Abstract
A novel measure caliper for wood volume used for measuring and calculating of diameters and volumes of various kinds of round logs and bamboo wood is characterized in that: the measure caliper is composed of two arc ruler sheets combined together through a hinge shaft; an arc ruler plate with scales is arranged on a handle part of one ruler sheet; and a scaled pointer and a positioning handle are arranged on a handle part of the other ruler sheet. The advantages are that: insufficiencies such as complexity of measuring by a tape and large estimation error in the prior arts are overcome; and a measure tool of simple operation, and visual and accurate measuring and conversion is provided for forestry workers.
Description
Technical field
The utility model relates to a kind of measuring appliance, particularly a kind of novel volume of timber measurement slide calliper rule that are used for all kinds of round logs, bamboo wood are carried out diameter, volume of timber measuring and calculating.
Background technology
Bamboo and wood in forest farm, the bamboo plantation is in growth; Need often carry out the measurement estimation of diameter, girth, area and the volume of timber in order to carry out scientific research with the yield by estimation; And conventional measurement is calculated, tables look-up, is converted after being mostly to adopt the tape measuring girth; This measuring method is not only time-consuming, and its accuracy is also relatively poor.
Summary of the invention
The purpose of the utility model provides a kind of easy to use, quick with regard to being to overcome above-mentioned weak point of the prior art, measures the novel accurately volume of timber and measures slide calliper rule.
The purpose of the utility model can adopt following measure to realize:
The volume of timber of the utility model is measured slide calliper rule and is made up of two arc chi sheets that combine through hinge; The shank of one of them chi sheet is provided with the arc chi plate of a band scale, and the shank of another chi sheet is provided with tuning drive gear and position fixing knob.
Be carved with diameter, girth and area, volume of timber conversion scale on the arc chi plate in the utility model.Be carved with diameter, girth scale on the front of its arc chi plate, be carved with at its back side and diameter, the corresponding area of girth scale, volume of timber conversion scale.
The advantage of the utility model is: overcome in the prior art loaded down with trivial details with tape measuring, weak point such as estimation error is big for the forestry worker provides a kind of easy and simple to handle, is measured the intuitive and accurate survey instrument that converts.
Description of drawings
The drawing of accompanying drawing is explained as follows:
Fig. 1 is the front view of the utility model.
Fig. 2 is the front view of the utility model under user mode.
Embodiment
To combine embodiment (accompanying drawing) to be explained in detail below the utility model:
Like Fig. 1, shown in Figure 2, the measurement slide calliper rule of the utility model are made up of two arc chi sheets 1,2 that combine through hinge; The shank of one of them chi sheet 2 is provided with the arc chi plate of a band scale 5; Be carved with diameter, girth scale on the front of arc chi plate; Be carved with at its back side with diameter, the corresponding area of girth scale, volume of timber conversion scale and (when producing this product, also required scale can be set on the chi plate according to actual needs; As shouldn't girth, the area scale, add volume of timber scale etc. at tow sides); The shank of another chi sheet 1 is provided with tuning drive gear 4 and position fixing knob 3.
As using scissors, finger is stretched in the shaking hands of two chi handles when using the slide calliper rule of the utility model, open the cutting edge of slide calliper rule; Forest or bamboo in the face of growth; Block diameter, when degree of tightness is suitable, with position fixing knob under the finger plate; Make two chi sheet relative positionings, can read diameter, girth, area and the volume of timber of measured object through pointer.
