segments more uniform, providing better raw materials for the subsequent crushing process, and further improving the overall feed pellet quality and efficiency. When the first motor 75 drives the rotating shaft 71 to rotate at high speed, the knife holders 72 and blades 73 fixed on the rotating shaft 71 also rotate at high speed. The serrated blades 73 cut into the forage fibers during rotation with their sharp serrated edges. Due to the special shape of the serrations, each serration can act like a small pair of scissors, shearing the forage fibers. The combination of strong centrifugal force generated by rotation and the sharpness of the serrations allows long-fiber forage to be quickly cut into shorter segments in an instant. This efficient cutting method effectively shortens the length of forage fibers, laying a good foundation for the subsequent crushing process.

[0035] In order to prevent the raw materials from being blocked inside the first feeding hopper 2: the bottom of the first feeding hopper 2 is provided with a conveying belt 21, the conveying belt 21 is in the same horizontal plane as the reinforcing plate 74, and the shaft of the conveying belt 21 is connected to the rotating shaft 71 through a synchronizer 36. Through continuous conveying, the flowability of the material is maintained, ensuring that the forage can enter the cutting mechanism 7 stably and smoothly. This not only improves the continuity of feeding and reduces downtime caused by blockage, but also makes the entire feed processing process more efficient and stable. At the same time, the conveying belt 21 and the reinforcing plate 74 are in the same horizontal plane, ensuring the stability of the forage during conveying and further improving the cutting effect. The shaft of the conveying belt 21 is connected to the rotating shaft 71 through the synchronizer 36, and when the rotating shaft 71 rotates under the drive of the first motor 75, the shaft of the conveying belt 21 is driven to rotate synchronously through the synchronizer 36, so that the conveying belt 21 starts to operate. The forage falls from above the first feeding hopper 2 and accumulates on the conveying belt 21. As the conveying belt 21 operates, the forage is stably conveyed forward and moves towards the cutting mechanism 7. During the conveying process, the forage does not stay in the hopper for too long, effectively preventing the material from being blocked inside the first feeding hopper 2 and speeding up the movement of the material.

[0036] In order to improve the conveying efficiency: the surface of the conveying belt 21 is also provided with anti-skid protrusions 211. The anti-skid protrusions 211 make the grass more stable during conveying, and are not prone to sliding or deviation, ensuring that the grass can be accurately and smoothly conveyed into the cutting and crushing mechanism 3. Thus, the conveying efficiency is improved, and problems such as insufficient cutting or uneven feeding caused by unstable grass conveying are reduced, further ensuring the efficiency and stability of the entire feed granulation process. When the conveying belt 21 operates to move the grass, the anti-skid protrusions 211 are in close contact with the surface of the grass. The shape and material of the protrusions increase the friction between the grass and the belt, allowing the grass to better follow the movement direction of the belt. Even if bumps or tilting occur during conveying, the anti-skid protrusions 211 can tightly grasp the grass to prevent it from sliding, thus stably conveying the grass into the cutting and crushing mechanism 3, providing a stable material supply for the subsequent cutting and crushing processes.

[0037] The pulverizing mechanism 3 comprises a pulverizing box 31 fixedly arranged in the interior of the machine box 1 and communicated with the first feeding hopper 2, a rotating shaft 32 rotatably inserted into the pulverizing box 31, a plurality of supports 33 arranged at equal intervals on the rotating shaft 32, and hammer blades 34 fixedly installed on the supports 33. A filter screen 35 is arranged at the bottom of the pulverizing box 31 corresponding to the lower part of the hammer blades 34. The pulverizing box 31 is communicated with the mixing system 4 through a pipeline. The rotating shaft 32 is provided with a synchronizing part 36 connected with the rotating rod 71. In order to further improve the pulverizing effect on the forage grass, a plurality of toothed plates 311 are fixedly connected on the inner wall of the pulverizing box 31 at equal intervals. The hammer blades 34 cooperate with the fixed toothed plates 311 during high-speed rotation to further pulverize the forage grass. The pulverizing mechanism 3 realizes high-efficiency pulverization of the forage grass through the high-speed rotating hammer blades 34 and the cooperating filter screen 35 and toothed plates 311. After the forage grass is cut by the cutting mechanism 7 and enters the pulverizing box 31, the high-speed impact of the hammer blades 34 and the friction with the toothed plates 311 can rapidly pulverize the forage grass into fine particles. The setting of the filter screen 35 ensures that the pulverized particles meet certain particle size requirements. The oversized particles will be intercepted for further pulverization, thereby improving the pulverization quality. Meanwhile, the rotating rod 71 is connected with the rotating shaft 32 through the synchronizing part 36, which reduces the use of driving parts, reduces energy consumption and equipment cost, and improves the operation efficiency and economy of the entire device. The toothed plates 311 increase the collision and friction area of the forage grass during the pulverization process, so that the forage grass not only acts on the hammer blades 34 but also fully rubs against the toothed plates 311 under the impact of the hammer blades 34, thereby further refining the particles. This design makes the pulverized forage grass particles more uniform and fine, improves the quality and digestion and absorption rate of the feed, and is conducive to the feeding and health of animals. When the forage grass is cut by the cutting mechanism 7 and falls into the interior of the pulverizing box 31, the rotating shaft 32 rotates at high speed under the driving of the synchronizing part 36. The supports 33 and hammer blades 34 fixedly arranged on the rotating shaft 32 rotate at high speed. The hammer blades 34 impact the forage grass entering the pulverizing box 31 at high speed to swing the forage grass entering the pulverizing box 31. Meanwhile, the toothed plates 311 fixedly connected on the inner wall of the pulverizing box 31 at equal intervals cooperate with the hammer blades 34. The forage grass repeatedly collides and rubs between the hammer blades 34 and the toothed plates 311 and is gradually pulverized into fine particles. The pulverized particles are screened through the filter screen 35. The particles meeting the particle size requirements pass through the pipeline into the mixing system 4, and the oversized particles remain in the pulverizing box 31 for further pulverization by the hammer blades 34.

