[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 3 , in the embodiment of the present invention, the slag receiving bucket mechanism of the intermediate frequency furnace includes a slag receiving bucket 1. A reduction motor 2 is installed on the outer wall of the slag receiving bucket 1 through a mounting bracket. A transfer bucket 3 is arranged above the slag receiving bucket 1, and a limiting mechanism 4 is arranged on the slag receiving bucket 1 and the transfer bucket 3;

[0029] The limiting mechanism 4 includes a limiting unit and a blanking unit;

[0030] The limiting unit is used to quickly self-limit the transfer bucket 3;

[0031] The blanking unit is used to turn over and pour the transfer bucket 3 after the limiting is completed;

[0032] The blanking unit includes a rotating rod 401 and a mounting bracket 402;

[0033] The rotating rod 401 is connected to the output end of the reduction motor 2 through a rotating shaft and a coupling and extends into the slag receiving bucket 1. The rotating rod 401 is used to drive the mounting bracket 402 to rotate;

[0034] The mounting bracket 402 is fixed on the outer wall of the rotating rod 401. The mounting bracket 402 is used to provide a space for placing the transfer bucket 3;

[0035] The limiting unit includes a fixed block 403, a limiting rod 404, a spring 405, and an abutting block 406;

[0036] The fixed block 403 is fixed on the outer wall of the mounting bracket 402. The fixed block 403 is used to provide support for the rotation of the limiting rod 404;

[0037] The limiting rod 404 is rotatably installed inside the fixed block 403 and extends above the transfer bucket 3. The limiting rod 404 is used to limit the flipped transfer bucket 3;

[0038] Both ends of the spring 405 are respectively clamped on the inner wall of the fixed block 403 and the outer wall of the limiting rod 404, and the spring 405 is used to always apply a pulling force to the limiting rod 404;

[0039] The abutting block 406 is fixed on the outer wall of the transfer barrel 3, and the abutting block 406 is used to apply an outward pushing force to the limiting rod 404 during the rotation of the transfer barrel 3 to release the limit.

[0040] In this embodiment: When using this device, after manually pouring the slag into the transfer barrel 3, the transfer barrel 3 is directly manually moved to the inside of the mounting frame 402. When the transfer barrel 3 enters the inside of the mounting frame 402, it will contact the inclined surface at the top end of the limiting rod 404, applying a pushing force to the limiting rod 404 to move to both sides. The stressed limiting rod 404 will rotate around the connection point with the fixed block 403 as the axis. The rotating limiting rod 404 applies a pulling force to the inclined spring 405 until the transfer barrel 3 completely enters the inside of the mounting frame 402, and the limiting rod 404 will also return to its original position under the pulling force of the spring 405. At this time, the flat straight surface at the bottom end of the end of the limiting rod 404 is above the transfer barrel 3. By starting the reduction motor 2 to drive the rotating rod 401 to rotate, the rotating rotating rod 401 synchronously drives the mounting frame 402 to rotate, so that the transfer barrel 3 inside the mounting frame 402 rotates synchronously to pour the slag inside the transfer barrel 3. The top end of the transfer barrel 3 contacts the flat straight surface at the bottom side of the end of the limiting rod 404 to limit the transfer barrel 3, achieving the purpose of pouring the transfer barrel 3 without manual pouring and improving safety.

[0041] Please refer specifically to Figures 1 - 3 There are two fixed blocks 403 and limiting rods 404. The two fixed blocks 403 and limiting rods 404 are symmetrically distributed on the outer wall of the mounting frame 402. A hollow ring for placing the transfer barrel 3 is formed at the inner bottom end of the mounting frame 402. The outer wall at the top end of the limiting rod 404 is of a triangular structure, the inclined end faces of the limiting rod 404 are close to each other, the outer wall of the abutting block 406 is in an arc shape, the positions of the connection points of the limiting rod 404 and the fixed block 403 connected to both ends of the spring 405 are inclined, and the inclination directions of the two springs 405 are in an "eight" shape.

[0042] In this embodiment: With this structure, when it is necessary to take out the transfer barrel 3, the transfer barrel 3 can be manually rotated. The rotating transfer barrel 3 synchronously drives the abutting block 406 on the outer wall to rotate, so that the arc-shaped outer wall of the abutting block 406 contacts the outer wall of the limiting rod 404. The outer wall of the limiting rod 404 is rotationally squeezed by the abutting block 406 and moves outward, so that the flat straight surface at the end of the limiting rod 404 is no longer above the transfer barrel 3. At this time, an upward lifting force can be applied to the transfer barrel 3 to take out the transfer barrel 3, achieving the purpose of automatically releasing the limit of the transfer barrel 3.

[0043] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
