Description

Technical Field

[0001] This invention belongs to the technical field of buried scraper conveyors, specifically a buried scraper conveyor. Background Technology

[0002] Submerged scraper conveyors are transportation equipment that uses scraper chains moving within a closed casing to transport bulk materials to a predetermined destination. Submerged scraper conveyors have advantages such as small size, strong sealing, good rigidity, flexible process layout, convenient installation and maintenance, and the ability to feed and unload at multiple points, making them a widely used bulk material conveying equipment.

[0003] During horizontal conveying, the material is subjected to pressure from the scraper chain in the direction of movement and its own weight, generating internal friction between the materials. This friction ensures the stability of the material layer and is sufficient to overcome the external friction generated by the material moving in the trough, allowing the material to form a continuous flow and be conveyed. During vertical lifting, the material is subjected to pressure from the scraper chain in the direction of movement, generating lateral pressure in the material and forming internal friction. At the same time, due to the continuous feeding of the lower horizontal section, the lower material successively generates a pushing force on the upper material. This friction and pushing force are sufficient to overcome the external friction resistance generated by the material moving in the trough and the material's own weight, allowing the material to form a continuous flow and be lifted. The buried scraper conveyor can perform horizontal, inclined, and vertical conveying of materials.

[0004] When the material being conveyed by the scraper conveyor is sticky, it will stick to the scraper and chain, causing a large amount of material to accumulate on the surface of the scraper and chain. This requires timely cleaning by the staff and can easily cause the chain to jam or detach, as well as contaminate the material to be conveyed next time.

[0005] Therefore, the present invention provides a buried scraper conveyor. Summary of the Invention

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 4As shown in the embodiment of the present invention, a scraper conveyor includes a body 1; chains 2 are arranged on both sides of the interior of the body 1; a plurality of scrapers 3 are evenly arranged between the chains 2 on both sides; a cleaning unit is provided at the bottom of the discharge end of the body 1, and the cleaning unit cleans the chains 2 and scrapers 3; the cleaning unit includes a cleaning box 4; the cleaning box 4 is fixedly connected to the bottom of the discharge end of the body 1, and the top of the cleaning box 4 extends into the interior of the body 1; a pair of partitions 5 are fixedly connected to the bottom surface of the middle part of the cleaning box 4; the partitions 5 divide the cleaning box 4 into three cavities; openings are provided at the top of both ends of the cleaning box 4; a section of the bottom of the chain 2 and the bottom scraper 3 slide through the openings of the cleaning box 4; A rinsing assembly is installed inside the cavity in the middle of the cleaning box 4. This assembly is used to rinse the chain 2 and the scraper 3. During operation, the chain 2 drives the scraper 3 to move inside the machine body 1, pushing and conveying the material. After the chain 2 and scraper 3 have finished conveying the material, they move into the cleaning box 4. As the chain 2 and scraper 3 slowly and evenly pass through the middle cavity of the cleaning box 4, the rinsing assembly sprays multiple streams of water to rinse the surface of the scraper 3 and the chain 2, washing off any material adhering to them. This completes the cleaning of the scraper 3 and the chain 2, reducing the probability of the chain 2 getting stuck or detaching, and preventing the material being contaminated in the next shipment.

