Недостатком данного устройства-является большая металлоемкость.The disadvantage of this device is the large metal consumption.

Цель изобретения - снижение метал- 25 лоемкости установки.The purpose of the invention is the reduction of metal 25 of the installation.

Это достигается тем, что рычаги механизма надвигания размещены на валу приводных звездочек цепного транспортера. 30This is achieved by the fact that the levers of the thrust mechanism are located on the shaft of the drive sprockets of the chain conveyor. thirty

На фиг. 1 показана раскряжевочная установка, вид в плане; на фиг. 2 разрез А-А на фиг, 1.In FIG. 1 shows a bucking installation, a plan view; in FIG. 2 section aa in FIG. 1.

Установка содержит раму 1, на которой расположено приемное устройство 2 лесоматериалов 3 с ограничителем 4. На раме смонтированы также приводной вал 5 и ведомый вал 6, расположенные на опорах 7 я 8. На валах ’ насажены ведущие 9 и ведомые 10 звездочки, на которых натянуты подающие цепные контуры 11 с упорами 12 механизма подачи. Рабочие ветви цепных контуров опираются о. направляющие 13. Механизм надвигания 14 с поворотными рычагами и режущий орган 15 смонтированы на валу 5 соответственно при помощи шпоночного соединения 16 и зажимных скользящих втулок. Вал 5 приводных звездочек цепного транспортера получает вращение.· от электромотора 17 через муфты 18 и 19 и редуктор 20.The installation comprises a frame 1, on which there is a receiving device 2 of timber 3 with a limiter 4. A drive shaft 5 and a driven shaft 6 located on the supports 7 and 8 are also mounted on the frame. The leading 9 and driven 10 sprockets are mounted on the shafts, on which are tensioned feeding chain circuits 11 with stops 12 of the feed mechanism. The working branches of the chain circuits are based on. guides 13. The thrust mechanism 14 with pivoting levers and the cutting element 15 are mounted on the shaft 5, respectively, using the keyway 16 and the clamping sliding bushings. The shaft 5 of the drive sprockets of the chain conveyor receives rotation. · From the electric motor 17 through the clutches 18 and 19 and the gearbox 20.

Для предотвращения выпадания перерезаемых лесоматериалов пространство зоны резания 21 под режущими органами перекрыто ограничительными дугами 22, которые для обеспечения необходимой жесткости и прочности стянуты между собой стяжками 23.To prevent the occurrence of cut timber, the space of the cutting zone 21 under the cutting bodies is blocked by restrictive arches 22, which are tightened together by ties 23 to ensure the necessary rigidity and strength.

На раме 1 ниже радиуса действия поворотных рычагов механизма 14 режу- щего органа 15 расположен механизм выноса разделанных лесоматериалов, выполненный, например, в виде ленточного транспорта 24 с направляющими бортами 25,On the frame 1 below the radius of action of the rotary levers of the mechanism 14 of the cutting body 15 is a mechanism for the removal of cut timber, made, for example, in the form of a conveyor belt 24 with guide sides 25,

Устройство работает следующим образом.The device operates as follows.

Лесоматериалы 3 подаются на приемное устройство 2 и скатываются до or-jq раничитёлей 4, Отсюда они упорами 12 цепей 11 подаются по одному в эону резания, Здесь их подхватывают поворотные рычаги механизма надвигания 14 и протаскивают через режущий орган Ιδης Разделанные короткомерные лесоматериалы падают на выносной транспортер 24 и уносятся из-под раскряжевочной установки к месту складирования или дальнейшей обработки.Timber 3 is fed to receiving device 2 and rolled down to or-jq spreaders 4, From here they are fed with 12 chains 11 one at a time to the cutting eon. 24 and are carried away from under the bucking installation to the place of storage or further processing.

Наличие одного привода и вала, с помощью которого осуществляется подача лесоматериалов и их перерезание, упрощает конструктивное исполнение установки в целом и снижает ее металлоемкость .The presence of one drive and shaft, with the help of which the timber is supplied and cut, simplifies the design of the installation as a whole and reduces its metal consumption.
