Abstract
Description
Technical Field
[0001] This application belongs to the technical field of grain storage and transportation equipment, and in particular relates to a grain circulation and transfer conveying device with anti-caking function. Background Technology
[0002] Grain silos are common grain storage facilities, capable of storing at least several hundred tons of grain. They are equipped with ventilation and drying systems to enable long-term grain storage. However, grain within the silo also requires a transfer operation to move grain that has been under pressure at the bottom to the top, preventing clumping and other problems. The following issues arise during this transfer process:
[0003] 1. Currently, grain transfer is carried out entirely through the central grain outlet in the bottom silo. However, due to the long-term compression of grain on the inner wall of the bottom silo and the inner wall of the storage silo, clumps of grain may form. During the transfer, the flow of grain through the central grain outlet is not uniform. Instead, the grain that flows more easily in the center of the storage silo flows out first, resulting in the transfer effect still needing improvement.
[0004] 2. Conventional grain storage silos are five meters or more high, which can cause grain to break during the transfer process. In addition, the grain is distributed in an inverted cone shape inside the silo, and the grain at the bottom of the silo is subjected to more even pressure. During the transfer process, it is necessary to ensure that the grain is distributed in an inverted cone shape.
[0005] 3. The process of transferring grain requires the use of conveying devices and elevators. The bottom silo is not high above the ground, and the area and width of the conveyor belt are not very large. During the transfer process, it is necessary to ensure that the grain flows out stably and accurately aligned with the conveyor belt, reduce the falling speed of the grain, and prevent grain from spilling out. Summary of the Invention
[0006] In order to solve the above problems, this application provides a grain circulation and transfer conveying device with anti-caking function.
[0007] The purpose of this application is to provide a grain circulation and conveying device with anti-caking function. This application has a central grain outlet on the bottom silo and an edge grain outlet arranged on the side of the bottom silo. When the grain in the grain silo is transferred, the grain can flow out not only from the central grain outlet but also from the edge grain outlet. This avoids the grain that has been compressed for a long time on the inner wall of the bottom silo and the inner wall of the grain silo from not being able to flow out in time during the transfer. This ensures that the grain in the grain silo can be discharged relatively evenly and fully. Combined with the grain discharge assembly and other structures, this achieves the effects of precise transfer, reduced breakage, and anti-caking.
[0008] To achieve the purpose of this application, the technical solution of this application is as follows:
[0009] A grain circulation and conveying device with anti-caking function includes at least one grain storage silo. The lower end of the grain storage silo is a conical bottom silo. A central grain outlet is provided in the center of the bottom silo, and an edge grain outlet is provided on the side of the bottom silo. A grain dispensing assembly is provided on the edge grain outlet, and the grain dispensing assembly includes a bending section. A conveying device is provided below the bottom silo. The end of the grain dispensing assembly and the end of the central grain outlet are aligned with the conveying device. The end of the conveying device is connected to a hoist, and the end of the hoist is connected to the top of the grain storage silo through a grain pouring pipe.
[0010] Furthermore, a ring plate is provided around the outer periphery of the bottom silo. The grain dispensing assembly includes an upper connector, a lower connector, and a bent section fixedly connected to the upper and lower connectors. The bent section is a connecting pipe that can be bent and deformed. A connecting ring is provided on the lower connector, and a pull rod is hinged on the connecting ring. The top of the pull rod is connected to the ring plate. The upper end of the connecting pipe is connected to the upper connector, and the lower end of the connecting pipe is connected to the lower connector. The upper and lower connectors are fixedly connected to the connecting pipe through a fixing ring.
[0011] Furthermore, the upper end of the pull rod is provided with a threaded end, which passes through the regulator. The upper end of the regulator is provided with a hook, which is hung on the ring plate. The regulator includes a connecting plate with a through hole. The threaded end passes through the through hole. Nuts are arranged at both ends of the connecting plate. The nuts fix the threaded end to the regulator. The degree of bending of the connecting pipe is changed by changing the position of the nuts at the threaded end.
