Description

Technical Field

[0001] This utility model relates to the field of material transportation and transfer equipment, and in particular to a buffer device for a multi-level transportation system. Background Technology

[0002] In mining and material transportation, due to limitations in the capacity of transportation equipment and the discontinuous nature of mining operations, the entire transportation system cannot achieve effective coordination, leading to problems such as idle transport and wasted transport capacity. In multi-level transportation systems or situations involving transshipment, storage silos are often used for temporary material storage. However, existing transportation systems typically use separate storage chambers that only serve mechanical fixed storage and feeding functions. This results in a mismatch between storage and feeding capacity and the transport system's capacity, and also inconveniences for material input and output. Utility Model Content

[0003] This utility model aims to solve the above problems and provides a buffer device for a multi-level transportation system, the technical solution of which is as follows:

[0004] A buffer device for a multi-stage transport system includes a storage bin, an unloading mechanism, and a discharge mechanism. The storage bin is located below the conveyor belt, and the unloading mechanism is located above the conveyor belt. The unloading mechanism includes an unloading plow, which operates at a high or low position under the action of the unloading mechanism. When in the high position, the unloading plow does not interfere with the material on the conveyor belt; when in the low position, the unloading plow is in close contact with the conveyor belt, and the material on the conveyor belt is blocked by the unloading plow and falls into the storage bin. The discharge mechanism includes a discharge movable plate, which is hinged to the bottom of the storage bin. When the discharge movable plate is tilted downwards, the discharge port is exposed.

[0005] Based on the above scheme, the unloading mechanism also includes an unloading fixing frame, an unloading side guard plate, and a plow head cylinder. The unloading fixing frame and the unloading side guard plate are fixedly connected to the storage bin. The unloading side guard plate is set on opposite sides of the conveyor belt, and the lower edge of the unloading side guard plate extends into the storage bin. One side of the unloading plow head is hinged to the unloading fixing frame. The cylinder barrel and piston rod of the plow head cylinder are respectively hinged to the top of the unloading fixing frame and the middle of the unloading plow head.

[0006] Based on the above scheme, the side of the unloading plow is an inclined baffle, and the angle between the inclined direction of the inclined baffle and the conveying direction of the conveyor belt is an acute angle; a side baffle is provided on the side of the inclined baffle near the unloading fixed frame, and the side baffle extends outward in a direction parallel to the conveyor belt.

[0007] Based on the above scheme, the number of inclined baffles is two, and they are symmetrically arranged in the horizontal plane.

[0008] Preferably, a flat idler roller is provided below the unloading plow, and the height of the flat idler roller is not lower than the highest height of the load-bearing idler roller below the conveyor belt.

[0009] Based on the above scheme, a transition roller is provided between the flat roller and the load-bearing rollers on both sides. The transition roller is not higher than the flat roller, and the middle of the transition roller is suspended.

[0010] Preferably, the system also includes a flow monitor, which is positioned above the conveyor belt and used to detect the flow rate of material being transported on the conveyor belt.

[0011] Preferably, the device also includes a material storage scanner, which is positioned above the storage silo and used to detect the amount of material stored in the silo.

[0012] Preferably, the discharge mechanism further includes a discharge cylinder, a support leg is fixedly connected below the storage bin, and the two ends of the discharge cylinder are respectively hinged to the support leg and the discharge movable plate.

[0013] Preferably, the discharge mechanism further includes a discharge baffle, which is arranged longitudinally and is located on opposite sides of the discharge port with the discharge movable plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The storage bin is located below the conveyor belt, allowing materials to be pushed from the conveyor belt into the storage bin as needed for easy transfer; a discharge mechanism is installed below the storage bin to directly control the material discharge action; facilitating the storage and discharge of materials.

[0016] 2. The unloading mechanism controls the height of the unloading plow head through the plow head cylinder, switching between the conveying and material storage functions of the conveying system. The switching is simple and time-saving, and the storage efficiency is high.

[0017] 3. By setting up flow monitors and material storage scanners, the material transportation and storage conditions in the conveyor belt and storage bins can be monitored in real time, thereby adjusting the incoming material from the upper-level conveying device and the outgoing material from the storage bin in a timely manner, thus meeting the transportation requirements of adjusting transportation and storage strategies in a timely manner according to the actual transportation volume.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In the description of this utility model, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figures 1 to 4 As shown, a buffer device for a multi-stage transport system includes a storage bin 11, an unloading mechanism, and a discharge mechanism. The storage bin 11 is located below the conveyor belt. Specifically, the storage bin 11 is located below the idler frame 21, and the idler frame 21 is provided with a support idler 22 for supporting the conveyor belt.

[0027] The unloading mechanism is located above the conveyor belt. The unloading mechanism includes an unloading plow 33. The unloading plow 33 works at a high position or a low position under the action of the unloading mechanism. When it is at a high position, the unloading plow 33 does not interfere with the material on the conveyor belt. When it is at a low position, the unloading plow 33 is in close contact with the conveyor belt. The material on the conveyor belt is blocked by the unloading plow 33 and falls into the storage bin 11.

