Description

Technical Field

[0001] This invention relates to the field of conveying equipment, and more particularly to a fly ash brick conveying device. Background Technology

[0002] Autoclaved fly ash bricks are made primarily from fly ash, lime, or cement, with the addition of appropriate amounts of gypsum and aggregates. The mixture is prepared, pressed into shape, and cured under high pressure, normal pressure, or naturally. Fly ash bricks are made primarily from fly ash and lime, with the addition of appropriate amounts of gypsum and aggregates, through a process of raw material preparation, pressing, and high-pressure steam curing.

[0003] Existing technology discloses some patent documents related to conveying equipment technology. Chinese invention application number CN201921704844.9 discloses a fly ash brick conveying device, including a base plate, a support frame fixedly connected to the bottom of the base plate, side plates fixedly connected to both sides of the top of the base plate, a motor fixedly connected to the front end of the outer side of the base plate, the output end of the motor passing through to the inner side of the side plate and fixedly connected to a drive wheel, a driven wheel being connected to the surface of the drive wheel via a conveyor belt, and a fixing plate fixedly connected to the top of the side plate.

[0004] In existing technologies, when conveying fly ash bricks, the conveyor line can perform horizontal, inclined, and vertical conveying. When fly ash bricks are conveyed from the bottom to a high place in a building via inclined conveyor, the conveyor belt is usually inclined to convey the fly ash bricks upward. When the conveying position is high, the conveying height is increased by increasing the inclination angle. When the inclination angle of the conveyor belt is large, some fly ash bricks on the conveyor belt are easy to slide down to the ground, which may injure the workers who are placing the fly ash bricks below, increasing the danger to the workers. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fly ash brick conveying device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a fly ash brick conveying device, comprising a base plate, two first mounting plates placed on the top of the base plate, two mounting blocks fixedly connected to the top of the base plate, one end of each of the two first mounting plates being rotatably connected to an adjacent mounting block, a first rotating shaft being rotatably connected to both ends of the two first mounting plates, a transmission roller being fixedly connected to the first rotating shaft, a conveyor belt being driven between the transmission rollers, and a conveying drive mechanism being connected to one of the first rotating shafts;

[0007] An angle adjustment mechanism is connected to the bottom of the first mounting plate. The angle adjustment mechanism is used to adjust the angle between the conveyor belt and the base plate, thereby adjusting the height of one end of the conveyor belt.

[0008] The surface of the conveyor belt is fixedly connected with multiple rubber baffles. Two second mounting plates are fixedly connected to opposite sides of the two first mounting plates. A second rotating shaft is rotatably connected between the two second mounting plates. A mating roller is fixedly connected to the second rotating shaft. A first motor is fixedly mounted on one side of one of the second mounting plates. The output shaft of the first motor is fixedly connected to one end of the second rotating shaft.

[0009] Multiple connecting plates are arranged in a circumferential array on the mating roller. An elastic clearance mechanism connects the mating roller and the connecting plates. As the mating roller rotates, each connecting plate corresponds one-to-one with a rubber stop strip. In operation, existing technologies for conveying fly ash bricks allow for horizontal, inclined, and vertical conveying. When fly ash bricks are conveyed from the bottom to a higher part of a building via inclined conveyor belts, the bricks are typically conveyed upwards by an inclined conveyor belt. When the conveying position is high, the conveying height is increased by increasing the inclination angle. When the angle is large, some fly ash bricks on the conveyor belt are prone to sliding down to the ground, potentially injuring workers placing them below and increasing the risk of injury. This technical solution addresses these problems. The specific working method is as follows: The angle between the conveyor belt and the base plate is adjusted by an angle adjustment mechanism, moving one end of the conveyor belt to the desired height. Then, the conveyor drive mechanism rotates the first rotating shaft below, driving the lower drive roller to rotate. The conveyor belt then moves between the two drive rollers. Simultaneously, the first motor is activated, causing its output shaft to drive the second rotating shaft, which in turn drives the mating roller. The second and first rotating shafts rotate in opposite directions. Workers below place the fly ash bricks to be conveyed on the conveyor belt, positioning them between two adjacent rubber baffles. The fly ash bricks move upwards with the conveyor belt, moving between two adjacent connecting plates on the mating roller. As these connecting plates rotate, the bricks pass between the mating roller and the conveyor belt, continuing upwards. When the fly ash bricks slide down the surface of the conveyor belt... When the fly ash bricks slide in the opposite direction to the rotation of the connecting plate, the surfaces of the fly ash bricks and the connecting plate come into contact, thus preventing the fly ash bricks from falling further and preventing them from falling directly to the ground and injuring the workers who placed them, ensuring the safety of the workers. Through the action of the elastic relief mechanism, when the surfaces of the fly ash bricks and the connecting plate collide, the connecting plate is elastically compressed and rotates, thereby reducing the rigid damage caused by the collision of the connecting plate and buffering the sliding of the fly ash bricks, making it easier for the fly ash bricks to be conveyed upwards again by friction and the resistance of the rubber baffle.

