一般的扬场机在作业中受多种条件限制,是不宜移动的。当扬场机升运器附近的谷物被喂完之后,只能移动谷物向扬场机靠拢,劳动紧张而繁重。另外,一般扬场机只有一个电动机,同时带动环形胶带和升运器,所以扬射谷物的高度与距离,受工作负荷影响很大。由于人工喂入的谷物量不可能很均匀,即使风向,风力不变,谷物抛落的位置也是不固定的,这就使得不同质量的谷物和杂质在空中分离后,落地又重新混杂在一起,不得不反复扬场多次。为了克服一般扬场机的上述缺点,我们对其进行了改制。现以YC-10型扬场机为例加以说明。
General Yang machines in a job by a variety of conditions, it is not appropriate to move. When the cereal in the vicinity of the hoisting machine is fed, the grain can only be moved closer to the hoisting machine, causing labor stress and heavy labor. In addition, the common vertical machine only one motor, while bringing the loop tape and the elevator, so the height of the grain and distance from Yang, by the workload of a great influence. As the amount of artificial feed grain can not be uniform, even if the wind direction, the wind unchanged, the location of grain falling is not fixed, which makes different quality of grain and impurities in the air after the separation, landing and re-mixed together, Have repeatedly repeatedly Yang. In order to overcome the above-mentioned shortcomings of the common machine, we have carried on the reform to it. YC-10 is now Yixing Ji as an example to illustrate.
