[0029] Among them, the stirring mechanism is arranged in the box body 1 and is used to stir the materials on the support plate 3, so that the fixed fuel burns more fully, avoids accumulation, and improves the combustion efficiency;

[0030] like Figure 2-4As shown, the stirring mechanism includes a connecting rod 13 rotatably mounted on the support plate 3, one end of the connecting rod 13 passing through the support plate 3 is fixedly mounted with a reciprocating screw 16, one end of the reciprocating screw 16 is fixedly mounted with a rotating shaft 4, a short rod 19 is fixedly mounted on the connecting rod 13, a plurality of mounting blocks 21 arranged at equal distances are fixedly mounted on one side of the short rod 19, a stirring block 28 is slidably mounted on one end of the mounting block 21 for stirring the fixed fuel on the support plate 3, the stirring block 28 is in contact with the support plate 3, a first pulley 5 is fixedly mounted on one end of the rotating shaft 4, a motor 15 is fixedly mounted in the box body 1, and the motor 15 The output shaft is fixedly mounted with a second pulley 14, a belt 6 is sleeved between the first pulley 5 and the second pulley 14, when the motor 15 is started, the output shaft of the motor 15 drives the second pulley 14 to rotate, the second pulley 14 drives the first pulley 5 to rotate through the belt 6, the first pulley 5 drives the connecting rod 13 to rotate, so that the stirring block 28 installed on the connecting rod 13 stirs the solid fuel on the surface of the support plate 3 to make it burn fully and avoid fuel accumulation, and a dredging mechanism is provided in the box body 1 to prevent the ash hole 22 from being blocked, so that the ash can be discharged quickly, which is beneficial to improving the combustion efficiency.

[0031] like Figure 2-4 As shown, the dredging mechanism includes a sliding plate 25 rotatably mounted on the reciprocating screw rod 16, and the sliding plate 25 and the supporting plate 3 are both V-shaped, so that the sliding plate 25 can completely fit the supporting plate 3, and the ash falling on the sliding plate 25 can slide down along the sliding plate 25, and the sliding plate 25 is located below the supporting plate 3, and a plurality of through holes 20 arranged at equal distances are opened on the sliding plate 25, and a plurality of cone blocks 24 arranged at equal distances are fixedly mounted on the sliding plate 25, and the height of the cone blocks 24 is equal to the height of the ash falling holes 22 to avoid contact with the stirring blocks 28, and a guide column 7 is fixedly mounted in the box body 1, and the guide column 7 is slidably connected to the sliding plate 25, and when the motor 15 rotates, the reciprocating screw rod 16 is driven to rotate, and since the reciprocating screw rod 16 is rotatably connected to the sliding plate 25, the sliding plate 25 makes an up and down reciprocating motion on the reciprocating screw rod 16, and when the sliding plate 25 contacts the supporting plate 3, the cone blocks 24 dredge the ash falling holes 22 to avoid blockage of the ash falling holes 22.

[0032] A slide groove 2 is provided on the inner wall of the box body 1, and fixed blocks 23 are fixedly installed on both sides of the support plate 3.
