Description

Technical Field

[0001] This invention relates to the field of material storage, and more specifically to a raw material anti-blocking device. Background Technology

[0002] A silo is a device used for storing and managing various materials. It is typically a closed container used to store powdery, granular, or liquid materials, such as grains, chemical raw materials, ores, and cement. The design and structure of a silo can be adjusted according to different materials and usage requirements. Generally, a silo has a top inlet and a bottom outlet for material entry and exit. Inside the silo, agitators, conveying equipment, and sensors can be installed to achieve material mixing, conveying, and monitoring. The main functions of a silo include storing materials, protecting materials from external environmental influences (such as moisture and pollution), controlling material flow and conveying, and monitoring material inventory and quality. Silos have wide applications in industrial production, agriculture, construction, and other fields.

[0003] For example, patent CN111977197B, published on March 1, 2022, discloses an anti-clogging rotating silo, comprising: a cylindrical silo body; a conical silo body located below the cylindrical silo body and having a discharge port at its bottom; a discharge gate located at the lower end of the conical silo body; and a support frame connected to the cylindrical silo body at its upper end. The conical silo body includes: several rotating silos with frustoconical inner circumferences pivotally connected vertically; a support frame connected to the lower end of the last rotating silo body; and a rotating silo body driving device. The frustoconical inner circumferences of the rotating silos form the inner circumference of the conical silo body. The cylindrical silo body is pivotally connected to the uppermost rotating conical silo section. This anti-clogging... In a rotating silo, when material adheres to the walls and causes blockage in the conical silo, the hydraulic motor of the rotating silo drive mechanism drives the main bodies of the two rotating silos in the rotating silo assembly to rotate in opposite directions via bevel gears, an upper bevel gear ring, and a lower bevel gear ring. Alternatively, the hydraulic motor of the rotating silo drive component drives the main bodies of the rotating silos to rotate via bevel gears and a lower bevel gear ring. The main bodies of the rotating silos can rotate one by one, or two adjacent main bodies can rotate in opposite directions. Furthermore, the forward and reverse rotation of the main bodies can be alternated, causing the material to detach from the rotating silo and prevent it from sticking to the walls; the anti-blocking effect is good.

[0004] The existing silos often have rod valves installed at the discharge port. Because of the holes and rough areas at the rod valve, the material accumulates and sticks due to increased friction when passing through the valve port. This causes the valve port diameter to decrease, affecting the material discharge speed of the silo. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material anti-blocking device to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A raw material anti-clogging device includes a hopper and a belt scale arranged at intervals. A square cone-shaped anti-clogging transition chamber, a material flow stabilizing component, and an integrated shut-off valve are installed sequentially from top to bottom at the lower opening of the hopper. There is a material discharge space between the bottom end of the integrated shut-off valve and the surface of the belt scale. The material flow stabilizing component includes a connecting sleeve, a blockage clearing component, and a driving unit. The connecting sleeve connects the lower opening of the anti-clogging transition chamber to the valve port of the integrated shut-off valve. The driving unit drives the blockage clearing component to pass through the valve port of the integrated shut-off valve to clear the blockage material at the valve port of the integrated shut-off valve.

[0008] The aforementioned connecting sleeve comprises, from top to bottom, a first cylinder, a second cylinder, and a third cylinder. The first cylinder is connected to the outlet of the anti-blockage transition chamber, and the third cylinder is connected to the valve port of the integrated shut-off valve. Stabilizing rings are installed at the connection points of the first and second cylinders and the second and third cylinders, respectively. The stabilizing rings are coaxially arranged with the connecting sleeve. The first and third cylinders are respectively fitted onto the two ends of the second cylinder. Both ends of the second cylinder are fitted with coaxially arranged drive gear sleeves. Multiple transmission gears are arranged on the outer side of both drive gear sleeves. The multiple transmission gears are arranged at intervals along the circumference of the stabilizing ring. The multiple transmission gears are connected to the stabilizing ring through shafts. The ends of the first and third cylinders near the second cylinder are fitted with mating gear sleeves, which are coaxially arranged with the connecting sleeve. The mating gear sleeves are fitted onto the outer side of the multiple transmission gears, and the mating gear sleeves mesh with the transmission gears.

