| Abstract: | A cultivator which can achieve the purpose of high straw returning by rotary tillage with double roller was designed. The overall structural design and working principle of the cultivator were introduced. The field tests were conducted in order to examine its operating performance. The results of field tests indicated that the cultivator could realize multiple functions at the same time, such as the high straw mulching and returning, soil crashing, and surface leveling. The working qualities of cultivator which met the agrotechnical requirement of rice sowing and transplanting were as follows: the tillage depth of 158.7 mm,the stability of tillage depth of 84.86%, the straw coverage rate of 94.19%, the surface roughness after rotary tillage of 25 mm, and the productivity of 0.87 hm2/h. |
