Description

Technical Field

[0001] This invention relates to the field of screw conveyor technology, and in particular to an anti-clogging screw conveyor device with online visual monitoring function. Background Technology

[0002] Gypsum powder is a raw material for the production of autoclaved aerated concrete (AAC) self-insulating blocks and autoclaved lightweight AAC partitions. The flexible hose screw conveyor is used to transport gypsum powder from the storage silo to the batching section in a closed manner, realizing continuous feeding and preventing dust spillage. The equipment mainly consists of a drive motor, a flexible spiral spring, a conveying hose, an inlet, and an outlet. During operation, gypsum powder falls into the hose through the inlet. The drive motor drives the flexible spiral spring to rotate, continuously pushing the gypsum powder along the axial direction of the hose. Finally, it is evenly discharged from the outlet to the downstream equipment, completing the automated material conveying.

[0003] The prior art discloses a flexible hose spiral conveying device with the publication number CN212798330U. This technical solution combines the fixing method with the installation structure, which extends the service life of the spring, simplifies the installation process, prevents the complex operation of frequently replacing and installing springs, and improves the safety of use and operation.

[0004] While the aforementioned structure enhances the service life of the flexible screw conveyor, in actual use, the conveying length of a single device is limited. When the distance between the storage silo and the batching section is far, it is impossible to rely on a single device to complete the entire material supply process. Multiple devices need to be spliced ​​and connected in series. Existing splicing methods mostly use fixed flange connections, which are cumbersome to disassemble and assemble, time-consuming to connect, and difficult to guarantee the sealing and coaxiality of the connection. This leads to frequent powder leakage and material accumulation, which not only affects the conveying efficiency but also increases the difficulty of equipment maintenance and the risk of dust pollution.

[0005] Therefore, an anti-clogging spiral conveyor with online visual monitoring function is proposed to solve the above problems. Summary of the Invention

[0006] To address the technical problem that existing flexible hose screw conveyors cannot be quickly assembled over long distances, this invention provides an anti-clogging screw conveyor device with online visual monitoring capabilities.

[0007] The technical solutions provided by the embodiments of the present invention are as follows: This invention provides an anti-clogging screw conveyor with online visual monitoring function, comprising a drive motor, a conveying hose, a feed hopper, a discharge frame, and a fixing frame. A pair of fixing frames are provided, with a rotating rod rotatably connected to the top of the two fixing frames. The discharge frame is fixedly connected to the top of the rotating rod. The feed hopper is fixedly connected to and communicates with the feed end of the conveying hose. A main ring is provided on the side wall of the discharge frame, and a docking frame is rotatably and sealingly connected to the side wall of the main ring. A pair of T-slots are provided on the side wall of the docking frame. A pair of T-shaped blocks are fixedly connected to the outer wall of the feed hopper. U-shaped frames are fixedly connected to both sides of the outer wall of the feed hopper. A pair of hinge seats are fixedly connected to both sides of the outer wall of the docking frame. A T-shaped screw is rotatably connected to the inner side of the hinge seat. A locking ring is threaded to the side end of the T-shaped screw. When docking, the T-shaped block on the other feed hopper is inserted into the T-shaped groove. Then, the T-shaped screw is flipped and inserted into the U-shaped frame. The locking ring is tightened to make the discharge frame tightly connected to the feed hopper. An adjustment mechanism for adjusting the angle of the docking frame is also provided. When connecting two flexible screw conveyors, align the T-block on the feed hopper of the downstream equipment with the T-slot of the upstream feed hopper, then flip the T-screw to engage it in the U-shaped frame, and tighten the locking ring to ensure a tight fit between the discharge frame and the feed hopper. This completes the connection, enabling quick assembly of two flexible screw conveyors, significantly reducing downtime during equipment maintenance and material changes, and improving production continuity. Furthermore, based on its modular design, the number of units can be flexibly increased or decreased according to the actual conveying distance, adapting to the material supply needs of production lines of different sizes and reducing equipment configuration costs.

