Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining belt conveyor technology, and more specifically, to a coal stacking flow limiting device for belt conveyors. Background Technology
[0002] In coal mining projects, several belt conveyors are used to transport coal blocks. Two adjacent belt conveyors are connected by the head and tail of the conveyor to transfer coal blocks. However, coal blocks may accumulate at the transfer point at the head of the conveyor due to equipment or human factors. After the coal is piled up, the belt conveyor along the way may spill coal. Therefore, a coal pile-limiting device is usually installed at the head of the conveyor to prevent excessive coal accumulation at the transfer point.
[0003] Existing coal pile flow control devices mainly consist of support components and flow control plates. Typically, two flow control plates are installed on either side of the conveyor head via the support components. The two flow control plates and the conveyor together form a trough-shaped flow control channel, preventing coal spillage during transfer and subsequent transport. However, conveyor belts are located at different heights due to model variations or installation environments. Existing devices connect the support components and flow control plates via fasteners or welding. When applied to conveyor belts at different heights, the height of the flow control plates needs to be adjusted by disassembling and reassembling the fasteners or by modification to ensure proper flow control and the flow control channel is properly aligned with the conveyor, which is quite cumbersome. Utility Model Content
[0004] This invention provides a coal pile flow limiting device for belt conveyors, which can overcome some or all of the defects of the prior art.
[0005] According to the present invention, a coal piling and flow limiting device for a belt conveyor includes a device body, the device body including support members for being installed on both sides of the belt conveyor; flow limiting plates are provided at the support members, and the two flow limiting plates together with the belt conveyor form a trough-shaped channel for limiting the flow of coal blocks.
[0006] The support includes a vertically arranged upright, and a mounting seat that slides along the length of the upright at the flow-limiting plate; the mounting seat is arranged perpendicular to the upright and is provided with a positioning component; the positioning component includes a positioning block that slides along the length of the mounting seat, and the upright has multiple positioning ports spaced apart along its own length for the positioning blocks to extend into; the mounting seat is provided with a reset component that can push the positioning blocks into the positioning ports.
[0007] The positioning component of this invention allows the positioning block to engage with the corresponding positioning port after the height of the flow-limiting plate is adjusted by the sliding mounting seat, and the engagement is maintained by the reset component; thus, the height of the flow-limiting plate can be quickly adjusted to cooperate with belt conveyors of different heights to form a flow-limiting channel; this is more convenient than the prior art.
[0008] Preferably, the support member has two uprights connected by a crossbar; a vertically mounted plate is provided on one side of the uprights, and a positioning port is provided on the mounting plate; the two ends of the mounting base are respectively slidably engaged with the two uprights; a sliding cavity is provided on one side of the mounting base near the end; the cross-section of the sliding cavity is convex and a slider connected to the positioning block is slidably engaged; the reset member includes a spring placed in the sliding cavity; the spring is used to make the positioning block tend to extend into the positioning port.
[0009] In this invention, the spring allows the positioning block to maintain its tendency to extend into the positioning port, thus ensuring a proper fit with the positioning port and preventing the mounting base and flow restrictor from falling off. Furthermore, the position of the positioning block can be quickly adjusted to match positioning ports of different heights.
[0010] Preferably, the positioning block has an inclined guide surface on the side near the top of the upright; and a groove on the side of the positioning block away from the slider.
[0011] In this invention, by setting a guide surface, the positioning block can automatically disengage from the currently mating positioning port when the mounting base moves upward, so that when the mounting base is lifted to move the flow limiting plate upward, there is no need to adjust the position of the positioning block, that is, the height of the flow limiting plate is adjusted more quickly.
[0012] Preferably, a hinge plate is provided on one side of the flow restrictor, and the hinge plate is hinged to the upper end face of the mounting base; an adjusting component is provided at the mounting base; the adjusting component includes an adjusting rod that can pass through both sides of the mounting base and is threaded into the mounting base; one end of the adjusting rod is pressed against one side of the flow restrictor, and the other end is provided with a turntable.
[0013] In this invention, the adjustable component allows the adjusting rod to rotate and extend / retract at the mounting base when the turntable is rotated. When the adjusting rod extends / retracts, it presses against the flow-limiting plate and tilts the plate. This allows the tilt angle of the flow-limiting plate to be changed, enabling the channel size to be adjusted as needed. Furthermore, when the flow-limiting plate tilts, the height of its lower edge changes. If the positioning openings of the positioning components have excessive spacing, preventing the lower edge of the flow-limiting plate from fitting tightly against the conveyor belt and creating a gap, the adjusting component can precisely adjust the height of the lower edge of the flow-limiting plate to ensure a tight fit between the plate and the conveyor belt, preventing coal from leaking out through the gap.