[0034] like Figures 3 to 5As shown, the rinsing assembly includes a housing 6; support legs are fixedly connected to the four corners of the bottom surface of the housing 6; the housing 6 is fixedly connected to the bottom surface of the cavity in the middle of the cleaning tank 4; a water pump 7 is fixedly connected inside the housing 6; a water inlet pipe 8 is fixedly connected to the water inlet end of the water pump 7; the water inlet pipe 8 penetrates the bottom surface of the housing 6, and the bottom end of the water inlet pipe 8 is fixedly connected to the bottom surface of the cavity in the middle of the cleaning tank 4; the cavity in the middle of the cleaning tank 4 is filled with clean water; hollow crossbars 10 are fixedly connected to both sides of the top surface of the housing 6; the two ends of the hollow crossbars 10 are respectively located below the chains 2 on both sides; a diverter 11 is fixedly connected to the outlet end of the water pump 7; the outlet end of the diverter 11 connects to the interior of the hollow crossbars 10; multiple [unclear] are installed on both sides of the top of the hollow crossbars 10. Nozzle 12; filter screen 9 is fixed between the supporting legs of the housing 6; the cavity side of the middle of the cleaning tank 4 is provided with a water inlet, an overflow outlet and a sludge removal outlet; the water inlet on the side of the cleaning tank 4 is connected to the clean water tank through a pipe; during operation, clean water in the clean water tank is introduced into the cavity in the middle of the cleaning tank 4, and the water pump 7 delivers the clean water to the hollow crossbars 10 on both sides through the water pump pipe 8, and then sprays it out by multiple nozzles 12 to form multiple upward spraying water curtains. When the scraper 3 and chain 2 move past, they are thoroughly rinsed. The wastewater after rinsing falls into the cavity in the middle of the cleaning tank 4, is filtered by the filter screen 9, and is then pumped out again by the water pump 7. Thus, not only can the scraper 3 and chain 2 be thoroughly cleaned, but water consumption is also saved.

[0035] like Figures 2 to 4 As shown, multiple impact baffles 13 are uniformly fixed inside the cavity near the middle of the machine body 1 in the cleaning box 4, and the impact baffles 13 are vertically arranged; multiple connecting components are uniformly bolted to the chains 2 on both sides; scrapers 3 are installed between the connecting components on both sides; the scrapers 3 can rotate through the connecting components; the bottom outer wall of the scraper 3 can collide and rotate with the impact baffles 13; a collection frame 14 is slidably installed at the bottom of the cavity near the middle of the machine body 1 in the cleaning box 4; during operation, when the chain 2 drives the scraper 3 into the interior of the cleaning box 4, the connecting components release the fixed scraper 3, and the scraper 3 hits the impact baffles 13, causing the scraper 3 and the chain 2 to vibrate and rotate, causing the material on the scraper 3 and the chain 2 to fall into the interior of the collection frame 14, thereby facilitating the recycling of materials by the staff and reducing material waste.

[0036] like Figures 7 to 9As shown, the connecting assembly includes a fixing plate 15; multiple fixing plates 15 are evenly bolted to the chains 2 on both sides; a connecting tube 16 is bolted to the top surface of the fixing plate 15; a rotating column 17 is rotatably mounted on the inner ring of the connecting tube 16 near the scraper 3; a return torsion spring 18 is sleeved on the outer ring of the middle part of the rotating column 17; a plate is fixedly connected to the end of the rotating column 17 near the scraper 3; a limiting structure is provided at the end of the connecting tube 16 away from the scraper 3, and the limiting structure can fix the rotating column 17; the limiting structure includes a sliding column 19; a sliding column 19 is slidably mounted on the inner ring of the end of the connecting tube 16 away from the scraper 3; the connecting tube 16 away from the scraper 3... Multiple limiting guide grooves 20 are evenly opened on the inner ring of one end of the sliding column 19; multiple limiting guide blocks 21 are evenly fixed to the outer ring of the sliding column 19; the limiting guide blocks 21 slide in cooperation with the limiting guide grooves 20; a sliding magnet 22 is fixedly connected to the end of the sliding column 19 away from the scraper 3; a square column 23 is bolted to the end of the sliding column 19 close to the scraper 3; a square groove 24 is opened on the end of the rotating column 17 away from the scraper 3; the square groove 24 matches the square column 23; release magnets 25 are fixedly connected to both sides of the cavity near the middle of the machine body 1 of the cleaning box 4; the release magnets 25 and the sliding magnets 22 attract each other; locking magnets 26 are fixedly connected to both sides of the cavity away from the middle of the machine body 1 of the cleaning box 4. The locking magnet 26 and the sliding magnet 22 repel each other. During operation, when the chain 2 drives the scraper 3 into the cleaning box 4, the connecting tubes 16 on both sides move between the release magnets 25 on both sides. The release magnets 25 attract the sliding magnet 22, causing the sliding magnet 22 to drive the sliding column 19 to slide out of the connecting tube 16, causing the limiting guide block 21 to slide along the limiting guide groove 20. The sliding column 19 drives the square column 23 to slide out of the square groove 24, releasing the rotating column 17, so that the scraper 3 can rotate and vibrate when it hits the impact baffle 13. When the chain 2 drives the scraper 3 out of the cleaning box 4, the scraper 3 is pushed by gravity and the return torsion spring 18. The scraper 3 is positioned vertically downwards, causing the rotating column 17 to reset and aligning the square groove 24 with the square column 23. When the connecting tubes 16 on both sides move between the locking magnets 26 on both sides, the locking magnets 26 generate a repulsive force on the sliding magnet 22. The sliding magnet 22 pushes the sliding column 19 into the interior of the connecting tube 16, pushing the square column 23 into the square groove 24, locking and fixing the rotating column 17. This keeps the scraper 3 in a vertical and fixed position, thus releasing the scraper 3 inside the cleaning box 4, which is beneficial for cleaning the scraper 3. At the same time, it keeps the scraper 3 locked outside the cleaning box 4, which is beneficial for conveying the scraper 3.

