Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling equipment, in particular to a sampling device for soil and water conservation monitoring. Background Art

[0002] Soil sampling in soil and water conservation monitoring is a key step in assessing soil erosion, soil loss and soil quality changes. Soil sampling can reveal the physical, chemical and biological properties of the soil, helping monitoring personnel understand the structure, fertility and pollution status of the soil, and thus determine the extent and speed of soil erosion.

[0003] When extracting soil samples, tools such as shovels are generally used to extract the surface soil of the sampling area, while soil samples deep in the soil layer need to be extracted with the help of equipment such as rotary drilling machines, such as the Chinese utility model patent disclosed by announcement number CN217930871U: a soil sampling device. This application can adjust the sampling depth through a pedal to sample the soil at a specified depth, thereby improving the targeted sampling of soil at each depth. Therefore, when extracting soil samples deep in the soil layer, this application needs to use the spiral transmission plate in the sampling barrel to screw the soil deep in the soil layer. Although this application can realize the extraction of soil deep in the soil layer, after the soil sample in the sampling barrel is discharged, the soil will be loosened and fall to the ground due to the rotation of the spiral transmission plate, thereby mixing soil samples at different depths, thereby affecting the separate extraction of soil samples at different depths, and thus unable to realize the classification of soil samples at different depths.

A second mounting groove 11 is provided at the top of the first mounting groove 4, and a limiting groove 15 is provided at the bottom of the first mounting groove 4. The soil taking pipe 3 is inserted and installed at the lower end of the transmission shaft 2 through the connecting groove 9 and is fixedly connected by a first fixing bolt 10. The first mounting groove 4 is provided on one side of the soil taking pipe 3, so that the disassembly and assembly of the disassembly plate 6 can be realized, thereby facilitating the coordination between the gasoline drive engine 1 and the transmission shaft 2. The soil sampling tube 3 and the disassembly plate 6 are used to extract soil samples. A countersunk hole 12 is opened in the middle of the limit pin 5, and a second fixing bolt 13 is inserted and installed in the countersunk hole 12. The upper end of the limit pin 5 is inserted and installed in the second installation groove 11, and the upper end of the second fixing bolt 13 is threadedly connected to the top of the second installation groove 11.
