Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a liquid fermentation biological feed production device and method. Background Art

[0002] Feed processing usually refers to the processing of raw materials such as grains, beans, hay and straw into products for animal use through a series of processes. In order to facilitate animal digestion and absorption, the feed often needs to go through steps such as drying, crushing, mixing and fermentation during the production process. Therefore, a conveying device is usually required to transport the feed between each step. The existing conveying devices can be mainly divided into two types: belt conveyors and screw conveyors. Among them, screw conveyors, also known as auger conveyors, are widely used due to their simple structure and flexible use. When in use, the material can be pushed by the rotating spiral blades to achieve material transportation and lifting.

[0003] The patent document with authorization announcement number CN113844683B discloses a new type of grain conveying equipment, including a load-bearing bracket, on which is provided a shaking feeding mechanism for synchronous dust removal during grain conveying, the shaking feeding mechanism including an outer cylinder fixed on the load-bearing bracket, and a shaking net cylinder is provided inside the outer cylinder, a feeding auger mechanism is provided inside the shaking net cylinder, the outer cylinder is provided with a movable driving mechanism for driving the feeding auger mechanism to work and cooperate with the shaking net cylinder for real-time shaking feeding, and a conveniently disassembled sealing and plugging mechanism is provided at the bottom of the outer cylinder for conveniently filtering out dust and real-time cleaning. During the continuous conveying of grain, this patent can effectively shake and filter out dust mixed in the grain through shaking conveying and lifting, thereby effectively improving the quality of the grain.

[0004] However, when the above-mentioned conveying equipment is used to convey the crushed wheat bran or straw fragments, since these feeds have a small density and a large surface area, they are easily entangled with each other and accumulate in the feed hopper to cause blockage, making it impossible for the feed to flow smoothly. In addition, there may be some incompletely crushed feed in the feed. If it is not screened out in time, it may affect the production quality of the feed. Summary of the invention

[0005] The present invention provides a liquid fermentation biological feed production device and method, aiming to solve the problem that when the conveying equipment in the related art conveys the crushed wheat bran or straw fragments, the feed is easily accumulated in the feed hopper to cause blockage, so that the feed cannot flow smoothly. In addition, there may be some incompletely crushed feed in the feed, which may affect the quality of feed production if it is not screened out in time.

[0006] In a first aspect, a liquid fermented biological feed production device of the present invention comprises a frame, a conveying cylinder and a conveying assembly, wherein a feed hopper and a discharge hopper are respectively provided at both ends of the conveying cylinder, and further comprises a screening mechanism and a material discharging auxiliary mechanism provided in the feed hopper;

[0007] The screening mechanism includes two rollers and a driving assembly 1. The two rollers are symmetrically arranged, and there is a space for feed to fall between the two rollers. The driving assembly 1 is used to drive the two rollers to rotate in opposite directions. Each roller is provided with a plurality of hooking units along its circumference. Each hooking unit includes a plurality of hooking rods and a driving structure. The plurality of hooking rods are arranged in an axial array along the roller, and there is a gap between two adjacent hooking rods for small feed to pass through. Each hooking rod is arranged along the radial direction of the roller, and the end portion penetrates the side wall of the roller and extends outward. The driving structure is used to drive the plurality of hooking rods in the same hooking unit to move synchronously along the radial direction of the roller.

[0008] The material unloading auxiliary mechanism includes two flip plates and a driving component 2. The two flip plates are correspondingly arranged above the two rollers. The ends of the two flip plates that are away from each other are respectively hinged to the feed hopper. The driving component 2 is used to drive the flip plates to swing around their respective hinged ends.

[0009] The hook unit can be used to comb the falling feed and intercept the large feed, thereby improving the production quality of subsequent feed. At the same time, the swing of the flip plate can break up the feed accumulation in the feed hopper to ensure the feed transportation efficiency.

[0010] Preferably, each drum is provided with a plurality of installation cavities for installing hook feed units, and the end of the installation cavity away from the drum axis passes through the side wall of the drum, and collecting cavities are respectively provided on both sides of the feed hopper, and the collecting cavities are communicated with the interior of the feed hopper for collecting the screened large feed, and when the end of the hook rod faces the other drum, the hook rod extends outward, and the ends of the hook rods on the two drums can contact each other, when the end of the hook rod faces the corresponding flip plate, the hook rod contracts inward, and when the end of the hook rod faces the collecting cavity on the corresponding side, the hook rod extends outward, and the end of each hook rod extending outward is connected to an extrusion plate, and the diameter of the extrusion plate is larger than the diameter of the hook rod.

