Description

Technical Field

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

[0002] Soil environmental monitoring is a scientific detection method used to evaluate the quality and health status of soil. By sampling, analyzing and studying soil samples, the quality status of the soil can be understood. After searching, the Chinese patent authorization number CN220171036U discloses a soil detection device, including a conical rod, a control rod is slidably connected to the inside of the conical rod, an L-shaped groove is provided inside the conical rod, the bottom of the control rod extends to the inside of the L-shaped groove and is fixedly connected to a sliding column, the inside of the L-shaped groove is slidably connected to a sliding block, and a through groove is provided inside the sliding block. The beneficial effect of the utility model is that it can be extended into the soil layer through the tapered rod. Since the moisture sensor is located in the L-shaped groove inside the tapered column, the moisture sensor will not be damaged when it is extended into the soil, thereby improving the service life of the moisture sensor. When it is extended to the soil layer that needs to be measured, the control rod is pressed to move the sliding column at the end of the sliding column in the through groove, thereby driving the slider to move in the L-shaped groove, and at the same time pushing the moisture sensor to move out of the L-shaped groove and contact with the soil, so that the soil can be measured more accurately, which greatly improves the accuracy of the measurement data and improves the use effect of the equipment.

[0003] A soil detection device in the above patent has the following shortcomings: when the conical rod is inserted into the soil, the moisture sensor is pushed out of the L-shaped hole by the push of the control rod to realize the detection of the soil. However, since the L-shaped hole cannot be closed, the L-shaped hole will always be filled with soil during the process of inserting and pulling the conical rod into and out of the soil. At this time, after the conical rod is inserted to a suitable depth, the data detected by the moisture sensor is not necessarily the data at that depth, resulting in inaccurate detection data. For this reason, a soil detection device is designed. Utility Model Content

When the hollow plug rod reaches the required depth, the handle is turned to rotate the sleeve, and finally the sensor probe extends from the socket through the strip hole to contact the soil at the depth, effectively solving the problems raised in the background technology, and further realizing that during the insertion process, the sensor probe will not contact the soil at different depths. After reaching the detection position, the socket will be opened, and the sensor probe will be extended to contact the soil at the location for detection, thereby improving the technical effect of the accuracy of the detection.
