Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a material unloading device capable of automatically adjusting belt deviation. Background Art

[0002] Belt conveyor is a kind of continuous material transportation equipment with the characteristics of low noise, large transportation capacity and low maintenance. Belt conveyor is often used for the transportation and transfer of bulk materials. At present, the transfer of materials between belt conveyors adopts funnel transition to reduce the impact of material transfer on the belt conveyor.

[0003] In the related art, a Chinese patent with authorization announcement number CN207566421U provides an assembled belt conveyor head funnel, which includes a funnel upper cover, a lower funnel and a front side plate installed at the bottom of the funnel upper cover, the front side plate installed on one side of the lower funnel, and a stacking plate and a lining plate installed on the side of the front side plate facing the lower funnel. After the material enters the funnel upper cover, it falls downward. When the material falls into the lower funnel and the front side plate, the material hits the stacking plate, and the stacking plate buffers the incoming material, reducing the impact of the direct fall of the material on the belt conveyor.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: during the bulk material conveying process, the material has a large fluidity. When the material falls from the funnel to the belt conveyor, the loose material will accumulate on one side of the belt, causing the belt on the belt conveyor to deviate. The deviated belt is prone to material spillage during the material transportation process. Utility Model Content

[0005] In order to reduce the situation where materials are spilled due to belt deviation, the present application provides a material unloading device that can automatically adjust the belt deviation.

[0006] The present application provides a feeding device capable of automatically adjusting belt deviation, which adopts the following technical solution:

[0007] A material unloading device capable of automatically adjusting belt deviation comprises a hopper, wherein a left guide plate and a right guide plate are rotatably arranged inside the hopper, the left guide plate and the right guide plate are arranged opposite to each other, a left driving assembly is arranged on the side of the left guide plate away from the right guide plate, the left driving assembly is used to drive the left guide plate to rotate, a right driving assembly is arranged on the side of the right guide plate away from the left guide plate, the right driving assembly is used to drive the right guide plate to rotate, a trigger assembly is arranged on the hopper, and the trigger assembly is used to control the actions of the left driving assembly and the right driving assembly.

[0008] By adopting the above technical solution, the material falls downward after entering the hopper. Under normal belt conditions, the left guide plate and the right guide plate are symmetrically arranged in the hopper, and the material continues to slide downward along the left guide plate and the right guide plate. The left guide plate and the right guide plate buffer the incoming material and reduce the impact of the material on the belt. When the material landing point is biased to the left side of the belt, the belt is affected by the weight of the material and deviates to the right side. When the belt deviates to the right side to a certain extent, the trigger component activates the left drive component and the right drive component. The left drive component rotates the left guide plate upward, and the right drive component rotates the right guide plate downward, thereby causing the landing point to deviate to the right side of the belt. Under the influence of the weight of the material, it gradually returns to the right side. When the material landing point is biased to the right side of the belt, the belt is affected by the weight of the material, causing the belt to deviate to the left side. When the belt deviates to the left side to a certain extent, the trigger component activates the left drive component and the right drive component. The left drive component rotates the left guide plate downward, and the right drive component rotates the right guide plate upward, thereby causing the landing point to deviate to the left side of the belt. Under the influence of the weight of the material, the belt gradually returns to the right side. After the belt returns to the right side, the trigger component activates the left drive component and the right drive component. The left drive component resets the left guide plate, and the right drive component resets the right guide plate, thereby reducing the situation where the belt deviates and causes material spillage.

[0009] Preferably, ceramic lining plates are provided on the opposite surfaces of the left guide plate and the right guide plate.

[0010] By adopting the above technical solution, the material collides with the ceramic lining plate, thereby reducing the wear of the material on the left guide plate and the right guide plate.

[0011] Preferably, the trigger assembly includes a left light emitter and a left photosensor, the left photosensor is arranged on one side of the hopper, the left light emitter is arranged directly below the left photosensor, and the left drive assembly and the right drive assembly are both connected to the left photosensor.

