The invention relates to a spraying machine. The spraying machine comprises a cab, a cab lifting device, a variable-tread assembly, a chassis power system, a spraying frame lifting device, a spraying rod assembly, a pesticide box assembly, a wheel assembly and a whole machine hydraulic system, wherein the cab lifting device comprises upper cab parallel rods, cab lifting cylinders, transverse cab stabilizing rods, a fixed cab lifting frame, lower cab parallel rods and a movable cab lifting frame; the upper cab parallel rods and the lower cab parallel rods are equal in length, one end of each parallel rod is hinged to the fixed cab lifting frame, and the other end of each parallel rod is hinged to the movable cab lifting frame; one end of each cab lifting cylinder is hinged to the corresponding upper cab parallel rod, the other end is hinged to the fixed cab lifting frame, and a cab is lifted and lowered under the telescopic action of the cylinders. The spraying machine adopts a hydraulic self-propelling manner, the tread can be adjusted to adapt to ridging spaces of different crops, large-area pesticide application can be performed, the height of a spraying rod can be adjusted according to crop height change, and flexible steering is realized.