[0012] Furthermore, the upper connector includes an upper sleeve, which is vertically arranged, and contains several spiral guide plates evenly distributed around the central axis of the upper sleeve. The spiral guide plates are arranged in a spiral configuration. The lower connector includes a lower sleeve, which is inclined, and contains several straight guide plates evenly distributed around the central axis of the lower sleeve. The straight guide plates are straight plates.
[0013] Furthermore, a grain separator is installed inside the grain storage silo. The grain separator is arranged along the inner wall of the grain storage silo. The grain separator divides the grain outflow into two parts. A part of the grain in the grain storage silo flows along the inside of the grain separator to the edge grain outlet, and a part of the grain in the grain storage silo flows along the outside of the grain separator to the center grain outlet.
[0014] Furthermore, the grain separator includes a ring channel arranged in a ring along the inner wall of the grain storage silo. An inclined top plate is provided at the upper end of the ring channel, and several grain inlet pipes are provided on the inclined top plate. The grain inlet pipes are arranged at intervals along the inner wall of the grain storage silo. Several grain outlet pipes are provided at the lower end of the ring channel, and the grain outlet pipes are arranged at intervals along the inner wall of the bottom silo. The end of the grain outlet pipe is connected to the edge grain outlet. Several inclined inner plates are provided inside the ring channel. One end of the inclined inner plate is connected to the end of the grain inlet pipe, and the other end of the inclined inner plate is connected to the top of the grain outlet pipe.
[0015] Furthermore, a slow-descent assembly is installed inside the grain storage silo. The slow-descent assembly includes a feeder arranged at the top of the grain storage silo, which is equipped with several chutes. The chutes are suspended from the grain storage silo by a chain assembly. Several edge slow-descent devices are installed on the inner wall of the grain storage silo. The end of the chutes is aligned with the top of the edge slow-descent devices, and the end of the edge slow-descent devices is aligned with the top of the grain inlet pipe. The edge slow-descent devices include several vertically arranged slow-descent sections. Each slow-descent section includes an inclined upper slow-descent device and an inclined lower slow-descent device. The upper and lower slow-descent devices are arranged on the section body. The end of the upper slow-descent device is aligned with the top of the lower slow-descent device. The end of the upper slow-descent device has an opening, and the section body also has an opening.
[0016] Furthermore, a movable rocker is provided on the deceleration section located on the upper part of the edge decelerator. The movable rocker includes a rotating shaft and an inner baffle and an outer baffle arranged on the rotating shaft. The inner baffle is arranged between the upper decelerator and the lower decelerator of the deceleration section, and the outer baffle is arranged on the outside of the section body. By controlling the amount of grain falling, the outer baffle and the inner baffle are subjected to different impact forces from the grain, thereby causing the outer baffle to block the opening on the section body or the inner baffle to block the opening at the end of the upper decelerator.
[0017] Furthermore, the conveying device is configured to adjust the amount of grain conveyed by the conveying device to the elevator according to the grain conveying volume or time, or the elevator is configured to adjust the amount of grain conveyed by the elevator to the grain storage bin according to the grain conveying volume or time.
[0018] Furthermore, the front end of the conveying device is provided with a grain blocking assembly, which includes a support frame and a flexible grain blocking plate on the support frame. The top of the grain blocking plate is located on the support frame, and the end of the grain blocking plate is either in contact with or spaced from the conveyor belt of the conveying device.
[0019] Compared with the prior art, the beneficial effects of this application are as follows:
[0020] 1. This application features a central grain outlet on the bottom silo and edge grain outlets on the sides of the bottom silo. When the grain in the storage silo is transferred, the grain can flow out not only from the central grain outlet but also from the edge grain outlets. This prevents the grain from becoming compacted and unable to flow out in time during the transfer process, as this ensures that the grain in the storage silo can be discharged more evenly and fully. The grain enters the conveying device and then reaches the elevator, which pours the grain back into the original storage silo or a new storage silo, resulting in a better transfer effect.
