[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a functional grain processing device, such as... Figure 1-8 As shown, the functional grain processing device includes: a base plate 49; a processing mechanism, a feeding mechanism, a microbial agent spraying mechanism, and a discharging mechanism disposed on the base plate 49; the processing mechanism is used to carry grain and achieve mixing; the feeding mechanism is used to convey grain to the processing mechanism; the microbial agent spraying mechanism is used to spray microbial liquid onto the grain in the processing mechanism; and the discharging mechanism is used to discharge the processed grain.

[0020] In this embodiment, the device is first pre-processed before use. The electric telescopic rod 32 is started, which moves the assembly plate 33, spline rod 36 and connecting plate 31, so that the spline rod 36 is inserted into the first spline cylinder 34. The connecting plate 31 moves the sealing plate 30 to open the feeding hopper 25 channel. Then the bacterial liquid supply equipment is connected to the rotary joint 14. Each component is checked to ensure normal operation. Then the motor 15 is started, which drives the transmission shaft 17 to rotate through the reducer 16 and the first bevel gear 18. Then, the second bevel gear 27, the first rotating shaft 12 and the pulley and transmission belt drive the spiral shaft 24 to rotate, so that the grain is added to the feeding hopper 25 and sent into the mesh cylinder 3 through the spiral shaft 24 and the feeding pipe 22. Dust collection is completed simultaneously during the feeding process. After the grain is fed into the mesh cylinder 3, the liquid supply equipment and motor 15 are started. The bacterial liquid is sprayed onto the surface of the grain from the nozzle 9 through the rotary joint 14, the second channel 13, and the first channel 8. At the same time, the first rotating shaft 12 drives the spline seat 10 to rotate, and the spline seat 10 drives the spline block 11 to rotate, so that the stirring shaft 5, the connecting rod 6, and the stirring plate 7 rotate synchronously to fully mix the grain and the bacterial liquid. During the stirring process, the excess bacterial liquid that is not absorbed in the mesh cylinder 3 seeps into the bottom of the processing box 1. The solenoid valve 29 is opened in time to discharge the excess bacterial liquid through the drain pipe 28 and then closed to reduce the impact of bacterial liquid residue on the processing quality. After mixing is complete, the motor 15 and liquid supply equipment are turned off, and the electric hydraulic rod 20 is started, which drives the connecting frame 21 and the second side plate 4 to separate. The pusher plate 19 moves with the stirring shaft 5, pushing the processed grain in the mesh cylinder 3 to the discharge trough 26 for discharge. After processing, all equipment is turned off and all components are reset. This device integrates feeding, dust removal, microbial agent spraying, mixing and discharging functions, reducing manual intervention and lowering the risk of contamination during processing. Microbial agent spraying and mixing are carried out simultaneously to improve inoculation uniformity. Excess microbial liquid can be discharged in time to avoid residue accumulation, thereby improving processing quality and efficiency. The protective shell shields the motor 15 and reducer 16 for protection, and the heat dissipation vents ensure stable operation of the equipment.

[0021] In a further preferred embodiment of the present invention, the processing mechanism includes: a processing box 1, a mesh cylinder 3, a stirring assembly, and a driving assembly; a first side plate 2 and a second side plate 4 are respectively provided on both sides of the processing box 1, the first side plate 2 is fixedly connected to the processing box 1 by bolts, and the second side plate 4 can be separated from the processing box 1; the mesh cylinder 3 is disposed inside the processing box 1; the stirring assembly is rotatably installed inside the processing box 1 and extends into the mesh cylinder 3 for stirring the grain inside the mesh cylinder 3; the driving assembly is disposed on one side of the processing box 1 for providing driving force to the stirring assembly.

