Description

Technical Field

[0001] The invention relates to the technical field of building material production machinery and equipment, and in particular to a high-efficiency automatic brick unloading machine. Background Art

[0002] Refractory insulation materials are widely used in steel, ceramics, cement, glass, refractory materials, aviation and other industries for fire resistance and insulation. Refractory insulation bricks are mostly made by high-temperature sintering in tunnel kilns. Existing refractory bricks are stacked on kiln cars in a criss-cross manner. In order to increase production, the gap between bricks in the fire channel is small, making it difficult to unload bricks automatically. Therefore, manual unloading is currently widely used. However, this method is not only labor-intensive and inefficient, but also has high manufacturing costs. Therefore, refractory material manufacturers are in urgent need of an automatic and efficient brick unloading machine to solve these problems. Summary of the invention

[0003] The purpose of the present invention is to provide a high-efficiency automatic brick unloading machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The present invention provides a high-efficiency automatic brick unloading machine, which comprises:

[0006] A frame, which can move longitudinally relative to the kiln car;

[0007] A lifting frame, which is connected to the frame and can move vertically relative to the frame;

[0008] A lifting mechanism connected to the lifting frame to drive the lifting frame to move vertically;

[0009] a first conveying mechanism;

[0010] a second conveying mechanism;

[0011] A first brick pushing mechanism, which is connected to the lifting frame, and can move laterally relative to the lifting frame, and is connected to the first conveying mechanism to push bricks to the first conveying mechanism;

[0012] A driving mechanism connected to the lifting frame, wherein the driving mechanism is connected to the first brick pushing mechanism to drive the first brick pushing mechanism to move in a lateral direction;

[0013] A second brick pushing mechanism, which is connected to the lifting frame, and the second brick pushing mechanism is connected to the second conveying mechanism to push bricks to the second conveying mechanism;

[0014] The brick turning mechanism is respectively arranged on the first brick pushing mechanism and the second brick pushing mechanism to drive each row of bricks on the kiln car to turn over to the first brick pushing mechanism and the second brick pushing mechanism accordingly.

[0015] The present invention has at least the following beneficial effects: the entire brick layer arranged horizontally on the kiln car is unloaded by adopting the first brick pushing mechanism, the driving mechanism, the first conveying mechanism and the brick turning mechanism located on the first brick pushing mechanism, and the driving mechanism can move the first brick pushing mechanism and the brick turning mechanism closer to the bricks; the brick turning mechanism turns the first row of bricks over to the first brick pushing mechanism, so that the first brick pushing mechanism pushes the row of bricks one by one to the first conveying mechanism, so that the first conveying mechanism can safely and quickly convey the dumped bricks one by one; the first brick pushing mechanism and the brick turning mechanism can move laterally under the action of the driving mechanism to approach the bricks, thereby unloading each subsequent row of bricks of the entire brick layer.

[0016] In addition, the entire brick layer arranged longitudinally on the kiln car is unloaded through the second brick pushing mechanism, the second conveying mechanism, the frame and the brick turning mechanism located on the second brick pushing mechanism. Since the frame can move longitudinally relative to the kiln car, it can drive the second brick pushing mechanism and the brick turning mechanism to approach the brick layer, and use the brick turning mechanism to turn the first row of bricks over to the second brick pushing mechanism, so that the second brick pushing mechanism pushes the row of bricks to the second conveying mechanism one by one, so that the second conveying mechanism can safely and quickly convey the dumped bricks one by one; the second brick pushing mechanism and the brick turning mechanism can move longitudinally to approach the bricks when the frame moves relative to the kiln car, thereby unloading each subsequent row of bricks of the entire brick layer.

[0017] The first brick pushing mechanism, the second brick pushing mechanism and the brick turning mechanism are arranged on the lifting frame, and the lifting mechanism is used to drive the lifting frame to move in the up and down directions, so as to realize the unloading of each layer of bricks vertically stacked on the kiln car.

[0018] The efficient automatic brick unloader can automatically unload the staggered brick piles on the kiln car, ensuring that the bricks can be safely unloaded and transported out one by one, without the need for manual unloading, greatly improving the efficiency of brick unloading.

