Description

Technical Field

[0001] This invention relates to the field of rice processing equipment technology, and in particular to a conveying and storage system for rice processing. Background Technology

[0002] Rice is one of the staple foods in my country, and its processing methods have continuously evolved with the improvement of people's living standards. The process of processing paddy into edible rice generally involves several steps. Currently, the main processes for paddy processing include pre-cleaning, hulling, milling, and finished product finishing.

[0003] For some large processing plants, the processed rice is temporarily stored in grain warehouses. When it is ready to be sold, it is unloaded from the grain warehouses and packaged for sale. Because the rice is graded, conveyor belts are generally used to transport the exposed rice to different grade grain warehouses. This system occupies a large area and has a high cost. At the same time, the exposed rice will suffer some losses and generate a lot of dust during transportation, which will affect the environment. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying and storage system for rice processing, which has the advantages of automatically classifying and storing rice of different specifications, effectively preventing rice from being contaminated, and having a small footprint and high work efficiency throughout the entire process.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: It includes several rows of parallel rice bins, each row of which includes several rice bin cylinders for holding rice of different specifications. A conveyor frame parallel to the rice bins is provided on one side of each row of rice bins. Parallel feeding and discharging frames are respectively provided on both sides of the conveyor frame, perpendicular to the conveyor frame. A loading frame parallel to the conveyor frame is provided at one end of each feeding and discharging frame. The conveyor frame, feeding frame, discharging frame, and loading frame are... All are rotatably connected to rotating rollers. Rice boxes are slidably conveyed on the conveyor frame, feeding frame, discharging frame and loading frame. Each rice box has a drive rod slidably connected to the side plate of the rice box. The drive rod can be intermittently engaged with the connecting rod on the outer side of the rice bin. A box cover is slidably connected to one side of the rice box. Two rotatable door panels are symmetrically arranged on the side of each rice bin on the same side as the connecting plate. The conveyor frame is equipped with a drive assembly that drives the door panels to rotate and the box cover to flip after the drive rod is engaged with the connecting rod.

[0006] By adopting the above technical solution, and by setting up conveyor racks, feeding racks, discharging racks, and loading racks, rice can be circulated and collected into rice bins. The number of conveyor racks, i.e., the number of rice bin groups, can be increased or decreased according to the factory size, making it suitable for different factories to control the floor space of the entire process according to their own needs, demonstrating strong adaptability. Simultaneously, rice is transported in rice boxes to prevent spillage or contamination during transportation. Furthermore, since each row of rice bin groups has multiple rice bins, different qualities or specifications of rice can be used to effectively classify and recycle the rice. Setting up multiple rows of rice bin groups ensures that different specifications of rice can be simultaneously recycled into the rice bins, improving work efficiency. A control system controls the transportation of each rice box to the designated rice bin in the rice bin group, forming an efficient transportation route and avoiding confusion. With the drive components in place, the rice bins and rice boxes automatically open, ensuring that rice in the rice boxes is smoothly put into the rice bins, and fully automatic unloading further improves work efficiency.

[0007] A further configuration of the present invention is as follows: the connecting rod is vertically fixed in the lifting rack, the lifting rack meshes externally with a rotating gear, a driving bevel gear is coaxially fixed to the rotating gear, the driving bevel gear is externally meshed with a driving bevel gear, the driving bevel gear is coaxially fixed to a driving bevel gear, the driving bevel gear is coaxially fixed to a driving bevel gear, the driving bevel gear is coaxially meshed with a driving bevel gear, and the driving bevel gear is coaxially fixed to two driving bevel gears, a first driving bevel gear and a second driving bevel gear, with opposite tooth directions, the driving bevel gears are respectively externally meshed with driven driving bevel gears, a first driving bevel gear and a second driving bevel gear, fixed to the top of the two door panels.

[0008] By adopting the above technical solution, when the drive rod rises, it engages with the connecting rod. As the drive rod rises further, it pushes the connecting rod to drive the lifting rack to rise. The lifting rack drives the rotating gear one to rotate clockwise, which in turn drives the bevel gear one to rotate clockwise. Then, the driving bevel gear two, driving bevel gear three, and driving bevel gear four all rotate clockwise, further driving the driving bevel gear one and driving bevel gear two to rotate clockwise. Since the driving bevel gear one and driving bevel gear two have tooth surfaces facing opposite directions, they ultimately drive the driven bevel gear one to rotate clockwise and the driven bevel gear two to rotate counterclockwise, thus opening the two door panels. The opening action of the rice bin is completed when the drive rod rises, which facilitates the subsequent unloading of rice into the rice bin.

