The shape of the support plate 2 is umbrella-shaped, and the umbrella-shaped apex angle is 120 °, which is convenient for the mud sampling tube 3 to sample.

In this embodiment, the shape of the support plate 2 is designed as an umbrella. During the process of inserting the mud extractor into the mud, the contact surface between the mud extractor and the mud is an inclined plane, which can reduce resistance during insertion.

Support plate 2 is provided with 4 dredging tube mounting holes 11, and the both sides of each dredging tube mounting hole is provided with 2 screw holes 14; The mud sample passes through to avoid mud sample confusion. The shape of the mud guide hole is circular, and the number of mud guide holes is set according to the actual situation.

As shown in FIGS. 1 and 3 , the mud sampling barrel 3 includes a mud sample storage part 9 and a mud inlet part 10 . The mud sample storage part 9 is a hollow cylinder, which is easy to take out the mud sample and facilitates cleaning of the mud sampling pipe. One port of the mud sample storage part is provided with two screw holes 4 for connecting with the mud inlet part 10 . The upper part of the mud sample storage part is provided with a buckle 11, which is convenient for lifting; the side wall is provided with a water outlet 5, which is convenient for the water in the sample to flow out. One end of the mud inlet part is provided with two screw hole parts 4, which are correspondingly connected with the screw hole parts 4 on the mud sample storage part; the other end is set in a zigzag structure, which is convenient for inserting the mud sampling pipe into the mud for quick sampling.

As shown in FIG. 3 , the height of the mud inlet part is 10 cm, so as to prevent the mud sample from staying in the mud inlet part 10 too much. The mud inlet part 10 is provided mainly for the convenience of removing the mud sample storage part 9 from the mud fetcher, and is not used for storing samples, and the collected samples are stored in the mud sample storage part 9 .

The assembly process of the mud extractor: first put the mud inlet part 10 into the mud extraction tube installation hole 13 on the support plate 2, and clamp it at the mud extraction tube installation hole 11 through the screw holes 4 on both sides of the mud inlet part; then Correspond the screw hole part 4 on the mud sample storage part with the screw hole part 4 of the mud inlet part, then align the screw hole part 4 with the screw hole 14 on the support plate, and screw the mud sample storage part 9 and the inlet part with a screw nut. The mud part 10 and the support plate 2 are connected as a whole; finally, the connecting rod 1 is welded on the support plate 2, so far, the assembly work of the new mud extractor before sampling is completed.

When sampling, insert the mud extractor into the mud through the handle 8. When the resistance suddenly increases, the insertion work is completed. During the process of inserting the mud extractor into the mud, the mud sample enters the mud sample storage part from the mud inlet part 9 10; Then, put out the mud fetcher through the handle 8 or connect the draw ring 7 with a hinge and put out the mud fetcher by pulling the hinge. After the mud extractor was proposed, the mud sample storage part 9 was taken off for sampling.

The upper position of the mud sample storage part is provided with ring buckle 11, and when mud sample storage part 1 is taken off, it is convenient to take by hand; Avoid being stuck with earth on the outer wall, difficult to operate.

The mud inlet is a hollow cylinder with openings at both ends, with an arc at one end and an oblique cut at the other end; two screw holes 4 are provided at the port of the arc to connect with the screw on the mud sample storage part. The hole parts 4 fit together and then fixed with screws and nuts. The oblique cut is provided to facilitate rapid insertion of the mud inlet 10 into the mud for sampling.

A gasket 12 is also provided at the junction of the mud sample storage part 9 and the mud inlet part 10 to prevent sample leakage.

Example 4:

As shown in FIG. 5 , it is a schematic diagram of the structure of the support plate. In this embodiment, the design is further optimized on the basis of Embodiment 1. The shape of the support plate is umbrella-shaped, and the top angle is 120°, which is convenient for sampling in the mud sample storage 9 . The support plate 2 is provided with 4 mounting holes 13 for the dredging tube, and two screw holes 14 are arranged on both sides of each dredging tube mounting hole, and the mounting holes 13 of the dredging tube can be misplaced so that different depths can be obtained at one time The sample; the support plate 2 is also provided with 4 mud guide holes 6, which are used for the mud samples around the target sample to pass through, so as to avoid mud sample confusion, and the shape of the mud guide holes is rectangular. The number of 3 dredging barrels is 4-8, which can be determined according to the actual situation. The number of mud guide holes can also be set according to the sampling site and requirements.

The diameter of the curved surface of the support plate is 40cm-70cm. Within this range, multiple sampling can be realized and the sampling speed is fast. After exceeding this range, it is difficult and inefficient to take samples in actual operation.
