Description

Technical Field

[0001] The present invention relates to the technical field of in-and-out warehouse equipment, and particularly relates to a bulk material in-and-out warehouse equipment and its control system. Background Art

[0002] In the field of grain storage, due to its simple structure, relatively low cost, and easy operation, the flat warehouse is widely used for storing bulk materials (such as grains). The bulk material in-and-out warehouse equipment of the flat warehouse is the key to ensuring the efficient storage and transfer of grains.

[0003] Common bulk material inlet equipment for flat warehouses generally includes bucket elevators, belt conveyors, etc. The bucket elevator uses a surrounding bucket belt and is driven by a motor to lift the bulk material placed in the buckets from a low position to a high position, for example, from the ground to the top inlet of the flat warehouse. The belt conveyor relies on the motor to drive the belt to run. The bulk material is placed on the belt, and through the friction of the belt, it realizes horizontal or a certain inclined angle of transportation, and can transport the bulk material lifted by the bucket elevator to each inlet. The outlet equipment usually includes grain rakes, scraper conveyors, etc. The grain rake scrapes out the bulk material in the warehouse, and the scraper conveyor uses a chain to drive the scraper to transport the bulk material out of the warehouse along a set path.

[0004] Among these in-and-out warehouse equipment, the conveying equipment plays a core role. Taking the belt conveyor as an example, its working principle is based on friction drive. The motor drives the driving roller to rotate, and through the friction between the belt and the roller, the belt moves, thereby driving the materials on the belt to move forward. In some existing technologies, multiple belt conveyors can be detachably connected to each other to achieve the effect of transporting grains to a specified position in the granary, which has the advantages of high flexibility and fast conveying efficiency.

[0005] However, the existing conveying equipment has some obvious defects. In actual applications, when grains are transported on the belt conveyor, due to the friction between the baffle plates on both sides of the belt and the grains, especially during the long-term and large-scale transportation of grains, it will cause the breakage of grains. This not only reduces the quality of grains but also affects subsequent sales and processing. At the same time, during the in-and-out warehouse process, when the conveying line is long, the bulk materials often need to go through multiple lifting and throwing operations. For example, during inlet, if the distance between the grain throwing device and the bucket elevator is far, then multiple belt conveyors are needed for transportation between them, and the grains need to go through the process of lifting and falling between multiple belt conveyors. During this process, due to different movement trajectories and force conditions of grains with different particle sizes and densities, grain grading will occur. Grain grading will lead to uneven quality distribution of grains in the warehouse, increasing the difficulty of storage and management, and easily causing problems such as local heating and mildew, seriously affecting the storage safety of grains.

[0006] Based on the problems existing in the bulk material inlet and outlet equipment in the above prior art, the present invention aims to improve it. Through innovative structural design, the friction between the grain and the baffle on the conveyor belt is reduced, thereby reducing the breakage rate of the grain. At the same time, the conveying and inlet and outlet processes are optimized to avoid the grain grading phenomenon caused by multiple lifting and spilling processes, so as to improve the quality and efficiency of grain inlet and outlet and ensure the storage quality of grain. Summary of the Invention

[0007] The purpose of the present invention is to provide a bulk material inlet and outlet equipment and its control system, which can reduce the breakage rate of grain and reduce the grain grading phenomenon at the same time to ensure the storage quality of grain.

[0008] To achieve this purpose, the present invention adopts the following technical solutions:

[0009] Provide a bulk material inlet and outlet equipment, including a base, a frame body and a conveyor belt body. The frame body is vertically rotatably installed on the base, the bottom of the conveyor belt is fixedly connected to the top of the frame body, and it also includes a plurality of vibration components, a plurality of flipping components, a driving component, a leak-proof and dust-removing component and a positioning and connecting component. The positioning and connecting component is installed at the bottom of one end of the conveyor belt body and is used to connect the heads and tails of two conveyor belt bodies. The conveyor belt body includes a housing, a plurality of rollers and a conveyor belt. The plurality of rollers are horizontally spaced apart, and both sides of the rollers are rotatably connected to the inner walls of both sides of the housing. The rollers are cylindrical structures with a concave middle part. The conveyor belt is sleeved around the rollers. The top of the conveyor belt is an inclined surface structure with a concave middle part and fits with the periphery of the rollers. The conveyor belt is made of elastic material and is in a tensioned state. The vibration components and the flipping components are both installed on the conveyor belt body. The vibration components are used to drive one side of the conveyor belt to vibrate, and the flipping components are used to drive the other side of the conveyor belt to bounce. The driving component is installed on the housing and is used to drive the rollers to rotate and drive the vibration components and the flipping components to work. The leak-proof and dust-removing component is installed at the top of the other end of the conveyor belt body and is used to define the falling direction of the grain and remove dust.

