Belt feeder discharging chute anti-blocking device

Abstract

This invention relates to an anti-clogging device for a conveyor belt discharge chute. The invention includes a main body of the discharge chute, which is funnel-shaped, with a discharge pipe fixed to its bottom end. By providing an air outlet, during the conveyor belt's transport of material into the chute, the material falls onto rotating blades, causing them to rotate clockwise. The rotating blades, via a first connecting rope, pull a piston block downwards, compressing a first spring. The piston cylinder draws air from the air inlet pipe. During the rotation of a first rotating shaft, the shaft drives a rotating plate to rotate exactly 180 degrees, blocking the material and preventing it from falling onto the rotating blades. Under the action of the first spring, the piston block moves upwards, expelling gas from the piston cylinder through the air outlet pipe. This gas is then blown into the chute through the air outlet, creating a weak breeze that blows away any dust particles.

Description

Technical Field

[0001] This invention relates to the field of material chute technology, and in particular to an anti-clogging device for a conveyor belt material chute. Background Technology

[0002] A chute is a channel on the ground that transports goods from a high place to a low place. It has a smooth inner surface and allows the goods to slide down automatically. The chute is usually located below one end of a belt conveyor to receive the materials transported by the belt conveyor. Anti-blocking devices are installed in the chute to monitor the material blockage.

[0003] Existing anti-clogging devices are usually level gauges, which are typically installed near the bottom of the chute. The level gauge has a rotating vane. When the chute is discharging material normally, the vane rotates continuously inside the chute. When the chute is blocked by material, the material will accumulate inside the chute. The vane will stop rotating due to the obstruction of the accumulated material. The stopping of the level gauge will interlock with the belt conveyor, and the belt conveyor will stop running to prevent more material from clogging and accumulating in the chute.

[0004] However, current anti-clogging devices for chutes cannot suppress dust. As materials fall from the conveyor belt into the chute, they generate a large amount of dust, which disperses in all directions. This dust can harm the health of workers and may even cause danger. Therefore, we propose an anti-clogging device for conveyor belt discharge chutes to solve the above problems. Summary of the Invention

[0010] In one embodiment of the present invention, a second winding reel is fixedly connected to the surface of the first rotating shaft, a second connecting rope is fixedly connected to the surface of the second winding reel, a second guide wheel is fixedly connected to the inner wall of the housing, the second connecting rope passes around the second guide wheel, a rotating column is rotatably connected to the top of the housing via a bearing, a third winding reel is fixedly connected to the bottom end of the rotating column, one end of the second connecting rope is wound and fixedly connected to the surface of the third winding reel, a torsion spring is fixedly connected between the third winding reel and the top inner wall of the housing, and a rotating plate is fixedly connected to the top end of the rotating column.

[0013] In one embodiment of the present invention, a fixed plate is fixedly connected to the main body of the feeding chute, a second rotating shaft is rotatably connected to the fixed plate via a bearing, a roller is fixedly connected to the surface of the second rotating shaft, the roller is in close contact with the conveyor belt, a first transmission wheel is fixedly connected to the surface of the second rotating shaft, a third rotating shaft is rotatably connected to the fixed plate via a bearing, a second transmission wheel is fixedly connected to the surface of the third rotating shaft, the first transmission wheel and the second transmission wheel are connected by a transmission belt, a circular plate is fixedly connected to the surface of the third rotating shaft, a toggle plate is fixedly connected to the circular plate, a fifth spring is fixedly connected to the fixed plate, an impact ball is fixedly connected to one end of the fifth spring, and a impact plate is fixedly connected to the mounting plate.

