The invention discloses a high-speed pneumatic precision sprouting seed discharging device with oppositely arranged tilting discs. The high-speed pneumatic precision sprouting seed discharging devicecomprises a box body, wherein air chambers are formed in the outer walls of inclined wall surfaces, and seed sucking discs corresponding to the air chambers are arranged on the inner walls of the inclined wall surfaces; seed cleaning sawteeth are arranged above the seed sucking discs, a universal joint transmission device is arranged in the box body and comprises a constant velocity universal joint and a transmission shaft arranged at the end of the constant velocity universal joint, the two ends of the constant velocity universal joint are arranged on the seed sucking discs, and the transmission shaft penetrates through the seed sucking discs and the box wall of the box body and extends out of the air chambers; a transmission chain wheel is arranged at the end of one transmission shaft outside the box body, and a seed blocking partition plate is arranged in the box body portion below each seed sucking disc; seed dropping holes are reserved between the inner walls of the other side wall surfaces of the box body and the seed blocking partition plates. The high-speed pneumatic precision sprouting seed discharging device is simple in structure, long in service life and capable of meeting seed discharging requirements in a high-speed working state, and has the advantages of being high in seed sucking performance, good in seed feeding and discharging stability, good in adaptability,high in operation efficiency, low in seed leakage rate and damage rate and low in energy consumption.