[0010] The camming mechanism is configured to move the first end of the first and second end of the second wheels respectively in a direction of moving the camming wheel to move relative to the first wheel and the second wheel respectively.

When the first lever is located at the bottom of the turntable, the first lever is conflicted with the first knocking rod, and the second lever is located at the top of the turntable and separated from the second knocking rod.

[0012] Preferably, the drive assembly includes a motor, multiple sprockets, multiple drive gears and multiple transmission gears.

[0013] Preferably, the conveyor belt body also includes a pair of baffles, which are symmetrically distributed on both sides of the shell, and the bottom of the baffle is fixedly connected to the top of the shell. The two baffles are respectively fitted with both sides of the conveyor belt, and electric universal wheels are installed at the four corners of the bottom of the base. One end of the bottom of the frame passes through the base and is rotatably connected to it. The inner wall of the other end of the bottom of the frame is fixedly connected to a rotating shaft, and the top of the base is rotatably connected to a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is rotatably connected to the outer periphery of the rotating shaft.

[0014] Preferably, the leak-proof dust removal assembly includes a blanking hopper, a blanking pipe, a hollow column, a spiral blade, and a dust removal mechanism. Both sides of the bottom of the blanking hopper are fixedly connected to the top of one end of the housing. The blanking hopper is a hollow inverted quadrangular pyramid structure and its bottom is communicated with the top of the blanking pipe. The bottom of the blanking pipe is located on one side of the top of the conveyor belt close to the vibration assembly. The outer periphery of the spiral blade is fixedly connected to the inner wall of the blanking pipe. The outer periphery of the hollow column is fixedly connected to the inner wall of the spiral blade. The dust removal mechanism is installed on the housing and is used to remove dust from the grains.

[0015] Preferably, the dust removal mechanism includes a fan and an air duct. The bottom of the fan is fixedly connected to the top of the housing. One end of the air duct is communicated with the air inlet of the fan, and the other end of the air duct is communicated with the bottom of the hollow column. A plurality of sieve holes are spirally formed on the outer periphery of the hollow column. The height of the spiral blade near the center is higher than the height of its edge.

[0016] Preferably, the positioning and connecting assembly includes a universal joint, a fixing plate, a plurality of T-shaped rods, and a quick-release mechanism. The top of the universal joint is fixedly connected to the bottom of the housing. The bottom of the universal joint is fixedly connected to the top of the fixing plate. The plurality of T-shaped rods are arc-shaped and distributed at the bottom of the fixing plate. The top of the T-shaped rod is fixedly connected to the bottom of the fixing plate. The quick-release mechanism is installed on the blanking hopper, and the quick-release structure is used to quickly connect the fixing plate and the blanking hopper.

[0017] Preferably, the quick-release mechanism includes a pressing plate and a bolt. One side of the pressing plate is rotatably connected to the top of the blanking hopper. A semi-circular groove is formed at one end of the pressing plate and the top of the blanking hopper. The two semi-circular grooves are combined into an annular groove structure. The bottom of the T-shaped rod is slidably connected to the semi-circular groove and abuts against its inner wall. A convex block is fixedly connected to the other side of the pressing plate. The bottom of the bolt passes through the convex block and is threadedly connected to the blanking hopper.

