The receiving disc 4 is movably arranged below the sampling tube 3 and is used for receiving the sample in the sampling tube 3, the receiving disc 4 is connected with an elastic driven mechanism arranged on the base 1, and the elastic driven mechanism is matched with the thread driving mechanism;
The disc 19 is slidably arranged in the sampling tube 3 and is connected with two groups of elastic locking mechanisms matched with the power mechanism, and the elastic locking mechanisms can release the locking state of the disc 19 so that the disc 19 can perform ejection action on a sample in the sampling tube 3.
In the implementation, the screw thread driving mechanism works forward first and drives the sampling tube 3 to move downwards through the power mechanism, and meanwhile, the screw thread driving mechanism can drive the sampling tube 3 to rotate through the power mechanism, and the bottom end of the sampling tube 3 is arranged in a zigzag manner, so that the smoothness of the whole sampling process of the sampling tube 3 can be ensured;
In the previous descending stroke of the sampling tube 3, the elastic driven mechanism triggers to drive the carrying disc 4 to translate towards the bottom direction of the base 1 so as to ensure that the sampling tube 3 can descend smoothly, after the sampling tube 3 descends to the sampling depth, the screw thread driving mechanism works reversely to enable the sampling tube 3 to ascend, and in the subsequent ascending stroke of the sampling tube 3, the elastic driven mechanism triggers again to drive the carrying disc 4 to reset below the sampling tube 3 so as to carry out carrying on samples in the sampling tube 3;
Then, the elastic locking mechanism is controlled to release the locking state of the disc 19, the disc 19 can move downwards, the sample in the sampling tube 3 is ejected onto the receiving disc 4, and finally, the staff can detect the pressure of the sample on the receiving disc 4.
In summary, the detection method adopts the detection device, and through the mutual cooperation of each mechanism and component, the sampling tube 3 descends and rotates synchronously in the sampling process, so that the smooth sampling process of the sampling tube 3 can be effectively ensured, and the position of the receiving disc 4 can be automatically switched according to the movement condition of the sampling tube 3 through the cooperation of the thread driving mechanism and the elastic driven mechanism, and the problem that the detection result is inaccurate due to the fact that the sample is damaged carelessly in the transferring process can be effectively prevented because the sample is not transferred by using tools in addition by staff.
It should be emphasized that when the screw driving mechanism works reversely, that is, during the ascending process of the sampling tube 3, in order to avoid loosening of the sample inside the sampling tube 3 caused by the rotation of the sampling tube 3, the power of the screw driving mechanism can be properly controlled, so that the ascending process of the sampling tube 3 is ensured to be slowly and stably performed.

When the driving motor 5 drives the screw rods 6 to rotate, the two screw rods 6 synchronously rotate through the first transmission belt 11, the threaded sleeve 7 is in threaded fit with the screw rods 6 to drive the lifting plate 8 to lift, accordingly, the lifting plate 8 drives the sleeve 10 to slide up and down on the rotating shaft 9, so that the lifting function of the sampling tube 3 is realized, meanwhile, the screw rods 6 also drive the rotating shaft 9 to rotate through the second transmission belt 12, and the rotating shaft 9 drives the sleeve 10 to rotate with the sampling tube 3 through the strip-shaped protrusions 901 and the strip-shaped grooves 1001, so that the sampling action of the sampling tube 3 is realized.

In the process that the two threaded sleeves 7 drive the lifting plates 8 to descend, the pulleys 14 roll on the inclined surfaces 1501 firstly, so that the driven plates 15 are caused to yield, the driven plates 15 drive the traversing plates 17 to slide on the two transverse rods 16 away from the vertical plates 2, the second cylindrical springs 25 are compressed, and the traversing plates 17 drive the carrying disc 4 to move towards the bottom of the base 1 through the assembly plates 18, so that the sampling tube 3 can smoothly move downwards;
When the threaded sleeve 7 drives the lifting plate 8 to lift, the pulley 14 is separated from the vertical surface 1502, at this time, the height of the sampling tube 3 is higher than that of the receiving tray 4, and the second cylindrical spring 25 rebounds along with the continuous lifting of the lifting plate 8, and the traversing plate 17 drives the receiving tray 4 to gradually move towards the lower side of the sampling tube 3 through the assembly plate 18, so that the subsequent receiving of the sample in the sampling tube 3 is facilitated.

When the sample in the sampling tube 3 needs to be guided out onto the receiving disc 4, a worker pulls the telescopic rod 22 until the telescopic rod 22 is pulled away from the locking pipe 28, then the third cylindrical spring 29 can rebound to drive the first ring 26 to drive the two vertical plates 20 to slide downwards, and correspondingly, the disc 19 slides towards the outside of the sampling tube 3 to eject the sample in the sampling tube 3 onto the receiving disc 4;
After the sample in the sampling tube 3 is ejected, the worker should pull the telescopic rod 22 again and lift the riser 20 up, so that the first ring 26 slides upwards on the sleeve 10, the third cylindrical spring 29 is compressed, in this process, the first cylindrical spring 24 is also in a compressed state, after the telescopic rod 22 is aligned with the locking tube 28, the telescopic rod 22 is released, so that the first cylindrical spring 24 bounces back, the telescopic rod 22 bounces into the locking tube 28, maintaining the compressed state of the third cylindrical spring 29, and facilitating the ejection of the next sample.
