Description
Изобретение относитс к устройствам дл регистрации скорости роста стволов деревьев в толщину.The invention relates to a device for recording the growth rate of tree trunks in thickness.
Известно устройство дл измерени прироста деревьев по толщине, включающее датчик в виде гибкого, заполненного жидкостью шланга, соединенного с регистратором , состо щим из нриводного механизма и самонисца, а также манометр. Однако такой прибор не обладает достаточной точностью измерени , так как на точность вли ют факторы внешней среды: температура и влажность, под действием которых происходит изменение толщины дерева по всему его объему 1 .A device for measuring the increment of trees in thickness is known, which includes a sensor in the form of a flexible hose filled with fluid, connected to a recorder consisting of a driving mechanism and a self-tapping device, and a pressure gauge. However, such a device does not have sufficient measurement accuracy, since the accuracy is influenced by environmental factors: temperature and humidity, under the action of which a change in the thickness of a tree occurs throughout its volume 1.
Известно также устройство дл измерени сезонного прироста деревьев по толщине, включающее пластину с отверстием, направл ющую дл стержн , стержень и фиксирующие элементы дл закреплени пластины на дереве.It is also known a device for measuring the seasonal increment of trees in thickness, including a plate with a hole, a guide for a rod, a rod and locking elements for fixing the plate on a tree.
При замерах в отверстие вставл етс присоединенный к индикатору часового типа щтырь, который касаетс исследуемой части дерева. Такое приспособление не обладает достаточной точностью измерени вследствие того, что щтырь прибора при последующих измерени х может касатьс не одной и той же точки исследуемого дерева, что и в предыдущем измерении, кроме того, неравномерно сминаетс кора дерева под давлением щтыр 2.When taking measurements, a slider attached to a watch-type indicator is inserted into the hole and touches the part of the tree to be examined. Such a device does not have sufficient measurement accuracy due to the fact that the instrument's cane for subsequent measurements may not touch the same point of the tree under study as in the previous measurement, moreover, the bark of the tree under pressure is unevenly crushed.
Цель изобретени - повыщение точности измерени сезонного прироста деревьев.The purpose of the invention is to increase the accuracy of measuring the seasonal growth of trees.
Поставленна цель достигаетс тем, что стержень подпружинен относительно пластины и установлен с возможностью перемещени по направл ющей.The goal is achieved by the fact that the rod is spring-loaded relative to the plate and is mounted for movement along a guide.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Устройство содержит пластину 1, котора на противоположных концах имеет вильчатые прорези 2 и отверсти 3, соответственно ,дл гвоздей 4 и винтов 5 - фиксирующих элементов. В пластине выполнен паз (направл юща ) 6, в котором находитс стержень 7, выполненный в виде иглы с зап тником 8. Стержень подпружинен с помощью пружины 9 относительно пластины. Дл предотвращени люфта стержн имеетс накладка 10.The device comprises a plate 1, which at opposite ends has forked slots 2 and apertures 3, respectively, for nails 4 and screws 5 - fixing elements. The plate has a groove (guide) 6, in which there is a rod 7, made in the form of a needle with a clamp 8. The rod is spring-loaded using a spring 9 relative to the plate. To prevent the backlash of the rod, there is a pad 10.
