Description

Technical Field

[0001] This utility model relates to the field of sampling technology for dead branches and fallen leaves, specifically a sampling device for collecting samples of dead branches and fallen leaves in forests. Background Technology

[0002] The forest litter layer and soil layer retain over 80% of the total water conservation capacity of a forest stand, making them crucial layers for fulfilling the forest's water conservation function. Because the litter layer directly covers the forest surface, it effectively protects the ground and reduces the impact of raindrops. Furthermore, the abundant humus formed during its continuous falling and decomposition improves soil properties and enhances soil permeability, playing a vital role in preventing soil erosion and conserving water. The larger the existing volume of forest litter and the better its water absorption capacity, the greater its water holding capacity and the stronger its water conservation capacity. Therefore, collecting and analyzing the existing volume of litter is crucial for evaluating and analyzing its water conservation capacity.

[0003] According to the announcement number CN219369825U, a forest leaf sampling device relates to the field of forest leaf technology. It includes a fixing component, and a sampling component is fixedly installed on one side of the outer wall of the fixing component. This solves the problem that fallen leaves take a long time to fall, rot, are difficult to collect, and are easy to damage the original structure, which makes the sampling process time-consuming and laborious.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, the device collects naturally falling dead branches and leaves directly into the collection cylinder. However, not only dead branches and leaves fall, but also small particles or broken leaves that are blown by the wind. These are not included in the sampling of dead branches and leaves. Therefore, it is necessary to screen the small particles or broken leaves. Utility Model Content
