[0025] Embodiment 1

[0026] See Figures 1-7, this embodiment provides a positionable soil sampling device for environmental detection, including an installation sleeve 1. The installation sleeve 1 is the main support structure of the entire device, providing support and connection functions to ensure the stable installation of other components. A sampling cylinder 2 is fixedly connected to the bottom of the installation sleeve 1. The sampling cylinder 2 is the main container for collecting soil samples and can firmly insert into the soil to collect samples. During actual use, the operator inserts the sampling cylinder 2 into the soil by pushing the device and controls the sampling depth and position by rotation. Two fixed boxes 31 are fixedly connected to the outer wall of the installation sleeve 1. A ratchet 32 and a rotating ring 33 are rotatably connected to the inner walls of the two fixed boxes 31. An annular groove 34 is provided on the inner wall of the rotating ring 33. A pawl 35 is hinged to the inner wall of the annular groove 34. A spring A36 is fixedly connected to the inner wall of the annular groove 34 and the other end of the spring A36 is fixedly connected to the pawl 35. A connecting shaft 37 is rotatably connected between the two pawls 35. An anti-slip sleeve 38 is fixedly sleeved on the outer wall of the connecting shaft 37. The anti-slip sleeve 38 provides a comfortable operation feel to ensure that the operator can firmly hold the device during rotation and adjustment. A reciprocating threaded cylinder 39 is fixedly connected to the outer walls of the two rotating rings 33. A connecting block 310 is threadedly connected to the outer wall of the upper reciprocating threaded cylinder 39. The other end of the connecting block 310 is fixedly connected to a handle 311. A connecting rod 312 is threadedly connected to the outer wall of the lower reciprocating threaded cylinder 39. The bottom of the connecting rod 312 is fixedly connected to a positioning plate 313. A chute A317 is provided on the outer wall of the installation sleeve 1. The connecting block 310 is slidably connected to the outer wall of the chute A317. A pushing component 4 is assembled on the upper end of the positioning plate 313 and an adjusting component 5 is assembled through the pushing component 4. A limiting plate 314 is fixedly sleeved on the outer wall of the anti-slip sleeve 38. Limiting holes 315 are provided on the top of the limiting plate 314 and the lower fixed box 31. A limiting rod 316 is inserted into the limiting holes 315. The function of the limiting rod 316 is to ensure the fixation and positioning of the device and prevent accidental rotation of the adjusting components during the sampling process. The groove directions of the two ratchets 32 are opposite and are distributed in reverse. A connecting box 8 is fixedly connected to the outer wall of the installation sleeve 1. The other end of the connecting box 8 is fixedly connected to a carrying box 6. A carrying frame 9 is arranged inside the carrying box 6. A carrying box 7 is arranged inside the carrying frame 9. A carrying groove is provided at the upper end of the carrying box 7. The carrying box 6 is a container for collecting soil samples. The carrying frame 9 is arranged inside the carrying box 6 to carry and support the carrying box 7 to ensure that the samples can be stored at the designated position after sampling. The designs of the carrying frame 9 and the carrying box 6 enable the samples to be stored stably and safely.

[0027] During use, when conducting soil sampling, first hold the anti-slip sleeve 38 and then rotate it counterclockwise. As a result, the connecting shaft 37 will drive the upper and lower ratchets 32 to rotate. At this time, the upper ratchet 32 will drive the rotating ring 33 outside it to rotate through the pawl 35 stuck inside its outer side in its ratchet slot. Then, the reciprocating threaded cylinder 39 at the upper end of the rotating ring 33 will rotate accordingly, and the connecting block 310 threadedly connected to its outer wall will slide inside the fixed box 31 and the chute A 317, thereby driving the handle 311 connected to it to move up and down inside the mounting sleeve 1, so as to adjust the appropriate height to suit users of different heights. Then, rotate the anti-slip sleeve 38 clockwise. Similarly, under the action of the connecting shaft 37, the two ratchets 32 will also rotate clockwise. However, at this time, the lower ratchet 32 will drive the lower rotating ring 33 through the pawl 35 on its side, thereby driving the lower reciprocating threaded cylinder 39 to rotate. Then, the connecting rod 312 threadedly connected to its outer wall will move up and down accordingly, so as to drive the positioning plate 313 at its top to move inside the sampling cylinder 2, thereby controlling the amount of soil sampling. After the adjustment is completed, pass the limiting rod 316 through the limiting hole 315 on the outer wall of the limiting plate 314 and insert it into the limiting hole 315 at the top of the lower fixed box 31 to prevent the anti-slip sleeve 38 from rotating during sampling. Then, the user holds the handle 311 with both hands and places the sampling cylinder 2 above the sampling soil. Then, step on the pedal and press downward to insert the sampling cylinder 2 into the soil for sampling.

