[0068] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0069] Embodiment 1:

[0070] like Figure 1-Figure 7 As shown, the automatic alloy feeding equipment of this embodiment includes a first platform 1, a plurality of silos 4, a belt conveyor 7, a plurality of sliding support seats 8, a material guide pipe 6 and a lifting mechanism 5.

[0071] The second platform 2 is located above the first platform 1;

[0072] A plurality of silos 4, wherein the plurality of silos 4 are located in the middle of the second platform 2, and the upper end of the silo 4 is located above the second platform 2;

[0073] The belt conveyor 7 is located between the first platform 1 and the second platform 2. The lower end of the silo 4 passes through the second platform 2 and is located above the belt conveyor 7. The plurality of silos 4 are arranged along the conveying direction of the belt conveyor 7.

[0074] A plurality of sliding support seats 8 are installed on the first platform 1 and are slidably connected to the belt conveyor 7, and the sliding support seats 8 are used to support the belt conveyor 7;

[0075] The material guide pipe 6 is located outside one end of the conveying direction of the belt conveyor 7;

[0076] A lifting mechanism 5 is installed on the first platform 1, and is used to drive the material guide pipe 6 to move up and down;

[0077] Among them, the first platform 1 outside the belt conveyor 7 forms a first standing surface, which is used for operators to stand when maintaining the belt conveyor 7; the second platforms 2 outside the multiple silos 4 form a second standing surface, which is used for operators to stand when adding materials to the silos 4.

[0078] Specifically, the bottom of the first platform 1 is fixedly installed by a supporting frame so that the lifting mechanism 5 is suspended in the air, and the second platform 2 is fixedly connected to the first platform 1 by a structural member. The ladle to be added with alloy material can be moved to the bottom of the lifting mechanism 5, and the lifting mechanism 5 drives the material guide pipe 6 to descend and then extend into the molten iron ladle.

[0079] The automatic alloy feeding equipment of this embodiment is designed with a double-layer standing table, and the silo 4 passes through the second platform 2 longitudinally, reducing the height of the upper end of the silo 4 from the second standing table, and when the operator stands on the second standing table to pour the alloy material in the material bag into the silo, it is more labor-saving;

[0080] A plurality of sliding support seats 8 are located on both sides of the belt conveyor 7. The sliding support seats 8 on one side are arranged at intervals along the conveying direction of the belt conveyor 7.

Silos 4 of different sizes ensure that the feeding rate of each silo 4 does not deviate much during automatic feeding, thereby ensuring the production rhythm. For example, multiple silos 4 can be used to store fine spheroidizing agent, coarse spheroidizing agent and silicon material in turn. The silo 4 for storing fine spheroidizing agent is located on one side of the lifting mechanism 5. Multiple silos 4 realize feeding at multiple positions, thereby improving working efficiency.
