[0024] A slide bar 5 fixedly connected to the cylinder cover 2 and movable up and down is provided on the mounting seat 16, and a return spring 6 is sleeved on the slide bar 5 between the cylinder cover 2 and the mounting seat 16. Under the action of the slide bar 5 and the return spring 6, the cylinder cover 2 and the sampling cylinder 1 can be separated or closed to adjust the operation, so as to sample the bentonite. A feeding assembly is provided on the bottom surface of the sampling cylinder 1, and a detachable conical seat 7 is also provided for the feeding assembly. The conical seat 7 can facilitate the insertion of the device into the bentonite.

[0025] like Figure 2 and Figure 3 As shown, the feeding assembly includes a feeding tube 8 and a blocking seat 10 in the feeding tube 8, a hexagonal sleeve 9 is fixedly provided in the middle of the outer wall of the feeding tube 8, and the upper and lower ends of the sleeve 9 are respectively provided with external threads, and the bottom surface of the sampling tube 1 and the top surface of the conical seat 7 are respectively provided with internal threaded holes compatible with the external threads, and the two internal threaded holes are located on the same straight line. With the cooperation of the external thread and the internal threaded hole, the feeding tube 8 can be connected to the bottom surface of the sampling tube 1 and the conical seat 7 can be connected to the bottom surface of the sampling tube 1. The setting of the sleeve 9 can effectively tighten the threaded connection between the feeding tube 8 and the sampling tube 1.

[0026] like Figure 3 As shown, a groove 12 is provided on the conical seat 7 above the internal threaded hole, into which the sleeve 9 can be inserted. The arrangement of the groove 12 can ensure the flatness of the contact surface between the sampling tube 1 and the conical seat 7.

[0027] like Figure 3 As shown, a guide surface 17 connected to the internal threaded hole is provided on the inner wall of the sampling tube 1. The guide surface 17 can facilitate the unloading operation of the collected samples.

[0028] like Figure 3 As shown, the outer wall of the plugging seat 10 and the inner wall of the feeding tube 8 are respectively provided with a frustum 11 which cooperates with each other, so that the tightness of the plugging seat 10 and the feeding tube 8 after cooperation can be increased.

[0029] like Figure 3 As shown, a handle 18 is fixedly provided on the top surface of the connecting seat 4, and the handle 18 facilitates the operation of entering and exiting the device.

[0030] Embodiment 2

[0031] Based on the first embodiment, Figure 1 As shown, in order to ensure the tightness of the tube cover 2 and the sampling tube 1 after they are closed, the top end of the slide rod 5 extends to above the top surface of the connecting seat 4, and a pressure plate 13 is fixed on the slide rod 5 below the connecting seat 4, and a return spring 2 14 is also wound on the slide rod 5 between the pressure plate 13 and the connecting seat 4.

When it is inserted to a suitable depth, the limit seat 15 is pulled upward to drive the slide bar 5 to move upward, and at the same time drive the tube cover 2 to move upward, so that the tube cover 2 and the sampling tube 1 are separated. At this time, the bentonite will enter the sampling tube, and then the external force on the limit seat 15 is released. Under the action of the reset spring 2 14 and the reset spring 1 6, the tube cover 2 is driven to automatically move downward, so that it and the sampling tube 1 are closed.

[0033] After sampling is completed, the device is moved out of the bentonite, the conical seat 7 is removed first, and then the blocking seat 10 is taken out from the discharge pipe 8. Under the action of the discharge pipe 8, the sample after sampling is quickly collected, thereby improving the use efficiency of the device.
