[0002] Distillers' grains are a major byproduct of brewing, rich in crude protein, amino acids, and trace elements. After drying, they can be used as high-quality feed or organic fertilizer, possessing high resource utilization value.

[0015] Compared with the prior art, this application has the following technical effects: The device consists of a first crushing mechanism, a second crushing mechanism, and a screening mechanism integrated vertically along the material flow direction.

The two-stage crushing structure: the first crushing mechanism shears large pieces of distiller's grains into smaller pieces; the second crushing mechanism crushes and refines these smaller pieces through grinding and rubbing. This step-by-step processing from coarse to fine crushing ensures more uniform particle size in the output distiller's grains, providing favorable conditions for subsequent drying and other processes. In the second crushing mechanism, the first crushing roller moves in a circular motion with the horizontal plate, relying on friction with the material to achieve rotation and crush the bottom lees; at the same time, the second crushing roller rotates actively while revolving around the central plate; the combined motion of the two sets of crushing rollers effectively increases the area and frequency of action on the material, significantly improving crushing efficiency and fine crushing capability; the screening mechanism is equipped with a pair of first and second actuating plates that can be driven by the first and second connecting rods to reciprocate, and move back and forth on the screen plate through the actuating rods at the bottom of the two plates, continuously turning and dispersing the accumulated lees fragments, breaking the material bridging, and allowing qualified lees fragments to quickly pass through the screen holes; this design effectively avoids screen plate clogging and ensures the continuity of the screening process and the separation accuracy.

[0018] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] The following reference Figures 1 to 9 This application describes an integrated apparatus for crushing and screening distiller's grains according to some embodiments.

[0021] Example 1 An integrated device for crushing and screening distiller's grains includes a first crushing mechanism 2, a mounting plate 1, a second crushing mechanism 3, a mounting frame 4, and a screening mechanism 5. The first crushing mechanism 2 crushes large pieces of distiller's grains into smaller pieces. The mounting plate 1 is fixedly mounted on one side of the first crushing mechanism 2. The top of the second crushing mechanism 3 is connected to the mounting plate 1. The second crushing mechanism 3 communicates with the first crushing mechanism 2. The second crushing mechanism 3 crushes the small pieces of distiller's grains output from the first crushing mechanism 2 into smaller pieces. The mounting frame 4 is located at the bottom of the second crushing mechanism 3 and is fixedly connected to both sides of the second crushing mechanism 3. The screening mechanism 5 is mounted on the mounting frame 4 and is located below the second crushing mechanism 3. The screening mechanism 5 screens the smaller pieces of distiller's grains output from the second crushing mechanism 3.

[0022] According to an embodiment of the integrated device for crushing and screening distiller's grains, the first crushing mechanism 2, the second crushing mechanism 3, and the screening mechanism 5 are activated. Large pieces of distiller's grains are introduced into the first crushing mechanism 2. The first crushing mechanism 2 crushes the large pieces of distiller's grains into smaller pieces, which are then output to the second crushing mechanism 3 connected to it. The mounting plate 1 is used for installation in the second crushing mechanism 3. When the smaller pieces of distiller's grains enter the second crushing mechanism 3, the second crushing mechanism 3 further refines and crushes them to obtain fragmented distiller's grains. The obtained fragmented distiller's grains fall directly into the screening mechanism 5 for screening, thus finally obtaining the screened fragmented distiller's grains. The mounting frame 4 is used for the installation and support of the second crushing mechanism 3 and the screening mechanism 5. In this embodiment, the device only requires large pieces of distiller's grains to be placed into the first crushing mechanism 2, and then the first crushing mechanism 2, the second crushing mechanism 3, and the screening mechanism 5 operate simultaneously to directly obtain the final screened fragmented distiller's grains, realizing the integrated operation of crushing and screening.

