Wheat seeding device and method capable of adjusting seeding depth

The invention discloses a wheat seeding device and method capable of adjusting seeding depth, and particularly relates to the field of wheat seeding, the wheat seeding device comprises a support frame, two ends of the support frame are rotatably connected with rotating wheel assemblies, the rotating wheel assemblies are driven by an internal motor to rotate, one end of each rotating wheel assembly is fixedly connected with a half-gear carrier, and when the rotating wheel assemblies rotate, the half-gear carrier is driven by the rotating wheel assemblies to rotate. The rotating wheel assembly drives the half gear frame to rotate synchronously, the radius of the rotating wheel assembly is larger than that of the half gear frame, and built-in transmission lines guide a hollow threaded block and a third rotating rod to move forwards towards the extending part of a telescopic rod, namely, a soil warping plate moves forwards, so that the soil cutting depth is adjusted; a hollow threaded block and a third rotating r
