TECHNICAL FIELD

[0001] The present application relates to the technical field of coal yard stacking and reclaiming, in particular to a coal yard stacking and reclaiming device with a windproof structure. BACKGROUND

[0002] A coal yard refers to a place for stacking coal, and is usually an auxiliary facility of a coal-fired power plant or a steel plant. With the continuous improvement of coal production capacity in China, the continuous tightening of national environmental protection policies, and the continuous enhancement of people's environmental protection awareness, the open-air coal storage method previously commonly used by coal production enterprises no longer meets the requirements, and 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 of the enterprise. Since coal is stacked in an open-air place after mining, the coal stack needs to be transported to a transport vehicle by a coal reclaiming machine, and then the coal is transported to the coal yard by the transport vehicle.

[0003] The working place of the coal reclaiming machine is in an outdoor area, so it is inevitable that there will be strong winds during the process of reclaiming coal. Under the influence of strong winds, the coal being unloaded will be blown away and cannot be concentrated into the cargo box of the transport vehicle. At present, most equipment backs up against the direction of the strong wind to form a windbreak to reduce the impact of strong winds on the unloading of coal. However, in the case of changing wind directions, the coal being unloaded will still be blown away, resulting in low efficiency of reclaiming coal from the coal stack. SUMMARY

[0004] To overcome the shortcomings of the prior art, the present application provides a coal yard stacking and reclaiming device with a windproof structure, which solves the problem that the coal being unloaded will be blown away and cannot be concentrated into the cargo box of the transport vehicle under the influence of strong winds.

[0031] The transport plate 12 is provided with a windproof device 2 for preventing the coal under the influence of strong wind from being blown away, the windproof device 2 comprising two groups of connecting blocks 21 fixedly installed on the transport plate 12, a first rotating rod 22 rotatably installed on each connecting block 21, a rotating plate 23 fixedly connected with the first rotating rod 22 and rotatably installed on each connecting block 21, two groups of second rotating rods 24 rotatably installed on the transport plate 12, a first bevel gear 25 fixedly installed on each second rotating rod 24, two groups of second bevel gears 26 fixedly installed on the fixed block 11 and meshing with the first bevel gears 25, and two groups of arc-shaped plates 27 fixedly installed on the transport plate 12, a first sprocket 28 fixedly installed on each first rotating rod 22 and second rotating rod 24, a first chain 29 sleeved on the two groups of first sprockets 28, and the two groups of first sprockets 28 being transmissionally connected through the first chain 29, the arc-shaped plates 27 driving the transport plate 12 to rotate under the action of the adjusting device 4, the transport plate 12 rotating to drive the second rotating rod 24 connected with the first bevel gear 25 to rotate under the action of the second bevel gear 26, the second rotating rod 24 rotating to drive the first rotating rod 22 to rotate under the action of the first sprocket 28 and the first chain 29, the first rotating rod 22 rotating to drive the rotating plate 23 to rotate to a state perpendicular to the transport plate 12, and the two groups of rotating plates 23 forming a wind-blocking channel, so that the transported coal can be concentrated into the truck box, avoiding the situation that the coal under the influence of strong wind will be blown away so that it cannot be concentrated into the truck box.

[0032] Embodiment two

[0033] Due to the high humidity of the open place, the coal of the coal pile will stick together and form large coal blocks, which may cause the blockage of the discharge port during discharging. In order to solve this problem, referring to Figures 1-5 , the cleaning device 3 for preventing the blockage of the discharge port is installed on the windproof device 2. The cleaning device 3 includes two groups of grooves 31 opened on the rotating plate 23, and a connecting shaft 33 rotatably installed on each group of grooves 31. One end of the connecting shaft 33 is fixedly installed with a fan 32. The rotating plate 23 is rotatably installed with two groups of rotating columns 34. The cleaning device 3 further includes a plurality of springs 35 uniformly installed on the rotating columns 34, and a trapezoidal block 36 fixedly installed on the spring 35, which facilitates knocking the bottom of the transportation plate 12. The trapezoidal block 36 can knock the bottom of the transportation plate 12 through the spring 35. The connecting shaft 33 and the rotating column 34 are both fixedly installed with a second sprocket 37. Two groups of second sprockets 37 are sleeved with a second chain 38. When the rotating plate 23 is unfolded, the fan 32 is rotated by the strong wind. The fan 32 drives the connecting shaft 33 to rotate. Under the action of the second sprocket 37 and the second chain 38, the connecting shaft 33 drives the rotating column 34 to rotate. The rotation of the rotating column 34 causes the spring 35 to continuously deform and the trapezoidal block 36 to knock the bottom of the transportation plate 12, causing it to vibrate. This not only speeds up the discharging speed, but also scatters large coal blocks, avoiding the blockage of the discharge port caused by the large coal blocks formed by sticking.

The two groups of adjusting motors 41 are driven by the same switch at the same time. The output end of each adjusting motor 41 is fixedly installed with a worm 42. The transportation frame 1 is rotatably installed with two groups of worm gears 43 meshing with the worms 42. The transmission connection of the worm gears 43 and the worms 42 can limit the rotation of the transportation plate 12. The adjusting device 4 further includes a fixed shaft 44 fixedly installed on the worm gear 43 and rotatably connected with the transportation frame 1. The fixed shaft 44 is fixedly installed with a gear 45. The arc-shaped plate 27 is installed with an arc-shaped toothed plate 46 meshing with the gear 45. The rotation of the worm 42 drives the fixed shaft 44 to rotate by starting the adjusting motor 41. The rotation of the fixed shaft 44 drives the gear 45 to rotate. The rotation of the gear 45 causes the transportation plate 12 to rotate around the fixed block 11 under the action of the arc-shaped toothed plate 46. This can guide the discharging of coal and facilitate the concentration of coal falling into the cargo box.
