Description

Technical Field

[0001] The present application relates to the technical field of grain storage, and in particular to a metering and loading system for grain storage. Background Art

[0002] In the process of grain storage, the bulk grain is first transported by trucks and unloaded onto the storage belt conveyor. The storage belt conveyor transports the bulk grain to the bucket elevator. The bucket elevator lifts the bulk grain to the top of the granary and unloads the bulk grain onto the silo loading belt conveyor. The silo loading belt conveyor transports the bulk grain into each granary to realize the grain storage.

[0003] When grain is put into storage, the filling of the granary is usually controlled manually. When the granary is full, the loading channel of the granary is closed manually, and the loading belt conveyor then transports the bulk grain to other granaries. The manual control of the closing of the granary loading channel can easily cause the granary to be underloaded or overloaded due to human factors, resulting in poor accuracy of grain loading into the granary. Summary of the invention

[0004] In order to improve the accuracy of loading grain into a granary, the present application provides a metering and loading system for grain storage.

[0005] The present application provides a grain storage metering and loading system, which adopts the following technical solution: A metering and loading system for grain storage, comprising: Warehouse supervisor, for admitting bulk grain; There are multiple storage branch pipes, which correspond to the granaries one by one. The multiple storage branch pipes are arranged along the circumference of the storage main pipe. One end of the storage branch pipe is connected to the side wall of the storage main pipe, and the other end is connected to the corresponding granary. The guide cylinder is rotatably arranged in the storage main pipe, the top of the guide cylinder is used to receive the bulk grain, the bottom of the guide cylinder is provided with a closing plate, the closing plate closes the bottom of the guide cylinder, and the side wall of the guide cylinder is provided with a storage hole, which is used to communicate with any storage branch pipe; The control components are provided in multiple groups and correspond to the granaries one by one. The control components include a metering hose, a control box, a control slide plate, a control telescopic rod, a control spring and a return spring; in, The metering hose is connected to the inner wall of the granary, one end of the metering hose is arranged near the bottom end of the granary and is sealed, and the other end of the metering hose is arranged near the top end of the granary; The control box is connected to the side wall of the storage main pipe, the control slide is slidably arranged in the control box, a control cavity is formed between one side of the control slide and the control box, the control cavity is arranged close to the storage main pipe, the control cavity is connected to one end of the metering hose close to the top of the granary, and a fluid medium flows in the control cavity; The fixed end of the control telescopic rod is connected to the side of the control slide plate close to the control cavity and is slidably arranged on the control box. The movable end of the control telescopic rod is slidably arranged on the side wall of the storage main pipe. The control spring is arranged in the rodless cavity of the control telescopic rod and is used to drive the control telescopic rod to fully extend. A return spring is arranged on the side of the control slide away from the control chamber, and is used to drive the control slide to slide in the direction close to the storage main pipe. A control groove is opened on the material guide cylinder, and the control groove is used to clamp the movable end of any control telescopic rod. When the movable end of the control telescopic rod is clamped in the control groove, the storage hole is connected with the storage branch pipe corresponding to the control telescopic rod.

[0006] By adopting the above technical scheme, since the grain in the granary is not full, the metering hose is only partially squeezed, and the reset spring can drive the control slide plate to elastically squeeze the movable end of the control telescopic rod on the outer wall of the guide barrel. The bulk grain entering the warehouse first flows into the warehouse entry main pipe, and then flows into the guide barrel. Under the closing action of the closing plate, the bulk grain is discharged from the guide barrel from the warehouse entry hole of the guide barrel, and the guide barrel is rotated until the control groove on the guide barrel is aligned with the movable end of the control telescopic rod corresponding to the granary. The movable end of the control telescopic rod is clamped in the control groove under the elastic force of the control spring to fix the guide barrel and the warehouse entry main pipe, and also locate the warehouse entry hole and the warehouse entry branch pipe so that the warehouse entry hole is aligned with the warehouse entry branch pipe, and the bulk grain in the guide barrel flows from the warehouse entry hole into the warehouse entry branch pipe, and flows from the warehouse entry branch pipe into the granary to fill the granary.