[0010] Preferably, the elastic clearance mechanism includes two fixed rings, which are respectively located at both ends of the mating roller. Insertion plates are fixedly connected to both ends of the connecting plate on the side closest to the mating roller. The insertion plates are slidably inserted into adjacent fixed rings. Multiple connecting blocks are fixedly connected to the fixed rings, each fixedly connected to an adjacent end of the mating roller. The number of connecting blocks corresponds one-to-one with the number of insertion plates. Multiple first springs are fixedly connected to the fixed rings, with both ends of the first springs fixedly connected to adjacent insertion plates and connecting blocks. During operation, the mating roller rotates via a second rotating shaft. The mating roller and the fixed rings are fixedly connected via multiple connecting blocks, allowing the mating roller to... The connecting roller drives the fixed ring to rotate. The connecting plate, which is slidably inserted into the fixed ring, rotates together with the fixed ring under the elastic action of the first spring. This allows the conveyed fly ash bricks to pass between the two rotating connecting plates. When the fly ash bricks slide down, the direction of their slide is opposite to the direction of rotation of the connecting plates, causing the surfaces of the fly ash bricks and the connecting plates to collide and come into contact. The connecting plates are squeezed and slide along the fixed ring, compressing the adjacent first spring and reducing the rigid damage caused by the collision of the connecting plates. This also buffers and stores energy for the sliding of the fly ash bricks. As the connecting plates continue to rotate, they push the fly ash bricks upward, making it easier for them to be conveyed upward again by friction and the resistance of the rubber baffles.

[0011] Preferably, the conveying drive mechanism includes a second motor and a first pulley. The second motor is fixedly mounted on the top of the base plate, and the first pulley is fixedly connected to one end of the first rotating shaft below. The second pulley is fixedly connected to the output shaft of the second motor, and a transmission belt is connected between the first pulley and the second pulley. During operation, the output shaft of the second motor drives the second pulley to rotate, and the transmission belt causes the first pulley to rotate synchronously, thereby causing the adjacent first rotating shaft to drive the transmission roller to rotate, so that the conveyor belt can transport fly ash bricks. The first rotating shaft is rotatably connected to the first mounting plate. When the angle adjustment mechanism changes the tilt angle of the first mounting plate, it will not affect the first rotating shaft and the first pulley.

[0012] Preferably, the angle adjustment mechanism includes a hydraulic rod and two U-shaped slide rails. The hydraulic rod is fixedly installed on the top of the base plate, and the two U-shaped slide rails are slidably connected to the bottom of the two first mounting plates. A first rotating ring is fixedly connected between the two U-shaped slide rails, and a second rotating ring is fixedly connected to the top of the piston shaft of the hydraulic rod. The first rotating ring and the second rotating ring are rotatably connected by a first connecting shaft. During operation, the piston shaft of the hydraulic rod moves upward, causing the second rotating ring to move upward. The second rotating ring then causes the first rotating ring to move upward, thereby causing the two U-shaped slide rails to move upward. This increases the angle between the conveyor belt and the base plate, and causes one end of the conveyor belt to move upward. When one end of the conveyor belt moves upward, the first rotating ring rotates around the first connecting shaft and the second rotating ring in accordance with the angle change of the first mounting plate. As the angle between the first mounting plate and the base plate increases, the U-shaped slide rails move along the first mounting plate towards the upper end, thereby increasing the conveying height.