[0019] As a further improvement of the above technical solution, the first conveying mechanism is connected to the lifting frame, and the conveying direction of the first conveying mechanism is set in the horizontal direction; the second conveying mechanism is connected to the lifting frame, and the conveying direction of the second conveying mechanism is set in the longitudinal direction, and the second conveying mechanism is connected to the first conveying mechanism. The first conveying mechanism and the second conveying mechanism are arranged on the lifting frame, and can move up and down with the lifting frame; and the first conveying mechanism and the second conveying mechanism are vertically connected, so that the bricks unloaded by the first brick pushing mechanism and the second brick pushing mechanism can be uniformly transported out from the outlet end of the first conveying mechanism or the second conveying mechanism, without setting up multiple conveying mechanisms to connect the first conveying mechanism and the second conveying mechanism respectively, which greatly reduces the enterprise cost.

[0020] As a further improvement of the above technical solution, the bottom of the frame is provided with a guide wheel and a first motor for driving the guide wheel to rotate; the high-efficiency automatic brick unloading machine also includes a guide rail; the guide rail is fixedly arranged along the longitudinal direction, and the guide wheel is connected to the guide rail and can move along the guide rail. The guide wheel and the first motor are arranged at the bottom of the frame, and the frame can be automatically moved along the longitudinal direction by the drive of the first motor, without the need to manually move the frame or drive the kiln car to move, and the operation is very simple.

[0021] As a further improvement of the above technical solution, the efficient automatic brick unloading machine also includes:

[0022] The third conveying mechanism has running wheels at the bottom;

[0023] A fourth conveying mechanism, one end of which is connected to the lifting frame, and the other end of which is connected to the third conveying mechanism; the second conveying mechanism, the fourth conveying mechanism and the third conveying mechanism are connected in sequence and have the same conveying direction.

[0024] The fourth conveying mechanism and the third conveying mechanism are sequentially arranged at the outlet end of the second conveying mechanism, so that the unloaded bricks are moved to the third conveying mechanism through the fourth conveying mechanism, which is convenient for the staff to take away the bricks or transfer the bricks by transfer. The bottom of the third conveying mechanism is provided with running wheels, so that when the frame moves longitudinally or the lifting frame moves vertically, the longitudinal position of the third conveying mechanism can be adjusted by the running wheels, so that the third conveying mechanism, the fourth conveying mechanism and the lifting frame can still maintain a stable connection, thereby ensuring that the brick unloading work can proceed normally.

[0025] Moreover, the conveying directions of the second conveying mechanism, the fourth conveying mechanism and the third conveying mechanism are consistent and are all arranged longitudinally, which not only makes it convenient for the staff to transfer bricks on one side, but also improves the efficiency of brick conveying.

[0026] As a further improvement of the above technical solution, the first conveying mechanism, the second conveying mechanism, the third conveying mechanism and the fourth conveying mechanism are belt conveyors. The belt conveyors can convey bricks quickly and safely at a low cost.

[0027] As a further improvement of the above technical solution, the brick turning mechanism includes:

[0028] A mounting seat, which is fixedly arranged;

[0029] A rotating shaft connected to the mounting seat, the rotating shaft being rotatable around its horizontal axis;

[0030] A brick turning rod, one end of which is connected to the rotating shaft, and the brick turning rods are arranged at intervals along the axial direction of the rotating shaft;

[0031] A second motor is connected to the mounting seat, and the second motor is drivingly connected to the rotating shaft.

[0032] A brick-turning rod is arranged on the rotating shaft. When the second motor drives the rotating shaft to rotate, the brick-turning rod can rotate with the rotating shaft, thereby exerting force on the top surface of the brick, causing the brick to turn over onto the first brick-pushing mechanism or the second brick-pushing mechanism; the brick-turning rod is arranged at intervals along the axial direction of the rotating shaft, and can turn over a row of bricks, causing a whole row of bricks to dump onto the first brick-pushing mechanism or the second brick-pushing mechanism, thereby speeding up the brick unloading speed.

[0033] As a further improvement of the above technical solution, the brick turning rod is a rubber strip. Using the rubber strip as the brick turning rod can ensure that the bricks are turned over when the rubber strip exerts a force, while preventing the surface appearance of the bricks from being damaged, thereby reducing the scrap rate of the bricks.

