Для приема обрабатываемого дерева приемно-сбрасывающий лоток 1 устанавливают в горизонтальное зафиксированное положение. Для этого гидроцилиндром 6 рычаг 4 перемещают вверх. Гидроцилиндр 5 в этом случае не работает и служит в качестве тяги. Для сбрасывания обработанного дерева вправо от устройства, гидроцилиндром 5 верхнее поворотное звено 3 перемещают в крайнее верхнее положение, поворачивая лоток 1 вокруг шарниров 9 вниз.To receive the processed tree, the receiving-dumping tray 1 is installed in a horizontal fixed position. To do this, the hydraulic cylinder 6, the lever 4 is moved up. The hydraulic cylinder 5 in this case does not work and serves as a traction. To dump the treated tree to the right of the device, the hydraulic cylinder 5 moves the upper pivot link 3 to its highest position, turning the tray 1 around the hinges 9 down.

- Гидроцилиндр 6 в этом случае не работает и служит в качестве тяги. В горизонтальное положение лоток 1 устанавливают гидроцилиндром 5, поворачивая верхнее поворотное звено 3 вниз до среднего положения. Для сбрасывания обработанного дерева влево от ус- . Тройства, гидроцилиндром 6 рычаг 4 ' перемещают в крайнее нижнее положение,.- The hydraulic cylinder 6 in this case does not work and serves as a traction. In the horizontal position, the tray 1 is installed by the hydraulic cylinder 5, turning the upper pivot link 3 down to the middle position. To drop the treated tree to the left of the us-. Trojans, hydraulic cylinder 6, the lever 4 'is moved to its lowest position.

Гидроцилиндр 5 в этом случае не работает и служит тягой,перемещая верхнее поворотное звено 3 в крайнее нижнее положение. Лоток 1 поднимается, поворачиваясь вокруг шарниров 9. Далее циклы работы повторяются.The hydraulic cylinder 5 in this case does not work and serves as a traction, moving the upper pivot link 3 to the lowest position. Tray 1 rises, turning around the hinges 9. Next, the work cycles are repeated.

Таким образом, благодаря установке привода в виде шарнирного четырехзвенника с поочередно работающими гидпоцилиндрами 5 и 6, обеспечивается лю-30 бое из трех фиксированных положений прйёмно-сбрасывающего лотка.Лоток в этом случае выполняет двё функции: приемного устройства и сбрасывающего устройства. Благодаря этому значительно упрощается конструкция устройства и снижается его металлоемкость.Thus, thanks to the installation of a drive in the form of a four-link articulated drive with alternately operating hydraulic cylinders 5 and 6, any of the three fixed positions of the forward-discharge tray is provided. The tray in this case performs two functions: a receiving device and a resetting device. Due to this, the design of the device is greatly simplified and its metal consumption is reduced.
