Embedded planting mode adjustable hole sowing wheel

The invention discloses an adjustable hole sowing wheel in an embedded planting mode. The adjustable hole sowing wheel comprises a mounting frame, a transmission shaft is rotatably mounted on the mounting frame, a seed taking part is fixedly mounted on the mounting frame, a left hole forming wheel is rotatably sleeved outside a seed taking box, an adjuster is slidably sleeved outside a right extension section of the transmission shaft, and a right hole forming wheel is movably sleeved outside the adjuster; each hole forming wheel comprises a fixed wheel and a movable wheel, the right hole forming wheel is driven by the regulator to move left and right along the transmission shaft, so that the right hole forming wheel and the left hole forming wheel are jointed and separated; the adjustor drives the wheel plate units of the right cavitation wheel to stretch out and draw back in the radial direction of the fixed wheel, radial expansion or radial contraction of the movable wheels of the two cavitation wheels is