[0034] As a further improvement of the above technical solution, the first brick pushing mechanism and the second brick pushing mechanism have the same structure, and both include:

[0035] A support base, which is provided with a brick support plate; the mounting base is connected to the support base;

[0036] A push plate is arranged on the brick support plate, and the push plate can move horizontally along the length direction of the brick support plate; the brick turning rod is located above the push plate;

[0037] A driving device is installed on the supporting seat, and the driving device is connected with the pushing plate to drive the pushing plate to move horizontally.

[0038] A brick support plate is arranged on the support seat, which can effectively receive a whole row of bricks overturned by the brick turning mechanism, and utilizes a push plate, under the operation of the driving device, to smoothly push a whole row of bricks to the first conveying mechanism or the second conveying mechanism, so that the bricks can be conveyed out one by one.

[0039] As a further improvement of the above technical solution, the driving mechanism includes:

[0040] A connecting guide rail, which is horizontally arranged and connected to the lifting frame;

[0041] A slider, which is connected to the connecting guide rail and can move laterally along the connecting guide rail;

[0042] A chain, both ends of which are respectively connected to the lifting frame;

[0043] A movable seat connected to the slider, wherein the first brick pushing mechanism is connected to the bottom of the movable seat; the movable seat is provided with a sprocket set, and the sprocket set is meshedly connected with the chain;

[0044] The third motor is installed on the moving seat, and the third motor is drivingly connected with the sprocket set to drive the moving seat to move laterally along the chain.

[0045] A connecting rail is arranged on the lifting frame, and the sliding connection between the slider and the connecting rail enables the moving seat to move smoothly laterally with the first brick pushing mechanism. Through the meshing connection between the chain and the sprocket group on the moving seat, when the third motor drives the sprocket group to operate, the moving seat can move laterally along the fixed chain. By adopting this chain transmission mode, the driving mechanism drives the heavier first brick pushing mechanism and the brick turning mechanism to move laterally together.

[0046] As a further improvement of the above technical solution, the lifting mechanism includes:

[0047] A driving sprocket connected to the frame, the driving sprocket being rotatable along its horizontal axis;

[0048] A first driven sprocket is connected to the frame, the first driven sprocket is located above the lifting frame, and the axial direction of the first driven sprocket is consistent with that of the driving sprocket;

[0049] A second driven sprocket is connected to the frame, the second driven sprocket is located above the lifting frame, and the axial direction of the second driven sprocket is consistent with that of the driving sprocket;

[0050] A third driven sprocket is connected to the frame, the third driven sprocket is located between the first driven sprocket and the second driven sprocket, and the axial direction of the third driven sprocket is consistent with that of the driving sprocket;

[0051] A counterweight block, which is arranged below the driving sprocket;

[0052] A main chain meshingly connected with the driving sprocket, one end of the main chain being connected with the counterweight;

[0053] a first secondary chain meshingly connected with the first driven sprocket, one end of the first secondary chain being connected with the main chain, and the other end of the first secondary chain being connected with one side of the lifting frame;

[0054] a second secondary chain meshingly connected with the second driven sprocket and the third driven sprocket, one end of the second secondary chain being connected with the main chain, and the other end being connected with the opposite side of the lifting frame;

[0055] A fourth motor is connected to the frame, and the fourth motor is drivingly connected to the driving sprocket.

[0056] A counterweight is arranged at one end of the main chain to reduce the load on the fourth motor and save energy. A first sub-chain and a second sub-chain are arranged at the other end of the main chain. The first sub-chain can be connected to one side of the lifting frame after being connected via the first driven sprocket, and the second sub-chain can be connected to the other side of the lifting frame after being connected via the third driven sprocket and the second driven sprocket, so that the main chain can pull the first sub-chain and the second sub-chain at the same time, thereby applying a pulling force to the lifting frame so that the lifting frame can be stably lifted and lowered without shaking. The setting of the third driven sprocket can change the pulling direction of the second sub-chain on the main chain, thereby ensuring that the first sub-chain and the second sub-chain can drive the lifting frame to rise or fall horizontally as a whole.

[0082] Reference Figures 1 to 9 , several embodiments of the high-efficiency automatic brick unloading machine of the present invention are given below.

