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 loading belt conveyor. The loading belt conveyor transports the bulk grain into each granary to realize grain storage.

[0003] When grain is brought into a warehouse, manual control of the grain silo's filling status is typically performed. Once the silo is full, the silo's loading channel is manually closed, and the loading belt conveyor then transports the bulk grain to other silos. Manually controlling the closure of the silo's loading channel can easily lead to underloading or overloading of the silo due to human error, resulting in poor accuracy in grain loading into the silo. Summary of the Invention

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

[0005] This application provides a grain storage metering and loading system, which adopts the following technical solutions:

[0006] A metering and loading system for grain storage, comprising:

[0007] Warehouse supervisor, responsible for admitting bulk grain;

[0008] There are multiple inlet branch pipes, which correspond to the granaries one by one. The multiple inlet branch pipes are arranged along the circumference of the inlet main pipe. One end of the inlet branch pipe is connected to the side wall of the inlet main pipe, and the other end is connected to the corresponding granary.

[0009] The guide barrel is rotatably arranged in the storage main pipe. The top of the guide barrel is used to receive bulk grain. The bottom of the guide barrel is provided with a closing plate, which closes the bottom of the guide barrel. The side wall of the guide barrel is provided with a storage hole, which is used to communicate with any storage branch pipe.

[0010] The control components are provided in multiple groups and correspond one to one with the granaries. The control components include a metering hose, a control box, a control slide, a control telescopic rod, a control spring and a return spring;

[0011] in,

[0012] 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;

[0013] The control box is connected to the side wall of the storage main pipe, and 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 and is connected to the end of the metering hose close to the top of the granary, and a fluid medium flows through the control cavity.

[0014] The fixed end of the control telescopic rod is connected to the side of the control slide close to the control cavity and is slidably installed on the control box. The movable end of the control telescopic rod is slidably installed on the side wall of the storage main pipe. The control spring is set in the rodless cavity of the control telescopic rod and is used to drive the control telescopic rod to fully extend.

[0015] The 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 toward 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 to the storage branch pipe corresponding to the control telescopic rod.

[0016] By adopting the above technical solution, since the grain in the granary is not full, the metering hose is only partially squeezed, and the return 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 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 inlet hole of the guide barrel. 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 main pipe, and also locate the warehouse hole and the warehouse branch pipe so that the warehouse hole is aligned with the warehouse branch pipe. The bulk grain in the guide barrel flows from the warehouse hole into the warehouse branch pipe, and flows from the warehouse branch pipe into the granary to fill the granary.

[0017] The bulk grain is gradually loaded into the granary, causing the bulk grain level in the granary to gradually increase. When the granary is full of grain, the grain squeezes the metering hose as a whole, allowing all the hydraulic oil in the metering hose to flow into the control cavity, driving the control slide to slide in the direction away from the inlet main pipe. The control slide drives the control telescopic rod to move. Before the granary is full, the movable end of the control telescopic rod can always keep the inlet hole and the inlet branch pipe connected with the elastic force of the control spring. After the granary is fully loaded, the control slide drives the movable end of the control telescopic rod to disengage from the control slot. At this time, the control telescopic rod is in a fully extended state.

[0018] After the movable end of the control telescopic rod disengages from the control slot, the guide barrel can continue to rotate until the movable end of the control telescopic rod corresponding to the next unfilled granary is engaged in the control slot of the guide barrel to fill the next unfilled granary, thereby allowing multiple granaries to be loaded with grain one by one, and automatically switching to the next granary for filling after the granary is full, making it less likely that the granary will be underloaded or overloaded, thereby improving the accuracy of loading grain into the granary.

[0019] Optionally, a magnetic ring is embedded on the outer wall of the material guide cylinder, a motor is connected to the outer wall of the storage main pipe, the output shaft of the motor is connected to a magnetic disk, and the side wall of the magnetic disk and the side wall of the magnetic ring are magnetically connected to each other.