[0023] As an optional implementation of this embodiment, the first crushing mechanism 2 further includes a crushing bucket 21, a first rotating shaft 22, a second rotating shaft 23, a first gear 24, a second gear 25, and a first motor 26; wherein, the bottom of the crushing bucket 21 is connected to the second crushing mechanism 3; both ends of the first rotating shaft 22 are rotatably connected to two opposing inner walls of the crushing bucket 21; one end of the first rotating shaft 22 penetrates through the inner wall of the crushing bucket 21 and extends to the outside of the crushing bucket 21; the first rotating shaft 22 is provided with uniformly arranged first crushing blades 221; both ends of the second rotating shaft 23 are rotatably connected to two opposing inner walls of the crushing bucket 21; both ends of the second rotating shaft 23 penetrate through each of the crushing bucket 21... The second rotating shaft 23 is located on the horizontal side of the first rotating shaft 22 and is arranged parallel to the first rotating shaft 22. The second rotating shaft 23 is provided with uniformly arranged second crushing blades 231, which are staggered with the first crushing blades 221. The first gear 24 is fixedly sleeved on the end of the first rotating shaft 22 located outside the crushing bucket 21. The second gear 25 is fixedly sleeved on the end of the second rotating shaft 23 near the first gear 24. The second gear 25 is meshed with the first gear 24. The first motor 26 is located on the outside of the crushing bucket 21. The output shaft of the first motor 24 is fixedly connected to the end of the second rotating shaft 23 away from the second gear 25.

[0024] It should be noted that the crushing bucket 21 is a hollow structure with openings at the top and bottom. The first rotating shaft 22 and the second rotating shaft 23 are horizontally spaced within the crushing bucket 21; the first rotating shaft 22 and the second rotating shaft 23 are at the same horizontal height. During operation, the first motor 26 rotates, driving the second rotating shaft 23 to rotate. A first gear 24 is fitted onto one end of the first rotating shaft 22 outside the crushing bucket 21, and a second gear 25 is fixedly fitted onto one end of the second rotating shaft 23 near the first gear 24, with the second gear 25 meshing with the first gear 24. Simultaneously, the first rotating shaft 22 is provided with evenly arranged first crushing blades 221, and the second rotating shaft 23 is provided with evenly arranged... The second crushing blade 231 is staggered with the first crushing blade 221. Therefore, when the second rotating shaft 23 rotates, the first rotating shaft 22 rotates in the opposite direction through the meshing first gear 24 and second gear 25. This allows the first crushing blade 221 on the first rotating shaft 22 and the second crushing blade 231 on the second rotating shaft 231 to rotate in opposite directions. This enables the first crushing blade 221 and the second crushing blade 231 to shear and crush the large pieces of lees that fall between them, resulting in smaller pieces of lees. Finally, the smaller pieces of lees enter the second crushing mechanism 3 through the opening at the bottom of the crushing hopper 21 for further crushing.

[0025] As an optional implementation of this embodiment, the second crushing mechanism 3 further includes a crushing cylinder 31, a driving assembly 32, and a crushing assembly 33; wherein, the top of the crushing cylinder 31 is connected to the bottom of the crushing bucket 21; the sides and bottom of the crushing cylinder 31 are provided with a plurality of first screen holes 311; the sides of the crushing cylinder 31 are fixedly connected to the mounting frame 4; the crushing cylinder 31 is located above the screening mechanism 5; one end of the driving assembly 32 is connected to the mounting plate 1, and the other end extends from the top of the crushing cylinder 31 into the crushing cylinder 31; the crushing assembly 33 is connected to the end of the driving assembly 32 located inside the crushing cylinder 31.

[0026] It should be noted that the top of the crushing cylinder 31 is provided with an opening, which connects to the crushing bucket 21. Small pieces of lees output from the first crushing mechanism 2 enter the crushing cylinder 31 through this opening. During operation, one end of the drive component 32 is mounted on the mounting plate 1, and the other end extends from the top of the crushing cylinder 31 into the crushing cylinder 31, driving the crushing component located inside the crushing cylinder 31. The driven crushing component 33 performs crushing operations inside the crushing cylinder 31, crushing the small pieces of lees to obtain lees fragments. The obtained lees fragments fall directly into the screening mechanism 5 through the first screen holes 311 at the bottom and side walls of the crushing cylinder 31. Impurities larger than the first screen holes 311 are screened and remain in the crushing cylinder 31. This achieves the crushing of large pieces of lees into small pieces of lees and the screening of large-sized impurities in the small pieces of lees.