[0018] The present invention also provides a control system for a bulk material inlet and outlet device, which includes the following steps. Step 1: Lift one end of the frame body through a hydraulic cylinder, adjust the conveyor belt body to an appropriate angle, then move the base to align one end of the conveyor belt body with the feeding hopper on another conveyor belt body, and connect the two conveyor belt bodies end to end through a positioning connection component. Step 2: Put grains on one side of the top of one end of the conveyor belt. A driving component is installed on the housing to drive the roller shaft to rotate, and at the same time drive the vibration component and the flipping component to work, so that the conveyor belt drives the grains to move and rise. Step 3: When the grains move to the top of the vibration component, the first knocking rod in the vibration component continuously knocks the top wall on one side of the conveyor belt upward during the movement of the conveyor belt, causing the grain particles to vibrate. And because the top of the conveyor belt is a sloped structure with the middle concave inward, as the conveyor belt moves, the grains gradually gather and flatten at the bottom of the conveyor belt, preventing collision and friction with the baffle. Step 4: When the grains move to the top of the flipping component, the second knocking rod in the flipping component quickly knocks the top wall on the other side of the conveyor belt upward during the movement of the conveyor belt, causing the grain particles to be lifted. Because one side of the conveyor belt is a sloped structure, the grain particles are flipped to the other side of the conveyor belt, thereby changing the position of the grain particles and preventing stratification. Step 5: The grains fall from the other end of the conveyor belt into the feeding hopper, and are accurately placed on one side of another conveyor belt through the anti-leakage and dust removal component, and the moderately doped dust is screened out during the falling process. Repeat the above operations to transport the grains to the designated position in the flat warehouse.

[0019] Advantages of the present invention:

[0020] 1. Through the coordinated work of the vibration component and the flipping component, the bulk materials on the conveyor belt are continuously vibrated and flipped, avoiding adhesion and grading of the bulk materials during transportation, ensuring smooth transportation of the bulk materials, and during transportation, dust removal of the bulk materials by the anti-leakage and dust removal component has the effect of preventing smoke and dust diffusion, improving the quality of inlet and outlet of the warehouse.

[0021] 2. The quick-release design of the positioning connection component in the present invention facilitates the assembly and adjustment of the equipment. Combined with the rotatable design of the frame body and the angle adjustment function of the hydraulic cylinder, the equipment can adapt to different scenarios and operating conditions. Whether it is a large-scale warehouse or a small flat warehouse, it can efficiently complete the task of inlet and outlet of bulk materials. Description of the drawings

[0048] As Figures 1 to 14 shown:

[0049] A bulk material inlet and outlet device, including a base 1, a frame 10 and a conveyor belt body 11. The frame 10 is vertically rotatably installed on the base 1. The bottom of the conveyor belt is fixedly connected to the top of the frame 10. It also includes a plurality of vibration components 2, a plurality of flipping components 3, a driving component 4, a leak-proof and dust-removing component 5 and a positioning and connecting component 6. The positioning and connecting component 6 is installed at the bottom of one end of the conveyor belt body 11. The positioning and connecting component 6 is used to connect the heads and tails of two conveyor belt bodies 11. The conveyor belt body 11 includes a housing 110, a plurality of rollers 111 and a conveyor belt 112. The plurality of rollers 111 are horizontally spaced apart. Both sides of the rollers 111 are rotatably connected to the inner walls of both sides of the housing 110. The rollers 111 are cylindrical structures with a concave middle part. The conveyor belt 112 is sleeved around the rollers 111. The top of the conveyor belt 112 is an inclined surface structure with a concave middle part and fits with the periphery of the rollers 111. The conveyor belt 112 is made of an elastic material and is in a tensioned state. The vibration components 2 and the flipping components 3 are both installed on the conveyor belt body 11. The vibration components 2 are used to drive one side of the conveyor belt 112 to vibrate, and the flipping components 3 are used to drive the other side of the conveyor belt 112 to bounce up. The driving component 4 is installed on the housing 110. The driving component 4 is used to drive the rollers 111 to rotate and drive the vibration components 2 and the flipping components 3 to work. The leak-proof and dust-removing component 5 is installed at the top of the other end of the conveyor belt body 11. The leak-proof and dust-removing component 5 is used to define the falling direction of the grain and remove dust.