[0013] Preferably, a mounting frame is fixedly connected between the tops of the two first mounting plates. A guide plate is placed between the top of the conveyor belt and the mounting frame. A second connecting shaft is fixedly connected to the top of the guide plate. The top end of the second connecting shaft passes through the mounting frame and extends above the mounting frame before being fixedly connected to a gear. A hydraulic cylinder is fixedly mounted on one side of the mounting frame. A rack is fixedly connected to the piston shaft of the hydraulic cylinder. The rack is slidably connected to the top of the mounting frame, and the rack and gear mesh. During operation, when the fly ash bricks pass through the mating rollers and continue to be conveyed upwards along the conveyor belt, one end of the fly ash brick contacts and is squeezed against the inclined surface of the guide plate, and passes through the gap between the guide plate and the first mounting plate, thereby discharging the fly ash bricks. The position of the fly ash bricks is calibrated by a guide, positioning them on one side of one of the first mounting plates. A hydraulic cylinder's piston shaft then moves a rack, which, through the meshing of the rack and gears, rotates a second connecting shaft. This tilts the guide plate in the opposite direction, calibrating the next fly ash brick and positioning it on the other side of the first mounting plate. The reciprocating movement of the hydraulic cylinder's piston shaft guides adjacent fly ash bricks to one side of each of the two first mounting plates, ensuring uniform force on the conveyor belt and improving transmission stability. Furthermore, calibrating the fly ash bricks increases the contact area between the brick's side and the rubber baffle, enhancing the resistance to the fly ash bricks and reducing the probability of them slipping downwards.

[0014] Preferably, a fixing plate is fixedly connected to each of the two opposing sides of the first mounting plates, and a contact plate is placed on each of the adjacent sides of the two fixing plates. Two limiting pins are fixedly connected to one side of each contact plate, and the limiting pins are slidably inserted into the adjacent fixing plates. A second spring is sleeved on each limiting pin, and the two ends of the second spring are fixedly connected to the adjacent fixing plates and the contact plates, respectively. During operation, when the fly ash brick approaches one side of the first mounting plate through the action of the guide plate, the side of the fly ash brick contacts the side of the contact plate. The contact and pressing action between the fly ash brick and the contact plate causes the contact plate to move the limiting pins. The limiting pins move along the sliding insertion point of the fixing plate, and the second spring is compressed under the pressing action of the fixing plate and the contact plate. The elastic buffer reduces the scraping and wear on the side of the first mounting plate caused by the pressing action between the fly ash brick and the side of the first mounting plate. Furthermore, the elastic clearance of the contact plate prevents the fly ash brick from having large contact friction on the side, which could cause difficulties in conveying the fly ash brick.

[0015] Preferably, each of the two contact plates has a placement groove on one adjacent side. A movable plate is hinged inside the placement groove. An arc-shaped pin is fixedly connected to the side of the movable plate near the placement groove. The arc-shaped pin is slidably inserted into the contact plate. The arc center of the arc-shaped pin and the hinge point of the movable plate are coaxially arranged. During operation, when the first mounting plate tilts upward, the movable plate is in an unfolded state due to gravity. The unfolding angle of the movable plate is limited by the arc-shaped pin. When the side of the fly ash brick contacts the movable plate, the movable plate will rotate into the placement groove. After the fly ash brick passes through, the movable plate reopens. When the fly ash brick located on the side slides down, one side of the fly ash brick is blocked by the unfolded end of the movable plate, further preventing the fly ash brick from sliding down and facilitating the smooth conveying of the fly ash brick.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The fly ash bricks move upwards at an incline along the conveyor belt. During this movement, they pass between two adjacent connecting plates on the mating roller. As the two adjacent connecting plates rotate, the fly ash bricks pass between the mating roller and the conveyor belt and continue moving upwards. When the fly ash bricks slide down the surface of the conveyor belt, the direction of the fall is opposite to the rotation direction of the connecting plates, causing the fly ash bricks to come into contact with the surfaces of the connecting plates. This prevents the fly ash bricks from falling directly to the ground and injuring the workers who placed them, thus ensuring the safety of the workers.