[0007] The bulk grain is gradually loaded into the granary, so that the material level of the bulk grain in the granary gradually increases. When the granary is full of grain, the grain squeezes the metering hose as a whole, so that the hydraulic oil in the metering hose can all flow into the control cavity, so as to drive the control slide plate to slide in the direction away from the storage main pipe. The control slide plate drives the control telescopic rod to move. Before the granary is not full, the active end of the control telescopic rod can always keep the storage hole and the storage branch pipe connected with the elastic force of the control spring. After the granary is fully loaded, the control slide plate drives the active end of the control telescopic rod to disengage from the control groove. At this time, the control telescopic rod is in a fully extended state.

[0008] After the movable end of the control telescopic rod escapes from the control slot, the material guide barrel can continue to rotate until the movable end of the control telescopic rod corresponding to the next unfull granary is clamped in the control slot of the material guide barrel to fill the next unfull granary, thereby allowing multiple granaries to be loaded one by one, and after the granary is full, the next granary can be automatically switched for loading, making it less likely for the granary to be underloaded or overloaded, thereby improving the accuracy of loading and warehousing into the granary.

The magnetic ring can drive the material guide barrel to rotate, so that the material guide barrel can drive the entry hole to face the entry branch pipe; when the movable end of the control telescopic rod is clamped in the control groove, the driving force between the magnetic disk and the magnetic ring is a non-contact force, so that the magnetic disk can still rotate, and the motor is not easily damaged due to the fixation of the material guide barrel relative to the entry branch pipe.

[0011] Optionally, a travel switch is provided on the side of the control slide away from the control chamber, the travel switch is connected to the inner wall of the control box and is used to output a position signal, the travel switch is electrically connected to a first controller, the first controller is electrically connected to an electric gate, the electric gate is provided at the connection between the entry branch pipe and the entry main pipe, when the granary is fully loaded, the control slide is squeezed on the travel switch, the first controller responds to the position signal, and is used to control the electric gate to close, when the granary is underloaded, the control slide is separated from the travel switch, the first controller responds to the position signal, and is used to control the electric gate to open.

[0012] By adopting the above technical scheme, since the entry hole is connected to each entry branch one by one, when there is a fully loaded granary between two underloaded granaries, the disk drive magnetic ring can make the entry hole rotate to the entry branch corresponding to the fully loaded granary, so that the fully loaded granary can continue to be filled when it is fully loaded. Therefore, when the granary is full, the position signal output by the travel switch can be used to feedback its own full load situation. The first controller can control the closing of the electric gate corresponding to the granary according to the position signal to prevent the situation of continuing filling when it is fully loaded, thereby further improving the stability of granary loading.

One end of the metering rod is connected to the side of the control slide away from the control cavity, and the metering rod is slidably arranged on the control box. The displacement sensor is connected to the warehouse entrance main pipe and is arranged opposite to the end of the metering rod away from the control box. The displacement sensor is used to output a displacement signal. The chute scale and all the displacement sensors are electrically connected to a second controller. The second controller is electrically connected to a display. The second controller responds to the weight signal and is used to control the display to display the weight value of the warehoused grain.

Under the control of the second controller, the weight value of the grain entering the granary can be displayed on the display, so that the user can know the weight of the grain entering the granary, thereby making it convenient for the user to manage the grain entering the warehouse and the grain entering the granary.

[0032] Reference Figure 1 The main inlet pipe 1 is used to let in bulk grain. There are multiple branch inlet pipes 2, which correspond to the granaries one by one. The multiple branch inlet pipes 2 are evenly arranged along the circumference of the main inlet pipe 1. One end of the branch inlet pipe 2 is connected to the side wall of the main inlet pipe 1, and the other end is connected to the top of the corresponding granary.

