Description

Technical Field

[0001] The present invention relates to the technical field of coal yard stacking and reclaiming technology, and particularly to a coal yard stacking and reclaiming device with a windproof structure. Background Art

[0002] A coal yard refers to a place for storing coal, usually an auxiliary facility of a coal-fired power plant or a steel plant. With the continuous improvement of China's coal production capacity, the continuous strictness of national environmental protection policies, and the continuous enhancement of people's environmental protection awareness, the previously commonly used open-air coal storage method by coal production enterprises no longer meets the requirements. A fully enclosed coal storage yard that meets the actual needs of the enterprise must be adopted to ensure good economic, environmental, and social benefits for the enterprise. Since coal is mined and piled on open-air sites locally, it is necessary to transport the coal pile to a transport vehicle through a coal reclaiming machine, and then send the coal to the coal yard through the transport vehicle.

[0003] The working places of coal reclaiming machines are all in outdoor areas. Therefore, it is inevitable that there will be strong winds during the coal reclaiming process. Under the influence of strong winds, the coal being fed will be scattered and cannot fall concentratedly into the cargo box of the transport vehicle. Currently, most equipment, when encountering strong winds, backs the equipment against the direction of the strong wind to form a windbreak wall to reduce the impact of strong winds on coal feeding. However, in the case of variable wind directions, the coal being fed will still be blown apart, resulting in a low reclaiming efficiency of the coal pile. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a coal yard stacking and reclaiming device with a windproof structure, which solves the problem that the coal being fed is scattered under the influence of strong winds and cannot fall concentratedly into the cargo box of the transport vehicle.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A coal yard stacking and reclaiming device with a windproof structure includes a transport rack rotatably installed on a reclaiming machine. A fixed block is fixedly installed on the transport rack, and a transport plate is rotatably installed on the fixed block;

[0007] A windproof device for preventing strong winds from affecting the coal feeding is installed on the transport plate;

[0008] A cleaning device for preventing the material outlet from being blocked is installed on the windproof device;

[0009] An adjusting device is installed on the transport rack. By starting the adjusting device, the transport plate rotates. While the transport plate rotates, the windproof device rotates, and the cleaning device comes into contact with the bottom of the transport plate.

[0010] Preferably, the windproof device includes two groups of connecting blocks fixedly installed on the transport plate. A first rotating rod is rotatably installed on each group of connecting blocks. A rotating plate fixedly connected to the first rotating rod is rotatably installed on each group of connecting blocks. Two groups of second rotating rods are rotatably installed on the transport plate. A first helical gear is fixedly installed on each group of second rotating rods. Two second helical gears meshing with the first helical gears are fixedly installed on the fixed block.

[0011] Preferably, the windproof device further includes two groups of arc-shaped plates fixedly installed on the transport plate. A first sprocket is fixedly installed on each of the first rotating rod and the second rotating rod. A first chain is sleeved on the two first sprockets.

[0012] Preferably, the cleaning device includes two groups of grooves formed on the rotating plate. A connecting shaft is rotatably installed on each group of grooves. A fan is fixedly installed at one end of the connecting shaft. Two rotating columns are rotatably installed on the rotating plate.

[0013] Preferably, the cleaning device further includes a plurality of groups of springs uniformly installed on the rotating columns. A trapezoidal block is fixedly installed on the spring. A second sprocket is fixedly installed on each of the connecting shaft and the rotating column. A second chain is sleeved on the two second sprockets.

[0014] Preferably, the adjusting device includes two groups of adjusting motors fixedly installed on the transport frame. A worm is fixedly installed at the output end of each group of adjusting motors. Two worm wheels meshing with the worms are rotatably installed on the transport frame.

[0015] Preferably, the adjusting device further includes a fixed shaft fixedly installed on the worm wheel and rotatably connected to the transport frame. A gear is fixedly installed on the fixed shaft. An arc-shaped toothed plate meshing with the gear is installed on the arc-shaped plate.

