The medium frequency power supply 1 is electrically connected to the heating machine 2. A smelting furnace 3 is fixed inside the heating machine 2. It should be noted that the medium frequency power supply 1, the heating machine 2 and the smelting furnace 3 are all well-known technologies for those skilled in the art, and the utility model will not be described in detail.

The heating machine 2 is installed on the bracket 5 through an automatic flip assembly. An anti-splashing assembly is installed on the top of the heating machine 2 through a lifting and adjusting assembly.

[0022] The automatic flipping assembly includes a reducer 6, which is a transmission device for low speed and high torque. The power of the high-speed operation of the motor is achieved by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. The side end of the reducer 6 is fixed to the top of the side end of the bracket 5, and a servo motor 7 is fixed to the side end of the reducer 6. The output shaft of the servo motor 7 is fixedly connected to the input shaft of the reducer 6. A first through hole 8 is provided on the top of the side end of the bracket 5. The output shaft of the reducer 6 passes through the first through hole 8 horizontally, and a connecting plate 9 is fixed to the end of the output shaft of the reducer 6. The side end of the connecting plate 9 is fixed to the side end of the heating machine 2, and the other side end of the heating machine 2 is fixed with a rotating seat 10. The rotating seat 10 is rotatably mounted on the other side end of the bracket 5. Specifically, under the deceleration action of the reducer 6, when the servo motor 7 is running, the heating machine 2 can be driven to tilt and rotate through the connecting plate 9, thereby realizing the function of driving the smelting furnace 3 and the flow port 4 to tilt and rotate synchronously, thereby realizing the function of automatic flipping and unloading, and improving the safety of the operation;

[0023] The lifting and adjusting assembly includes two vertically arranged support rods 11, the bottom ends of the two support rods 11 are symmetrically fixed to the two side ends of the top of the heating machine 2, a top plate 12 is horizontally fixed to the top of the support rod 11, and an electric push rod 13 is vertically fixed to the middle of the top of the top plate 12. The electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. A second through hole 14 is opened in the middle of the top plate 12, and the output shaft of the electric push rod 13 vertically passes through the second through hole 14, and a lifting plate 15 is fixed to the bottom end of the output shaft of the electric push rod 13. First connecting rods 16 are symmetrically fixed to the two side ends of the bottom of the lifting plate 15, and second connecting rods 17 are fixed to the bottom ends of the first connecting rods 16. Specifically, when the electric push rod 13 is running, the first connecting rod 16 and the second connecting rod 17 can be driven to move up and down through the lifting plate 15;

[0024] The anti-splashing assembly includes a protective enclosure 18, the two side ends of the protective enclosure 18 are respectively fixed to the opposite ends of the two second connecting rods 17, and a protective cover 19 is fixed to the top of the protective enclosure 18, that is, the protective enclosure 18 and the protective cover 19 can be controlled by the electric push rod 13 to operate the lifting operation.

The protective enclosure 18 and the protective cover 19 are both located directly above the smelting furnace 3, and the bottom end of the protective enclosure 18 can be attached to the top of the smelting furnace 3 (such as Figure 4 As shown), that is, under the joint protection of the protective enclosure 18 and the protective cover 19, the high-temperature molten metal liquid can be effectively prevented from splashing during the smelting process, which greatly improves the safety of the operation and effectively avoids the waste of materials.

[0025] The usage process of the present invention is as follows: the operator first puts the metal to be smelted into the smelting furnace 3, and then starts the medium frequency power supply 1 to generate an electromagnetic field, so that the metal in the smelting furnace 3 generates heat through the induced current, thereby achieving heating and melting, and then the operator starts the electric push rod 13 to control the protective enclosure 18 and the protective cover 19 to move down to the position where the bottom end of the protective enclosure 18 is in contact with the top of the smelting furnace 3. At this time, under the joint protective effect of the protective enclosure 18 and the protective cover 19, the high-temperature molten metal liquid can be effectively prevented from splashing during the smelting process. When the metal smelting is completed, the operator first controls the protective enclosure 18 and the protective cover 19 to move up through the electric push rod 13, and then starts the servo motor 7. Under the deceleration effect of the reducer 6, when the servo motor 7 is running, it can drive the heating machine 2 to tilt and rotate through the connecting plate 9, thereby realizing the function of driving the smelting furnace 3 and the flow port 4 to tilt and rotate synchronously, thereby realizing the function of automatic flipping and unloading, greatly improving the safety of the operation, and effectively avoiding the waste of materials, and having better practicality.