[0008] In the above technical solution, a flexible helical spring is further provided inside the conveying hose. The drive motor is fixedly connected to the rear side of the discharge frame. The discharge end of the conveying hose is fixedly connected to the bottom end of the discharge frame. A transmission mechanism is provided on the discharge frame. The drive motor is connected to the flexible helical spring through the transmission mechanism to drive the flexible helical spring to rotate. Through the setting of the drive motor and the transmission mechanism, the output power of the drive motor is transmitted to the drive end of the flexible helical spring through the transmission mechanism, thereby driving the flexible helical spring to rotate inside the conveying hose, continuously pushing the gypsum powder falling into the feed hopper along the axial direction of the hose, and finally discharging it from the bottom end of the discharge frame.

[0009] In the above technical solution, the adjusting mechanism further includes an adjusting motor, a gear, and a gear ring. A fixed ring is fixedly connected to the outer wall of the discharge frame. The main ring is rotatably and sealed to the outer wall of the fixed ring. The gear ring is fixedly connected to the outer wall of the main ring. A support is fixedly connected to the top of the rotating rod. The adjusting motor is fixedly connected to the top of the support. A protective cover for protecting the gear ring and gear is fixedly connected to the side wall of the discharge frame. The gear is rotatably connected to the inside of the protective cover. The gear and the gear ring mesh with each other. The output end of the adjusting motor passes through the inside of the protective cover and is fixedly connected to the rotating end of the gear. By setting the adjusting mechanism, the connection angle between the front and rear equipment can be adjusted, so that the gypsum powder can be smoothly transitioned, avoiding accumulation and clumping, reducing the risk of blockage, compensating for installation errors, adapting to complex environments, and improving flexibility and stability.

[0010] In the above technical solution, both of the fixed frames are fixed to the ground by expansion bolts. A rotary motor is fixedly connected to the rear side of one of the fixed frames. The output end of the rotary motor passes through the fixed frame and is fixedly connected to the rotating end of the rotating rod. By setting the rotary motor, the rotating rod and the discharge frame can be driven to rotate, thereby adjusting the discharge angle of the double or single hose screw conveyor.

[0011] In the above technical solution, further, the outer wall of the docking frame is provided with a limiting ring, and a visual monitoring camera for monitoring the blockage status inside the docking frame is fixedly connected through the top of the limiting ring. The docking frame is made of transparent plastic material. A pair of fixing rods are fixedly connected between the limiting ring and the side wall of the discharge frame. The limiting ring has four upper holes equidistantly opened on the side near the discharge frame. The outer wall of the main ring is fixedly connected with a lower ring, and the lower ring has four lower holes equidistantly opened on the side away from the discharge frame. A pair of limiting frames are fixedly connected at equal intervals to the outer wall of the docking frame. A limiting rod is slidably connected to the inner side of the limiting frame. An electric telescopic cylinder is fixedly connected to the side wall of the limiting frame. A connecting plate is fixedly connected to the output end of the electric telescopic cylinder. The connecting plate is fixedly connected to the outer wall of the limiting rod. The two limiting rods are inserted into two of the lower holes. A storage frame is fixedly connected to the side of the discharge frame away from the main ring. A circular hole is opened on the side wall of the storage frame. An upper fan-shaped perforated plate is fixedly connected to the inside of the circular hole. A lower fan-shaped perforated plate is provided on the side wall of the upper fan-shaped perforated plate. A positioning motor is fixedly connected to the outer wall of the storage frame. A central shaft is rotatably connected to the inside of the storage frame. The side end of the central shaft is fixedly connected to the side wall of the lower fan-shaped perforated plate. The output end of the positioning motor passes through the inside of the storage frame and is fixedly connected to the rotating end of the central shaft. A Y-shaped cavity is opened inside the discharge frame. A positioning ring is fixedly connected to the side of the discharge frame away from the storage frame. The two inclined branch ends of the Y-shaped cavity are connected to the inside of the storage frame. The Y-shaped cavity is equipped with a material vibrator. The bottom end of the side wall of the positioning ring is opened with an upper opening, which is connected to the horizontal branch end of the Y-shaped cavity. The side wall of the main ring is equally spaced with four lower openings, one of which is aligned with the upper opening. The positioning ring is rotatably and sealingly connected to the side wall of the main ring. Several stirring rods are fixedly connected at equal intervals to the outer wall of the central shaft. By configuring visual monitoring and bypass diversion structures at the junction, the blockage status of the connection point can be identified in real time. When material accumulates severely, the positioning motor drives the lower and upper fan-shaped perforated plates to align and connect. At the same time, the rotary motor drives the rotating rod to rotate, causing the discharge frame and storage frame to flip towards the feed hopper. This allows the gypsum powder conveyed by the flexible screw conveyor to be temporarily stored in the storage frame, avoiding continuous impact on the blockage point and causing equipment overload. After the blockage is relieved, the main road resumes conveying. The storage frame gradually replenishes the buffered material to the main road at a low rate through the rotation of the main ring, achieving gradual refilling. This design effectively prevents gypsum powder from compacting and caking at the junction, reduces damage to the flexible screw and hose caused by forced unblocking, and ensures the continuity and operational safety of long-distance conveying.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When conveying gypsum powder over long distances, the conveying distance of a single flexible screw conveyor is limited. By designing the discharge frame of the front machine and the feed hopper of the rear machine as a quick-assembly structure, multiple machines can be modularly connected in series. This structure can be quickly assembled and disassembled without complicated tools, which greatly shortens the downtime during equipment maintenance and material change, improves production continuity, and allows for flexible increase or decrease in the number of machines according to the actual conveying distance, adapting to the material supply needs of production lines of different sizes and reducing equipment configuration costs.