[0016] Preferably, a driving motor is fixedly installed on the transport frame. A conveyor belt is slidably installed on the transport frame. Two plug-in frames are installed on the transport frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of the windproof device of the present invention, when the transport plate rotates, the rotating plate rotates to a state perpendicular to the transport plate, and the two rotating plates form a windproof channel, so that the transported coal can be concentrated and fall into the cargo box, avoiding the situation that the coal discharged under the influence of strong wind will be scattered and cannot be concentrated and fall into the cargo box of the transport vehicle.

[0019] 2. Through the provision of the cleaning device in the present invention, the rotation of the fan driven by the strong wind drives the rotation of the rotating column. As the rotating column rotates, the spring continuously deforms, and the trapezoidal block knocks on the bottom of the conveying plate, causing it to vibrate. This not only speeds up the blanking speed but also scatters large coal blocks, avoiding the situation where larger coal blocks formed by sticking may block the blanking port during blanking.

[0020] 3. Through the provision of the adjusting device in the present invention, starting the adjusting motor causes the worm to rotate, driving the fixed shaft connected to the worm gear to rotate. The rotation of the fixed shaft drives the gear to rotate. Under the action of the arc-shaped tooth plate, the rotation of the gear causes the conveying plate to rotate around the fixed block, which can guide the blanking of coal and facilitate the centralized falling of coal into the cargo box.

[0028] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Embodiment 1

[0030] Because the coal will be blown away by the strong wind and cannot fall into the cargo box of the transport vehicle, in order to solve this problem, refer to Figures 1-5 The present embodiment proposes a coal yard stacking and reclaiming device with a windproof structure, including a transport frame 1 rotatably mounted on a reclaimer, a fixed block 11 fixedly mounted on the transport frame 1, a transport plate 12 rotatably mounted on the fixed block 11, a drive motor 5 fixedly mounted on the transport frame 1, a conveyor belt 51 slidably mounted on the transport frame 1, two sets of plug-in frames 52 mounted on the transport frame 1, the plug-in frames 52 are used to connect a coal shoveling device, and an adjusting device 4 is mounted on the transport frame 1. By starting the adjusting device 4, the transport plate 12 is rotated, and the windproof device 2 is rotated while the transport plate 12 rotates, and the cleaning device 3 is brought into contact with the bottom of the transport plate 12. In the case of strong winds, the cleaning device 3 is driven to rotate and knock on the bottom of the transport plate 12, so that the transport plate 12 vibrates.

[0031] A windproof device 2 is installed on the transport plate 12 to prevent strong wind from affecting the unloading of coal. The windproof device 2 includes two groups of connecting blocks 21 fixedly installed on the transport plate 12, each group of connecting blocks 21 is rotatably installed with a No. 1 rotating rod 22, each group of connecting blocks 21 is rotatably installed with a rotating plate 23 fixedly connected to the No. 1 rotating rod 22, two groups of No. 2 rotating rods 24 are rotatably installed on the transport plate 12, each group of No. 2 rotating rods 24 is fixedly installed with a No. 1 bevel tooth 25, and two groups of No. 2 bevel teeth 26 meshing with the No. 1 bevel teeth 25 are fixedly installed on the fixed block 11. The windproof device 2 also includes two groups of arc plates 27 fixedly installed on the transport plate 12, and a No. 1 sprocket 28 is fixedly installed on the No. 1 rotating rod 22 and the No. 2 rotating rod 24. The two groups of No. 1 sprockets 28 A No. 1 chain 29 is sleeved on the upper part, and two groups of No. 1 sprockets 28 are connected through the No. 1 chain 29. Under the action of the adjusting device 4, the arc plate 27 drives the transport plate 12 to rotate. Under the action of the No. 2 bevel gear 26, the transport plate 12 rotates to make the No. 2 rotating rod 24 connected to the No. 1 bevel gear 25 rotate. Under the action of the No. 1 sprocket 28 and the No. 1 chain 29, the No. 2 rotating rod 24 rotates to drive the No. 1 rotating rod 22 to rotate. The No. 1 rotating rod 22 rotates to drive the rotating plate 23 to rotate, so that the rotating plate 23 rotates to a state perpendicular to the transport plate 12. The two groups of rotating plates 23 form a windproof channel, so that the transported coal can be concentrated into the cargo box, avoiding the situation that the unloaded coal will be blown away under the influence of strong wind and cannot fall into the cargo box of the transport vehicle in a concentrated manner.

