The right hopper 2 and the left hopper 3 are symmetrical. The opening side wall of the right hopper 2 and the opening side wall of the left hopper 3 are joined together to form a cylinder with an opening on the top surface. A rear support I 201 and a side support I 202 are fixedly connected to the outer wall of the right hopper 2. The rear support I 201 is located on the rear outer wall of the right hopper 2, and the side support I 202 is located in front of the rear support I 201. A rear support II 301 and a side support II 302 are fixedly connected to the outer wall of the left hopper 3. The rear support II 301 is located on the rear outer wall of the left hopper 3, and the side support II 302 is located in front of the rear support II 301. The support rod 4 includes a square tube 401 and a support seat I 402. The support seat I 402 is located at the front end of the square tube 401. Rectangular holes I 403 are provided on the left and right parallel side walls of the square tube 401. The rear support I 201 and the rear support II 301 are rotatably connected to the support seat I 402 by pins. The push-pull rod 5 is slidably connected inside the square tube 401 and slides along the length of the square tube 401. The push-pull rod 5 includes a straight rod 501 and a support seat II 502. The support seat II 502 is located at the front end of the straight rod 501. There are two push-pull pieces 6. The rear ends of the two push-pull pieces 6 are rotatably connected to the support seat II 502 by pins. The two push-pull pieces 6 are respectively located in the two rectangular holes I 403. The front ends of the two push-pull pieces 6 are rotatably connected to the side support I 202 and the side support II 302 by pins, respectively.

[0031] The rear support I 201 has a pin hole I 203, the rear support II 301 has a pin hole III 303, and the support I 402 has a pin hole V 404. Pin holes I 203, III 303, and V 404 are coaxial, and a connecting pin II 8 is inserted into all three pin holes. The rear support I 201 is positioned above the rear support II 301, and the support I 402 is positioned above the rear support I 201, along the axial direction of pin holes I 203, III 303, and V 404.

[0032] Both push-pull tabs 6 have pin holes VII 601 at their rear ends, and the support base II 502 has pin holes VI 503. Pin holes VI 503 are coaxial with the two pin holes VII 601, and a connecting pin I 7 is inserted into both pin holes VI 503 and the two pin holes VII 601. The two push-pull tabs 6 are respectively located above and below the support base II 502.

[0034] In use, the push-pull rod 5 is first pulled backward to align the opening sidewall of the right hopper 2 with the opening sidewall of the left hopper 3, thereby closing the hopper assembly 1. Figure 1 As shown, the columnar metal additive is placed inside the hopper assembly 1. The worker holds the rear of the support rod 4 and places the hopper assembly 1 above the molten aluminum in the smelting furnace. The push-pull rod 5 is pushed forward, causing the two push-pull plates 6 to move. Since the rear supports I 201 and II 301 are rotatably connected to the support I, the movement of the two push-pull plates 6, through the side supports I 202 and II 203, causes the right hopper 2 and left hopper 3 to rotate in opposite directions around the connecting pin II 8, thus opening the hopper assembly 1. Figure 9 As shown, after the hopper assembly 1 is opened, the columnar metal additive inside falls into the molten aluminum, thereby realizing the addition of the columnar metal additive.

[0035] When using this invention, workers can precisely add metal additives to different positions in the molten aluminum, thereby achieving uniform metal additive distribution within the molten aluminum and ensuring the production quality of aluminum alloys in the smelting furnace.

[0036] When using this invention, the columnar metal additive is added close to the molten aluminum, which reduces the splashing of molten aluminum caused by the metal additive being thrown into the molten aluminum. During operation, the operator holds the rear of the support rod 4 and keeps away from the molten aluminum, thereby preventing the operator from being burned by the splashed molten aluminum and ensuring work safety.

[0037] The push-pull rod 5 includes a support rod 504, which is fixedly connected to the bottom of the straight rod 501. The support rod 504 is located at the rear of the straight rod 501. A rectangular hole II 405 is provided on the bottom surface of the rear of the support rod 4. The length direction of the rectangular hole II 405 is set along the length direction of the support rod 4. The support rod 504 is slidably connected in the rectangular hole II 405 and extends out of the rectangular hole II 405.

[0038] The support rod 504 is designed to facilitate the operation of the push-pull rod 5 by the staff. When in use, the staff can hold the support rod 504 by hand, which improves the ease of use of this utility model and further enhances its stability.

[0039] A support seat Ⅲ10 is fixedly connected to the inner bottom surface of the square tube 401. The support seat Ⅲ10 is provided with a sliding hole 1001, and the straight rod 501 is slidably connected in the sliding hole 1001. There are multiple support seats Ⅲ10, which are evenly distributed along the length of the square tube 401. Each support seat Ⅲ10 is provided with a sliding hole 1001, and the straight rod 501 is slidably connected in the multiple sliding holes 1001.

[0040] The support base Ⅲ10 and the sliding hole 1001 provide support for the forward and backward sliding of the push-pull rod 5, ensuring the stability of this utility model in use.

[0041] A bottom hole 406 is provided on the rear side wall of the square tube 401, and the rear end of the straight rod 501 is slidably connected in the bottom hole 406, with the rear end of the straight rod 501 extending out of the bottom hole 406.

[0042] The bottom hole 406 is designed to prevent interference between the rear end of the straight rod 501 and the square tube 401.

[0043] Both the right hopper 2 and the left hopper 3 have a semi-funnel shape at the bottom, with one side wall open. The funnel-shaped bottom allows all the additives to fall out, preventing accumulation and residue. In this embodiment, the semi-funnel-shaped ground at the bottom of the right hopper 2 and the left hopper 3 also has a semi-funnel-shaped bottom surface, with the bottom surface forming an angle of 10° with the horizontal plane.

[0044] In this embodiment, all components are made of Q235 stainless steel.