[0012] By adopting the above technical solution, when the belt is in normal condition, the belt will block the left light emitter, and the left photosensor cannot detect the light source emitted by the left light emitter. When the material falls on the left side of the belt, the belt is affected by the weight of the material, causing the belt to shift to the right. When the belt shifts to the right to a certain extent, the belt will expose the left light emitter, and the left photosensor detects the light source emitted by the left light emitter, thereby triggering the left drive assembly and the right drive assembly to move. When the belt gradually returns to the normal state under the influence of the material weight, when the belt blocks the left light emitter again, the left photosensor cannot detect the light source emitted by the left light emitter. At this time, the left guide plate is reset under the action of the left drive assembly, and the right guide plate is reset under the action of the right drive assembly.

[0013] Preferably, the trigger assembly includes a right light emitter and a right photosensor, the right photosensor is arranged on the other side of the hopper, the right light emitter is arranged directly below the right photosensor, and the left drive assembly and the right drive assembly are both connected to the right photosensor.

[0014] By adopting the above technical solution, when the belt is in normal condition, the belt will block the right light emitter, and the right photosensor cannot detect the light source emitted by the right light emitter. When the material falls on the right side of the belt, the belt is affected by the weight of the material, causing the belt to shift to the left. When the belt shifts to the left to a certain extent, the belt will expose the right light emitter, and the right photosensor will detect the light source emitted by the right light emitter, thereby triggering the left drive assembly and the right drive assembly to move. When the belt gradually returns to the normal state under the influence of the material weight, when the belt blocks the right light emitter again, the right photosensor cannot detect the light source emitted by the right light emitter. At this time, the left guide plate is reset under the action of the left drive assembly, and the right guide plate is reset under the action of the right drive assembly.

[0015] Preferably, the left drive assembly includes several left hydraulic cylinders, the left photosensor and the right photosensor are electrically connected to the left hydraulic cylinder, a left support frame is commonly arranged on the left hydraulic cylinder, the left support frame is fixedly arranged in the hopper, and the output shaft of the left hydraulic cylinder is arranged toward the left guide plate.

[0016] By adopting the above technical solution, when the belt is normal, the output shaft of the left hydraulic cylinder extends a part, so that the left guide plate is tilted in the hopper. When the left photosensor detects the light emitted by the left light emitter, the output shaft of the left hydraulic cylinder is fully extended, so that the left guide plate rotates upward, thereby causing the material landing point to move to the right side of the belt. When the right photosensor detects the light emitted by the right light emitter, the output shaft of the left hydraulic cylinder is fully retracted, so that the left guide plate rotates downward, thereby causing the material landing point to move to the left side of the belt.

[0017] Preferably, a left connecting groove is provided on a side of the left guide plate away from the right guide plate, a left connecting block is slidably arranged in the left connecting groove, and the left connecting block is rotationally connected to the output shaft of the left hydraulic cylinder.

[0018] By adopting the above technical solution, the left guide plate and the output shaft of the left hydraulic cylinder are connected through the left connecting block. When the output shaft of the left hydraulic cylinder moves, the output shaft of the left hydraulic cylinder drives the left connecting block to move along the left connecting groove. At the same time, the left connecting block and the output shaft of the left hydraulic cylinder rotate, thereby achieving the effect of the left hydraulic cylinder driving the left guide plate to rotate.

[0019] Preferably, the right drive assembly includes several right hydraulic cylinders, the left photosensitive sensor and the right photosensitive sensor are electrically connected to the right hydraulic cylinder, a right support frame is commonly arranged on the right hydraulic cylinder, the right support frame is fixedly arranged in the hopper, and the output shaft of the right hydraulic cylinder is arranged toward the right guide plate.

[0020] By adopting the above technical solution, when the belt is normal, the output shaft of the right hydraulic cylinder extends a part, so that the right guide plate is tilted in the hopper. When the left photosensor detects the light emitted by the left light emitter, the output shaft of the right hydraulic cylinder is fully retracted, so that the right guide plate rotates downward, thereby causing the material landing point to move to the right side of the belt. When the right photosensor detects the light emitted by the right light emitter, the output shaft of the right hydraulic cylinder is fully extended, so that the right guide plate rotates upward, thereby causing the material landing point to move to the left side of the belt.

