Description
8 лобова стенка 3 и козырек 5 наход тс в приподн том положении и составл ют плоскость, параллельную направлению движени . Лобова стенка и козырек спр мл ютс под действием момента от силы нат жени холостой ветви каната (дальнейшему повороту лобовой стенки и козырька вверх преп тствуют упоры 9 и 10). В таком положении лобова стенка с козырьком легко внедр етс в развал породы . Благодар тому, что козырек оборудован изогнутыми зубь ми, он начинает поворачиватьс в процессе загрузки скрепера , вниз, вокруг шарнира 4, что облегчает услови поворота лобовой стенки вокруг шарнира 2 при закрытии загруженного скрепера. Полное закрытие скрепера лобовой стенкой и козырьком производитс при движении скрепера в обратном направлении под действием рабочей ветви каната. При этом повороту козырька и лобовой стенки при закрытии скрепера, способствует момент, создаваемый разностью нат жений рабочей и холостой ветвей каната, дл чего холоста ветвь каната в это врем подтормаживаетс .8, the front wall 3 and the visor 5 are in a raised position and constitute a plane parallel to the direction of movement. The front wall and the visor are sprung under the action of the moment from the tension force of the idle branch of the rope (stops 9 and 10 prevent further rotation of the frontal wall and the top up). In this position, the front wall with a visor is easily inserted into the rock breakdown. Due to the fact that the visor is equipped with curved teeth, it begins to turn in the process of loading the scraper, downward around the hinge 4, which makes it easier to turn the frontal wall around the hinge 2 when closing the loaded scraper. The full closure of the scraper by the frontal wall and the visor takes place when the scraper moves in the opposite direction under the action of the working branch of the rope. This rotation of the visor and the frontal wall when the scraper closes is facilitated by the moment created by the difference in tension between the working and idle branches of the rope, for which the idle branch of the rope slows down at this time.
