[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] A bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine for continuous conveying that can both stack and reclaim materials in a large bulk cargo yard. The head material guiding trough is located at the forefront of the conveyor belt of the bucket wheel stacker-reclaimer and can be lifted and lowered. During the reclaiming operation, the material guiding trough is lowered, and the material is conveyed backward through the material guiding trough and the conveyor belt; during the stacking operation, the head material guiding trough is in the lifted state, and the material is sent to the yard through the conveyor belt. Currently, the dust-proof rubber of the head material guiding trough is installed close to the bottom lining of the material guiding trough. Since the distance between the dust-proof rubber and the bottom lining is too close, it is easy to get stuck with coal lumps, and after getting stuck with coal lumps, the dust-proof rubber is very easy to be damaged.

[0032] The present invention provides a material guiding trough device and a bucket wheel stacker-reclaimer, which set a dust-proof plate outside the material guiding trough and adjust the distance between the dust-proof plate and the bottom lining through an adjusting assembly, avoiding the dust-proof plate from getting stuck with materials due to the too-close distance between the dust-proof plate and the bottom lining and then causing damage to the dust-proof plate, and improving the service life of the dust-proof plate.

[0033] Figure 1 It is a schematic structural diagram of a material guiding trough device from one perspective in an embodiment of the present invention; Figure 2 It is a schematic structural diagram of a material guiding trough device from another perspective in an embodiment of the present invention. As Figure 1-2As shown in the figure, an embodiment of the present application provides a material guiding trough device 1000 for a bucket wheel stacker-reclaimer. The material guiding trough device 1000 includes: a material guiding trough body 100, an adjusting assembly 200, and a dust-proof plate 300. The material guiding trough body 100 includes a frame 110 and a bottom lining plate 120, and the bottom lining plate 120 is arranged at the bottom of the frame 110. The adjusting assembly 200 is installed on the outer side of the frame 110. The adjusting assembly 200 is connected to the dust-proof plate 300 and is used to move the dust-proof plate 300 along the first direction X away from or close to the bottom lining plate 120.

[0034] The bottom lining plate 120 arranged at the bottom of the frame 110 of the material guiding trough body 100 can play a role in guiding the material and ensure that the material is transported along a predetermined path.

[0035] It should be noted that the adjusting assembly 200 is installed on the outer side of the frame 110. In this embodiment, it means that the adjusting assembly 200 is installed on the outer side of the frame 110 along the length direction. The first direction X intersects with the length direction of the frame 110. Preferably, the first direction X is perpendicular to the length direction of the frame 110. Of course, it can be understood that since the bottom lining plate 120 is installed at the bottom on both sides of the frame 110 along the length direction, the corresponding adjusting assemblies 200 and dust-proof plates 300 are arranged in one-to-one correspondence on the outer side walls of the frame 110 along the length direction.

[0036] According to the material guiding trough device 1000 of the embodiment of the present application, the dust-proof plate 300 can be adjusted through the adjusting assembly 200, so that the dust-proof plate 300 can move away from or close to the bottom lining plate 120, and further a proper distance is maintained between the dust-proof plate 300 and the bottom lining plate 120, avoiding damage to the dust-proof plate 300 caused by material jamming due to the too close distance between the dust-proof plate 300 and the bottom lining plate 120, and improving the service life of the dust-proof plate 300.

[0037] As Figure 2 shown, in some embodiments, the material guiding trough device 1000 further includes a conveyor belt 500. The material guiding trough body 100 is arranged above the conveyor belt 500, and the bottom of the dust-proof plate 300 abuts against the conveyor belt 500.

[0038] In this embodiment, the material guiding trough body 100 is arranged above the conveyor belt 500, and the material of the material guiding trough body 100 is transported through the material guiding trough body 100 and the conveyor belt 500. Since the bottom of the dust-proof plate 300 abuts against the conveyor belt 500, the material will not spill outside the conveyor belt 500 from the dust-proof plate 300, ensuring the maximization of the dust-proof effect, and also helping to reduce the loss of the material during the transportation process, improving the overall working efficiency and economic benefits.

[0039] In some alternative embodiments, the walls on both sides of the conveyor belt 500 in the length direction form an angle with the bottom surface. When the distance requirement from the bottom lining 120 is met, the outer side surface of the bottom of the dust-proof plate 300 can be adjusted to be attached to the conveyor belt 500 through the adjusting assembly 200, so that the dust-proof rubber is not easily worn and the conveyor belt 500 is not scratched.