[0021] Preferably, a right connecting groove is provided on a side of the right guide plate away from the left guide plate, a right connecting block is slidably arranged in the right connecting groove, and the right connecting block is rotationally connected to the output shaft of the right hydraulic cylinder.

[0022] By adopting the above technical solution, the right guide plate and the output shaft of the right hydraulic cylinder are connected through the right connecting block.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a feeding device that can automatically adjust the belt deviation. Figure 1, which includes a hopper 1, which is installed above a belt 8. A left guide plate 2 and a right guide plate 3 are installed in the hopper 1, and the left guide plate 2 and the right guide plate 3 are rotatably connected to the inner wall of the hopper 1 through a rotating shaft, and the left guide plate 2 and the right guide plate 3 are arranged opposite to each other, and ceramic lining plates 4 are installed on the opposite surfaces of the left guide plate 2 and the right guide plate 3. A left drive assembly 5 is installed on the side of the left guide plate 2 away from the right guide plate 3, and the left drive assembly 5 is installed on the inner wall of the hopper 1, and the left drive assembly 5 is used to drive the left guide plate 2 to rotate. A right drive assembly 6 is installed on the side of the right guide plate 3 away from the left guide plate 2, and the right drive assembly 6 is installed on the inner wall of the hopper 1, and the right drive assembly 6 is used to drive the right guide plate 3 to rotate. A trigger assembly 7 is installed on the outer wall of the hopper 1, and the trigger assembly 7 is used to control the actions of the left drive assembly 5 and the right drive assembly 6. After the material enters the hopper 1, it falls downward. Under normal conditions of the belt 8, the left guide plate 2 and the right guide plate 3 are symmetrically arranged in the hopper 1. The material collides with the ceramic lining plate 4. The left guide plate 2 and the right guide plate 3 buffer the incoming material, reducing the impact of the material on the belt 8. At the same time, the ceramic lining plate 4 reduces the wear of the material on the left guide plate 2 and the right guide plate 3. When the material falls to the left side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the right. When the belt 8 deviates to the right to a certain extent, the trigger component 7 activates the left drive component 5 and the right drive component 6. The left drive component rotates the left guide plate 2 counterclockwise, and the right drive component rotates the right guide plate 3 counterclockwise, thereby causing the material falling point to deviate to the right side of the belt 8. The belt 8 gradually returns to the right under the influence of the material weight. When the material falls to the right side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the left. When the belt 8 deviates to the left to a certain extent, the trigger assembly 7 activates the left drive assembly 5 and the right drive assembly 6, the left drive assembly rotates the left guide plate 2 clockwise, and the right drive assembly rotates the right guide plate 3 clockwise, thereby causing the material drop point to deviate to the left side of the belt 8, and the belt 8 gradually returns to the right under the influence of the material weight. When the belt 8 returns to the right, the trigger assembly 7 activates the left drive assembly 5 and the right drive assembly 6, the left drive assembly resets the left guide plate 2, and the right drive assembly resets the right guide plate 3, thereby reducing the situation where the belt 8 deviates and causes the material to spill.