[0028] Embodiment 2

[0029] See Figures 1-7, the pushing component 4 includes a hydraulic chamber A41, the hydraulic chamber A41 is fixedly connected to the upper end of the positioning plate 313, a hydraulic rod A42 is slidably connected inside the bottom port of the hydraulic chamber A41, a connecting hose 43 is fixedly connected to the upper end of the hydraulic chamber A41, the other end of the connecting hose 43 is fixedly connected to a hydraulic chamber B44, a hydraulic rod B45 is slidably connected inside the other end of the hydraulic chamber B44, the other end of the hydraulic rod B45 is fixedly connected to a fixed block 46, a moving plate 47 is arranged at the front end of the fixed block 46, a chute B48 is formed on the outer wall of the moving plate 47, the fixed block 46 is slidably connected to the inner wall of the chute B48, the moving plate 47 is fixedly connected to a push rod 49, a roller 410 is arranged at the end of the push rod 49 away from the moving plate 47, and the push rod 49 and the roller 410 are closely related to the movement of the bearing frame 9 and the bearing box 6. The push rod 49 pushes out the bearing frame 9 through the roller 410. A tension spring 411 is fixedly connected to the inner wall of the bearing box 6, and the other end of the tension spring 411 is fixedly connected to the bearing frame 9. The function of the tension spring 411 is to automatically retract the bearing frame 9 when there is no sample through the restoring force. Due to the elasticity of the tension spring 411, the bearing frame 9 can be reset to ensure that the device is ready for the next sampling process. Chutes C413 are formed on the sides of the connection box 8 adjacent to the bearing box 6, and the push rod 49 is slidably connected to the chutes C413.

[0030] During use, when the sampling cylinder 2 takes a sample, after the soil enters the sampling cylinder 2, the hydraulic rod A42 at the lower end of the positioning plate 313 can be squeezed. Then, the hydraulic rod A42 will enter the interior of the hydraulic chamber A41. Further, under the action of the connecting hose 43, the hydraulic rod B45 inside the hydraulic chamber B44 will move outward. Thus, the moving plate 47 will be pushed outward by the fixed block 46 at its outer end. Then, the push rod 49 on the outside of the moving plate 47 will push out the bearing frame 9 located inside the bearing box 6 through the roller 410 at its other end, thus preventing the sampled soil from being loaded into the test tube. When the test tube is placed in the bearing groove formed at the upper end of the bearing box 7 inside the bearing frame 9, and at the same time, an openable socket is formed on the outer wall of the bearing box 6. When all the soil inside the sampling cylinder 2 is taken out, in order to prevent the bearing frame 9 from retracting in advance, the cover of the socket can be opened and the insertion rod can be inserted to prevent the bearing frame 9 from retracting in advance. After all the samples are placed, the insertion rod can be taken out. At this time, under the action of the tension spring 411, the bearing frame 9 will be pulled back into the bearing box 6, and then the push rod 49, the moving plate 47, the fixed block 46, the hydraulic rod B45, and the hydraulic rod A42 can all be reset.

[0031] Embodiment 3

[0032] See Figures 1-7, the adjusting assembly 5 includes a pressing plate 51, the pressing plate 51 is fixedly connected to the outer wall of the bearing frame 9, a receiving plate 52 is fixedly connected to the outer wall of the moving plate 47, a spring B53 is fixedly connected to the inner bottom end of the bearing frame 9, the upper end of the spring B53 is fixedly connected to the receiving box 7, a spring C54 is fixedly connected to the bottom of the moving plate 47, and the bottom of the spring C54 is fixedly connected to the inner bottom end of the connecting box 8. A chute D55 is formed in the outer wall of the bearing frame 9, and the pressing plate 51 is slidably connected to the inside of the chute D55. A through groove 56 is formed in the middle partition of the bearing box 6.

[0033] During use, when the receiving box 7 is filled with samples, the weight of the receiving box and the pressure of the samples will affect the bearing frame 9 through the spring B53 at its lower end. Specifically, the receiving box 7 squeezes the spring B53, causing it to compress, and the receiving box 7 slides downward inside the bearing frame 9. As the receiving box 7 moves downward, the pressing plate 51 on the outer wall also descends. Since the lower end of the pressing plate 51 is in close contact with the receiving plate 52, the downward movement of the pressing plate 51 will exert a squeezing force on the receiving plate 52, and the downward movement of the receiving plate 52 further causes the moving plate 47 to move downward. The moving plate 47 is connected to the spring C54. As the moving plate 47 moves downward, the spring C54 will be further compressed. This process realizes pushing the push rod 49 and the roller 410 downward together, and guiding them to move along a predetermined path to the lower end of the bearing box 6 through the through groove 56. This design allows when the upper receiving box 7 is full, when the push rod 49 is pushed outward next time, the bearing frame 9 without samples can be pushed out.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