[0037] like Figures 7 to 8As shown, a pair of fixed clamping plates 27 are bolted to the plate of the rotating column 17; one end of a connecting rod 28 is bolted between the pair of fixed clamping plates 27; an mounting plate 29 is fixedly connected to the outer ring of the middle part of the connecting rod 28; multiple vertical grooves 30 are evenly opened in the middle part of the mounting plate 29; the mounting plate 29 is fixed to the top of the scraper 3 by multiple bolts, and the bolts pass through the vertical grooves 30; during operation, the position of the scraper 3 on the mounting plate 29 is controlled according to the different materials being conveyed and the changes in the conveying state, and the scraper 3 is locked and fixed to the mounting plate 29 by bolts passing through the vertical grooves 30, thereby adjusting the height of the scraper 3 when pushing the material, which facilitates the adjustment work of the operator and improves the applicability of the buried scraper conveyor.

[0038] like Figure 4 As shown, the top of the partition 5 is semi-circular rod-shaped, and the outer wall of the top of the partition 5 can slide in contact with the outer wall of the scraper 3; rubber scrapers are evenly arranged on the outer wall of the top of the partition 5; during operation, when the chain 2 drives the scraper 3 past the partition 5, the partition 5 blocks the scraper 3, causing the scraper 3 to rotate and slide against the top of the partition 5, so that the scraper 3 is in a horizontal state to enter and move out of the central cavity of the cleaning box 4, reducing the distance between the partition 5 and the top of the cleaning box 4, thereby reducing the probability of water droplets splashing out of the central cavity of the cleaning box 4.

[0039] like Figure 4 As shown, a side plate 31 is fixedly connected to the top of the partition 5 near the central cavity of the cleaning box 4; the side surface and bottom surface of the side plate 31 are evenly fixed to the inner wall of the cleaning box 4; an inner cavity 32 is formed between the side plate 31 and the partition 5; an air inlet slot is provided on the bottom surface of the inner cavity 32; a fan 33 is fixedly connected to the bottom surface of the inner cavity 32; the top of the side plate 31 is arc-shaped; multiple air outlet slots 34 are evenly provided on the top of the side plate 31; the air outlet slots 34 are inclined towards the central cavity of the cleaning box 4; the central cavity of the cleaning box 4... Air outlets are provided on both sides of the cavity. During operation, the nozzle 12 sprays water upward. When the water is impacted and water droplets splash, the fan 33 draws external air into the inner cavity 32 through the air inlet slot, forming an upward wind force. The generated wind is sprayed upward at an angle from the air outlet slot 34, blowing the splashed water droplets into the central cavity of the cleaning box 4, thereby preventing water droplets from splashing out of the central cavity of the cleaning box 4. This reduces the probability of water droplets causing the materials inside the machine body 1 to become damp. In addition, the generated wind accelerates the drying rate of the scraper 3 and the chain 2.