[0013] 2. By setting an adjustment mechanism, the connection angle of the two hose screw conveyors can be flexibly adjusted according to the layout of the workshop and the requirements of the conveying path. This ensures that the gypsum powder maintains a smooth flow at the transition point. This design effectively avoids the problems of material impact, dead corners of accumulation and wall clumping caused by improper angles in traditional fixed connections, reducing the risk of blockage. At the same time, the adjustable angle structure can compensate for equipment installation errors, adapt to complex spatial environments, and improve the layout flexibility and conveying stability of hose screw conveyors in autoclaved aerated concrete production lines.

[0014] 3. This invention, by setting up visual monitoring and bypass diversion structures at the assembly point, can determine the blockage status of the connection point in real time. When severe material accumulation is detected, the upper and lower fan-shaped perforated plates automatically connect, and the rotary motor drives the rotating rod to rotate, thereby allowing the gypsum powder in the flexible screw conveyor to be temporarily stored in the storage box, avoiding further impact on the blockage point and causing equipment overload. After the blockage is relieved, the main road resumes conveying, and the storage box gradually replenishes the buffered material to the main road at a low rate through the rotation of the main ring, realizing gradual refilling. This design effectively prevents the compaction and caking of sticky gypsum powder at the assembly point, reduces damage to the flexible screw and conveying hose caused by forced unblocking, and ensures the continuity of long-distance conveying and the safe operation of the equipment.

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0019] In actual use, it was found that the conveying length of a single device is limited. When the distance between the storage silo and the batching section is far, it is not possible to rely on a single device to complete the entire material supply. Multiple devices need to be spliced ​​and connected in series. Existing splicing mostly uses fixed flange connections, which are cumbersome to disassemble and assemble, time-consuming to connect, and difficult to guarantee the sealing and coaxiality of the connection. This leads to frequent powder leakage and material accumulation, which not only affects the conveying efficiency but also increases the difficulty of equipment maintenance and the risk of dust pollution. To solve the above problems, the following structure was invented.