[0033] Reference Figure 2 The guide cylinder 3 is rotatably arranged in the main inlet pipe 1. The top of the guide cylinder 3 is used to receive the bulk grain. The bottom of the guide cylinder 3 is provided with a closing plate 31. The closing plate 31 closes the bottom of the guide cylinder 3. The side wall of the guide cylinder 3 is provided with an inlet hole 32. The inlet hole 32 is used to communicate with any one of the inlet branch pipes 2 to guide the bulk grain into the connected inlet branch pipes 2.

[0034] A rotating ring is fixedly connected to the material guide cylinder 3 , a rotating groove is provided on the storage main pipe 1 , the rotating ring is rotatably arranged in the rotating groove, and the rotating ring and the rotating groove form a rotating connection structure of the material guide cylinder 3 and the storage main pipe 1 .

[0035] Reference Figure 2 , Figure 3 and Figure 4 There are multiple control components 4, which correspond to the granaries one by one. The control components 4 include a metering hose 41, a control box 42, a control slide plate 43, a control telescopic rod 44, a control spring 45 and a return spring 46.

[0036] Reference Figure 3 The metering hose 41 is vertically fixed to the inner wall of the granary, one end of the metering hose 41 is arranged near the bottom of the granary and is sealed, and the other end of the metering hose 41 is arranged near the top of the granary. The filling situation of the bulk grain in the granary can be fed back through the situation of the metering hose 41 being squeezed by the grain.

[0037] Reference Figure 3 and Figure 4 , the control box 42 is fixedly connected to the side wall of the storage main pipe 1. The control slide 43 is slidably arranged in the control box 42, and the sliding direction of the control slide 43 is the direction close to or away from the storage main pipe 1. A control cavity 431 is formed between one side of the control slide 43 and the control box 42. The control cavity 431 is arranged close to the storage main pipe 1. The end of the control cavity 431 close to the storage main pipe 1 is connected to the end of the metering hose 41 close to the top of the granary, and a fluid medium flows between the control cavity 431 and the metering hose 41. In the present application, the fluid medium is hydraulic oil. In the process of gradually loading bulk grain into the granary, the part of the bulk grain squeezing the metering hose 41 can gradually increase, so that the hydraulic oil in the metering hose 41 can flow into the control cavity 431 to drive the control slide 43 to slide, so that the sliding stroke of the control slide 43 can feedback the filling situation of the bulk grain in the granary.

[0038] Reference Figure 4 The fixed end of the control telescopic rod 44 is fixedly connected to the side of the control slide plate 43 close to the control cavity 431, the fixed end of the control telescopic rod 44 is slidably penetrated on the control box 42, and the movable end of the control telescopic rod 44 is slidably penetrated on the side wall of the storage main pipe 1. The control spring 45 is arranged in the rodless cavity of the control telescopic rod 44, and the two ends of the control spring 45 are respectively fixedly connected to the fixed end and the movable end of the control telescopic rod 44, and the control spring 45 is used to drive the control telescopic rod 44 to fully extend.

[0039] The return spring 46 is arranged on the side of the control slide 43 away from the control cavity 431. One end of the return spring 46 is fixedly connected to the control slide 43, and the other end is fixedly connected to the control box 42. The return spring 46 is used to drive the control slide 43 to slide in the direction close to the storage main pipe 1. The guide cylinder 3 is provided with a control groove 33, and the control groove 33 is used to clamp the movable end of any control telescopic rod 44. When the movable end of the control telescopic rod 44 is clamped in the control groove 33, the storage hole 32 is connected to the storage branch pipe 2 corresponding to the control telescopic rod 44. By clamping the movable end of the control telescopic rod 44 in the control groove 33, the storage hole 32 and the storage branch pipe 2 can be accurately positioned, so that the bulk grain can easily and accurately flow into the storage branch pipe 2.

