Dry land corn moisture supplementing and soil preparation machine

The invention discloses a dry land corn moisture supplementing and soil preparation machine, and mainly aims to solve the problems that time and labor are wasted and production efficiency is low due to the fact that supplementing irrigation and soil preparation are carried out separately before dry land corn sowing. The dry land corn moisture supplementing and soil preparation machine comprises a supporting frame, a box body is fixedly installed in the supporting frame, an instrument box and a water storage box are arranged in the box body, a soil moisture meter and a water pump are installed in the instrument box, a rotating rod is rotationally installed in the supporting frame, a soil turning plate is obliquely installed on the side wall of a rotating wheel disc, an installation groove is formed in the side wall of the supporting frame, a rotating frame is arranged in the installation groove, a soil loosening block is installed outside the rotating frame, and a water outlet pipe is connected between two sup