[0018] 2. When the fly ash bricks slide down, the direction of their slide is opposite to the direction of rotation of the connecting plate, causing the surfaces of the fly ash bricks and the connecting plate to collide and contact. The connecting plate is squeezed and slides along the fixed ring, compressing the adjacent first spring and reducing the rigid damage caused by the collision of the connecting plate. It also buffers and stores energy for the sliding of the fly ash bricks. As the connecting plate continues to rotate, it pushes the fly ash bricks upward, making it easier for the fly ash bricks to be conveyed upward again by friction and the resistance of the rubber baffle.

[0019] 3. The meshing action of the rack and pinion drives the second connecting shaft to rotate, thereby tilting the guide plate in another direction to guide and correct the position of the next fly ash brick, placing it on one side of another first mounting plate. The reciprocating movement of the piston shaft of the hydraulic cylinder causes the guide plate to guide two adjacent fly ash bricks to one side of the two first mounting plates respectively, keeping the force on the transmission belt uniform, improving the stability of transmission, and by guiding and correcting the position of the fly ash bricks, increasing the contact area between the side of the fly ash bricks and the rubber baffle, enhancing the obstruction of the fly ash bricks, and reducing the probability of the fly ash bricks sliding down.

[0020] 4. The contact and compression between the fly ash brick and the contact plate cause the contact plate to move the limiting pin. The limiting pin moves along the sliding joint of the fixed plate. Under the compression of the fixed plate and the contact plate, the second spring is compressed and deformed. The elastic buffer reduces the scraping and wear on the side of the first mounting plate caused by the compression between the fly ash brick and the side of the first mounting plate. Furthermore, the elastic clearance of the contact plate prevents the fly ash brick from having large side contact friction, which could cause difficulties in conveying the fly ash brick.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1 to 7 The fly ash brick conveying device shown includes a base plate 1, two first mounting plates 2 are placed on the top of the base plate 1, two mounting blocks 3 are fixedly connected to the top of the base plate 1, one end of each of the two first mounting plates 2 is rotatably connected to an adjacent mounting block 3, and a first rotating shaft 4 is rotatably connected to both ends between the two first mounting plates 2. A transmission roller 5 is fixedly connected to the first rotating shaft 4, and a conveyor belt 6 is driven between the transmission rollers 5. A conveying drive mechanism is connected to one of the first rotating shafts 4.

[0031] An angle adjustment mechanism is connected to the bottom of the first mounting plate 2. The angle adjustment mechanism is used to adjust the angle between the conveyor belt 6 and the base plate 1, thereby adjusting the height of one end of the conveyor belt 6.

[0032] Multiple rubber baffles 7 are fixedly connected to the surface of the conveyor belt 6. Two second mounting plates 8 are fixedly connected to the opposite sides of the two first mounting plates 2. A second rotating shaft 9 is rotatably connected between the two second mounting plates 8. A mating roller 10 is fixedly connected to the second rotating shaft 9. A first motor 11 is fixedly installed on one side of one of the second mounting plates 8. The output shaft of the first motor 11 is fixedly connected to one end of the second rotating shaft 9.

