Solid waste feeding and pyrolysis pretreatment device

The utility model discloses a solid waste feeding and pyrolysis pretreatment device which comprises a discharging frame, a feeding assembly is installed in an inner cavity of the discharging frame, a pyrolysis assembly is installed on the right side of the discharging frame, and a feeding hopper is installed on the top wall of the discharging frame. According to the solid waste feeding and pyrolysis pretreatment device, a roller shaft of a cutting roller is driven by a driving motor to rotate, so that the cutting roller and a cutting blade rotate, collected solid waste is put into a discharging frame from a feeding hopper, and then the solid waste falls into a discharging hopper and a discharging pipe after being cut and crushed and is discharged through a discharging cover; and when the cut waste materials slide out of the discharging cover and enter the connecting cylinder on the left side, the solid waste materials are cut and smashed in the feeding process, the whole solid waste materials can smoothly fal
