The invention relates to a novel bunch planting drill barrow adopting the mode of 'top discharge' seeding to ensure that embryo of peanut seeds does not suffer from loss during the process of seeding; the mode of 'walking' advance is adopted to greatly decrease the traction force, thereby being convenient for artificial seeding; and the photoelectric detection technology is adopted to eliminate missed seeding. The drill barrow can conveniently adjust steps to meet the requirements of row spacing of different crops, thereby being capable of seeding crops with different row spacing and being a useful tool for peasants. The farm tool has reasonable design and simple structure and is convenient for industrial production.