[0020] By adopting the above technical solution, the magnetic disk is driven to rotate by the motor, and the magnetic disk drives the magnetic ring to rotate through the magnetic attraction force. The magnetic ring can drive the material guide barrel to rotate, so that the material guide barrel can drive the entry hole to align with 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, making it difficult for the motor to be damaged due to the fixation of the material guide barrel relative to the entry main pipe.

[0021] Optionally, a limit switch is provided on the side of the control slide away from the control chamber. The limit switch is connected to the inner wall of the control box and is used to output a position signal. The limit 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 point between the entry branch and the entry main. When the granary is full, the control slide is squeezed on the limit 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 limit switch, the first controller responds to the position signal, and is used to control the electric gate to open.

[0022] By adopting the above technical solution, 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 past 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 electric gate corresponding to the granary to close according to the position signal, so as to prevent the situation of continuing to fill when it is fully loaded, thereby further improving the stability of granary loading.

[0023] Optionally, a metering assembly is further included, comprising a chute scale, a metering rod, and a displacement sensor. The chute scale is connected to the feed end of the storage main and is used to output a weight signal of the stored grain. Multiple metering rods and displacement sensors are provided, and the metering rods and the control slides are in one-to-one correspondence. 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 provided on the control box.

[0024] The displacement sensor is connected to the warehouse 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 grain entering the warehouse. The second controller responds to the displacement signal and is used to control the display to display the weight value of the grain entering the warehouse.

[0025] By adopting the above technical solution, before the grain flows into the warehouse main pipe, all the grain will flow through the chute scale, the chute scale will measure the grain entering the warehouse and output a weight signal. Under the control of the second controller, the weight value of the grain entering the warehouse can be displayed on the display, 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, so that the control slide will move further on the basis of the original position, and the control slide will drive the metering rod to move. The displacement sensor measures the movement displacement of the end of the metering rod and outputs a displacement signal. 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 easier for the user to manage the grain entering the warehouse and the grain entering the granary.

[0026] Optionally, the closing plate is connected to a rotating shaft, which is rotatably connected to the storage main pipe. The rotating shaft is used to enable the closing plate to open the bottom end of the material guide barrel. A transfer component is provided at the bottom end of the storage main pipe. The transfer component is used to transfer bulk grain to granaries in other areas or transfer bulk grain for processing when the closing plate opens the bottom end of the material guide barrel.

[0027] By adopting the above technical solution, when all the grain silos connected to the storage main are in a full state, the grain that continues to be stored needs to be transferred to the grain silos in other areas for storage. At this time, the rotating shaft needs to be rotated to open the closing plate so that the bulk grain can flow to the bottom end of the storage main, and then the transfer component set at the bottom end of the storage main will transfer the grain to the grain silos in other areas to ensure that all the grain can be stored after being measured by the chute scale; when the stored grain cannot be directly stored due to quality problems, the rotating shaft is also rotated to open the closing plate so that the bulk grain can flow to the bottom end of the storage main, and then the transfer component will transfer the grain for processing, so that the stored grain can be flexibly stored.

[0028] Optionally, the transfer assembly includes a transfer part, a first transfer control part and a second transfer control part, the transfer part includes a grain depot transfer pipe, a processing transfer pipe and a transfer control plate, the bottom end of the storage main pipe is connected to one end of the grain depot transfer pipe and the processing transfer pipe respectively, the transfer control plate is slidably arranged on the grain depot transfer pipe and the processing transfer pipe, the transfer control plate is used to close the grain depot transfer pipe or the processing transfer pipe, and under normal conditions, the transfer control plate closes the processing transfer pipe, so that the grain depot transfer pipe is in a conducting state;

[0029] The first transfer control unit is connected to all the electric gates, and the first transfer control unit is used to open the closing plate when all the electric gates are closed; the second transfer control unit is connected to the transfer control plate, and the second transfer control unit is used to open the closing plate when the grain needs to be processed and drive the transfer control plate to close the grain storage transfer pipe.

[0030] By adopting the above technical solution, when all the granaries connected to the inlet main pipe are fully loaded, the first transfer control unit can open the closing plate to allow the bulk grain to flow to the bottom end of the inlet main pipe. Under the guidance of the transfer control plate, the bulk grain flows into the granary transfer pipe, 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 can open the closing plate to allow the bulk grain to flow to the bottom end of the inlet main pipe. The second transfer control unit drives the transfer control plate to close the granary transfer pipe and puts the processing transfer pipe in a conductive state, so that the grain can be transferred and processed.