[0083] In an existing brick production workshop, a kiln car 800 carries staggered and stacked bricks 810. Traveling wheels and a motor for controlling the rotation of the traveling wheels are installed at the bottom of the kiln car 800. A second guide rail 820 is correspondingly installed on the ground. The kiln car 800 can be adjusted in position relative to the frame 100 by the traveling wheels walking on the second guide rail 820. A locking mechanism can be set on the kiln car 800 to drive the kiln car to be temporarily locked on the second guide rail 820, so as to facilitate the efficient automatic brick unloading machine to unload bricks.

[0084] like Figures 1 to 8As shown, an embodiment of the present invention provides a high-efficiency automatic brick unloading machine, which includes: a frame 100, a lifting frame 300, a lifting mechanism 200, a first conveying mechanism 530, a second conveying mechanism 630, a first brick pushing mechanism 520, a driving mechanism 400, a second brick pushing mechanism 620 and a flipping mechanism.

[0085] The frame 100 may be formed by connecting a plurality of metal profiles. The frame 100 may move longitudinally relative to the kiln car 800, and the kiln car 800 may be controlled to move longitudinally, or the frame 100 may be controlled to move longitudinally (ie, in the Y direction).

[0086] Specifically, four guide wheels 110 and a first motor 140 for driving the guide wheels 110 to rotate are installed at the bottom of the frame 100. A relative set of guide wheels 110 are connected through a transmission shaft. The first motor 140 drives the gears on the transmission shaft through the gears on its output shaft, thereby causing the guide wheels 110 to rotate.

[0087] The efficient automatic brick unloading machine further includes a guide rail 130 disposed on the ground. The guide rail 130 is fixedly disposed in the longitudinal direction, and the guide wheel 110 is connected to the guide rail 130 and can move longitudinally along the guide rail 130 to adjust the longitudinal position of the frame 100 relative to the kiln car 800. The first motor 140 can be a stepping motor to accurately control the moving distance of the frame 100 on the guide rail 130.

[0088] The lifting frame 300 can be formed by connecting a plurality of metal profiles. The lifting frame 300 is connected to the frame 100 and can move vertically relative to the frame 100. Specifically, U-shaped pulleys can be installed on both sides of the lifting frame 300, and the frame 100 is correspondingly provided with a first guide rail 120. The U-shaped pulley is connected to the first guide rail 120, so that the lifting frame 300 is more stable and does not shake when being lifted.

[0089] The lifting mechanism 200 is connected to the lifting frame 300 to drive the lifting frame 300 to move vertically. Figure 5 As shown, specifically, the lifting mechanism 200 includes: a driving sprocket 211, a first driven sprocket 242, a second driven sprocket 243, a third driven sprocket 241, a counterweight 220, a main chain 230, a first secondary chain 231, a second secondary chain 232 and a fourth motor 210.

[0090] The frame 100 is provided with a plurality of transmission shafts through a bearing seat, and the driving sprocket 211 is connected to the frame 100 by being installed on one of the transmission shafts, and the driving sprocket 211 can rotate along its horizontal axis.

[0091] The first driven sprocket 242 is connected to the frame 100 by being installed on one of the transmission shafts. The first driven sprocket 242 is located above the lifting frame 300 , and the axial direction of the first driven sprocket 242 is consistent with that of the driving sprocket 211 .

[0092] The second driven sprocket 243 is connected to the frame 100 by being installed on one of the transmission shafts. The second driven sprocket 243 is located above the lifting frame 300 , and the axial direction of the second driven sprocket 243 is consistent with that of the driving sprocket 211 .

[0093] The third driven sprocket 241 is connected to the frame 100 by being installed on one of the transmission shafts. The third driven sprocket 241 is located between the first driven sprocket 242 and the second driven sprocket 243 . The axial direction of the third driven sprocket 241 is consistent with that of the driving sprocket 211 .

[0094] In this embodiment, two of each of the driving sprocket 211 , the first driven sprocket 242 , the second driven sprocket 243 and the third driven sprocket 241 are provided.

[0095] The counterweight 220 is disposed below the driving sprocket 211. The counterweight 220 may be provided with a pulley 221, and the frame 100 is provided with a guide rail or a slide slot correspondingly, and the pulley 221 is connected with the guide rail or the slide slot, so that the counterweight is more stable during the lifting process.

