The collection cylinder 06 is used to pull the driven end of the collection needle tube 07 and make the inner cavity of the collection needle tube 07 in a low-pressure state; the collection needle tube 07 is made of metal; the collection end of the collection needle tube 07 is in the shape of a needle tip tube, and the inner cavity of the collection needle tube 07 is cylindrical, similar to an air pump, and a rubber piston is provided in the inner cavity. The driving end of the collection cylinder 06 is installed with the rubber piston, and the rubber piston can be used to draw or release the inner cavity of the collection needle tube 07 through the reciprocating motion of the driving end of the collection cylinder 06;

After moving to the sampling location (level location), the controller is started. The controller first controls the displacement cylinder on the displacer, and the collection mechanism is sent to the specified position through the displacement slide. The controller then controls the lifting cylinder of the lifter to descend. Since there is a carrier plate bracket on the lifting end of the lifting cylinder, the displacer can be steadily lowered and inserted into the road surface to a certain depth through the collection needle tube. Then the controller controls the collection cylinder to raise the rubber piston, which will form a low pressure state in the collection needle tube. The internal liquid and compatible substances or small particles of the road surface will be drawn into the collection needle tube as a collection sample; if two samples need to be collected at this location, two collection cylinders can be controlled to collect at the same time. If one sample needs to be collected, one collection cylinder can be controlled to collect; the collected sample is raised by the lifting cylinder, and then the control vehicle moves to send the sample to the recovery sample location, and the collection cylinder pushes the sample in the collection needle tube to the recovery sample location.
