玉米剥皮装置的设计研究

根据农艺过程中对玉米剥皮装置的要求,设计了与4YW-2型玉米联合收获机配套使用的玉米剥皮装置,该部分主要由入料口、剥皮装置、压送装置、输送搅龙及传动装置等部分组成,可以一次作业完成玉米穗的传送、剥皮、玉米与苞叶的分隔收集等作业。为此,以玉米苞叶的剥净率、落籽率、籽粒损失率和生产率为主要指标,计算了部分零部件的结构尺寸。该玉米剥皮装置在4YW-2型玉米联合收获机上配置紧凑协调,作业顺畅可靠,玉米剥皮过程中剥净率达90%以上、作业损失率低于4%,保证了联合收获的作业性能指标,提高了联合收获机的生产效率。

Design of the Corn Peeling Equipment

According to the requirements of corn peeling device in the agronomic process,this paper introduces the design of corn peeling device which supporting the use of 4YW-2 type corn combine harvester, consisted of a material inlet, peeling device, pressure feeding device, conveying auger, transmission device etc. The peeling device can achieve trans-fer, peeling,corn and bract separated collection. This paper takes the husker rate,seed dropping rate,grain loss rate and productivity as the main index,calculated some parts of structure size. The designed peeling device are compact and co-ordinated in the 4YW-2 type corn harvester, operating smooth and reliable. It can also ensure the peeling rate more than ninety percent, grain broken rate less than four percent,performance index of joint harvest and improve the production ef-ficiency of combine harvester.