[0009] A further configuration of the present invention is as follows: the driving assembly further includes a rack slidably connected to the side of the rice container; the driving rod is vertically fixed to the end of the rack near the rice hopper; the rack meshes externally with a driving gear located above the rack; a rotating shaft is fixed at the center of the driving gear; the rotating shaft passes through the other side of the rice container and is fixed with a driven gear; a driven gear is externally meshed with a driven gear; a driving pulley is coaxially fixed to the driven gear; the driving pulley and the driven pulley are connected by a belt; the driven pulley is coaxially fixed with the driven gear. A rotating rod is fixed to the shaft. There are two rotating rods, which are symmetrically connected to the inside of the rice box. One end of the rotating rod is hinged to the inside of the box cover, and the other end is hinged to a short rod. A spring is connected to the short rod, and the other end of the spring is connected to a second short rod. The spring drives the first short rod to move closer to the second short rod. The second short rod is fixed to the inside of the rice box. A concave groove is provided on both sides of the box cover near the two rotating rods. A slider is hinged to the end edge of the top cover of the rice box. The slider is slidably connected to the concave groove. A feed inlet is provided on the top of the rice box.

[0010] By adopting the above technical solution, after the drive rod and connecting rod are engaged, the lifting rack slides to open the door of the rice bin. Since rack one is slidably connected to the side of the rice box, rack one remains stationary when the rice box is pushed closer to the rice bin. When the rice box moves, the driving gear one meshing with rack one rotates clockwise, and the driven gear one rotates clockwise, further driving driven gear two to rotate counterclockwise. Finally, the driving pulley and the driven pulley rotate counterclockwise, and the rotating rod inside the rice box rotates counterclockwise. The rotating rod then drives the lid of the rice box to rotate counterclockwise, and the sliding groove on the inner side of the lid... Sliding the slider on the top cover flips open the rice box lid. A spring between short rods one and two pulls the rotating rod clockwise, ensuring the lid is sealed when not under stress. Once the lid flips, the rice is unloaded into the rice hopper, automatically completing the unloading process. The rice hopper opens its door first, and then the rice box flips open as it approaches, ensuring the rice falls smoothly into the hopper. The inlet at the top of the hopper allows for refilling after unloading. The refilling process can be performed using conventional techniques, which will not be detailed here.

[0011] A further configuration of the present invention is as follows: the driving assembly further includes two conveying plates located at the bottom of the rice box, a first conveying roller rotatably connected to the conveying plate, the rotation direction of the first conveying roller being perpendicular to the rotation direction of the rotating roller in the conveying frame, the conveying plates being respectively vertically fixed to the top of the two vertical plates of the U-shaped slide plate, a rotating wheel being rotatably connected to the outer side of the two vertical plates of the U-shaped slide plate, the rotating wheel being slidably engaged in a second sliding groove on the opposite side of the moving frame, the second sliding groove being inverted L-shape, the crossbar of the U-shaped slide plate being hinged to the piston rod end of the first driving cylinder, the other end of the first driving cylinder being hinged to the moving frame, the upper end of the moving frame being open, and two other opposite outer sides of the moving frame being fixed with sliding rods, the sliding rods being slidably connected to the conveying frame, the moving frame above one sliding rod being connected to a first conveyor belt, the first conveyor belt being rotatably connected to the conveying frame.

[0012] By adopting the above technical solution, when the conveyor belt rotates, the moving frame slides to the side of the designated rice bin under the drive of the control system. After the rice box slides above the conveyor plate and the drive rod on the rice box and the connecting rod on the rice bin sense the signal, the piston rod of the drive cylinder extends. The drive cylinder first slides in the vertical groove of the slide chute two, lifting the rice box. At this time, the drive rod and the connecting rod engage. During the upward movement, the door of the rice bin is opened. As the piston rod of the drive cylinder further extends, the slide plate begins to slide in the horizontal groove of the slide chute two, pushing the conveyor plate closer to the rice bin. Since the drive rod and the connecting rod are engaged, and the rack is slidably connected to the rice box, when the rice box is close to the rice bin, the rack does not move. The multiple gears meshing with the rack rotate, completing the subsequent flipping of the rice box cover, shortening the distance between the rice box and the rice bin, and ensuring smooth unloading.

