[0026] When in use, high-temperature tail gas generated by the incineration of garbage is injected into the shell body 1 through the air inlet pipe 12. When the high-temperature tail gas flows from bottom to top in the shell body 1 to the opening of the feeding funnel 2, the garbage in the shell body 1 can be preheated, the heat of the high-temperature tail gas generated by the incineration of garbage can be recovered and utilized, and the temperature of the garbage added to the incinerator can be increased to improve the incineration efficiency.

When the telescopic component 15 pushes the lifting seat 17 upward to move reciprocatingly, the push rod 181 moves reciprocatingly in the perforation 19, thereby reciprocatingly pushing the garbage on the top of the lifting seat 17. When the lifting seat 17 moves close to the rotating seat 13, the air bag 186 is squeezed, the movable side wing 20 is closed, and the air guide pipe 18 The compressed air in the airbag 186 is directed to the push rod 181, and the air in the push rod 181 is ejected through the opening of the air outlet 182.
