The invention discloses an automatic mud-shoveling and discharge apparatus, and is characterized in that the automatic mud-shoveling and discharge apparatus includes an upper operation machine frame and a lower machine frame; the automatic mud-shoveling and discharge apparatus also includes a horizontal longitudinal movement mechanism used for making the upper operation machine frame to be in horizontal movement on the lower machine frame; the automatic mud-shoveling and discharge apparatus further includes an upper and lower traction device; the automatic mud-shoveling and discharge apparatus further includes a residue scraper; the residue scraper is connected to a winding wheel through a traction rope, and is suspended below the upper operation machine frame. The automatic mud-shoveling and discharge apparatus effectively improves the clean-shoveling rate, has relatively low equipment damage rate, and increases the production efficiency; and compared with a conventional discharge technology, the automatic mud-shoveling and discharge apparatus allows the equipment damage rate to be obviously reduced, the number of operative employees to be greatly reduced, and manpower, material resources and financial resources to be saved.
