SGTN-180型旋耕埋草施肥联合作业机的设计与试验
Design and experiment of a SGTN-180 type rotary tillage-straw returning-fertilization combined machine
摘要
Abstract
In order to improve the working performance and reduce the power consumption,a combine machine SGTN- 180 is designed. The structure design and working characteristics of the combine machine are introduced. The configuration of the double roller position and the design of the power transfer system were mainly analyzed. This combined machine works with a special working pattern that has a front roller forward rolling and a rear roller reversing rolling. The front roller chops the straw and sends the crushed straw to the rear roller. The rear roller breaks the soil and returns the straw-soil mixture to the ground. The experimental results indicate that the combined straw returning-rotary tillage-fertilization machine has a fine working quality, which is characterized by the quality indexes as follows: vegetation coverage 94.8％, soil broken rate 93.1％, surface smoothness after working 0.4 cm, stability coefficient of tillage depth 97.2％ ,and a banding distribution of fertilizer mixed with soil in depth of 2- 11 cm.关键词