[0050] This bulk material in-and-out bin equipment uses the base 1 as the support foundation. The frame 10 can rotate vertically on the base 1 to facilitate adjusting the working angle of the conveyor belt body 11. The rotation of the roller shaft 111 in the conveyor belt body 11 drives the running of the conveyor belt 112 to achieve the conveyance of bulk materials. A plurality of vibration components 2 and flipping components 3 are distributed on the conveyor belt body 11 and are uniformly driven by the drive component 4. They work together to perform vibration and flipping operations on the bulk materials on the conveyor belt 112. After the bulk materials are placed on the conveyor belt 112, they move to the top of the vibration component 2 along with the conveyor belt 112. At the same time, as the bulk materials continue to move forward, the vibration generated by the vibration component 2 causes the bulk materials to concentrate towards the middle depression of the conveyor belt 112, thereby preventing collision and friction between the bulk materials and the baffle 113 and flattening them to the bottom of the depression. Subsequently, the bulk materials pass through the top of the flipping component 3, and the upward impact force generated by the flipping component 3 flips the bulk materials from one side of the conveyor belt 112 to the other side, causing the positions of the bulk materials to be swapped. During the conveyance of the bulk materials, multiple vibrations and flips are performed to prevent the bulk materials from sticking and grading. The positioning and connecting component 6 is used to connect different conveyor belt bodies 11, facilitating extending or combining the conveying line according to the actual operation requirements. The leakage prevention and dust removal component 5 is installed at the top of one end of the conveyor belt body 11 to guide and dust-remove the bulk materials.

[0051] As Figures 1 to 11 shown:

[0052] The vibration component 2 includes a first knocking mechanism 20 and a first knocking rod 21. The top of the first knocking rod 21 is in mutual contact with the top wall of the conveyor belt 112. The flipping component 3 includes a second knocking mechanism 30 and a second knocking rod 31. The top of the second knocking rod 31 is in mutual contact with one side of the top wall of the conveyor belt 112. Both the first knocking mechanism 20 and the second knocking mechanism 30 include a bracket 200, a plurality of spur gears 202, a plurality of turntables 203, and a plurality of springs 204. The bracket 200 is fixedly connected to the inner wall of the housing 110. The spur gear 202 is rotatably connected to one side of the bracket 200. The turntable 203 is coaxially connected to one side of the spur gear 202. A through chute 201 is provided on one side of the bracket 200. One end of the spring 204 is fixedly connected to the top wall of the chute 201. One side of the first knocking rod 21 passes through the chute 201 and is vertically slidably connected thereto. The other end of the spring 204 is fixedly connected to the top of one side of the first knocking rod 21. A plurality of first shift rods 22 are fixedly connected to the periphery of the turntable 203 in the first knocking mechanism 20. The first shift rod 22 abuts against the first knocking rod 21. The second knocking rod 31 passes through the chute 201 and is vertically slidably connected thereto. The other end of the spring 204 is fixedly connected to the top of one side of the second knocking rod 31. A second shift rod 32 is fixedly connected to the periphery of the turntable 203 in the second knocking mechanism 30. The second shift rod 32 abuts against the second knocking rod 31.

[0053] A plurality of vibration components 2 are horizontally and spacedly distributed on one side of the housing 110, and a plurality of flipping components 3 are horizontally and spacedly distributed on the other side of the housing 110. The vibration components 2 and the flipping components 3 are staggered. The length of the first lever 22 is less than the length of the second lever 32. The plurality of first levers 22 are circumferentially arrayed around the turntable 203. When the first lever 22 is at the top of the turntable 203, the first lever 22 is separated from the first striking rod 21, and the second lever 32 is at the bottom of the turntable 203 and abuts against the second striking rod 31. When the first lever 22 is at the bottom of the turntable 203, the first lever 22 abuts against the first striking rod 21, and the second lever 32 is at the top of the turntable 203 and is separated from the second striking rod 31.

[0054] The driving component 4 includes a motor 40, a plurality of sprockets 41, a plurality of driving gears 42 and a plurality of transmission gears 43. One side of the motor 40 is fixedly connected to the housing 110. The output shaft of the motor 40 passes through the side wall of the housing 110 and is coaxially connected to one of the roller shafts 111. The sprocket 41 is coaxially connected to the outer periphery of one side of the roller shaft 111. The plurality of sprockets 41 are driven by a chain. The plurality of driving gears 42 are respectively coaxially connected to the outer peripheries of both sides of the plurality of roller shafts 111. The transmission gear 43 is rotatably connected to one side of the bracket 200. The transmission gear 43 meshes with the driving gear 42. The plurality of transmission gears 43 and the plurality of spur gears 202 are horizontally and alternately distributed at one end of the driving gear 42 and mesh with each other.

