A limiting groove is opened on the inner side of the upper end of the support plate, and an electric telescopic rod is fixedly connected to the inner side of the limiting groove. A built-in drive device is installed inside the fermentation body assembly, and a stirring assembly is installed inside the built-in drive device. The fermentation body assembly includes a fermentation shell, with a material valve opening at the bottom of the fermentation shell. An upper mounting plate is fixedly connected to the inner side of the upper end of the fermentation shell.

[0004] Based on the description in the above documents, in the fermentation process of existing fermentation devices, the mixing of raw materials often results in stratification or accumulation of raw materials at the bottom, causing the materials to rotate only in a horizontal position, resulting in uneven mixing. Furthermore, when encountering clumps or accumulated raw materials during the mixing process, forceful operation can damage the components designed to solve the problem of uneven mixing. Therefore, the present invention provides an intelligent fermentation device and method based on the processing of distillers' grains organic fertilizer. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent fermentation device and method based on the processing of organic fertilizer from distiller's grains. This invention solves the problems that existing fermentation devices often have issues such as layering or accumulation of raw materials at the bottom during fermentation, resulting in uneven mixing because the materials rotate only in a horizontal position. Furthermore, the invention addresses the problem that forceful operation can damage the components designed to solve the problem of uneven mixing when encountering clumps or accumulated raw materials during the mixing process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent fermentation device based on the processing of distiller's grains organic fertilizer, comprising a mixed fermentation tank, the top of which is fitted with a detachable lid, and the bottom of which is connected and fixed with a conical tank bottom, the bottom of which is fitted with a bottom support frame. The interior of the mixed fermentation tank is equipped with a turning mechanism for the mixed fermentation of distiller's grains raw materials, and the turning mechanism includes:

[0007] The drive unit includes a central cylinder located at the center of the mixed fermentation tank. The top of the central cylinder rotates by a drive component provided at the tank cover, while the upper and lower material tipping unit rotates by a meshing component provided inside the central cylinder.

[0008] The upper and lower turning section, driven by the drive unit, achieves synchronous rotation in the horizontal and vertical directions and completes the turning operation during raw material fermentation. It includes a cylinder located outside the central cylinder, with four sets of turning hoppers arranged in a circumferential shape on the surface of the cylinder. Auxiliary plates are installed on the symmetrical sides of the turning hoppers in the front and rear directions. The auxiliary plates are equipped with sensors to determine the resistance to the raw materials during the turning process and crushing components to crush the raw materials when the resistance exceeds the requirements.

[0019] A stop spring is fitted on the surface of the connecting rod, and the two ends of the stop spring are fixed to the opposite sides of the fixed plate and the upper contact plate. At the same time, the reset force of the stop spring, which is not affected by other external forces, causes the sensing plate to move in the direction of the hopper rotation process.

[0020] Preferably, the crushing component includes:

[0021] A miniature electric actuator is installed at the bottom of the inner cavity of the auxiliary plate, and after the miniature electric actuator is started, it drives the connected and fixed push rod to move in the vertical direction.

[0023] Preferably, a lower contact plate is installed at the bottom of the inner cavity of the auxiliary plate, on one side of the micro electric push rod, and a control box with power supply function is installed in the empty space of the inner cavity of the auxiliary plate. The power supply terminal of the control box is electrically connected to the upper and lower contact plates through wires. The upper and lower contact plates are provided with electrical contact points on opposite sides to complete the electrical connection after contact. When the upper and lower contact plates contact, the control terminal of the control box generates a start command and transmits it to the micro electric push rod to control the crushing bar to crush the raw material in the rotation direction of the tipping hopper.

[0031] This invention also discloses an intelligent fermentation method based on the processing of distiller's grains organic fertilizer, specifically including the following steps:

[0033] S2. The upper and lower turning parts are driven by the drive unit to complete the stirring and turning operation of the raw material fermentation, and oxygen supply is achieved by the oxygen inlet pipe.

[0034] S3. After fermentation is complete, the product is fed out using the feeding control device.

[0035] This invention provides an intelligent fermentation device and method based on the processing of distiller's grains into organic fertilizer. Compared with the prior art, it has the following advantages:

[0036] 1. This intelligent fermentation device and method based on the processing of organic fertilizer from distiller's grains features a turning mechanism. Driven by a drive unit, the upper and lower turning parts complete the stirring and turning operations during raw material fermentation. The rotation of the central cylinder causes the turning hopper to rotate laterally around the central cylinder, and with the help of meshing parts, it achieves longitudinal rotation around the outer axis of the turning hopper. This keeps the moving trajectory of the turning hopper curved and achieves synchronous operation of lateral and longitudinal rotation, which better realizes the turning operation, making the raw materials in the mixed fermentation tank more uniformly mixed, and continuously changing the depth of materials at different depths, thereby improving the mixing efficiency during fermentation.

