The shape and size of the cross section of the connecting position of the soil breaking hoe and the shaft rod are larger than those of the cross section of the arc-shaped hoe handle, the mode that the soil breaking hoe is installed on the arc-shaped hoe handle is adopted, the contact face of the deep ploughing rotary hoe and the land is increased during soil loosening, and therefore the deep ploughing rotary hoe can be prevented from loosening soil in the process that the deep ploughing rotary hoe rotates at the top speed under the action of a cultivator. According to the deep ploughing rotary hoe, soil blocks can be rapidly smashed, and the problems that soil blocks loosened through an existing deep ploughing rotary hoe are large, the ploughed soil blocks are hard, and the existing deep ploughing rotary hoe is not suitable for immediately planting crops are solved.
