Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a precise positioning bulk material reversing device. Background Technology

[0002] Coal serves as a versatile basic energy source and industrial raw material. The same type of coal can be processed into thermal coal for power generation through crushing and screening, or into chemical coal for coal chemical product synthesis through washing and desulfurization. It can also be transformed into metallurgical coal to meet the needs of iron and steel smelting through molding and upgrading processes. Different types and qualities of coal need to be diverted to corresponding process paths for targeted processing based on their calorific value, ash content, sulfur content, and other indicators in order to maximize the utilization value of coal resources.

[0003] The traditional coal diversion method commonly used in the industry currently uses a drive motor to drive a reciprocating oscillating diversion plate to oscillate around a fixed axis, thereby switching coal between two fixed paths. This method has a limited number of diversion paths, and when a new process path is needed, the entire structure of the device must be modified, resulting in a long construction period and high costs. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a precise positioning bulk material reversing device, which solves the technical problem of a precise positioning bulk material reversing device in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a bulk material reversing device with precise positioning, comprising: a base; The main conveyor belt is set on the base. The main conveyor belt is equipped with two side barriers to prevent materials from falling. Both side barriers are provided with diversion ports. The conveying path of the main conveyor belt is the first diversion channel. The conveying paths corresponding to the two diversion ports are the second diversion channel and the third diversion channel, respectively. The diverter is movably mounted on the base and located above the main conveyor belt. The diverter has two spaced guide plate sections, forming an opening for material transport between the two guide plate sections. Both guide plate sections are inclined relative to the main conveyor belt and are symmetrically arranged. The bottom of the guide plate section is in contact with the main conveyor belt. The diverter is configured to be movable such that a guide plate portion blocks the first and second diverters and tilts the material of the main conveyor belt to the third diverter, or to be movable such that the opening faces the first diverter so that the material of the main conveyor belt passes through the opening and is conveyed along the first diverter.

[0006] For example, in at least one embodiment of the present invention, a bulk material reversing device with precise positioning is provided, which further includes: three diversion conveyor belts for receiving materials from the main conveyor belt, all three diversion conveyor belts being located below the main conveyor belt; The two diversion ports correspond to two diversion conveyor belts respectively, and the remaining diversion conveyor belt is placed at one end of the main conveyor belt along the conveying direction of the main conveyor belt.

[0007] For example, in a bulk material diversion device with precise positioning provided in at least one embodiment of the present invention, the diverting component has a connecting part, which is used to connect two guide plate parts and is slidably connected to the base.

[0008] For example, in a bulk material reversing device with precise positioning provided in at least one embodiment of the present invention, the connecting part is located at the bottom away from the guide plate part, and the lower part of the connecting part is a passage.

[0009] For example, in a bulk material diversion device with precise positioning provided in at least one embodiment of the present invention, the diversion component also has two baffles that can block the two diversion ports when the port faces the first diversion channel.

[0010] For example, in a bulk material reversing device with precise positioning provided in at least one embodiment of the present invention, the guide plate portion and the baffle portion form a triangular structure.

[0011] For example, in at least one embodiment of the present invention, a bulk material reversing device with precise positioning is provided, which further includes: a linear drive assembly disposed on a base for driving the connecting part to move.

[0012] For example, in at least one embodiment of this utility model, a precisely positioned bulk material reversing device includes a linear drive component comprising: The first link is located on the connecting part; The crank arm is rotatably mounted on the base, and the crank arm and the first link are hinged together by the second link.

[0013] For example, in at least one embodiment of the present invention, a bulk material reversing device with precise positioning is provided, the linear drive component further includes: A rotation drive component, mounted on the base, is used to drive the crank arm to rotate.

[0014] For example, in a precise positioning bulk material reversing device provided in at least one embodiment of this utility model, the rotation drive component drives the crank arm to rotate via a sprocket and chain.

[0015] The beneficial effects of this utility model are as follows: In this invention, the two guide plates of the diverter are arranged symmetrically and inclined, forming an opening between them. Preferably, the width of the opening is greater than or equal to the conveying width of the main conveyor belt, allowing material to pass through the opening and be conveyed along the first diverting channel corresponding to the main conveyor belt. When it is necessary to guide material to a third diverting channel corresponding to a diverting port, the diverter is moved so that one of the guide plates simultaneously blocks the end of the first diverting channel and the entrance of the second diverting channel. After the material conveyed by the main conveyor belt contacts the guide plate, it changes its direction of movement under the guidance of the inclined surface and enters the third diverting channel in the direction the guide plate is inclined, thus achieving directional diversion. When the material does not need to be diverted and needs to be conveyed along the original path, the diverter is moved so that the middle opening is aligned with the first diverting channel; the material on the main conveyor belt passes directly through the opening without being disturbed by the guide plates and continues to be conveyed along the first diverting channel to the subsequent process.