[0027] As an optional implementation of this embodiment, the drive assembly 32 further includes a second motor 321, a thick gear 322, a first thin gear 323, a second thin gear 324, a vertical rod 325, and a sleeve 326; wherein, the second motor 321 is disposed on the top of the mounting plate 1; the output shaft of the second motor 321 extends from the top of the mounting plate 1 to the bottom of the mounting plate 1; the thick gear 322 is fixedly connected to the output shaft of the second motor 321; the thick gear 322 is located below the mounting plate 1; The first thin gear 323 and the second thin gear 324 are coaxially meshed on one side of the thick gear 322; the first thin gear 323 is located above the second thin gear 324; one end of the vertical rod 325 is fixedly connected to the first thin gear 323; the end of the vertical rod 325 near the first thin gear 323 is also rotatably connected to the center of the second thin gear 324; the end of the vertical rod 325 away from the first thin gear 323 passes through the top of the crushing cylinder 31 and is connected to the crushing assembly 33; the sleeve 326 is movably sleeved on the vertical rod 325; one end of the sleeve 326 is fixedly connected to the second thin gear 324, and the other end passes through the crushing cylinder 31 and is connected to the crushing assembly 33.

[0028] It should be noted that a retaining ring is provided between the second thin gear 324 and the vertical rod 325 to limit the movement of the second thin gear 324 in the axial direction of the vertical rod 325. After the drive assembly is started, the second motor 321 rotates, driving the thick gear 322 located below the mounting plate 1 to rotate. The thick gear 322 meshes with the first thin gear 323 and the second thin gear 324, which are coaxially arranged on one side. The first thin gear 323 is located above the second thin gear 324, that is, the first thin gear 323 and the second thin gear 324 are aligned in the vertical direction. Then, through the rotation of the thick gear 322, the first thin gear 323 and the second thin gear 324 are synchronously driven to rotate simultaneously. Then, the vertical rod 325 rotates. The end of the vertical rod 325 is fixedly connected to the first thin gear 323; the end of the vertical rod 325 near the first thin gear 323 is also rotatably connected to the center of the second thin gear 324, and the end of the vertical rod 325 away from the first thin gear 323 passes through the top of the crushing cylinder 31 and is connected to the crushing assembly 33; therefore, when the first thin gear 323 rotates, it will drive the vertical rod 325 to rotate synchronously; and the second thin gear 324 is rotatably connected to the vertical rod 325, so when the second thin gear 324 rotates, it will drive the sleeve 326 movably sleeved on the vertical rod 325 to rotate independently; thereby realizing the independent rotation of the vertical rod 325 and the sleeve 326 in the crushing cylinder 31, thereby driving the crushing assembly 33 to carry out crushing operations in the crushing cylinder 31.

[0029] As an optional implementation of this embodiment, the crushing assembly 33 further includes a horizontal plate 331, two first crushing rollers 332, a third rotating shaft 333, a fourth rotating shaft 334, a first driven gear 335, a second driven gear 336, a driving gear 337, and two second crushing rollers 338; wherein, the top of the horizontal plate 331 is fixedly connected to one end of the vertical rod 325 located inside the crushing cylinder 31; the two first crushing rollers 332 are respectively disposed on both sides of the bottom of the horizontal plate 331; the two first crushing rollers 332 are coaxially disposed; the third rotating shaft 333 and the fourth rotating shaft 334 are respectively vertically disposed on both sides of the top of the horizontal plate 331; the third rotating shaft 335... Both the third and fourth rotating shafts 333 and 334 are rotatably connected to the horizontal plate 331; the first driven gear 335 and the second driven gear 336 are respectively fixedly sleeved on the third rotating shaft 333 and the fourth rotating shaft 334; the driving gear 337 is set on the cross section of the sleeve 326 near the horizontal plate 331; the driving gear 337 is penetrated by the vertical rod 325; the driving gear 337, the first driven gear 335 and the second driven gear 336 are located at the same height; the driving gear 337, the first driven gear 335 and the second driven gear 336 are connected by chain drive; the two second crushing rollers 338 are respectively fixedly sleeved on the third rotating shaft 333 and the fourth rotating shaft 334.

