Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, and more specifically, to a coal processing conveyor. Background Technology

[0002] Coal, as an important fossil energy source, is mainly formed from ancient plants under specific geological conditions. It is a key component of the global energy structure. It is not only the main fuel for power generation, but also widely used in many industrial fields such as steel smelting and chemical raw material manufacturing. In the coal processing process, conveyors are needed to transport coal to designated locations to facilitate subsequent processing.

[0003] For example, Chinese Patent Publication No. CN202323090004.7 discloses a coal conveying device, including a conveyor body, a scraper, a spray assembly, and a receiving frame. The conveyor body has a conveyor belt for conveying coal. The scraper, located at the lower end of the conveyor body, scrapes off coal adhering to the conveyor belt. The spray assembly sprays the cleaned conveyor belt with water. The spray assembly includes a spray pipe and multiple spray heads connected to the spray pipe. A water pipe is located below the spray pipe, and a water pump is installed on the water pipe. The receiving frame includes a vertical section and two inclined connecting sections connected to the vertical section. This invention improves the cleaning effect of the conveyor belt and extends its service life by having the conveyor belt pass through the scraper, the spray assembly, and the drying assembly in sequence.

[0004] However, in the above-mentioned technical solutions, traditional coal conveyors usually adopt a fixed belt conveyor structure, and their unloading point is in a single location, which makes it difficult to meet the process requirements of flexible batching of multiple processes and nodes in modern coal processing. Especially in scenarios such as coal washing plants and coal blending centers, coal often needs to be distributed to multiple designated silos or processing links. Existing technologies often require multiple parallel conveyor lines or frequent start-stop transfer equipment to achieve this, resulting in a large system footprint, high energy consumption, and low collaborative efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a coal processing conveyor that can effectively solve the problem that traditional coal conveyors in the background art typically adopt a fixed belt conveyor structure with a single unloading point, making it difficult to meet the process requirements of flexible batching for multiple processes and nodes in modern coal processing. Especially in scenarios such as coal washing plants and coal blending centers, coal often needs to be distributed to multiple designated silos or processing stages. Existing technologies often require multiple parallel conveyor lines or frequent start-stop transfer equipment, resulting in a large system footprint, high energy consumption, and low collaborative efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coal processing conveyor, including a conveyor belt, with support columns and several threaded holes provided on both outer walls of the conveyor belt, several bolts threaded on the support columns, a crossbeam provided between two support columns, a sliding groove provided on the side of the support column near the crossbeam, the two ends of the crossbeam sliding in the sliding groove, an installation block fixedly provided on the lower outer wall of the crossbeam, an adjustment component provided on the installation block, two unloading plates provided between the conveyor belt and the installation block, and a certain gap left between the conveyor belt and the unloading plates.

[0007] Preferably, the support column is fixedly connected to the conveyor belt by bolts and threaded holes, and the crossbeam is located directly above the conveyor belt.

[0008] Preferably, the support column is L-shaped.

[0009] Preferably, the adjustment assembly has a first rotating column rotatably mounted on the mounting block, a worm gear and a first gear mounted on the first rotating column, a worm engaged on one side of the worm gear, a transmission column fixedly mounted on one end of the worm, a knob fixedly mounted on the end of the transmission column away from the worm, a second gear engaged on one side of the first gear, and a second rotating column mounted on the second gear.

[0010] Preferably, one end of the first rotating column and the second rotating column rotatably penetrates the mounting block, the worm gear is rotatably mounted on the mounting block, and the end of the transmission column away from the worm gear rotatably penetrates the mounting block.