[0009] As mentioned above, the side wall of the second cylinder is provided with an annular groove, which is coaxially arranged with the second cylinder. The annular groove divides the second cylinder into upper and lower parts. The unblocking component includes a drive ring block, which serves as a connecting part to connect the upper and lower parts of the second cylinder. The inner circular surface of the drive ring block is located inside the second cylinder. A scraper assembly is installed on the inner circular surface of the drive ring block, and the scraper assembly extends into the interior of the connecting sleeve.

[0010] The aforementioned scraper assembly includes a blade holder, which is divided into three sections along the vertical direction. The three blade holder sections are independently set and are located in the areas of the first cylinder, the second cylinder, and the third cylinder, respectively. Each of the three blade holder sections is equipped with a cleaning scraper.

[0011] As mentioned above, multiple tool holders are provided, and these multiple tool holders are spaced apart along the circumference of the drive ring block.

[0012] The aforementioned tool holder located in the third cylinder region includes a sliding sleeve. A slider is installed on the side wall of the sliding sleeve near the third cylinder. A guide groove is provided on the inner wall of the third cylinder. The slider is inserted into the guide groove. A cleaning scraper is installed on the side wall of the sliding sleeve away from the third cylinder. A drive rod is threadedly connected to the inner side of the sliding sleeve. Both ends of the drive rod pass through the sliding sleeve. The drive rod and the sliding sleeve are arranged coaxially. The drive rod is rotatably connected to the third cylinder. A drive gear is installed at the end of the drive rod near the second cylinder. The drive gear and the drive rod are arranged coaxially. An arc-shaped drive rack is installed at the end of the tool holder located in the second cylinder near the third cylinder. The drive rack meshes with the drive gear. The drive rod rotates around its own axis.

[0013] As described above, a rotating ring is fixedly installed on the inner wall of the third cylinder. The rotating ring is sleeved on the outside of the drive rod. An annular groove is opened on the inner circular surface of the rotating ring. Multiple inserts are installed on the side wall of the drive rod. The multiple inserts are arranged at intervals along the circumference of the drive rod. The end of the multiple inserts away from the drive rod is inserted into the annular groove.

[0014] As mentioned above, tapered blocks are fitted at both ends of the sliding sleeve, and the larger diameter end of the tapered block is connected to the sliding sleeve.

[0015] The aforementioned unblocking scraper located inside the third cylinder includes a fixed section and a movable section. The fixed section is fixedly installed on the side wall of the sliding sleeve, and one end of the movable section is rotatably connected to the fixed section through a reset torsion spring.

[0016] The aforementioned drive unit includes a frame and a drive motor. The frame is placed on the ground, and the drive motor is mounted on the frame. A power gear is mounted on the output shaft of the drive motor. The power gear and the output shaft of the drive motor are coaxially arranged. The power gear is externally meshed with a drive ring gear, which is mounted on the outer side wall of the drive ring block.

[0017] The beneficial effects of the present invention are as follows: In the above technical solution, the plug provided by the present invention can pass through the valve port of the integrated shut-off valve. When material blockage occurs at the valve port of the integrated shut-off valve, the unblocking component passes through the valve port of the integrated shut-off valve under the action of the driving unit, and conducts the accumulated material in the valve port area of ​​the integrated shut-off valve. The conducted material falls onto the surface of the belt scale, thus clearing the valve port of the integrated shut-off valve and avoiding the accumulation and hanging of material at the valve port of the integrated shut-off valve, which would affect the material discharge speed of the silo.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 - Appendix Figure 9 The present invention will be described in further detail below.

[0031] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "degree," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] This invention provides a raw material anti-clogging device, comprising a hopper 1 and a belt scale 2 arranged vertically at intervals. A square-pyramid-shaped anti-clogging transition chamber 3, a material flow stabilizing component 4, and an integrated shut-off valve 5 are sequentially installed from top to bottom at the lower opening of the hopper 1. A discharge space 6 exists between the bottom end of the integrated shut-off valve 5 and the surface of the belt scale 2. When material from the hopper 1 falls onto the surface of the belt scale 2 after passing through the anti-clogging transition chamber 3, the material flow stabilizing component 4, and the integrated shut-off valve 5, the position of the material is the discharge space 6. The larger the discharge space 6, the better the performance of the belt scale. The more material conveyed on scale 2 at one time, the more material is conveyed. The material flow stabilization component 4 includes a connecting sleeve 41, a blockage clearing component 42, and a drive unit 43. The connecting sleeve 41 connects the lower opening of the anti-blockage transition chamber 3 to the valve port of the integrated shut-off valve 5. The drive unit 43 includes a linear telescopic rod. The linear telescopic rod is connected to the inner wall of the connecting sleeve 41 through a conical cover. The telescopic end of the linear telescopic rod is connected to the blockage clearing component 42. The linear telescopic rod drives the blockage clearing component 42 to pass through the valve port of the integrated shut-off valve 5 from top to bottom, clearing the blockage material at the valve port of the integrated shut-off valve 5.