[0013] A further feature of the present invention is that: a rotating shaft located at the center of the drive gear passes through and is fixed to a discharge plate inside the rice box; the discharge plate is rotatably connected to the rice box; the discharge plate is hollow and has an extension plate slidably connected inside; the other end of the extension plate away from the discharge plate is hinged and slidably connected to the inner side of the rice box away from the lid.

[0014] By adopting the above technical solution, as the rice box gradually approaches the rice silo, the drive gear rotates clockwise, and the unloading plate inside the rice box also rotates clockwise. The unloading plate forms an inclined shape, which is conducive to pouring as much rice as possible from the rice box into the rice silo, improving the cleanliness of rice unloading. An extension plate is set in the unloading plate, and the end of the extension plate is hinged and slidably connected to the inside of the rice box, which can ensure that the unloading plate can be smoothly flipped counterclockwise.

[0015] A further configuration of the present invention is as follows: a second driving gear is rotatably connected below the rack, the rack and the second driving gear mesh externally, the toothed portion below the rack is longer than the toothed portion above the rack, the second rack is slidably connected to the side of the rice box below the second driving gear, the second rack meshes externally with the second driving gear, the second rack passes through one side of the rice box and is connected to an extension plate at the bottom of the rice box, and the extension plate is slidably connected in a slot at the bottom of the rice box.

[0016] By adopting the above technical solution, when the rice box is close to the rice hopper, the second drive gear located below the rack rotates counterclockwise. The second rack, which is meshed below the second drive gear, slides towards the rice hopper. The rack then drives the extension plate to extend out of the rice hopper. The extension plate can penetrate into the already opened rice hopper, providing a certain guiding effect for the unloading of the rice box when the lid is opened. This ensures that all the rice falls into the rice hopper and avoids leaving rice outside and causing waste. The toothed part below the rack is longer than the toothed part above the rack, ensuring that the extension plate extends first. After penetrating into the rice hopper, the lid is then opened for unloading.

[0017] A further configuration of the present invention is as follows: a reversing assembly is slidably connected to both the feeding rack and the discharging rack. The reversing assembly includes a reversing plate, and a second conveying roller is rotatably connected to the reversing plate. The rotation direction of the second conveying roller is perpendicular to the rotation direction of the rotating rollers in the feeding rack and the discharging rack. The reversing plate is vertically fixed to the piston rod of the second driving cylinder. The other end of the second driving cylinder is fixed to a support plate. The support plate is connected to a second conveyor belt. The second conveyor belt is rotatably connected to the feeding rack and the discharging rack.

[0018] By adopting the above technical solution, when it is determined that the rice box needs to enter the conveyor frame from the feeding rack, the control system drives the support plate to slide to the designated area. After the rice box slides to the reversing plate, the piston rod of the second driving cylinder extends, lifting the rice box. Under the rotation of the second conveyor roller or by using other driving devices, the rice box is driven to vertically reverse onto the conveyor frame. Similarly, after the rice box is unloaded, when the conveyor frame enters the discharge rack, the piston rod of the second driving cylinder is in an extended state to ensure that the rice box is smoothly connected to the reversing plate. Then, the piston rod of the second driving cylinder retracts, and the rice box falls onto the discharge rack. Under the rotation of the roller, it is pushed into the loading rack, thus smoothly completing the unloading and loading of the rice box and proceeding in an orderly manner, improving the work efficiency of the entire process.

[0019] A further feature of the present invention is that it also includes a control system, which controls the movement of the moving frame and the support plate in the conveying frame, the feeding frame and the discharging frame, as well as the sensing of the drive rod and the connecting rod. The drive cylinder in each of the conveying frames is signal-connected to the rice bin that needs to be fed in each row of rice bins. The drive cylinder, the drive rod and the connecting rod are signal-connected.