[0096] The main chain 230 is meshedly connected with the driving sprocket 211 , and one end of the main chain 230 can be connected with the counterweight 220 by welding, so that the main chain 230 can pull up the counterweight 220 .

[0097] The first secondary chain 231 is meshedly connected with the first driven sprocket 242 , one end of the first secondary chain 231 is connected to the main chain 230 , and the other end of the first secondary chain 231 is connected to one side of the lifting frame 300 , so that the first secondary chain 231 can pull up the lifting frame 300 .

[0098] The second secondary chain 232 is meshedly connected with the second driven sprocket 243 and the third driven sprocket 241 . One end of the second secondary chain 232 is connected to the main chain 230 , and the other end is connected to the opposite side of the lifting frame 300 , so that the second secondary chain 232 can pull up the lifting frame 300 .

[0099] The fourth motor 210 is connected to the frame 100 by screw installation, and the fourth motor 210 is transmission-connected to the driving sprocket 211. Specifically, the fourth motor 210 can be connected to the transmission shaft equipped with the driving sprocket 211 by gear transmission or shaft connection.

[0100] When the output shaft of the fourth motor 210 rotates clockwise, the first and second sub-chains 231 and 232 apply a pulling force to both sides of the lifting frame 300, driving the lifting frame 300 to rise, while the counterweight 220 descends; when the output shaft of the fourth motor 210 rotates counterclockwise, the main chain 230 applies a pulling force to the counterweight 220, driving the counterweight 220 to rise, while the lifting frame 300 descends.

[0101] By adopting the above method, the load on the fourth motor 210 can be reduced, and energy consumption can be greatly saved. Of course, a hydraulic cylinder can also be used to drive the lifting frame 300. Alternatively, two sprockets, a chain meshing with the two sprockets, and a motor are provided, and the two ends of the chain are respectively connected to the top and the bottom of the lifting frame 300. When the motor drives one of the sprockets to rotate, the lifting frame can be driven to rise or fall.

[0102] The first brick pushing mechanism 520 is connected to the lifting frame 300 . The first brick pushing mechanism 520 can move laterally relative to the lifting frame 300 . The first brick pushing mechanism 520 is connected to the first conveying mechanism 530 to push bricks to the first conveying mechanism 530 .

[0103] The second brick pushing mechanism 620 is connected to the lifting frame 300 , and the second brick pushing mechanism 620 is connected to the second conveying mechanism 630 to push the bricks to the second conveying mechanism 630 .

[0104] The structure of the first brick pushing mechanism 520 is consistent with that of the second brick pushing mechanism 620, and both include: a support seat, a push plate and a driving device. The support seat is provided with a brick support plate. The push plate is provided on the brick support plate, and the push plate can move horizontally along the length direction of the brick support plate. The driving device is installed on the support seat, and the driving device is connected to the push plate to drive the push plate to move horizontally.

[0105] like Figure 8 As shown, the first brick pushing mechanism 520 is taken as an example for description. The first brick pushing mechanism 520 includes a first support seat 528, a first driving device and a first pushing plate 522.

[0106] The first support seat 528 is provided with a first brick support plate 521, and the first brick support plate 521 can be integrally formed with the first support seat 528. The first push plate 522 is provided on the first brick support plate 521, and can move horizontally along the length direction of the first brick support plate 521 to push out a row of bricks 810 stationary on the first brick support plate 521.

[0107] The first driving device may be composed of a first driving wheel 524, a first driven wheel 525, a first clamping block 527, a first belt 526 and a first brick-pushing motor 523. The first driving wheel 524 and the first driven wheel 525 are rotatably connected to the first support seat 528, the first belt 526 is wound between the first driving wheel 524 and the first driven wheel 525, the first clamping block 527 is fixed to the first belt 526, and the first clamping block 527 is connected to the first push plate 522 by screws. The first brick-pushing motor 523 is a forward and reverse motor, which can cause the first clamping block 527 to move back and forth along the length direction of the first brick support plate 521, so as to realize the pushing and resetting of the brick 810 by the first push plate 522.

[0108] Of course, the push plate can also be driven by a linear module or a motor-driven lead screw.

