S2: stirring and mixing the raw materials:

after the raw materials fall into the inside of the mixing tank (1), the first motor (51) is started through the controller, so that the stirring shaft (50) is driven to rotate, as the stirring shaft (50) is fixedly connected with the pipe hoop (520), the two stirring plates (521) are further enabled to rotate to stir the raw materials, the raw materials are enabled to be mutually fused, the mixing rate is improved, and the stirring dead angles are avoided due to the fact that the stirring shaft (50) is mutually stirred with the pipe hoop (520);

s3: synchronous adsorption of dust during stirring:

while the stirring shaft (50) rotates to drive a plurality of stirring plates (521) to stir, as the bottom end of the stirring shaft (50) is fixedly connected with the second driving wheel (630), the second driving wheel (631) is fixedly connected with the bottom end of the second rotating rod, the second driving wheel (630) and the second driven wheel (631) are sleeved with each other through a second belt (632), a first bevel gear (633) is fixedly connected with the top end of the second rotating rod, a second bevel gear (634) is fixedly connected with one end of the rotating shaft, the other end of the rotating shaft is fixedly connected with a fan (62), the first bevel gear (633) is meshed with the second bevel gear (634), the second driving wheel (630) is larger than the second driven wheel (631), the first bevel gear (633) is larger than the second bevel gear (634), and then the fan (62) rotates at high speed, so that under the air inlet effect of the air inlet pipe (21) is realized, dust generated when raw materials are mixed is synchronously sucked into the air chamber (61) through the air outlet pipe (60), and then discharged to the air chamber (61) through the grid (610), and the purity of the raw materials is guaranteed to be mixed into the air mixing tank (1) from the filter plate (1);

S4: synchronous treatment of dust during adsorption:

when the fan (62) rotates, as the rotating shaft is fixedly connected with the third driving wheel (730), the second hinging shaft is fixedly connected with the third driven wheel (731), the third driving wheel (730) and the third driven wheel (731) are sleeved and connected through a third belt (732), so that the third hinging shaft is driven to rotate anticlockwise, as the turntable (740) and one end, far away from the third driven wheel (731), of the third hinging shaft are fixedly connected, the turntable (740) and the butt joint block are hinged with two ends of the connecting rod (741), the butt joint block is in sliding connection with the mounting table through the sliding block (743), the butt joint block is fixedly connected with one end of the extrusion rod (742), the other end of the extrusion rod (742) is spliced with the receiving pipe (72), so that the extrusion rod (742) is driven to slide towards one end, close to the conveying pipe (700), dust suppressant in the receiving pipe (72) is extruded to the conveying pipe (700), and then sprayed from the grille (610), so that dust suppressant scattered from the grille (610) can catch dust in air, quickly moisten and enable dust to quickly infiltrate and reduce the dust concentration, and prevent dust pollution and dust pollution to the dust from the dust pollution to the environment;

S5: discharging the mixture:

after the raw materials are fully mixed, the electromagnetic valve (100) is started by the controller, and under the pushing action of the two stirring plates (521) positioned at the bottom of the inner side of the mixing tank (1), the mixed raw materials are discharged through the discharging pipe (10), so that the discharging is finished.
