摘  要：
针对油菜联合收获机械对油菜成熟度要求高、适收期短、收获损失率大、作业能耗高等问题,设计了一种适应于南方小田块油菜分段收获的4SY-1.8型手扶式油菜割晒机,进行了油菜的切割、分禾、铺放与挂接等装置的结构设计与分析。田间试验表明:设计的油菜割晒机能有效完成中间分禾、两侧条铺的割晒作业;割晒油菜的铺放角度平均值为36.4°,在45°以下概率为75.8%;割茬高度平均值为278.2 mm,在230~330 mm以内的概率为85.2%;铺放宽度平均值为1 027.6 mm,在1 150 mm以下的概率为81.1%;作业质量满足后熟晾晒和机械化捡拾收获农机农艺要求。

摘  要：
In order to take advantage of the characteristics of growth and maturity of rape,overcome the disadvantage of high loss ratio and power consumptive of rape combine harvester,4SY-1. 8 type rape windrower was investigated. The novel windrower was designed for matching to walking tractor to meet both agro-mechanization and rape planting actuality in southern China. The design and construction characteristics of cutting,dividing,laying and hitching unit and considerations in the migration of rape stalks were analyzed. The results of field experiment showed that the windrower could complete the work of middle dividing and laying on both sides efficiently. The mean laying angle of rape stalk was 36. 4°,which was less than 45° with 75. 8% probability. The mean width of the piled stalk was 1 072. 6 mm,which was less than 1 150 mm with 81. 1% probability. The mean of stubble height was 278. 2 mm,which was between 230 mm and 330 mm with 85. 2% probability. The test results indicated that it had a rational design and reliable function and its working quality can be easily met the agricultural requirement.
