[0029] In this embodiment, a bracket 101 is fixedly provided at the bottom of the mixing barrel 100 .

[0030] It is used to support the mixing barrel 100 to ensure the stability and safety of the equipment.

[0031] Working process and principle: When the device is in use, the mixing barrel 100 serves as the main container for coal mixing, and its internal space is used to accommodate the coal to be mixed. The coal is quantitatively added through the discharging mechanism 200 on the side wall, and the second motor 202 drives the semicircular block 214 and the half gear 213 to rotate. The meshing connection between the half gear 213 and the gear 211 drives the rotating shaft 210 and the first turntable 205 to rotate. The first coal storage barrel 206 on the first turntable 205 rotates accordingly. When the first coal storage barrel 206 is aligned with the feed hopper 204, the coal enters the first coal storage barrel 206 through the feed hopper 204, and then the coal enters the second coal storage barrel 208. When the semicircular block 214 is engaged with the gear 213, the first coal storage barrel 206 is engaged with the gear 211, and the first coal storage barrel 206 is engaged with the gear 211. When 214 is matched with the shift block 212, when the second coal storage barrel 208 rotates to the set position, the connecting block 218 moves to the notch 220 of the shift block 219, and the connecting block 218 opens the barrel cover 209 through the hinge block 217, and the coal is intermittently discharged into the mixing barrel 100, and then the first motor 102 drives the connecting plate 310 and the rotating rod 304 to rotate, and the rotating rod 304 drives the moving block 305 and the stirring rod 306 to move on the screw 303. At the same time, the stirring rod 306 and the dispersion rod 307 stir and disperse the coal in the mixing barrel 100 to achieve uniform mixing, which effectively solves the problem of uneven mixing and improves the quality stability of the mixed coal. After mixing is completed, the coal is discharged through the discharge port 103 at the bottom for subsequent use. When the proportion of coal needs to be adjusted, the third motor 216 drives the rotating rod 229 and the adjusting gear 230 to rotate, and the rack 227 engaged with the adjusting gear 230 drives the fixed rod 225 to move, thereby adjusting the overlapping distance between the first coal storage barrel 206 and the second coal storage barrel 208. The size of the coal storage barrel is adjusted as needed to adjust the coal discharge amount.