[0014] Preferably, a stop plate is provided on one side of the flow restrictor. The stop plate is made of flexible material and is used to press the adjusting rod against it.
[0015] In this invention, the setting of the abutment plate allows the adjusting rod to be pressed tightly against the flexible abutment plate, thereby avoiding the rigid contact between the adjusting rod and the flow limiting plate, which would exacerbate damage.
[0016] Preferably, one of the support members is provided with a first connecting rod and a second connecting rod; another of the support members is provided with a first connecting rod and a second connecting rod; the first connecting rod is provided with a guide rod, and the first connecting rod is provided with a guide opening for the guide rod to extend into; the second connecting rod is rotatably fitted with a screw, and the second connecting rod is provided with a threaded opening for the screw to engage with the thread.
[0017] In this invention, the screw and guide rod are used to connect the two support components, so that the position of the two support components can be adjusted by rotating the screw, and the stability of the entire device can be ensured. Attached Figure Description

[0022] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.
[0023] Example 1
[0024] like Figure 1-4 As shown, this embodiment provides a coal flow limiting device for a belt conveyor, which includes a device body 100. The device body 100 includes support members 110 for being installed on both sides of the belt conveyor 101. Flow limiting plates 150 are provided at the support members 110, and the two flow limiting plates 150 and the belt conveyor 101 together form a trough-shaped channel 160 for limiting the flow of coal blocks.
[0025] The support member 110 includes a vertically arranged upright 211. The flow limiting plate 150 is provided with a mounting base 120 that slides along the length of the upright 211 and is slidably engaged with the upright 211. The mounting base 120 is arranged in a direction perpendicular to the upright 211 and is provided with a positioning component 130. The positioning component 130 includes a positioning block 332 that slides along the length of the mounting base 120. The upright 211 is provided with a plurality of positioning ports 3130 that are spaced apart along its own length and are used for the positioning blocks 332 to extend into. The mounting base 120 is provided with a reset member 333 that can push the positioning blocks 332 into the positioning ports 3130.
[0026] The positioning component 130 in this embodiment allows the positioning block 332 to engage with the corresponding positioning port 3130 after the sliding mounting base 120 adjusts the height of the flow-limiting plate 150, and maintains the engagement state through the reset component 333. This enables rapid adjustment of the height of the flow-limiting plate 150 to engage with belt conveyors 101 of different heights to form a flow-limiting channel 160, which is more convenient than existing technologies. Furthermore, when the flow-limiting plate 150 is tilted, the height of its lower edge changes. If the positioning port 3130 of the positioning component 130 has too large a gap, preventing the lower edge of the flow-limiting plate 150 from tightly fitting with the belt conveyor 101, the adjusting component 140 can precisely adjust the height of the flow-limiting plate 150. The height of the lower edge of 50 ensures a tight fit between the flow restrictor 150 and the belt conveyor 101, preventing coal from leaking out through gaps. Therefore, the adjusting component 140 can compensate for the poor accuracy of the positioning component 130 during adjustment. Finally, the guide rod 4700 and screw 4710 allow the two support components 110 to adjust their spacing and maintain the stability of the entire device. They can also adjust the spacing between the two flow restrictors 150, i.e., the width of the channel 160. In short, the entire device can quickly adjust the height of the two flow restrictors 150 to adapt to belt conveyors 101 of different heights, and can adjust the width of the channel 160 to adapt to belt conveyors 101 of different widths, ensuring that coal can pass through the channel 160 while achieving flow restriction.
[0027] In this embodiment, the support member 110 is provided with two uprights 211, which are connected by a crossbar 212. A vertically arranged mounting plate 213 is provided on one side of the uprights 211, and a positioning port 3130 is provided at the mounting plate 213. The two ends of the mounting base 120 are respectively slidably engaged with the two uprights 211. A sliding cavity 321 is provided on one side of the mounting base 120 near the end. The cross-section of the sliding cavity 321 is convex and a slider 331 connected to the positioning block 332 is slidably engaged. The reset member 333 includes a spring 3330 placed in the sliding cavity 321. The spring 3330 is used to make the positioning block 332 tend to extend into the positioning port 3130.
[0028] By setting the spring 3330 in this embodiment, the positioning block 332 can maintain the tendency to extend into the positioning port 3130, thereby cooperating with the positioning port 3130 so that the mounting base 120 and the flow limiting plate 150 will not fall off, and the position of the positioning block 332 can be quickly adjusted to cooperate with the positioning port 3130 at different heights; wherein the spring 3330 is a compression spring, and the reset member 333 can also be an elastic sheet with elastic potential energy, an air bag, etc.
