[0007] The present invention provides a soil extraction device for a soil detection device, specifically including: a mounting base; a lifting frame is fixedly installed at the middle position of the top of the mounting base, and a slider is slidably connected to each of the left and right sides of the lifting frame. A threaded hole is provided at each of the left and right sides of the top of each lifting frame, and the two threaded holes of the lifting frame are respectively located above a slider. A threaded rod is rotatably connected to each of the two threaded holes of the lifting frame. The bottom of each threaded rod is rotatably connected to the middle position of the top of a slider. The two sliders are fixedly connected to the left and right sides of a lifting plate. A toothed ring cylinder is installed at the middle position of the lifting plate. A motor A is fixedly installed at the front middle position of the top of the lifting plate. A gear A is fixedly installed at the middle position of the top of the motor A. The gear A is in meshing transmission with the front upper position of the toothed ring cylinder. The bottom position of the toothed ring cylinder is fixedly connected to the middle position of the top of an adjusting frame.

[0008] Further, a conical groove is provided at the lower position inside the toothed ring cylinder, and the inside of the toothed ring cylinder is designed to be through. A limiting ring is installed at the middle and lower position inside the toothed ring cylinder, and a spring member is fixedly installed at the bottom position of the limiting ring.

[0009] Further, the spring member is located at the lower position inside the toothed ring cylinder. The bottom position of the spring member is fixedly connected to the top position of a conical plug. The middle position of the conical plug is designed to be through, and the bottom position of the conical plug is conical. When the spring member is in the extended state, the conical position of the conical plug fits the conical groove position of the toothed ring cylinder.

[0010] Further, a motor B is fixedly installed at the middle position of the bottom of the conical plug, and a spiral member is fixedly connected to the bottom rotating shaft position of the motor B.

[0011] Further, the middle position of the adjusting frame is designed to be through, and an adjusting toothed ring is rotatably connected to the internal space of the adjusting frame.

[0012] Further, a gear B is fixedly installed on the rear rotating shaft of the motor C. The gear B is in meshing transmission with the upper position above the top of the adjusting toothed ring. The spiral member is located at the middle position inside the adjusting toothed ring.

[0013] Further, four sliding grooves are provided at the bottom position of the adjusting frame, and a sliding plate is slidably connected to each of the sliding grooves of the adjusting frame.

[0034] Embodiment 1:

[0035] As shown in the attached Figure 1 to the attached Figure 8 figure:

[0036] The present invention provides a soil extraction device for soil detection equipment, including: a mounting base 1; a lifting frame 101 is fixedly installed at the middle position of the top of the mounting base 1, a slider 102 is slidably connected to each of the left and right sides of the lifting frame 101, a threaded hole is provided at each of the left and right sides of the top of each lifting frame 101, and the two threaded holes of the lifting frame 101 are respectively located above a slider 102. A threaded rod 103 is rotatably connected to each of the two threaded holes of the lifting frame 101. The bottom of each threaded rod 103 is rotatably connected to the middle position of the top of a slider 102. The two sliders 102 are respectively fixedly connected to the left and right sides of a lifting plate 104. A toothed ring cylinder 2 is installed at the middle position of the lifting plate 104. A motor A 105 is fixedly installed at the front middle position of the top of the lifting plate 104. A gear A 106 is fixedly installed at the middle position of the top of the motor A 105. The gear A 106 is in meshing transmission with the front upper position of the toothed ring cylinder 2. The bottom position of the toothed ring cylinder 2 is fixedly connected to the middle position of the top of an adjusting frame 3.

[0037] Among them, a conical groove is provided at the lower inner position of the toothed ring cylinder 2, and the inner position of the toothed ring cylinder 2 is designed to be through. A limiting ring 201 is installed at the middle and lower inner position of the toothed ring cylinder 2. A spring member 202 is fixedly installed at the bottom position of the limiting ring 201. The spring member 202 is located at the lower inner position of the toothed ring cylinder 2. The bottom position of the spring member 202 is fixedly connected to the top position of the conical plug 203. The middle position of the conical plug 203 is designed to be through, and the bottom position of the conical plug 203 is conical. When the spring member 202 is in the extended state, the conical position of the conical plug 203 fits the conical groove position of the toothed ring cylinder 2. A motor B204 is fixedly installed at the middle bottom position of the conical plug 203. A spiral member 205 is fixedly connected to the bottom rotating shaft position of the motor B204.

