Abstract
Изобретение относитс к сельскохоз йственному машиностроению, в частности к гидроуправл ющей аппаратуре маркергш картофелепосадочных машин. Цель изобретени - обеспечение независимого управлени маркерами и снижение металлоемкости. Устройство дл гидравлического управлени маркерами с/х машин содержит корпус 1, золотник 2, торцовые полости 3 и 4, пружины 5, маркеры и 8, а также гидромагистрали и гидроцилиндры 11 и12. В процессе работы устройства золотник 2 под действием рабочей жидкости и пружин 5 перекрывает нужную гидромагистраль или открывает ее, в результате чего происходит подъем или опускание маркеров, а при необходимости - поочередности. 4 ил. fe о N) 00 00 V4 Ю Фиг.1FIELD OF THE INVENTION The invention relates to agricultural machine building, in particular, to hydraulic control equipment for marker machines of potato planting machines. The purpose of the invention is to provide independent control of markers and a decrease in metal intensity. The device for hydraulic control of agricultural machine markers comprises body 1, spool 2, end cavities 3 and 4, springs 5, markers and 8, as well as hydraulic lines and hydraulic cylinders 11 and 12. In the process of operation of the device, the spool 2 under the action of the working fluid and the springs 5 closes the desired hydraulic line or opens it, as a result of which the markers are raised or lowered and, if necessary, alternately. 4 il. fe o N) 00 00 V4 Yu Figure 1
