The inner tooth is composed of multiple sets of arc-shaped toothed plates (16), and a gap (41) is formed between adjacent arc-shaped toothed plates (16). A sliding plate (20) is provided on the outer wall of the arc-shaped toothed plate (16). The end of the slide plate (20) away from the arc toothed plate (16) passes through the outer wall of the ring plate (402) and forms a sliding connection with the ring plate (402). The inner wall of the drive ring (91) is provided with an initial groove (21) for one end of the slide plate (20) to be inserted. The side wall of the initial groove (21) is provided with an inclined surface (22). Rotating the drive ring (91) causes the inclined surface (22) to abut against the slide plate (20) and drive the arc toothed plate (16) to slide towards the inner toothed plate (18) to form a mesh.

3. The smelting furnace with rapid feeding according to claim 1, characterized in that: The outer card plate (11) is provided with an outer groove (39) for the outer toothed plate (17) to slide, and the base ring (10) is provided with a groove (37) for the connecting ring (19) to slide. The groove (37) is composed of an outer semi-circular groove (372) and an inner semi-circular groove (371).

4. The smelting furnace with rapid feeding according to claim 1, characterized in that: A lever (92) is provided on the outer wall of the drive ring (91).

5. A rapid feeding smelting furnace according to claim 1, characterized in that: The bottom of the discharge pipe fitting (23) is sealed, and the lower end of the outer circumference of the discharge pipe fitting (23) is provided with a discharge port (24). The bottom end of the discharge pipe fitting (23) is inclined.

6. A rapid feeding smelting furnace according to claim 5, characterized in that: The drive assembly (29) includes a motor (291) and a drive disk (292). The outer peripheral wall of the drive disk (292) is provided with partial teeth (30), and the outer wall of the drive sleeve (27) is provided with annular teeth (31) that mesh with the partial teeth (30).

7. A rapid feeding smelting furnace according to claim 1, characterized in that: The bottom end of the positioning tube (5) is fixed with an expansion tube (8), and the end of the second telescopic tube (7) away from the smelting furnace is fixedly connected to the expansion tube (8).