[0033] Multiple connecting plates 12 are arranged in a circumferential array on the mating roller 10. An elastic clearance mechanism connects the mating roller 10 and the connecting plates 12. As the mating roller 10 rotates, the connecting plates 12 correspond one-to-one with the rubber baffles 7. During operation, in existing technologies, when conveying fly ash bricks, the conveyor line can perform horizontal, inclined, and vertical conveying. When fly ash bricks are conveyed from the bottom to a higher part of the building via inclined conveying, the conveyor belt is usually inclined to transport the fly ash bricks upwards. When the conveying position is high, the inclination angle is increased to increase the conveying height. When the inclination angle of the conveyor belt is large, the transmission... Some fly ash bricks on the conveyor belt are prone to sliding down to the ground, potentially injuring workers placing them below and increasing the risk of injury. This technical solution addresses these problems. The specific working method is as follows: The angle between the conveyor belt 6 and the base plate 1 is adjusted using an angle adjustment mechanism, moving one end of the conveyor belt 6 to the desired conveying height. Then, the conveyor drive mechanism rotates the first rotating shaft 4 located below, driving the transmission rollers 5 below to rotate. Through transmission, the conveyor belt 6 is moved between the two transmission rollers 5. At this time, the first motor 11 is started, causing the first motor 11 to... The output shaft drives the second rotating shaft 9 to rotate, which in turn drives the mating roller 10 to rotate. The second rotating shaft 9 and the first rotating shaft 4 rotate in opposite directions. The worker below places the fly ash bricks to be conveyed onto the conveyor belt 6, positioning the fly ash bricks between two adjacent rubber baffles 7. The fly ash bricks move upwards with the inclined conveyor belt 6. During their movement on the conveyor belt 6, they pass between two adjacent connecting plates 12 on the mating roller 10, and as the two adjacent connecting plates 12 rotate, they pass between the mating roller 10 and the conveyor belt 6, continuing to move upwards. When the fly ash bricks slide down the surface of the conveyor belt 6... When the fly ash bricks slide in the opposite direction to the rotation of the connecting plate 12, the surfaces of the fly ash bricks and the connecting plate 12 come into contact, thus preventing the fly ash bricks from falling further and preventing them from falling directly to the ground and injuring the workers who placed them, thus ensuring the safety of the workers. Through the action of the elastic relief mechanism, when the surfaces of the fly ash bricks and the connecting plate 12 collide, the connecting plate 12 is elastically compressed and rotates, thereby reducing the rigid damage caused by the collision of the connecting plate 12 and buffering the sliding of the fly ash bricks, making it easier for the fly ash bricks to be conveyed upwards again by friction and the blocking action of the rubber baffle 7.

[0034] As a further embodiment of the present invention, the elastic clearance mechanism includes two fixed rings 13, which are respectively located at both ends of the mating roller 10. Connecting plates 14 are fixedly connected to both ends of the connecting plate 12 near the mating roller 10. The connecting plates 14 are slidably inserted into adjacent fixed rings 13. Multiple connecting blocks 15 are fixedly connected to the fixed rings 13, and each connecting block 15 is fixedly connected to an adjacent end of the mating roller 10. The number of connecting blocks 15 and connecting plates 14 corresponds one-to-one. Multiple first springs 16 are fixedly connected to the fixed rings 13, and the two ends of each first spring 16 are fixedly connected to adjacent connecting plates 14 and connecting blocks 15, respectively. During operation, the mating roller 10 is driven to rotate via the second rotating shaft 9. The mating roller 10 and the fixed rings 13 are fixedly connected via multiple connecting blocks 15, allowing the mating roller 10 to rotate. The fixed ring 13 rotates, and the insertion plate 14, which is slidably inserted into the fixed ring 13, rotates together with the fixed ring 13 under the elastic action of the first spring 16. The fly ash bricks are conveyed and pass between the two rotating connecting plates 12. When the fly ash bricks slide down, the direction of the fly ash bricks sliding down is opposite to the direction of rotation of the connecting plate 12, so that the surfaces of the fly ash bricks and the connecting plate 12 collide and contact. The connecting plate 12 is squeezed and slides along the fixed ring 13, and squeezes the adjacent first spring 16 to compress and deform the first spring 16, reducing the rigid damage caused by the collision of the connecting plate 12, and buffering and storing energy for the sliding of the fly ash bricks. As the connecting plate 12 continues to rotate, it pushes the fly ash bricks upward, so that the fly ash bricks can be conveyed upward again by friction and the blocking action of the rubber baffle 7.