[0021] 2. This application installs a grain discharge assembly on the edge grain outlet. The grain discharge assembly controls the speed, direction, and amount of grain flowing out of the edge grain outlet, achieving accurate guidance and reducing breakage. The grain discharge assembly of this application has a flexible connecting pipe in the middle. This application adjusts the bending degree of the connecting pipe by a pull rod, thereby changing the speed and amount of grain passing through the bend and ensuring that the grain discharge assembly is aligned with the conveying device. In addition, the upper connector of the grain discharge assembly of this application has a spiral guide plate. The grain inside the grain storage bin can flow along the spiral guide plate, thereby reducing the falling speed of the grain. Combined with the bent connecting pipe, it achieves the purpose of reducing breakage. The lower connector of the grain discharge assembly has a straight guide plate with a straight plate structure. The grain, after being decelerated, accurately reaches the conveying device along the straight guide plate, avoiding grain spillage. The grain flows out accurately and stably throughout the entire process.
[0022] 3. The upper section of the pull rod in this application is a threaded end, which is arranged inside the adjuster. The nut is engaged with the threaded end. By adjusting the position of the nut at the threaded end, the length of the pull rod inside the adjuster changes, thereby changing the degree of bending of the connecting pipe. Because the nut is engaged with the threaded end, the degree of bending of the connecting pipe can be precisely adjusted, making it highly adaptable. Especially when the space below the silo is small and the size of the conveying device is small, the grain discharge assembly can accurately deliver the grain to the conveying device.
[0023] 4. This application uses a grain separator to divide the grain near the bottom silo into two parts, so that the grain inside the separator flows out from the edge outlet and the grain outside the separator flows out from the center outlet, thus avoiding the grain flowing in the bottom silo from affecting each other and causing unstable grain flow from the center outlet and the edge outlet.
[0024] 5. This application includes a slow-fall assembly for reducing breakage inside the grain storage silo. The slow-fall assembly includes an edge slow-fall device arranged on the inner wall of the grain storage silo and a chute aligned with the edge slow-fall device. Grain reaches the edge slow-fall device along the chute. Under the action of the edge slow-fall device, the falling speed of the grain is reduced, preventing the grain from breaking when falling from a height. In addition, the edge slow-fall device changes the distribution of the grain, making the distribution of the grain more in line with the shape of the bottom silo. It plans the amount and speed of grain output from the central grain outlet and the edge grain outlet, ensuring that the grain can fall accurately and stably onto the conveying device.
[0025] 6. The deceleration section located at the lower part of the edge decelerator allows grain to flow from the opening on the section to the outside of the grain separator, or it can flow step by step into the inside of the grain separator along the opening on the lower decelerator. The deceleration section located at the upper part of the edge decelerator is equipped with a movable rocker. In the early stage of grain transfer, the amount of grain falling is controlled so that the outer baffle blocks the opening on the section, preventing the grain from falling directly from a height without the action of the deceleration section. In the later stage of grain transfer, the amount of grain falling is controlled so that the inner baffle blocks the opening at the end of the upper decelerator, allowing the grain to flow out from the opening on the section, preventing excessive grain from being stored in the deceleration section.

[0042] Example 1
[0043] This embodiment is a grain storage or storage device with a transfer function. It is a grain circulation transfer and conveying device with anti-caking function. While realizing storage, it can also achieve the purpose of transfer. During the transfer, it can also reduce breakage and change the grain distribution line in the storage. By pouring the grain in the grain storage silo 1 out of the silo and then pouring it back to the original grain storage silo 1 or a new grain storage silo 1 through the conveying device 3 and the elevator 4, the position of the grain is changed, avoiding problems such as caking caused by long-term grain storage.