[0033] In order to control the left drive assembly 5 and the right drive assembly 6, refer to Figure 1The trigger assembly 7 includes a left light emitter 72, a left photosensitive sensor 71, a right light emitter 74 and a right photosensitive sensor 73. The left photosensitive sensor 71 is installed on one side of the hopper 1, and the right photosensitive sensor 73 is installed on the other side of the hopper 1. The left light emitter 72 is installed directly below the left photosensitive sensor 71, and the right light emitter 74 is installed directly below the right photosensitive sensor 73. The left drive assembly 5 and the right drive assembly 6 are both electrically connected to the left photosensitive sensor 71 and the right photosensitive sensor 73. There is an installation gap between the left light emitter 72 and the left photosensitive sensor 71, and the installation gap is located between the right light emitter 74 and the right photosensitive sensor 73. The belt 8 is set in the installation gap, and the belt 8 blocks the left light emitter 72 and the right light emitter 74. When the belt 8 is in a normal condition, the belt 8 blocks the left light emitter 72 and the right light emitter 74. At this time, the left photosensitive sensor 71 cannot detect the light source emitted by the left light emitter 72, and the right photosensitive sensor 73 cannot detect the light source emitted by the right light emitter 74. When the material falls on the left side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the right. When the belt 8 deviates to the right to a certain extent, the belt 8 exposes the left light emitter 72, and the left photosensitive sensor 71 detects the light emitted by the left light emitter 72. Then the left drive assembly 5 and the right drive assembly 6 are triggered to act, and the belt 8 gradually returns to the right under the influence of the weight of the material. During the gradual return of the belt 8, when the belt 8 blocks the left light emitter 72 again, the left photosensitive sensor 71 cannot detect the light emitted by the left light emitter 72. At this time, the left guide plate 2 is reset under the action of the left drive assembly 5, and the right guide plate 3 is reset under the action of the right drive assembly 6. When the material falls on the right side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the left. When the belt 8 deviates to the left to a certain extent, the belt 8 exposes the right light emitter 74, and the right photosensitive sensor 73 detects the light emitted by the right light emitter 74. Then the left drive assembly 5 and the right drive assembly 6 are triggered to act, and the belt 8 gradually returns to the right under the influence of the weight of the material. During the process of the belt 8 gradually returning to the correct position, when the belt 8 blocks the right light emitter 74 again, the right photosensor 73 cannot detect the light source emitted by the right light emitter 74. At this time, the left guide plate 2 is reset under the action of the left drive assembly 5, and the right guide plate 3 is reset under the action of the right drive assembly 6.

[0034] In order to achieve the effect of driving the left guide plate 2 to rotate, refer to Figure 1 and Figure 2The left driving assembly 5 includes a plurality of left hydraulic cylinders 51, and the left photosensitive sensor 71 and the right photosensitive sensor 73 are both electrically connected to the left hydraulic cylinder 51. The left support frame 511 is installed on the left hydraulic cylinder 51, and the left support frame 511 is welded in the hopper 1, and the output shaft of the left hydraulic cylinder 51 is arranged toward the left guide plate 2. A left connecting groove 21 is provided on the side of the left guide plate 2 away from the right guide plate 3, and a left connecting block 512 is slidably arranged in the left connecting groove 21, and the left connecting block 512 is rotatably connected to the output shaft of the left hydraulic cylinder 51. When the output shaft of the left hydraulic cylinder 51 moves, the output shaft of the left hydraulic cylinder 51 drives the left connecting block 512 to move along the left connecting groove 21, and at the same time, the left connecting block 512 and the output shaft of the left hydraulic cylinder 51 rotate, thereby achieving the effect that the left hydraulic cylinder 51 drives the left guide plate 2 to rotate. When the belt 8 is normal, a part of the output shaft of the left hydraulic cylinder 51 extends, so that the left guide plate 2 is tilted in the hopper 1. When the left photosensor 71 detects the light emitted by the left light emitter 72, the output shaft of the left hydraulic cylinder 51 is fully extended, causing the left guide plate 2 to rotate counterclockwise, thereby causing the material landing point to move to the right side of the belt 8. When the right photosensor 73 detects the light emitted by the right light emitter 74, the output shaft of the left hydraulic cylinder 51 is fully retracted, causing the left guide plate 2 to rotate clockwise, thereby causing the material landing point to move to the left side of the belt 8.