[0022] In this embodiment, when the processing mechanism is in use, the first side plate 2 is first fixedly connected to the processing box 1 with bolts, the mesh cylinder 3 is placed inside the processing box 1, the stirring component is rotated and installed inside the processing box 1 and extends into the mesh cylinder 3, and then the drive component is installed on one side of the processing box 1 to ensure that the drive component and the stirring component can be connected by transmission. After the processing mechanism is assembled, it is used in conjunction with other mechanisms of the device to carry out subsequent grain processing operations. During processing, the drive assembly is activated, which provides driving force to the stirring assembly, causing the stirring assembly to rotate inside the mesh cylinder 3, thereby stirring and mixing the grain inside the mesh cylinder 3. The mesh cylinder 3 can bear and limit the grain, preventing the grain from scattering into the processing box 1. The first side plate 2 is fixed to the processing box 1 with bolts, which can ensure the stability of the stirring assembly when rotating. The second side plate 4 is kept in contact with the processing box 1 to ensure the sealing of the inside of the processing box 1. After grain processing is completed, the second side plate 4 can be separated from the processing box 1, facilitating cleaning and maintenance of the interior of the processing box 1 and the mesh cylinder 3. It can also be used in conjunction with the discharge mechanism to quickly discharge the processed grain from the mesh cylinder 3. This processing mechanism has a compact structure and is easy to assemble. Through the cooperation of the mesh cylinder 3 and the stirring component, the grain mixing effect can be effectively improved. The setting of the first side plate 2 and the second side plate 4 not only ensures processing stability but also improves the convenience of device maintenance and discharge. The drive component provides a stable driving force for the stirring component, ensuring the continuity of the processing process.

[0023] In a further preferred embodiment of the present invention, the stirring assembly includes: a stirring shaft 5, a connecting rod 6, and a stirring plate 7; the stirring shaft 5 is rotatably mounted on the first side plate 2 via a sealed bearing; the connecting rod 6 is uniformly fixed on the stirring shaft 5; the stirring plate 7 is fixed to the end of the connecting rod 6 away from the stirring shaft 5, and the stirring plate 7 is adapted to the inner wall of the mesh cylinder 3 for stirring grain; a first channel 8 is provided inside the stirring shaft 5, and nozzles 9 are uniformly installed on the side of the stirring shaft 5 facing the mesh cylinder 3, the nozzles 9 being connected to the first channel 8 for spraying bacterial solution.

[0024] In this embodiment, during the processing, the drive component drives the stirring shaft 5 to rotate, the stirring shaft 5 drives the connecting rod 6 to rotate synchronously, and then drives the stirring plate 7 to rotate inside the mesh cylinder 3, stirring and mixing the grain inside the mesh cylinder 3. The stirring plate 7 is adapted to the inner wall of the mesh cylinder 3, which can reduce grain residue. At the same time, the bacterial liquid delivered by the bacterial agent spraying mechanism enters the first channel 8 of the stirring shaft 5, and is then evenly sprayed onto the rotating grain surface through the nozzle 9, so that the bacterial liquid and grain can be stirred and inoculated simultaneously, improving the mixing effect. After processing, stop the rotation of the stirring shaft 5 to clean the nozzle 9, preventing residual bacterial solution from clogging it. The sealed bearing prevents bacterial solution or grain debris from seeping into the connection, ensuring the flexibility of the stirring shaft 5. This stirring assembly has a simple structure and is easy to assemble. The evenly distributed connecting rods 6 can drive the stirring plate 7 to achieve all-round stirring of the grain. The cooperation between the nozzle 9 and the first channel 8 combines bacterial solution spraying with grain stirring, reducing separate operation steps and improving the uniformity of bacterial solution inoculation, thus ensuring processing quality.

[0025] In a further preferred embodiment of the present invention, the drive assembly includes: a motor 15, a reducer 16, a transmission shaft 17, two first bevel gears 18, a first rotating shaft 12, a spline seat 10, a spline block 11, and two second bevel gears 27; the motor 15 and the reducer 16 are both fixed on the base plate 49, and the output shaft of the motor 15 is fixedly connected to the input shaft of the reducer 16 via a coupling; the transmission shaft 17 is rotatably mounted on the base plate 49 via a bearing seat; the two first bevel gears 18 are respectively fixed on the output shaft of the reducer 16 and the transmission shaft 17, and the two first bevel gears 18 are fixed on the output shaft of the reducer 16 and the transmission shaft 17, respectively. The first bevel gears 18 mesh with each other; the spline seat 10 is rotatably mounted on the first side plate 2 via a sealed bearing; the first rotating shaft 12 is fixed on the spline seat 10, and a second channel 13 adapted to the first channel 8 is opened on the first rotating shaft 12. The liquid inlet end of the first channel 8 is fixedly connected to a rotary joint 14 for connecting a bacterial liquid supply device; the two second bevel gears 27 are respectively fixed on the transmission shaft 17 and the first rotating shaft 12 and mesh with each other; a spline block 11 is fixedly sleeved on the stirring shaft 5, and the spline block 11 is inserted into the spline seat 10.

