[0025] Specifically, the height of the outer bottom surface of the fixing tube 21 is equal to the height of the outer top surface of the mesh box 22 .

[0026] By adopting the above technical solution, the mechanism can ensure that the outer bottom surface of the fixed cylinder 21 can be tightly attached to the outer top surface of the mesh box 22, thereby preventing the solid waste in the fixed cylinder 21 from leaking when it is not needed.

[0027] Specifically, the buffer assembly 25 includes a damper 251 and an elastic rubber frame 252 . The elastic rubber frame 252 is installed between the connecting frame 27 and the bottom plate 1 .

After the feeding channel assembly 6 discharges the crushed material, the receiving box 54 can receive and store it, thereby better meeting the work needs in different situations.

[0036] In the utility model, the structures and principles of a stirring and crushing assembly 4 composed of a processing shell, an opening, a connecting channel, a rotating shaft, an agitator, a rotating motor and a reinforcing support rod, a feeding channel assembly 6 composed of a feeding channel and a pull-out baffle, a pushing assembly 7 composed of a rotating shaft, a pushing plate and a rotating motor, and a lifting column 8 have been disclosed in a solid waste combustion rotary kiln feeding mechanism disclosed in Chinese patent application No. 202322309443.6.
