The invention relates to the field of agricultural equipment, in particular to a straw throwing and burying combined machine. The combined machine comprises a burying device (1), a hanging device (3),a throwing device (9) and a power transmission device (12). A vertical rotation mode is adopted by the throwing device (9) of the combined machine according to a tedding machine principle, and underthe action of centrifugal force, straw is thrown to the two sides; air flow is formed between adjacent throwing mechanisms (14), so that the straw throwing range is further expanded. When the combinedmachine goes to the field once, straw throwing work and straw burying work can be completed at the same time; meanwhile, the burying device (1) at the rear end of the combined machine can be removedso that separate straw throwing operation can be achieved, and moreover, combined operation of the throwing device (9) and a land preparation machine without power drive, such as a disc plough and a disc harrow, can be achieved through adjustment, the number of times for the machine to go to the field is reduced, and the energy consumption is reduced.