[0044] As a main component, this application includes at least one grain storage silo 1. For example, in this embodiment, there is one grain storage silo 1. The lower end of the grain storage silo 1 is a conical bottom silo. A conveyor device 3 is placed below the bottom silo. For example, the conveyor device 3 used in this embodiment is a belt conveyor device 3. The end of the conveyor device 3 is connected to an elevator 4. The end of the elevator 4 is connected to the top of the grain storage silo 1 through a grain discharge pipe 7. As a key inventive feature, a central grain outlet is provided in the center of the bottom silo, and an edge grain outlet is provided on the side of the bottom silo. The grain outlet of the bottom silo is no longer limited to the center outlet, but is combined with the edge outlet. The edge outlet is equipped with a grain outlet assembly 2, which includes a bending section. The bending section allows the grain outlet assembly 2 to bend, so that the end of the grain outlet assembly 2 can be aligned with the conveying device 3. In addition, the end of the center outlet is also aligned with the conveying device 3. In use, the conveying device 3 is placed with the center outlet as the reference, and the grain outlet assembly 2 is adjusted to allow the grain to reach the conveying device 3 from the center outlet and the edge outlet.
[0045] As a specific implementation scheme, this embodiment has a grain blocking assembly 5 installed at the front end of the conveying device 3. The grain blocking assembly 5 includes a support frame, which is fixed on the conveying device 3. A flexible grain blocking plate is installed on the support frame. For example, the grain blocking plate is made of flexible rubber. The top of the grain blocking plate is fixed to the support frame by bolts. The end of the grain blocking plate abuts against or is spaced apart from the conveyor belt of the conveying device 3. When the grain reaches the conveyor belt of the conveying device 3 from the edge grain outlet and the center grain outlet, the grain blocking plate can block the grain, so that the grain smoothly enters the elevator 4 along the transmission belt of the conveying device 3.
[0046] As the installation structure for the central grain outlet, this embodiment can install a sealing plate on the flange of the central grain outlet. When grain needs to be discharged, the sealing plate can be removed to achieve grain discharge. As the installation structure for the edge grain outlet, this embodiment uses a grain discharge assembly 2. As a specific implementation scheme, this embodiment can directly use a bent steel pipe or plastic pipe as the grain discharge assembly 2. However, due to the lack of an adjustment structure, it is impossible to control and adjust the grain discharge amount, discharge speed, and discharge direction. As another specific implementation scheme, the grain discharge assembly 2 in this embodiment includes an upper connector 9, a lower connector 10, and a bent section fixedly connected to the upper connector 9 and the lower connector 10. For example, the upper connector 9 has a flange. The flange is fitted with a sleeve to allow for a detachable connection between the upper connector 9 and the edge grain outlet. The lower connector 10 uses a straight sleeve. In this embodiment, the bent section is a bendable connecting pipe 11. The connecting pipe 11 is fixedly connected to the upper connector 9 and the lower connector 10 by a retaining ring 12. The retaining ring 12 can be a clamp structure or two arc-shaped plates connected together by bolts. A connecting ring 13 is installed on the lower connector 10. For example, in this embodiment, the connecting ring 13 is two arc-shaped plates connected together by bolts. One arc-shaped plate has a hinge seat. A tie rod 14 is hinged on the connecting ring 13, and the hinge position is on the hinge seat.
[0047] This embodiment adjusts the grain discharge direction and other parameters by adjusting the bending degree of the connecting pipe 11. As a specific implementation, a ring plate 6 is installed around the outer periphery of the silo. Through holes are formed on the ring plate 6 along the height direction. The hook 16 at the upper end of the pull rod 14 is hung on the through holes above the ring plate 6. The bending angle of the connecting pipe 11 is changed by varying the position of the hanging through holes. As another specific implementation, this embodiment offers a superior adjustment scheme with more selectable bending angles for the connecting pipe 11. The upper end of the pull rod 14 in this embodiment has a threaded end that passes through the adjuster 15. A hook 16 is installed at the upper end of the adjuster 15 and hangs on the ring plate 6. The adjuster 15 includes a connecting plate with through holes. The threaded end passes through the through holes, and nuts are arranged at both ends of the connecting plate. The nuts fix the threaded end to the adjuster 15. The bending degree of the connecting pipe 11 is changed by varying the position of the nuts at the threaded end.
