The invention discloses a dust smoke removal device for a round baler. The dust smoke removal device comprises a baling tank, a seal chamber, baling rollers, a dust-collection filter tank, a dedustingbox, a dust guide pipe, a water pump, a water tank, a water guide pipe, a sewage pipe, a motor, a dust suction head, fan blades, a rotating shaft, a partition plate, a clear water chamber, a sewage chamber, a filter screen, spraying pipes, spraying heads, a layering plate and an exhaust pipe. The seal chamber is connectedly mounted on one side of the baling tank, the baling rollers are mounted inthe baling tank and the seal chamber, and the dust-collection filter tank is mounted on one side, away from the seal chamber, of the inner wall of the baling tank. The motor is mounted in the dust-collection filter tank. The dust smoke removal device for the round baler has advantages that dust in the baling tank is sucked into the dedusting box through the fan blades, dedusting is realized through clear water spraying, structural simplicity and great dedusting effects are realized, and a baling operating environment is improved; dedusting water is filtered and recycled, so that water resources can be saved; due to gathering of dust sediment, convenience in clearing is achieved.
