Soil crushing and preparation machine

The utility model relates to the technical field of agricultural mechanical equipment, and discloses a soil crushing and preparing machine which comprises a machine frame, connecting frames are arranged on the two side faces of the machine frame, one end of each connecting frame is fixedly connected with a fixing cover, and the inner wall of each fixing cover is in transmission connection with a transverse rolling shaft. The ploughing device has the advantages that the driving assembly drives the transverse rolling shaft on the inner side of the fixing cover to drive the crushing teeth on the outer surface to rotate, hard soil blocks in soil are stirred and crushed at the same time, so that the soil blocks are in a uniform size state, and due to the fact that the ploughing teeth are located behind, after the front soil is crushed, the soil blocks can be effectively ploughed. And the rear side drives a transmission gear to rotate through a transmission chain, so that a hole transmission shaft and ploughing tee
