[0019] Embodiment 1

[0020] With reference to Figs. 1-3 The geological survey stratified sampling device comprises a support 1, a first electric telescopic rod 2 vertically fixedly connected to the upper end of the support 1, a mounting frame 4 connected to the telescopic end of the first electric telescopic rod 2, a plurality of through openings equidistantly formed in one side of the mounting frame 4, a sampling cylinder 401 horizontally connected in the through opening of the mounting frame 4, and a driving assembly for driving the sampling cylinder 401 to move, which is mounted on the mounting frame 4.

[0021] The driving assembly comprises a second electric telescopic rod 402, a moving plate 403 and a connecting rod 404, the second electric telescopic rod 402 is fixedly connected to the side of the mounting frame 4 away from the through opening in a horizontal manner, the moving plate 403 is fixedly connected to the telescopic end of the second electric telescopic rod 402, the connecting rod 404 is fixedly connected to the side of the sampling cylinder 401 away from the through opening, and the end of the connecting rod 404 away from the sampling cylinder 401 is fixedly connected to the moving plate 403.

[0022] In the process of geological survey, when it is necessary to sample and detect the soil sample at the survey position, the staff first drills a borehole vertically downward on the specified ground by using a spiral drill, then moves the device to the directly above of the borehole, aligns the device with the center of the borehole as much as possible, starts the first electric telescopic rod 2, and then the first electric telescopic rod 2 drives the mounting frame 4 to move downward into the borehole, after the mounting frame 4 abuts against the bottom of the borehole, the second electric telescopic rod 402 is started, the second electric telescopic rod 402 drives the plurality of sampling cylinders 401 to move simultaneously through the moving plate 403 and the connecting rod 404, so that the plurality of sampling cylinders 401 are inserted into different depth soil layers for sampling, after the sampling cylinders 401 are inserted to the specified depth, the sampling cylinders 401 are controlled to move out of the soil layers and move back to the initial position, then the mounting frame 4 is controlled to move upward out of the borehole by the first electric telescopic rod 2, and then the soil samples taken out of each sampling cylinder 401 are collected, so that the whole sampling work is completed, finally the staff sends the soil samples taken out of different depths to a detection station for detection and analysis, and the required soil sample data can be obtained.

[0023] Embodiment 2

[0024] With reference to Figs. 1-3The geological exploration layered sampling device is basically the same as that in Embodiment 1, and further has the following features: two insertion rods 502 are symmetrically connected to the lower end of the mounting frame 4. When the mounting frame 4 is lowered into the borehole, the insertion rods 502 are inserted into the bottom of the borehole, thereby limiting and fixing the entire device, avoiding the device from tilting and moving when the second electric telescopic rod 402 drives the sampling cylinder 401 to insert into the soil, and effectively ensuring the stability of the device.

When the first electric telescopic rod 2 drives the plurality of sampling cylinders 401 to move downward into the borehole through the mounting frame 4, the driving motor 3 can be started to drive the cleaning gear 5 to reciprocate in a small amplitude when the cleaning gear 5 enters the borehole. The rotating cleaning gear 5 can clean the soil on the inner wall of the borehole, so that the same depth position in the borehole only has the soil sample of the depth position, avoiding the mixing of the soil sample of each depth in the borehole with the soil sample of other depths, thereby facilitating the sampling of the sampling cylinder 401, avoiding the mixing of other soil layer depths in the sampling cylinder 401, and effectively improving the accuracy of subsequent detection and analysis.

[0026] The cleaning gear 5 and the mounting frame 4 are detachably connected through the bolts 501. When the outer teeth of the cleaning gear 5 are damaged after long-term use, the bolts 501 can be twisted to separate the cleaning gear 5 from the mounting frame 4, and then a new cleaning gear 5 can be replaced. At the same time, it is also convenient to replace the cleaning gear 5 according to the diameter of the borehole.