[0040] As Figure 3 shown and referring to Figure 1-2 , in some embodiments, the adjusting assembly 200 includes at least two sliding assemblies 210. The sliding assembly 210 includes a sliding rail 211 and a slider 212 that cooperate with each other. The sliding rail 211 is connected to the outer side wall of the frame 110 and extends along the first direction X, and the dust-proof plate 300 is connected to the slider 212.

[0041] In this embodiment, the sliding assemblies 210 are arranged at intervals along the length direction of the frame 110. The slider 212 drives the dust-proof plate 300 to slide relative to the sliding rail 211, so that the dust-proof plate 300 moves away from or approaches the bottom lining 120 along the first direction X to adjust the distance between the dust-proof plate 300 and the bottom lining 120.

[0042] In some other alternative embodiments, the sliding assembly 210 can also be a sliding rail 211 and a sliding sleeve that cooperate with each other. The sliding rail 211 is arranged on the outer side wall of the frame 110 and extends along the first direction X, and the dust-proof plate 300 is connected to the sliding sleeve.

[0043] Furthermore, a plurality of balls are arranged between the sliding sleeve and the sliding rail 211 to reduce the friction and wear between the sliding sleeve and the sliding rail 211 and extend the service life of the sliding sleeve and the sliding rail 211. At the same time, the rolling of the balls makes the movement of the sliding sleeve on the sliding rail 211 more stable.

[0044] As Figure 3 shown and referring to Figure 1-2 , in some embodiments, the adjusting assembly 200 further includes a driving assembly 220 corresponding to the sliding assembly 210 one by one. The driving assembly 220 is connected to the slider 212 and is used to drive the slider 212 to slide along the sliding rail 211.

[0045] In this embodiment, the driving assembly 220 can drive the slider 212 to slide along the sliding rail 211, realizing the automatic operation of the slider 212 and reducing the labor intensity of workers.

[0046] As Figure 3 shown and referring to Figure 1-2 , in some embodiments, the driving assembly 220 includes a lead screw 221 and a nut 222 that cooperate with each other. The lead screw 221 extends parallel to the sliding rail 211. One end of the lead screw 221 is rotatably connected to the outer side wall of the frame 110, and the nut 222 is fixedly connected to the slider 212.

[0047] In this embodiment, by rotating the lead screw 221 relative to the nut 222, the nut 222 drives the slider 212 to slide along the slide rail 211, so that the dust-proof plate 300 connected to the slider 212 moves along the first direction X. The cooperation between the lead screw 221 and the nut 222 has high precision, and can realize the precise sliding of the slider 212 along the slide rail 211. The structures of the lead screw 221 and the nut 222 are relatively simple, and are easy to maintain and replace. At the same time, when the lead screw 221 stops rotating, due to the action of friction, the nut 222 will stop moving on the lead screw 221 to form self-locking, so that the relative position between the slider 212 and the slide rail 211 is locked, and the distance between the dust-proof plate 300 and the bottom lining plate 120 remains stable.

[0048] In some other alternative embodiments, the drive assembly 220 may also be a hydraulic telescopic cylinder or a telescopic electric cylinder. The telescopic rod of the hydraulic telescopic cylinder or the electric telescopic cylinder is connected to the slider 212 and is used to drive the slider 212 to slide along the slide rail 211.

[0049] As Figure 3 shown, and referring to Figure 1 , in some embodiments, the drive assembly 220 further includes a drive motor 230. The drive motor 230 is connected to the lead screw 221 and is used to drive the lead screw 221 to rotate relative to the nut 222.

[0050] In this embodiment, the drive motor 230 drives the lead screw 221 to rotate, so that while the lead screw 221 rotates relative to the nut 222, the nut 222 moves relative to the lead screw 221, so that the nut 222 drives the slider 212 to move relative to the slide rail 211, improving the work efficiency and the automation level.

[0051] In some alternative embodiments, a scale K1 is further provided on the slide rail 211, so that when the slider 212 moves relative to the slide rail 211, the distance between the dust-proof plate 300 and the bottom lining plate 120 can be quickly and accurately set with reference to the scale K1, avoiding repeated operations and improving the work efficiency and accuracy.

[0052] In some alternative embodiments, a first distance D1 is set between the bottom lining plate 120 and the dust-proof plate 300 in the first direction X. The first distance D1 is not less than 15 CM to prevent the material from being stuck due to the too close distance between the bottom lining plate 120 and the dust-proof plate 300, and to prevent the dust-proof plate 300 and the conveyor belt 500 from being damaged.

[0053] As Figure 4 shown, and referring to Figure 1-2 , in some embodiments, the material guiding groove device 1000 further includes a bracket 400. The dust-proof plate 300 is connected to the adjusting assembly 200 through the bracket 400.

