[0033] When sampling with the six-stage sieve hole sampler 104 in the detection box 100, first take out the multiple groups of vertical poles 202 in the storage box 201 and connect them end to end. After the multiple groups of vertical poles 202 are spliced, the six-stage sieve hole sampler 104 with the connecting pipe 105 can be rotatably installed on the upper end of the vertical pole 202 at the top. After the six-stage sieve hole sampler 104 is fixedly installed on the top of the vertical pole 202, the pull rod 210 at the front end of the detection box 100 can be pulled out, and the bottom of the vertical pole 202 can be inserted into the installation port 203 at the center of the detection box 100. At this time, according to the six-stage sieve hole sampler, The detection height of the device 104 is adjusted by moving the vertical pole 202 in the installation port 203 downward.
