The invention discloses a rubbish disposal truck, which comprises a truck frame. The truck frame comprises a hollow axle, a rear axle bracket fixed to the rear end of the hollow axle, and a middle axle bracket fixed to the front end of the hollow axle; the hollow axle is arranged in the front-back direction of the truck, a rear wheel axle is fixed to the rear axle bracket, and a rear hub is mounted on the rear wheel axle; a front axle sleeve rotationally sleeves the hollow axle, and a sliding strip is arranged at the rear end of the front axle sleeve; a rear axle sleeve is slidably mounted atthe rear end of the front axle sleeve through the sliding strip, and a hollow inner cavity is formed in the hollow axle; and a first motor and a battery are mounted in the hollow inner cavity, the battery supplies power to the first motor, and the output end of the first motor is connected with a screw. Through innovative structural design of a human-powered driving structure, necessary chains ina traditional bicycle transmission structure are removed, thus the structure is simplified, a variable-speed adjusting structure is arranged in a hollow pipe fitting of the truck frame, and thus the rubbish disposal truck is further structurally simplified and has practicability.