[0033] Specifically, the material inside silo 1 enters the anti-blockage transition chamber 3 and then enters the connecting sleeve 41 of the material flow stabilization component 4. Subsequently, the material passes through the valve port of the integrated shut-off valve 5 and falls into the discharge space 6 on the belt scale 2. The belt scale 2 then transports the material in the discharge space 6, completing the material conveying operation inside silo 1. When a blockage occurs at the valve port of the integrated shut-off valve 5, affecting the normal discharge of material inside silo 1, the belt scale 2 sends an electrical signal to the drive unit 43, causing the drive unit 43 to start working. The linear telescopic rod of the drive unit 43 begins to extend, driving the unblocking component 42 to move towards the valve port of the integrated shut-off valve 5 until the unblocking component 42 passes through the valve port of the integrated shut-off valve 5, thus clearing the blockage at the valve port of the integrated shut-off valve 5. When the blockage is cleared, the linear telescopic rod of the drive unit 43 automatically stops, and silo 1 discharges material normally. The entire process takes about 10 seconds, and the equipment does not require on-site operation or maintenance; it operates fully automatically.

[0034] It should be noted that, in this embodiment, the upper inlet size of the square cone-shaped anti-blockage transition chamber 3 is preferably 2400x2000mm, the outlet size is preferably 1800x1800mm, the height is preferably 1100mm, and the material is preferably a composite structure of 10mm carbon steel + 3mm stainless steel. The inlet size of the connecting sleeve 41 of the material flow stabilizing component 4 is 1800x1800mm, the diameter of the outlet size of the connecting sleeve 41 of the material flow stabilizing component 4 is 760mm, and the height of the connecting sleeve 41 of the material flow stabilizing component 4 is 1800mm.

[0035] Furthermore, when the valve port of the integrated shut-off valve 5 is blocked by material, the linear telescopic rod of the drive unit 43 begins to extend, driving the unblocking component 42 to pass through the valve port of the integrated shut-off valve 5 from top to bottom, clearing the blockage material at the valve port of the integrated shut-off valve 5, so that the valve port of the integrated shut-off valve 5 is open, and the material in the anti-blockage transition chamber 3 can normally enter the discharge space 6 on the surface of the belt scale 2 through the connecting sleeve 41, improving the discharge efficiency of the material in the silo 1. In this embodiment, when the material conveyed by the belt scale 2 decreases, the belt scale 2 sends an electrical signal to the drive unit 43 to drive the unblocking component 42 to move. This technology is existing technology and will not be described in detail here.

[0036] In this embodiment, the bottom shape of the unblocking component 42 is adapted to the valve port of the integrated shut-off valve 5. The top of the unblocking component 42 is connected to the telescopic end of the linear telescopic rod. The top of the unblocking component 42 is conical, and a conical cover is provided above the drive part 43. All of these are to prevent material from accumulating above the drive part 43 and the unblocking component 42.

