Step S2, then control the second motor (605) through the control panel (10) is opened, then pour into the electrolytic aluminum raw material into the hopper (3), electrolytic aluminum raw material through the hopper (3) drop into the conveyor belt (603), under the drive of the second motor (605), the electrolytic aluminum raw material is transported to the first discharge port (101), through the collection box for the collection of electrolytic aluminum raw material; Step S3, when the need to change the conveying mode, at this time through the control panel (10) control electric push rod (506) and the third motor (905) is opened, before pouring into the hopper (3) in electrolytic aluminum raw material, through the arc-shaped push block (507) of electric push rod (506) to move forward, through the movement of the arc-shaped push block (507) will push the first guide plate (504) from the vertical state to rotate to the inclined state, when the first guide plate (504) and the second guide plate (8) parallel, electric push rod (506) stop driving arc-shaped push block (507), then pour into the hopper (3) in electrolytic aluminum raw material, at this time the electrolytic aluminum raw material through the first guide plate (504) and the second guide plate (8) into the guide bin (7), under the cooperation of the third motor (905) and spiral blade (906), the electrolytic aluminum raw material into the transmission bin (901) is stirred and transported, finally the electrolytic aluminum raw material through the second discharge port (102) flow, through artificial collection can be; Step S4, when the need to control the conveying speed, through the control panel (10) control the first motor (4010) is opened, under the drive of the first motor (4010), the rotating block (407) will not stop rotating, rotating block (407) every rotation, adjusting block (403) will move up and then move down, then move up and finally move down; through the movement of the adjusting block (403), the speed of the electrolytic aluminum raw material can be controlled, so as to realize the purpose of changing the raw material conveying speed through the speed of the raw material.