[0011] After the falling feed is combed by the hook unit, the large feed can be intercepted on the hook rod. At this time, the driving structure drives the hook rod to retract inward, so that the large feed can be gathered between the extrusion plate and the side wall of the drum, which is conducive to the subsequent separation of the large feed from the hook rod.

[0014] Preferably, drive component 2 includes a contact block arranged at the lower end of the flip plate, the contact block is inclined on the side facing the roller, and the inclined surface gradually inclines toward the direction close to the roller along the rotation direction of the roller. When the rod is in groove 2, the end of the hook rod can contact the inclined surface on the contact block.

[0015] The hook rod and the contact block cooperate to make the flip plate swing up and down to break up the feed accumulation in the feed hopper and ensure that the feed can flow smoothly.

[0016] Preferably, a plurality of protrusions are arranged at intervals in groove one, and a side of each protrusion away from the side wall of the feed hopper is in the shape of an inclined surface, and the inclined surface gradually inclines toward the direction away from the side wall of the feed hopper along the rotation direction of the drum. During the sliding process of the rod in groove one, the rod can contact the inclined surface on the protrusion, so that the slide bar moves along the axial direction of the roller, and a spring 2 is provided between the end of the slide bar away from the guide groove and the side wall of the feed hopper for driving the slide bar to reset.

[0017] The rod and the protrusion cooperate to make the hook unit vibrate back and forth along the axial direction of the drum, so that the feed falling on the hook rod shakes, which is conducive to the small feed mixed in this part of the feed falling from between two adjacent hook rods, thereby improving the screening effect of the feed.

[0018] Preferably, a drive plate is provided in the installation cavity, the drive plate slides with the roller in the axial direction of the roller and is relatively fixed to the roller in the radial direction of the roller, the hook rod passes through the drive plate and cooperates with the drive plate thread, and the hook rod is rotatably connected to the slide rod at the end thereof.

[0019] The hook rod can be rotated around its own axis through the threaded cooperation between the hook rod and the driving plate, which is conducive to breaking up the accumulation of feed above the hook rod, making it easier for small feed stuck between the two hook rods to fall off, and avoiding small feed being blocked between the two hook rods and affecting the screening effect of the feed.

[0020] Preferably, the conveying assembly includes an auger shaft, auger blades and a drive motor. The auger shaft is arranged in the conveying cylinder and rotates along the length direction of the conveying cylinder. The auger blades are installed on the outside of the auger shaft.

At the same time, under the action of the driving structure, multiple hook rods in the same group of hooking units are driven to move synchronously along the radial direction of the roller.

At the same time, the swing of the flip plate can break up the feed accumulation in the feed hopper, so that the feed can flow smoothly and ensure the feed transportation efficiency.

[0028] The beneficial effects of the present invention are:

[0029] 1. The present invention is provided with a screening mechanism. After adding feed into the feed hopper, the driving component 1 can drive the two rollers to rotate in opposite directions, and drive the hook unit to rotate synchronously.

[0030] 2. The present invention is provided with a feeding auxiliary mechanism, which can drive the flip plate to swing through the driving component 2, break up the feed accumulation in the feed hopper, prevent the feed from being blocked in the feed hopper or forming an "arch bridge" phenomenon, so that the feed can flow smoothly and ensure the feed transportation efficiency.

[0031] 3.

[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figures 1 to 7 As shown, a liquid fermentation biological feed production device of the present invention includes a frame 1, a conveying cylinder 11, a conveying component, a screening mechanism and a feeding auxiliary mechanism.

[0044] The conveying cylinder 11 is tiltedly arranged on the frame 1, and a feed hopper 12 is provided at one end of the conveying cylinder 11 on the lower side, and a discharge hopper 13 is provided at the other end. The conveying component is arranged in the conveying cylinder 11, and is used to convey the feed and move it along the length direction of the conveying cylinder 11, so that the feed can be discharged outward from the discharge hopper 13. The screening mechanism is arranged in the feed hopper 12, and is used to screen the feed to be conveyed, so as to screen out the large feed that does not meet the requirements and improve the quality of the subsequent feed. The feeding auxiliary mechanism is arranged in the feed hopper 12, and is used to assist the feed to smoothly enter the inside of the conveying cylinder 11 from the feed hopper 12, so as to avoid the feed from accumulating in the feed hopper 12 and affecting the conveying efficiency.

