近年来,随着机械化程度在农业生产中不断提高,国外大功率拖拉机被大量引进,机械化采棉也已呈现出发展趋势。由于国外进口的采棉机分4、5、6摘头的不同型号,要求有相应的配套播种机。对于4摘头机,有4膜16行播种机。对于6摘头机,有3膜12行播种机。5摘头采棉机的配套播种机制造难度较大,从拖拉机功率利用率、塑膜利用率、塑膜宽度通用性、机械结构合理配置、运输通过性等方面都存在着难以兼顾的问题。同时,从国外引 In recent years, with the increasing degree of mechanization in agricultural production, foreign high-power tractors have been introduced in large numbers and mechanized cotton pick-up has also shown a trend of development. Due to foreign imports of cotton picker 4,5,6 pick the first of the different models, the required matching sowing machine. For the 4 pick-up machine, there is 4-film 16-row seeder. For a 6 pick-off machine, there is a 3-film 12-row seeder. 5 Pick-picking machine supporting sowing machine manufacturing more difficult, from the tractor power utilization, plastic film utilization, plastic film width versatility, rational allocation of mechanical structure, transportation and other aspects of the existence of difficult problems. At the same time, from abroad