[0055] Power on the motor 40 to make it work. The output shaft of the motor 40 drives one of the roller shafts 111 to rotate. The sprocket 41 is coaxially connected to the outer periphery of one side of each roller shaft 111, and the transmission between the plurality of sprockets 41 is realized through a chain, thereby driving the other roller shafts 111 to rotate synchronously. While the roller shaft 111 is rotating, it drives the driving gear 42 to rotate, and through the meshing transmission between it and the transmission gear 43, and the meshing transmission between the transmission gear 43 and the spur gear 202, it drives the spur gear 202 and the turntable 203 to rotate. In this way, while the motor 40 drives the roller shaft 111 to rotate, it also drives the turntable 203 in the vibration component 2 and the flipping component 3 to rotate. And due to the position of each transmission gear 43 between two spur gears 202 and the position between the driving gear 42 and the spur gear 202, the driving gear and the spur gear 202 rotate in the same direction, enabling the conveyor belt body 11 to work synchronously with the vibration component 2 and the flipping component 3, thereby realizing the unified drive of the roller shaft 111, the vibration component 2 and the flipping component 3, and the turntable 203 in the vibration component 2 and the turntable 203 in the flipping component 3 rotate synchronously.

[0056] The first knocking mechanism 20 in the vibration assembly 2 has a rotating disk 203 coaxial with the spur gear 202. When the spur gear 202 rotates, the rotating disk 203 is driven to rotate, and the first lever 22 on the rotating disk 203 rotates along with the rotating disk 203. When the first lever 22 rotates to contact the first knocking rod 21, it pushes the first knocking rod 21 downward, stretching the spring 204. When the first lever 22 rotates away from the first knocking rod 21, the spring 204 rebounds, driving the first knocking rod 21 to bounce upward, thereby knocking on one side of the conveyor belt 112, causing it to vibrate. As the rotating disk 203 rotates, multiple first levers 22 distributed in a circle continuously drive the first knocking rod 21 to knock the conveyor belt 112 upward, causing it to vibrate continuously. In conjunction with the inclined surface structure on one side of the top of the conveyor belt 112, the bulk material is driven to vibrate and gradually move to the middle along the inclined surface at the top of the conveyor belt 112.

[0057] The working principle of the second knocking mechanism 30 of the flipping assembly 3 is similar. When the turntable 203 rotates and the second lever 32 contacts the second knocking lever 31, the second knocking lever 31 moves downward, compressing the spring 204. When it rotates away, the spring 204 rebounds, and the second knocking lever 31 bounces upward, bouncing the other side of the conveyor belt 112, and cooperating with the inclined structure on the other side of the top of the conveyor belt 112 to realize the flipping of the bulk material on the conveyor belt 112, and multiple second knocking levers 31 are located at the same position on the periphery of the turntable 203, so that multiple second knocking levers 31 knock upward from the bottom of the conveyor belt 112 at the same time, so that the impact force that drives the bulk material to flip is transmitted upward from different positions at the bottom at the same time, ensuring that the bulk material is flipped evenly.

[0058] Multiple vibration components 2 and flipping components 3 are staggered and evenly distributed on both sides of the shell 110, so that the bulk material moves from one side of the conveyor belt 112 to the other side and is flattened, and then flipped in the opposite direction to achieve position exchange. The first shift rod 22 and the second shift rod 32 have different contact states with the corresponding knocking rods when they are in different positions, thereby alternately vibrating and flipping the conveyor belt 112, so that the bulk material on the top of the conveyor belt 112 is regularly vibrated and flipped.

[0059] like Figures 1 to 7 As shown:

[0060] The conveyor belt body 11 also includes a pair of baffles 113, the two baffles 113 are symmetrically distributed on both sides of the shell 110, the bottom of the baffle 113 is fixedly connected to the top of the shell 110, and the two baffles 113 are respectively fitted with both sides of the conveyor belt 112. Electric-controlled universal wheels 12 are installed at the four corners of the bottom of the base 1. One end of the bottom of the frame 10 passes through the base 1 and is rotatably connected to it. The inner wall of the other end of the bottom of the frame 10 is fixedly connected to the rotating shaft 100. The top of the base 1 is rotatably connected to the hydraulic cylinder 13, and the telescopic end of the hydraulic cylinder 13 is rotatably connected to the outer periphery of the rotating shaft 100.