[0045] The screening mechanism includes two rollers 2 and a driving component 1. The two rollers 2 are symmetrically arranged with a space for feed to fall between them. The driving component 1 is used to drive the two rollers 2 to rotate in opposite directions. Each roller 2 is provided with a plurality of hooking units 21. The plurality of hooking units 21 are arranged at intervals along the circumference of the roller 2. Each hooking unit 21 includes a plurality of hook rods 211 and a driving structure. The plurality of hook rods 211 are arranged in an axial array along the roller 2, and there is a gap between two adjacent hook rods 211 for small feed to pass through. Each hook rod 211 is arranged along the radial direction of the roller 2, and the end portion penetrates the side wall of the roller 2 and extends outward. The driving structure is used to drive the plurality of hook rods 211 in the same hooking unit 21 to move synchronously along the radial direction of the roller 2.

[0046] Specifically, Figures 2 to 7As shown, the driving component 1 drives the two rollers 2 to rotate in opposite directions, and drives the hook unit 21 arranged on the roller 2 to rotate synchronously. Then, after the feed is added to the feed hopper 12, the feed will fall from between the two rollers 2. In this process, the driving structure drives multiple hook rods 211 in the same hook unit 21 to move synchronously along the radial direction of the roller 2. When the hook rod 211 remains in a state of extending outward, the fallen feed can be combed by the hook rods 211 arranged at intervals. When the hook rod 211 passes through the feed, the small feed therein will pass between two adjacent hook rods 211 and continue to fall, while the large feed therein will be intercepted on the hook rod 211. As the roller 2 continues to rotate, the large feed intercepted on the hook rod 211 will rotate synchronously with the hook rod 211, so as to separate the large feed from the rest of the feed, thereby realizing the screening of the large feed, which is beneficial to ensuring the production quality of the feed.

[0047] The material unloading auxiliary mechanism includes two flip plates 3 and a driving component 2. The two flip plates 3 are correspondingly arranged above the two rollers 2. The ends of the two flip plates 3 that are away from each other are respectively hinged to the feed hopper 12. The driving component 2 is used to drive the flip plates 3 to swing around their respective hinged ends.

[0048] Specifically, Figures 1 to 5 As shown, after the feed is added to the feed hopper 12, the feed will fall from between the two flip plates 3. Since these feeds have a smaller density and a larger surface area, they are easily entangled with each other and piled up in the feed hopper 12, making it impossible for the feed to flow smoothly. At this time, the flip plates 3 can be driven by the driving component 2 to swing around their respective hinged ends to break up the accumulation of the feed, prevent the feed from being blocked in the feed hopper 12 or forming an "arch bridge" phenomenon, so that the feed can flow smoothly into the conveying cylinder 11, thereby ensuring the conveying efficiency of the feed.

[0049] In some embodiments, each drum 2 is provided with a plurality of installation cavities 201 for installing the hook unit 21, and the end of the installation cavity 201 away from the axis of the drum 2 passes through the side wall of the drum 2, and a collecting cavity 14 is provided on both sides of the feed hopper 12, and the collecting cavity 14 is communicated with the interior of the feed hopper 12, which is used to collect the screened large feed. When the end of the hook rod 211 faces the other drum 2, the hook rod 211 extends outward, and the ends of the hook rods 211 on the two drums 2 can contact each other to intercept the large feed. When the end of the hook rod 211 faces the corresponding flip plate 3, the hook rod 211 contracts inward, and when the end of the hook rod 211 faces the collecting cavity 14 on the corresponding side, the hook rod 211 extends outward. The end of each hook rod 211 extending outward is connected to an extrusion plate 212, and the diameter of the extrusion plate 212 is larger than the diameter of the hook rod 211.