[0040] When in use, since the grain in the granary is not full, the metering hose 41 is only partially squeezed, and the return spring 46 can drive the control slide plate 43 to make the movable end of the control telescopic rod 44 elastically squeezed on the outer wall of the guide cylinder 3, and the bulk grain entering the warehouse first flows into the warehouse main pipe 1, and then flows into the guide cylinder 3. Under the closing action of the closing plate 31, the bulk grain is discharged from the guide cylinder 3 from the warehouse entry hole 32 of the guide cylinder 3, and the guide cylinder 3 is rotated until the control groove 33 on the guide cylinder 3 is aligned with the movable end of the control telescopic rod 44 corresponding to the granary, and the movable end of the control telescopic rod 44 is clamped in the control groove 33 under the elastic force of the control spring 45 to fix the guide cylinder 3 and the warehouse main pipe 1, and also position the warehouse hole 32 and the warehouse branch pipe 2, so that the warehouse hole 32 is aligned with the warehouse branch pipe 2, and the bulk grain in the guide cylinder 3 flows from the warehouse hole 32 into the warehouse branch pipe 2, and flows into the granary from the warehouse branch pipe 2 to fill the granary.

[0041] The bulk grain gradually fills the granary, so that the material level of the bulk grain in the granary gradually increases. When the granary is full of grain, the grain squeezes the metering hose 41 as a whole, so that the hydraulic oil in the metering hose 41 can all flow into the control cavity 431, so as to drive the control slide plate 43 to slide in the direction away from the storage main pipe 1, and the control slide plate 43 drives the control telescopic rod 44 to move. Before the granary is not full, the movable end of the control telescopic rod 44 can always keep the storage hole 32 connected with the storage branch pipe 2 with the help of the elastic force of the control spring 45. After the granary is fully loaded, the control slide plate 43 drives the movable end of the control telescopic rod 44 to disengage from the control groove 33, and the control telescopic rod 44 is in a fully extended state.

[0042] After the movable end of the control telescopic rod 44 escapes from the control groove 33, the material guide cylinder 3 can continue to rotate until the movable end of the control telescopic rod 44 corresponding to the next unfull granary is clamped in the control groove 33 of the material guide cylinder 3 to fill the next unfull granary, thereby allowing multiple granaries to be loaded one by one, and after the granary is full, the next granary can be automatically switched for filling, making it less likely for the granary to be underloaded or overloaded, thereby improving the accuracy of loading grain into the granary.

The magnetic ring 34 can drive the material guide barrel 3 to rotate, so that the material guide barrel 3 can drive the entry hole 32 to face the entry branch pipe 2; when the movable end of the control telescopic rod 44 is clamped in the control groove 33, the driving force between the magnetic disk 12 and the magnetic ring 34 is a non-contact force, so that the magnetic disk 12 can still rotate, so that the motor 11 is not easily damaged due to the fixation of the material guide barrel 3 relative to the entry main pipe 1.

The travel switch 47 is electrically connected to a first controller 48, and the first controller 48 is fixedly connected to a control seat provided on the ground. The first controller 48 is electrically connected to an electric gate 49, and the electric gate 49 is provided at the connection point between the storage branch pipe 2 and the storage main pipe 1. When the granary is fully loaded, the control slide 43 is pressed on the travel switch 47, and the first controller 48 responds to the position signal and is used to control the electric gate 49 to close. When the granary is underloaded, the control slide 43 is separated from the travel switch 47, and the first controller 48 responds to the position signal and is used to control the electric gate 49 to open.

[0046] Since the entry hole 32 is connected to each entry branch 2 one by one, when there is a fully loaded granary between two underloaded granaries, the magnetic disk 12 drives the magnetic ring 34 to make the entry hole 32 rotate past the entry branch 2 corresponding to the fully loaded granary, so that the fully loaded granary can continue to be filled when it is fully loaded. Therefore, when the granary is full, the position signal output by the travel switch 47 can feedback its own full load situation, and the first controller 48 can control the electric gate 49 corresponding to the granary to close according to the position signal, so as to prevent the granary from continuing to be filled when it is fully loaded, thereby further improving the stability of granary loading.

