[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figures 1-3 As shown, a soil testing instrument includes a housing 1, an analyzer 2 mounted on the upper end of the housing 1, four evenly distributed guide rods 3 fixedly connected inside the housing 1, a support plate 4 slidably connected to the outer surface of the guide rods 3, a drive box 5 fixedly connected to the inner side of the support plate 4, a detection cylinder 6 rotatably connected to the lower end of the drive box 5, a drill bit 7 fixedly connected to the lower end of the detection cylinder 6, fixed stakes 8 fixedly connected to the four corners of the lower end of the housing 1, an infrared rangefinder 9 mounted on the lower end of the support plate 4, a protective shell 10 fixedly connected to the upper end of the housing 1, a digital control display screen 11 mounted at the front end of the protective shell 10, the infrared rangefinder 9 and the analyzer 2 being electrically connected to the digital control display screen 11, and a first cylinder 12 fixedly mounted on the upper end of the housing 1, the output end of the first cylinder 12 penetrating through the upper end of the housing 1 and fixedly connected to the upper end of the drive box 5.

[0025] Furthermore, the infrared rangefinder 9 is used to measure the distance between the support plate 4 and the bottom inner side of the outer casing 1.

[0026] Reference Figures 4-6 As shown, one end of the probe cylinder 6 passes through the upper end of the drive box 5 and extends into the interior of the drive box 5. A driven gear 13 is fixedly connected to the outer surface of the probe cylinder 6. A drive gear 14 meshes around the outer periphery of the driven gear 13. A motor 15 for driving the drive gear 14 to rotate is fixedly installed inside the drive box 5 through a support seat.

[0027] Furthermore, by driving the drive gear 14 to rotate via the motor 15, the driven gear 13 can drive the detection cylinder 6 to rotate, which in turn causes the drill bit 7 at the lower end of the detection cylinder 6 to rotate and break up the soil. At the same time, by driving the drive box 5 to move down via the first cylinder 12, the detection cylinder 6 can be moved down and inserted into the soil, reducing the time and physical effort required for manual insertion of the detection rod.

[0028] Furthermore, the probe tube 6 has a hollow cavity 16 inside, and a detection port 17 is opened through the outer surface of the probe tube 6 near the drill bit 7. The detection port 17 has a telescopic groove 19 and a magnetic block 18 on the upper and lower sides respectively. A sealing block 20 is slidably connected inside the telescopic groove 19, and the magnetic block 18 can attract the sealing block 20.

[0029] Furthermore, a second cylinder 21 is fixedly installed at the bottom of the hollow cavity 16, and a sliding block 22 is fixedly connected to the output end of the second cylinder 21. A soil detection sensor 23 is provided at the bottom of the sliding block 22. The soil detection sensor 23 is electrically connected to the analyzer 2. The soil detection sensor 23 can be a soil detection sensor of model such as Decagon Devices GS3.

[0030] Furthermore, the inner bottom end of the sealing block 20 and the end of the sliding block 22 near the sealing block 20 are both inclined surfaces, and the inclination angles of the two inclined surfaces are complementary.

[0031] Furthermore, by pushing the sliding block 22 outward by the second cylinder 21, the two inclined surfaces can come into contact. As the second cylinder 21 continues to push, the sealing block 20 will be pushed into the telescopic groove 19. At this time, the soil detection sensor 23 will come into contact with the soil to detect the soil data. The detected data will be fed back to the analyzer 2 for data analysis. The analyzed data will be transmitted to the CNC display screen 11 in the form of an electrical signal. After the detection is completed, the second cylinder 21 will drive the sliding block 22 to reset. At this time, the sealing block 20 will be reset under the action of the magnetic block 18.

[0032] Furthermore, the CNC display screen 11 includes a touch screen, a microprocessor, and a control system. The first cylinder 12, the motor 15, and the second cylinder 21 are all electrically connected to the CNC display screen 11.

[0033] Furthermore, the lower end of the drill bit 7 is flush with the bottom end of the housing 1, and the measuring end of the soil detection sensor 23 is flush with the inner bottom end of the housing 1. Since the distance from the lower end of the drill bit 7 to the measuring end of the soil detection sensor 23 is fixed, the depth to be tested for soil can be preset through the CNC display screen 11. After the setting is completed, the microprocessor of the CNC display screen 11 will calculate the distance between the support plate 4 and the inner bottom end of the housing 1 when the preset soil detection depth is reached. The calculation process is to subtract the preset value from the initial distance between the support plate 4 and the inner bottom end of the housing 1, and then subtract the distance from the lower end of the drill bit 7 to the measuring end of the soil detection sensor 23.

[0034] Working principle: In use, four fixed stakes 8 are inserted into the soil. Then, the depth to be tested for soil is set through the touch screen of the CNC display screen 11. After input, the microprocessor of the CNC display screen 11 calculates the distance between the support plate 4 and the bottom inner side of the outer shell 1 when the depth is reached. Then, the first cylinder 12 and the motor 15 are started. The motor 15 drives the drill bit 7 to rotate, and the first cylinder 12 drives the probe tube 6 to move downward, thus inserting the probe tube 6 into the soil. The infrared rangefinder 9 monitors the distance between the support plate 4 and the bottom inner side of the outer shell 1 in real time. When the distance between the support plate 4 and the bottom inner side of the outer shell 1 is equal to the distance calculated by the microprocessor, the probe tube 6 will be inserted into the soil. When the values ​​are equal, the power supply to the motor 15 and the first cylinder 12 is cut off. At this time, the second cylinder 21 is started, and the second cylinder 21 pushes the sliding block 22 to move outward, which allows the sliding block 22 to push the sealing block 20 to retract into the telescopic groove 19. At this time, the soil detection sensor 23 comes into contact with the soil and detects the soil at a specified depth. The soil detection sensor 23 transmits the detected data to the analyzer 2 in the form of an electrical signal for data analysis. The analyzed data is transmitted to the CNC display screen 11 in the form of an electrical signal. The detected data can be observed and recorded through the touch screen of the CNC display screen 11.