[0035] In order to achieve the effect of driving the right guide plate 3 to rotate, refer to Figure 1 and Figure 3 The right driving assembly 6 includes a plurality of right hydraulic cylinders 61, and the left photosensitive sensor 71 and the right photosensitive sensor 73 are both electrically connected to the right hydraulic cylinder 61. A right support frame 611 is installed on the right hydraulic cylinder 61, and the right support frame 611 is welded in the hopper 1, and the output shaft of the right hydraulic cylinder 61 is arranged toward the right guide plate 3. A right connecting groove 31 is provided on the side of the right guide plate 3 away from the left guide plate 2, and a right connecting block 612 is slidably arranged in the right connecting groove 31, and the right connecting block 612 is rotatably connected to the output shaft of the right hydraulic cylinder 61. When the output shaft of the right hydraulic cylinder 61 moves, the output shaft of the right hydraulic cylinder 61 drives the right connecting block 612 to move along the right connecting groove 31, and at the same time, the right connecting block 612 and the output shaft of the right hydraulic cylinder 61 rotate, thereby achieving the effect that the right hydraulic cylinder 61 drives the right guide plate 3 to rotate. When the belt 8 is normal, a part of the output shaft of the right hydraulic cylinder 61 extends out, so that the right guide plate 3 is tiltedly arranged in the hopper 1. When the left photosensor 71 detects the light from the left light emitter 72, the output shaft of the right hydraulic cylinder 61 is completely retracted, causing the right guide plate 3 to rotate clockwise, thereby causing the material landing point to move to the right side of the belt 8. When the right photosensor 73 detects the light from the right light emitter 74, the output shaft of the right hydraulic cylinder 61 is completely extended, causing the right guide plate 3 to rotate counterclockwise, thereby causing the material landing point to move to the left side of the belt 8.

[0036] The implementation principle of a material unloading device capable of automatically adjusting the deviation of the belt in the embodiment of the present application is as follows: when the belt 8 is normal, the belt 8 blocks the left light emitter 72 and the right light emitter 74. At this time, a part of the output shaft of the left hydraulic cylinder 51 extends out, so that the left guide plate 2 is tilted and set in the hopper 1, and a part of the output shaft of the right hydraulic cylinder 61 extends out, so that the right guide plate 3 is tilted and set in the hopper 1, and then the left guide plate 2 and the right guide plate 3 are symmetrically arranged in the hopper 1, and the left guide plate 2 and the right guide plate 3 buffer the incoming material to reduce the impact of the material on the belt 8. When the material falls to the left side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the right. When the belt 8 deviates to the right to a certain extent, the belt 8 exposes the left light emitter 72, and the left photosensitive sensor 71 detects the light source emitted by the left light emitter 72. When the left photosensitive sensor 71 detects the light source emitted by the left light emitter 72, the output shaft of the left hydraulic cylinder 51 is fully extended, and the output shaft of the right hydraulic cylinder 61 is fully retracted, so that the left guide plate 2 and the right guide plate 3 rotate counterclockwise, thereby causing the material landing point to move to the right side of the belt 8, and the belt 8 gradually returns to the right under the influence of the material weight. During the gradual return of the belt 8, when the belt 8 blocks the left light emitter 72 again, the left photosensitive sensor 71 cannot detect the light source emitted by the left light emitter 72, and the left guide plate 2 and the right guide plate 3 are reset. When the material landing point is biased to the right side of the belt 8, the belt 8 is affected by the weight of the material, causing the belt 8 to deviate to the left. When the belt 8 deviates to the left to a certain extent, the belt 8 exposes the right light emitter 74, and the right photosensitive sensor 73 detects the light source emitted by the right light emitter 74. When the right photosensitive sensor 73 detects the light source emitted by the right light emitter 74, the output shaft of the left hydraulic cylinder 51 is completely retracted, and the output shaft of the right hydraulic cylinder 61 is completely extended, so that the left guide plate 2 and the right guide plate 3 rotate clockwise, thereby causing the material landing point to move to the left side of the belt 8, and the belt 8 gradually returns to the right position under the influence of the weight of the material. During the gradual return of the belt 8, when the belt 8 blocks the right light emitter 74 again, the right photosensitive sensor 73 cannot detect the light source emitted by the right light emitter 74, and the left guide plate 2 and the right guide plate 3 are reset at this time. When the belt 8 deviates, the position of the material landing point is adjusted in time by the cooperation between the left guide plate 2 and the right guide plate 3, thereby achieving the effect of timely correcting the belt 8 and reducing the situation where the belt 8 deviates and causes the material to spill.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