[0050] Specifically, Figures 3 to 7As shown, the two rollers 2 are driven to rotate in opposite directions by the driving component 1, and the hook unit 21 arranged on the roller 2 is driven to rotate synchronously. When the end of the hook rod 211 faces the other roller 2, the multiple hook rods 211 in the hook unit 21 are driven by the driving structure to move synchronously along the radial direction of the roller 2, so that the hook rod 211 extends outward. At this time, the ends of the hook rods 211 on the two rollers 2 can contact each other, so that the fallen feed can be screened by the hook rod 211, and the large feed is intercepted above the hook rod 211 to avoid the phenomenon that some feed falls directly from the middle, thereby ensuring the screening effect. The roller 2 continues to rotate, and when the end of the hook rod 211 faces the corresponding flip plate 3, the multiple hook rods 211 in the hook unit 21 are driven by the driving structure. 11 moves synchronously along the radial direction of the drum 2, so that the hook rod 211 shrinks inward, and drives the squeezing plate 212 connected to the hook rod 211 to move synchronously, so as to squeeze the large feed intercepted on the hook rod 211 between the squeezing plate 212 and the side wall of the drum 2, and the large feed is concentrated and gathered, which is conducive to the subsequent separation of the large feed from the hook rod 211. The drum 2 continues to rotate. When the end of the hook rod 211 faces the collecting chamber 14, the driving structure drives the multiple hook rods 211 in the hook unit 21 to move synchronously along the radial direction of the drum 2, so that the hook rod 211 extends outward, and the squeezing plate 212 releases the clamping of the large feed. At this time, the large feed will directly fall into the collecting chamber 14 for collection, thereby realizing the effective separation of large and small feeds, which is conducive to improving the production quality of feed.

[0051] In some embodiments, the conveying assembly includes an auger shaft 15, an auger blade 16 and a drive motor 17. The auger shaft 15 is arranged in the conveying cylinder 11 to rotate along the length direction of the conveying cylinder 11, and the auger blade 16 is installed on the outside of the auger shaft 15. The drive motor 17 is arranged on the conveying cylinder 11 to drive the auger shaft 15 to rotate. Specifically, Figure 1 and Figure 2 As shown, starting the drive motor 17 can drive the auger shaft 15 to rotate, and drive the auger blades 16 to rotate synchronously, so as to transport and lift the feed along the length direction of the conveying cylinder 11.

[0052] In some embodiments, drive assembly 1 includes gear 1 41, gear 2 42, pulley 1 43, pulley 2 44 and a transmission belt 45. Gear 1 41 and pulley 1 43 are both installed on the outside of the auger shaft 15. Gear 2 42 is fixedly connected to the end of one of the rollers 2, and gear 1 41 is meshingly connected to gear 2 42. Pulley 2 44 is fixedly connected to the end of the other roller 2, and the transmission belt 45 is sleeved on the outside of pulley 1 43 and pulley 2 44.

[0053] Specifically, Figure 1 and Figure 2As shown, starting the drive motor 17 drives the auger shaft 15 to rotate, and can drive the gear 1 41 and the pulley 1 43 to rotate. When the gear 1 41 rotates, it can drive the gear 2 42 to rotate through the meshing transmission between the gear 1 41 and the gear 2 42, and at the same time drive the roller 2 connected to the gear 2 42 to rotate, and the rotation direction of the roller 2 is opposite to that of the gear 1 41. When the pulley 1 43 rotates, it can drive the pulley 2 44 to rotate under the action of the transmission belt 45, and at the same time drive the roller 2 connected to the pulley 2 44 to rotate, and the rotation direction of the roller 2 is consistent with that of the pulley 1 43, that is, the rotation directions of the two rollers 2 are opposite.

[0054] In some embodiments, the driving structure includes a guide groove 121 provided on the side wall of the feed hopper 12, and a slide bar 213 slidably provided in the installation cavity 201, and a rod 214 is provided at the end of the slide bar 213, so that the slide bar 213 slides with the guide groove 121 through the rod 214, and a spring 215 for driving the slide bar 213 to reset is connected between the slide bar 213 and the drum 2, and multiple hook rods 211 in the same group of hook units 21 are provided on the same slide bar 213. In this embodiment, the guide groove 121 includes a groove 1 1211, a groove 2 1211, and a groove 3 1211 arranged in sequence along the rotation direction of the drum 2. 2 and slot three 1213, the distance between slot one 1211 and the axis of the roller 2 is consistent with the distance between slot three 1213 and the axis of the roller 2, the distance between slot two 1212 and the axis of the roller 2 is smaller than the distance between slot one 1211 and the axis of the roller 2, when the rod 214 is in slot one 1211, the end of the hook rod 211 faces the other roller 2, when the rod 214 is in slot two 1212, the end of the hook rod 211 faces the bottom of the corresponding flip plate 3, and when the rod 214 is in slot three 1213, the end of the hook rod 211 faces the connection between the collecting chamber 14 and the feeding hopper 12.

