[0002] The automatic feeder of the submerged arc furnace plays a vital role in the modern smelting industry. It is a device used to accurately control the feeding of raw materials into the submerged arc furnace. In existing designs, automatic feeders mostly rely on mechanical arms or conveying mechanisms to transport and feed raw materials, but these devices are often inflexible or inefficient when dealing with raw materials of different sizes and adjusting the feeding width and height.

[0003] Common automatic feeders for submerged arc furnaces mostly use fixed-structure support frames, which can only adapt to raw materials and feeding requirements of specific sizes, and have limited adjustment range and poor versatility. At the same time, the clamping and fixing of power components such as hydraulic telescopic columns are often difficult to meet diverse usage scenarios due to the lack of flexible adjustment mechanisms. Therefore, a hydraulic push-tilt mechanism for automatic feeders for submerged arc furnaces is proposed to solve the above-mentioned problems. Utility Model Content

[0026] The adjustment assembly includes a first connecting plate 2, a second connecting plate 3, an adjusting screw 5 and a clamping block 6. The first connecting plate 2 is arranged inside each group of support members 1, and the second connecting plate 3 is arranged between the two groups of support members 1. The adjusting screw 5 passes through an end angle of the support member 1 and is rotatably connected to the clamping block 6 inside the support member 1 through a bearing.

[0027] In this embodiment, the support member 1 is composed of a circular frame 101 and four guide plates 102 with top openings. The inner circle and the outer circle of the circular frame 101 are both square, and the four guide plates 102 are welded to the top of the circular frame 101 in a circumferentially distributed manner.

[0028] It should be noted that the top opening design of the guide plate 102 facilitates the plugging and fixing with the second connecting plate 3, thereby enhancing the integrity of the structure and the convenience of assembly. The square design of the circular frame 101 ensures the strength and stability of the support member 1, and is able to withstand the thrust generated by the hydraulic telescopic column 8 during operation.

[0029] In this embodiment, each group of two adjacent return frames 101 are close to each other and have one side open. The two ends of the first connecting plate 2 are respectively plugged into the open ends of the two return frames 101 and then fixed with fixing screws 4 .

[0030] In this embodiment, two unopened corners of the return frame 101 are provided with rectangular protrusions 103 , the adjusting screw 5 is threadedly connected to the rectangular protrusions 103 , and nuts 7 are bolted to both sides of the rectangular protrusions 103 .