[0020] By adopting the above technical solution and designing the control system, rice bin, and rice box structure, the rice in the rice box is smoothly unloaded into the rice bin. The whole process is highly automated, significantly improving the accuracy and efficiency of classification, summarization, and recycling.

[0021] A further feature of the present invention is that: an L-shaped baffle is provided at the end of the discharge rack near the loading rack and at the end of the loading rack near the feeding rack. A first adjusting cylinder and a second adjusting cylinder are respectively provided in the baffle. The piston rod of the first adjusting cylinder is in the same direction as the rotation of the transfer roller in the loading rack, and the piston rod of the second adjusting cylinder is in the same direction as the rotation of the transfer roller in the feeding rack.

[0022] By adopting the above technical solution, when the unloaded rice box moves from the discharge rack to near the loading rack, the first directional cylinder is activated, pushing the rice box into the loading rack with its posture unchanged. After sliding to the end of the loading rack, the rice box can be loaded here. The loading process can be carried out using conventional technical means, which will not be described in detail in this invention. After the loading is completed, the second directional cylinder is activated to drive the rice box into the feeding rack. At this time, the posture of the rice box will not change, ensuring that the rice box is unloaded smoothly.

[0023] A further feature of the present invention is that a guide plate is provided at the end of the conveyor frame near the feed frame.

[0024] By adopting the above technical solution, the guide plate can ensure that the rice box is in the correct posture when entering the conveyor frame, and ensure that the drive rod and the connecting rod can be smoothly sensed and engaged.