[0037] In another embodiment of the present invention, the drive unit 43 includes a frame 434 and a drive motor 431. The frame 434 is placed on the ground, and the drive motor 431 is mounted on the frame 434. A power gear 432 is mounted on the output shaft of the drive motor 431. The power gear 432 and the output shaft of the drive motor 431 are coaxially arranged. The external connecting sleeve 41 includes a first cylinder 411, a second cylinder 412, and a third cylinder 413 from top to bottom. An annular groove 49 is formed on the side wall of the second cylinder 412. The annular groove 49 and the second cylinder are connected. The second cylinder 412 is coaxially arranged, and the annular groove 49 divides the second cylinder 412 into upper and lower parts. The unblocking component 42 includes a drive ring block 421, which serves as a connecting part to connect the upper and lower parts of the second cylinder 412. The drive ring block 421 is fixedly connected to the upper and lower parts of the second cylinder 412. The power gear 432 is externally meshed with drive ring teeth 433, which are installed on the outer side wall of the drive ring block 421. The first cylinder 411 is connected to the outlet of the anti-blocking transition chamber 3, and the outlet of the anti-blocking transition chamber 3 is circular. The outlet of the ferry 3 is adapted to the inlet size of the first cylinder 411. The third cylinder 413 is connected to the valve port of the integrated shut-off valve 5. Stabilizing rings 44 are installed at the connection points of the first cylinder 411 and the second cylinder 412, and at the connection points of the second cylinder 412 and the third cylinder 413. The stabilizing rings 44 are coaxially arranged with the connecting sleeve 41 and are fixedly connected to the frame 434. The first cylinder 411 and the third cylinder 413 are respectively fitted onto both ends of the second cylinder 412. Both ends of the second cylinder 412 are equipped with coaxially arranged... The drive sleeve 45 has multiple transmission gears 46 arranged in a circumferential array on its outer side. The multiple transmission gears 46 are arranged at intervals along the circumferential direction of the stabilizing ring 44. The multiple transmission gears 46 are connected to the stabilizing ring 44 through the shaft 47. The end of the first cylinder 411 and the third cylinder 413 near the second cylinder 412 is equipped with a mating sleeve 48. The mating sleeve 48 is arranged coaxially with the connecting sleeve 41. The mating sleeve 48 is sleeved on the outside of the multiple transmission gears 46, and the mating sleeve 48 meshes with the transmission gears 46.

[0038] Specifically, when the valve port of the integrated shut-off valve 5 becomes blocked, the amount of material falling into the discharge space 6 on the belt scale 2 decreases, resulting in a reduction in the material conveyed by the belt scale 2. At this time, the belt scale 2 sends an electrical signal to the drive unit 43, and the drive motor 431 starts to work. The drive motor 431 drives the power gear 432 to rotate around its own axis. When the power gear 432 rotates, it meshes with the drive ring gear 433, causing the drive ring gear 433 to rotate around its own axis. The drive ring gear 433 drives the drive ring block 421 to rotate synchronously. As the drive ring block 421 rotates, it causes the second cylinder 412 to rotate around its own axis (in this embodiment, the second cylinder 412 rotates clockwise). During this rotation, the second cylinder 412 causes the drive gear sleeves 45 on both sides to rotate synchronously. The drive gear sleeves 45 mesh with the outer transmission gear 46 during their rotation, causing the transmission gear 46 to rotate around the axis of the shaft 47. The transmission gear 46 rotates counterclockwise (at this time, the transmission gear 46 rotates counterclockwise), and the transmission gear 46 meshes with the outer mating gear sleeve 48, causing the mating gear sleeve 48 to rotate around its own axis, thereby driving the first cylinder 411 and the third cylinder 413 to also rotate around their own axes (because the teeth on the mating gear sleeve 48 exist on the inner circular surface of the mating gear sleeve 48, similar to planetary gears, at this time the first cylinder 411 and the third cylinder 413 rotate counterclockwise). At this time, the first cylinder 41... The rotation direction of the first cylinder 411 is the same as that of the third cylinder 413, but the rotation direction of the first cylinder 411 and the third cylinder 413 is opposite to that of the second cylinder 412. This causes the first cylinder 411, the second cylinder 412 and the third cylinder 413 to rotate relative to each other, so that the material arched on the inner wall of the connecting sleeve 41 moves relative to it. The material that helps the arched material slides down and falls into the discharge space 6 on the belt scale 2 through the valve port of the integrated shut-off valve 5, thereby clearing the blockage of the hopper 1.

[0039] The inner circular surface of the drive ring block 421 is located inside the second cylinder 412, and the inner circular surface of the drive ring block 421 is flush with the inner wall surface of the second cylinder 412. A scraper assembly 40 is installed on the inner circular surface of the drive ring block 421. The scraper assembly 40 extends into the interior of the connecting sleeve 41. The scraper assembly 40 includes a blade holder 401, which is divided into three sections in the vertical direction. The three sections of the blade holder 401 are independently arranged and are located in the first cylinder 411. The area between the second cylinder 412 and the third cylinder 413, and the first end knife holder 401 is fixedly connected to the inner wall of the first cylinder 411, the second section knife holder 401 is fixedly connected to the inner wall of the drive ring block 421 on the second cylinder 412, and the third section knife holder 401 is fixedly connected to the inner wall of the third cylinder. The length direction of the three sections of the knife holder 401 is consistent with the inclined trajectory of the inner wall surface of the connecting sleeve 41, and each of the three sections of the knife holder 401 is equipped with a cleaning scraper 402.

