Description

(54) УСТРОЙСТВО ДЛЯ ОКОРКИ стволов ДЕРЕВЬЕВ шие в кору электроды остаютс  неподвижными относительно дерева. Электроды нодвОл; т электрнчсскнй ток к сло м, расположенным под корой, обладающим повышенными влагосодержанне.м н проводимостыо . В результате прохождени  по этим сло м электрического тока температура и.х повышаетс , иод корой образуютс  пары, и св зь древесины с корой ослабл етс . После этого кору можно легко удалить или она отпадает сама. Гибкие замкнутые органы, установленные в виде нескольких кон:центр;ических кругов, при перемещении ствола включаютс  по пор дку. При влагосодержанпи пор дка 50% и напр жении 220 в рассто ние между гибкими замкнутыми органами составл ет от 1 до 3 см, нричем электроды оказывают свое действие в течение 12-17 сек. Дл  более высоких Напр жений это врем  может составл ть несколько секунд. Предмет изобретени  1.Устройство дл  окорки стволов деревьев , включающее несколько расположенных вдоль продольной оси подачи р дов электродов , установленных на раме с возможностью радиального перемещени  п образующих между собой окно дл  пропуска обрабатываемых стволов, п привод радиального перемещени , отличающеес  тем, что, с целью повышени  эффективности окорки, электроды каждого р да укреплены на гибком замкнутом , органе. 2.Устройство по п. 1, отличающеес  тем, что каждый гибкий замкнутый орган снабжен нат жным и зажимным приспособлени ми. 3.Устройство по ни. 1 и 2, отличающеес  тем, что каждый гибкий замкнутый орган подиружинен.(54) DEVICE FOR STRENGTHENING THE BARKS OF TREES The bark electrodes remain stationary relative to the tree. Electrodes of the node; t elec tric current to the layers located under the bark, possessing elevated moisture content and conduction. As a result of the passage of electric current through these layers, the temperature ix increases, the iodine forms a pair of bark, and the connection of the wood with the bark is weakened. After this, the bark can be easily removed or it disappears by itself. Flexible closed organs, installed in the form of several con: center; circles, when moving the trunk, are included in the order. With a moisture content of about 50% and a voltage of 220, the distance between flexible closed organs is from 1 to 3 cm, and the electrodes have an effect for 12-17 seconds. For higher voltages, this time may be several seconds. The subject of the invention 1. A device for the debarking of tree trunks, including several rows of electrodes arranged along the longitudinal axis, mounted on a frame with the possibility of radial movement of the n forming a window for passing the treated trunks, and a drive of radial movement, improving the efficiency of debarking, the electrodes of each row are fixed on a flexible closed organ. 2. The device according to claim 1, characterized in that each flexible closed body is provided with tensioning and clamping devices. 3. The device on nor. 1 and 2, characterized in that each flexible closed organ is spring-loaded.