[0109] The driving mechanism 400 is connected to the lifting frame 300 , and the driving mechanism 400 is connected to the first brick pushing mechanism 520 to drive the first brick pushing mechanism 520 to move in the lateral direction to approach the brick 810 .

[0110] like Figure 7 As shown, specifically, the driving mechanism 400 includes: a connecting guide rail 450 , a slider 420 , a chain 430 , a moving seat 440 and a third motor 410 .

[0111] The connecting rail 450 is arranged horizontally and connected to the lifting frame 300 by screws. The connecting rail 450 can be arranged above the first brick pushing mechanism 520. The cross-sectional shape of the connecting rail 450 can be T-shaped, circular or other shapes.

[0112] The slider 420 is connected to the connecting rail 450 and can move laterally along the connecting rail 450. The slider 420 can be arranged on the lower side of the connecting rail 450, and the cross-sectional shape of the connecting rail 450 can be T-shaped, circular or other shapes, so that the slider 420 can not only slide quickly along the connecting rail 450, but also will not be easily separated from the connecting rail 450.

[0113] The two ends of the chain 430 can be connected to the lifting frame 300 by welding or other methods, so that the chain 430 is fixed horizontally. The chain 430 is located below the connecting guide rail 450 and is parallel to the connecting guide rail 450.

[0114] The movable seat 440 is connected to the slider 420 by screws, and the first brick pushing mechanism 520 is connected to the bottom of the movable seat 440 by bolts. The movable seat 440 is provided with a sprocket set, and the sprocket set is meshed and connected with the chain 430. The sprocket set includes a first sprocket 461, a second sprocket 462, and a third sprocket 463. The first sprocket 461 and the third sprocket 463 mainly play a role in tensioning the chain, so that the chain 430 can be tightly meshed with the second sprocket 462, and the second sprocket 462 is a driving wheel. Through the active rotation of the second sprocket 462, the movable seat 440 can move back and forth along the chain 430.

[0115] The third motor 410 is installed on the moving seat 440 . The third motor 410 can be connected to the second sprocket 462 of the sprocket set through a speed reducer, thereby driving the moving seat 440 to move laterally along the chain 430 .

[0116] The brick turning mechanisms are respectively disposed on the first brick pushing mechanism 520 and the second brick pushing mechanism 620 to drive each row of bricks on the kiln car 800 to turn over to the first brick pushing mechanism 520 and the second brick pushing mechanism 620 accordingly.

[0117] Specifically, the brick-turning mechanism includes: a mounting seat, a rotating shaft, a brick-turning rod and a second motor.

[0118] The mounting seat is fixedly arranged and connected to the supporting seat, so that a brick turning mechanism is installed on each of the first brick pushing mechanism 520 and the second brick pushing mechanism 620, that is, a first brick turning mechanism 510 is arranged on the first brick pushing mechanism 520, and a second brick turning mechanism 610 is arranged on the second brick pushing mechanism 620.

[0119] The rotating shaft is connected to the mounting seat through a bearing seat, and the rotating shaft can rotate around its horizontal axis.

[0120] One end of the brick-turning rod is connected to the rotating shaft, and the brick-turning rod is arranged at intervals along the axial direction of the rotating shaft; the brick-turning rod is located above the push plate, and the brick-turning rod rotates with the rotating shaft, and the other end of the brick-turning rod exerts a force on the brick, causing the brick to tip over and fall onto the brick support plate.

[0121] The second motor is connected to the mounting seat via bolts, and the second motor can be transmission-connected to the rotating shaft via a speed reducer.

[0122] like Figure 6As shown, the first brick turning mechanism 510 is used as an example for explanation. The first brick turning mechanism 510 includes a first mounting seat, a first drive motor 511, a first rotating shaft 512 and a first brick turning rod 513. The first mounting seat is fixed to the first brick pushing mechanism 520. The first rotating shaft 512 is rotatably arranged on the first mounting seat, and the first drive motor 511 is installed on the first mounting seat and is connected to the first rotating shaft 512 through a reducer to drive the first rotating shaft 512 to rotate.

[0123] The first brick-turning rods 513 may be evenly spaced along the length direction of the first rotating shaft 512 .