[0026] In this embodiment, during the processing, the motor 15 is started, and the output shaft of the motor 15 drives the reducer 16 to rotate. The output shaft of the reducer 16 drives the first bevel gear 18 on it to rotate, which in turn drives the other first bevel gear 18 and the transmission shaft 17 to rotate. The transmission shaft 17 drives the second bevel gear 27 on it to rotate, which in turn drives the other second bevel gear 27 and the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the spline seat 10 to rotate, and the spline seat 10 drives the stirring shaft 5 to rotate through the spline block 11, providing a stable driving force for the stirring assembly. At the same time, the bacterial liquid supplied by the bacterial liquid supply equipment enters the second channel 13 of the first rotating shaft 12 through the rotary joint 14, and then flows into the first channel 8 of the stirring shaft 5, cooperating with the nozzle 9 to complete the bacterial liquid spraying, realizing the synchronous transmission of driving force and bacterial liquid delivery. After processing is completed, the motor 15 is turned off to stop the drive force output. Components such as the rotary joint 14, the first bevel gear 18, and the second bevel gear 27 can then be inspected and maintained to prevent impurities from accumulating and affecting the transmission effect. This drive assembly is easy to assemble. The transmission speed can be adjusted via the reducer 16 to ensure smooth rotation of the stirring shaft 5. The cooperation between the two first bevel gears 18 and the two second bevel gears 27 enables the conversion of the power direction. The cooperation between the spline seat 10 and the spline block 11 facilitates the disassembly and maintenance of the stirring shaft 5. At the same time, the first rotating shaft 12 integrates a bacterial liquid conveying channel, simplifying the device structure, reducing the space occupied by components, and ensuring the continuity and stability of the processing.

[0027] In a further preferred embodiment of the present invention, the feeding mechanism includes: a feeding cylinder 23, a feeding hopper 25, a screw shaft 24, a feeding pipe 22, and a transmission assembly; the feeding cylinder 23 is fixed to the top of the processing box 1; the feeding hopper 25 is fixed to the top of the feeding cylinder 23; one end of the feeding pipe 22 is connected to the feeding cylinder 23, and the other end of the feeding pipe 22 is connected to the mesh cylinder 3; the screw shaft 24 is rotatably mounted inside the feeding cylinder 23 via bearings and is used to transport grain; the transmission assembly is connected to the screw shaft 24 and is used to drive the screw shaft 24 to rotate.

[0028] In this embodiment, during the processing, the drive component provides driving force to the transmission component, which drives the screw shaft 24 to rotate inside the feed cylinder 23. The operator adds the grain to be processed into the feed hopper 25. Under the action of its own gravity and the rotation of the screw shaft 24, the grain is transported to the bottom of the feed cylinder 23 and then fed into the mesh cylinder 3 through the feed pipe 22, realizing the orderly transport of grain, which can reduce the frequency of direct contact between humans and grain and reduce the risk of processing pollution. After feeding is completed, the rotation of the transmission assembly and the screw shaft 24 is stopped, allowing for the cleaning of the feeding hopper 25, feeding cylinder 23, and screw shaft 24 to prevent grain residue from clumping and affecting subsequent use. This feeding mechanism has a simple structure and is easy to assemble. The screw shaft 24 ensures continuous and stable grain transport, preventing blockages during feeding. The feeding pipe 22 is directly connected to the mesh cylinder 3, allowing grain to be directly fed into the processing area, reducing transfer steps. Combined with the transmission assembly, the feeding rhythm can be flexibly controlled, improving processing convenience and efficiency.

