AI Technical Summary
In existing soil structure organic matter stratification sampling and detection devices, soil tends to accumulate on the surface of the sampling tube during use, making it inconvenient to remove the soil.
A drive mechanism is used to lower the moving plate, which embeds the sampling tube into the soil layer and rotates to perform stratified sampling. After sampling, the scraper removes the soil from the surface of the sampling tube, and the handrail tilting device keeps the sampling tube horizontal for easy soil removal.
It simplifies the operation of stratified sampling of soil organic matter, improves sampling efficiency and convenience, and ensures the smooth extraction of soil samples.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soil sampling technology, and in particular relates to a soil structure organic matter stratification sampling and detection device. Background Technology
[0002] Land surveying is an important foundation for land management. Soil sampling is required in land engineering surveying and design. Soil structure is the arrangement and combination of soil particles (including aggregates), which is composed of minerals, organic matter, water, air and microorganisms. Among them, minerals account for 50% of soil volume, while organic matter accounts for only 0.5%-2.5%, but plays a decisive role in soil fertility.
[0003] Chinese patent CN219121763U discloses a soil stratification sampling device for surveying and design. This technical solution, through the setting of a motor, a sampling port and a scraper, allows the motor to be started after the sampling tube is inserted into the soil. When the motor starts working, it drives the rotating shaft and the sampling tube to rotate. When the sampling tube rotates, the scraper rotates accordingly, so that the scraper can scrape the soil around the sampling tube into the inside of the sampling tube during the rotation process, ensuring that the soil is collected into the inside of the sampling tube, improving the success rate of soil sampling, and also improving the efficiency of soil sampling.
[0004] However, during the use of this soil structure organic matter stratification sampling and detection device, soil tends to accumulate on the surface of the sampling tube, making it inconvenient for staff to remove the soil from the sampling tube later, which is detrimental to the sampling work.