[0040] Specifically, when the drive ring block 421 drives the second cylinder 412 to rotate around its own axis under the action of the drive unit 43, the scraper assembly 40 also rotates synchronously with the second cylinder 412. Thus, when the first cylinder 411, the second cylinder 412 and the third cylinder 413 rotate relative to each other, the knife holders 401 located in the first cylinder 411, the second cylinder 412 and the third cylinder 413 also rotate relative to each other. The knife holders 401 located in the first cylinder 411, the second cylinder 412 and the third cylinder 413 drive the unblocking scrapers 402 on them to rotate relative to each other. The unblocking scrapers 402 located in the first cylinder 411, the second cylinder 412 and the third cylinder 413 move the arched material in the first cylinder 411, the second cylinder 412 and the third cylinder 413, and disperse the arched material in the connecting sleeve 41, so as to avoid material blockage inside the connecting sleeve 41 and affect the normal discharge of the hopper 1.

[0041] Multiple tool holders 401 are provided, and the multiple tool holders 401 are arranged at circumferential intervals along the drive ring block 421.

[0042] Specifically, by setting multiple knife holders 401 inside the connecting sleeve 41, and arranging the multiple knife holders 401 at intervals along the circumference of the drive ring block 421, when the drive ring block 421 drives the second cylinder 412 to rotate around its own axis under the action of the drive unit 43, the unblocking scrapers 402 on the multiple knife holders 401 simultaneously move the material inside the connecting sleeve 41, thereby improving the dispersing effect of the arched material inside the connecting sleeve 41 and further improving the unblocking capability of the silo 1.

[0043] The knife holder 401 located in the third cylinder 413 region includes a sliding sleeve 403. A cleaning scraper 402 is fixedly mounted on the sliding sleeve 403. Multiple placement slots 4024 are also provided on the side of the cleaning scraper 402 away from the inner wall of the third cylinder 413. These placement slots 4024 are spaced apart along the length of the cleaning scraper 402. A pusher block 4025 is rotatably mounted inside each placement slot 4024. The end of the pusher block 4025 away from the placement slot 4024 is deflected towards the valve port of the integrated shut-off valve 5. An adjusting torsion spring 4026 is connected between the pusher block 4025 and the placement slot 4024. It should be noted that when the pusher block 4025 is compressed into the placement slot 4024 by the material, the pusher... The end of block 4025 near the valve port of the integrated shut-off valve 5 remains inclined to the placement groove 4024, meaning the pusher block 4025 and the unblocking scraper 402 are arranged at an angle. A slider 404 is installed on the side wall of the sliding sleeve 403 near the third cylinder 413. A guide groove 414 is provided on the inner wall of the third cylinder 413. The end of the guide groove 414 near the integrated shut-off valve 5 has a downward-sloping surface at its connection with the third cylinder 413. This means the bottom of the guide groove 414 is inclined downwards towards the inside of the third cylinder 413, allowing material inside the guide groove 414 to flow along the inclined surface at the bottom of the guide groove 414 into the third cylinder 413, preventing material from flowing into the third cylinder 413. When material accumulates inside, the slider 404 is inserted into the guide groove 414. The unblocking scraper 402 is installed on the side wall of the sliding sleeve 403 away from the third cylinder 413. A drive rod 405 is threadedly connected to the inner side of the sliding sleeve 403. Both ends of the drive rod 405 pass through the sliding sleeve 403. The drive rod 405 and the sliding sleeve 403 are arranged coaxially. The drive rod 405 is rotatably connected to the third cylinder 413. A rotating ring 415 is fixedly installed on the inner wall of the third cylinder 413. The rotating ring 415 is sleeved on the outer side of the drive rod 405. An annular groove 416 is opened on the inner circular surface of the rotating ring 415. Multiple inserts 417 are installed on the side wall of the drive rod 405. The multiple inserts 417 move along the drive rod 405. The inserts are arranged circumferentially, with one end of the insert 417 away from the drive rod 405 inserted into the annular groove 416. A drive gear 406 is installed at the end of the drive rod 405 near the second cylinder 412. The drive gear 406 is coaxially arranged with the drive rod 405. An arc-shaped drive rack 407 is installed at the end of the tool holder 401 located in the second cylinder 412 near the third cylinder 413. The drive rack 407 meshes with the drive gear 406. At this time, the insert 417 slides along the groove of the annular groove 416, and the drive rod 405 rotates around its own axis. There is a gap between the teeth of the drive gear 406 and the drive rack 407. The drive gear 406 performs coarse transmission under the drive of the drive rack 407.