[0061] The baffle 113 is used to prevent the bulk material from spilling out of the conveyor belt 112. Due to the operation of the vibration assembly 2 and the design of the depression at the top of the conveyor belt 112, the bulk material is concentrated in the middle of the conveyor belt 112, preventing frictional collision between it and the baffle 113, which may cause breakage. Operate the hydraulic cylinder 13, and its telescopic end jacks up the rotating shaft 100, causing one end of the frame 10 to rotate upward. At the same time, the hydraulic cylinder 13 rotates between the rotating shaft 100 and the base 1, thereby adjusting the angle of the conveyor belt body 11. Subsequently, operate the electric control universal wheel 12 to turn and move the conveyor belt body 11 to a suitable position.

[0062] As Figures 1 to 14 shown:

[0063] The anti-leakage and dust removal assembly 5 includes a blanking hopper 50, a blanking pipe 51, a hollow column 52, a spiral blade 53 and a dust removal mechanism 54. Both sides of the bottom of the blanking hopper 50 are fixedly connected to the top of one end of the housing 110. The blanking hopper 50 is a hollow inverted quadrangular pyramid structure and its bottom is communicated with the top of the blanking pipe 51. The bottom of the blanking pipe 51 is located on one side of the top of the conveyor belt 112 close to the vibration assembly 2. The periphery of the spiral blade 53 is fixedly connected to the inner wall of the blanking pipe 51, and the periphery of the hollow column 52 is fixedly connected to the inner wall of the spiral blade 53. The dust removal mechanism 54 is installed on the housing 110 and is used to remove the dust in the grain.

[0064] The dust removal mechanism 54 includes a fan 540 and an air duct 541. The bottom of the fan 540 is fixedly connected to the top of the housing 110. One end of the air duct 541 is communicated with the air inlet of the fan 540, and the other end of the air duct 541 is communicated with the bottom of the hollow column 52. A plurality of sieve holes 520 are spirally formed on the periphery of the hollow column 52. The height of the spiral blade 53 near the center is higher than the height of its edge.

[0065] When the bulk material enters the blanking hopper 50, it slides down into the blanking pipe 51. When passing through the blanking pipe 51, the bulk material slides along the spiral blade 53. The spiral blade 53 plays a guiding and preliminary dispersing role for the bulk material and slows down the falling speed of the bulk material, preventing the excessive impact force during falling from causing the bulk material to break. Since the height of the spiral blade 53 near the center is higher than the height of its edge, combined with the centrifugal force generated during the process of the bulk material sliding down along the spiral blade 53, the bulk material slides down along the edge of the spiral blade 53, while the dust mixed in it is dispersed throughout the blanking pipe 51 due to its small mass. At this time, power on the fan 540 to generate suction, suck the dust in the bulk material through the sieve holes 520 of the hollow column 52 into the air duct 541 and discharge it, thereby realizing the dust removal of the bulk material and achieving the effect of preventing the diffusion of smoke and dust. At the same time, the bottom of the blanking pipe 51 is located on one side of the top of the conveyor belt 112 close to the vibration assembly 2, which can accurately convey the dust-removed and guided bulk material to one side of the conveyor belt 112 close to the vibration assembly 2.

[0066] AsFigures 1 to 13 As shown in the figure:

[0067] The positioning and connecting component 6 includes a universal joint 60, a fixing plate 61, a plurality of T-shaped rods 62 and a quick-release mechanism 63. The top of the universal joint 60 is fixedly connected to the bottom of the housing 110, the bottom of the universal joint 60 is fixedly connected to the top of the fixing plate 61, the plurality of T-shaped rods 62 are arc-shaped and distributed at the bottom of the fixing plate 61, the top of the T-shaped rod 62 is fixedly connected to the bottom of the fixing plate 61, and the quick-release mechanism 63 is installed on the blanking hopper 50. The quick-release structure is used to quickly connect the fixing plate 61 and the blanking hopper 50.