[0011] Preferably, the first rotating column and the second rotating column are fixedly connected to different unloading plates at one end of the rotating through mounting block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When using this utility model, first install the support column to the position where the conveyor belt needs to be unloaded by bolts and threaded holes. Then turn the knob to make the ends of the two unloading plates that are far apart gradually move closer or further apart according to the width of the conveyor belt, so that the ends of the two unloading plates that are far apart are on the same longitudinal axis as the outer wall surfaces on both sides of the conveyor belt. Then pour the coal onto the conveyor belt. When the coal moves to the unloading plate, the coal that is parallel to the unloading plate will be blocked by the unloading plate, while the coal that is lower than the unloading plate will be transported to the designated position by the conveyor belt. Subsequently, with the compression of the subsequent coal, the coal blocked by the unloading plate moves along the trajectory of the unloading plate to both sides of the conveyor belt, completing the diversion unloading. Multiple unloading points can be achieved on one conveyor belt, improving the flexibility and utilization of the conveyor line and adapting to the needs of different unloading positions.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, a coal processing conveyor includes a conveyor belt 1. Support columns 2 and several threaded holes 3 are provided on both outer walls of the conveyor belt 1. Several bolts 4 are threaded onto the support columns 2. A crossbeam 5 is provided between two support columns 2. A groove 6 is provided on the side of the support column 2 closest to the crossbeam 5. The ends of the crossbeam 5 slide in the groove 6. An installation block 7 is fixedly provided on the outer wall below the crossbeam 5. An adjustment component 8 is provided on the installation block 7. Two unloading plates 9 are provided between the conveyor belt 1 and the installation block 7, with a certain gap between the conveyor belt 1 and the unloading plates 9.

[0020] like Figure 3 As shown, in another embodiment of the present invention, the adjusting component 8 is rotatably provided with a first rotating column 801 on the mounting block 7. The first rotating column 801 is provided with a worm gear 802 and a first gear 803. A worm 804 is meshed on one side of the worm gear 802. A transmission column 805 is fixedly provided at one end of the worm 804. A knob 806 is fixedly provided at the end of the transmission column 805 away from the worm 804. A second gear 807 is meshed on one side of the first gear 803. A second rotating column 808 is provided on the second gear 807.

[0021] When it is necessary to rotate the two unloading plates 9, the transmission column 805 is first rotated by the knob 806. The transmission column 805 rotates the worm 804, which drives the worm wheel 802 to rotate. The worm wheel 802 drives the first rotating column 801 to rotate. At the same time, the first rotating column 801 drives the second gear 807 to rotate through the first gear 803. The second gear 807 drives the second rotating column 808 to rotate. The first rotating column 801 and the second rotating column 808 drive the different unloading plates 9 to rotate, so that the ends of the two unloading plates 9 that are far apart gradually move closer or further apart, thereby adapting to the different widths of the conveyor belt 1. The unidirectional transmission of the worm wheel 802 and the worm 804 limits the two unloading plates 9 to a certain extent, preventing the unloading plates 9 from rotating easily.

[0022] The working principle of this type of coal processing conveyor:

[0023] In use, firstly, the support column 2 is installed to the position where the conveyor belt 1 needs to unload material using bolts 4 and threaded holes 3. Then, the knob 806 is turned, which causes the worm gear 804 to rotate via the transmission column 805. The worm gear 804 drives the first rotating column 801 to rotate via the worm wheel 802. Simultaneously, the first rotating column 801 drives the second gear 807 to rotate via the first gear 803. The second gear 807 drives the second rotating column 808 to rotate. The first rotating column 801 and the second rotating column 808 respectively drive different unloading plates 9 to rotate. According to the width of the conveyor belt 1, the ends of the two unloading plates 9 on opposite sides are gradually moved apart. The two unloading plates 9 gradually move closer or further apart, so that the ends of the two unloading plates 9 that are far apart are aligned with the outer walls of both sides of the conveyor belt 1 on the same longitudinal axis. Then, the coal is poured onto the conveyor belt 1. When the coal moves to the unloading plate 9, the coal parallel to the unloading plate 9 will be blocked by the unloading plate 9, while the coal lower than the unloading plate 9 will be transported to the designated position by the conveyor belt 1. Subsequently, with the compression of the subsequent coal, the coal blocked by the unloading plate 9 moves along the trajectory of the unloading plate 9 to both sides of the conveyor belt 1, completing the diversion unloading. Multiple unloading points can be achieved on one conveyor belt 1, improving the flexibility and utilization of the conveyor line and adapting to the needs of different unloading positions.

[0024] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