[0044] Specifically, when the driving ring block 421 drives the second cylinder 412 to rotate around its own axis under the action of the driving unit 43, the tool holder 401 connected to the second cylinder 412 rotates synchronously with the second cylinder 412. Under the action of the driving unit 43, the third cylinder 413 rotates in the opposite direction to the second cylinder 412. Therefore, when the second section of the tool holder 401 connected to the second cylinder 412 rotates synchronously with the second cylinder 412, the third section of the tool holder 401 connected to the third cylinder 413 also rotates synchronously with the third cylinder 413. When the second section of the tool holder 401 connected to the second cylinder 412 comes into contact with the third section of the tool holder 401 connected to the third cylinder 413, the tool holder on the second section of the tool holder 401... The arc-shaped drive rack 407 meshes with the drive gear 406 on the third-section tool holder 401, causing the drive gear 406 to rotate around its own axis. The drive gear 406 drives the drive rod 405 to rotate synchronously, and the drive rod 405 rotates around its own axis. At this time, the insert block 417 slides along the groove of the annular groove 416, and the drive rod 405 engages with the outer sliding sleeve 403 through a thread. Under the action of the slider 404, the sliding sleeve 403 moves along the groove of the guide groove 414 toward the valve port of the integrated shut-off valve 5, thereby driving the unblocking scraper 402 to move synchronously toward the valve port of the integrated shut-off valve 5, so that the unblocking scraper 402 passes through the valve port of the integrated shut-off valve 5, completing the unblocking of the integrated shut-off valve. The unblocking treatment of the valve port of the shut-off valve 5 improves the anti-clogging ability of the hopper 1. After the unblocking treatment of the valve port of the integrated shut-off valve 5 is completed, the drive motor 431 rotates in the opposite direction, driving the slider 404 to move along the groove of the guide groove 414 away from the valve port of the integrated shut-off valve 5. This drives the unblocking scraper 402 to move synchronously away from the valve port of the integrated shut-off valve 5. The unblocking scraper 402 leaves the valve port of the integrated shut-off valve 5, completing the reset action of the unblocking scraper 402. It should also be noted that in this embodiment, the size of the unblocking scraper 402 is smaller than the size of the valve port of the integrated shut-off valve 5. Therefore, when the connecting sleeve 41 does not rotate, the inner wall of the connecting sleeve 41... Because of its small size, the cleaning scraper 402 reduces its obstruction effect on the flow of material inside the connecting sleeve 41, preventing material accumulation and blockage due to the presence of the cleaning scraper 402. Conversely, when blockage occurs at the valve port of the integrated shut-off valve 5, the pusher block 4025 is compressed by the stacked material inside the connecting sleeve 41 and stored in the placement groove 4024 of the cleaning scraper 402. At this time, there is an angle between the end of the pusher block 4025 near the valve port of the integrated shut-off valve 5 and the cleaning scraper 402. Subsequently, as the sliding sleeve 403 follows the slider 404, it moves along the groove of the guide groove 414 toward the valve port of the integrated shut-off valve 5.Obstructed by the material below the pusher block 4025, the end of the pusher block 4025 closest to the integrated shut-off valve 5 is driven to deflect away from the integrated shut-off valve 5, increasing the radial area of ​​the pusher block 4025 on the connecting sleeve 41. Furthermore, as the sliding sleeve 403 follows the slider 404 along the groove of the guide groove 414 towards the valve port of the integrated shut-off valve 5, the unfolded pusher block 4025 pushes the material blocking the valve port of the integrated shut-off valve 5 out of the valve port and onto the surface of the belt scale 2, completing the unblocking process at the valve port of the integrated shut-off valve 5. Moreover, when the material compaction is high, as the pusher block... As the material block 4025 moves towards the valve port of the integrated shut-off valve 5, only a portion of the material can be pushed out of the connecting sleeve 41. The area where the material is pushed out forms a cavity. At this time, as the third cylinder 413 and the second cylinder 412 rotate relative to each other, the pushing block 4025 rotates synchronously with the third cylinder 413. The pushing block 4025 pushes the material around the compacted material towards the adjacent cavity, causing the material in contact with the wall of the connecting sleeve 41 to collapse, reducing the contact area between the compacted material and the connecting sleeve 41. This allows the compacted material to continue moving towards the surface of the belt scale 2 below, thus clearing the valve port of the integrated shut-off valve 5.