[0038] The synchronizer 36 comprises two synchronizer gears 361 fixedly sleeved on the rotating rod 71 and the rotating shaft 32 respectively, and a synchronizer tooth belt 362 sleeved on the two synchronizer gears 361. The synchronizer 36 comprises the synchronizer gears 361 fixedly sleeved on the rotating rod 71 and the rotating shaft 32 respectively and the synchronizer tooth belt 362 sleeved on the two synchronizer gears 361, which realizes the synchronous rotation of the rotating rod 71 and the rotating shaft 32. The rotating rod 71 of the cutting mechanism 7 and the rotating shaft 32 of the crushing mechanism 3 can be simultaneously driven by a first motor 75, which reduces the use of additional driving motors, lowers the equipment cost and energy consumption, and ensures the coordination of the cutting and crushing processes in speed, thereby improving the stability and efficiency of the entire feed processing process. When the first motor 75 drives the rotating rod 71 to rotate, the synchronizer gear 361 fixed on the rotating rod 71 rotates. Since the synchronizer tooth belt 362 is simultaneously sleeved on the two synchronizer gears 361, the rotation of the synchronizer gear 361 is transmitted to the other synchronizer gear 361 fixed on the rotating shaft 32 through the synchronizer tooth belt 362, thereby driving the rotating shaft 32 to rotate synchronously. In this way, the cutting mechanism 7 and the crushing mechanism 3 work cooperatively under the same power source, realizing an efficient process of cutting and crushing of the forage grass.

[0039] In order to facilitate the installation of the first motor 75, a motor bracket 751 is fixedly arranged on the machine box 1, the first motor 75 is fixedly installed on the motor bracket 751 through bolts, and the output end of the first motor 75 is fixedly connected with the end of the rotating shaft 32. The motor bracket 751 fixedly arranged on the crushing box 31 facilitates the installation of the first motor 75. The first motor 75 is fixed on the motor bracket 751 through bolts, which not only ensures firm installation but also facilitates the disassembly, maintenance or replacement of the first motor 75 when necessary. When installing the first motor 75, the motor bracket 751 is fixed on the crushing box 31 at a suitable position in advance. Then, the first motor 75 is placed on the motor bracket 751, the bolts are passed through the corresponding installation holes of the motor bracket 751 and the first motor 75, and the bolts are tightened to complete the installation. When the first motor 75 needs to be repaired or replaced due to failure, the first motor 75 can be removed from the motor bracket 751 by unscrewing the bolts, and the corresponding repair or replacement operation can be performed, which is simple and convenient.