[0014] In one embodiment of the present invention, two fixing rods are fixedly connected to the inner wall of the main body of the feeding chute, and a second baffle is fixedly connected to one end of the fixing rod, the second baffle being located directly above the rotating plate.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] This invention, by setting an air outlet, allows material to fall onto rotating blades during the conveyor belt's transport of material into the chute. The material causes the blades to rotate clockwise, which in turn drives a first winding reel via a first shaft. This reel winds a first connecting rope around itself, pulling a piston block downwards. The first spring is compressed, causing the piston cylinder to draw air in through the inlet pipe. During the rotation of the first shaft, a second connecting rope winds around it via a second winding reel, pulling out a second connecting rope from a third winding reel. This causes the second winding reel and rotating column to rotate, which in turn drives a rotating plate to rotate exactly 180 degrees. The rotating plate blocks the material, preventing it from falling onto the rotating blades. Under the action of the first spring, the piston block moves upwards, expelling gas from the piston cylinder through the outlet pipe. This gas is then blown into the chute through the air outlet, creating a weak breeze that blows away dust, thus solving the problem of current chute anti-clogging devices failing to suppress dust.

[0018] By installing a scraper, the bottom of the conveyor belt can be cleaned during operation, scraping off the material adhering to the conveyor belt to prevent it from falling outside the chute. The conveyor belt can drive the rollers to rotate, and the rollers drive the third shaft to rotate through the second shaft, the first transmission wheel and the transmission belt. The third shaft drives the circular plate and the actuating plate to rotate. The actuating plate will actuate the impact balls that pass by. Under the action of the fifth spring, the impact balls will hit the impact plate. The impact will generate rotation, and the vibration will cause the material adhering to the scraper to fall off.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Reference Figures 1-9 As shown, a conveyor belt chute anti-clogging device includes a chute body 1, which is funnel-shaped. A discharge pipe 2 is fixedly connected to the bottom end of the chute body 1. A spiral level gauge 3 is installed on the chute body 1, and a rotating vane 4 is installed on the spiral level gauge 3. A conveyor belt is located above the chute body 1 for conveying materials. The rotating vane 4 is located directly below one end of the conveyor belt. The material on the conveyor belt is conveyed into the chute body 1. The spiral level gauge 3 can drive the rotating vane 4 to rotate. The rotating vane 4 rotates continuously during normal operation. Due to inertia, most of the material will fall on the right side of the main body 1 of the chute, and thus will not fall directly on the left side of the main body 1 of the chute. This prevents most of the material from falling directly onto the rotating blade 4 and obstructing its normal rotation. The material will be discharged from the discharge pipe 2 at the bottom of the main body 1 of the chute. When the main body 1 of the chute is blocked, the material will accumulate at the bottom of the chute. When the material accumulates to a certain height, it will obstruct the rotation of the rotating blade 4. When the rotating blade 4 stops rotating, it will be interlocked with the conveyor belt, and the conveyor belt will stop running, thus preventing more material from accumulating in the main body 1 of the chute.

[0032] Furthermore, such as Figure 5As shown, the main body 1 of the discharge chute is provided with a first rotating shaft 5. A rotating block 6 is fixedly connected to the surface of the first rotating shaft 5. A rotating blade 7 is fixedly connected to the surface of the rotating block 6. A first winding wheel 8 is fixedly connected to the surface of the first rotating shaft 5. A first connecting rope 9 is wound and fixedly connected to the surface of the first winding wheel 8. A first guide wheel 10 is fixedly connected to the inner wall of the discharge chute main body 1. The first connecting rope 9 passes around the first guide wheel 10. A piston block 12 is fixedly connected to one end of the first connecting rope 9. A piston cylinder 11 is fixedly connected to the inner wall of the discharge chute main body 1 through a fixing block. The piston block 12 is slidably connected inside the piston cylinder 11. A first spring 13 is fixedly connected between the piston block 12 and the bottom inner wall of the piston cylinder 11. An air inlet pipe 14 is connected and fixedly connected to the top of the piston cylinder 11. The top of the plug cylinder 11 is connected to an air outlet pipe 15, and a connecting pipe 16 is fixed to the air outlet pipe 15. A horizontal pipe 17 is fixed to one end of the connecting pipe 16, and three inclined pipes 18 are fixed to the horizontal pipe 17. An air outlet 19 is connected to the inclined pipe 18 and is vertically downward. During the process of material entering the main body 1 of the feeding chute, a large amount of dust will be stirred up and dispersed in the air. During the process of material falling on the right side, it will drive the rotating blade 7 to rotate. The rotating blade 7 drives the rotating block 6 and the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the first winding wheel 8 to rotate. The first winding wheel 8 can wind the first connecting rope 9 onto it. The first connecting rope 9 can pull the piston block 12 to move downward. The first spring 13 is compressed, and the piston cylinder 11 can draw air from the outside through the air inlet pipe 14.

