Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a double-cavity seed box for a dual-purpose precision seeder for field seed production. Background technique [0002] At present, the sowing operation of corn and other upland crops mostly adopts multi-row air-suction precision seeders pulled by tractors. The main structure of this kind of seeder is: There are fertilizer boxes, seed boxes and ground wheels. Wherein, a seed metering device is provided under the seed box, and the seed metering device is provided with a suction cup with a suction hole. One side of the suction cup is adjacent to the seeds in the seed cup, and the other side is adjacent to the negative pressure chamber. When the ground wheel rotates, the chain drives the suction cup to rotate, and the suction hole opposite to the negative pressure chamber absorbs the seeds to run, and the seeds are dropped when the suction hole breaks away from the negat...
