Abstract
Изобретение относитс к лесной промышленности и может быть использовано в машинах, производ щих обрезку сучьев и раскр жевку поваленных деревьев. Цель изобретени - повышение эффективности раскр жевки путем обеспечени беззажимного пилени . Лесозаготовительна машина содержит основание и поворотную стрелу 2, на которой размещены захватно-сучкорезна головка, протаскивающий механизм и пильный аппарат 5, который смонтирован на стреле через кронштейн 6 и гидроцилиндр 7. Пильный аппарат подвешен к кронштейну 6 посредством рычага 8. Упоры 9, 10 и пружина 11 ограничивают поворот рычага 8 и пильного аппарата 5. Така подвеска пильного аппарата позвол ет одним ходом штока гидроцилиндра 7 надвигать его на ствол сбоку и сверху, что обеспечивает беззажимное пиление. В исходном положении пильный аппарат 5 находитс сбоку стрелы 2 и не задевает за расположенные ниже лесоматериалы. 4 ил.The invention relates to the forest industry and can be used in machines for cutting branches and cutting fallen trees. The purpose of the invention is to increase the efficiency of the cutting by providing a clampless sawing. The logging machine contains a base and a swivel boom 2, on which a head, a pulling mechanism and a saw unit 5, which is mounted on the boom through bracket 6 and hydraulic cylinder 7, are placed on the boom. The saw unit is suspended to the bracket 6 by means of the lever 8. The stops 9, 10 and the spring 11 restricts the rotation of the lever 8 and the saw unit 5. Such a suspension of the saw apparatus allows one stroke of the rod of the hydraulic cylinder 7 to push it onto the trunk from the side and from above, which provides gapless cutting. In the initial position, the saw unit 5 is located on the side of the boom 2 and does not touch the timber located below. 4 il.
