Machinery to control level of coal plough blade - includes chain guide linked to console by several hydraulic cylinders

摘要

The machinery controls the level of a blade plough whose blade grips under a conveyor. A plough chain guide located on the stowing side of the conveyor has chain channels one above (4) the other (5), and the plough blade is coupled to the plough chain in the bottom channel (5). Hydraulic cylinders (19) parallel to the floor are connected at one end with the head (9) of the chain guide (3), and on the other end to a projecting support console bracket (16), which in turn is connected to a guiding rod (12). where seams are not very thick.