[0068] The quick-release mechanism 63 includes a pressing plate 630 and a bolt 632. One side of the pressing plate 630 is rotatably connected to the top of the blanking hopper 50. A semi-circular groove 500 is provided at one end of the pressing plate 630 and the top of the blanking hopper 50. The two semi-circular grooves 500 are combined into an annular groove structure. The bottom of the T-shaped rod 62 is slidably connected to the semi-circular groove 500 and abuts against its inner wall. A convex block 631 is fixedly connected to the other side of the pressing plate 630. The bottom of the bolt 632 passes through the convex block 631 and is threadedly connected to the blanking hopper 50.

[0069] Move the conveyor belt body 11 so that the two conveyor belt bodies 11 are connected end to end. Move the T-shaped rod 62 at the bottom of the conveyor belt body 11 into the semi-circular groove 500 on the blanking hopper 50 at the top of the other conveyor belt body 11. Then rotate the pressing plate 630 so that the semi-circular groove 500 on one side of it is combined with the semi-circular groove 500 on the blanking hopper 50 to form an annular groove. Then pass the bolt 632 downward through one side of the pressing plate 630 and threadedly connect it to the top of the blanking hopper 50, which can fix the pressing plate 630 and clamp the T-shaped rod 62 inside the arc-shaped groove. At this time, the T-shaped rod 62 can slide in a circular motion along the arc-shaped groove. Since the plurality of T-shaped rods 62 are arc-shaped, no matter how the angle between the two conveyor belt bodies 11 rotates, the fixing plate 61 is always located on the side of the conveyor belt body 11 away from the baffle 113 at the top, so that the blanking end of the conveyor belt body 11 at the top is always aligned with the center of the top of the blanking hopper 50 on the conveyor belt body 11 at the bottom. At the same time, the angle between the fixing plate 61 and the housing 110 can be adjusted through the universal joint 60, so that the positioning and connecting component 6 can adapt to the connection at different angles between the two conveyor belt bodies 11, realizing the quick connection and disassembly of the fixing plate 61 and the blanking hopper 50, and at the same time facilitating the connection and adjustment of different conveyor belt bodies 11.

[0070] This embodiment also provides a control system for a bulk material in-and-out bin device, including the following steps. Step 1: Lift one end of the frame 10 through the hydraulic cylinder 13 to adjust the conveyor belt body 11 to an appropriate angle. Then, move the base 1 to align one end of the conveyor belt body 11 with the feeding hopper 50 on another conveyor belt body 11, and connect the two conveyor belt bodies 11 end to end through the positioning connection assembly 6. Step 2: Put grains on one side of the top of one end of the conveyor belt 112. A driving assembly 4 is installed on the housing 110 to drive the roller 111 to rotate, and at the same time drive the vibration assembly 2 and the flipping assembly 3 to work, so that the conveyor belt 112 drives the grains to move and rise. Step 3: When the grains move to the top of the vibration assembly 2, the first knocking rod 21 in the vibration assembly 2 continuously knocks upward on the top wall of one side of the conveyor belt 112 during the movement of the conveyor belt 112, causing the grain particles to vibrate. And because the top of the conveyor belt 112 is a slope structure with the middle concave inward, as the conveyor belt 112 moves, the grains gradually gather and flatten at the bottom of the conveyor belt 112 to prevent collision and friction with the baffle 113. Step 4: When the grains move to the top of the flipping assembly 3, the second knocking rod 31 in the flipping assembly 3 quickly knocks upward on the top wall of the other side of the conveyor belt 112 during the movement of the conveyor belt 112, causing the grain particles to be lifted. Because one side of the conveyor belt 112 is a slope structure, the grain particles are flipped to the other side of the conveyor belt 112, thereby changing the positions of the grain particles to prevent stratification. Step 5: The grains fall from the other end of the conveyor belt 112 into the feeding hopper 50, and are accurately dropped onto one side of another conveyor belt 112 through the anti-leakage and dust-removing assembly 5, and the dust mixed in an appropriate amount is screened out during the falling process. Repeat the above operations to transport the grains to the designated position in the flat warehouse.