[0028] Specifically, the unloading mechanism further includes an unloading fixing frame 31, an unloading side guard plate 32, and a plow cylinder 34. The unloading fixing frame 31 and the unloading side guard plate 32 are fixedly connected to the storage bin 11. The unloading side guard plate 32 is arranged on opposite sides of the conveyor belt, and the lower edge of the unloading side guard plate 32 extends into the storage bin 11. One side of the unloading plow 33 is hinged to the unloading fixing frame 31. The cylinder and piston rod of the plow cylinder 34 are respectively hinged above the unloading fixing frame 31 and in the middle of the unloading plow 33. When the piston rod of the plow cylinder 34 retracts, it drives the unloading plow 33 to lift upward. At this time, the unloading plow 33 is separated from the conveyor belt and the material on it, and the conveyor belt plays its normal transportation role. When the piston rod of the plow cylinder 34 extends, it drives the unloading plow 33 to fall down to be in close contact with the conveyor belt, blocking the material on the conveyor belt and causing the material to fall into the storage bin 11 to complete material buffering. Preferably, the unloading plow 33 has an inclined baffle 331 on its side, and the angle between the inclined direction of the inclined baffle 331 and the conveying direction of the conveyor belt is an acute angle. A side baffle 332 is provided on the side of the inclined baffle 331 near the unloading fixing frame 31, and the side baffle 332 extends outward in a direction parallel to the conveyor belt. The inclined baffle 331 guides the material, allowing the material to enter the storage bin 11 more smoothly from the side. There are two inclined baffles 331, which are symmetrically arranged in the horizontal plane, so that the unloading plow 33 can adapt to the bidirectional material transportation and storage needs of the conveyor belt.

[0029] Since the supporting idler 22 is a multi-section idler, the conveyor belt moves in a U-shape on it, which is not conducive to the unloading plow 33 being fully in contact with the conveyor belt. Therefore, a flat idler 42 is provided below the unloading plow 33. The height of the flat idler 42 is not lower than the highest height of the supporting idler 22 below the conveyor belt, thereby ensuring that the conveyor belt below the unloading plow 33 remains in a flat state and there is no gap between the conveyor belt and the unloading plow 33. Preferably, a transition idler 41 is provided between the flat idler 42 and the supporting idlers 22 on both sides. The transition idler 41 is not higher than the flat idler 42, and the middle of the transition idler 41 is suspended, so that when the conveyor belt moves from the supporting idler 22 to the position between the flat idlers 42, the middle angle of the conveyor belt is transitioned at the transition idler 41, which does not affect the service life of the conveyor belt.

[0030] The discharge mechanism includes a discharge movable plate 52, which is hinged to the bottom of the storage silo 11. When the discharge movable plate 52 is tilted downwards, the discharge port is exposed. Specifically, the discharge mechanism also includes a discharge cylinder 53. A support leg 12 is fixedly connected to the bottom of the storage silo 11. The two ends of the discharge cylinder 53 are respectively hinged to the support leg 12 and the discharge movable plate 52. The angle of the discharge movable plate 52 is controlled by the movement of the discharge cylinder 53, thereby controlling the size of the discharge port opening. The discharge mechanism also includes a discharge baffle 51, which is arranged longitudinally and positioned on opposite sides of the discharge port from the discharge movable plate 52. The discharge baffle 51 prevents excessive spillage of material when discharged from the storage silo 11.

[0031] It also includes a flow monitor 61, which is installed above the conveyor belt and used to detect the flow rate of material transported on the conveyor belt. The flow monitor 61 calculates the amount of material on the conveyor belt in real time using laser scanning technology. When the actual amount of material is less than the ideal transport capacity, the upstream transportation system increases the discharge rate, and the flow monitor 61 provides feedback with a delay. When the actual amount of material is greater than the ideal transport capacity, the upstream transportation system decreases the discharge rate, and the flow monitor 61 also provides feedback with a delay, thereby improving the matching degree between the actual transport capacity and the ideal transport capacity and ensuring the full utilization of transportation capacity.

[0032] It also includes a material storage scanner 62, which is positioned above the storage silo 11, such as below the roller frame 21, and is used to detect the material level in the storage silo 11. The material storage scanner 62 calculates the material level in the storage silo 11 in real time using laser scanning technology. When the material level exceeds the rated storage capacity, it sends a full-silo signal to the central control system. The central control system then controls the discharge cylinder 53 to tilt the discharge movable plate 52, thereby discharging the material from the storage silo 11 and preventing overflow when the silo is full.

[0033] The number of buffer devices in the same level of conveying system can be multiple. Depending on the actual transportation situation, when the storage bin 11 of one of the buffer devices is full, the other buffer devices at the same level will temporarily store the materials. The buffer devices at the same level can store or unload materials in turn or in a designated manner, either sequentially or simultaneously.

[0034] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
