摘要

In two crops a year region of northern China, no-tillage seeding and subsoiling arecompleted solely, which causes the problems such as more tasks, compacting the soil, increment ofpower consumption, speeding the growth of no-tillage maize. Aiming at above problems andcombining with actual instance of two crops a year region of northern China, this paper advancesdesign scheme of drilling and subsoiling combined machine for no-tillage maize which can be used intwo crops a year region of northern China. The combined machine can once complete all field worksof pushing aside the stalk, ditching, fertilizing, seeding, covering the soil, squashing the soil andsubsoiling, solving the problems which are caused by sole operation of no-tillage and subsoiling,accelerating the growth of maize.The paper advanced design scheme of subsoiling structure and detailedly introduces no-tillageseeding structure of the c ombine machine. Field results show that all the key parts' structures arereasonable, the overall bearing force and power distribution of the machine meet the design need.A series of contrastive tests between combine and sole operation of drilling and subsoiling are set up.Field tests make out that the combine operation of drilling and subsoiling is feasible technically,through using different loosen soil shovels, the combine machine can meet varied demands ofsubsoiling.