[0020] like Figures 1-12The anti-clogging screw conveyor with online visual monitoring function shown includes a drive motor 1, a conveying hose 3, a feed hopper 4, a discharge frame 5, and a fixing frame 6. A pair of fixing frames 6 are provided, with a rotating rod 7 rotatably connected to the top of the two fixing frames 6. The discharge frame 5 is fixedly connected to the top of the rotating rod 7. The feed hopper 4 is fixedly connected to and communicates with the feed end of the conveying hose 3. A main ring 9 is provided on the side wall of the discharge frame 5, and a docking frame 10 is rotatably and sealingly connected to the side wall of the main ring 9. A pair of T-slots 11 are provided on the side wall of the docking frame 10. The outer wall of the feed hopper 4 is fixedly connected to... A pair of T-shaped blocks 12 are connected to the feed hopper 4. U-shaped frames 13 are fixedly connected to both sides of the outer wall of the docking frame 10. A pair of hinge seats 14 are fixedly connected to both sides of the outer wall of the docking frame 10. T-shaped screws 15 are rotatably connected to the inner side of the hinge seats 14. Locking rings 16 are threaded to the side end of the T-shaped screws 15. When docking, the T-shaped blocks 12 on the other feed hopper 4 are inserted into the T-shaped grooves 11. Then, the T-shaped screws 15 are flipped and inserted into the U-shaped frames 13. The locking rings 16 are tightened to make the discharge frame 5 and the feed hopper 4 tightly connected. An adjustment mechanism for adjusting the angle of the docking frame 10 is also provided. A flexible helical spring 2 is inserted inside the conveying hose 3. The drive motor 1 is fixedly connected to the rear side of the discharge frame 5. The discharge end of the conveying hose 3 is fixedly connected to the bottom end of the discharge frame 5. The discharge frame 5 is equipped with a transmission mechanism 8. The drive motor 1 is connected to the flexible helical spring 2 through the transmission mechanism 8 to drive the flexible helical spring 2 to rotate. The transmission mechanism 8 mainly consists of a drive sprocket, a driven sprocket, and a chain. The drive sprocket is installed at the output shaft end of the drive motor 1, and the driven sprocket is fixed to the drive end of the flexible helical spring 2. The chain surrounds the two sprockets to form a closed-loop transmission. When the drive motor 1 is running, the drive sprocket drives the driven sprocket to rotate through the chain engagement, thereby driving the flexible helical spring 2 to rotate synchronously inside the conveying hose 3. The spring blades form a relatively tight connection with the inner wall of the conveying hose 3. In the closed pushing space, the gypsum powder falling into the feed hopper 4 is continuously conveyed forward along the axial direction of the conveying hose 3 under the push of the rotating blades, and finally discharged from the discharge end. This pushing method relies on the friction and pushing force between the spiral surface of the flexible spiral spring 2 and the powder to achieve the closed, uniform and continuous feeding of materials. Moreover, the flexible spiral spring 2 is made of elastic metal wire wound into a spring-like structure without a central axis, which has good flexibility and elastic recovery ability. When the conveying hose 3 is bent or twisted due to the site layout, the flexible spiral spring 2 can deform synchronously with the conveying hose 3, and rely on its own elasticity to maintain the fit with the pipe wall for pushing. There is a movement gap between each coil of the flexible spiral spring 2, so there will be no rigid collision or jamming when rotating, thus adapting to any direction of the hose without interference.

[0021] Both mounting brackets 6 are fixed to the ground with expansion bolts. A rotary motor 23 is fixedly connected to the rear side of one of the mounting brackets 6. The output end of the rotary motor 23 passes through the mounting bracket 6 and is fixedly connected to the rotating end of the rotating rod 7.

[0022] When connecting two flexible screw conveyors for long-distance gypsum powder transport, first align the T-block 12 on the feed hopper 4 of the downstream equipment with the T-slot 11 of the feed hopper 4 of the upstream equipment, then flip the T-screw 15 to engage it in the U-shaped frame 13, and tighten the locking ring 16 to ensure the discharge frame 5 fits tightly with the feed hopper 4. This completes the connection and allows for quick assembly of the two flexible screw conveyors. During operation, the powder conveyed by the upstream flexible screw conveyor enters the feed hopper 4 of the downstream equipment through the discharge frame 5, main ring 9, and docking frame 10. Finally, the powder is transported over long distances via a flexible screw conveyor driven by the drive motor 1 of the downstream equipment. When disassembly is required after the equipment has been used, simply repeat the above steps in reverse.