[0035] As a further embodiment of the present invention, the conveying drive mechanism includes a second motor 17 and a first pulley 18. The second motor 17 is fixedly installed on the top of the base plate 1, and the first pulley 18 is fixedly connected to one end of the first rotating shaft 4 below. A second pulley 19 is fixedly connected to the output shaft of the second motor 17, and a transmission belt 20 is connected between the first pulley 18 and the second pulley 19. During operation, the output shaft of the second motor 17 drives the second pulley 19 to rotate, and the transmission belt 20 drives the first pulley 18 to rotate synchronously, thereby causing the adjacent first rotating shaft 4 to drive the transmission roller 5 to rotate, so that the conveyor belt 6 can transport fly ash bricks. The first rotating shaft 4 is rotatably connected to the first mounting plate 2. When the angle adjustment mechanism changes the tilt angle of the first mounting plate 2, it will not affect the first rotating shaft 4 and the first pulley 18.

[0036] As a further embodiment of the present invention, the angle adjustment mechanism includes a hydraulic rod 21 and two U-shaped slide rails 22. The hydraulic rod 21 is fixedly installed on the top of the base plate 1, and the two U-shaped slide rails 22 are slidably connected to the bottom of the two first mounting plates 2 respectively. A first rotating ring 23 is fixedly connected between the two U-shaped slide rails 22, and a second rotating ring 24 is fixedly connected to the top of the piston shaft of the hydraulic rod 21. The first rotating ring 23 and the second rotating ring 24 are rotatably connected through a first connecting shaft 25. During operation, the piston shaft of the hydraulic rod 21 moves upward, causing the second rotating ring 24 to move upward. The second rotating ring 24 drives the first rotating ring 23 to move upward, thereby driving the two U-shaped slide rails 22 to move upward, increasing the angle between the conveyor belt 6 and the base plate 1, and causing one end of the conveyor belt 6 to move upward. When one end of the conveyor belt 6 moves upward, the first rotating ring 23 rotates around the first connecting shaft 25 and the second rotating ring 24 in coordination with the angle change of the first mounting plate 2. As the angle between the first mounting plate 2 and the base plate 1 increases, the U-shaped slide rail 22 moves along the first mounting plate 2 towards the upper end, thereby increasing the conveying height.

[0037] As a further embodiment of the present invention, a mounting frame 26 is fixedly connected between the tops of the two first mounting plates 2. A guide plate 27 is placed between the top of the conveyor belt 6 and the mounting frame 26. A second connecting shaft 28 is fixedly connected to the top of the guide plate 27. The top end of the second connecting shaft 28 passes through the mounting frame 26 and extends above the mounting frame 26 before being fixedly connected to a gear 29. A hydraulic cylinder 30 is fixedly mounted on one side of the mounting frame 26. A rack 31 is fixedly connected to the piston shaft of the hydraulic cylinder 30. The rack 31 is slidably connected to the top of the mounting frame 26, and the rack 31 and the gear 29 mesh. During operation, when the fly ash brick passes through the mating roller 10 and continues to be conveyed upward along the conveyor belt 6, one end of the fly ash brick contacts and is pressed against the inclined surface of the guide plate 27, and passes through the gap between the guide plate 27 and the first mounting plate 2. This guide aligns the fly ash bricks, positioning them on one side of one of the first mounting plates 2. The piston shaft of the hydraulic cylinder 30 then moves the rack 31, and the meshing of the rack 31 and gear 29 rotates the second connecting shaft 28. This tilts the guide plate 27 in the opposite direction, guiding and aligning the next fly ash brick to the other side of the first mounting plate 2. The reciprocating movement of the piston shaft of the hydraulic cylinder 30 guides adjacent fly ash bricks to the sides of the two first mounting plates 2, ensuring uniform force on the conveyor belt and improving transmission stability. Furthermore, by guiding and aligning the fly ash bricks, the contact area between the sides of the fly ash bricks and the rubber baffle 7 is increased, enhancing the resistance to the fly ash bricks and reducing the probability of them sliding down.

