When the operator releases the pressing plate 3022, along with the elastic force of the return spring 3029, the steel needle 3030 is raised and reset to avoid being in a tilted state all the time. When the entire control device 302 shrinks and returns, the return interference with the soil is blocked As a result, the rotating bar 3026 is damaged. The steel needle 3030 is connected with a rotating bar 3026, and the rotating bar 3026 is rotatably connected to the inside of the penetrating shaft tube 3023 through a connecting rod. When directly detecting the soil, the operator will directly pull up the steel needle 3030, and control the reverse rotation of the rotating bar 3026, so that the detection head 3027 is directly inserted into the soil of the layer, thereby realizing the detection, and the detection head 3027 here Similar to the principle of the pin 403 , the humidity and temperature of the soil are also detected through the plug-in contact, and finally the data is transmitted to the display screen 401 for display through an electrical connection. After moving down to a suitable depth, the operator can directly press the pressing plate 3022 when sampling is required to drive the steel needle 3030 to move down. During the downward movement, the rotating bar 3026 connected to it will be driven to rotate in a small range, and the material will be taken. The cover 3028 is pulled out so as to contact the side of the soil at this depth, and the soil is excavated by using the inclination of the retrieving cover 3028 and stored in the inner cavity of the retrieving cover 3028. At the same time, at different heights, multiple a rotating bar 3026, so the detection and sampling of soil at different depths can be realized, so as to realize the effect of sampling and direct detection.

It is worth noting that, please refer to FIG. 6 , the testing device 4 is used for testing the soil after sampling. The detection device 4 includes a display screen 401 , the display screen 401 is electrically connected to pins 403 through wires 402 , and the detection head 3027 is electrically connected to the display screen 401 . If the surface of the soil is directly detected, it is only necessary to insert the pin 403 into the soil to be detected, and the soil temperature and humidity sensor is set on the pin 403, and the insertion of the pin 403 will cause the soil temperature and humidity sensor to The soil is detected, and the detection result is transmitted to the display screen 401 through the wire 402 to realize digital display and provide the most intuitive display for the operator.

Working principle, firstly, as shown in Figure 2, the whole device is in a folded and contracted state, which is convenient for storage and portability. Afterwards, when the operator needs to test and sample the soil, the contact sleeve 114 is aligned with the soil part that needs to be tested and sampled. Then press the insertion strip 109 to form a state of squeezing and shrinking the snap-in spring 110, so that the insertion strip 109 is separated from the position of the draw-in groove 113 of the card seat 112. At this time, the left flat plate 102 and the right flat plate 103 are subjected to the elastic force of the two connecting springs 104 function, the two flat plates will be automatically bounced off to make them flat on the surrounding soil, and the two inserting cones 106 will be directly inserted into the soil, and the whole device will be inserted and fixed in two directions in the soil, and then it will go deep into the shaft tube 3023 and receive Gravity will slide down to move the drill bit 3025 to the upper surface of the soil, and the two support frames 201 will push the top plate 202 to slide under the elastic force of the buffer spring 204 to drive it to unfold, forming the state as shown in Figure 6 .

It also detects the humidity and temperature of the soil through plug-in contact, and finally transmits the data to the display screen 401 for display through an electrical connection. After the detection or sampling is completed, the reverse rotation of the drive motor 304 drives the upward movement of the drill bit 3025, because the helical blade arranged on the drill bit 3025 rotates in the reverse direction, thereby shrinking and resetting the overall control device 302, thereby Raise control device 302 back to position. The operator can collect and store the collected soil according to the retracted control device 302 . And the whole motor will generate a lot of vibration during the operation of the motor. At this time, the vibration force will be transmitted to the connecting sleeve 301, and the vibration force will be transmitted to the two buffer springs 204 through the two support frames 201, so as to ensure the stability of the equipment. The operation provides buffer force, reduces sampling and detection errors caused by vibration, and protects the components of the detection equipment 4, improving the service life and operation stability of the equipment.
