The invention discloses a spin milling type multifunctional machine for deeply ploughing and crushing ridges, which is based on a tractor. A hydraulic mechanism and a linking spin milling drill bit device or a cultivation component is arranged on a rear frame of the tractor; the linking spin milling drill bit device is provided with one or more drill bit shafts; spiral hinges are arranged on the drill bit shafts and provided with apical teeth; the linking spin milling drill bit device is provided with a device for preventing a straw from being wound; the hydraulic mechanism drives a spin milling drill bit to move up and down; and a gearbox drives the spin milling drill bit by a connecting rod and a gear. According to the spin milling type multifunctional machine, the drill bit enters into soil and then vertically cuts, spin mills and crushes the soil and ensures that the soil is automatically suspended to form the ridges; the soil crushing section of the crushed ridge is T-shaped; the lower part of the compacted soil on the ground is in a U-shaped groove, so that the whole layer of the soil is in a loosing state during cultivation; and in addition, the invention plays roles of covering and replacing the soil, increases an active layer, improves the capabilities of preserving moisture and fertility and the permeability of the soil, benefits the utilization of deep growing of the crop root system to water and fertilizer, relatively reduces pests and weeds and ensures that the crop is easy to obtain high and stable yield.