[0040] like Figure 4 and Figure 6As shown, a raised plate 35 is fixedly connected to the cavity of the cleaning box 4 away from the middle of the body 1, and the raised plate 35 is located between the locking magnet 26 and the partition plate 5; a plurality of raised teeth are uniformly fixedly connected to the top surface of the raised plate 35; a plurality of water passage holes 36 are uniformly opened on the peaks and valleys of the top surface of the raised plate 35; the top surface of the raised plate 35 slides in cooperation with the bottom of the scraper 3; during operation, when the chain 2 drives the scraper 3 to move to the top surface of the raised plate 35, the bottom of the scraper 3 slides in contact with the top surface of the raised plate 35, causing the scraper 3 to shake rapidly, shaking off the water droplets on the surface of the scraper 3 and the chain 2. The water droplets fall through the water passage holes 36, thereby improving the drying degree of the scraper 3 and the chain 2.

[0041] Working principle: When the chain 2 drives the scraper 3 into the cleaning box 4, the connecting pipes 16 on both sides move between the release magnets 25 on both sides. The release magnets 25 attract the sliding magnets 22. The sliding magnets 22 drive the sliding column 19 to slide out of the connecting pipe 16, and drive the limiting guide block 21 to slide along the limiting guide groove 20. The sliding column 19 drives the square column 23 to slide out of the square groove 24, releasing the rotating column 17. The scraper 3 hits the impact baffle 13, causing the scraper 3 and the chain 2 to vibrate and rotate, causing the material on the scraper 3 and the chain 2 to fall into the collection box 14.

[0042] When the chain 2 drives the scraper 3 past the partition 5, the partition 5 blocks the scraper 3, causing the scraper 3 to rotate and slide against the top of the partition 5, so that the scraper 3 is in a horizontal state and enters the middle cavity of the cleaning box 4. Then, under the push of gravity and the return torsion spring 18, the scraper 3 is in a vertical downward state.

[0043] Clean water from the clean water tank is introduced into the cavity in the middle of the cleaning tank 4. The water pump 7 delivers the clean water to the hollow crossbars 10 on both sides through the water pipe 8, and then sprays it out from multiple nozzles 12, forming multiple upward spraying water curtains. When the scraper 3 and chain 2 move past, they are thoroughly washed. The wastewater after washing falls into the cavity in the middle of the cleaning tank 4 and is filtered by the filter screen 9. The water flow washes the surface of the scraper 3 and chain 2, thereby completing the cleaning work of the scraper 3 and chain 2, reducing the probability of chain 2 getting stuck or detached, and avoiding the probability of the next conveyed material being contaminated. At the same time, the nozzles 12 spray water upward. When the water flow is impacted and water droplets splash, the fan 33 draws external air into the inner cavity 32 through the air inlet slot, forming an upward wind force. The generated wind is sprayed upward at an angle from the air outlet slot 34, blowing the splashed water droplets into the cavity in the middle of the cleaning tank 4, preventing the water droplets from splashing out of the cavity in the middle of the cleaning tank 4.

[0044] Afterwards, when the chain 2 drives the scraper 3 to move to the top surface of the convex plate 35, the bottom of the scraper 3 slides into contact with the top surface of the convex plate 35, causing the scraper 3 to shake rapidly, shaking off the water droplets on the surface of the scraper 3 and the chain 2, and the water droplets fall through the water passage 36.

[0045] Finally, when the chain 2 drives the scraper 3 to move out of the cleaning box 4, the scraper 3 is pushed by gravity and the return torsion spring 18 to be in a vertical downward state, which drives the rotating column 17 to reset, so that the square groove 24 is aligned with the square column 23. When the connecting tubes 16 on both sides move between the locking magnets 26 on both sides, the locking magnets 26 generate a repulsive force on the sliding magnets 22. The sliding magnets 22 push the sliding column 19 into the interior of the connecting tube 16, push the square column 23 into the square groove 24, lock and fix the rotating column 17, so that the scraper 3 is kept in a vertical state and locked.