[0037] 2. This intelligent fermentation device and method based on the processing of organic fertilizer from distiller's grains uses a turning hopper to turn the material. When the induction plate experiences greater resistance, the upper contact plate moves closer to the lower contact plate until the electrical contact points of the upper and lower contact plates make contact. Then, the control terminal of the control box generates a start command and transmits it to the micro electric push rod to control the crushing bar to crush the raw material in the direction of the turning hopper's rotation. This process, based on the force conditions during real-time turning, handles agglomerated and piled raw materials, ensuring better combination of different materials during fermentation and improving the uniformity of material contact.

[0038] 3. This intelligent fermentation device and method based on the processing of organic fertilizer from distiller's grains uses a feeding control component. A small motor drives the rotation of a control plate. When the control plate rotates to align with the center of the feeding trough, the feeding trough is closed; conversely, when the control plate rotates to an empty position, the feeding trough is opened. Then, the feeding pump is activated to provide suction and discharge the product. This avoids the problem of unfermented material entering the pipeline prematurely, causing unmixing, and facilitates subsequent feeding processing, enabling better and faster feeding operations.

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please refer to Figures 1-13. This invention provides two technical solutions:

[0055] Example 1: An intelligent fermentation device based on the processing of distiller's grains organic fertilizer includes a mixed fermentation tank 1. The top of the mixed fermentation tank 1 is fitted with a detachable tank cover 2, and the bottom of the mixed fermentation tank 1 is connected and fixed with a conical tank bottom 3. A bottom support frame 4 is installed at the bottom of the conical tank bottom 3. The interior of the mixed fermentation tank 1 is equipped with a turning mechanism for the mixed fermentation of distiller's grains raw materials. The turning mechanism includes:

[0056] The drive unit 5 includes a central cylinder 51 located at the center of the inside of the mixing fermentation tank 1. The top of the central cylinder 51 is rotated by a drive member 52 provided at the tank cover 2, while the upper and lower material turning unit 6 is rotated by a meshing member 53 provided inside the central cylinder 51.

[0057] The upper and lower turning section 6, driven by the drive section 5, achieves synchronous rotation in the horizontal and vertical directions and completes the turning operation during raw material fermentation. It includes a cylinder 61 located outside the central cylinder 51, and four sets of turning hoppers 62 are arranged in a circumferential shape on the surface of the cylinder 61. Auxiliary plates 63 are installed on the symmetrical sides of the turning hoppers 62 in the front and rear directions. The auxiliary plates 63 are equipped with sensors 64 to determine the resistance to the raw materials during the turning process and crushing components 65 to crush the raw materials when the resistance exceeds the requirements.

[0058] By setting up a turning mechanism, the upper and lower turning parts 6 are driven by the drive unit 5 to complete the stirring and turning operation of the raw materials during fermentation. The rotation of the central cylinder 51 will cause the turning hopper 62 to rotate laterally around the central cylinder 51, and with the cooperation of the meshing part 53, the turning hopper 62 will rotate longitudinally around the outer rotating shaft 532. This keeps the moving trajectory of the turning hopper 62 as curved and realizes the synchronous operation of the lateral and longitudinal rotation, which better realizes the turning operation, makes the raw materials in the mixed fermentation tank 1 more uniformly mixed, and the materials at different depths continuously change depth, improving the mixing efficiency during fermentation.

[0059] Please refer to Figures 3 and 4. In this embodiment of the invention, the driving component 52 includes:

[0060] A drive motor 521 is fixedly installed on the top of the can lid 2, and one end of the output shaft of the drive motor 521 extends to the bottom of the can lid 2 and is connected to a drive shaft 522 via a coupling.

[0061] The auxiliary drive shaft 523 is fixedly installed at the center of the top of the central cylinder 51;

[0062] The bottom end of the drive shaft 522 is provided with a groove 524, and the surface of the auxiliary shaft 523 is equipped with a pin 525. The pin 525 is adapted to the pin groove inside the groove 524, and after the pin 525 slides into the groove 524, the drive shaft 522 rotates and drives the auxiliary shaft 523 to rotate synchronously.

[0063] The drive motor 521 is electrically connected to an external power source and is a three-phase asynchronous motor.

[0064] Please refer to Figures 5-7. In this embodiment of the invention, the meshing member 53 includes:

[0065] The inner rotating shaft 531 is fixedly installed on the partition plate at the top of the conical tank bottom 3, and the inner rotating shaft 531 is connected to the central cylinder 51 for rotation via a bearing;

[0066] An outer rotating shaft 532 passes through the central cylinder 51 and rotates relative to the central cylinder 51. The outer rotating shaft 532 and the central cylinder 51 are connected and rotated through bearings. A longitudinal bevel gear 533 is installed at the end of the outer rotating shaft 532 located inside the central cylinder 51. A transverse bevel gear 534 is fixedly installed on the surface of the inner rotating shaft 531, meshing with the surface of the longitudinal bevel gear 533. When the transverse bevel gear 534 and the longitudinal bevel gear 533 mesh and rotate relative to each other, the outer rotating shaft 532 rotates synchronously.

