[0019] A method for using a ore bin unloading device comprises the following steps: Step 1: Rotate the material distribution baffle 12 so that a gap suitable for the material to fall appears at the ends of the two material distribution baffles 12; Step 2: After the materials on the belt conveyor enter the material distribution bin 101, they fall on the extended belt through the gap between the ends of the two material distribution baffles 12 through the middle channel 104 and are then transported to the ore bin.

[0020] Embodiment 1, Taking the setting of three ore bins as an example, the left and right extension channels 103 are connected to the No. 1 and No. 2 ore bins for unloading, respectively, and the middle channel 104 is connected to the No. 3 ore bin for unloading. The upper end of the partition wall between the No. 1 and No. 2 ore bins is in an inverted V shape, and the left and right extension channels 103 are respectively facing the tip of the inverted V shape. The four-way channel 1 is composed of the distribution bin 101 and the middle channel 104 connected to its bottom, the two side channels 102 and the extension channel 103 to form an integrated through structure, thereby forming an inverted Y-shaped channel with a connected front section. The two side channels 102 are inclined to improve the transmission efficiency and reduce material accumulation. The vertically arranged extension channel 103 can further improve the material transportation efficiency and increase stability. The size of the four-way channel 1 matches the connected ore bin, and the distribution baffle 12 and the adjustment baffle 13 are square plate structures, and the size matches the internal size of the four-way channel 1.
[0021] Circular through holes and fixing holes are respectively provided at the lower part of the material dividing baffle 12 and the middle part of the adjusting baffle 13. Multiple second circular holes 20 are respectively provided at the middle part of the first rotating rod 31 and the second rotating rod 32.

The middle part of the adjusting baffle 13 is fixedly connected to the second rotating rod 32 through the second circular holes 20, the circular through holes, the fixing holes and the matching bolts 7, which ensures the connection effect while facilitating disassembly and maintenance.
[0022] The two ends of the first rotating rod 31 and the second rotating rod 32 extend out of the side walls of the side channel and the extension channel 103 respectively, and a sleeve 4 is provided on the side wall. The sleeve 4 is symmetrically welded and installed on the outer wall of the side channel 102, and the other two groups are symmetrically welded and installed on the outer wall of the extension channel 103. A bearing 5 is arranged in the sleeve 4, and the size of the bearing 5 matches that of the sleeve 4. The bearing 5 is a sealed bearing, which is welded and installed in the sleeve 4, and can effectively prevent dust and materials from entering, thereby ensuring the rotation effect of the bearing 5. The two extension ends are respectively provided with bearings 5 to make the rotation process easier and improve work efficiency. The diameter of the first rotating rod 31 and the second rotating rod 32 matches the inner hole of the bearing 5.
[0023] The driving mechanism 6 is composed of an electric hydraulic telescopic rod 17 and a connecting rod 18. The connecting rod 18 is a rectangular structure with first circular holes 16 at both ends. The end of the first rotating rod 31 extending out of the outer wall of the side channel 102 is threaded. One end of the connecting rod 18 is rotatably connected to the threaded end of the first rotating rod 31 through the first circular hole 16 and is fixed with a nut 8. The other end of the connecting rod 18 has an arc and is fixedly connected to the output end of the electric hydraulic telescopic rod 17 through the first circular hole 16. The electric hydraulic telescopic rod 17 is set on the outer wall of the side channel 102 through the base 19 and the bolt 7. The electric hydraulic telescopic rod 17 is started to push the connecting rod 18, so that it drives the first rotating rod 31 and the material distribution baffle 12 to flip.
[0024] The limiting card plate 9 is L-shaped from the front view and semicircular from the side view. A plurality of limiting grooves 21 are evenly arranged on the semicircular part. The long part of the limiting card plate 9 is welded and fixed to the outer wall of the extension channel 103, and the semicircular part is in the same direction as the operating handle 10. The operating handle 10 is rectangular, with a square hole 22 in the middle, and the lower end is welded and fixed to one end of the second rotating rod 32; the fixing device 11 is a T-shaped structure, and the size matches the limiting groove 21 and the square hole 22 of the operating handle 10.
[0025] By rotating the operating handle 10 to drive the second rotating rod 32 to adjust the angle of the adjusting baffle 13, and fixing it with the fixer 11, the material transportation volume of the materials in the left and right extension channels 103 in the direction of the parallel ore bins can be adjusted. The four-way channel 1, the material dividing baffle 12, the adjusting baffle 13, the first rotating rod 31, the second rotating rod 32, the sleeve 4, the bearing 5, the driving mechanism 6, the bolt 7, the nut 8, the limit clamp 9, the operating handle 10 and the fixer 11 are all made of steel.
[0026] When the unloading device of the present invention is used to transport materials on the belt conveyor and unload them to the ore bin, the materials fall into the sub-bin 101 through the belt conveyor, and the sub-bin 12 is driven to rotate by the electric hydraulic telescopic rod 17, the connecting rod 18, and the first rotating rod 31. When the sub-bin 12 in the side channels 102 on both sides rotates to a certain angle to form a gap, the belt conveyor passes through the belt head roller 23 and then through a redirecting roller 24, passes through the inverted Y-shaped middle gap of the four-way channel 1, and continues to extend to the No. 3 ore bin. Figure 2 In the direction indicated by the middle arrow, the material falls onto the belt conveyor below through the middle channel 104 and is finally unloaded into the No. 3 ore bin. At the same time, the material falls into the No. 1 and No. 2 ore bins through the side channels 102 on both sides through the extension channels 103, thereby realizing the operation requirement of transporting materials to the three ore bins at the same time.
[0027] By operating the handle 10 to rotate the adjustment baffle 13 and the inner wall of the extension channel 103 to form gaps of different spacings, and using the fixer 11 to snap into the limit groove 21 for fixation, the left and right extension channels 103 can be adjusted in the direction of the No. 1 and No. 2 ore bins connected in parallel with them. The material transportation requirements of the No. 1, No. 2 and No. 3 ore bins can be effectively achieved.