[0047] Reference Figure 1 and Figure 4In order to accurately measure the grain entering the warehouse and the grain entering the granary, so as to facilitate the management of grain entering the warehouse, a grain entering the warehouse metering and loading system also includes a metering component 5, which includes a chute scale 51, a metering rod 52 and a displacement sensor 53. The chute scale 51 is connected to the feed end of the warehouse entrance main 1, and is used to output the weight signal of the grain entering the warehouse, and accurately measure the weight of the grain entering and leaving the warehouse in a mobile weighing manner; there are multiple metering rods 52 and displacement sensors 53, and they correspond one to one. The metering rod 52 corresponds one to one with the control slide 43, and one end of the metering rod 52 is fixedly connected to the side of the control slide 43 away from the control cavity 431. The metering rod 52 is slidably penetrated on the control box 42, and the movement displacement of the metering rod 52 can directly feedback the grain loading situation in the granary.

[0048] The displacement sensor 53 is connected to the storage main pipe 1 and is arranged opposite to the end of the metering rod 52 away from the control box 42. The displacement sensor 53 is used to output a displacement signal. The chute scale 51 and all the displacement sensors 53 are electrically connected to a second controller 54. The second controller 54 is fixedly connected to a control seat on the ground. The second controller 54 is electrically connected to a display 55. The display 55 is fixedly connected to the control seat on the ground. The second controller 54 responds to the weight signal and is used to control the display 55 to display the weight value of the stored grain. The second controller 54 responds to the displacement signal and is used to control the display 55 to display the weight value of the stored grain.

[0049] Before the grain flows into the warehouse main pipe 1, all the grain will flow through the chute scale 51, which will measure the grain entering the warehouse and output a weight signal. Under the control of the second controller 54, the weight value of the grain entering the warehouse can be displayed on the display 55, so that the user can know the weight of the grain entering the warehouse; the grain entering the granary will further squeeze the metering hose 41, so that the control slide 43 will move further on the basis of the original position, and the control slide 43 will drive the metering rod 52 to move. The displacement sensor 53 measures the movement displacement of the end of the metering rod 52 and outputs a displacement signal. Under the control of the second controller 54, the weight value of the grain entering the granary can be displayed on the display 55, so that the user can know the weight of the grain entering the granary, thereby making it convenient for the user to manage the grain entering the warehouse and the grain entering the granary.

[0050] Reference Figure 5 and Figure 6 In order to be able to respond to the storage situation of grain more flexibly, the closing plate 31 is fixedly penetrated with a rotating shaft 311, and the rotating shaft 311 is rotatably connected to the storage main pipe 1. The rotating shaft 311 is used to enable the closing plate 31 to open the bottom end of the guide cylinder 3. The bottom end of the storage main pipe 1 is provided with a transfer component 6. The transfer component 6 is used to transfer the bulk grain to the granary in other areas or transfer the bulk grain for processing when the closing plate 31 opens the bottom end of the guide cylinder 3.

[0051] When all the granaries connected to the storage pipe 1 are in a fully loaded state, the grain that continues to be stored needs to be transferred to the granaries in other areas for storage. At this time, the rotating shaft 311 needs to be rotated to open the closing plate 31 so that the bulk grain can flow to the bottom end of the storage pipe 1, and then the transfer component 6 arranged at the bottom end of the storage pipe 1 transfers the grain to the granaries in other areas to ensure that all the grain can be stored after being measured by the chute scale 51; when the stored grain cannot be directly stored due to quality problems, the rotating shaft 311 is also rotated to open the closing plate 31 so that the bulk grain can flow to the bottom end of the storage pipe 1, and then the transfer component 6 transfers the grain, so that the stored grain can be flexibly stored.