[0067] Please refer to Figures 8-11. In this embodiment of the invention, the sensing element 64 includes:

[0068] The sensing plate 641 is located above the auxiliary plate 63. During the rotation of the tipping hopper 62, the sensing plate 641 first contacts the raw material in the direction of rotation. The bottom of the sensing plate 641 and the left and right sides are equipped with connecting rods 642.

[0069] A fixed plate 643 is fixedly installed on the inner wall of the auxiliary plate 63. A connecting rod 642 passes through the auxiliary plate 63 and the fixed plate 643 in sequence and extends to the bottom of the fixed plate 643. The connecting rod 642 and the fixed plate 643 are kept in contact and slide relative to each other. An upper contact plate 644 is installed at the bottom of the connecting rod 642.

[0070] A stop spring 645 is sleeved on the surface of the connecting rod 642, and the two ends of the stop spring 645 are fixed to the opposite sides of the fixed plate 643 and the upper contact plate 644. At the same time, the reset elastic force of the stop spring 645, which is not affected by other external forces, causes the sensing plate 641 to move in the direction of the rotation of the tipping hopper 62.

[0071] Please refer to Figures 9 and 12. In this embodiment of the invention, the crushing component 65 includes:

[0072] The miniature electric actuator 651 is installed at the bottom of the inner cavity of the auxiliary plate 63, and after the miniature electric actuator 651 is started, it drives the connected and fixed push rod 652 to move in the vertical direction.

[0073] The crushing bar 653 has a triangular end face and a sharp point facing the direction of rotation. The push rod 652 passes through the auxiliary plate 63 and extends to the outside of the auxiliary plate 63 and is fixed to the crushing bar 653.

[0074] Please refer to Figure 9. In this embodiment of the invention, a lower contact plate 654 is installed at the bottom of the inner cavity of the auxiliary plate 63 on one side of the micro electric push rod 651, and a control box 655 with power supply function is installed in the empty space of the inner cavity of the auxiliary plate 63. The power supply terminal of the control box 655 is electrically connected to the upper contact plate 644 and the lower contact plate 654 through wires. The upper contact plate 644 and the lower contact plate 654 are provided with electrical contact points on opposite sides to complete the electrical connection after contact. When the upper contact plate 644 and the lower contact plate 654 contact, the control terminal of the control box 655 generates a start command and transmits it to the micro electric push rod 651 to control the crushing bar 653 to crush the raw material in the rotation direction of the tipping hopper 62.

[0075] By setting up a turning hopper 62 to turn the material, the sensing plate 641 will experience greater resistance, causing the upper contact plate 644 to move closer to the lower contact plate 654. After the upper contact plate 644 and the lower contact plate 654 make contact, the control terminal of the control box 655 generates a start command and transmits it to the micro electric push rod 651 to control the crushing bar 653 to strike and crush the raw material in the direction of rotation of the turning hopper 62. In this way, the agglomerated raw material and the accumulated raw material are processed according to the force situation during the turning process. While completing the turning process, it ensures better combination of different materials during fermentation and improves the uniformity of contact between materials.

[0076] Among them, the control box 655 with power supply function is an existing mature product, and the operation of the control terminal of the control box 655 generating instructions according to the real-time situation can be completed through the existing control system. The control box 655 with power supply function is connected and controlled with the external main control terminal through a wireless local area network. The entire fermentation device can be disassembled, and the relatively far side of the auxiliary plate 63 can be opened to facilitate charging. The micro electric push rod 651 strikes repeatedly.

[0077] Please refer to Figures 2-3 and 10. In this embodiment of the invention, a feeding control component 7 is provided at the partition at the top of the conical tank bottom 3 for feeding the fermented product. A sweeping plate 8 is installed on the surface of the central cylinder 51, and the sweeping plate 8 is in contact with the partition surface at the top of the conical tank bottom 3. An oxygen inlet pipe 10 is connected to the partition at the top of the conical tank bottom 3.

[0078] The oxygen inlet pipe 10 controls the flow rate through a solenoid valve installed in the conical tank bottom 3 to achieve the oxygen supply operation into the mixed fermentation tank 1. A filter screen is installed at the port of the oxygen inlet pipe 10 to prevent raw materials from flowing into the pipe. The oxygen inlet pipe 10 is connected to an existing external oxygen supply tank. (The attached diagram is not shown.)

