Description

Technical Field

[0001] This utility model relates to the field of grassland monitoring, specifically a portable, foldable, adjustable grassland sampling frame. Background Technology

[0002] Grassland resources refer to the types, areas, and distribution of grasslands within a specific geographical area, as well as the amount of matter they produce. It is an agricultural natural resource. Grassland resource surveys help people better understand the natural and economic characteristics of grasslands, grasp their quantity, quality, and distribution, and learn about their history, current status, and development trends. Simultaneously, they can also promote the development of grassland science and animal husbandry.

[0003] Traditional field grassland surveys often employ measuring tools such as tape measures, ropes, and steel rulers to create a square frame for on-site measurement. This method of determining the quadrat frame cannot accurately control its boundaries and orientation, and can easily result in irregular shapes, affecting the accuracy of sampling. Alternatively, purchasing sets of flat quadrat frames of different sizes is also problematic, as these sets are inconvenient to carry and fold for storage, causing considerable confusion for surveyors. Utility Model Content

[0004] The purpose of this utility model is to provide a portable, foldable, adjustable grass-like frame, which is a foldable frame structure consisting of eight first folding supports and one second folding support. This frame structure can be folded relative to the second folding support, and its size is small after folding, making it easy to carry.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable foldable adjustable grass sampling frame, the sampling frame consisting of at least eight first folding supports and one second folding support. The eight first folding supports are arranged in a square and connected by steel pipes. The second folding support is located at the center of the eight first folding supports. The four outer corners of the second folding support are connected to the first folding supports by steel pipes. The second folding support and the eight first folding supports are connected to form four square areas. Each square area is provided with a detachable rope assembly. The first and second folding supports each include a cross shaft, a rotating support, a connecting pipe, and a ground plug. The ground plug is provided at the bottom of the cross shaft. The four outer sides of the cross shaft are connected to the rotating support by pins. The rotating support rotates relative to the cross shaft. The front end of the rotating support is integrally formed with a connecting pipe, and the steel pipe cooperates with the connecting pipe.

[0006] Preferably, the connecting pipe is a plug-in pipe or a threaded connecting pipe, and both ends of the steel pipe are provided with plug-in joints or threaded connectors that mate with the connecting pipe.

[0007] Preferably, four slots are spaced apart along the length of the steel pipe, and a scale for indication is provided on one side of each slot. The rope assembly includes eight connecting ropes distributed along the square area and connected to the slots.

[0008] Preferably, each connecting rope includes a rope body and a buckle, wherein the buckle is connected to both ends of the rope body and engages with a groove on the steel pipe.

[0009] Preferably, the first and second folding supports have identical structures, with the eight first folding supports rotating relative to the second folding supports and in both extended and folded-in states. In the folded storage state, the rope assembly on the steel pipe must be removed before folding the eight first folding supports. In the folded state, the sample frame is small in size and does not occupy storage space.

[0010] Preferably, the first folding support can also be set to four according to the measurement requirements, and the four first folding supports enclose a square frame with a length of 50 cm and a width of 50 cm.

[0011] Preferably, eight connecting ropes crisscross within a square area, dividing the square area into multiple square quadrats of equal size. In practical applications, the connecting ropes are 50 cm long, and their ends are connected to the slots on the steel pipe via buckles. The eight 50 cm long connecting ropes crisscross within the square area to form twenty-five square quadrats, each with a length and width of 10 cm. Since there are four square areas, the rope groups within the four square areas can form one hundred square quadrats.

[0012] Preferably, the connecting rope is installed with a buckle, which makes it easy to disassemble and replace the connecting rope. In addition, to facilitate the positioning and installation of the connecting rope, four slots are provided on the steel pipe, and each slot has a scale on one side for indication. During installation, the buckles can be installed point-to-point, which is convenient and quick.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model adopts a folding frame structure consisting of eight first folding supports and one second folding support. The frame structure can be folded relative to the second folding support, and the folded size is small and easy to carry.

[0015] 2. This utility model has four slots on the steel pipe, with a scale for indication on one side of each slot. During installation, the buckles of multiple connecting ropes are simply installed in the corresponding slot positions, which is convenient and quick. At the same time, the connecting ropes are installed through buckles, which makes it easy to disassemble and replace them. Attached Figure Description