[0055] Specifically, Figures 2 to 7As shown, when the rod 214 is in the first groove 1211, the end of the hook rod 211 faces the other roller 2. At this time, the hook rod 211 extends outward, and the ends of the hook rods 211 on the two rollers 2 can contact each other, combing the falling feed and intercepting the large feed therein, so that the large feed falls on the hook rod 211. As the roller 2 continues to rotate, when the rod 214 is in the second groove 1212, the hook rod 211 contracts inward. Through the contraction of the hook rod 211, the large feed falling on the hook rod 211 can be pushed to gradually gather, and the large feed is clamped between the extrusion plate 212 and the side wall of the roller 2. The hook rod 211 is arranged between the two grooves 1213 and 1214, which is conducive to the subsequent large feed falling off from the hook rod 211. As the drum 2 continues to rotate, when the rod 214 is in the groove 1213, the end of the hook rod 211 faces the connection between the collecting chamber 14 and the feed hopper 12. At this time, the hook rod 211 extends outward, so that the large feed clamped between the squeezing plate 212 and the side wall of the drum 2 falls directly into the collecting chamber 14, and the large feed is collected for subsequent processing. As the drum 2 continues to rotate, when the rod 214 is in the groove 1211, the hook rod 211 combs the feed again and intercepts the large feed therein.

[0056] In some embodiments, the guide groove 121 further includes a groove 1214, which is disposed between the groove 1213 and the groove 1211, and the distance between the groove 1214 and the axis of the drum 2 is smaller than the distance between the groove 1211 and the axis of the drum 2. Specifically, Figures 2 to 5 As shown, when the rod 214 is in the slot three 1213, the hook rod 211 extends outward to send the intercepted large feed to the collecting chamber 14 for collection. As the drum 2 continues to rotate, when the rod 214 is in the slot four 1214, the end of the hook rod 211 will face the side wall of the feed hopper 12. At this time, the hook rod 211 contracts inward to avoid the hook rod 211 from colliding with the side wall of the feed hopper 12 and affecting the rotation of the drum 2. As the drum 2 continues to rotate, when the rod 214 is in the slot one 1211, the hook rod 211 will extend again to comb the feed and intercept the large feed therein.

[0057] Among them, in order to ensure the smooth sliding of the rod 214 in the guide groove 121, an inclined groove 1 is connected between the outlet end of groove 1211 and the inlet end of groove 2 1212, and the inclined groove 1 is gradually inclined toward the direction close to the axis of the drum 2 along the rotation direction of the drum 2, an inclined groove 2 is connected between the outlet end of groove 2 1212 and the inlet end of groove 3 1213, and the inclined groove 2 is gradually inclined toward the direction away from the axis of the drum 2 along the rotation direction of the drum 2, an inclined groove 3 is connected between the outlet end of groove 3 1213 and the inlet end of groove 4 1214, and the inclined groove 3 is gradually inclined toward the direction close to the axis of the drum 2 along the rotation direction of the drum 2, an inclined groove 4 is connected between the outlet end of groove 4 1214 and the inlet end of groove 1 1211, and the inclined groove 4 is gradually inclined toward the direction away from the axis of the drum 2 along the rotation direction of the drum 2.

[0058] In some embodiments, a plurality of protrusions 22 are arranged at intervals in the groove 1211, and the side of each protrusion 22 away from the side wall of the feed hopper 12 is in the shape of an inclined surface, and the inclined surface gradually inclines toward the direction away from the side wall of the feed hopper 12 along the rotation direction of the drum 2. During the sliding of the rod 214 in the groove 1211, the rod 214 can contact the inclined surface on the protrusion 22, so that the slide bar 213 moves along the axial direction of the drum 2. A spring 216 for driving the slide bar 213 to reset is provided between the end of the slide bar 213 away from the guide groove 121 and the feed hopper 12. One end of the spring 216 is connected to the slide bar 213, and the other end abuts against the side wall of the feed hopper 12.