[0048] This embodiment also addresses the potential breakage issues caused by high-speed descent during grain flow and the grain scattering and spillage issues resulting from the uncertain trajectory of the grain. As a specific implementation plan, the upper connector 9 includes an upper sleeve arranged vertically. Several spiral guide plates 17 are installed inside the upper sleeve; for example, in this embodiment, there are four spiral guide plates 17 arranged spirally, evenly distributed around the central axis of the upper sleeve. The lower connector 10 includes a lower sleeve. Due to the bending of the connecting pipe 11, the lower sleeve is arranged at an angle. Several straight guide plates 18 are installed inside the lower sleeve; for example, in this embodiment… In this embodiment, there are 3-6 straight guide plates 18. The straight guide plates 18 are a type of straight plate structure. These straight guide plates 18 are evenly distributed around the central axis of the lower sleeve. When the grain reaches the grain discharge assembly 2 from the edge grain outlet, the grain can flow along the spiral guide plate 17, thereby reducing the falling speed of the grain. In conjunction with the bent connecting pipe 11, the purpose of reducing breakage is achieved. Due to the reduced falling speed of the grain, the lower connector 10 of the grain discharge assembly 2 has a straight guide plate 18 with a straight plate structure. The grain that has been decelerated reaches the conveying device 3 stably and accurately along the straight guide plate 18, avoiding grain overflow. The grain flows out accurately and stably throughout the process.
[0049] As a structure that works in conjunction with the edge and center grain outlets, to prevent the grain from interfering with each other, for example, the grain in the center of the grain storage silo 1 is less compressed, looser, and more fluid, while the grain on the bottom wall and inner wall of the grain storage silo 1 is compressed over a long period of time, which may result in clumps. The flow of grain from different outlets is not uniform. Therefore, this embodiment uses a grain separator 8 to divide the grain to be discharged from the grain storage silo 1 into two parts. Specifically, the grain separator 8 is arranged along the inner wall of the grain storage silo 1. The grain separator 8 can divide the grain flow into two parts: one part of the grain in the grain storage silo 1 flows along the inside of the grain separator 8 to the edge grain outlet, and another part flows along the outside of the grain separator 8 to the center grain outlet. As a more specific implementation, the grain separator 8 includes a ring channel 19, which is arranged in a ring along the inner wall of the grain storage silo 1. The upper end of the ring channel 19 has an inclined top plate. Several grain inlet pipes 21 are installed on the sloping top plate, and the grain inlet pipes 21 are arranged at intervals along the inner wall of the grain storage silo 1. Several grain outlet pipes 20 are installed at the lower end of the ring channel 19, and the grain outlet pipes 20 are arranged at intervals along the inner wall of the bottom silo. The end of the grain outlet pipe 20 is connected to the edge grain outlet. Several inclined inner plates are installed inside the ring channel 19. One end of the inclined inner plate is connected to the end of the grain inlet pipe 21, and the other end of the inclined inner plate is connected to the top of the grain outlet pipe 20. In this embodiment, the grain separator 8 has a frame-type support structure, which avoids the grain from being pressed against the inner wall of the bottom silo. In addition, since the grain is divided into two parts, the overall pressure is also greatly reduced, the grain flow is good, and the grain clumping can be avoided as much as possible. The grain separator 8 also has a certain grain storage function. The grain inside the grain separator 8 moves along the inside of the grain separator 8 to the edge grain outlet, and the grain outside the grain separator 8 moves along the outside of the grain separator 8 and the bottom silo to the center grain outlet. The two have low mutual interference, good flow, and better grain transfer effect.
[0050] As a specific implementation scheme, in the grain separator 8 of this embodiment, there are multiple connection schemes for the grain inlet pipe 21, the grain outlet pipe 20 and the ring channel 19. For example, in this embodiment, the grain inlet pipe 21 and the grain outlet pipe 20 are fixedly connected by bolts, or they can be fixedly connected by riveting, welding and other methods. Another scheme is that the grain inlet pipe 21, the grain outlet pipe 20 and the ring channel 19 all have sheet metal structures. By bending the sheet metal and rolling it together, a snap-fit connection is achieved. That is, a piece of sheet metal is bent into a U-shaped structure, and the matching sheet metal is also bent into a U-shaped structure. The two U-shaped structures are snapped together to achieve the purpose of connection.
