Description
Описываемый прибор (дендрометр) дл измерени прироста ствола дерева по окружности снабжен дл охвата последнего гибкой лентой.The described device (dendrometer) for measuring the growth of a tree trunk around the circumference is provided to cover the latter with a flexible tape.
Отличительна особенность прибора заключаетс в том. что он снабжен индикатором с повышающей зубчато-рычажной передачей. Последн кинематически св зана с одним концом ленты, другой конец которой соединен с корпусом индикатора, прикрепл емого к стволу шурупом . Такое выполнение прибора обеспечивает повышен)1е точности измерени прироста дерева.A distinctive feature of the instrument is that. that it is equipped with an indicator with up-gear-linkage. The latter is kinematically connected to one end of the tape, the other end of which is connected to the body of the indicator attached to the barrel with a screw. Such an embodiment of the device provides improved accuracy of measuring tree growth.
На фиг. 1 схематически изображен вид прибора сверху; на фиг. 2- вид его спереди.FIG. 1 shows a schematic top view of the device; in fig. 2 - view from the front.
Непосредственно измер емой посредством прибора величиной вл етс длина окружности ствола в плоскости измерени , что дает возможность определить средний, прирост по диаметру в данной плоскостиThe value directly measured by the instrument is the length of the circumference of the barrel in the measurement plane, which makes it possible to determine the average, diameter increment in this plane
по формуле: Д, - DO д. где: Z)i - DO - разность средних диаметров ствола между наблюдени ми, то есть искома величина среднего прироста, а Lj - LQ - изменение длины окружности ствола запериод наблюдени .According to the formula: D, - DO d. Where: Z) i - DO is the difference in mean trunk diameters between observations, i.e., the desired magnitude of the average increase, and Lj - LQ is the change in the circumference of the trunk during the observation period.
Нрибор состоит из двух основных частей: гибкой ленты /, корпуса рулетки 2, и индикатора с повышающей зубчато-рычажной передачей с отношением числа оборотов ее первой и последней шестере 3 и , равным 3 : 120. На оси шестерни 4 укреплена измерительна шкала.The device consists of two main parts: a flexible tape /, the body of roulette 2, and an indicator with overdrive-lever transmission with a ratio of the speed of its first and last gear 3 and equal to 3: 120. A measuring scale is fixed on the axis of gear 4.
Дл измерени прироста корпус 5 индикатора укрепл етс на стволе дерева посредством шурупа 6 и двух шипов 7. Измерительна лента / выт гиваетс из корпуса рулетки, обертываетс вокруг ствола и подключаетс к индикатору посредством жесткого замка 8. Затем вращением по часовой стрелке головки 9 стержн рулетк, к которому прикреплен конец ленты, производитс нат жение ленты до тех пор, пока шестерн 3 индикатора не сдвинетс с места (что будет видно по шкале отсчетов). После этого лента закрепл етс на корпусе 5 посредством закрепительного винта W. Дл обеспечени нат жени ленты во врем To measure the increment, the indicator body 5 is fixed on the tree trunk by means of a screw 6 and two spikes 7. The measuring tape / is pulled out of the roulette body, wrapped around the trunk and connected to the indicator by means of a hard lock 8. to which the end of the belt is attached, the belt is tensioned until gear 3 of the indicator moves from its place (as will be seen on the scale of readings). Thereafter, the tape is fixed on the housing 5 by means of a fixing screw W. To ensure the tension of the tape during
