新型联合整地机的设计与实现

Experimental Research on A New Combined Soil Preparation Machine

[目的]研制1LZ系列新型联合整地机。[方法]针对大功率拖拉机在生产上的应用情况,研制了一种与之配套使用的1LZ系列联合整地机。介绍了整机结构及其工作原理,对联合整地机主要工作部件(平地部件和表土加工部件)进行了研究与设计,并通过了一系列的测试试验和实际生产考核。[结果]1LZ型系列联合整地机采用多种部件联合作业,减少了作业遍数及拖拉机的进地次数,减少了对土壤的有害压实,比国内现有的整地机械提高工作效率30%以上;该整地机作业质量好,能形成地表平整、土壤细碎、上虚下实的良好种床结构,为铺膜播种、精准播种、种子的出苗及作物的生长创造了良好的土壤环境。[结论]实际生产考核证明,该联合整地机能够适应新疆干旱地区农田整地作业。

[Objective] The study aimed to develop the 1LZ series of new combined soil preparation machine.[Method] In order to solve the high-power tractors for the application in production,a kind of 1LZ series combined soil preparation machine that could had auxiliary use with the tractor was developed out.The whole structure and working principle were introduced,the main working parts of the combined soil-working machine inluding the flat ground part and surface processing part were studied and designed and a series of test trials and assessment of actual production were passed.[Result] 1LZ series combined soil preparation machine could use the many kinds of components for joint work,reduce the working times and the times of the tractor coming into the ground and also reduce the harmful compactionon on the soil by the tractor,which could improve work efficiency by 30% compared with the domestic existing soil preparation machinery.The soil preparation machine was good in the operating quality,it could form the good seed-planting bed structure with the flattening soil surface and fine disintegrated soil,which could create a good soil environment for filming seeding,precision seeding,seed seedling and crop growth.[Conclusion] The assessment of the actual production proved that the machine could be adapted to the agricultural land preparation operations in the arid regions of Xinjiang.