[0040] The second embodiment is different from the first embodiment. Because the pollen is sticky and easy to adhere to the inside of the equipment, affecting the processing efficiency. Therefore, because of its high viscosity and easy to damage the nutritional ingredients, in order to facilitate the separate crushing of the pollen, the crushing mechanism 8 for separate crushing of the pollen is arranged in the machine box 1. The crushing mechanism 8 includes a second feeding hopper 81 fixedly inserted on the other side of the machine box 1, a crushing box 82 fixedly arranged in the machine box 1 and communicating with the second feeding hopper 81, a movable grinding disc 83 rotatably arranged at the bottom of the crushing box 82, a fixed grinding disc 84 fixedly arranged in the crushing box 82 for adapting to the movable grinding disc 83, and a conical tube 85 fixedly inserted on the fixed grinding disc 84 for guiding the pollen into the fixed grinding disc 84 and the movable grinding disc 83. The conical tube 85 is inserted in the fixed grinding disc 84 and fixedly connected with the driving shaft 86. The top of the driving shaft 86 penetrates the top wall of the crushing box 82 and the machine box 1. A second motor 87 is fixedly installed on the machine box 1, and the output end of the second motor 87 is fixedly connected with the end of the driving shaft 86. The crushing mechanism 8 arranged in the machine box 1 is specially used for separate crushing of the pollen. Through the cooperation of the movable grinding disc 83 and the fixed grinding disc 84, and the driving of the second motor 87 and the driving shaft 86, the pollen is gently ground. This special grinding method can refine the pollen particles to the appropriate particle size under the premise of ensuring that the nutritional ingredients of the pollen are not lost, meet the requirements of mixing with crushed grass and subsequent granulation. At the same time, it avoids the problem of nutritional loss or poor processing effect caused by different processing methods of pollen and grass in the same crushing mechanism 3, improves the nutritional balance and quality of the feed. The pollen enters the crushing box 82 from the second feeding hopper 81 and is guided into the fixed grinding disc 84 and the movable grinding disc 83 through the conical tube 85. The output end of the second motor 87 is fixedly connected with the end of the driving shaft 86. When the second motor 87 is started, the driving shaft 86 drives the movable grinding disc 83 to rotate at high speed. The movable grinding disc 83 and the fixed grinding disc 84 cooperate with each other to gently grind the pollen between them. During the grinding process, the pollen is squeezed and rubbed between the two grinding discs and is gradually ground to the appropriate particle size. The ground pollen is horizontally conveyed to the upper feeding port of the mixing system 4 through the pipeline to realize accurate mixing with the crushed grass.

[0041] In order to prevent the pollen from being blocked in the second feeding hopper 81: the bottom of the second feeding hopper 81 is rotatably plugged with a spiral propeller 811, the outside of the second feeding hopper 81 is fixedly installed with a third motor 812, and the output end of the third motor 812 is fixedly connected with the shaft of the spiral propeller 811. The spiral propeller 811 rotatably plugged in the bottom of the second feeding hopper 81 effectively prevents the pollen from being blocked in the second feeding hopper 81 under the driving of the third motor 812. The continuous rotation of the spiral propeller 811 enables the pollen to slowly and stably move in the feeding hopper, avoiding the blocking problem caused by the accumulation and caking of the pollen due to the relatively large viscosity. This ensures that the pollen can smoothly enter the crushing mechanism 8 for crushing, improves the continuity and stability of the pollen processing, and further ensures the smooth progress of the entire feed granulation process. When the third motor 812 is started, the output end drives the shaft of the spiral propeller 811 to rotate. The spiral propeller 811 rotates at the bottom of the second feeding hopper 81, slowly pushes the pollen accumulated at the bottom of the feeding hopper along the direction of the spiral blade. Under the action of the spiral propeller 811, the pollen constantly moves towards the direction of the crushing box 82 and does not stay in the second feeding hopper 81 for too long, thereby preventing the pollen from being blocked in the second feeding hopper 81 and ensuring that the pollen can smoothly enter the crushing mechanism 8 for subsequent crushing processing.

[0042] Among them, the mixing system 4 and the granulation system 5 adopt the original technology;

[0043] The mixing system is located below the crushing mechanism 3 and is composed of a stirring cylinder and a stirring device. The stirring cylinder has a spiral structure inside, which can increase the movement path of the material during stirring and improve the mixing effect. The stirring device adopts double-shaft stirring paddles, and the paddles are designed in a special "S" shape, which can fully mix the pollen and the crushed forage during stirring, ensuring uniform distribution of nutrients.

[0044] The uniformly mixed material enters the granulation system 5 from the bottom of the stirring cylinder. The granulation system 5 adopts a flat die granulator, and multiple circular die holes are uniformly distributed on the flat die. The material is extruded through the die holes to form cylindrical particles under the extrusion of the roller. At the same time, a cutter device is arranged below the flat die, and the cutter can cut the extruded cylindrical particles into appropriate size of pellet feed according to the set length.

[0045] The wiring diagram of the first motor 75, the second motor 87 and the third motor 812 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control mode and wiring arrangement of the first motor 75, the second motor 87 and the third motor 812 are not explained in detail.
