Изобретение относитс к лесной промыш- ле 1ности и может быть использовано при окорке древесины.The invention relates to timber industry and can be used for the debarking of wood.

Целью изобретени вл етс повышение ка чества и упрощение конструкции.The aim of the invention is to improve the quality and simplify the design.

На фиг. 1 показан станок дл окорки бре- ве)н, вид спереди; на фиг. 2 - то же, вид сбоку.FIG. 1 shows a front view of a barking machine; in fig. 2 - the same, side view.

Станок содержит раму 1, механизм 2 пс1перечного перемещени и вращени бревен 3, окорочные элементы 4 в виде уставов- линдрической формы без повреждений дрепроизвод т его окорку. Дл вывода бревна из зацеплени с окорочными элементами включают нат жное устройство 14, которое наматывает трос 13. При этом блоки 11 по- с степенно поднимаютс вверх и при подходе к поперечным брусь м 9 останавливаютс на одной высоте. Бревно в этом случае не касаетс окорочных элементов.The machine includes a frame 1, a mechanism for the ps1 transverse movement and rotation of the logs 3, and the debarking elements 4 in the form of a stat-shaped form without damage make it debarded. To remove the log from engagement with the debarking elements, a tensioning device 14 is turned on, which winds the cable 13. In this case, the blocks 11 gradually rise upwards and, when approaching the transverse bars, the m 9 stops at the same height. The log in this case does not apply to debarking elements.

Предлагаемый станок позвол ет производить окорку бревен с отклонени ми от цил (1нных на всю щирину станка бесконечных ц(;пей с режущими кромками и несущие зубчатые рейки 5, размещенные на опорах 6 с возможностью вертикального перемещени The proposed machine allows for the debarking of logs with deviations from cyl (1 n for the entire width of the machine endless centers (; drink with cutting edges and carrying gear racks 5 placed on supports 6 with the possibility of vertical displacement).

Станок может производить окорку бревен различной длины и одновременную окорку нескольких коротких бревен.The springs are the teeth of the rails and the logs are pulled along the rails. The machine can produce debarking logs of various lengths and simultaneous debarking of several short logs.

Invention Formula

Machine for debarking logs containing a frame, a mechanism for transverse movement and rotation of logs, debarking elements in the form of endless chains installed on the entire width of the machine with cutting edges

The machine works as follows. The log 3 is captured by the mechanism 2

of the transverse movement and rotation of the log;

a and rolls along the rails 5. At the same time, the rails 5, under the convex parts of the log 3, are lifted under the action of the cable 13, and the rails under the concave part of Yrevna are lowered. As the log revolves, and the supports are located at its ends and placed in the guide longitudinal bars, while in the upper part of the support there are hinges for connection with the rail, and at the lower - blocks for communication with the mechanism

and the slats 5 move in a vertical 35 vertical movement, made

direction, copy the surface of the log. The middle axis of the log moves at the same Q height. The chains of debarking elements 4 (fBOHMH cutters act on the log and

Lindrical shape without damage to its production. To remove the log from engagement with the debarking elements, a tensioning device 14 is turned on, which winds the cable 13. In this case, the blocks 11 gradually rise upwards and, at the approach to the transverse bars, the m 9 stops at the same height. The log in this case does not apply to debarking elements.

The proposed machine allows for debarking of logs with deviations from the row of teeth of the rails and dragging of the log along the rails. The machine can produce debarking logs of various lengths and simultaneous debarking of several short logs.

By making the rails over the entire length of the machine and installing them on two joint supports, the construction of the machine is simplified.
