Description
Technical Field
The utility model belongs to biological sampling field, concretely relates to simple and convenient type square frame.
Background
In field investigation of agricultural and forestry research and plant teaching, in order to quickly obtain various related data such as biodistribution quantity, frequency, growth characteristics, coverage and the like in an investigation area, a sample block is often required to be investigated and sampled in a representative sample block and in a specified area.
At present, a common sample square frame in a test is formed by welding four fixed sample square frames with equal side length by adopting reinforcing steel bars, so that the sample square frame is inconvenient to carry and easy to deform, and a test result is influenced. When the sample of different specifications need to be set, the sample frame of fixed length of side can't satisfy the requirement. In addition, the welding is carried out in the sample square frame process, four sides are not guaranteed to be equal, four corners are not right angles, and the sampling accuracy is affected.
In addition, in the process of research and study, if the plant coverage needs to be measured, the sample boxes cannot meet the test requirements. At present, a needle punching method or an estimation method is mostly adopted for measuring the coverage of the plants, wherein the needle punching method adopts a reinforcing steel bar or an iron wire to fix a sample prescription with 100 points, the sample prescription is often placed on a sample ground for measurement, and when the plants are too high, the sample prescription is covered, so that the plants are bent, and the test accuracy is influenced; the estimation method has the defects that the test accuracy cannot be guaranteed due to personal professional level difference, and the accuracy is low particularly for beginners.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a simple and convenient type style square frame has simple structure, convenient operation, advantages such as accuracy height.
The utility model provides a following technical scheme:
the utility model provides a simple and convenient type square frame, includes first rectangle frame, four spinal branch vaulting poles are upwards extended perpendicularly respectively to the four corners department of first rectangle frame, four the bracing piece top is equipped with second rectangle frame, second rectangle frame coats and is stamped the coverage net, the coverage net passes through the clip to be fixed on second rectangle frame.
Preferably, the four sides of the first rectangular frame, the four sides of the second rectangular frame and the four support rods are all telescopic rod pieces with adjustable lengths.
Preferably, the telescopic rod comprises a hollow outer sleeve, and two ends of the outer sleeve are respectively provided with an inner inserted rod which is in inserted connection with the outer sleeve.
Preferably, the outer sleeve and the inner inserted rod are provided with scales.
Preferably, the bottom of the first rectangular frame is provided with a soil breaking cone which is inserted into soil to perform a fixing action.
The utility model has the advantages that:
1. the utility model discloses simple structure, convenient operation, the accuracy is high, is convenient for remove and transport.
2. The utility model discloses a four sides of first rectangle frame, four sides of second rectangle frame are the flexible member that can adjust self length and mark the scale, can be according to the accurate sample square area of setting for of experimental needs.
3. The utility model discloses a first rectangle frame bottom is equipped with the awl of breaing ground, easily inserts the stability that ground strengthened the appearance square frame, can prevent to survey the sample in-process and receive uncontrollable factor to cause the removal of appearance square frame, influence the sample effect.
4. The utility model discloses a lid degree net passes through the clip to be fixed on second rectangle frame, and the size of its lid degree net can be adjusted according to experimental purpose at will.
5. The utility model discloses a four spinal branch vaulting poles just are marked the scale for the flexible member that can adjust self length, can be according to the plant height, the height of adjustment bracing piece to in accurate survey plant coverage.