[0030] It should be noted that when the vertical rod 325 rotates, it drives the horizontal plate 331 to perform circular motion within the crushing cylinder 31. The two coaxially arranged first crushing rollers 332 are respectively rotated on both sides of the bottom of the horizontal plate 331, so the two first crushing rollers 332 also perform circular motion around the center of the horizontal plate 331. Since the first crushing rollers 332 are rotated at the bottom of the horizontal plate 331, during the process of crushing the distiller's grains in circular motion, when crushing the distiller's grains located at the bottom of the crushing cylinder 31, they also rotate around their own central axis after friction with the distiller's grains, thereby increasing the crushing rate. Simultaneously, the third rotating shaft 333 and the fourth rotating shaft 334 are vertically arranged on both sides of the top of the horizontal plate 331, and the two second crushing rollers 338 are respectively fixedly sleeved on the third rotating shaft 333 and the fourth rotating shaft 334. Therefore, when the horizontal plate 331 moves in a circular motion, it also drives the two vertically arranged second crushing rollers 338 to rotate around the center of the horizontal plate 331. The center of the sleeve 326 rotates in a circular motion. The first driven gear 335 and the second driven gear 336 are fixedly mounted on the third rotating shaft 333 and the fourth rotating shaft 334, respectively. The driving gear 337 is located on the cross section of the sleeve 326 near the horizontal plate 331. The driving gear 337 is penetrated by the vertical rod 325. The driving gear 337, the first driven gear 335, and the second driven gear 336 are at the same height. The driving gear 337, the first driven gear 335, and the second driven gear 336 are connected by a chain drive. Therefore, the rotation of the sleeve 326 drives the driving gear 337 to rotate, and synchronously drives the first driven gear 335 and the second driven gear 336 to rotate through the chain. This, in turn, drives the third rotating shaft 333 and the fourth rotating shaft 334 to rotate around their own central axis on the horizontal plate 331. Ultimately, the two second crushing rollers 338 rotate around the center of the horizontal plate 331 while also rotating on their own axis, thus further improving the crushing efficiency.

[0031] As an optional implementation of this embodiment, the screening mechanism 5 further includes a enclosure 51, a screen plate 52, a toggle assembly 53, and a feeding hopper 54; wherein, the enclosure 51 is fixedly connected to the mounting frame 4; surrounds the outside of the crushing cylinder 31; a gap is provided between the enclosure 51 and the crushing cylinder 31; two opposing first through slots 511 and two opposing second through slots 512 are provided on both sides of the enclosure 51; the first through slots 511 and the second through slots 512 are located at the same height; the screen plate 52 is fixedly installed. Inside the enclosure 51; the screen plate 52 is provided with a plurality of uniform second screen holes 521; the screen plate 52 is located below the crushing cylinder 31; both ends of the actuating component 53 are connected to the first through groove 511 and the second through groove 512; the actuating component 53 is located above the screen plate 52; the actuating component 53 slides in the first through groove 511 and the second through groove 512 to actuate the lees on the screen plate 52; the feeding hopper 54 is aligned and set at the bottom of the enclosure 51; the top of the feeding hopper 54 is fixedly connected to the bottom of the enclosure 51.

[0032] It should be noted that the enclosure 51 blocks the broken lees coming out of the side wall of the crushing cylinder 31, reducing the chance of the lees falling outside the device. Simultaneously, the enclosure 51 also serves as a mounting component for the screen plate 52, the actuating assembly 53, and the discharge hopper 54. Two first through slots 511 are provided, one on one side of the enclosure 51 and the other on the opposite side. Similarly, two second through slots 512 are respectively provided on the opposite side of the enclosure 51 where the two first through slots 511 are located. One side of the channel 511 and the other side are at the same height; during operation, the agitator 53 is activated, and the agitator 53 slides in the two opposite first channels 511 and the two opposite second channels 512 on the opposite sides of the enclosure 51, repeatedly agitating the lees fragments that fall on the screen plate 52, improving the efficiency of the lees fragments passing through the second screen hole 521, and thus improving the screening efficiency of small impurities in the lees fragments 521; the lees fragments that pass through the second screen hole 521 are directly fed through the feed hopper 54, thereby obtaining the screened lees fragments.

