[0028] The effect achieved by the entire embodiment 1 is that by starting the first drive motor 14, the first drive motor 14 drives the first rotating shaft 11 to rotate, and the first rotating shaft 11 drives the gear 12 to rotate. Since the gear 12 is meshed with the rack 13, it drives the bracket 10 to move upward, and the bracket 10 drives the cover plate 7 to move upward. By lifting the cover plate 7 upward, it is convenient to add rare earth and metal into the mixing bucket 3, and then by starting the first drive motor 14, the bracket 10 drives the cover plate 7 to move downward, so that the cover plate 7 can cover the top of the mixing bucket 3. The operation is convenient and the practicality is improved. At the same time, the fixed rod 6 is set to limit the cover plate 7 so that the cover plate 7 can remain stable during the movement, solving the problem that the existing device is inconvenient to add rare earth and metal into the lower hopper when in use, inconvenient to load materials, reduced convenience, and thus affecting work efficiency.

[0029] Example 2: Figure 1 - Figure 5 As shown, the stirring mechanism 8 includes a second drive motor 801, which is fixedly mounted on the top of the cover plate 7. The output end of the second drive motor 801 is fixedly connected to the second rotating shaft 802. The bottom end of the second rotating shaft 802 movably passes through the cover plate 7. The outer surface of the second rotating shaft 802 is fixedly connected to a scraper 803. The outer surface of the second rotating shaft 802 is fixedly connected to a stirring plate 804. The outer surface of the second rotating shaft 802 is fixedly connected to an auger 805. A through hole 15 is provided on the top of the mounting cover 2. The stirring bucket 3 is connected to the interior of the furnace body 1 through the through hole 15.

A blocking block 903 is fixedly connected between the two connecting plates 902. The mounting cover 2 is threadedly connected to the outer top of the furnace body 1, and the rack 13 is meshed with the gear 12. The outer surface of the mounting cover 2 is fixedly connected to a connecting rod 16, and one end of the connecting rod 16 is fixedly connected to a ring block 17. The top of the fixed rod 6 is fixedly connected to a limiting plate 18, and the fixed rod 6 is slidably connected to the cover plate 7.

[0030] The effect achieved by the entire embodiment 2 is that, through the stirring mechanism 8, the second driving motor 801 is started, so that the second driving motor 801 drives the second rotating shaft 802 to rotate, and the second rotating shaft 802 drives the scraper 803 and the stirring plate 804 to rotate synchronously, and the rotating scraper 803 is convenient for scraping off the material adhering to the inner wall of the stirring bucket 3, thereby improving the uniformity of stirring, and the rotating stirring plate 804 is convenient for fully stirring the material in the stirring bucket 3, and then through the blocking mechanism 9, the outer surface of the blocking block 903 is provided with a sealing coating, and the blocking block 903 is located at the through hole 15. Inside, it is convenient to block the rare earth and metal raw materials to prevent them from falling. When the rare earth and metal in the stirring bucket 3 are mixed, the electric push rod 901 is started to extend, so that the connecting plate 902 drives the blocking block 903 to move downward and leave the through hole 15, so that the mixed rare earth and metal in the stirring bucket 3 fall into the furnace body 1 through the through hole 15, which is convenient for smelting. Then, the installation cover 2 is threadedly connected to the outer top of the furnace body 1. The user holds the ring block 17 and rotates it forward or reversely to facilitate the installation and removal of the furnace cover from the outer surface of the smelting furnace. The limit plate 18 is then used to limit the cover plate 7 to prevent the cover plate 7 from falling off.

[0031] Working principle: When in use, first start the first drive motor 14, so that the first drive motor 14 drives the first rotating shaft 11 to rotate, and the first rotating shaft 11 drives the gear 12 to rotate. Since the gear 12 is meshed with the rack 13, the bracket 10 is driven to move upward, and the bracket 10 drives the cover plate 7 to move upward. After the cover plate 7 is lifted upward, the rare earth and metal are added to the mixing bucket 3, and then the first drive motor 14 is started, so that the bracket 10 drives the cover plate 7 to move downward, so that the cover plate 7 covers the top of the mixing bucket 3, and then the second drive motor 801 is started, so that the second drive motor 801 drives the second rotating shaft 802 to rotate, and the second rotating shaft 802 drives the scraper 803, the stirring plate 804 and The auger 805 rotates synchronously, the rotating stirring plate 804 fully stirs the material in the stirring bucket 3, and the rotating scraper 803 scrapes off the material adhering to the inner wall of the stirring bucket 3, thereby improving the uniformity of stirring. When the rare earth and metal in the stirring bucket 3 are mixed, the electric push rod 901 is started to extend, so that the connecting plate 902 drives the blocking block 903 to move downward and leave the through hole 15. At the same time, as the auger 805 rotates, the mixed rare earth and metal in the stirring bucket 3 fall into the furnace body 1 through the through hole 15 for smelting, which is convenient for stirring and mixing the rare earth and metal in advance. There is no need to stir and mix them again inside the smelting furnace, which prevents other substances from mixing into the rare earth alloy and protects the purity of the rare earth alloy.