[0079] Please refer to Figures 2-3. In this embodiment of the invention, the material feeding control component 7 includes:

[0080] The feeding chute 71 is located on the partition surface at the top of the conical tank bottom 3, and a closing element 9 is provided on the inner side of the feeding chute 71 to control the opening or closing of the feeding chute 71.

[0081] The feed pump 72 is installed at the bottom of the conical tank bottom 3 and provides suction when driven to realize the product feeding operation. The feed pipe of the feed pump 72 is connected and fixed to the bottom edge of the feed trough 71.

[0082] The feed pump 72 is electrically connected to an external power source and is used to realize the material conveying operation. It is an existing mature product.

[0083] Please refer to Figure 13. In this embodiment of the invention, the closure member 9 includes:

[0084] A small motor 91 is installed inside the conical tank bottom 3, and a rotating shaft 92 is installed at one end of the output shaft of the small motor 91;

[0085] The control plate 93 is fixed to the top of the rotating shaft 92, and an empty slot 94 is provided on the partition at the top of the conical tank bottom 3 and on the inner side of the feeding trough 71 for the control plate 93 to be placed after rotation. When the control plate 93 is rotated to align with the center of the feeding trough 71, the feeding trough 71 is closed; otherwise, when the control plate 93 is rotated to the empty slot 94, the feeding trough 71 is opened.

[0086] By setting up a feeding control component 7, the rotation control of the control board 93 is completed by the drive of the small motor 91. When the control board 93 rotates to align with the center of the feeding trough 71, the feeding trough 71 is closed. Conversely, when the control board 93 rotates to the empty trough 94, the feeding trough 71 is opened. Then, the feeding pump 72 is started to provide suction to realize the feeding operation of the product. This avoids the problem of unmixed material entering the pipeline in advance before fermentation, and facilitates subsequent feeding processing, assisting in better and faster feeding operations.

[0087] Example 2 differs from Example 1 in that: the present invention also discloses an intelligent fermentation method based on the processing of distiller's grains organic fertilizer, specifically including the following steps:

[0088] S1. After crushing the raw materials, add them to the mixing fermentation tank 1 according to the proportion;

[0089] S2. The upper and lower turning section 6 completes the stirring and turning operation of the raw material during fermentation by driving the drive section 5, and oxygen supply is achieved by relying on the oxygen inlet pipe 10.

[0090] S3. After fermentation is complete, the product is fed out using the feeding control component 7.

[0091] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0092] During operation, the raw materials are crushed and added to the mixing fermentation tank 1 in proportion. Then, the tank cover 2 is installed on the top of the mixing fermentation tank 1, so that the groove 524 at the bottom of the drive shaft 522 and the pin 525 on the auxiliary shaft 523 can be matched and contacted, so that the drive shaft 522 rotates and drives the auxiliary shaft 523 to rotate synchronously.

[0093] Then, the drive motor 521 is started to drive the drive shaft 522, the auxiliary drive shaft 523 and the central cylinder 51 to rotate synchronously. The rotation of the central cylinder 51 will cause the tipping hopper 62 to rotate laterally with the central cylinder 51 as the center.

[0094] Meanwhile, since the inner rotating shaft 531 and the horizontal bevel gear 534 fixed on the surface do not rotate, the central cylinder 51 drives the longitudinal bevel gear 533 on the outer rotating shaft 532 to mesh and move on the surface of the horizontal bevel gear 534 during the rotation process, thereby realizing the rotation operation of the outer rotating shaft 532. This enables the turning hopper 62 to complete the longitudinal rotation with the outer rotating shaft 532 as the center. At the same time, the movement trajectory of the turning hopper 62 is curved, which effectively ensures that the turning operation is more uniform and complete. During the stirring process, oxygen is delivered to the mixed fermentation tank 1 through the oxygen inlet pipe 10 to maintain air circulation.

[0095] When the tipping hopper 62 rotates longitudinally, the sensing plate 641 first contacts the raw material in the direction of rotation. When encountering agglomerated material, the sensing plate 641 will experience greater resistance and stretch the abutment spring 645. At the same time, the upper contact plate 644 moves closer to the lower contact plate 654 until the electrical contact points of the upper contact plate 644 and the lower contact plate 654 make contact. Then, the control terminal of the control box 655 generates a start command and transmits it to the micro electric push rod 651 to control the crushing bar 653 to strike and crush the raw material in the direction of rotation of the tipping hopper 62. When the resistance no longer causes the electrical contact points of the upper contact plate 644 and the lower contact plate 654 to make contact, the structure resets.

[0096] After the fermentation process is completed, the small motor 91 drives the rotation of the control board 93. When the control board 93 is rotated to align with the center of the feeding trough 71, the feeding trough 71 is closed. Conversely, when the control board 93 is rotated to the empty trough 94, the feeding trough 71 is opened. Then, the feeding pump 72 is started to provide suction to achieve the product feeding operation.

[0097] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