[0025] The beneficial effects of this invention are as follows: By setting up conveyor racks, feeding racks, discharging racks, and loading racks, rice can be circulated and collected into rice bins. The number of conveyor racks, i.e., the number of rice bin groups, can be increased or decreased according to the size of the factory, making it suitable for different factories to control the floor space occupied by the entire process according to their own circumstances, demonstrating strong adaptability. Simultaneously, rice is transported in rice boxes, preventing spillage or contamination during transportation. Furthermore, since each row of rice bin groups has multiple rice bins, different qualities or specifications of rice can be placed, effectively classifying and recycling the rice. Setting up multiple rows of rice bin groups ensures that different specifications of rice can be simultaneously recycled into the rice bins, improving work efficiency. Moreover, by setting up a control system, each rice box is transported to the designated rice bin in the rice bin group, forming an efficient transportation route and avoiding confusion. With the drive component, the rice bins and rice boxes automatically open, ensuring that the rice in the rice boxes is smoothly put into the rice bins, and fully automatic unloading further improves work efficiency.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] An example is a conveying and storage system for rice processing, such as... Figure 1-8As shown, the system includes several rows of parallel rice bins. Each row of rice bins includes several rice bin cylinders 1 for storing rice of different sizes. A conveyor frame 2 parallel to the rice bins is located on one side of each row of rice bins. Parallel feeding racks 3 and discharging racks 4 are located on both sides of the conveyor frame 2, perpendicular to the conveyor frame 2. A loading rack 5 parallel to the conveyor frame 2 is located at one end of each feeding rack 3 and discharging rack 4. Rotary rollers 7 are rotatably connected to the conveyor frame 2, feeding rack 3, discharging rack 4, and loading rack 5. Rice boxes 6 are slidably conveyed on the conveyor frame 2, feeding rack 3, discharging rack 4, and loading rack 5. A drive rod 8 is slidably connected to the side plate of each rice box 6. The drive rod 8 can communicate with a connecting rod 9 located on the outer side of the rice bin cylinder 1. After the connection is made, it intermittently engages. The connecting rod 9 is vertically fixed in the lifting rack 22. The lifting rack 22 meshes externally with the rotating gear 1 23. The rotating gear 1 23 is coaxially fixed with the driving bevel gear 1 24. The driving bevel gear 1 24 meshes externally with the driving bevel gear 25. The driving bevel gear 25 is coaxially fixed with the driving bevel gear 3 26. The driving bevel gear 3 26 meshes externally with the driving bevel gear 4 27. The driving bevel gear 4 27 is coaxially fixed with two driving bevel gears 1 28 and 2 29 with opposite tooth directions. The driving bevel gears 1 28 and 2 29 mesh externally with the driven driving bevel gears 1 30 24 and 2 31 25 fixed to the top of the two door panels 11, respectively. The driving rod 8 is vertically fixed to the rack 1. Near the end of the rice bin 1, rack 12 meshes with a drive gear 13 located above rack 12. A rotating shaft is fixed at the center of drive gear 13, which passes through the other side of rice bin 6 and is fixed with driven gear 14. Driven gear 14 meshes with driven gear 15. Driven gear 15 is coaxially fixed with drive pulley, which is connected to driven pulley via belt. Rotating rods 16 are coaxially fixed with driven pulley, and there are two rotating rods 16 that are symmetrically connected inside rice bin 6. One end of rotating rod 16 is hinged to the inside of bin cover 10, and the other end is hinged to short rod 17. A spring 18 is connected to short rod 17, and the other end of spring 18 is connected to short rod 19. Spring 18 drives short rod 17 to approach... Short rod 219 is fixed inside the rice box 6. The box cover 10 has concave grooves 20 on both sides near the two rotating rods 16. A slider 21 is hinged to the end edge of the top cover of the rice box 6, and slides within the concave grooves 20. The top of the rice box 6 has a feed inlet 40. When the drive rod 8 rises, it engages with the connecting rod 9. As the drive rod 8 rises further, it pushes the connecting rod 9, causing the lifting rack 22 to rise. The lifting rack 22 drives the rotating gear 23 to rotate clockwise, which in turn drives the bevel gear 24 to rotate clockwise. This causes the bevel gears 25, 3, 4, and 5 to rotate clockwise, further driving the active bevel gears 28 and 29 to rotate clockwise.Because the tooth surfaces of the first driving bevel gear 28 and the second driving bevel gear 29 face opposite directions, they ultimately drive the first driven bevel gear to rotate clockwise and the second driven bevel gear to rotate counterclockwise, thus opening the two door panels 11. This opening action of the rice hopper 1 is completed when the drive rod 8 rises, facilitating the subsequent unloading of rice into the rice hopper 1. After the drive rod 8 engages with the connecting rod 9, it drives the lifting rack 22 to slide and open the door panel 11 of the rice hopper 1. Since the rack 12 is slidably connected to the side of the rice box 6, when the rice box 6 is pushed closer to the rice hopper 1, the rack 12 remains stationary. When the rice box 6 moves, the driving gear 13, meshing with the rack 12, rotates clockwise. Driven gear 14 rotates clockwise, further driving driven gear 15 to rotate counterclockwise. Ultimately, both the driving and driven pulleys rotate counterclockwise, causing the rotating rod 16 inside the rice box 6 to rotate counterclockwise. This rotating rod 16 drives the lid 10 of the rice box 6 to rotate counterclockwise. The sliding groove 20 on the inner side of the lid 10 slides on the slider 21 on the top cover, flipping open the lid 10 of the rice box 6. Since a spring 18 is installed between short rod 17 and short rod 19, the spring 18 pulls the rotating rod 16 to rotate clockwise, ensuring that the lid 10 seals the rice box 6 when not under force. When the lid 10 of the rice box 6 flips, the rice inside the rice box 6 is immediately unloaded. The rice is automatically unloaded from the rice box 6 as it enters the rice silo 1. The rice silo 1 first opens its door panel 11, and then the rice box 6 flips open as it approaches the silo 1 to unload, ensuring the rice falls smoothly into the silo 1. The feed inlet 40 at the top of the silo 1 facilitates refilling the rice box 6 after unloading. The refilling process can employ conventional techniques, which will not be detailed here. By setting up a conveyor frame 2, a feeding frame 3, a discharging frame 4, and a loading frame 5, the rice is ensured to be cyclically collected into the rice silo 1. The number of conveyor frames 2, i.e., the number of rice silo sets, can be increased or decreased according to the factory size, making it suitable for different factories to control the floor space occupied by the entire process according to their own circumstances, demonstrating strong adaptability. Simultaneously, the rice is placed... The rice is transported in rice bins 6 to prevent spillage or contamination during transport. Furthermore, each row of rice bins contains multiple rice hoppers 1, which can be used to store rice of different qualities or specifications, effectively classifying and recycling the rice. Multiple rows of rice bins ensure that different specifications of rice can be simultaneously collected into the rice hoppers 1, improving work efficiency. A control system directs each rice bin 6 to its designated rice hopper 1 within the rice bin group, forming an efficient transport route and avoiding confusion. The drive assembly enables automatic opening of the rice hoppers 1 and rice bins 6, ensuring that rice from the rice bins 6 is smoothly fed into the rice hoppers 1, resulting in fully automatic unloading and improved work efficiency.