[0052] Specifically, refer to Figure 6 The transfer assembly 6 includes a transfer part 61, a first transfer control part 62 and a second transfer control part 63. The transfer part 61 includes a grain depot transfer pipe 611, a processing transfer pipe 612 and a transfer control plate 613. The bottom end of the storage main pipe 1 is respectively connected with one end of the grain depot transfer pipe 611 and the processing transfer pipe 612. The transfer control plate 613 is slidably arranged on the bottom end of the grain depot transfer pipe 611 and the bottom end of the processing transfer pipe 612. The transfer control plate 613 is used to close the grain depot transfer pipe 611 or the processing transfer pipe 612. Under normal conditions, the transfer control plate 613 closes the processing transfer pipe 612, so that the grain depot transfer pipe 611 is in a conducting state.

[0053] Reference Figure 5 and Figure 6 The first transfer control unit 62 is connected to all the electric gates 49. The first transfer control unit 62 is used to open the closing plate 31 when all the electric gates 49 are closed, so that the grain can be transferred to the granary in other areas. The second transfer control unit 63 is connected to the transfer control plate 613. The second transfer control unit 63 is used to open the closing plate 31 and drive the transfer control plate 613 to close the grain storage transfer pipe 611 when the grain needs to be processed, so that the grain can be transferred and processed.

[0054] When all the granaries connected to the inlet main pipe 1 are fully loaded, the first transfer control unit 62 can open the closing plate 31 to allow the bulk grain to flow to the bottom end of the inlet main pipe 1. Under the guidance of the transfer control plate 613, the bulk grain flows into the grain depot transfer pipe 611, so that the grain can be transferred to granaries in other areas; when there are quality problems with the grain, the second transfer control unit 63 can open the closing plate 31 to allow the bulk grain to flow to the bottom end of the inlet main pipe 1. The second transfer control unit 63 drives the transfer control plate 613 to close the grain depot transfer pipe 611, and puts the processing transfer pipe 612 in a conducting state, so that the grain can be transferred and processed.

[0055] In particular, refer to Figure 5 and Figure 7One end of the rotating shaft 311 rotates and passes through the storage pipe 1. The end of the rotating shaft 311 that passes through the storage pipe 1 is fixedly connected with a transfer gear 312. The transfer gear 312 is meshed with a transfer rack 313. The transfer rack 313 is slidably connected to the outer wall of the storage pipe 1, and the sliding direction is the vertical direction. A closing spring 314 is fixed between the transfer rack 313 and the storage pipe 1. The closing spring 314 is used to drive the transfer rack 313 to make the closing plate 31 close the bottom end of the guide cylinder 3.

[0056] Among them, refer to Figure 5 and Figure 7 The first transfer control part 62 includes a first magnetic block 621, a second magnetic block 622 and a magnetic isolation plate 623. The first magnetic block 621 is fixedly connected to the bottom end of the transfer rack 313, and the second magnetic block 622 is fixedly connected to the processing transfer tube 612 and is arranged opposite to the first magnetic block 621. The polarities of the first magnetic block 621 and the second magnetic block 622 on the side close to each other are opposite. The first magnetic block 621 and the second magnetic block 622 are adsorbed on each other to drive the transfer rack 313 to make the closing plate 31 open the bottom end of the material guide cylinder 3.