[0029] In this embodiment, the positioning block 332 has an inclined guide surface 3320 on the side near the upper end of the upright 211; the positioning block 332 has a groove 3321 on the side away from the slider 331.
[0030] By using the guide surface 3320 in this embodiment, when the mounting base 120 moves upward, the guide surface 3320 causes the positioning block 332 to automatically disengage from the currently mating positioning port 3130. This eliminates the need to adjust the position of the positioning block 332 when the mounting base 120 is lifted to move the flow limiting plate 150 upward, making the adjustment of the height of the flow limiting plate 150 faster. The groove 3321 allows the operator to insert their fingers to manipulate the positioning block 332 and the slider 331. When adjusting the height of the flow limiting plate 150, the operator can place both hands on the lower end of the mounting base 120 and lift the mounting base 120 to directly raise the flow limiting plate 150. When it is necessary to lower the height of the flow limiting plate 150, the operator can use their thumb to grip the groove 3321 and the other four fingers to support the lower end of the mounting base 120. By using the thumb to manipulate the positioning block 332, the operator can compress the spring 3330. After lowering to the appropriate height, the operator can release the spring 3330 to return to its original position and engage the positioning block 332 with the corresponding positioning port 3130.
[0031] In this embodiment, a hinge plate 451 is provided on one side of the flow limiting plate 150, and is hinged to the upper end face of the mounting base 120 through the hinge plate 451; an adjusting member 140 is provided at the mounting base 120; the adjusting member 140 includes an adjusting rod 441 that can pass through both sides of the mounting base 120 and is threadedly engaged with the mounting base 120; one end of the adjusting rod 441 is pressed against one side of the flow limiting plate 150, and the other end is provided with a turntable 442.
[0032] The adjustment member 140 in this embodiment allows the adjustment rod 441 to rotate and extend / retract at the mounting base 120 when the turntable 442 is rotated. When the adjustment rod 441 extends / retracts, it presses against the flow-limiting plate 150 and tilts the flow-limiting plate 150. This allows the tilt angle of the flow-limiting plate 150 to be changed via the adjustment member 140, enabling the size of the channel 160 to be adjusted according to requirements. Furthermore, when the flow-limiting plate 150 tilts, the height of its lower edge changes. If the positioning openings 3130 of the positioning component 130 have too large a gap, preventing the lower edge of the flow-limiting plate 150 from tightly fitting with the belt conveyor 101, this can be addressed by adjusting the adjustment member 140. The component 140 precisely adjusts the height of the lower edge of the flow restrictor 150 to ensure a tight fit between the flow restrictor 150 and the belt conveyor 101, preventing coal from leaking out through gaps. The upper end face of the flow restrictor 150 has an opening for the upright 211 to extend into, allowing the length of the flow restrictor 150 to be greater than the distance between two uprights 211. Flow restrictors 150 of different lengths can be designed, and when the flow restrictor 150 is tilted, the distance between it and the upright 211 can be reduced, thereby reducing the space occupied by the entire support component 110 and the flow restrictor 150. Furthermore, when multiple sets of devices are installed, the flow restrictors 150 of each set can be seamlessly connected to form a longer and seamless flow restricting channel 160.
[0033] In this embodiment, a stop plate 443 is provided on one side of the flow limiting plate 150. The stop plate 443 is made of flexible material and is used for the adjusting rod 441 to be pressed against it.
[0034] By setting the abutment plate 443 in this embodiment, the adjusting rod 441 can be pressed against the flexible abutment plate 443, thereby avoiding the rigid contact between the adjusting rod 441 and the flow limiting plate 150, which will aggravate damage. The abutment plate 443 can be a non-slip rubber plate.
[0035] In this embodiment, one support member 110 is provided with a first connecting rod 470 and a second connecting rod 471; another support member 110 is provided with a first docking rod 480 and a second docking rod 481; the first connecting rod 470 is provided with a guide rod 4700, and the first docking rod 480 is provided with a guide opening 4800 for the guide rod 4700 to extend into; the second connecting rod 471 is rotatably fitted with a screw 4710, and the second docking rod 481 is provided with a threaded opening 4810 for the screw 4710 to be threaded into.
[0036] The screw 4710 and guide rod 4700 in this embodiment enable the connection between the two support members 110, allowing the position of the two support members 110 to be adjusted by rotating the screw 4710, thus ensuring the stability of the entire device. The first connecting rod 470 and the second connecting rod 471 are respectively vertically connected to the two uprights 211 of one support member 110, and the first docking rod 480 and the second docking rod 481 are similarly connected to the other support member 110. The first connecting rod 470 and the first docking rod 480 are coaxially arranged, and the second connecting rod 471 and the second docking rod 481 are coaxially arranged.
[0037] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
[0038] The present invention and its embodiments have been described above illustratively.
