At the same time, during the combustion, with the cooperation of the cross frame 312, the hinged cover 313 and the sealing strip 314, the internal combustion gas will not escape to the outside through the feed port in a large area, ensuring good combustion inside. When the hinged cover 313 is opened, the hinged cover 313 and the feed hopper 311 form an inlet for receiving the garbage, and the rotation of the rotating shaft 315 drives the auger plate 316 to rotate synchronously.

At this time, under the action of the meshing connection between the worm 325 and the worm wheel 326, the rotating shaft 315 is driven to rotate synchronously.

[0027] When the utility model is in use, the fan 2 is driven to inject external gas into the interior of the incinerator body 1 through the air injection pipe 321, and the air flow then passes through the circular cavity 322 to drive the pneumatic blade 324 to rotate, and the pneumatic blade 324 drives the rotating rod 323 to follow the synchronous rotation, and the worm 325 fixedly connected to its surface follows the rotation, and under the action of the meshing connection between the worm 325 and the worm wheel 326, the rotating shaft 315 rotates synchronously, and then the auger plate 316 follows the synchronous rotation to transport the garbage inside the feed hopper 311, and the hinged cover 313 is closed with the cooperation of the cross frame 312 and the sealing strip 314.