[0033] Furthermore, such as Figure 4 As shown, two supports 20 are fixed to the top inner wall of the piston cylinder 11. Each of the two supports 20 has an opening 21, which is located directly below the air inlet pipe 14 and the air outlet pipe 15, respectively. Two sealing plates 22 are rotatably connected to each of the two supports 20. One end of two adjacent sealing plates 22 is in contact with each other. Two sealing plates 22 are located below the openings 21, and the other two sealing plates 22 are located above the openings 21. A second spring 23 is fixed to each sealing plate 22 and the inner wall of the support 20. During the intake process of the piston cylinder 11, the two sealing plates 22 on the left open downwards, and air enters the piston cylinder 11. During the exhaust process of the piston cylinder 11, the two sealing plates 22 on the right open upwards, and air exits the piston cylinder 11.

[0034] Furthermore, such as Figure 3As shown, a housing 24 is fixedly connected to the inner wall of the main body 1 of the feeding chute. The top of the housing 24 is set as an inclined surface. The first rotating shaft 5 is rotatably connected to the housing 24 through a bearing. One of the rotating blades 7 extends out of the housing 24. A first baffle 25 is fixedly connected to the housing 24. The housing 24 can block most of the material from falling onto the rotating blade 7, so that the material only falls onto the rotating blade 7 on the right side. The first baffle 25 can prevent the material from falling onto the first winding reel 8.

[0035] Furthermore, such as Figure 5 and Figure 6 As shown, a second winding reel 26 is fixedly connected to the surface of the first rotating shaft 5, and a second connecting rope 27 is fixedly connected to the surface of the second winding reel 26. A second guide wheel 28 is fixedly connected to the inner wall of the housing 24, and the second connecting rope 27 passes around the second guide wheel 28. A rotating column 29 is rotatably connected to the top of the housing 24 via a bearing. A third winding reel 30 is fixedly connected to the bottom end of the rotating column 29. One end of the second connecting rope 27 is wound and fixedly connected to the surface of the third winding reel 30. A torsion spring 31 is fixedly connected between the third winding reel 30 and the top inner wall of the housing 24. A rotating plate 32 is fixedly connected to the top of the rotating column 29. During the rotation of the first rotating shaft 5, the first rotating shaft 5 drives the second winding reel 26 to rotate. The second winding reel 26 can wind the second connecting rope 27 onto it, and the second connecting rope 27 can pull out the second connecting rope 27 from the third winding reel 30. The second connecting rope 27 drives the third winding reel 30 to rotate. The spool 30 rotates, which in turn drives the rotating column 29 to rotate. The rotating column 29 then drives the rotating plate 32 to rotate. The torsion spring 31 accumulates energy, and the rotating plate 32 can rotate exactly 180 degrees. The rotating plate 32 will block the material falling towards the rotating blade 7. Under the action of the first spring 13, the piston block 12 moves upward, pushing the air in the piston cylinder 11 out of the air outlet pipe 15. The air is discharged from the air outlet 19 through the connecting pipe 16, the horizontal pipe 17, and the inclined pipe 18, forming a weak wind. The wind can blow the dust downward, effectively suppressing the dust dispersion. The upward movement of the piston block 12 can drive the first spool 8 and the first rotating shaft 5 to rotate through the first connecting rope 9. The rotating blade 7 of the first rotating shaft 5 rotates back. Under the action of the torsion spring 31, the rotating plate 32 will also return to its original position, and the material will continue to fall on the rotating blade 7, so that the wind can continuously blow into the main body 1 of the material chute, playing a role in dust suppression.