[0124] Furthermore, a plurality of first brick turning rods 513 may be arranged around the circumference of the first rotating shaft 512 at even intervals. Figure 7 shown.

[0125] Preferably, the brick-turning rod is a rubber strip. A plurality of connecting rods can be provided on the rotating shaft by welding, and the rubber strip is fixed on the corresponding connecting rods by screws to achieve the connection between the rubber strip and the rotating shaft. The use of the rubber strip as the brick-turning rod can ensure that the bricks are turned over when the rubber strip exerts a force, while preventing the surface appearance of the bricks from being damaged, thereby reducing the scrap rate of the bricks.

[0126] like Figure 1 , Figure 3 As shown, after the kiln car 800 is in place, it is locked to stop the kiln car 800, which facilitates the operation of the efficient automatic brick unloading machine. Under the operation of the driving mechanism 400, the first brick turning mechanism 510 and the first brick pushing mechanism 520 approach the brick 810; at this time, the length direction of the brick is arranged along the longitudinal direction, and it is easy to be turned over by the first brick turning mechanism 510.

[0127] The first brick-turning mechanism 510 applies a downward slanting thrust to a whole row of bricks 810, causing the bricks 810 to tip from a vertical state to a horizontal state and fall onto the first brick-pushing mechanism 520. The first brick-pushing mechanism 520 pushes the row of bricks 810 one by one to the first conveying mechanism 530. When the first brick-pushing mechanism 520 is working, the first brick-turning mechanism 510 stops working, while the first conveying mechanism 530 continuously conveys the bricks 810 one by one.

[0128] After unloading a whole row of bricks, the driving mechanism 400 continues to drive the first brick turning mechanism 510 and the first brick pushing mechanism 520 to approach the bricks 810, unloading subsequent rows of bricks, and finally unloading a whole layer of horizontally arranged bricks.

[0129] like Figure 2 , Figure 4As shown, after the first brick pushing mechanism 520 completes its work, the lifting frame 300 descends under the action of the lifting mechanism 200, and then the guide wheel 110 provided on the frame 100 moves on the first guide rail 120, so that the frame 100 moves longitudinally, thereby prompting the second brick pushing mechanism 620 and the second brick turning mechanism 610 to approach the brick 810; at this time, the length direction of the brick is arranged horizontally, and it is easy to be turned over by the second brick turning mechanism 610.

[0130] The second brick-turning mechanism 610 applies a downward slanting thrust to a whole row of bricks 810, causing the bricks 810 to tip from a vertical position to a horizontal position and fall onto the second brick-pushing mechanism 620. The second brick-pushing mechanism 620 pushes the row of bricks 810 one by one to the second conveying mechanism 630. When the second brick-pushing mechanism 620 is working, the second brick-turning mechanism 610 stops working, while the second conveying mechanism 630 continuously conveys the bricks 810 one by one.

[0131] After unloading a whole row of bricks, the frame 100 continues to move longitudinally, causing the second brick pushing mechanism 620 and the second brick turning mechanism 610 to approach the bricks 810, unloading subsequent rows of bricks, and finally unloading a whole layer of longitudinally arranged bricks.

[0132] The efficient automatic brick unloading machine can continuously repeat the above work to unload the staggered stacked bricks (that is, the upper and lower layers of bricks are arranged horizontally or vertically respectively) on the kiln car 800 one by one, without the need for manual unloading of bricks, thereby greatly improving efficiency.

[0133] like Figure 3 , Figure 4 As shown, in some embodiments, the first conveying mechanism 530 is connected to the lifting frame 300, so that the first conveying mechanism 530 is fixed relative to the lifting frame 300 and can move up and down therewith. The conveying direction of the first conveying mechanism 530 is set in the horizontal direction, and the brick pushing direction of the first brick pushing mechanism 520 is set in the longitudinal direction.

[0134] The second conveying mechanism 630 is connected to the lifting frame 300 so that the second conveying mechanism 630 is fixed relative to the lifting frame 300 and can move up and down accordingly. The conveying direction of the second conveying mechanism 630 is set longitudinally, while the pushing direction of the second brick pushing mechanism 620 is set transversely.

[0135] Furthermore, the second conveying mechanism 630 is vertically connected to the first conveying mechanism 530 .