[0057] Reference Figure 5 , Figure 7 and Figure 8 There are multiple magnetic isolation plates 623, and they correspond to the electric gates 49 one by one. The multiple magnetic isolation plates 623 are all set between the first magnetic block 621 and the second magnetic block 622, and are arranged in sequence along the direction from the first magnetic block 621 to the second magnetic block 622. The edge position of the magnetic isolation plate 623 is hinged to the processing transfer tube 612, and a torsion spring 6231 is set at the hinge between the magnetic isolation plate 623 and the processing transfer tube 612. The two ends of the torsion spring 6231 are respectively fixed to the magnetic isolation plate 623 and the processing transfer tube 612. The torsion spring 6231 is used to drive the magnetic isolation plate 623 to rotate between the first magnetic block 621 and the second magnetic block 622. When the magnetic isolation plate 623 is located between the first magnetic block 621 and the second magnetic block 622, the magnetic isolation plate 623 can block the magnetic attraction between the first magnetic block 621 and the second magnetic block 622, so that the transfer rack 313 can close the bottom end of the material guide cylinder 3 with the closing plate 31 under the elastic force of the closing spring 314.

[0058] Reference Figure 4 , Figure 6 and Figure 7A pull rope 624 is fixedly connected to the magnetic isolation plate 623, and one end of the pull rope 624 away from the magnetic isolation plate 623 is fixedly connected to the first rotation control rod 625. The first rotation control rod 625 is slidably penetrated on the storage branch pipe 2 corresponding to the electric gate 49, and one end of the first rotation control rod 625 away from the pull rope 624 is fixedly connected to the gate plate of the electric gate 49. Two pulling rings 6241 are slidably sleeved on the pull rope 624, and the two pulling rings 6241 are fixedly connected to the storage main pipe 1, one of the pulling rings 6241 is arranged close to the magnetic isolation plate 623, and the other pulling ring 6241 is arranged close to the first rotation control rod 625. The two pulling rings 6241 are used to make the pull rope 624 pull the magnetic isolation plate 623 to rotate when moving. When the electric gate 49 is closed, the first rotation control rod 625 pulls the pull rope 624 to make the magnetic isolation plate 623 rotate away from the area directly facing the first magnetic block 621 and the second magnetic block 622.

[0059] When the granary is fully loaded, the first controller 48 controls the electric gate 49 to close, and the gate of the electric gate 49 drives the first control rod 625 to move downward, and the first control rod 625 pulls the pull rope 624 to move, and under the cooperative guiding action of the two pull rings 6241, the pull rope 624 pulls the magnetic isolation plate 623 to rotate away from the area directly facing the first magnetic block 621 and the second magnetic block 622, so that when all the granaries are fully loaded, all the magnetic isolation plates 623 can rotate away from the area directly facing the first magnetic block 621 and the second magnetic block 622, so as to prevent the granary from being overloaded. The first magnetic block 621 can drive the transfer rack 313 to slide down under the magnetic attraction of the second magnetic block 622, the transfer rack 313 drives the transfer gear 312 to rotate, the transfer gear 312 drives the rotating shaft 311 to rotate, and the rotating shaft 311 drives the closing plate 31 to rotate, so that the closing plate 31 opens the bottom end of the guide cylinder 3, so that after all the granaries are fully loaded, the closing plate 31 can be automatically opened to allow the bulk grain to flow from the warehouse entrance main pipe 1 to the grain warehouse transfer pipe 611, so that the grain can be transferred to granaries in other areas.

[0060] Among them, refer to Figure 5 , Figure 6 and Figure 7 The second rotation control part 63 includes a second rotation control rod 631 and a push plate 632. One end of the second rotation control rod 631 is fixedly connected with a rotation control shaft 6311, and the rotation control shaft 6311 is rotatably connected to the storage main pipe 1. The other end of the second rotation control rod 631 is fixedly connected to the rotation control plate 613. The rotation control plate 613 is in the shape of an arc plate. The axis of the rotation control plate 613 coincides with the axis of the rotation control shaft 6311. The push plate 632 is fixedly connected to the second rotation control rod 631. One side of the push plate 632 abuts against the top of the transfer rack 313. The push plate 632 is used to drive the transfer rack 313 to make the closing plate 31 open the bottom end of the guide cylinder 3 when the second rotation control rod 631 swings to make the rotation control plate 613 close the grain storage transfer pipe 611.

