激光技术能防止采盐机刀片损坏盐结晶池池底,从而节省采盐时间和经费。将位于固定勘测点上的旋转激光束发射到采盐机刀片的接收器上,接收器再发送信号给采盐机驾驶室,指示刀片是高于还是低于或正好处于正确切割水平线上。为了高效率采盐并防止在专门准备的盐结晶池基面凿出沟槽,精确切割很重要。这点以前是靠机器操纵手来判断的。 Laser technology prevents the saltwater blade from damaging the salt cell pool bottom, saving time and money on salt extraction. A rotating laser beam at a fixed survey point is launched into the receiver of the salt machine blade and the receiver sends a signal to the saltwater cab indicating whether the blade is above or below or just at the correct cutting level. Precise cutting is important in order to efficiently salt-collect and prevent trenching at the basal surface of a specially prepared salt-crystal pond. This point was judged by the machine operator.