[0031] Optionally, one end of the rotating shaft rotates to pass through the storage pipe, and the end of the rotating shaft passing through the storage pipe is connected to a transfer gear, the transfer gear is engaged with a transfer rack, the transfer rack is slidably connected to the outer wall of the storage pipe, and a closing spring is provided between the transfer rack and the storage pipe, and the closing spring is used to drive the transfer rack to make the closing plate close the bottom end of the guide cylinder;

[0032] The first transfer control unit includes a first magnetic block, a second magnetic block, and a magnetic isolation plate. The first magnetic block is connected to one end of the transfer rack, and the second magnetic block is connected to the processing transfer tube and is arranged opposite to the first magnetic block. The polarities of the first and second magnetic blocks are opposite on the sides close to each other. The first and second magnetic blocks are attracted to each other to drive the transfer rack to cause the closing plate to open the bottom end of the material guide cylinder.

[0033] A plurality of magnetic isolation plates are provided, and correspond one to one with the electric gates. The plurality of magnetic isolation plates are all provided between the first magnetic block and the second magnetic block, and are arranged in sequence along the direction from the first magnetic block to the second magnetic block. The edge position of the magnetic isolation plate is hinged to the processing transfer tube. A torsion spring is provided at the hinge between the magnetic isolation plate and the processing transfer tube. The torsion spring is used to drive the magnetic isolation plate to rotate between the first magnetic block and the second magnetic block.

[0034] A pull rope is connected to the magnetic isolation plate, and the pull rope is connected to a first rotation control rod. The first rotation control rod is slidably penetrated on the storage branch pipe corresponding to the electric gate, and the first rotation control rod is connected to the gate plate of the electric gate. Two pulling rings are slidingly sleeved on the pull rope, and the two pulling rings are connected to the storage main pipe. The two pulling rings are used to make the pull rope pull the magnetic isolation plate to rotate when moving. When the electric gate is closed, the first rotation control rod pulls the pull rope to rotate the magnetic isolation plate away from the area directly facing the first magnetic block and the second magnetic block.

[0035] By adopting the above technical solution, when the granary is fully loaded, the first controller controls the electric gate to close, the gate of the electric gate drives the first turning control rod to move downward, the first turning control rod pulls the pull rope to move, and under the cooperative guiding action of the two pulling rings, the pull rope pulls the magnetic isolation plate to rotate away from the area directly facing the first magnetic block and the second magnetic block, so that when all granaries are fully loaded, all magnetic isolation plates can be rotated away from the area directly facing the first magnetic block and the second magnetic block, so that the first magnetic block can drive the transfer rack to slide down under the magnetic attraction of the second magnetic block, the transfer rack drives the transfer gear to rotate, the transfer gear drives the rotating shaft to rotate, and the rotating shaft drives the closing plate to rotate, so that the closing plate opens the bottom end of the material guide cylinder, so that after all granaries are fully loaded, the closing plate can be automatically opened to allow bulk grain to flow from the warehouse main pipe to the grain warehouse transfer pipe, so that the grain can be transferred to granaries in other areas.

[0037] By adopting the above technical solution, when there is a quality problem with the grain, the second turn control rod is swung, and the second turn control rod drives the turn control plate to slide, so that the turn control plate opens the processing transfer pipe and closes the grain storage transfer pipe. At the same time, the second turn control rod can drive the push plate to swing, and the push plate can push the transfer rack downward to open the closing plate, so that the bulk grain can flow from the bottom end of the guide barrel into the processing transfer pipe, so that the bulk grain can be transferred and processed.

[0038] Optionally, a fixing bolt is threaded through the second turning control rod, and the fixing bolt is used to be threadedly connected to a first fixing hole or a second fixing hole opened on the outer wall of the warehouse entrance main pipe. When the fixing bolt is connected to the first fixing hole, the second turning control rod causes the turning control plate to close the processing transfer pipe.