[0038] Among them, the middle position of the adjusting frame 3 is designed to be through, and an adjusting toothed ring 301 is rotatably connected to the inner space of the adjusting frame 3. A spiral groove is provided at the bottom position of the adjusting toothed ring 301. A motor C302 is fixedly installed at the middle front position of the adjusting frame 3. A gear B303 is fixedly installed on the rear rotating shaft of the motor C302. The gear B303 is meshed and driven with the upper position above the top of the adjusting toothed ring 301. The spiral member 205 is located at the middle inner position of the adjusting toothed ring 301.

[0039] Among them, four sliding grooves are provided at the bottom position of the adjusting frame 3, and a sliding plate 304 is slidably connected to each sliding groove of the adjusting frame 3. The upper position of each sliding plate 304 is meshed and driven with the spiral groove position of the adjusting toothed ring 301. A fan-shaped conical plate 305 is provided at the bottom position of each sliding plate 304. When the four fan-shaped conical plates 305 are in the closed state, the spiral member 205 is located at the middle inner position of the four fan-shaped conical plates 305. When the four fan-shaped conical plates 305 are in the closed state, they jointly form a semi-conical structure.

[0040] During use:

[0041] Place the mounting seat 1 horizontally at the sampling position to ensure its own stability. Rotate the two threaded rods 103 provided on the lifting frame 101 respectively. The synchronous rotation of the two threaded rods 103 will drive the two sliders 102 to slide downward on both sides of the lifting frame 101 synchronously. At this time, the lifting plate 104 slides downward inside the lifting frame 101 following the positions of the two sliders 102, thereby synchronously driving the overall toothed ring cylinder 2 and the overall adjusting frame 3 to slide downward. During the process of height adjustment of the overall toothed ring cylinder 2 and the overall adjusting frame 3, avoid the rotation of a single threaded rod 103 causing the position of the lifting plate 104 to change and affecting the change of the detection depth.

[0042] The whole of the tooth ring cylinder 2 and the whole of the adjusting frame 3 move downward until the bottom position of the fan cone plate 305 touches the ground position. Next, start the motor A105 to drive the gear A106 to rotate. Through the meshing rotation of the gear A106 and the upper position of the tooth ring cylinder 2, the tooth ring cylinder 2 rotates inside the lifting plate 104, and the fan cone plate 305 at the bottom of the adjusting frame 3 drills deeply into the ground position, facilitating the spiral member 205 to reach the soil depth required for sampling.

[0043] When the spiral member 205 is above the soil sampling position, start the motor C302 to drive the gear B303 to rotate. Through the meshing transmission of the gear B303 and the adjusting tooth ring 301, the rotation of the adjusting tooth ring 301 drives the four sliding plates 304 to move and expand in opposite directions, causing the four fan cone plates 305 to unfold, and the four fan cone plates 305 will not block the position below the spiral member 205.

[0044] After the position below the spiral member 205 is not blocked by the fan cone plate 305, continue to lower the whole position of the tooth ring cylinder 2. The bottom of the spiral member 205 touches the position required for sampling to give a force feedback. The spring member 202 contracts in cooperation with the applied force, and the conical position of the conical plug 203 disengages from the conical groove position of the tooth ring cylinder 2. Drive the spiral member 205 to rotate by rotating the shaft of the motor B204. The spiral member 205 spirally conveys the soil at the sampling position upward. The soil will enter the internal position of the tooth ring cylinder 2 through the gap between the conical position of the conical plug 203 and the conical groove position of the tooth ring cylinder 2 for sampling. The spiral member 205 directly extracts the soil at the required sampling position, avoiding the situation that the soil sample is easily polluted by the external environment during the sampling process, which affects the accuracy of the detection results.

[0045] When the soil sampling is completed at the position below the spiral member 205, the spiral member 205 will no longer be subjected to the force of soil adhesion. The spring member 202 will reset, and the conical position of the conical plug 203 and the conical groove position of the tooth ring cylinder 2 will be reset and fitted to prevent the soil collected inside the tooth ring cylinder 2 from detaching from the inside of the tooth ring cylinder 2.

[0046] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure shall be subject to the protection scope of the claims.