[0038] Furthermore, the drive assembly also includes two conveyor plates 32 located at the bottom of the rice container 6. A first conveyor roller 33 is rotatably connected to each conveyor plate 32. The rotation direction of the first conveyor roller 33 is perpendicular to the rotation direction of the rotating roller 7 in the conveyor frame 2. The conveyor plates 32 are respectively vertically fixed to the tops of the two vertical plates of the U-shaped slide plate 34. A rotating wheel 35 is rotatably connected to the outermost, more distant parts of the two vertical plates of the U-shaped slide plate 34. The rotating wheel 35 is slidably engaged in a second sliding groove 36 on the opposite side of the moving frame 38. The second sliding groove 36 is inverted L-shaped. The crossbar of the U-shaped slide plate 34 is hinged to the piston rod end of a first drive cylinder 37. The other end of the first drive cylinder 37 is hinged inside the moving frame 38. The upper end of the moving frame 38 is open. Slide rods 39 are fixed to the other two opposite outer sides of the moving frame 38. The slide rods 39 are slidably connected to the conveyor frame 2. The moving frame 38 above one slide rod 39 is connected to a first conveyor belt. The first conveyor belt is rotatably connected to the conveyor frame 2. When the first conveyor belt rotates, the moving frame 38... Driven by the control system, the moving frame 38 slides to the designated side of the rice bin 1. After the rice box 6 slides above the conveyor plate 32 and the drive rod 8 on the rice box 6 senses the signal from the connecting rod 9 on the rice bin 1, the piston rod of the drive cylinder 37 extends. The drive cylinder 37 first slides in the vertical groove of the slide 36, lifting the rice box 6. At this time, the drive rod 8 engages with the connecting rod 9. During the upward movement, the door panel 11 of the rice bin 1 is opened. As the drive cylinder 37 moves... As the stopper rod extends further, the slide plate 34 begins to slide in the transverse groove of the second slide 36, pushing the conveyor plate 32 closer to the rice bin 1. Since the drive rod 8 is engaged with the connecting rod 9 and the rack 12 is slidably connected to the rice box 6, when the rice box 6 approaches the rice bin 1, the rack 12 remains stationary, and the multiple gears meshing with the rack 12 rotate, completing the subsequent flipping of the rice box 6 cover 10, shortening the distance between the rice box 6 and the rice bin 1, and ensuring smooth unloading.

[0039] Furthermore, the rotating shaft located at the center of the drive gear 13 passes through the unloading plate 41 fixed inside the rice box 6. The unloading plate 41 is rotatably connected inside the rice box 6. The unloading plate 41 is hollow and has an extension plate 42 slidably connected inside. The other end of the extension plate 42 away from the unloading plate 41 is hinged and slidably connected to the inner side of the rice box 6 away from the box cover 10. As the rice box 6 gradually approaches the rice hopper 1, the drive gear 13 rotates clockwise, and the unloading plate 41 inside the rice box 6 also rotates clockwise. The unloading plate 41 forms an inclined shape, which is conducive to pouring the rice in the rice box 6 into the rice hopper 1 as much as possible, improving the cleanliness of rice unloading. The extension plate 42 is set in the unloading plate 41. The end of the extension plate 42 is hinged and slidably connected to the inner side of the rice box 6, which can ensure that the unloading plate 41 can be smoothly rotated counterclockwise.

