Technical Field

[0001] The invention relates to a field environment detection sampling device, in particular to a technology capable of continuous sampling and ensuring sap quality. Background Art

[0002] Sampling and testing tree sap in the wild requires meticulous operation and strict record keeping to ensure the accuracy and reliability of the data. By sampling the sap for subsequent testing, valuable environmental and ecological data can be obtained for scientific research and ecological environment monitoring.

[0003] Usually, during the existing sampling, a sampling cup is tied to a tree through a rope, and then a hole is drilled on the tree, a guide tube is inserted into the hole, and the sap flows into the sampling cup along the guide tube to complete the sampling.

[0004] However, in order to ensure the representativeness of the samples, several samples are usually taken at one location during the current sap sampling process, and the samples are mixed and tested. The sampling cup is tied to the tree by a rope. When the sampling cup is full of sap, the staff loosens the rope, takes away the sampling cup full of sap, and then ties an empty sampling cup to the tree to sample again. In this way, multiple samplings are completed. There will be pauses in the sampling process, and the continuity cannot be guaranteed. The sampling plate full of sap needs to be placed aside until all the sap is collected in the multiple sampling cups. In this way, impurities are easily introduced into the sampling cup full of sap, and the quality of the sap cannot be guaranteed. Summary of the invention

Then the driving part drives the C-shaped plate to rotate, and the sampling cup is rotated to the position of the notch, that is, below the guide tube. At this time, the sap of the tree flows into the sampling cup through the guide tube. When the sampling cup is full, the driving part drives the C-shaped plate to rotate, so that the next empty sampling cup is rotated to the notch position, and the sap is collected again. At the same time, the full sampling cup is moved into the shell until all the sampling cups are full of sap and moved into all the shells, and the sap sampling is completed.

After that, the personnel can sequentially place the plurality of empty sample cups (5) in another storage frame (70) into the plurality of placement grooves (22) on the C-shaped plate (21) to sample the sap again, or fix the device on another tree to sample the sap of the other tree multiple times, thereby realizing continuous sampling of leaves of different trees.

10. The working method of the field environment detection sampling equipment according to claim 5, characterized in that: Includes the following steps; When the sampling cup (5) is placed in the placement groove (22), the spring structure (92) will contract, and the two arc-shaped plates will move toward the inner wall direction of the placement groove (22). When the lower end of the sampling cup (5) is placed in the placement groove (22), the spring structure (92) will stretch, and the two arc-shaped plates will clamp the sampling cup (5) in the placement groove (22). By setting the clamping member (90), sampling cups (5) of different sizes can be placed in the placement groove (22).
