[0025] In the present application, before use, the sampling tube 1 is sleeved in the protective tube 7. By inserting the insertion rod 6 into the soil, the positions of the protective tube 7 and the sampling tube 1 can be fixed, which facilitates the subsequent pressing of the sampling tube 1 into the soil for sampling.

[0026] Furthermore, second connecting blocks 16 are fixedly installed on both the front and rear sides of the upper end of the protective tube 7, through holes 17 are opened on the two second connecting blocks 16, movable grooves 8 are opened on both the front and rear sides of the protective tube 7, a movable block 11 is rotatably connected to the top of the sampling tube 1, a guide rail 10 is fixedly connected to the upper surface of the sampling tube 1, the lower end of the movable block 11 is rotatably installed on the guide rail 10, first connecting blocks 12 are fixedly connected on both sides of the movable block 11, rotating rods 13 are rotatably connected to the upper surfaces of the two first connecting blocks 12, the tops of the two rotating rods 13 are fixedly connected to limit blocks 14, and the upper surfaces of the two limit blocks 14 are fixedly connected to knobs 15.

[0027] In the present application, when the sampling work is completed, the partitions 9 are inserted into the mounting grooves 101 in sequence to realize soil stratification, and then the sampling tube 1 is driven to move upward by the driving mechanism 2, and the sampling tube 1 drives the movable block 11 to move upward synchronously, and the movable block 11 drives the first connecting block 12 to move upward until the limit block 14 passes through the through hole 17, and the first connecting block 12 is abutted against the second connecting block 16, and then the limit block 14 and the rotating rod 13 are driven to rotate synchronously by rotating the knob 15, so that the limit block 14 is rotated to be perpendicular to the through hole 17, thereby fixing the sampling tube 1. Through this arrangement, the sampling tube 1 can be fixed in the protective tube 7, which protects the soil sample, prevents the soil sample from falling out during transportation, and also prevents debris from entering the soil sample.

[0028] Furthermore, the driving mechanism 2 includes a mounting plate 201, a screw sleeve 202, a screw rod 203 and a handwheel 204. The mounting plate 201 is fixedly connected to the inside of the top of the protective tube 7.

[0030] The working principle of this utility model:

[0031] First, insert the insertion rod 6 into the soil to fix the positions of the protective tube 7 and the sampling tube 1, so that the sampling tube 1 can be pressed into the soil for sampling later. The hand wheel 204 is turned to drive the screw 203 to rotate. The screw 203 and the screw sleeve 202 cooperate with each other to make the screw 203 drive the sampling tube 1 to rotate and gradually move downward. The annular teeth 3 cut out a contour to allow the soil to enter the sampling tube 1 to achieve sampling. Then, the screw 203 is rotated in the opposite direction to drive the sampling tube 1 to gradually move upward. During the movement, the partitions are moved in turn. 9 is inserted into the installation groove 101 to stratify the soil. The sampling tube 1 drives the movable block 11 to move upward synchronously, and the movable block 11 drives the first connecting block 12 to move upward until the limit block 14 passes through the through hole 17 and the first connecting block 12 abuts against the second connecting block 16. Then, the knob 15 is rotated to drive the limit block 14 and the rotating rod 13 to rotate synchronously, so that the limit block 14 rotates to be perpendicular to the through hole 17, so that the sampling tube 1 is fixed in the protective tube 7 to protect the soil sample. Finally, the insertion rod 6 is pulled out to complete the stratified sampling.

[0032] In summary, this stratified sampling device for soil environment detection can fix the positions of the protective tube 7 and the sampling tube 1 by inserting the insertion rod 6 into the soil, so as to facilitate the subsequent pressing of the sampling tube 1 into the soil for sampling. The screw 203 is driven to rotate by turning the hand wheel 204. The screw 203 and the screw sleeve 202 cooperate with each other through the thread, so that the screw 203 drives the sampling tube 1 to rotate and gradually move downward. The contour is cut out by the annular teeth 3, so that the soil enters the sampling tube 1 to achieve sampling. The sampling tube 1 is driven to move gradually upward by rotating the screw 203 in the opposite direction. During the movement, Insert the partition 9 into the installation groove 101 again to stratify the soil. The sampling tube 1 drives the movable block 11 to move upward synchronously, and the movable block 11 drives the first connecting block 12 to move upward until the limit block 14 passes through the through hole 17 and the first connecting block 12 abuts against the second connecting block 16. Then, turn the knob 15 to drive the limit block 14 and the rotating rod 13 to rotate synchronously, so that the limit block 14 turns to be perpendicular to the through hole 17, so that the sampling tube 1 is fixed in the protective tube 7, which protects the soil sample and prevents the soil sample from falling out during transportation, and also prevents debris from entering the soil sample.