[0036] Furthermore, such as Figure 6As shown, a movable column 33 is slidably inserted into the top of the housing 24. The top of the movable column 33 is rounded, and a movable plate 34 is fixedly connected to the bottom of the movable column 33. A third spring 35 is fixedly connected between the movable plate 34 and the inner wall of the top of the housing 24. An impact column 36 is fixedly connected to the movable plate 34. The top of the impact column 36 contacts the inner wall of the top of the housing 24. During the rotation of the rotating plate 32, the rotating plate 32 can compress the movable column 33 to move. The movable column 33 drives the movable plate 34 and the impact column 36 to move, so that the impact column 36 does not contact the housing 24 and the third spring 35 is stretched. When the rotating plate 32 and the movable column 33 are not in contact, under the action of the third spring 35, the impact column 36 impacts the housing 24. The impact generates vibration, which can cause the material located at the top of the housing 24 to slide down.

[0037] Furthermore, such as Figure 8 As shown, a folded plate 37 is fixedly connected to the main body 1 of the feeding chute, and a guide post 38 is slidably inserted into the main body 1 of the feeding chute. A mounting plate 39 is fixedly connected to the top of the guide post 38, and a fourth spring 40 is fixedly connected between the mounting plate 39 and the folded plate 37. The fourth spring 40 is sleeved on the outside of the guide post 38. A scraper 41 is fixedly connected to the mounting plate 39. The scraper 41 contacts the bottom of the conveyor belt. A small amount of material will adhere to the conveyor belt. When the conveyor belt passes the scraper 41, the scraper 41 can scrape off the adhered material. The fourth spring 40 provides elasticity to the scraper 41.

[0038] Furthermore, such as Figure 8 As shown, a fixed plate 42 is fixedly connected to the main body 1 of the feeding chute. A second rotating shaft 43 is rotatably connected to the fixed plate 42 via bearings. A roller 44 is fixedly connected to the surface of the second rotating shaft 43, and the roller 44 is in close contact with the conveyor belt. A first transmission wheel 45 is fixedly connected to the surface of the second rotating shaft 43. A third rotating shaft 46 is rotatably connected to the fixed plate 42 via bearings. A second transmission wheel 47 is fixedly connected to the surface of the third rotating shaft 46. The first transmission wheel 45 and the second transmission wheel 47 are connected by a transmission belt 48. A circular plate 49 is fixedly connected to the surface of the third rotating shaft 46, and a toggle plate 50 is fixedly connected to the circular plate 49. The fixed plate 42... A fifth spring 51 is fixedly connected to the upper part of the mounting plate 39, and an impact ball 52 is fixedly connected to one end of the fifth spring 51. A receiving plate 53 is fixedly connected to the mounting plate 39. During the operation of the conveyor belt, the conveyor belt can drive the roller 44 to rotate, the roller 44 drives the second rotating shaft 43 to rotate, the second rotating shaft 43 drives the third rotating shaft 46 to rotate through the first transmission wheel 45, the transmission belt 48 and the second transmission wheel 47, the third rotating shaft 46 drives the circular plate 49 to rotate, the circular plate 49 drives the actuating plate 50 to rotate, and the actuating plate 50 will actuate the impact ball 52 to swing during the rotation of the actuating plate 50. The impact ball 52 can hit the receiving plate 53, and the impact generates vibration. The vibration can cause the material attached to the scraper 41 to fall off.

[0039] Furthermore, such as Figure 2 As shown, the inner wall of the material chute body 1 is fixed with two fixing rods 54. One end of the fixing rod 54 is fixed with a second baffle 55. The second baffle 55 is located directly above the rotating plate 4. The second baffle 55 can prevent some material from falling directly onto the rotating plate 4 and prevent the material from obstructing the normal rotation of the rotating plate 4.

[0040] Furthermore, such as Figure 9 As shown, the housing 24 has two circular holes. The first connecting rope 9 passes through the circular holes, and the moving column 33 slides through the circular holes. The bottom of the piston cylinder 11 has a circular hole, and the first connecting rope 9 passes through the circular hole. During the movement of the first connecting rope 9, the first connecting rope 9 slides in the circular hole. During the movement of the moving column 33, the moving column 33 slides in the circular hole.

