[0033] Working principle: Before using this heavy metal soil detection device that is easy to control the sampling depth, you need to check the overall condition of the device to make sure it can work normally. Figure 1- Figure 6 As shown, when sampling, first determine the depth of the soil to be sampled, such as 20-30 cm, then start the electric threaded rod 206 to make the threaded sleeve 207 descend, and the support plate 204 descends through the reinforcement plate 208 and the auxiliary sliding sleeve 203;

[0034] As the electric threaded rod 206 rotates, the straight rod 211 rotates, so that through the driving wheel 212, the belt 213 and the driven wheel 214, the transmission block 218 uses the transmission groove 217 to rotate the sampling knife tube 216, and finally the sampling knife tube 216 is blocked by the blocking cone 307 and drilled into the ground, so that the rotation and descent of the sampling knife tube 216 are controlled by a single motor, saving the manufacturing cost and energy consumption of the equipment, until the depth pointer 209 points to the mark of the depth scale 210 as 20 cm. At this time, the bottom end of the sampling knife tube 216 moves 20 cm below the surface, and the depth pointer 209 points to the depth scale 210 to clearly know the collection depth of the sampling knife tube 216, thereby increasing the accuracy of collection;

[0035] At this time, the first motor 301 is started to rotate the second screw rod 302, so that the screw sleeve 303 drives the blocking cone 307 to move upward through the pull rod 306, and the distance the blocking cone 307 moves upward is determined according to the micro pointer plate 304 pointing to the collection scale 305. When the collection scale 305 is 10 cm, it means that the distance the blocking cone 307 moves upward is 10 cm. The movable blocking cone 307 can prevent the soil close to the surface and not requiring the collection depth from being collected during the descent of the sampling knife tube 216, and the blocking cone 307 can be controlled to rise and fall, so that the depth of the collected soil can be directly controlled to prevent soil at other depths from being collected together, thereby interfering with the detection.

[0036] At this time, the electric threaded rod 206 is continued to be started to make the sampling knife tube 216 rotate and descend until the depth pointer 209 points to the 30 cm scale of the depth scale 210. At this time, the soil collected in the sampling knife tube 216 is the soil at a depth of 20-30 cm.

[0037] Finally, after the sampling knife tube 216 rises, the blocking cone 307 can be used to push the soil out, and the detector 220 above can be used for detection;

[0038] When the sampling knife tube 216 is lifted and lowered, the soil-shoveling inclined block 219 will shovel away the soil embedded in the transmission groove 217 .
