When the cambered rod 45 moves, it will drive the rotating shaft 46 to move, and the rotating shaft 46 will drive the vertical shaft plate 47 to move, and finally move to the required position. At the same time, when the rotating plate 41 moves, it will drive the connecting stretching rod 44 to move, and the control board 6 controls the connecting stretching rod 44 to stretch. When it moves to the required position, the connecting stretching rod 44 will drive the auxiliary shaft When the vertical shaft plate 47 moves, the auxiliary shaft 48 will move the vertical shaft plate 47 along the surface of the rotating shaft 46. At the same time, when the vertical shaft plate 47 is running, it will drive the surface of the arc rotating plate 49 to run along the end surface of the arc rod 45. At the same time, the arc rotating plate 49 will also drive the rack plate 50 to run. When the rack plate 50 runs to the required position, the turning rod pump 7 is started to drive the rack shaft 52 to rotate along the surface of the connecting shaft 53. At the same time, the rack shaft 52 will drive the soil taking rack 54 to run, and the position where the soil needs to be taken is excavated. At the same time, through the rotation of the lateral control rod 43, it is possible to excavate a larger range of soil. At the same time, by controlling the stretching control angle and depth adjustment of the connecting stretching rod 44, the large range of soil required for measurement is finally excavated.At this time, in the collecting component 3, when the operation of the sampling component 2 is completed, the control board 6 buckles the transmission rod 42 to drive the threaded shaft 61 to operate, and the threaded shaft 61 will drive the limiting threaded shaft 62 to rotate through the surface threaded connection, and move up and down. When the limiting threaded shaft 62 rotates, it will drive the card plate 63 to operate, and the card plate 63 will limit the operation of the limiting threaded shaft 62. At the same time, when the limiting threaded shaft 62 operates, it will drive the sleeve plate 64 to operate, and the sleeve plate 64 will drive the soil tooth cylinder 65 to operate, and the soil tooth cylinder 65 will collect the soil in the middle of the soil excavated by the sampling component 2. At this time, there is a gap between the soil to be measured and the surrounding soil, so when the soil tooth cylinder 65 collects, the sampling soil to be measured will not be caused by the squeezing force. Error, when the sampling soil is determined, the control board 6 controls the outer sleeve When the cylinder 66 runs, the outer sleeve 66 will drive the collecting cylinder 67 to stretch and run, and the collecting cylinder 67 will drive the material taking plate sleeve 68 to run. When the running position is required, the control board 6 controls the arc rod 45 to drive the outer sleeve 66 to rotate, and finally drive the material taking plate sleeve 68 to rotate. When the material taking plate sleeve 68 rotates, it will drive the sliding rotating rod 70 to slide along the surface of the arc groove 69, and the sliding rotating rod 70 will drive the stretching material taking plate 71 to rotate. At the same time, through the centrifugal force, the surface of the stretching material taking plate 71 will stretch and expand, and through the fixing effect of another material taking fixing rod 72, finally, the four stretching material taking plates 71 will perform surface sealing on the soil material obtained in the soil taking tooth cylinder 65. When the measured soil is obtained, the directional stretching plate 21 in the moving component 1 runs, driving the measured soil to the collecting tank 12, and finally to the detection box 13.