[0029] In a further preferred embodiment of the present invention, the transmission assembly includes: a first splined cylinder 34 rotatably mounted on the processing box 1 via a bearing seat; a second splined cylinder 35 fixed on the spiral shaft 24; an electric telescopic rod 32 fixed on the feed cylinder 23, with an assembly plate 33 fixedly mounted on the push rod of the electric telescopic rod 32; a splined rod 36 rotatably mounted on the assembly plate 33 via a bearing, one end of the splined rod 36 being inserted into the second splined cylinder 35, and the other end of the splined rod 36 being insertable into the first splined cylinder 34; a first pulley 37 and a second pulley 38 respectively fixed on the first rotating shaft 12 and the first splined cylinder 34; and a first transmission belt 39 sleeved on the first pulley 37 and the second pulley 38.

[0030] In this embodiment, during material feeding, the electric telescopic rod 32 is activated, driving the assembly plate 33 and spline rod 36 to move, so that the other end of the spline rod 36 is inserted into the first spline cylinder 34. The drive assembly drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the first pulley 37 to rotate, and through the first transmission belt 39 drives the second pulley 38 and the first spline cylinder 34 to rotate. The first spline cylinder 34 drives the spline rod 36 to rotate, and the spline rod 36 drives the spiral shaft 24 to rotate through the second spline cylinder 35, thereby realizing grain conveying. When no feeding is needed, the electric telescopic rod 32 retracts, driving the spline rod 36 to separate from the first spline cylinder 34, stopping the rotation of the spiral shaft 24. After processing, the wear of the spline rod 36, the first spline cylinder 34, and the pulleys can be inspected, and impurities can be cleaned in a timely manner to ensure smooth transmission. This transmission assembly has a compact structure and is easy to assemble. The connection and separation of the spline rod 36 and the first spline cylinder 34 can be flexibly controlled via the electric telescopic rod 32, realizing the start and stop control of the spiral shaft 24. Together with the two pulleys and the transmission belt, it can stably transmit the power of the drive assembly, ensuring smooth rotation of the spiral shaft 24, thereby improving the stability of the feeding and conveying process, while reducing unnecessary power consumption, and adapting to the usage requirements of the feeding mechanism.

[0031] In a further preferred embodiment of the present invention, the discharge mechanism includes: an electric hydraulic rod 20 fixed on the processing box 1; a connecting frame 21 fixed on the electric hydraulic rod 20; a pusher plate 19 rotatably mounted on the stirring shaft 5 via bearings, the edge of the pusher plate 19 being in contact with the inner wall of the mesh cylinder 3; and a discharge trough 26 fixed on one side of the processing box 1.

[0032] In this embodiment, after the grain processing and mixing are completed, the drive assembly and liquid supply equipment are turned off, and the electric hydraulic rod 20 is started. The push rod of the electric hydraulic rod 20 extends and drives the connecting frame 21 to move, thereby causing the second side plate 4 to separate from the processing box 1. The stirring shaft 5 moves with the second side plate 4, and the spline block 11 on it separates from the spline seat 10. At the same time, the stirring shaft 5 drives the pusher plate 19 to rotate and move synchronously. The pusher plate 19 pushes the grain in the mesh cylinder 3, so that the grain is discharged through the opening of the second side plate 4 and falls into the discharge trough 26, realizing orderly discharge. After discharge is completed, the electric hydraulic rod 20 is turned off, causing its push rod to retract and reset the connecting frame 21, the second side plate 4, and the stirring shaft 5. The spline block 11 is then reinserted into the spline seat 10, allowing for the cleaning of the pusher plate 19 and the discharge chute 26 to prevent grain residue from clumping. This discharge mechanism has a simple structure and is easy to assemble. The electric hydraulic rod 20 enables the opening and closing of the second side plate 4 and the movement of the pusher plate 19. The pusher plate 19 fits snugly against the inner wall of the mesh cylinder 3 to reduce grain residue, while the discharge chute 26 guides the grain to discharge in an orderly manner, reducing spillage and pollution, improving the convenience and efficiency of discharge, and adapting to the overall processing needs of the device.

