s2, hoisting the feeding hopper (1) by using a lifting hook device, then opening the bottom cover device (8), and if the material ingot in the feeding hopper (1) slides downwards in the opening process of the bottom cover device (8), controlling the air pressure rod (5) to further push the tensioning device (3) until the material ingot does not slide downwards;
s3, if the ingots still slide down after the air compression rod (5) further pushes the tensioning device (3) in the step S2, closing the bottom cover device (8), simultaneously placing the loading hopper (1) on the ground by using a lifting hook device, changing the distribution of the ingots in the loading hopper (1), then repeating the step S2 until the ingots in the loading hopper (1) do not slide down, and then starting the step S4;
s4, controlling a lifting hook device to align the blanking hopper (12) with the opening of the crucible, then placing the bottom of the blanking hopper (12) into the opening of the crucible, then opening an electromagnetic valve on a pneumatic rod (5) to release gas in the pneumatic rod (5), resetting a resetting device (2) to enable a contraction band (71) to release the ingot, and enabling the ingot to fall into the crucible integrally;
s5, the loading hopper (1) is hoisted back to the initial position by using a hook device.
