Description

Soil sample collection equipment

Technical field

The utility model relates to the technical field of soil sampling, in particular to a soil sample collection equipment.

Background technique

Paddy soil is mainly composed of soil particles such as clay, silt, and sand. Its texture is between clay and sand. It has the advantages of good ventilation and water permeability, and good heat and water retention properties. During the rice planting process, the quality of the rice field soil has a relatively important impact on the growth and quality of rice; therefore, the soil in the rice field needs to be sampled and tested during the rice planting stage to ensure rice yield. Chinese patent document CN214200721U discloses a rice field soil sample sampling device. By setting up a sampling mechanism, it effectively avoids the problem that the device is complex in structure and difficult to operate. Due to manual support, the device is prone to tilting during sampling; by setting up a storage structure , effectively avoiding the problem that the device needs to take out the soil sample and store it separately after the sampling is completed, so that the device can directly send the soil sample into the storage tube while sampling, and the storage tube can be directly removed from the device after the sampling is completed. Preserving soil samples effectively improves the convenience of the device. This device only samples soil samples at a certain location through a single sampling tube. The number of samples is small, resulting in inaccurate test results and low reference value. In addition, when the device cuts soil with the blade, soil at different depths will enter. In the sampling tube, the depth of the soil layer corresponding to the soil particles in the sampling tube cannot be effectively distinguished, resulting in errors in sample detection. At the same time, the deep soil will be contaminated by the upper soil, causing inaccuracy in subsequent detection results.