[0023] In summary, through the above structural design, the conveying distance of a single flexible screw conveyor is limited when conveying gypsum powder over long distances. By designing the front machine discharge frame 5 and the rear machine feed hopper 4 as a quick-assembly structure, multiple devices can be modularly connected in series. This structure can be quickly assembled and disassembled without complicated tools, significantly reducing downtime during equipment maintenance and material replacement, improving production continuity. At the same time, the modular combination method can flexibly increase or decrease the number of devices according to the actual conveying distance, adapting to the material supply needs of production lines of different scales and reducing equipment configuration costs.

[0024] Based on the above embodiments, it was found during use that although the above can realize the rapid combination of multiple flexible screw conveyors to extend the overall conveying distance, it cannot flexibly adjust the connection angle of the front and rear equipment according to the on-site spatial layout. The fixed connection is not adaptable enough to deal with the avoidance of beams and columns in the workshop or the misalignment of equipment. Materials are prone to impact and accumulation at the transition point, forming dead corners, and there is still a risk of blockage. In order to solve the above problems, the above structure has been further improved.

[0025] The adjustment mechanism includes an adjustment motor 17, a gear 18, and a gear ring 19. A fixed ring 20 is fixedly connected to the outer wall of the discharge frame 5. The main ring 9 is rotatably and sealed to the outer wall of the fixed ring 20. The gear ring 19 is fixedly connected to the outer wall of the main ring 9. A support 21 is fixedly connected to the top of the rotating rod 7. The adjustment motor 17 is fixedly connected to the top of the support 21. A protective cover 22 for protecting the gear ring 19 and the gear 18 is fixedly connected to the side wall of the discharge frame 5. The gear 18 is rotatably connected to the inside of the protective cover 22. The gear 18 and the gear ring 19 mesh with each other. The output end of the adjustment motor 17 passes through the inside of the protective cover 22 and is fixedly connected to the rotating end of the gear 18.

[0026] A limiting ring 24 is provided on the outer wall of the docking frame 10. A visual monitoring camera 25 for monitoring the blockage status inside the docking frame 10 is fixedly connected through the top of the limiting ring 24. The docking frame 10 is made of transparent plastic. When the visual monitoring camera 25 is running, it captures images of the material flow at the joint in real time through the transparent plastic docking frame 10, monitors the material accumulation height, flow rate changes and wall agglomeration, identifies signs of blockage, and thus determines the blockage status of the joint in real time. A pair of fixing rods 26 are fixedly connected between the limiting ring 24 and the side wall of the discharge frame 5. The limiting ring 24 has four upper holes 27 equidistantly opened on the side closer to the discharge frame 5. A lower ring 28 is fixedly connected to the outer wall of the main ring 9. The lower ring 28 has four lower holes 29 equidistantly opened on the side away from the discharge frame 5.

[0027] A pair of limiting frames 30 are fixedly connected at equal intervals to the outer wall of the docking frame 10. Limiting rods 31 are slidably connected to the inner side of the limiting frame 30. An electric telescopic cylinder 32 is fixedly connected to the side wall of the limiting frame 30. A connecting plate 33 is fixedly connected to the output end of the electric telescopic cylinder 32. The connecting plate 33 is fixedly connected to the outer wall of the limiting rod 31. The two limiting rods 31 are inserted into the two lower holes 29.

