Description
Technical field
This utility model relates to the forest tree breast diameter survey device of a kind of one man operation, belongs to forestry field investigation apparatus field.
Background technology
The research worker of work on forestry in the wild, needs to investigate forest resourceies.Measuring the diameter of a cross-section of a tree trunk 1.3 meters above the ground of plant trunk is one of important element task content of research worker.Existing common survey tape measure typically can only obtain the circumference datum of plant trunk, but cannot directly read the diameter of plant trunk.Meanwhile, owing to needing first to determine the diameter of a cross-section of a tree trunk 1.3 meters above the ground position of institute's measuring plants trunk with measurement tape measure during measuring, the work load of research worker has therefore been increased the weight of.It addition, when running into plant trunk and being thicker, current measurement tape measure generally requires multiple person cooperational and just can complete to measure, exist single cannot operational issue.But when to plant trunk tree breast diameter survey, owing to the visual field of survey crew is usually above the position of the plant trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground, the tape around plant trunk therefore can be caused to be not necessarily located in horizontal level, thus have impact on the accuracy of data to a certain extent.
ZL200720302256.3 discloses a kind of internal and external circumference chi, and ZL200420089489.6 discloses a kind of measurement tape measure, and ZL201320009090.1 discloses a kind of large diameter cylinder special measurement tape.Although above-mentioned each device devises length scale and corresponding diameter scale in tape, but still also needs to first determine the position of the plant trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground with measurement tape measure, when thicker plant trunk being measured, still there is the single problem that cannot operate simultaneously.
ZL201320038189.4 discloses the measurement tape measure of a kind of one man operation, first the fixing nail in outside is inserted in plant bark to be measured by this device, then the plant trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground is measured, although being capable of the measurement to the plant trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground by one man operation, but still can not determine the position of the plant trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground in advance, also may can have that nail is too short causes the problems such as fixing insecure or nail oversize easy damaged trees.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the forest tree breast diameter survey device of a kind of one man operation, it is possible to is accurately positioned the position of the forest diameter of a cross-section of a tree trunk 1.3 meters above the ground and measures the forest diameter of a cross-section of a tree trunk 1.3 meters above the ground.
For achieving the above object, this utility model takes techniques below scheme: the forest tree breast diameter survey device of a kind of one man operation, it is characterized in that: it includes a pole, be fastenedly connected a measurement tape measure on the top of described pole, connect a level indicator on the top of described measurement tape measure by a draw-in groove.
Length scale and corresponding diameter scale it is provided with in the measuring surface of described measurement band tape.
Described pole length 1.3 meters, at the top of described pole sheathed for anti-skidding and as handgrip part body, the bottom of described pole is arranged to taper.
Described pole uses hollow expansion link, and described hollow expansion link includes the single-unit body that more piece diameter does not waits.
Described measurement tape measure is all connected by screw with between described pole and described draw-in groove.
This utility model owing to taking above technical scheme, it has the advantage that 1, this utility model owing to being provided with a pole, pole total length 1.3 meters, therefore this utility model can be used in determining the diameter of a cross-section of a tree trunk 1.3 meters above the ground position of forest.2, this utility model owing to being fastenedly connected the bottom of a measurement tape measure housing on the top of pole, a level indicator is connected by a draw-in groove on the top measuring tape measure housing, therefore, it is possible to ensure to measure level when band tape measures the forest diameter of a cross-section of a tree trunk 1.3 meters above the ground, this utility model simple in construction, easy to use.3, this utility model is provided with length scale and diameter scale, therefore, it is possible to directly read forest diameter of a cross-section of a tree trunk 1.3 meters above the ground value owing to measuring in the measuring surface of band tape.4, this utility model is at the top of pole sheathed for anti-skidding body, and body can be as hand-held position, and pole bottom is arranged to taper, it is possible to facilitates its insertion into and is fixed in soil, and this utility model has single operability.5, this utility model is due to pole employing hollow expansion link, and hollow expansion link includes the single-unit body that more piece diameter does not waits, and therefore this utility model is easy to carry.6, this utility model measurement tape measure is all connected by screw with between pole and draw-in groove, it is simple to changes and measures tape measure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model proposes the forest tree breast diameter survey device of a kind of one man operation, it includes a pole 1, is fastenedly connected a measurement tape measure 2 on the top of pole 1, a level indicator 4 is connected by a draw-in groove 3, it is possible to ensure to measure tape measure 2 tape level when forest on the top measuring tape measure 2.
In above-described embodiment, measure and be provided with length scale and corresponding diameter scale in the measuring surface of tape measure 2 tape.Wherein, diameter scale is 1/ π of corresponding girth scale.
In above-described embodiment, the total length of pole 1 is 1.3 meters, for determining the diameter of a cross-section of a tree trunk 1.3 meters above the ground (brerast-height diatmeter, trunk diameter at 1.3 meters more than the ground) position of forest.At the top of pole 1 sheathed for anti-skidding body 11, body 11 can be as hand-held position.It is arranged to taper, in order to be inserted in soil in the bottom of pole 1.
In above-described embodiment, measuring and can be connected by screw between tape measure 2 and pole 1, draw-in groove 3 can also be connected by screw between tape measure 2 with measuring, and is so conveniently replaceable measurement tape measure 2.
In above-described embodiment, pole 1 can use hollow expansion link, in order to carries.Wherein, hollow expansion link includes the single-unit body 12 that more piece diameter does not waits.
Pole 1 in use, is first inserted and fixed in ground by this utility model, then pulls the tape measuring tape measure 2 around forest.Then extract pole 1 and determine the diameter of a cross-section of a tree trunk 1.3 meters above the ground position of forest, due to a length of 1.3 meters of pole 1, therefore can directly determine the diameter of a cross-section of a tree trunk 1.3 meters above the ground position of forest.Under the effect of level indicator 4, it is ensured that the tape measuring tape measure 2 can keep level when around forest, the last tape directly using measurement tape measure 2 reads the diameter of a cross-section of a tree trunk 1.3 meters above the ground numerical value measuring forest.
Can use as alpin-stock it addition, hold body 11 of the present utility model, so be conducive to researcher to carry out field work on forestry.
The various embodiments described above are merely to illustrate this utility model; the structure of the most each parts, connected mode etc. all can be varied from; every equivalents carried out on the basis of technical solutions of the utility model and improvement, the most should not get rid of outside protection domain of the present utility model.