[0136] The first conveying mechanism 530 and the second conveying mechanism 630 are arranged on the lifting frame 300, and can move up and down with the lifting frame 300; moreover, the first conveying mechanism 530 and the second conveying mechanism 630 are vertically connected, so that the bricks 810 unloaded by the first brick pushing mechanism 520 and the second brick pushing mechanism 620 can be uniformly conveyed out from the outlet end of the first conveying mechanism 530 or the second conveying mechanism 630, without setting up multiple conveying mechanisms to connect with the first conveying mechanism and the second conveying mechanism respectively, thereby greatly reducing enterprise costs.

[0137] In this embodiment, the first conveying mechanism 530 transfers the bricks 810 to the second conveying mechanism 630, and then docks with a conveyor at the exit of the second conveying mechanism 630, and the staff transfers the bricks on one side of the conveyor.

[0138] Of course, in other embodiments, conveyors may be provided corresponding to the first conveying mechanism 530 and the second conveying mechanism 630. In addition, the conveying direction of the first conveying mechanism 530 may be consistent with or perpendicular to the brick pushing direction of the first brick pushing mechanism 520. The conveying direction of the second conveying mechanism 630 may be consistent with or perpendicular to the brick pushing direction of the second brick pushing mechanism 620.

[0139] like Fig. 9 As shown, in some embodiments, the high-efficiency automatic brick unloading machine also includes: a third conveying mechanism 900 and a fourth conveying mechanism 700.

[0140] The bottom of the third conveying mechanism 900 is provided with a running wheel 910. Preferably, a guide rail is provided on the ground, and the running wheel 910 is provided on the guide rail, so that the third conveying mechanism 900 can move along the guide rail.

[0141] One end of the fourth conveying mechanism 700 is connected to the lifting frame 300, and the other end of the fourth conveying mechanism 700 is connected to the third conveying mechanism 900. The second conveying mechanism 630, the fourth conveying mechanism 700 and the third conveying mechanism 900 are connected in sequence and have the same conveying direction.

[0142] The fourth conveying mechanism 700 and the third conveying mechanism 900 are sequentially arranged at the exit end of the second conveying mechanism 630, so that the unloaded bricks are moved to the third conveying mechanism 900 through the fourth conveying mechanism 700, so that the staff can take away the bricks or transfer the bricks by transfer. The bottom of the third conveying mechanism 900 is provided with a running wheel 910, so that when the frame 100 moves longitudinally or the lifting frame 300 moves vertically, the inclination state of the fourth conveying mechanism 700 will inevitably change, which will affect the third conveying mechanism 900. The running wheel 910 can adjust the longitudinal position of the third conveying mechanism 900, so that the third conveying mechanism 900, the fourth conveying mechanism 700 and the lifting frame 300 can still maintain a stable connection, thereby ensuring that the brick unloading work can proceed normally.

[0143] Furthermore, the conveying directions of the second conveying mechanism 630, the fourth conveying mechanism 700 and the third conveying mechanism 900 are consistent and are all arranged in the longitudinal direction, which not only makes it convenient for the staff to transfer bricks on one side, but also improves the efficiency of brick conveying.

[0144] Of course, the conveying direction of the fourth conveying mechanism 700 can also be vertically connected to the second conveying mechanism 630 and the third conveying mechanism 900, respectively. However, the conveying speed of bricks is affected to a certain extent during the process of transferring the bricks from the second conveying mechanism 630 to the fourth conveying mechanism 700 at a right angle and from the fourth conveying mechanism 700 to the third conveying mechanism 900 at a right angle.

[0145] Preferably, the first conveying mechanism 530, the second conveying mechanism 630, the third conveying mechanism 900 and the fourth conveying mechanism 700 are belt conveyors. In addition, baffles or skirts may be provided on the outside of the first conveying mechanism 530 and the second conveying mechanism 630, and baffles or skirts may be provided on both sides of the third conveying mechanism 900 and the fourth conveying mechanism 700, so as to prevent bricks from falling.

[0146] Of course, the first conveying mechanism 530 , the second conveying mechanism 630 , the third conveying mechanism 900 , and the fourth conveying mechanism 700 may also be roller conveyors or chain conveyors.

[0147] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
