Problems solved by technology

Therefore, the function of the probe is single when used in the field. When measuring samples of different depths, the number of probes is too many, the operation is cumbersome, and it is very inconvenient.
In addition, the longer the probe length is, the lower the detection accuracy will be. For deeper soil layers, too long probes will affect the accuracy of measurement indicators, which will have a huge impact on the overall research work.
In addition to the above problems, if the probe encounters hard substances in the deep soil layer or the probe is too long, it is easy to deform, which will also have a great impact on the detection accuracy of the indicator.

Embodiment 1

[0017] Embodiment 1: as figure 1 and figure 2 As shown, it includes a protection tube 1 and a long rod 2. The protection tube 1 is made of stainless steel, has high stress strength, strong corrosion resistance, and can be used for a long time. The head of the protection tube 1 is a solid steel back cover, and a sealing ring is installed at the bottom of the protection tube 1 to play a waterproof role. The long rod 2 is inserted into the protection tube 1, and 8 probes 3, 8 sensor chambers 4 and 8 force plates 5 are installed in the protection tube 1 from top to bottom. The probe 3 is selected according to the needs of the measurement index For functional probes, the size of the probe 3 is required to be as small as possible, and the shorter the length, the better without affecting the measurement accuracy. The force-receiving piece 5 is arc-shaped, and is made of an alloy material with light weight and high strength. Four push blocks 7 are fixedly connected from top to bot...

Abstract

The invention discloses a multi-depth multi-index soil property detection rod. The detection rod comprises a protective pipe (1) and a long rod (2). The long rod (2) is inserted into the protective pipe (1). A probe (3), a sensor chamber (4) and a stress piece (5) are installed inside the protective pipe (1). A pushing block (7) is installed below the stress piece (5). A micro-sensor is placed into the sensor chamber (4) and connected with the probe (3). A spring is connected between the micro-sensor and the stress piece (5). An adjusting bolt (8) and a handle (9) are installed at the tail of the long rod (2). The head and the tail of the protective pipe (1) are provided with a head threaded joint (10) and a tail threaded joint (11) respectively. Different-depth multi-index measurement can be performed so as to adapt to multi-depth multi-index detection tasks, and meanwhile the detection rod is easy to carry and operate, high in maneuverability and quite suitable for field application.

Description

technical field [0001] The invention relates to a soil index detection device, in particular to a multi-depth multi-index soil property detection rod. Background technique [0002] Existing probe-type detectors for various soil indicators can only measure one indicator with one probe when in use, and if multiple indicators need to be measured, interface conversion is required to realize the connection of multiple probes. Therefore, the function of the probe is single when used in the field. When measuring samples of different depths, the number of probes is too many, the operation is cumbersome, and it is very inconvenient. In addition, the longer the probe length is, the lower the detection accuracy is. For deeper soil layers, too long probes will affect the accuracy of measurement indicators, which will have a huge impact on the overall research work. In addition to the above problems, if the probe encounters hard substances in the deep soil layer or the probe is too long...
