The invention discloses soil overturning equipment for agriculture. The equipment comprises a bottom plate, a supporting frame, a transmission shaft, moving wheels, armrests, an engine, a driving wheel, a first belt, a first transmission wheel, a connecting shaft, supporting blocks, a second transmission wheel, a third transmission wheel, a second belt, a fixing frame, a sleeve, a lifting rod, coulters, a fixing block, first connecting blocks, a shaft seat, a screw rod, a hand wheel, a sliding block, second connecting blocks, connecting rods, through holes, a soil flattening mechanism, slidingslots, sliding holes and rubber sleeves; the supporting frame is arranged on one side of the lower end of the bottom plate, the transmission shaft is arranged at the lower end of the supporting frame, and the moving wheels are arranged at the two ends of the transmission shaft respectively. By rotating the hand wheel, the screw rod is driven to rotate, so that the sliding block moves up and downalong the screw rod. Under the action of the connecting rods, the fixing block is pushed to drive the lifting rod to move up and down in the sleeve so that the soil overturning depth of the coulters can be adjusted; moreover, the two coulters can improve the soil overturning efficiency, and the work efficiency is further improved.