[0061] When there is a quality problem with the grain, the second transfer control rod 631 is swung, and the second transfer control rod 631 drives the transfer control plate 613 to slide, so that the transfer control plate 613 opens the processing transfer pipe 612, and the transfer control plate 613 closes the grain storage transfer pipe 611. At the same time, the second transfer control rod 631 can drive the push plate 632 to swing, and the push plate 632 can push the transfer rack 313 downward to open the closing plate 31, so that the bulk grain can flow from the bottom end of the guide barrel 3 into the processing transfer pipe 612, so that the bulk grain can be transferred and processed.

[0062] Further, refer to Figure 6 and Figure 7 A fixing bolt 633 is threadedly passed through the second transfer rod 631. The fixing bolt 633 is used to be threadedly connected to the first fixing hole 13 or the second fixing hole 14 opened on the outer wall of the storage main pipe 1. When the fixing bolt 633 is connected to the first fixing hole 13, the second transfer rod 631 causes the transfer plate 613 to close the processing transfer pipe 612. When the fixing bolt 633 is connected to the second fixing hole 14, the second transfer rod 631 causes the transfer plate 613 to close the grain storage transfer pipe 611.

[0063] Connecting the fixing bolt 633 into the first fixing hole 13 or the second fixing hole 14 can fix the second turning control rod 631 and the storage main pipe 1, so that the state of the turning control plate 613 closing the processing transfer pipe 612 or closing the grain storage transfer pipe 611 is easy to maintain.

[0064] Furthermore, refer to Figure 5 and Figure 6 The rotation control shaft 6311 rotates and penetrates into the storage main pipe 1. One end of the rotation control shaft 6311 that penetrates into the storage main pipe 1 is fixedly connected with a rotation control gear 634. The rotation control gear 634 is meshed with a rotation control rack 635. The rotation control rack 635 is slidably connected to the storage main pipe 1, and the sliding direction is the vertical direction. The rotation control rack 635 is fixedly connected with a closed sleeve 636. The closed sleeve 636 is slidably inserted into the material guide barrel 3. The outer wall of the closed sleeve 636 is fitted with the inner wall of the material guide barrel 3. When the second rotation control rod 631 causes the rotation control plate 613 to close the grain storage transfer pipe 611, the closed sleeve 636 closes the storage hole 32.

[0065] When the second turning control rod 631 is swung to make the turning control plate 613 close the grain storage transfer pipe 611, the second turning control rod 631 drives the turning control gear 634 to rotate through the turning control shaft 6311, the turning control gear 634 drives the turning control rack 635 to slide, the turning control rack 635 drives the closing sleeve 636 to slide down, and the closing sleeve 636 closes the storage entrance hole 32, so that the bulk grain can only flow into the processing transfer pipe 612, thereby preventing the grain with quality problems from flowing into the granary.

[0066] The implementation principle of a metering and loading system for grain entering a warehouse in an embodiment of the present application is as follows: when in use, the movable end of the control telescopic rod 44 corresponding to the underloaded grain bin is clamped in the control groove 33, so that the entry hole 32 is connected with the entry branch pipe 2 corresponding to the underloaded grain bin, and the grain flows from the entry main pipe 1 through the guide tube 3 into the entry branch pipe 2, and then flows into the grain bin from the entry branch pipe 2. The grain squeezes the metering hose 41 in the grain bin, so that the hydraulic oil in the metering hose 41 flows into the control cavity 431, and the hydraulic oil pushes the control slide 43 to slide until the grain bin is fully loaded. At this time, the control slide 43 drives the movable end of the control telescopic rod 44 to disengage from the control groove 33. Under the drive of the magnetic disk 12, the entry hole 32 and the entry branch pipe 2 are misaligned, making it less likely for the grain bin to be underloaded or overloaded, thereby improving the accuracy of loading grain into the grain bin.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
