The utility model discloses a novel deep scarification and soil preparation combined machine. The novel scarification and soil preparation combined machine comprises a machine frame, a three-point hanging frame connected to the front end of the machine frame, a deep scarification shovel frame, deep scarification shovels, deep scarification shovel fixing elements, a self-excited vibration elastic assembly, a trampling roller, a trampling roller adjustment plate, a trampling roller connecting plate and a soil scraping plate, wherein the deep scarification shovel frame is hinged into lifting lugs under a left edge beam and a right edge beam of the machine frame, and the deep scarification shovel frame and the machine frame are connected through the elastic assembly. The elastic assembly is arranged through an upper tension spring and a lower compressed spring which are located at the front end and an upper compressed spring and a lower tension spring which are located at the rear end, and thus the front portion and the rear portion of the deep scarification shovel frame can vibrate vertically relative to the machine frame. The deep scarification shovels are arranged in a W mode, and the top portions of the deep scarification shovels are in bolted connection with the deep scarification shovel frame through the deep scarification shovel fixing elements. The distances between the deep scarification shovels can be adjusted, the tilling depth can be adjusted, the trampling roller and the soil scraping plate are hinged to the rear end of the machine frame through the trampling roller connecting plate, and height adjustment can be achieved through the trampling roller adjustment plate. The novel scarification and soil preparation combined machine is suitable for deep scarification and soil preparation of farmland and has the advantages that the structure is simple, resistance is reduced, and energy is saved.