[0041] Working principle: During operation, the material on the conveyor belt is fed into the main body 1 of the discharge chute. The spiral level gauge 3 drives the rotating blade 4 to rotate. During normal operation, the rotating blade 4 rotates continuously. Due to inertia, most of the material will fall on the right side of the discharge chute main body 1, preventing it from falling directly on the left side and obstructing its rotation. The material will be discharged from the discharge pipe 2 at the bottom of the discharge chute main body 1. When the discharge chute main body 1 becomes blocked, the material will accumulate at the bottom. When the material accumulates to a certain height, it will obstruct the rotation of the rotating blade 4. When the rotating blade 4 stops rotating, it will interlock with the conveyor belt, causing the conveyor belt to stop operating and preventing further material blockage. The material accumulates inside the main body 1 of the feeding chute. During the process of the material entering the main body 1 of the feeding chute, a large amount of dust is stirred up and dispersed into the air. As the material falls on the right side, it drives the rotating blade 7 to rotate. The rotating blade 7 drives the rotating block 6 and the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the first winding wheel 8 to rotate. The first winding wheel 8 can wind the first connecting rope 9 onto it. The first connecting rope 9 can pull the piston block 12 to move downward. The first spring 13 is compressed. The piston cylinder 11 can draw air from the outside through the air inlet pipe 14. During the rotation of the first rotating shaft 5, the first rotating shaft 5 drives the second winding wheel 26 to rotate. The second winding wheel 26 can wind the second connecting rope 27 onto it. The second connecting rope 27 can wind the second connecting rope 27 on the third winding wheel 30. Pulling out, the second connecting rope 27 drives the third winding reel 30 to rotate, the third winding reel 30 drives the rotating column 29 to rotate, the third rotating column 29 drives the rotating plate 32 to rotate, the torsion spring 31 accumulates energy, and the rotating plate 32 can rotate exactly 180 degrees. The rotating plate 32 will block the material falling towards the rotating blade 7. Under the action of the first spring 13, the piston block 12 moves upward, pushing the air in the piston cylinder 11 out of the air outlet pipe 15. The air is discharged from the air outlet 19 through the connecting pipe 16, the horizontal pipe 17 and the inclined pipe 18, forming a weak wind. The wind can blow the raised dust downward, effectively suppressing the dust dispersion. The upward movement of the piston block 12 can drive the first winding reel 8 and the first rotating shaft 5 to rotate through the first connecting rope 9. The rotating blade 7 of the first rotating shaft 5 As the rotating plate 32 rotates back, it resets under the action of the torsion spring 31, allowing the material to continue falling onto the rotating blade 7. This ensures a continuous flow of air into the main body of the chute 1, effectively suppressing dust. During the rotation of the rotating plate 32, it compresses the moving column 33, which in turn moves the moving plate 34 and the impact column 36. This prevents the impact column 36 from contacting the housing 24, causing the third spring 35 to be stretched. When the rotating plate 32 and the moving column 33 are not in contact, the impact column 36 impacts the housing 24 under the action of the third spring 35. This impact generates vibration, which causes the material at the top of the housing 24 to slide down. A small portion of the material adheres to the conveyor belt, which then scrapes off the adhered material as it passes the scraper 41.The fourth spring 40 provides elastic force to the scraper 41. During the operation of the conveyor belt, the conveyor belt can drive the roller 44 to rotate, the roller 44 drives the second rotating shaft 43 to rotate, the second rotating shaft 43 drives the third rotating shaft 46 to rotate through the first transmission wheel 45, the transmission belt 48 and the second transmission wheel 47, the third rotating shaft 46 drives the circular plate 49 to rotate, the circular plate 49 drives the actuating plate 50 to rotate, and the actuating plate 50 will actuate the impact ball 52 to swing during the rotation. The impact ball 52 can hit the impact plate 53, and the impact generates vibration, which can cause the material attached to the scraper 41 to fall off.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
