[0034] There are two electric telescopic rods 8 , which are installed on one side of the rotating drum 2 and electrically connected to the numerical control box 9 . The telescopic ends of the two electric telescopic rods 8 are fixedly mounted with a gate plate 81 for sealing the discharge port 101 .

[0035] It should be noted that: when in use, the light aggregate is placed in the feed funnel 4, and then the predetermined light aggregate weight is set through the CNC box 9, and then the servo motor 32 is started to drive the discharge impeller 31 to discharge the light aggregate in the feed funnel 4 to the supporting plate 54 of the weighing component 5, and the supporting plate 54 uses a pressure sensor 55 to monitor the weight of the light aggregate on the supporting plate 54 in real time until it reaches the set weight, and then the rotating motor 52 is controlled to drive the support shaft 51 to rotate, and the support shaft 51 drives the partition plate 53 to rotate until the light aggregate on the supporting plate 54 is discharged from the feed port in the premixing box 1 into the premixing box 1.