[0032] Embodiment 2

[0033] Due to the relatively high humidity in the open-air area, it will cause the coal in the coal pile to stick together and form larger coal lumps, which may block the feeding port during feeding. To solve this problem, referring to Figures 1-5 , a cleaning device 3 for preventing the feeding port from being blocked is installed on the windproof device 2. The cleaning device 3 includes two groups of grooves 31 opened on the rotating plate 23. A connecting shaft 33 is rotatably installed on each group of grooves 31. One end of the connecting shaft 33 is fixedly installed with a fan 32. Two groups of rotating columns 34 are rotatably installed on the rotating plate 23. The cleaning device 3 further includes multiple groups of springs 35 evenly installed on the rotating columns 34. A trapezoidal block 36 is fixedly installed on the spring 35, which is convenient for knocking on the bottom of the conveying plate 12. Through the spring 35, the trapezoidal block 36 can easily knock on the bottom of the conveying plate 12. A second sprocket 37 is fixedly installed on both the connecting shaft 33 and the rotating column 34. A second chain 38 is sleeved on the two second sprockets 37. When the rotating plate 23 is unfolded, the strong wind blows the fan 32 to rotate, and the fan 32 drives the connecting shaft 33 to rotate. Under the action of the second sprocket 37 and the second chain 38, the rotation of the connecting shaft 33 drives the rotating column 34 to rotate. As the rotating column 34 rotates, the spring 35 continuously deforms and the trapezoidal block 36 knocks on the bottom of the conveying plate 12, causing it to vibrate. This not only speeds up the feeding speed but also scatters the large coal lumps, avoiding the situation where the larger coal lumps formed by sticking may block the feeding port during feeding.

[0034] The adjusting device 4 includes two groups of adjusting motors 41 fixedly installed on the conveying frame 1. The two groups of adjusting motors 41 are driven simultaneously by the same switch. The output end of each adjusting motor 41 is fixedly installed with a worm 42. Two groups of worm wheels 43 meshing with the worm 42 are rotatably installed on the conveying frame 1. The rotation of the conveying plate 12 can be limited through the transmission connection of the worm wheel 43 and the worm 42. The adjusting device 4 further includes a fixed shaft 44 fixedly installed on the worm wheel 43 and rotatably connected to the conveying frame 1. A gear 45 is fixedly installed on the fixed shaft 44. An arc-shaped toothed plate 46 meshing with the gear 45 is installed on the arc-shaped plate 27. Starting the adjusting motor 41 causes the worm 42 to rotate and drive the fixed shaft 44 connected to the worm wheel 43 to rotate. The rotation of the fixed shaft 44 drives the gear 45 to rotate. Under the action of the arc-shaped toothed plate 46, the rotation of the gear 45 causes the conveying plate 12 to rotate around the fixed block 11, which can guide the feeding of the coal and facilitate the coal to fall into the cargo box centrally.

[0035] Working principle: Start the regulating motor 41 to make the worm 42 rotate, which drives the fixed shaft 44 connected to the worm wheel 43 to rotate. The rotation of the fixed shaft 44 drives the gear 45 to rotate. Under the action of the arc-shaped toothed plate 46, the rotation of the gear 45 makes the conveying plate 12 rotate around the fixed block 11. The rotation of the conveying plate 12 makes the second rotating rod 24 connected to the first helical tooth 25 rotate. Under the action of the first sprocket 28 and the first chain 29, the rotation of the second rotating rod 24 drives the first rotating rod 22 to rotate. The rotation of the first rotating rod 22 drives the rotating plate 23 to rotate, so that the rotating plate 23 rotates to a state perpendicular to the conveying plate 12. The two rotating plates 23 form a wind shielding channel. When the rotating plates 23 are unfolded, the strong wind blows the fan 32 to rotate. The fan 32 drives the connecting shaft 33 to rotate. Under the action of the second sprocket 37 and the second chain 38, the rotation of the connecting shaft 33 drives the rotating column 34 to rotate. As the rotating column 34 rotates, the spring 35 is continuously deformed, and the trapezoidal block 36 knocks on the bottom of the conveying plate 12 to make it vibrate.