[0033] In a further preferred embodiment of the present invention, a drain pipe 28 is fixedly connected to the bottom of the processing box 1, and a solenoid valve 29 is provided on the drain pipe 28 for discharging excess bacterial liquid collected in the processing box 1.

[0034] In this embodiment, during the process of spraying the microbial agent and mixing the grain, the portion of the microbial liquid sprayed by the nozzle 9 that is not completely absorbed by the grain will seep into the bottom of the processing box 1 through the holes of the mesh cylinder 3 and collect. When the excess microbial liquid in the processing box 1 accumulates to a certain amount, the solenoid valve 29 is opened, so that the excess microbial liquid collected at the bottom of the processing box 1 is discharged through the drain pipe 28. After the appropriate amount is discharged, the solenoid valve 29 is closed to stop the drainage operation and avoid waste caused by the continuous discharge of microbial liquid. After processing, the solenoid valve 29 can be reopened to check for any residual bacterial solution at the bottom of the processing tank 1, ensuring that the residual bacterial solution is discharged smoothly. Then, the solenoid valve 29 is closed, and the drain pipe 28 and solenoid valve 29 are cleaned to prevent bacterial solution residue from clumping and clogging the pipes or affecting the control effect of the solenoid valve 29. This structure is easy to assemble. The solenoid valve 29 allows for flexible control of the timing and volume of drainage, while the drain pipe 28 promptly discharges excess bacterial solution, reducing its accumulation in the processing tank 1 and minimizing the impact of residual bacterial solution on subsequent processing quality. It is suitable for the overall requirements of bacterial agent spraying and mixing in the device.

[0035] In a further preferred embodiment of the present invention, a protective shell is fixed on the base plate 49. The protective shell is used to shield the motor 15 and the reducer 16. The protective shell is provided with a heat dissipation port for exhaust and heat dissipation.

[0036] In this embodiment, a protective shell is fixed on the base plate 49 to shield the motor 15 and the reducer 16. When the motor 15 and the reducer 16 are running, the heat generated is dissipated to the outside through the heat dissipation vents on the protective shell, continuously maintaining the heat dissipation state of the equipment operating environment. After the motor 15 starts, its output shaft drives the reducer 16 to run. The heat generated by the two accumulates inside the protective shell, so that the heat is discharged outward through the heat dissipation port, keeping the operating temperature of the motor 15 and the reducer 16 within a reasonable range.

[0037] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, the functional grain processing device further includes a dust collection mechanism for collecting dust and impurities. The dust collection mechanism includes: a collection box 40, a filter bag 41, a dust collection shell 43, a second rotating shaft 44, a fan blade 45, a third pulley 46, a fourth pulley 47, and a second transmission belt 48. The collection box 40 is fixed on the processing box 1. The filter bag 41 is disposed inside the collection box 40. The dust collection shell 43 is fixed on the top of the feed hopper 25 and is connected to the collection box 40 through a conduit 42. The second rotating shaft 44 is rotatably mounted inside the collection box 40 through a sealed bearing. The fan blade 45 is fixed on the second rotating shaft 44. The third pulley 46 and the fourth pulley 47 are respectively fixed on the spiral shaft 24 and the second rotating shaft 44. The second transmission belt 48 is sleeved on the third pulley 46 and the fourth pulley 47.

[0038] In this embodiment, when the grain is fed into the feed hopper 25, the fan blade 45 rotates to form an airflow, which causes the dust and impurities generated during the feeding process to be sucked into the dust collection shell 43, and then enters the collection box 40 through the conduit 42, and the dust is intercepted and retained by the filter bag 41. This device can collect dust and impurities during the feeding process, reducing the impact of dust diffusion on the processing environment; at the same time, it is powered by the screw shaft 24, eliminating the need for additional power components and improving the integration of the device; the filter bag 41 facilitates the subsequent treatment of the collected dust, improving ease of use.

