The utility model discloses a corn precision dibbling pneumatic type centralized seed supply device which comprises a box body, a plurality of seed metering mechanisms and a plurality of air blowing mechanisms, each seed metering mechanism comprises a hopper and a seed metering device, and an inlet of the seed metering device is communicated with an outlet of the corresponding hopper; each air blowing mechanism comprises a three-way
pipe and an
air blower, a first interface of the three-way
pipe is communicated with an outlet of the corresponding seed metering device, a second interface of the three-way
pipe is communicated with an outlet of the
air blower, and a third interface of the three-way pipe is communicated with a seed inlet of the corresponding seeding unit through a connecting hose. The seed
sowing device has the beneficial effects that the air blowing mechanism is arranged, so that seeds discharged by the seed
sowing devices can be fed into the seed inlets of the seed
sowing single bodies through the connecting hoses, and as the connecting hoses can be freely bent, the seed sowing devices do not need to be arranged right above the seed sowing single bodies, so that a plurality of seed sowing devices can be intensively arranged together; therefore, the
mass and the size of the seeding device are effectively reduced, transportation and storage are convenient, transmission is simple, and efficiency is high.