[0056] The following is combined with Figure 1-8 This application is described in further detail.

[0057] The embodiment of the present application discloses a metering and loading system for grain storage. Figure 1 and Figure 2 A grain storage metering and loading system includes a storage main pipe 1, a storage branch pipe 2, a material guide cylinder 3 and a control component 4.

[0058] Reference Figure 1 The main inlet pipe 1 is used to bring in bulk grain. Multiple branch inlet pipes 2 are provided, corresponding one to one with the granary. 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.

[0059] Reference Figure 2 The guide cylinder 3 is rotatably arranged in the storage main pipe 1. The top of the guide cylinder 3 is used to receive bulk grain. The bottom end of the guide cylinder 3 is provided with a closing plate 31. The closing plate 31 closes the bottom end of the guide cylinder 3. An entry hole 32 is opened on the side wall of the guide cylinder 3. The entry hole 32 is used to communicate with any one of the storage branch pipes 2 to guide the bulk grain into the connected storage branch pipe 2.

[0060] A rotating ring is fixedly connected to the material guide cylinder 3, and a rotating groove is opened on the storage main pipe 1. The rotating ring is rotatably set in the rotating groove. The rotating ring and the rotating groove form a rotating connection structure between the material guide cylinder 3 and the storage main pipe 1.

[0061] Reference Figure 2 、 Figure 3 and Figure 4 There are multiple groups of 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 43, a control telescopic rod 44, a control spring 45 and a return spring 46.

[0062] 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. 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.

[0063] 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. The sliding direction of the control slide 43 is the direction of approaching or moving 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. 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.

[0064] Reference Figure 4 The fixed end of the telescopic control rod 44 is fixedly connected to the side of the control slide 43 near the control cavity 431. The fixed end of the telescopic control rod 44 slides through the control box 42, and the movable end of the telescopic control rod 44 slides through the side wall of the storage main 1. A control spring 45 is disposed within the rodless cavity of the telescopic control rod 44. The ends of the control spring 45 are respectively fixedly connected to the fixed and movable ends of the telescopic control rod 44. The control spring 45 is used to drive the telescopic control rod 44 to fully extend.

[0065] A return spring 46 is positioned on the side of the control slide 43 away from the control chamber 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 toward the main inlet pipe 1. A control slot 33 is defined in the guide barrel 3. This slot 33 is designed to engage the movable end of any telescopic control rod 44. When the movable end of a telescopic control rod 44 is engaged in the slot 33, the inlet hole 32 communicates with the corresponding inlet branch pipe 2 of the telescopic control rod 44. By engaging the movable end of the telescopic control rod 44 in the slot 33, the inlet hole 32 and the corresponding inlet branch pipe 2 can be precisely positioned, ensuring that bulk grain flows easily and accurately into the branch pipe 2.

[0066] 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 squeeze on the outer wall of the guide cylinder 3, and the bulk grain entering the warehouse first flows into the storage 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 storage 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. The movable end of the control telescopic rod 44 is clamped in the control groove 33 under the elastic action of the control spring 45 to fix the guide cylinder 3 and the storage main pipe 1, and at the same time position the storage hole 32 and the storage branch pipe 2 so that the storage hole 32 is aligned with the storage branch pipe 2, and the bulk grain in the guide cylinder 3 flows from the storage hole 32 into the storage branch pipe 2, and flows into the granary from the storage branch pipe 2 to fill the granary.

[0067] The bulk grain gradually fills the granary, causing the bulk grain level in the granary to gradually increase. 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, thereby driving the control slide 43 to slide in the direction away from the storage main pipe 1. The control slide 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 43 drives the movable end of the control telescopic rod 44 to disengage from the control groove 33. At this time, the control telescopic rod 44 is in a fully extended state.

[0068] After the movable end of the control telescopic rod 44 disengages from the control slot 33, the 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 slot 33 of the guide cylinder 3 to fill the next unfull granary, thereby allowing multiple granaries to be loaded one by one, and automatically switching to the next granary for filling after the granary is full, making it less likely for the granary to be underloaded or overloaded, thereby improving the accuracy of loading and storing granaries.

