The invention relates to a wheel type rice wide-narrow-line direct seeding fertilization combined
machine, which belongs to
agriculture machinery. Shallow and deep fertilization double-disc furrow opening devices, a
fertilizer box, a
paddy field driving wheel axle and a seed box are sequentially arranged on a
machine frame from the front side to the back side, a driving double-chain wheel, the
paddy field driving wheel and a compression roller are fixedly arranged on the
paddy field driving wheel axle, the
fertilizer box is respectively communicated with the shallow and deep fertilization double-disc furrow opening devices through shallow and deep fertilization pipes, a
fertilizer discharge driving chain is sheathed on the driving double-chain wheel and a fertilizer
discharge wheel arranged on a fertilizer
discharge device shaft, a seed discharge driving chain is sheathed on the driving double-chain wheel and a seed discharge chain wheel arranged on a seed discharge device shaft, and a seed discharge and seed conveying
pipe is arranged on the lower side part of the seed box. The wheel type rice wide-narrow-line direct seeding fertilization combined
machine has the advantages that the design is novel and reasonable, the structure is simple, the traction resistance is small, the operation items are many, the operation quality is good, the fault is few, the efficiency is high, and the synchronous combined operation of the rice direct seeding and fertilization and the wide-narrow line fertilization operation depth regulation can be realized.
