Back-loading compression type garbage truck

The utility model relates to the technical field of compression type garbage trucks, in particular to an after-loading compression type garbage truck. A rear filling mechanism of the garbage truck is hinged to the left side of a sealed garbage can, the side, away from the sealed garbage can, of the rear filling mechanism is in a vertical state, the top of the rear filling mechanism is open in the horizontal direction, and the rear filling mechanism is used for collecting garbage and conveying and compressing the garbage into the sealed garbage can; the rear feeding mechanism is hinged to the outer side of the rear filling mechanism and used for lifting a garbage can to the position above the top of the rear filling mechanism, and therefore garbage is dumped from the position above the top of the rear filling mechanism. The follow-up rear door opening and closing mechanism is hinged to the top of the rear filling mechanism and movably connected with the rear feeding mechanism, and the follow-up rear door openi