[0028] During the docking process of two flexible screw conveyors, if the docking angle needs to be adjusted according to the on-site production scenario, the adjusting motor 17 can be started to drive the gear 18 to rotate, which in turn drives the meshing gear ring 19 to rotate, thereby driving the main ring 9 to rotate. During this process, since the limiting rod 31 is inserted into the lower hole 29, the docking frame 10 and the main ring 9 are in a locked connection state. Therefore, the rotation of the main ring 9 will drive the docking frame 10 to rotate together. After the 90-degree rotation adjustment is completed, the electric telescopic cylinder 32 can be started to drive the connecting plate 33 and the limiting rod 31 to move. At this time, the limiting rod 31 will be driven to gradually move out of the lower hole 29, and at the same time, the other end of the limiting rod 31 will gradually be inserted into the corresponding upper hole 27 until the limiting rod 31 is completely pulled out of the lower hole 29, thus completing the adjustment. Then, according to the adjusted angle, the T-shaped block 12 on the feed hopper 4 of the downstream equipment is inserted into the T-shaped groove 11 of the upstream equipment, and the above operation is repeated to lock and fix it. It should also be noted that the output of the regulating motor 17 is equipped with a rotary encoder, which precisely controls the rotation angle of the main ring 9 in 90-degree steps. The side wall of the limit frame 30 is equipped with a proximity switch, which monitors the position signals of the lower hole 29 on the outer wall of the main ring 9 and the upper hole 27 on the outer wall of the limit ring 24 in real time. When the hole position is aligned with the limit rod 31, the feedback is sent to the control system to ensure that the limit rod 31 is accurately stopped next to the corresponding lower hole 29 and upper hole 27.

[0029] In summary, the above structural design allows for flexible adjustment of the connection angle between the two hose screw conveyors according to the workshop layout and conveying path requirements. This ensures a smooth flow of gypsum powder at the transition point. This design effectively avoids material impact, dead corners, and wall clumping caused by improper angles in traditional fixed connections, reducing the risk of blockage. At the same time, the adjustable angle structure can compensate for equipment installation errors, adapt to complex spatial environments, and improve the layout flexibility and conveying stability of hose screw conveyors in autoclaved aerated concrete production lines.

[0030] Based on the above embodiments, it was found during use that although the angle adjustment mechanism can improve the smooth flow of materials at the joint, it is not effective in clearing subsequent materials when severe blockage occurs at the joint. When a large amount of gypsum powder accumulates at the joint, it is difficult to quickly alleviate the blockage by simply adjusting the angle. The continuous impact of subsequent materials on the blockage point can easily cause the flexible screw to overload and jam. Moreover, manual cleaning during shutdown takes a long time, which affects the continuous feeding stability of the autoclaved aerated concrete production line. To solve the above problems, further improvements were made to the above structure.

[0031] A storage frame 34 is fixedly connected to the side of the discharge frame 5 away from the main ring 9. A circular hole 35 is opened on the side wall of the storage frame 34. An upper fan-shaped perforated plate 36 is fixedly connected to the inside of the circular hole 35. A lower fan-shaped perforated plate 37 is provided on the side wall of the upper fan-shaped perforated plate 36. A positioning motor 38 is fixedly connected to the outer wall of the storage frame 34. A central shaft 39 is rotatably connected to the inside of the storage frame 34. The side end of the central shaft 39 is fixedly connected to the side wall of the lower fan-shaped perforated plate 37. The output end of the positioning motor 38 passes through the inside of the storage frame 34 and is fixedly connected to the rotating end of the central shaft 39. A Y-shaped cavity 40 is opened inside the discharge frame 5. A positioning ring 41 is fixedly connected to the side of the discharge frame 5 away from the storage frame 34.

[0032] The two inclined branch ends of the Y-shaped cavity 40 are connected to the interior of the storage frame 34. A material vibrator 44 is installed inside the Y-shaped cavity 40. The material vibrator 44 transmits excitation force to the cavity wall and the upper opening 42 area through high-frequency mechanical vibration, loosening and dislodging any attached or stuck gypsum powder. Its function is to prevent sticky gypsum powder from accumulating and clogging at the bend of the Y-shaped cavity 40 and around the upper opening 42, ensuring that the buffered material can be smoothly replenished to the main path through the upper opening 42 and lower opening 43, guaranteeing the stable operation of the gradual refilling process. An upper opening 42 is opened at the bottom of the side wall of the positioning ring 41, and the upper opening 42 is connected to the horizontal branch end of the Y-shaped cavity 40. Four lower openings 43 are equidistantly opened on the side wall of the main ring 9, one of which is a lower opening 43. The opening 43 is aligned with the upper opening 42. The positioning ring 41 is rotatably connected to the side wall of the main ring 9 through a sealing bearing. The positioning ring 41 is rotatably connected to the side wall of the main ring 9 through a sealing bearing. The two end faces are pressed with sealing gaskets, and O-rings are embedded in the gap to achieve rotational sealing and prevent powder leakage. Several stirring rods 45 are fixedly connected at equal intervals on the outer wall of the central shaft 39. Through the setting of the stirring rods 45, when the positioning motor 38 drives the central shaft 39 to rotate, the stirring rods 45 can drive the stirring rods 45 to continuously stir the gypsum powder in the storage frame 34. This effectively prevents the powder from caking and bridging due to static placement, keeps the material loose and uniform, and ensures that the gypsum powder in the storage frame 34 can fall smoothly to the lower opening 43, providing a stable and continuous material flow for the rotation and refeeding of the main ring 9, and avoiding local accumulation that could lead to interruption of refeeding or uneven feeding.