[0069] Further, refer to Figure 5 A magnetic ring 34 is fixedly embedded on the outer wall of the material guide cylinder 3, a motor 11 is fixedly connected to the outer wall of the storage main pipe 1, and a magnetic disk 12 is fixedly connected to the output shaft of the motor 11. The side wall of the magnetic disk 12 is arranged opposite to the side wall of the magnetic ring 34, and they are magnetically connected to each other.

[0070] The magnetic disk 12 is driven to rotate by the motor 11, and the magnetic disk 12 drives the magnetic ring 34 to rotate through the magnetic attraction force. 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, making it difficult for the motor 11 to be damaged due to the fixation of the material guide barrel 3 relative to the entry branch pipe 1.

[0071] Furthermore, refer to Figure 1 and Figure 4 A limit switch 47 is provided on the side of the control slide 43 away from the control chamber 431. The limit switch 47 is fixedly connected to the inner wall of the control box 42 and is used to output a position signal. The limit 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 warehouse branch pipe 2 and the warehouse main pipe 1. When the granary is fully loaded, the control slide 43 is squeezed on the limit 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 limit switch 47, and the first controller 48 responds to the position signal and is used to control the electric gate 49 to open.

[0072] Since the entry hole 32 is connected to each entry branch 2 one by one, when there is a fully loaded granary between the 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 limit switch 47 can be used to feedback its own full load situation. 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.

[0073] Reference Figure 1 and Figure 4In order to accurately measure the incoming grain and the grain entering the granary, so as to facilitate the management of grain entering the granary, a grain entering the granary 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 entry main 1 and is used to output the weight signal of the incoming grain, and accurately measure the weight of the incoming and outgoing grain in a mobile weighing manner; there are multiple metering rods 52 and displacement sensors 53, and they correspond one to one. The metering rods 52 correspond one to one with the control slide 43. 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 into the control box 42. The movement displacement of the metering rod 52 can directly feedback the grain loading situation in the granary.

[0074] A displacement sensor 53 is connected to the inbound main pipe 1 and is positioned opposite the end of the metering rod 52 away from the control box 42. The displacement sensor 53 is configured to output a displacement signal. The chute scale 51 and all of the displacement sensors 53 are electrically connected to a second controller 54, which is fixedly attached to a ground-based control base. The second controller 54 is electrically connected to a display 55, which is also fixedly attached to the ground-based control base. The second controller 54 responds to the weight signal and controls the display 55 to display the weight of the incoming grain. The second controller 54 responds to the displacement signal and controls the display 55 to display the weight of the incoming grain.

[0075] Before the grain flows into the warehouse main pipe 1, all the grain will flow through the chute scale 51. The chute scale 51 measures the grain entering the warehouse and outputs 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, causing the control slide 43 to move further on the basis of the original position. The control slide 43 drives the metering rod 52 to move, and 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 easier for the user to manage the grain entering the warehouse and the grain entering the granary.

[0076] Reference Figure 5 and Figure 6 In order to be able to respond to the grain storage situation more flexibly, the closing plate 31 is fixedly penetrated by 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 bulk grain to granaries in other areas or transfer bulk grain for processing when the closing plate 31 opens the bottom end of the guide cylinder 3.

[0077] When all the grain silos connected to the inlet main pipe 1 are in a full state, the grain that continues to be stored needs to be transferred to the grain silos 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 inlet main pipe 1, and then the transfer component 6 set at the bottom end of the inlet main pipe 1 transfers the grain to the grain silos 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 inlet main pipe 1, and then the transfer component 6 transfers the grain, so that the stored grain can be flexibly stored.

[0078] Specifically, refer to Figure 6 The transfer assembly 6 includes a transfer unit 61, a first transfer control unit 62, and a second transfer control unit 63. The transfer unit 61 includes a grain depot transfer pipe 611, a processing transfer pipe 612, and a transfer control plate 613. The bottom end of the inlet main pipe 1 is connected to one end of the grain depot transfer pipe 611 and the processing transfer pipe 612, respectively. The transfer control plate 613 slides through the bottom ends of the grain depot transfer pipe 611 and the bottom ends of the processing transfer pipe 612. The transfer control plate 613 is used to seal the grain depot transfer pipe 611 or the processing transfer pipe 612. Under normal conditions, the transfer control plate 613 seals the processing transfer pipe 612, leaving the grain depot transfer pipe 611 in a conductive state.

