Description

TECHNICAL FIELD

[0001] The utility model belongs to the water and soil conservation equipment technical field, concretely relates to a portable field vegetation coverage measuring tool. BACKGROUND

[0002] When investigating the vegetation condition which is one of the factors affecting water and soil loss, the field investigators mostly use the grid method and the needle method, and cooperate with photographing records. Among them, the principle of the grid method is to use a square frame with an area of 1 square meter, which is divided into 100 small squares by a rope inside, to place the square frame in a representative grassland sample point, to count the number of squares occupied by stems and leaves, and to divide the total number of squares to obtain the grassland coverage. The needle method is to mark every 10 cm with a steel tape and a measuring rope, and then to vertically insert a fine needle at these 100 sample points from above the herb, and to record the number of contacts between the needle and the grass in percentage to represent the coverage. In actual work, there are few professional prefabricated tools, and most of them are roughly estimated, and the data is relatively rough. Some prefabricated tools that already exist are not very convenient to carry and use in the field, are easy to damage and not easy to repair and debug, and consume energy. SUMMARY

[0003] The utility model provides a kind of portable field vegetation coverage measuring tool, and monitoring tool is integrated and optimized, more conveniently, safely and accurately complete measurement work, improve work efficiency.

[0004] A kind of portable field vegetation coverage measuring tool, characterized by: including folding frame, string, folding frame includes first square pole and second square pole, the length of first square pole is greater than second square pole, the opposite top surface of first square pole and second square pole is connected using hinge, the distal end of first square pole is provided with lug, the distal end of second square pole is provided with the clamping groove matched with lug, the top surface median line of folding frame is provided with line slot, and line hole is evenly arranged towards the front side of folding frame on the side of line slot;The both ends of string are fixed with limit stop, and limit stop is inserted into line slot and string is worn from line hole.

[0005] Further, the length of the folding frame rod body is 1 m, the cross section is 2 cm*2 cm, and the length of the lug and the clamping groove is 2 cm.

[0006] Further, the radius of the line hole is 1 mm.

[0007] Further, the hinge is a 1.5 cm*1.5 cm hinge.

[0008] The utility model discloses beneficial effect lies in: the tool folding needs to be accomodated, and the one side that is equipped with the snap groove and the lug of two folding frames is opposite splicing, and the periphery is wound with the string, and then the limiting plate of string is inserted into the wire slot, and the binding and the fixed are completed, and it is convenient to carry, avoids the knot of scattering. When using, can open quickly and splice into the square frame body, and the limiting plate of string is inserted into the wire slot and is fixed and is worn from the wire hole and forms the small square of the set number, and the layout is completed, and the tape measure is not needed, and also can be accomodated quickly after using, and it is convenient to use in the field of multiple places.