[0033] When the visual monitoring camera 25 detects a blockage at the connection point, it first controls the rotary motor 23 to start and drive the rotating rod 7 to rotate, thereby driving the discharge frame 5 to rotate and tilt the discharge frame 5 towards the storage frame 34. The material flows into the storage frame 34 under the action of gravity for temporary storage (at the same time, it drives the conveying hose 3 of the downstream equipment to move upward, increasing the tilt angle at the connection point, so that the gypsum powder can slide down faster by gravity, reducing the accumulation and retention of material at the connection point, thereby further alleviating the blockage). Then, the material will fall into the storage frame 34 under its own weight. At the same time, it controls the positioning motor 38 to start and drive the central shaft 39 to rotate, thereby driving the lower sector plate 37 to rotate, so that the lower sector plate 37 is aligned with the sector hole of the upper sector plate 36. Then, the material in the discharge frame 5 will fall into the storage frame 34 to avoid further impact on the blockage point and causing equipment overload. After the blockage is relieved, it controls the rotary motor 23 to drive the rotating rod 7 to reverse and reset, so that the material in the discharge frame 5 falls into the downstream feed hopper 4 for conveying away. During this process, the control positioning motor 38 starts the lower sector-shaped perforated plate 37 to rotate and reset, sealing the opening of the upper sector-shaped perforated plate 36 to prevent the simultaneous discharge of a large amount of material and further blockage of the downstream equipment. At the same time, the control regulating motor 17 starts to drive the gear 18 to rotate, which in turn drives the meshing gear ring 19 to rotate, thereby driving the main ring 9 to rotate (at this time, the limit rod 31 is inserted in the upper hole 27, so the docking frame 10 and the main ring 9 are separated). Thus, through the rotation of the main ring 9, the lower opening 43 and the upper opening 42 will be aligned, thereby discharging the material in the storage frame 34 through the Y-shaped cavity 40. At the same time, the control material vibrator 44 starts to vibrate and discharge a small amount of material in the storage frame 34, realizing gradual re-feeding.

[0034] In summary, by setting up a visual monitoring camera 25 and a bypass diversion structure at the assembly point, the blockage status of the connection point can be determined in real time. When severe material accumulation is detected, the upper fan-shaped perforated plate 36 and the lower fan-shaped perforated plate 37 automatically connect and control the rotary motor 23 to drive the rotating rod 7 to rotate, thereby guiding the gypsum powder in the flexible screw conveyor into the storage frame 34 for temporary storage, avoiding further impact on the blockage point and causing equipment overload. After the blockage is relieved, the main road resumes conveying, and the storage frame 34 gradually replenishes the buffered material to the main road at a low rate through the rotation of the main ring 9, realizing gradual refilling. This design effectively prevents the compaction and caking of sticky gypsum powder at the assembly point, reduces the damage to the flexible screw and conveying hose 3 caused by forced unblocking, and ensures the continuity of long-distance conveying and the safety of equipment operation. At the same time, when a single unit unloads material to a transport vehicle, the material can be temporarily stored in the storage frame 34 during the vehicle change interval, realizing vehicle change without stopping the machine and improving the efficiency of unloading operations.