[0040] Furthermore, a second driving gear 43 is rotatably connected below rack 12, and rack 12 meshes externally with driving gear 43. The toothed portion below rack 12 is longer than the toothed portion above rack 12. A second rack 44 is slidably connected to the side of rice box 6 below driving gear 43, and rack 44 meshes externally with driving gear 43. Rack 44 passes through one side of rice box 6 and is connected to the extension plate 45 at the bottom of rice box 6. The extension plate 45 is slidably connected to the bottom of rice box 6. In the empty slot, when the rice box 6 is close to the rice hopper 1, the drive gear 43 located below the rack 12 rotates counterclockwise. The rack 44, which is meshed below the drive gear 43, slides towards the rice hopper 1. The rack 44 then drives the extension plate 45 to extend out of the rice hopper. The extension plate 45 can penetrate into the rice hopper 1, which has already been opened, to provide a certain guiding effect for the unloading of the rice box 6 when it is opened, ensuring that all the rice falls into the rice hopper 1 and avoiding waste caused by rice being left outside.

[0041] Furthermore, both the feeding rack 3 and the discharging rack 4 are slidably connected to a reversing assembly. The reversing assembly includes a reversing plate 46, with a conveyor roller 47 rotatably connected to the reversing plate 46. The rotation direction of the conveyor roller 47 is perpendicular to the rotation direction of the rotating roller 7 in the feeding rack 3 and the discharging rack 4. The reversing plate 46 is vertically fixed to the piston rod of the driving cylinder 2. The other end of the driving cylinder 2 is fixed to a support plate 48, which is connected to a conveyor belt 2. The conveyor belt 2 is rotatably connected to the feeding rack 3 and the discharging rack 4. When it is determined that the rice box 6 needs to enter the conveyor rack 2 from the feeding rack 3, the control system drives the support plate 48 to slide to the designated area. When the rice... After box 6 slides onto reversing plate 46, the piston rod of drive cylinder 2 extends, lifting box 6. Under the rotation of conveying roller 47 or other drive device, box 6 is driven to vertically reverse onto conveyor frame 2. Similarly, when box 6 finishes unloading, as conveyor frame 2 enters discharge frame 4, the piston rod of drive cylinder 2 is extended to ensure that box 6 is smoothly connected to reversing plate 46. Then, the piston rod of drive cylinder 2 retracts, and box 6 falls onto discharge frame 4. Under the rotation of roller 7, it is pushed into loading frame 5, smoothly completing the unloading and loading of box 6. The process is carried out in an orderly manner, improving the work efficiency of the entire process.

[0042] Furthermore, it also includes a control system, which controls the movement of the moving frame 38 and the support plate 48 in the conveyor frame 2, the feeding frame 3 and the discharging frame 4, as well as the sensing of the drive rod 8 and the connecting rod 9. The drive cylinder 37 in each conveyor frame 2 is signal-connected to the rice bin 1 that needs to be fed in each row of rice bins. The drive cylinder 37, the drive rod 8 and the connecting rod 9 are signal-connected. By setting up the control system, the rice bin 1 and the rice box 6 structure, the rice in the rice box 6 is smoothly unloaded into the rice bin 1. The whole process is highly automated, which significantly improves the accuracy and efficiency of classification, summarization and recycling.

[0043] Furthermore, L-shaped baffles 49 are provided at the ends of the discharge rack 4 near the loading rack 5 and the loading rack 5 near the feeding rack 3. A first directional cylinder 50 and a second directional cylinder 51 are respectively installed in the baffles 49. The piston rod of the first directional cylinder 50 rotates in the same direction as the rotating roller 7 in the loading rack 5, and the piston rod of the second directional cylinder 51 rotates in the same direction as the rotating roller 7 in the feeding rack 3. When the unloaded rice box 6 moves from the discharge rack 4 to near the loading rack 5, the first directional cylinder 50 is activated, pushing the rice box 6 into the loading rack 5 with its posture unchanged. After sliding to the end of the loading rack 5, the rice box 6 can be loaded there. The loading process can use conventional techniques, which will not be detailed here. After loading is completed, the second directional cylinder 51 is activated to drive the rice box 6 into the feeding rack 3. At this time, the posture of the rice box 6 will not change, ensuring that the rice box 6 is unloaded smoothly.

[0044] Furthermore, a guide plate 52 is provided at the end of the conveyor frame 2 near the feed frame 3. The guide plate 52 ensures that the rice box 6 is in the correct posture when entering the conveyor frame 2, and ensures that the drive rod 8 and the connecting rod 9 are smoothly sensed and engaged.
