[0004] Although the above paste sampling device can achieve the acquisition of pastes at different depths and can well take out and analyze the pastes at different depths, there are still some defects in this sampling device that need to be improved. Specifically, since the isolation plate is fixed inside the material taking body, it becomes extremely difficult to clean the inside of the material taking body with the help of a water pipe. Especially for the paste remaining on the isolation plate, it is difficult to effectively remove it by conventional means, which undoubtedly adds unnecessary burdens and complexities to the subsequent cleaning and maintenance work.

The positioning rod 63 is inserted into the lifting block 73 to fix the position of the layering isolation plate 71 and prevent it from shaking. When the positioning rod 63 leaves the lifting block 73, the layering isolation plate 71 can be taken out of the sampling bucket 1.

[0027] Reference Figure 1 , A suspension plate 4 is arranged on the extension plate 3 on one side of the fixing frame. A through hole 5 is opened on one side of the suspension plate 4; by setting the suspension plate 4 and the through hole 5, the staff can hook the through hole 5 of the suspension plate 4 with a hoist, which is convenient to take out the sampling bucket 1 from the sedimentation tank.

[0032] Principle and advantages of use: Before use, drive the connecting column 72 to move by means of the lifting block 73, so that the connecting column 72 drives a plurality of layered isolation plates 71 to move. After the layered isolation plates 71 are placed into the material taking bucket 1, drive the cover plate 2 to move by means of the extension plate 3, so that the sealing groove 10 on the cover plate 2 is aligned with the lifting block 73, then press the extension plate 3, the ring block 9 under the cover plate 2 is docked with the ring groove 8 on the material taking bucket 1, so that the lifting block 73 extends out of the extension plate 3. Then rotate the round block 64 to drive the screw rod 62 to rotate inside the mounting frame 61, so that the positioning rod 63 on the screw rod 62 slides under the action of the mounting frame 61. The limiting block 66 connected to the positioning rod 63 slides in the limiting slot 67, making the sliding of the positioning rod 63 more stable.
