step three: the charging barrel 23 is moved to the weighing plate 22 through the same operation, at the moment, the first hydraulic rod 7 moves downwards to the limiting column 17 to move from the limiting hole 29, the second hydraulic rod 13 contracts to realize the separation of the limiting column 17 and the charging barrel 23, and raw materials are added into the charging barrel 23 for weighing.

The rotating plate 11 is driven to move downwards by the expansion of the first hydraulic rod 7 on the sliding plate 3 until the rotating plate 11 is contacted with the top end of the charging barrel 23, at the moment, the arc-shaped block 14 is driven to move by the second hydraulic rod 13 on the side plate 12 until the ball of the arc-shaped block 14 is contacted with the side wall of the charging barrel 23, the limiting column 17 is contracted by the second hydraulic rod 13 until the limiting column 17 is contacted with the bottom side of the outer ring 28, and when the rotating plate continuously moves upwards, the limiting column 17 compresses the first spring 16 in the limiting groove 15, the first motor 10 in the lifting seat 8 works to drive the rotating plate 11 to rotate, the limiting column 17 rotates at the bottom side of the outer ring 28 through the ball, when the limiting column 17 is matched with the limiting hole 29, the first spring 16 is restored to the original state, the limiting column 17 is clamped into the limiting hole 29, the charging barrel 23 is ensured to be tightly connected with the rotating plate 11, the limiting column 17 plays a role of limiting reinforcement, the situation that the charging barrel 23 falls off when the moving is avoided, and simultaneously, the first hydraulic rod 7 moves downwards to the limiting column 17 to move from the limiting hole 29, the second hydraulic rod 13 contracts to realize the separation of the limiting column 17 and the charging barrel 23, so that the practical operation and application are facilitated;

the charging barrel 23 moves downwards under the operation of the first hydraulic rod 7, the ring seat 33 is firstly contacted with the top side of the smelting furnace 5 or the weighing plate 22, when the ring seat moves downwards continuously, the guide rod 31 connected with the ring seat 33 moves upwards in the fixing ring 30 to compress the second spring 32, the buffering effect is achieved through the elastic deformation of the second spring 32 until the bottom side of the bearing plate 24 is contacted with the top side of the smelting furnace 5, the elastic contact is achieved, the problem that the charging barrel 23 is in hard contact with the smelting furnace 5 and the weighing plate 22 to cause structural damage is avoided, the third motor 27 on the second mounting plate 26 works to drive the first mounting plate 25 and the bearing plate 24 to rotate until the bearing plate 24 is moved away from the bottom end of the charging barrel 23, raw materials in the charging barrel 23 automatically fall into the smelting furnace 5, then the bearing plate 24 rotates to the bottom end of the charging barrel 23, and rapid discharging is achieved.
