[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] Example:

[0028] like Figures 1-4 As shown, a charcoal-burning furnace body includes an inner furnace body 10, an outer furnace body 20, a support plate 30, and a lifting mechanism; the outer furnace body 20 has a combustion chamber inside; the inner furnace body 10 is located at the top of the combustion chamber inside the outer furnace body 20, and the bottom of the inner furnace body 10 has a combustion port 11 communicating with the combustion chamber; the inner furnace body 10 has a combustion chamber with its top communicating with the outside; during charcoal burning, the tops of the inner furnace body 10 and the outer furnace body 20 are covered with a furnace cover to achieve closure; a ring-shaped step is provided circumferentially on the inner side of the combustion port 11 at the bottom of the inner furnace body 10, and the support plate 30 is mounted on the top of the step at the combustion port 11 of the inner furnace body 10. The support plate 30 has a connecting part, which may include a column 31 and a hanging ring 32. The column 31 is vertically located in the middle of the top of the support plate 30, and the hanging ring 32 is located at the top of the column 31.

[0029] The lifting mechanism includes a hydraulic rod 40 and an extension frame 50. The hydraulic rod 40 is located on one side of the outer furnace body 20. The bottom of the extension frame 50 is connected to the top of the hydraulic rod 40. The free end of the top of the extension frame 50 extends horizontally to the center of the inner furnace body 10. A connecting ring is provided on the bottom side of this end. The connecting ring is connected to a hook 51 through a ring. The hook 51 can be connected to the hanging ring 32. The top of the hydraulic rod 40 is provided with a cylindrical connector 41. The end of the extension frame 50 connected to the hydraulic rod 40 is provided with a connecting groove that matches the connector 41. A screw hole 42 is opened on the side wall of the connector 41. The side wall of the connecting groove is provided with a through hole 52 that aligns with the screw hole 42. A bolt that matches the screw hole 42 passes through the through hole 52.

[0030] The working principle of the above technical solution is as follows:

[0031] In use, wood is placed on the support plate 30 for charcoal burning. The support plate 30 is set up at the combustion port 11. After the charcoal is burned, the furnace cover is opened, and the extension frame 50 is rotated around the hydraulic rod 40 to be directly above the inner furnace body 10. The bolts are tightened to lock the orientation of the extension frame 50 relative to the hydraulic rod 40. The hydraulic rod 40 is lowered, and the hook 51 is connected to the hanging ring 32. By raising the hydraulic rod 40, the support plate 30 can be lifted to the top of the inner furnace body 10, and the extension frame 50 is rotated to a position where it is convenient to remove the charcoal, so that the staff can quickly remove the charcoal from the support plate 30 using tools.

[0032] In another embodiment, such as Figure 1 As shown, the top edge of the combustion chamber of the inner furnace body 10 is provided with a first partition ring 61, a second partition ring 62 and a third partition ring 63 from the inside to the outside; a groove for placing the furnace cover is formed between the first partition ring 61 and the second partition ring 62, and a soil filling groove is formed between the second partition ring 62 and the third partition ring 63.

[0033] The edge of the furnace cover can be embedded in the placement groove for installation, and clay can be filled into the filling groove to keep the furnace body sealed.

[0034] In another embodiment, such as Figure 1-2 As shown, the top of the support plate 30 is provided with several support ribs 33 at intervals.

[0035] The support rib 33 facilitates the support of the wood and leaves space for heat circulation at the bottom of the wood, resulting in more even heating.

[0036] In another embodiment, such as Figure 3 As shown, the support plate 30 has a retaining edge around its perimeter, and the height of the retaining edge is higher than that of the support rib 33. The retaining edge includes a fixed edge 34 and a movable edge 35 that form a ring. The fixed edge 34 is C-shaped with an opening on one side, and one end of the movable edge 35 is hinged to the opening of the fixed edge 34.

[0037] The edge of the support plate 30 can prevent the charcoal from rolling off when the support plate 30 is raised and lowered. When the support plate 30 is raised to the top of the inner furnace body 10, the movable edge 35 loses its main support on the inner wall of the inner furnace body 10 and can rotate relative to the fixed edge 34 to open the opening of the fixed edge 34, from which the charcoal can be taken out.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
