An opening 11 is provided at the opening 11, and an opening door 10 is provided. The upper end surface of the piston ring 15 is connected to a first moving member 7 through a moving rod 14. The first moving member 7 is used In order to control the piston ring 15 to move up and down in the ring groove, a connecting tube 16 connected to the bottom of the ring groove is provided on the axis of the ring groove, and a piston disc 17 is slidably connected in the connecting tube 16. The lower end of the piston disc 17 is connected to a probe 20. The ring groove 19 above the piston ring 15, the connecting tube 16 above the piston disc 17, and the connection between the ring groove 19 and the connecting tube 16 are all filled with filling pieces. The filling pieces can be air or filling objects, and the filling objects can be expansion balls, liquids, solid powders, etc.

[0023] When it is necessary to test the soil, the detection part is inserted into the soil to be tested, and then the first movable part 7 is controlled to drive the piston ring 15 to move downward first, driving the protective tube 8 to squeeze the soil, so that a detection groove for accommodating the protective tube 8 is squeezed out of the soil, and then the first movable part 7 drives the piston ring 15 to move upward. Since the connecting tube 16 is connected with the ring groove 19, the piston ring 15 moves upward and drives the piston disc 17 to move downward in the connecting tube 16. The probe 20 squeezes open the door 10, and the opened door 10 swings around the second hinge shaft 9. The probe 20 extends out of the protective tube 8 and extends into the detection groove. The probe 20 is convenient for testing the soil without contacting the soil, reducing the probability of the probe 20 being damaged by hard objects in the soil.

[0024] The connection point between the annular groove 19 and the connecting tube 16 is connected with an input pipe, and a control valve is provided on the input pipe. The input pipe is connected with a filling device. When the amount of the filling piece needs to be adjusted, the filling piece can be air, and the filling device is a fan at this time; the filling piece can be water, and the filling device is a box body at this time, and water is installed in the box body. A water pump is provided on the box body, and the water pump is started to input the water in the water tank into the connection point between the annular groove 19 and the connecting tube 16.

When the probe 20 needs to contact the soil, the first motor is started to drive the first rotating shaft to rotate, and then drive the probe 20 to swing and contact the soil, so that the probe 20 contacts the soil to perform contact detection on the soil. The probe 20 contacts the soil on the side wall of the detection groove, reducing the probability of the probe 20 being damaged by hard objects in the soil.

[0026] The opening door 10 and the side wall of the opening opening 11 are hinged by a second hinge shaft 9, and a second torsion spring is provided on the second hinge shaft 9. The two ends of the second torsion spring are movably connected or abutted with the opening door 10 and the side wall of the opening opening 11 respectively. A limiting plate is provided on the inner wall of the protective tube 8. When the opening door 10 closes the opening 11, the limiting plate abuts against the opening door 10. When the opening door 10 swings outward to open the opening 11, the probe 20 squeezes the opening door 10 so that it can pass through the opening 11 to come to the detection groove to detect the soil.

[0027] The upper end of the piston disc 17 is connected to the inner upper part of the connecting tube 16 through a connecting spring.

The height of the lower end of the probe 20 is higher than the height of the lower end of the protective rod 12. At least one protective rod 12 is provided on the side of the probe 20 close to the second hinge shaft 9. The setting of the protective rod 12 makes it easier for the protective rod 12 to squeeze the door 10 open, so that the probe 20 does not need to contact the open door 10, thereby improving the service life of the probe 20.

[0029] When the number of the protective rods 12 is more than one, multiple protective rods 12 are arranged at equal angles around the probe 20. When the probe 20 needs to enter the soil, the arrangement of multiple protective rods 12 facilitates the protection of the probe 20, further improving the service life of the probe 20.

[0030] The first moving member 7 is used to control the upward and downward movement of the protective tube 8. The first moving member 7 includes a first driving telescopic rod, and the telescopic end of the first driving telescopic rod is connected to the moving rod 14 arranged in the annular groove.

The two toggle plates 3 form an arrow shape, and the angle of the arrow is less than 90 degrees. The two toggle plates 3 are convenient for extending into thicker soil. After the toggle plates 3 extend into the soil, the protruding block 6 can be moved downward by the second moving part, squeezing the two toggle plates 3 to swing in opposite directions, squeezing the soil on both sides, and the protruding block 6 contacts the soil under it, which is convenient for the probe 20 to detect the soil. In addition, the two toggle plates 3 are also convenient for detecting and protecting the probe 20.

[0034] Elastic wrapping pads 5 are provided on both sides of the first hinge shaft 4. The two ends of the elastic wrapping pad 5 are respectively connected to the detection body 1 and the side wall of the toggle plate 3, so as to reduce the contact of soil with the first hinge shaft 4, thereby affecting the swing efficiency of the toggle plate 3.