[0059] Specifically, Figures 2 to 7 As shown, when the rod 214 slides in the groove 1211, the rod 214 contacts with the plurality of protrusions 22 in sequence. At this time, under the action of the inclined surface on the protrusion 22, the rod 214 moves along the axial direction of the drum 2 in a direction away from the guide groove 121, and at the same time drives the slide bar 213 to move synchronously along the axial direction of the drum 2, and compresses the spring 216 to store force. When the rod 214 passes over the protrusion 22, the slide bar 213 quickly moves in the opposite direction under the action of the spring 216. The sliding rod 213 is moved and reset, and the sliding rod 213 is vibrated by the movement and reset, and the multiple hook rods 211 connected to the sliding rod 213 are driven to vibrate, and the rod 214 contacts the multiple protrusions 22 in the groove 1211 in sequence, so that the hook rod 211 vibrates back and forth, so that the feed falling on the hook rod 211 can be shaken, and the small feed mixed in this part of the feed can be smoothly dropped from between the two hook rods 211, thereby improving the screening effect of the feed.

[0060] In some embodiments, a drive plate 23 is provided in the installation cavity 201. The drive plate 23 slides with the roller 2 in the axial direction of the roller 2 and is relatively fixed to the roller 2 in the radial direction of the roller 2. The hook rod 211 passes through the drive plate 23 and is threadedly engaged with the drive plate 23. The hook rod 211 is rotatably connected to the slide rod 213 at the end thereof.

[0061] Specifically, Figures 2 to 7 As shown, through the sliding cooperation between the rod 214 and the guide groove 121, the slide rod 213 can be driven to move along the radial direction of the drum 2, and the hook rod 211 connected to the slide rod 213 can be driven to move synchronously. In this process, the hook rod 211 can be driven to rotate around its own axis through the threaded cooperation between the hook rod 211 and the driving plate 23. The rotating hook rod 211 can break up the accumulation of feed, promote the uniform distribution of feed on the hook rod 211, and further improve the screening effect of large feed. In addition, due to the rotation of the hook rod 211, the small feed stuck between the two hook rods 211 is easier to fall off, avoiding the small feed blocking the gap between the two adjacent hook rods 211, so as to ensure the screening effect of the feed.

[0062] In some embodiments, drive component 2 includes a contact block 31 disposed on the lower side of the flip plate 3, and the contact block 31 is inclined toward the side of the roller 2, and the inclined surface gradually inclines toward the direction close to the roller 2 along the rotation direction of the roller 2. When the rod 214 is in the groove 2 1212, the end of the hook rod 211 can contact the inclined surface on the contact block 31.

[0063] Specifically, Figures 2 to 5 As shown, when the roller 2 is driven to rotate by the driving component 1, the hook unit 21 arranged on the roller 2 will be driven to rotate synchronously, so that the rod 214 slides in the guide groove 121. When the rod 214 is in the groove 1212, the end of the hook rod 211 faces the corresponding flip plate 3 and can contact the contact block 31 at the lower end of the flip plate 3. At this time, under the action of the inclined surface on the contact block 31, the flip plate 3 can be pushed to flip upward around its respective hinged end. As the roller 2 continues to rotate, when the end of the hook rod 211 passes over the contact block 31, the flip plate 3 will flip downward under the action of its own gravity. Through the up and down swinging of the flip plate 3, the accumulation of feed in the feed hopper 12 can be broken up, ensuring that the feed can flow smoothly into the conveying cylinder 11.

[0064] like Figures 1 to 7 As shown, the present invention also provides a production method using the above liquid fermentation biological feed production device, which specifically includes the following steps:

[0065] S1, feeding: adding feed to be transported into the feed hopper 12;

[0066] S2, feeding: under the action of the driving component 2, the flip plate 3 is driven to swing, breaking up the feed accumulated in the feed hopper 12, so that the feed can fall smoothly into the conveying cylinder 11, avoiding the feed from accumulating in the feed hopper 12 and affecting the conveying efficiency;

[0067] S3, screening: the driving assembly 1 drives the two rollers 2 to rotate in opposite directions, and drives the hooking unit 21 arranged on the roller 2 to rotate synchronously. At the same time, under the action of the driving structure, multiple hook rods 211 in the same group of hooking units 21 are driven to move synchronously along the radial direction of the roller 2. In this process, the hook rods 211 can comb the falling feed, so that small feed falls from between two adjacent hook rods 211, and large feed is intercepted above the hook rods 211, so that the large feed can be screened out to ensure the production quality of subsequent feed;

[0068] S4, conveying: The feed falling into the conveying cylinder 11 is conveyed by the conveying assembly, so that the feed is discharged from the discharge hopper 13 for subsequent processing.

[0069] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
