刨煤机行程调节指示器是西门子公司生产的TF型和B31型控制部件的扩展装置。它与TF型或B31型控制部件配合可用于长壁工作面上实现任意两个工作点之间自动刨煤,这样可以节省刨煤机操作人员的大量时间。刨煤机行程调节指示器保证刨头自动开关在采煤工作面预定的工作点断开,并高速转向,回到另一工作点。刨头也可用人工操作或实现半自动操作。刨头上按刨煤机的位置面对采煤面装有20个喷咀或几组喷雾装置,均由附加设备控制。
The plow stroke adjustment indicator is an expansion of the TF and B31 control components manufactured by Siemens. It works in conjunction with the TF or B31 control unit for longwall work surfaces to automatically plow coal between any two working points, saving a lot of time for plow operators. Plow stroke adjustment indicator to ensure that the plow automatic switch in the mining face scheduled work point off, and high-speed steering, back to another work point. Plow can also be manually or semi-automatic operation. Planer head by plow position facing the coal face equipped with 20 nozzles or groups of spray devices, are controlled by additional equipment.
