When the lifting bucket 3 is rotated to the bottom end of the frame 1, the slag will be scooped up. When the lifting bucket 3 is rotated to the top end of the frame 1, the slag in the lifting bucket 3 will be thrown out from the discharge port 5 into the cart 8 under the action of centrifugal force. The weighing platform 7 is an alarm weighing platform 7. The weighing platform 7 can weigh the cart 8 and the slag inside it. When the weight of the slag reaches the specified standard, the weighing platform 7 will alarm.
