At the same time, the side plate 24 will block the splashed molten steel, allowing it to return to the interior of the steelmaking furnace 1 along the funnels 21. When the molten steel content inside the steelmaking furnace 1 is high, more molten steel will splash up when feeding. By adding an extension rod 25, the guard plate 26 can be fixed to the top surface of the side plate 24, which helps to further block the splashed molten steel. The sliding rod 28 can be driven by the base mechanism 3 to move the funnels 21 away from the surface of the steelmaking furnace 1, so that other work can be performed on the steelmaking furnace 1.

[0027] Example 2

[0028] like Figures 1-5As shown in the embodiment 1, on the basis, the utility model provides a technical scheme: preferably, the gas collecting device 27 includes filter screen 271, the filter screen 271 fixedly connected in the inside side of side plate 24, the quantity of filter screen 271 is two, and the other filter screen 271 is fixedly connected in the inside other side of side plate 24, the output of filter screen 271 is fixedly connected with gas collecting pipe 272, the side of gas collecting pipe 272 is fixedly connected with suction pipe 273, the side of suction pipe 273 is fixedly connected with shell 274, shell 274 is fixedly connected in the side of anti-drop plate 29, the inside of shell 274 is fixedly connected with support 275, the inside of support 275 is fixedly connected with motor 276, the output of motor 276 is fixedly connected with fan blade 277, the side of shell 274 is fixedly connected with gas inlet 278.

[0030] Embodiment 3

[0031] As Figures 1-5 As shown in the embodiment 1, on the basis, the utility model provides a technical scheme: preferably, the base mechanism 3 includes slide rail 32, the slide rail 32 movably connected in the bottom surface of pulley 23, the bottom surface of slide rail 32 is fixedly connected with base 31, the inside side of base 31 is fixedly connected with waste bin 33, one end of the top surface of base 31 is fixedly connected with power device 34, power device 34 includes fixed frame 341, and the fixed frame 341 is fixedly connected in the top surface of base 31, and the inside of fixed frame 341 is provided with sliding slot 342, and slide rod 28 is slidably connected in the inside of sliding slot 342, and gear 343 is rotatably connected in the inside of fixed frame 341, and gear 343 is engaged with the inside toothed groove of slide rod 28 bottom surface, and the side of fixed frame 341 is fixedly connected with drive motor 344, and one end of gear 343 penetrates the side of fixed frame 341 and is fixedly connected in the output end of drive motor 344.

[0032] In this embodiment, the slide rail 32 is fixed to the bottom surface by the base 31 to make it stable. The drive motor 344 drives the gear 343 to rotate, so that the slide rod 28 can drive the funnel 21 and the side plate 24 to move left and right under the rotation of the gear 343. At the same time, the slide groove 342 will ensure that the slide rod 28 will not deviate.

This makes the two funnels 21 form a complete arc surface. When feeding, the material passes through the buffer of the funnel 21, reducing the impact force of the material entering the steelmaking furnace 1 and reducing the splashing of molten steel inside the steelmaking furnace 1. At the same time, the side plate 24 blocks the splashed molten steel, allowing it to return to the interior of the steelmaking furnace 1 along the funnel 21. When the molten steel content inside the steelmaking furnace 1 is high, more molten steel will splash up during feeding. By adding an extension rod 25, the guard plate 26 can be fixed to the top surface of the side plate 24, which helps to further block the splashed molten steel. The slide bar 28 can be driven by the base mechanism 3 to move the funnel 21 away from the surface of the steelmaking furnace 1 so that other work can be carried out on the steelmaking furnace 1. The motor 276 drives the fan blade 277 to draw in air, so that the toxic gas generated inside the steelmaking furnace 1 is drawn into the interior of the outer shell 274 and connected to the indoor exhaust system through the air inlet 278 to ensure the protection of workers. The filter screen 271 will prevent molten steel from entering the interior of the gas collecting pipe 272. When the protective mechanism 2 starts to move, the pulley 23 will roll inside the slide rail 32 to make the movement of the device smoother. When impurities accumulate inside the funnel 21 and the side plate 24, they can be removed in the retracted state. The fallen impurities will accumulate inside the slide rail 32 for easy handling.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
