T he device can finish the precision seed ing of carrot s’ single seed, and one operation plete eight row s and two ridge s cultivation at the same time .A nd it can realize the automatic ridging according to our country existing planting mode. The planter is driven by the 95- horsepower tractor, and its main working parts contain the transmission system , the running system, the ditching device, a ridging device, a precision seed-metering device and the parameter adjusting device. T he ponent oft he machine is the suction seed metering device . It uses the air suction so that it can sow carrot precise ly and reduce the cost of the seeds and the subsequent agricultural operation. The machine operating parameters for the its working speed is .The quality of seeding reaches 97% and the es to 2 /h.
