By setting the support component 27, when the baffle 26 moves, the rollers 274 at both ends of the baffle 26 roll on the strip plate 271, and the rollers 274 rotate on the baffle 26 through the rotating shaft 273. The support assembly 27 is provided to support the movement of the baffle 26, so that the movement of the baffle 26 is more stable. When the coal is unloaded, the motor 31 is turned on, and the motor 31 drives the rotating rod 32 to rotate. The rotating rod 32 drives the rotating rod 33 to rotate through the gear 1 35 and the gear 2 36. The rotating rod 1 32 and the rotating rod 2 33 rotate to stir the coal in the storage space through a plurality of stirring rods 34. The stirring assembly 3 is provided to stir the coal in the coal bunker body 1 to avoid coal blockage and failure to unload. The lubricating assembly 37 is provided to add lubricating oil to the oil tank 371, and one end of the rope body 373 inside the folded tube 372 absorbs the lubricating oil in the oil tank 371, and the other end of the rope body 373 drips the lubricating oil onto the gear 1 35, so as to achieve the purpose of unloading the gear 1. The lubrication effect of gear 35 and gear 2 36 is achieved. The oil receiving box 374 can receive excess lubricating oil. The lubrication component 37 can be set to lubricate gear 1 35 and gear 2 36. Dust is generated when coal is added to the coal bunker body 1 through the feed port 6. The fan 42 is turned on. The fan 42 forms a negative pressure in the dust inlet hopper 45 at one end of the fixed pipe 43 through the rectangular tube 44, and the dust is sucked into the dust reduction box 41. The dust is filtered through the sand and gravel layer 46 and the activated carbon layer 47 and then discharged from the dust reduction box 41. When dust is generated by adding coal to the coal bunker body 1 by setting the dust reduction component 4, dust reduction treatment can be performed to reduce air pollution. By setting the installation component 48, when the sand and gravel layer 46 and the activated carbon layer 47 are installed, the sand and gravel layer 46 and the activated carbon layer 47 are installed. The mounting opening 482 is inserted into the card slot 485 of the dust suppression box 41, and then the mounting plate 481 is placed into the mounting opening 482, and the fixing bolts 483 are screwed into the fixing holes 484 to fix the mounting plate 481. By setting the mounting assembly 48, it is convenient to disassemble and replace the activated carbon layer 47 and the sand and gravel layer 46. When the device needs to be moved, the motor 2 53 is turned on, and the motor 2 53 drives the double-axis screw 54 to rotate. The rotation of the double-axis screw 54 drives the two slides 55 to approach each other. The two slides 55 approach each other and push the moving plate 56 downward through the rotating plate 58. The moving plate 56 moves downward to move the universal wheel 57 at the lower end out of the bottom box 51, thereby lifting the device. The device can be moved through the universal wheel 57. By setting the moving assembly 5, it is convenient for the device to be moved to different positions for use.By setting the fixing assembly 59, the device is moved to a suitable position and the electric push rod 2 592 is turned on. The electric push rod 2 592 pushes the tapered rods 594 at the lower end of the bottom plate 593 into the ground, so as to achieve the effect of limiting and fixing the device. By setting the fixing assembly 59, the device can be limited and fixed to prevent the device from being easily displaced and shaken by vibration.