[0016] In summary, by adjusting the position of the diverter, the three paths can be switched to adapt to the processing needs of multiple coal processes in parallel. The symmetrical design of the inclined guide plate stabilizes the material flow direction, preventing skewing or accumulation, effectively reducing the loss of materials such as coal, while preventing material mixing from different paths and ensuring the purity of raw materials for subsequent processes.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-4 As shown, this invention illustrates a precise positioning bulk material reversing device according to one embodiment of the present invention. The device uses a base 100 as the installation reference, with the main conveyor belt 200 fixed on the base 100, forming the basic carrier for material conveying. The main conveyor belt 200 has integrally formed side guards 220 on both sides, with symmetrical diversion ports 230 on the side guards 220, corresponding to the second diversion channel 310 and the third diversion channel 320 respectively. The conveying path of the main conveyor belt 200 itself is defined as the first diversion channel 210. The diversion component 400 is mounted on the base 100 by sliding or guiding mechanism and is suspended directly above the main conveyor belt 200, with its bottom in contact with the surface of the main conveyor belt 200 to ensure no material leakage gap.

[0027] The two guide plate portions 420 of the diverter 400 are arranged symmetrically and inclined, forming an opening 410 between the two guide plate portions 420. Preferably, the width of the opening 410 is greater than or equal to the conveying width of the main conveyor belt 200, allowing materials to be conveyed along the first diverting channel 210 corresponding to the main conveyor belt 200 through the opening 410. When it is necessary to guide the material to the third diverting channel 320 corresponding to a diverting port 230, the diverter 400 is moved so that one of the guide plate portions 420 simultaneously blocks the end of the first diverting channel 210 and the entrance of the second diverting channel 310. After the material conveyed by the main conveyor belt 200 contacts the guide plate portion 420, it changes its direction of movement under the guidance of the inclined surface and enters the third diverting channel 320 inclined towards the guide plate portion 420, thus achieving directional diversion. When the material does not need to be diverted and needs to be conveyed along the original path, the moving diverter 400 aligns the intermediate opening 410 with the first diverting channel 210; the material of the main conveyor belt 200 passes directly through the opening 410, without being disturbed by the guide plate 420, and is continuously conveyed to the subsequent process along the first diverting channel 210.

[0028] In summary, by adjusting the position of the diverter 400, the three paths can be switched to adapt to the processing needs of multiple coal processes in parallel. The symmetrical design of the inclined guide plate 420 stabilizes the material flow direction, preventing skewing or accumulation, effectively reducing the loss of materials such as coal, while preventing material mixing from different paths and ensuring the purity of raw materials for subsequent processes.

[0029] Furthermore, three diversion conveyor belts 300 are fixed to the base 100, forming a layered layout below the main conveyor belt 200. Two are aligned with the diversion openings 230 of the side rails 220 of the main conveyor belt 200, and one is aligned with its end along the main conveying direction. Material falls naturally into the corresponding diversion conveyor belt 300 below by gravity, preventing material from falling and scattering, and reducing coal loss. It should be noted that... Figures 1-4 In the diagram, the equipment structure of the main belt 200 and the three diversion conveyor belts 300 are simplified and are conventional conveyor belts. The layout, such as the angle between the two diversion conveyor belts 300 corresponding to the second diversion channel 310 and the third diversion channel 320 and the main belt 200, is not limited and can be adjusted according to the actual situation.

[0030] In some examples, the connecting part 430 laterally connects two symmetrically arranged guide plate parts 420. The connecting part 430 can be slidably connected to a preset slide rail on the base 100 via a slider. The assembly position of the connecting part 430 is higher than the bottom of the guide plate parts 420, that is, close to the upper end of the guide plate parts 420. A passage 410 for material passage is reserved below the connecting part 430 to ensure that the lower passage 410 is not obstructed. The size of the passage 410 is greater than or equal to the width of the main conveyor belt 200, which facilitates the passage of materials such as large pieces of coal, avoids material sticking and jamming, and ensures continuous conveying. The connecting part 430 is rigidly connected to the guide plate parts 420 to ensure that the tilt angle and symmetrical spacing of the two guide plate parts 420 are constant, and to avoid guide deviation during diversion. Specifically, when it is necessary to adjust the diversion path, the drive mechanism pushes the connecting part 430 to move along the sliding trajectory of the base 100. The connecting part 430 simultaneously drives the two guide plate parts 420 to move as a whole, ensuring that the movement of the two guide plate parts 420 is synchronized and without misalignment. The connecting part 430 drives the diverter 400 to move to the target position, so that the guide plate part 420 on one side blocks the first diverter channel 210 and the corresponding second diverter channel 310 or third diverter channel 320. After the material contacts the guide plate part 420, it is guided into the target diverter channel along the inclined surface.

