Description

Technical Field

[0001] The utility model relates to the technical field of soil moisture detection, in particular to an electronic probe measuring instrument for soil and water conservation. Background Art

[0002] Soil moisture testing is used to measure the moisture content in the soil. This work is very important for agricultural production and soil protection, because the appropriateness of soil moisture content is directly related to crop growth and soil conservation. By measuring soil moisture content, farmers can determine when to irrigate crops and determine the drainage of the soil to avoid over- or under-irrigation and improve crop yield and quality. In addition, soil moisture testing also plays an important role in soil conservation and prevention of soil erosion.

[0003] However, in the prior art, for example, China Publication No.: CN111024781A, "Multi-electrode soil moisture detector", the present invention belongs to the field of detection equipment, and specifically relates to a multi-electrode soil moisture detector. This multi-electrode soil moisture detector includes a support rod, a sensor probe, an electrode, a telescopic mechanism, and a signal conversion device. The sensor probe is arranged at the bottom end of the support rod, and the electrode includes at least two electrodes. The two ends of the electrode are respectively connected to the sensor probe and the signal conversion device. The telescopic mechanism is arranged on the support rod to drive multiple electrodes to retract or extend with the axis of the support rod at the same time, and the signal conversion device is arranged at the top of the support rod. The multi-electrode soil moisture detector provided by the present invention can solve the problem of adaptability of different soils to electrodes. As the distance between the positive electrode and the two negative electrodes changes, the amplitude of the detection signal also changes accordingly, which is beneficial to increase the amplitude of the detection signal to improve the resolution of the soil moisture sensor.

The detection range of the device is small, resulting in inaccurate measurement results of the device, and it is not suitable for high-precision measurements. The device does not have a detection probe fixing structure, and cannot fix the raised probe. When detecting soil at the same depth, the probe will slip, resulting in the inability to continuously detect the soil at the target depth. Utility Model Content

[0026] like Figure 1-5 As shown, the top of the transmission rod 5 is fixedly connected to a fixed tube 12, the inner surface of the fixed tube 12 is fixedly connected to four connecting plates 13, the side of the four connecting plates 13 away from the fixed tube 12 is fixedly connected to a second motor 14, and the second motor 14 is fixed inside the fixed tube 12 through the connecting plates 13.

[0027] like Figure 1-5 As shown, the output shaft of the second motor 14 is linked with a forward and reverse screw rod 15, and one end of the forward and reverse screw rod 15 away from the second motor 14 is rotatably connected to the top of the transmission rod 5, and the output shaft of the second motor 14 will drive the forward and reverse screw rod 15 to rotate.

[0028] like Figure 1-5 As shown, the outer surfaces of the forward and reverse screw rods 15 are threadedly connected to two internal threaded sleeves 16, and the outer surfaces of the two internal threaded sleeves 16 are rotatably connected to two connecting rods 17. Under the action of the rotating forward and reverse screw rods 15 on the internal threaded sleeves 16, the internal threaded sleeves 16 will move along the direction of the forward and reverse screw rods 15.

[0029] like Figure 1-5 As shown, one end of the two connecting rods 17 away from the internal threaded sleeve 16 is rotatably connected to the transmission rod 18, and the side of the transmission rod 18 away from the internal threaded sleeve 16 is fixedly connected to the inner support rod 19. Under the connecting action of the connecting rod 17, the transmission rod 18, the inner support rod 19 and the inner support plate 20 are pushed outward.

[0030] like Figure 1-5As shown, the outer surface of the inner support rod 19 is passed through the side wall of the fixed tube 12, and the end of the inner support rod 19 away from the transmission rod 18 is fixedly connected to the inner support plate 20, and the side of the inner support plate 20 away from the inner support rod 19 is arranged on the inner surface of the outer extension tube 3.

The first motor 10 is fixed on the working shell 2 by the L-shaped rod 11. After power is turned on, the output shaft will drive the rotating rod 8 to rotate. The gear 9 that follows the rotation will move the transmission rod 5 downward along the positioning groove 4 under the meshing action of the tooth groove 7 and the positioning action of the positioning groove 4 on the positioning bar 6. The detection probe 23 will follow the movement and change the depth from the soil surface. The detection probe 23 mainly determines the moisture content of the soil by inserting it into the soil and through the resistance value. The moisture in the soil will cause a change in electrical conductivity, thereby reflecting the moisture content in the soil. When it is necessary to continuously detect the soil at the target depth , turn on the external power supply of the second motor 14, the external power supply is connected to the second motor 14 through an electric wire, the model of the second motor 14 is: Z2BLD, rated power: 25W; the second motor 14 is fixed inside the fixed tube 12 through the connecting plate 13, and its output shaft will drive the positive and negative screw rods 15 to rotate after power is turned on. Under the action of the rotating positive and negative screw rods 15 on the internal threaded sleeve 16, the internal threaded sleeve 16 will move along the direction of the positive and negative screw rods 15, and the two internal threaded sleeves 16 move in opposite directions. When the two internal threaded sleeves 16 are close to each other, the transmission rod 18, the inner support rod 19 and the inner support plate 20 will be pushed outward under the connection action of the connecting rod 17. When the two inner support plates 20 move outward at the same time, they will be fixed on the inner surface of the extension tube 3 under the action of the inner support force, and fix the transmission rod 5 and the detection probe 23 at the bottom so that they are no longer displaced.