[0038] As a further embodiment of the present invention, a fixing plate 32 is fixedly connected to each of the two opposing sides of the first mounting plates 2, and a contact plate 33 is placed on each adjacent side of the two fixing plates 32. Two limiting pins 34 are fixedly connected to one side of the contact plate 33, and the limiting pins 34 are slidably inserted into the adjacent fixing plates 32. A second spring 35 is sleeved on the limiting pin 34, and the two ends of the second spring 35 are fixedly connected to the adjacent fixing plate 32 and the contact plate 33, respectively. During operation, when the fly ash brick moves closer to one side of the first mounting plate 2 through the action of the guide plate 27, the fly ash brick... The side of the fly ash brick contacts the side of the contact plate 33, and the contact and compression between the fly ash brick and the contact plate 33 causes the contact plate 33 to drive the limiting pin 34 to move. The limiting pin 34 moves along the sliding insertion of the fixed plate 32, and the second spring 35 is compressed and deformed under the compression of the fixed plate 32 and the contact plate 33. The elastic buffer reduces the scraping and wear on the side of the first mounting plate 2 caused by the compression between the fly ash brick and the side of the first mounting plate 2. The elastic clearance of the contact plate 33 prevents the fly ash brick from having a large side contact friction, which would cause difficulties in conveying the fly ash brick.

[0039] As a further embodiment of the present invention, each of the two contact plates 33 has a placement groove 36 on one adjacent side. A movable plate 37 is hinged inside the placement groove 36. An arc-shaped pin 38 is fixedly connected to the side of the movable plate 37 near the placement groove 36. The arc-shaped pin 38 is slidably inserted into the contact plate 33. The arc center of the arc-shaped pin 38 and the hinge point of the movable plate 37 are coaxially arranged. During operation, when the first mounting plate 2 is tilted upward, the movable plate 37 is in an unfolded state under the action of gravity. The unfolding angle of the movable plate 37 is limited by the action of the arc-shaped pin 38. When the side of the fly ash brick comes into contact with the movable plate 37, the movable plate 37 will rotate into the placement groove 36. After the fly ash brick passes through, the movable plate 37 reopens. When the fly ash brick located on the side slides down, one side of the fly ash brick is blocked by the unfolded end of the movable plate 37, further preventing the fly ash brick from sliding down, which is conducive to the smooth conveying of the fly ash brick.

[0040] Working principle of this invention:

[0041] The angle between the conveyor belt 6 and the base plate 1 is adjusted by an angle adjustment mechanism, moving one end of the conveyor belt 6 to the required conveying height. Then, the conveyor drive mechanism rotates the first rotating shaft 4 located below, driving the transmission roller 5 below to rotate. Through transmission, the conveyor belt 6 is conveyed between the two transmission rollers 5. At this time, the first motor 11 is started, causing the output shaft of the first motor 11 to drive the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the mating roller 10 to rotate. The second rotating shaft 9 and the first rotating shaft 4 rotate in opposite directions. The worker below places the fly ash bricks to be conveyed on the conveyor belt 6, positioning the fly ash bricks between two adjacent rubber baffles 7. The fly ash bricks move upwards with the tilt of the conveyor belt 6. During the movement on the conveyor belt 6, the bricks move to the adjacent mating roller 10. Between the two connecting plates 12, and as the two adjacent connecting plates 12 rotate, they pass between the mating roller 10 and the conveyor belt 6 and continue to move upward. When the fly ash brick slides down from the surface of the conveyor belt 6, since the direction of the fly ash brick sliding is opposite to the direction of rotation of the connecting plate 12, the surface of the fly ash brick and the connecting plate 12 come into contact, thereby preventing the fly ash brick from continuing to fall and preventing the fly ash brick from directly sliding to the ground and injuring the workers who placed the fly ash brick, thus ensuring the safety of the workers. Through the action of the elastic relief mechanism, when the surface of the fly ash brick and the connecting plate 12 impacts and contacts, the connecting plate 12 is elastically squeezed and rotates, thereby reducing the rigid damage caused by the collision of the connecting plate 12 and buffering and storing the energy of the fly ash brick sliding, so that the fly ash brick can be conveyed upward again by friction and the blocking action of the rubber baffle 7.