[0031] In some examples, the diverter 400 is also provided with a baffle portion 440. The baffle portion 440, the connecting portion 430, and the guide plate portion 420 are integrally formed and can be detachably connected. One end of each baffle portion 440 is connected to the top of the corresponding guide plate portion 420. The guide plate portion 420 and the baffle portion 440 form a stable triangular structure. The position of the baffle portion 440 corresponds to the diversion port 230 of the side baffle 220 of the main conveyor belt 200. Its size is adapted to the diversion port 230 and can cover the area of ​​the diversion port 230. The diverter 400 as a whole is slidably connected to the base 100 through the connecting portion 430 to achieve synchronous movement. When the diverter 400 moves to the port 410 and aligns with the first diverter channel 210, the baffle part 440 fits against the diverter port 230 to achieve a blockage. When the diverter 400 moves to one side of the diverter channel, the baffle part 440 moves away from the diverter port 230 simultaneously with the diverter 400, without obstructing the material discharge. In the triangular structure, the inclined surface of the guide plate part 420 and the baffle part 440 form a support, which, together with the rigid constraint of the connecting part 430, ensures that the structure of the diverter 400 does not deform when subjected to force.

[0032] Specifically, the material travels straight along the first diversion channel 210. The drive connection 430 moves the diversion component 400, aligning the opening 410 with the first diversion channel 210. At this time, the two baffles 440 simultaneously adhere to the diversion openings 230 of the side guards 220 of the main conveyor belt 200, achieving a blockage on both sides. The material on the main conveyor belt 200 passes through the opening 410 and travels straight along the first diversion channel 210. Because the baffles 440 block the diversion openings 230 on both sides, no material leaks from the diversion openings 230 and eventually falls into the corresponding diversion conveyor belt 300. In traditional devices, the diversion openings 230 are open during straight-line travel, and bulk materials such as coal are prone to leaking from the diversion openings 230 due to vibration and accumulation, causing resource loss and site pollution. The baffles 440 block the diversion openings 230 during straight-line travel to prevent material leakage, adapting to the conveying needs of easily scattered materials such as fine coal and wet sticky coal.

[0033] In some examples, such as Figure 5 As shown, the linear drive assembly 500 includes a rotation drive member 530, which is fixed to the base 100. Its output end is connected to the crank arm 520 via a sprocket and chain 540. The crank arm 520 is rotatably mounted on the mounting platform 110 of the base 100 via a rotating shaft. The free end of the crank arm 520 is hinged to one end of the second connecting rod 510, and the other end of the second connecting rod 510 is hinged to the first connecting rod 450 fixed on the connecting part 430 of the diverter 400. The rotational motion of the rotation drive member 530 is synchronously transmitted to the crank arm 520 via the sprocket and chain 540. The circular motion of the crank arm 520 is converted into the linear motion of the first connecting rod 450 through the second connecting rod 510, thereby driving the diverter 400 to slide along the base 100.

[0034] Specifically, when the inlet 410 is aligned with the first diversion channel 210, the crank arm 520 is at the middle of its circumferential rotation. The diverter 400 remains stable under the traction of the connecting rod. The inlet 410 is aligned with the first diversion channel 210, and the baffle 440 blocks the two diversion ports 230. When the material is guided to the second diversion channel 310, the rotation drive 530 is activated. Its output end drives the crank arm 520 to rotate around the base 100 axially towards the main conveyor belt 200 via the sprocket and chain 540 until the crank arm 520 reaches the closest end of the circumference. The closest end refers to the distance between the crank arm 520 and the main conveyor belt 200. At this time, the crank arm 520 will be close to the main conveyor belt 200. The crank arm 520 pushes the first connecting rod 450 to move towards the third diversion channel 320 via the second connecting rod 510. After the diverter 400 moves, the single-sided guide plate 420 blocks the first diversion channel 210 and the third diversion channel 320. 0. When the baffle part 440 disengages from the diversion port 230, the material is guided into the second diversion channel 310. When the material is guided into the third diversion channel 320, the rotating drive 530 starts in reverse. The sprocket chain 540 drives the crank arm 520 to rotate away from the main conveyor belt 200. The crank arm 520 pulls the first link 450 to move towards the second diversion channel 310 through the second link 510. The flow element slides with the connecting part 430. The guide plate part 420 on the other side blocks the first diversion channel 210 and the second diversion channel 310. The baffle part 440 disengages from the diversion port 230, and the material is guided into the third diversion channel 320.

[0035] In this example, utilizing the fixed trajectory characteristic of the circular rotation of the crank arm 520, the three target positions of the diverter 400 are bound to the mechanical limit position and intermediate position of the crank arm 520. Limit switches are not required. The sprocket and chain transmission 540 ensures the synchronicity and stability of the crank arm 520's rotation, avoiding power transmission lag. The linkage mechanism, through the flexible rotation of the hinge point, achieves a smooth transition from circular motion to linear motion, ensuring that the diverter 400 moves without jamming. Furthermore, when the crank arm 520 reaches its mechanical limit position, its own structure restricts further rotation, preventing the diverter 400 from overtraveling. It should be noted that... Figures 1-4 In the middle, the second link 510 corresponds to Figure 5 The second link 510 is only shown as a structural illustration. In this example, the mounting platform 110 can be used to support... Figure 5 The rotating drive component 530 can be adjusted on the mounting platform 110 in practice to achieve the driving effect.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
