Abstract
A seedling height measuring rod relates to a seedling height measuring tool use in forestry investigation. A tubular mother segment (1) and daughter segments (2) are sleeved with each other in a shape descending order to form the seedling height measuring rod; the length of the mother segment (1) is larger than that of each daughter segment (2); each daughter segment (2) is marked with centimeter-unit scale marks; and a portion of each daughter segment (2), which extends out from a last daughter segment thereof, is one meter in length. The seedling height measuring rod has the advantages of simple structure, portable convenience, and capability of greatly improving the efficiency of seedling measurement.
Description
Technical field
The utility model relates to a kind of height of seedling survey instrument that uses in Forestry Investigation.
Background technology
In Forestry Investigation, often need to measure seedling height.At present, normal operation tape measure or altimeter are measured, but use these instruments to have following problem:
1, measure people's height when more when nursery stock is higher than, tape measure can't be measured;
2, when being higher than the nursery stock of measuring people's height with the altimeter measurement, because the measuring accuracy problem often is difficult to satisfy the investigation demand;
3, the nursery stock measurement is different from common forest survey, often needs to measure a large amount of nursery stocks, and no matter with tape measure or altimeter, work efficiency is all very low, and altimeter is subject to the variation of landform.
Summary of the invention
Technical problem to be solved in the utility model is: for the problems referred to above, provide a kind of height of seedling sounding rod, be intended to measure the nursery stock of 10 meters and following height.
Technical solution of the present utility model is: it is to be made of the mother's joint that is tubulose and descending being nested successively of son joint, the length of female joint is greater than each son joint, all indicate take centimetre scale as base unit on the every knot joint, the maximum length that every knot joint stretches out in the joint from it is rice.
Technique effect of the present utility model is: it have advantages of simple in structure, be easy to carry and can increase substantially nursery stock and measure efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, it be by the mother who is tubulose save 1 and son joint 2 descending being nested successively consist of, the length of female joint 1 all indicates take centimetre scale as base unit on every knot joint 2 greater than each son joint 2, and the maximum length that every knot joint 2 stretches out in the joint from it is 1 meter.
Described son joint 2 is nine joints.
The length of described female joint 1 is 1.5 meters.
The lower end of described mother's joint 1 is provided with and ground section 3, and female joint 1 is 1.5 meters with the overall length that reaches ground section 3.
The utility model material is simple glass Steel material or other lightweight sturdy material.For easy to carry, all son joints all are received in female joint.The exsertile length of the first to the 9th every joint of joint is 1 meter, per 1 centimetre of basic scale mark, and per 10 centimetres of high range marks, last scale of every joint is put on successively " 1m " and is arrived " 9m " printed words, and 0 scale is convenient to reading at the first segment starting end.Protelum is female joint, and female joint is not indicated scale, contacts to earth during measurement.
Using method: during measurement and female joint and ground section contact to earth, extract successively the upper various piece that saves out, only have last joint fully to extract out, just take out next joint, until first segment starting end and nursery stock terminal bud are flushed.The reading that intersect the final section of extracting out and female joint upper end adds female joint length, is the height of nursery stock to be measured.
Claims (4)
1. height of seedling sounding rod, it is characterized in that, it is by the mother's joint (1) that is tubulose and son joint (2) descending formation that is nested successively, the length of female joint (1) is greater than each son joint (2), all indicate take centimetre scale as base unit on the every knot joint (2), the maximum length that every knot joint (2) stretches out in the joint from it is 1 meter.
2. height of seedling sounding rod as claimed in claim 1 is characterized in that, described son joint (2) is nine joints.
3. height of seedling sounding rod as claimed in claim 1 is characterized in that, the length of described female joint (1) is 1.5 meters.
