TS160型桑叶甩干机的研制

针对市场上的桑叶甩干机台时产量低 ,造价偏高等缺陷 ,采用增加装叶量 ,提高叶篓转速 ,设置手刹装置和甩块式快慢速转化器等改进设计 ,制造出新型桑叶甩干机。桑叶甩干机集水桶直径 16 0 0mm ,桶内 3个叶篓框直径 5 0 0mm ,一次装满流水状桑叶 12 0kg ,以 5 5 0r/min速度转动 ,在 3～ 4min内 ,桑叶甩干程度为 88 89% ;叶篓框主轴与动力输入三角带轮 ,采用甩块活式连接 ,转速由慢变快 ,既有保护电机的作用 ,又比同类快慢速转换器降低造价 2 0 %以上 ;全机用 3个大弹簧对应 3足机架装配 ,甩干作业时 ,震动小 ;手刹装置 ,在 3～ 5s内 ,把惯性旋转中的叶篓框止动 ,提高了单位时间内的生产率。

Development of the Model TS160 Spin-drier for Mulberry Leaves

In accordance with the weakness of current spin drier of mulberry leaf in lower yield and higher price, we improved the design and made out a new model spin drier of mulberry leaf by increaseing mulberry leaves’ loading amount,raising revolving speed, installing an equipment of hand brake and using speed switching device.The diameter of the water pail in spin drier is 1 600 mm. Each of three mulberry leaf basket brackets in the pail is 500 mm in diameter,120 kg water flowing leaves can be loaded every time, the machine runs at a speed of 550 r/min. The degree of spin dry reached 88 89% within 3 or 4 minutes. The power take off wheel drives the principal axis of basket brackets by centrifugal and friction bar, which can not only protect electric motor, but also reduce the cost by above 20% compared with the same kind of snubbers. The whole machine has three foots assembled with three spring coils, which makes vibration very slight.It can stop the revolving basket brackets within 3-5 seconds with a hand brake, which raised the productivity per unit time.