[0039] In another embodiment of the present invention, a sealing plate 30 is slidably installed inside the feed hopper 25, and a connecting plate 31 is fixed to one end of the sealing plate 30. One end of the connecting plate 31 is fixedly connected to the assembly plate 33.

[0040] In this embodiment, when feeding is required, the electric telescopic rod 32 pushes the assembly plate 33 to move, causing the connecting plate 31 and the sealing plate 30 to slide, opening the channel of the feeding hopper 25; when feeding is not required, the electric telescopic rod 32 drives the assembly plate 33 to retract, so that the sealing plate 30 resets and closes the channel of the feeding hopper 25. The sealing plate 30 can open and close the feed hopper 25 channel in accordance with the feeding rhythm, reducing the possibility of external impurities entering the feed hopper 25; at the same time, its action is linked with the assembly plate 33, without the need for separate control, improving the linkage of device operation; in the closed state, it can reduce the spread of dust during processing and help maintain the cleanliness of the processing environment.

[0041] This invention also proposes a processing method for functional grains, the method comprising the following steps: Step 1: Equipment pretreatment. Start the electric telescopic rod 32 to move the assembly plate 33, spline rod 36 and connecting plate 31, so that the spline rod 36 is inserted into the first spline cylinder 34, and the connecting plate 31 moves the sealing plate 30 to open the feed hopper 25 channel; connect the bacterial liquid supply equipment to the rotary joint 14, and check each component to ensure normal operation. Step 2: Grain feeding and dust removal. Start motor 15, which drives transmission shaft 17 to rotate via reducer 16 and first bevel gear 18. Then, it drives spiral shaft 24 to rotate via second bevel gear 27, first rotating shaft 12, first pulley 37, second pulley 38, and first transmission belt 39. Grain is added to feed hopper 25 and fed into mesh cylinder 3 via spiral shaft 24 and feed pipe 22. The rotation of spiral shaft 24 drives second rotating shaft 44 and fan blade 45 to rotate via third pulley 46, fourth pulley 47, and second transmission belt 48. Dust collection shell 43, guide tube 42, collection box 40, and filter bag 41 collect dust and impurities during feeding simultaneously. After feeding is completed, turn off motor 15. Electric telescopic rod 32 retracts, driving spline rod 36 to reset and sealing plate 30 to close. Step 3: Spraying and stirring of microbial agent. Start the liquid supply equipment and motor 15. The microbial liquid is sprayed from the nozzle 9 through the rotary joint 14, the second channel 13, and the first channel 8. At the same time, the first rotating shaft 12 drives the stirring shaft 5, the connecting rod 6, and the stirring plate 7 to rotate through the spline seat 10 and the spline block 11, so as to achieve full mixing of grain and microbial liquid. Step 4: Drain excess bacterial solution. Open solenoid valve 29 in time to drain excess bacterial solution from the bottom of processing box 1 through drain pipe 28, and then close it. Step 5: Finishing the discharge process. Turn off the motor 15 and the liquid supply equipment. Start the electric hydraulic rod 20 to drive the connecting frame 21 and the second side plate 4 to separate. The pusher plate 19 moves with the stirring shaft 5 to push the processed grain to the discharge trough 26. After the process is completed, turn off the equipment and reset all components.

[0042] In summary, compared with related technologies, this solution integrates multiple functions such as feeding, dust removal, inoculation, stirring, liquid discharge, and material discharge through the coordinated operation of processing mechanisms, feeding mechanisms, microbial agent spraying mechanisms, discharging mechanisms, dust collection mechanisms, protective shells, and sealing plates, thereby reducing the risk of contamination. The linkage between the stirring shaft and the nozzles ensures uniform inoculation of the microbial solution, and excess microbial solution is promptly discharged through the drain pipe and solenoid valve. The mesh cylinder and stirring plate further reduce residue. Simultaneously, the protective shell ensures stable operation of the motor 15 and reducer 16, while the sealing plate and dust collection mechanism help maintain a clean processing environment, thus comprehensively improving the processing quality and efficiency of functional grains.