[0033] As an optional implementation of this embodiment, the actuating assembly 53 further includes a first actuating plate 531, a second actuating plate 532, a drive shaft 533, a connecting rod 534, a first connecting rod 535, a second connecting rod 536, and a third motor 537; wherein, the two ends of the first actuating plate 531 are slidably connected to two first through slots 511 respectively; the two ends of the second actuating plate 532 are slidably connected to two second through slots 512 respectively; both the first actuating plate 531 and the second actuating plate 532 are provided with a plurality of evenly arranged actuating rods 530; the drive shaft 533 is rotatably disposed on one side of the enclosure 51; the drive shaft 533 is located between the first through slot 511 and the second through slot 512 on the same side; a first sleeve 5 is fixedly sleeved on one end of the drive shaft 533 near the enclosure 51. 331; Connecting rod 534 is located at the end of drive shaft 533 away from enclosure 51; the middle part of connecting rod 534 is fixedly connected to drive shaft 533; one end of first connecting rod 535 is rotatably connected to the end of connecting rod 534 near first actuating plate 531, and the other end is rotatably connected to the end of first actuating plate 531 near drive shaft 533; one end of second connecting rod 536 is rotatably connected to the end of connecting rod 534 away from first connecting rod 535, and the other end is rotatably connected to the end of second actuating plate 532 near drive shaft 533; third motor 537 is located on the side of enclosure 51 where drive shaft 533 is located; second sleeve 5371 is fixedly sleeved on the output shaft of third motor 537; first sleeve 5331 and second sleeve 5371 are connected by belt drive.

[0034] It should be noted that the third motor 537 is a stepper motor. By controlling the forward and reverse rotation of the third motor 537, the second sleeve 5371 is driven to rotate forward. The forward rotation of the second sleeve 5371 and the first sleeve 5331 are connected by a belt drive, which in turn drives the second sleeve 5371 to rotate in both directions. The second sleeve 5371 is fitted onto the drive shaft 533, thereby realizing the forward and reverse rotation of the drive shaft 533. During operation, the third motor 537 rotates forward, driving the drive shaft 533 to rotate forward, which in turn drives the connecting rod 534 to rotate forward around its own center. Its two ends are respectively rotatably connected to the first connecting rod. 535 and second connecting rod 534, the ends of the first connecting rod 535 and second connecting rod 534 away from the rotating shaft 533 are respectively connected to the first actuating plate 531 and the second actuating plate 532, the first actuating plate 531 and the second actuating plate 532 are respectively slidably disposed in the first through groove 511 and the second through groove 512; therefore, when the third motor 537 rotates forward, it drives the connecting rod 534 to rotate forward around its own center, thereby driving the first connecting rod 535 and the second connecting rod 536 to rotate, which in turn causes the first connecting rod 535 to pull the first actuating plate 531 along The first through groove 511 slides towards the connecting rod 534, while the second connecting rod 536 pulls the second actuating plate 532 to slide along the second through groove 512 towards the connecting rod 534, thus moving the first actuating plate 531 and the second actuating plate 532 closer to each other. Both the first actuating plate 531 and the second actuating plate 532 are provided with multiple evenly arranged actuating rods 530, which actuate the lees fragments on the sieve plate 52 during the movement process. Subsequently, the third motor 537 is controlled to reverse, thereby reversing the connecting rod 534. This causes the first connecting rod 535 to pull the first actuating plate 531 to slide along the first through groove 511 away from the connecting rod 534, while the second connecting rod 536 pulls the second actuating plate 532 to slide along the second through groove 512 away from the connecting rod 534, thus realizing the movement of the first actuating plate 531 and the second actuating plate 532 away from each other; during the movement process, the actuating plate 530 actuates the lees fragments on the sieve plate 52; by setting the forward and reverse rotation of the third motor 537, the back and forth actuation of the lees fragments on the sieve plate 52 is realized, thereby improving the screening efficiency.

