卧式青核桃脱皮机关键部件优化与试验

通过分析卧式青核桃脱皮机整机及关键部件的结构与工作原理,选择不同结构类型的板刷、刀片以及不同的刀片排列方式进行脱皮试验。确定卧式青核桃脱皮机的关键部件为:c型板刷、f型刀片及h型刀片排列方式,其运行参数为:主轴转速25~35 r/min,喂入量1000~3000 kg/h。当喂入量为2000 kg/h,主轴转速为30 r/min,脱皮间隙为35 mm,脱皮角度为2°时,新新2青核桃脱净率为92.12%,破损果率为4.28%,温185青核桃脱净率为90.32%,破损果率为6.17%,扎343青核桃脱净率为94.69%,破损果率为4.77%。

Optimization and experiment of key components of horizontal green walnut peeling machine

In order to optimize the structure and movement parameters of the key parts of horizontal walnut peeling machine,a kind of horizontal green walnut peeling machine was designed in this paper.By analyzing the structure and working principle of the whole machine and its key parts,the peeling test was carried out by selecting different brush types,blade types and blade arrangement.The key parts of horizontal green walnut peeling machine were determined:C type brush,F type blade and h type blade arrangement.Through the peeling test of spindle speed and feeding amount,the operating parameters of horizontal green walnut peeling machine were determined:spindle speed 25~35 r/min,feeding amount 1000~3000 kg/h.Results:the cleaning rate was 92.12%,the damaged fruit rate was 4.28%of Xinxin 2 green walnut,the cleaning rate was 90.32%,the damaged fruit rate was 6.17%of Wen 185 green walnut,and the cleaning rate was 94.69%,the damaged fruit rate was 4.77%of Zha 343 green walnut under the conditions of the feeding amount of 2000 kg/h,the spindle speed of 30 r/min,the peeling gap of 35 mm and the peeling angle of 2°.