[0079] Reference Figure 5 and Figure 6 The first control unit 62 is connected to all electric gates 49 and is used to open the sealing plate 31 when all electric gates 49 are closed, allowing grain to be transferred to other granaries. The second control unit 63 is connected to the control plate 613 and is used to open the sealing plate 31 and drive the control plate 613 to close the grain storage transfer pipe 611 when grain needs to be processed, allowing grain to be transferred and processed.

[0080] 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 guiding action of the transfer control plate 613, the bulk grain flows into the granary 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 granary transfer pipe 611, and puts the processing transfer pipe 612 in a conductive state, so that the grain can be transferred and processed.

[0081] In particular, refer to Figure 5 and Figure 7One end of the rotating shaft 311 rotates and passes through the input and output main pipe 1. The end of the rotating shaft 311 that passes through the input and output main pipe 1 is fixedly connected with a transfer gear 312. The transfer gear 312 is engaged with a transfer rack 313. The transfer rack 313 is slidably connected to the outer wall of the input main pipe 1, and the sliding direction is vertical. A closing spring 314 is fixed between the transfer rack 313 and the input main 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 barrel 3.

[0082] Among them, reference 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.

[0083] Reference Figure 5 、 Figure 7 and Figure 8 There are multiple magnetic isolation plates 623, and they correspond one to one with the electric gate 49. The multiple magnetic isolation plates 623 are all arranged 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 provided 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 fixedly connected 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.

[0084] Reference Figure 4 、 Figure 6 and Figure 7, a pull rope 624 is fixedly connected to the magnetic isolation plate 623, and the end of the pull rope 624 away from the magnetic isolation plate 623 is fixedly connected to the first rotation control rod 625, and the first rotation control rod 625 is slidably penetrated on the storage branch pipe 2 corresponding to the electric gate 49, and the 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 slidingly 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 cooperate 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 rotate the magnetic isolation plate 623 away from the area directly facing the first magnetic block 621 and the second magnetic block 622.

[0085] 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 turning control rod 625 to move downward, and the first turning control rod 625 pulls the pull rope 624 to move. Under the cooperative guidance of the two pulling rings 6241, the pull rope 624 pulls the magnetic isolation plate 623 to rotate away from the area where the first magnetic block 621 and the second magnetic block 622 are facing. Therefore, when all the granaries are fully loaded, all the magnetic isolation plates 623 can rotate away from the area where the first magnetic block 621 and the second magnetic block 622 are facing. The first magnetic block 621 can drive the transfer rack 313 to slide down under the action of the magnetic attraction of the second magnetic block 622, and the transfer rack 313 drives the transfer gear 312 to rotate, and 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 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.

[0086] Among them, reference 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. 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 an arc-shaped 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.

[0087] 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.

[0088] 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.

[0089] 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 warehouse entrance main pipe 1, so that the state of the turning control plate 613 closing the processing transfer pipe 612 or closing the grain warehouse transfer pipe 611 is easy to maintain.

[0090] 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 engaged 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 vertical. 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.

[0091] When the second control rod 631 is swung to make the control plate 613 close the grain storage transfer pipe 611, the second control rod 631 drives the control gear 634 to rotate through the control shaft 6311, and the control gear 634 drives the control rack 635 to slide, and the control rack 635 drives the closing sleeve 636 to slide down, and the closing sleeve 636 closes the storage hole 32, so that the bulk grain can only flow into the processing transfer pipe 612, thereby preventing grain with quality problems from flowing into the granary.

[0092] 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 cylinder 3 into the entry branch pipe 2, and then flows from the entry branch pipe 2 into the grain bin. 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 that the grain bin will be underloaded or overloaded, thereby improving the accuracy of loading grain into the grain bin.

[0093] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