[0035] As an optional implementation of this embodiment, the device further includes a collection box 6, which is aligned and disposed at the bottom of the hopper 54; the top of the collection box 6 is detachably connected to the bottom of the hopper 54.

[0036] It should be noted that the collection box 6 is located at the bottom of the feed hopper 54, which can directly collect the screened lees. It is also detachable, so that after it is full of lees, it can be removed and packaged for storage.

[0037] The working principle of the integrated crushing and screening device for distiller's grains according to this embodiment is as follows: First, the first motor 26 rotates, synchronously driving the second shaft 23 and the first shaft 22 to rotate in opposite directions, so that the first crushing blade 221 and the second crushing blade 231 rotate in opposite directions. This allows the first crushing blade 221 and the second crushing blade 231 to shear and crush the large pieces of lees falling between them, resulting in smaller pieces of lees. These smaller pieces of lees enter the crushing cylinder 31 through the opening at the bottom of the crushing hopper 21. At this time, the second motor 321 rotates, driving the vertical rod 325 and the sleeve 326 to rotate independently. When the vertical rod 325 rotates, the two first crushing rollers 332, located at the bottom of the horizontal plate 331, move in a circular motion around the center of the horizontal plate 331, and the second crushing rollers 338, located on both sides of the top of the horizontal plate 331, also move in a circular motion around the horizontal plate 331. During the process of crushing the lees pieces in their circular motion, the two first crushing rollers 332 crush the lees pieces located at the bottom of the crushing cylinder 31, causing friction with the lees pieces. After friction, it will also rotate around its own central axis; at the same time, the rotation of the sleeve 326 drives the drive gear 337 to rotate, and through the chain, it synchronously drives the first driven gear 335 and the second driven gear 336 to rotate, which in turn drives the third rotating shaft 333 and the fourth rotating shaft 334 to rotate around their own central axis on the horizontal plate 331. Finally, the two second crushing rollers 338 rotate around the center of the horizontal plate 331 while also rotating themselves; the crushed lees fall into the screen plate 52 through the first screen hole 311; through the forward and reverse rotation of the third motor 537, the first actuating plate 531 and the second actuating plate 532 reciprocate by moving closer and further away from each other, and then through the actuating rod 530 at the bottom of the first actuating plate 531 and the second actuating plate 532, the lees on the screen plate 52 are moved back and forth to achieve the screening of the lees; after screening, the lees enter the collection box 6 through the feed hopper 54.

[0038] According to an embodiment of the integrated device for crushing and screening distiller's grains, a first crushing mechanism, a second crushing mechanism, and a screening mechanism are vertically integrated along the material flow direction. After large pieces of distiller's grains enter, they undergo preliminary shearing and secondary fine crushing. The resulting grain fragments fall directly into the screening mechanism below for sieving, eliminating intermediate transfer equipment, significantly shortening the process flow, and truly achieving one-stop continuous production. A two-stage crushing structure is adopted: the first crushing mechanism shears large pieces of distiller's grains into smaller pieces; the second crushing mechanism crushes and refines the smaller pieces through grinding and rubbing. This step-by-step processing from coarse to fine crushing ensures a more uniform particle size in the output distiller's grains, providing favorable conditions for subsequent drying and other processes. In the second crushing mechanism, the first crushing roller moves in a circular motion with the horizontal plate, relying on friction with the material to achieve rotation and crush the bottom lees; at the same time, the second crushing roller rotates actively while revolving around the central plate; the combined motion of the two sets of crushing rollers effectively increases the area and frequency of action on the material, significantly improving crushing efficiency and fine crushing capability; the screening mechanism is equipped with a pair of first and second actuating plates that can be driven by the first and second connecting rods to reciprocate, and move back and forth on the screen plate through the actuating rods at the bottom of the two plates, continuously turning and dispersing the accumulated lees fragments, breaking the material bridging, and allowing qualified lees fragments to quickly pass through the screen holes; this design effectively avoids screen plate clogging and ensures the continuity of the screening process and the separation accuracy.