[0045] It should be further explained that in this embodiment, the inner wall of the annular groove 416 is made of rubber, meaning that the inner wall of the annular groove 416 will deform when compressed. Furthermore, the end of the annular groove 416 near the integrated shut-off valve 5 is inclined downwards towards the axis of the connecting sleeve 41, allowing material to slide directly into the connecting sleeve 41 along the end of the annular groove 416 near the integrated shut-off valve 5. When the annular groove 416 is blocked by material, as the insert 417 rotates along the annular groove 416, the insert 417 compresses the material, causing deformation of the inner wall of the annular groove 416. This causes the opening size of the annular groove 416 to increase, making it easier for the insert block 417 to rotate normally along the annular groove 416. This prevents material from clogging the annular groove 416 and causing transmission jamming. When the deformed annular groove 416 returns to its original position, it undergoes elastic deformation, causing the material in contact with the inner wall of the annular groove 416 to shake synchronously. This promotes the material to detach from the annular groove 416, causing the material in the annular groove 416 to change from an initial tight state to a loose rotating state. When there is no material accumulation inside the connecting sleeve 41, the loose material slides from below the annular groove 416 into the inside of the connecting sleeve 41.

[0046] Both ends of the sliding sleeve 403 are fitted with tapered blocks 408. The larger diameter end of the tapered block 408 is connected to the sliding sleeve 403, that is, the tip of the tapered block 408 is set in a direction away from the sliding sleeve 403.

[0047] It should be noted that when the sliding sleeve 403 moves along the axial direction of the drive rod 405, the tips of the conical blocks 408 at both ends of the sliding sleeve 403 can break through the material in the moving direction of the sliding sleeve 403, reduce the obstruction of the material to the sliding sleeve 403, and improve the smoothness of the sliding sleeve 403 moving along the axial direction of the drive rod 405 with the unblocking scraper 402.

[0048] The unblocking scraper 402 located in the third cylinder 413 includes a fixed section 4021 and a movable section 4022. The fixed section 4021 is fixedly installed on the side wall of the sliding sleeve 403. One end of the movable section 4022 is rotatably connected to the fixed section 4021 through a rotating shaft and a return torsion spring 4023. When the fixed section 4021 and the movable section 4022 are coaxial, the return torsion spring 4023 is in a deformed state and accumulates elastic potential energy. When the return torsion spring 4023 is not under force, the axial direction of the fixed section 4021 intersects the axial direction of the movable section 4022, and the movable section 4022 is in contact with the surface of the valve port of the integrated shut-off valve 5.

[0049] Specifically, when multiple unblocking scrapers 402 move along the axis of the drive rod 405 towards the valve port of the integrated shut-off valve 5 under the action of the drive unit 43, the fixed section 4021 and the movable section 4022 are coaxially arranged, and the reset torsion spring 4023 is in a deformed state, accumulating elastic potential energy. When the movable section 4022 of the unblocking scraper 402 extends into the valve port of the integrated shut-off valve 5, the side of the movable section 4022 near the inner wall of the valve port of the integrated shut-off valve 5 loses support, and the reset torsion spring 4023 releases the accumulated elastic potential energy. The reset torsion spring 4023 deflects the movable section 4022 towards the inner wall of the valve port of the integrated shut-off valve 5, so that the movable section 4022 of the unblocking scraper 402 hits the inner wall of the valve port of the integrated shut-off valve 5, generating vibration, which helps the material arched at the valve port of the integrated shut-off valve 5 to disperse, thereby achieving the purpose of preventing blockage in the silo 1.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