[0051] Conventional grain storage silos 1 are relatively tall, especially most grain storage silos 1, which are over five meters high. Therefore, during grain transfer, especially from old grain storage silos 1 to new grain storage silos 1, the huge height difference can cause severe grain breakage. Therefore, in this embodiment, a slow-descent assembly is arranged inside the grain storage silo 1. Since the grain storage silo 1 in this embodiment has a conical bottom structure, in order to avoid clumping, ensure good grain flow, and maintain a nearly uniform grain height line, this embodiment also requires an inverted conical grain stacking line 28. As a specific implementation plan, the slow-descent assembly includes a feeder arranged at the top of the grain storage silo 1, and the feeder is equipped with several chutes 22. For example, in this embodiment, there are 4-6 chutes 22. The chutes 22 are suspended from the top of the grain storage bin 1 by the chain assembly 23. The feeder protrudes from the top of the grain storage bin 1 and is connected to the grain pouring pipe 7 on the elevator 4 by a pipe. Several edge decelerators 25 are installed on the inner wall of the grain storage bin 1. The number of edge decelerators 25 is the same as the number of chutes 22. The end of the chutes 22 is aligned with the top of the edge decelerators 25. The end of the edge decelerators 25 is aligned with the top of the grain inlet pipe 21 of the grain separator 8. In this embodiment, the grain enters the chutes 22 from the feeder and enters the edge decelerators 25 along the end of the chutes 22.
[0052] The edge decelerator 25 of this embodiment includes several vertically arranged deceleration sections 24. As a unified structure of the deceleration sections 24, the deceleration section 24 includes a section body 29 and an inclined upper decelerator 26 and an inclined lower decelerator 27. The upper decelerator 26 and the lower decelerator 27 are mounted on the section body 29. The end of the upper decelerator 26 is aligned with the top of the lower decelerator 27. The end of the upper decelerator 26 has an opening. The section body 29 has an opening. As a specific implementation, the upper decelerator 26 is formed by welding two side plates together with an inclined bottom plate. The lower decelerator 27 is formed by welding two side plates together with an inclined bottom plate. The opening is located at the end of the bottom plate. In terms of the arrangement of the upper decelerator 26 and the lower decelerator 27, the upper decelerator 26 and the lower decelerator 27 are combined to form a "V" shaped structure, rather than the upper decelerator 26 and the lower decelerator 27 having parallel bottom plates.
[0053] In one implementation scheme, the openings on the lower or lower-middle section of the edge decelerator 25, as well as the openings on the upper decelerator 26 and lower decelerator 27, are all in an open state. However, the opening on the deceleration section 24 in the upper section of the edge decelerator 25 is in a semi-open state. This is mainly to prevent the grain from falling directly from the opening on the section 29 of the deceleration section 24 in the upper section of the edge decelerator 25 and causing breakage. Furthermore, since the edge decelerator 25 can also store a certain amount of grain, this embodiment also needs to ensure an appropriate amount of grain inside the edge decelerator 25. As a more specific implementation, this embodiment has a movable rocker 30 installed on the deceleration section 24 of the upper segment of the edge decelerator 25. The movable rocker 30 blocks the opening on the upper buffer or the opening on the section body 29. As a specific structure, the movable rocker 30 in this embodiment includes a rotating shaft and an inner baffle and an outer baffle arranged on the rotating shaft. The inner baffle is arranged between the upper decelerator 26 and the lower decelerator 27 of the deceleration section 24, and the outer baffle is arranged on the outside of the section body 29. In terms of gravity configuration, the inner baffle is slightly heavier than the outer baffle, so that the outer baffle can block the section under normal conditions. The opening on section 29 controls the amount of grain falling, causing the outer and inner baffles to experience different impact forces from the grain. This results in the outer baffle blocking the opening on section 29, or the inner baffle blocking the opening at the end of the upper buffer 26. When the grain is initially delivered into the grain storage bin 1, the grain delivery rate is small, and the outer baffle can block the opening on section 29. As the amount of grain in the grain storage bin 1 gradually increases, the grain delivery rate increases, and more grain impacts the outer baffle, causing it to open. The inner baffle then blocks the opening on the upper buffer, preventing excessive grain storage in the edge buffer and ensuring that the grain flows smoothly along the edge. The opening on section 29 flows into the interior of grain storage silo 1, and the grain stacking line 28 is inverted cone shape, ensuring that the endpoints of the top grain at multiple locations are close to the lowest point of the grain on the same vertical line. This reduces the problem of grain clumping caused by uneven compression of grain on the inner wall of the bottom silo and some areas of the inner wall of grain storage silo 1 over a long period of time. Furthermore, this structure in this embodiment can avoid the use of electronic components and other electrical equipment in grain storage silo 1, which not only reduces the cost of use and equipment, but also avoids the impact of grain on electronic components and the safety hazards caused by broken circuits and disconnected connectors of electronic components.
