Ploughing device with depth convenient to adjust

The utility model relates to the technical field of ploughing devices, in particular to a ploughing device convenient for depth adjustment, which comprises a ploughing device, a ploughing motor is mounted on one side of the ploughing device, a ploughing shaft is mounted on the ploughing motor, a plurality of ploughing cutters are fixedly arranged on the ploughing shaft, a convex frame is welded at the upper end of the ploughing device, and a plurality of ploughing blades are fixedly arranged on the convex frame. Guide connecting holes are symmetrically formed in the two sides of the convex frame, inclined plane holes are formed in the convex frame, a connecting frame is installed on a power device, then when the ploughing depth needs to be adjusted, a motor is driven to rotate, and therefore a threaded connecting sleeve can be driven to move under the action of threads; and then the ploughing device is driven to move along the inclined plane supporting block, so that the distance between the ploughing device
