[0027] The crushing chamber 34 of the present application performs preliminary crushing of large pieces of waste mainly by meshing of a plurality of teeth arranged on the surfaces of the first rolling roller 342 and the second rolling roller 343. The feed port 30 and the meshing part are on the same axis, so that the waste can directly enter the meshing part through the feed port 30 for preliminary crushing. The first rolling roller 342 and the second rolling roller 343 are mainly provided with a first support shaft 340 and a second support shaft 341 arranged inside the crushing chamber 34 to provide a rotational force for them to rotate respectively, so as to mesh and crush the waste. The connection of the first support shaft 340 and the second support shaft 341 in the crushing chamber 34 is a prior art and will not be described in detail here.
[0028] In some preferred embodiments, the stirring assembly 4 includes a rotating rod 41 connected to a driving motor 40, and a first stirring rod 42 and a second stirring rod 43 are arranged on the periphery of the rotating rod 41, and the second stirring rod 43 is longer than the first stirring rod 42.