[0054] It should be noted that the outer baffle does not need to block the opening on the section 29. It only needs to be at a certain angle so that the grain cannot pass smoothly through the opening on the section 29 but can only pass through the opening on the upper decelerator 26.
[0055] In the final stage of grain transfer, the grain outlet on chute 22 can be opened to allow the grain to flow towards the stacking line.
[0056] As a more specific implementation, ventilation holes are provided on the grain separator 8 and the edge decelerator 25 in this embodiment. This embodiment can ensure the stable storage of grain in the grain storage silo 1 by injecting dry and cold air into the grain storage silo 1.
[0057] As a detailed description of the conveying device 3, the conveying device 3 in this embodiment adopts a belt conveyor. The power input of the conveying device 3 is driven by a motor. It is configured to adjust the amount of grain conveyed by the conveying device 3 to the elevator 4 according to the amount of grain conveyed or the time. The adjustment method is to control the speed of the motor. The output shaft of the motor can be connected to the input shaft of the conveying device 3 through a reducer to prevent the conveying device 3 from rotating too fast. In addition, a belt scale can be installed between the conveying device 3 and the elevator 4 to weigh the amount of grain conveyed to the elevator 4. The controller can determine the amount of grain to be transferred to the storage bin based on the grain quality measured by the belt scale and the conveying time, and then control the grain conveying speed and change the amount of grain conveyed. Similarly, this embodiment can also change the lifting speed of the elevator 4. The power input of the elevator 4 is also a motor. A belt scale can be installed between the conveying device 3 and the elevator 4. The elevator 4 is configured to adjust the amount of grain conveyed by the elevator 4 to the grain storage bin 1 according to the amount of grain conveyed or the time.
[0058] As another implementation, this embodiment can also save costs by manually adjusting the power of the conveying device 3 and the elevator 4 using experience and time.
[0059] Example 2
[0060] This embodiment is based on embodiment 1. In this embodiment, there are two grain storage silos 1 and one elevator 4. The elevator 4 is placed between the two grain storage silos 1, and a conveying device 3 is placed between each grain storage silo 1 and the elevator 4.
[0061] It should be noted that if one grain storage silo 1 is used for grain transfer, that is, the grain in the original grain storage silo 1 is poured back into the original grain storage silo 1, the grain originally located in the bottom silo will still be in the bottom silo after the transfer is completed. Therefore, this embodiment can use two grain storage silos 1 as the basis, one grain storage silo 1 containing grain and the other grain storage silo 1 not containing grain. The grain in the grain storage silo 1 containing grain is transferred to the grain storage silo 1 without grain. As a detailed process description, this embodiment first pours about half of the grain in the original grain storage silo 1 back into the original grain storage silo 1, and then pours all the grain into the new grain storage silo 1 to realize the grain transfer. After the transfer is completed, the original grain storage silo 1 can also be inspected.
[0062] If both grain storage bins 1 contain grain and there are no extra grain storage bins 1, referred to here as bin A and bin B, a small amount of grain is poured from bin A into bin B, and a small amount of grain is poured from bin B into bin A. The process of pouring grain continues until half or all of the grain in bins A and B has been poured out. After the grain has been stored for a period of time, the process of pouring grain into bins can be considered again.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
[0064] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
