【Abstract】 This article introduced the performance and traits of Nongtian 1GZ-2, analysed the main parameter of ths parts of sugar beet digging and seeding unit especially, and stated the relation between the effect area of soil stress or digging resistance and digging aad loosing angle of entering. Through calculating the height(H) of pips of seed division, relative install angle(a), and the best parameters were found out. All quota reached the requirement of designs of machine in sugar beet seeding and digging.更多还原
