A use method of a soil sampling device for land pollution detection, the use method specifically comprises the following steps:

Step 1: Push the entire sampling device to the position to be sampled through the casters at the bottom of the two first flipping legs and the two second flipping legs, then pull out the movable block, and insert the movable block into the card through the card block. Inside the groove, at this time, the two first flipping legs and the two second flipping legs are respectively flipped through the two connecting shafts, and are supported and slid by the casters, so that the two first flipping legs and the two second flipping legs are The spacing between the legs is widened to bring the drill bit into contact with the ground;

Step 2: Connect the motor to the external power supply. After the power is turned on, the output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade and the drill bit to rotate. The hard soil is loose, and while the drill bit is rotating, people hold the handle and press down the support base, and the depth of the sampling cylinder is inserted into the soil while the distance between the two first flipping legs and the two second flipping legs continues to expand. The deeper it is, and when the screw blade rotates, the soil sample is transported to the inside of the discharge pipe through the sampling cylinder, and finally falls into the interior of the receiving barrel through the discharge pipe;

Step 5: Pour out the sample from the inside of the receiving barrel, and put the receiving barrel into the groove again, turn the screw, and push the screw seat to press the outside of the receiving barrel through the screw.

beneficial effect

By setting the flipping mechanism, the movable block is inserted into the card slot through the blocking block. At this time, the two first flipping legs and the two second flipping legs are flipped through the two connecting shafts respectively, and are supported and slid by the casters. The distance between the two first flipping legs and the two second flipping legs is enlarged, so that the drill bit is in contact with the ground. When working, hold the handle to press the support seat down, and between the two first flipping legs and the The distance between the two second flipping legs is constantly expanding, and the deeper the sampling cylinder is inserted into the ground, the flipping function of the legs is available, and there is no need to use tools such as air cylinders, electric telescopic rods, etc. to carry out the lifting and lowering of the auxiliary sampling device. On the one hand, the cost of the device is reduced, and the structure is simple; on the other hand, it also increases the convenience of operation and improves the use effect;

By setting the depth sampling mechanism, the output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade and the drill bit to rotate. The width of the drill bit is larger than the diameter of the sampling cylinder, so the drill bit always contacts the hard soil first, and loosens the hard soil and the screw When the blade rotates, the soil sample is transported to the inside of the discharge pipe through the sampling cylinder, which can facilitate the collection of soil samples of different depths, which greatly improves the effect of sample collection, ensures that the test results are closer to the actual situation, and is more practical. ;

By setting the material receiving mechanism, the collected soil falls into the inside of the receiving barrel through the discharge pipe. When the receiving barrel is full of soil samples, the screw is rotated to drive the compression block through the thread effect between the screw and the screw base. By sliding the slider on the upper part of the chute, the pressing block is separated from the surface of the receiving barrel. After separation, people can take the material between the receiving barrels from the groove, which is more convenient for material receiving, and it is convenient to take the The sample is taken out, and the installation and disassembly of the receiving barrel is very convenient and fast.
