Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil detection sample preparation and screening device. Background Art

[0002] Soil testing refers to the determination of various physical and chemical properties of soil by using appropriate determination methods. Soil testing is an important measure to understand the status of soil environmental quality. It aims to prevent and control the hazards of soil pollution and dynamically analyze and determine the degree and development trend of soil pollution. Because solid impurities or artificial substances in the soil will affect the test results, a screening device is generally used to screen the soil, and then the screened soil is sampled. In actual use, the screen is generally installed inside the device through multiple sets of fixings. When it is necessary to replace screens with different apertures, tools are required to remove the fixings, disassemble the screen, and then install the fixings to install the replaced screen. This is time-consuming and labor-intensive, and not flexible enough to use. Therefore, a soil testing and sample preparation screening device is now provided. Utility Model Content
