The garbage crushed by the crushing knives 27 falls downward. The shredding knife 30 rotates and performs secondary shredding work on the garbage crushed by the crushing knives 27;

[0067] After the garbage that has been preliminarily broken by the crushing knife 27 and the shredding knife 30 falls onto the top wall of the filter plate 15, the liquid in the garbage passes through the filtration of the filter plate 15 and flows downward onto the bottom wall of the crushing chamber 12. The liquid flows out of the crushing housing 11 through the liquid outlet pipe 14 to complete the solid-liquid separation; the vibrator 34 is started, and the vibrator 34 drives the filter plate 15 to vibrate and makes the garbage on the filter plate 15 slide along the inclined direction of the filter plate 15, and the garbage slides into the conveying pipe 16; the conveying motor 17 is started, the output rotating shaft of the conveying motor 17 drives the spiral conveying blade 18 to rotate, the spiral conveying blade 18 rotates and conveys the garbage that enters the conveying pipe 16 upward to the upper part of the conveying pipe 16, the garbage moves upward along the conveying pipe 16, the garbage is conveyed by the spiral conveying blade 18 to the upper part of the opening of the crushing chamber 12, and after the garbage slides out of the pipe orifice of the conveying pipe 16, it is broken again by the crushing knife 27 and the shredding knife 30, so that the garbage undergoes multiple crushing operations, avoiding incomplete crushing of the garbage and being inconvenient for subsequent secondary treatment of the garbage.

[0068] When the garbage has completed multiple crushing operations, the worker opens the switch door 13 and takes out the garbage that has been crushed multiple times from the position of the switch door 13.