[0054] In this embodiment, the dust-proof plate 300 is connected to the adjustment assembly 200 through the bracket 400. The adjustment assembly 200 moves along the first direction X through the adjustment bracket 400, indirectly driving the dust-proof plate 300 to move along the first direction X. The dust-proof plate 300 is installed on the bracket 400, and then the dust-proof plate 300 is installed on the outside of the frame 110 of the material guiding groove body 100 through the bracket 400, making the installation of the dust-proof plate 300 more convenient.

[0055] As Figure 4 shown, and referring to Figure 2 . In some embodiments, the bracket 400 includes a support rod 410 and a plurality of connecting members 420. Both ends of the support rod 410 are respectively connected to the adjustment assembly 200. One end of each connecting member 420 is connected to the support rod 410, and the other end of each connecting member 420 is connected to the dust-proof plate 300; the plurality of connecting members 420 are sequentially arranged at intervals along the length direction of the support rod 410.

[0056] It should be noted that in this embodiment, the two ends of the support rod 410 are respectively connected to the adjustment assembly 200, which means that the two ends of the support rod 410 are connected to the slider 212 in the sliding assembly 210. The slider 212 moves along the slide rail 211, so that the slider 212 drives the support rod 410 to move along the slide rail 211, and further makes the dust-proof plate 300 move along the first direction X.

[0057] In this embodiment, the dust-proof plate 300 is connected to the support rod 410 by connecting to a plurality of connecting members 420. The adjustment assembly 200 moves the support rod 410 along the first direction X, so that the dust-proof plate 300 moves along the first direction X. Specifically, by adjusting the slider 212 connected to the support rod 410 to move along the slide rail 211, the dust-proof plate 300 moves along the first direction X to adjust the distance between the dust-proof plate 300 and the bottom lining plate 120 at the bottom of the frame 110, avoiding scratching the conveyor belt 500 due to the distance between the dust-proof plate 300 and the bottom lining plate 120 being too close and jamming materials, and at the same time preventing the dust-proof plate 300 from being damaged, improving the service life of the dust-proof plate 300 and the conveyor belt 500.

[0058] In some alternative embodiments, both ends of the support rod 410 are respectively rotatably connected to the slider 212. By rotating the support rod 410 relative to the slider 212, the distance between the dust-proof plate 300 and the bottom lining plate 120 is adjusted, and the side surface of the dust-proof plate 300 can be made to fit the conveyor belt 500, avoiding materials from spilling through the gap between the dust-proof plate 300 and the conveyor belt 500.

[0059] As Figure 4As shown, in some embodiments, each connecting member 420 is provided with a strip-shaped hole L extending in the second direction Y. The dust-proof plate 300 is provided with a plurality of mounting holes at intervals along its length direction. The mounting holes correspond to the strip-shaped holes L one by one. The strip-shaped holes L and the mounting holes are fixedly connected by fasteners. The first direction X intersects with the second direction Y.

[0060] In this embodiment, the alignment position of the mounting hole and the strip-shaped hole L can be adjusted to move the dust-proof plate 300 in the second direction, so that the adjusting member can not only adjust the dust-proof plate 300 to move along the first direction X, but also adjust the dust-proof plate 300 to move along the second direction Y.

[0061] Furthermore, the strip-shaped hole L and the mounting hole are fixedly connected by fasteners. The fasteners can be matching screws and nuts or rivets, etc.

[0062] In some other alternative embodiments, the connecting member 420 can also be provided with a buckle or a clamping device, and is fixedly connected to the dust-proof plate 300 through the buckle or the clamping device.

[0063] In some embodiments, a plurality of limiting grooves are sequentially arranged at intervals along the length direction of the strip-shaped hole L. The limiting grooves are hemispherical.

[0064] In this embodiment, a plurality of limiting grooves are sequentially arranged at intervals along the length direction of the strip-shaped hole L. When the dust-proof plate is installed on the bracket, by aligning the mounting hole on the dust-proof plate 300 with the limiting groove at the same position of the corresponding strip-shaped hole L, when the dust-proof plate 300 moves along the second direction Y, it can move the same distance, avoiding different moving distances of the dust-proof plate 300 when moving in the second direction Y, and avoiding the inclination of the dust-proof plate installed on the bracket.

[0065] The embodiment of the present application also provides a bucket wheel stacker-reclaimer. The bucket wheel stacker-reclaimer includes the material guiding groove device 1000 in any of the above embodiments, and thus has all the technical effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0066] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and the components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
