[0002] As an important building material, the quality of cement is directly related to the safety and stability of civil engineering, water conservancy, national defense and other projects. During the production and use process, the inspection of cement products is very important, among which sampling is the key link. The traditional method of sampling bagged cement usually randomly selects multiple parts for sampling through a sampling tube, but this method often cannot ensure the effective sampling of samples at different depths of the same bag of cement, and cement at different depths is easily mixed during the sampling process, which affects the subsequent test results.

[0003] Although the existing sampling devices have solved the problem of sampling efficiency to a certain extent, they still face many challenges when inserting and sampling bagged cement. First, the texture and density of cement at different depths may be different. Therefore, the sampling device needs to be able to adjust the elastic force according to different depths to ensure that the sampling structure can be smoothly inserted and representative samples can be taken out. Secondly, the sampling process needs to prevent the mixing of cement at different depths to ensure the accuracy and reliability of sampling.

[0005] Although the device in the above-mentioned document can adjust the deflection through the fixed frame, adjust the sampling point, and perform multi-point sampling of the finished cement product, the device in the above-mentioned document cannot adjust the elastic force of the device according to the cement at different depths to ensure that the sampling structure can be smoothly inserted and representative samples can be taken out. Secondly, the device in the above-mentioned document cannot prevent the mixing of cement at different depths during the sampling process, which will affect the accuracy and reliability of the sampling.

The connecting rod 51 is used to drive the operating rod 45 to rotate, so that the operating rod 45 can be used to drive the blocking tube 433 to reset, and then the blocking tube 433 is used to close the sampling port of the sampling tube 431 to prevent other layers of cement from flowing into different sample storage chambers when the sampling structure 4 is taken out of the cement, thereby affecting the quality of subsequent detection. When the sampling structure 4 completes sampling, the sampling structure 4 is taken out of the cement, and then the sampling structure 4 is reset. By resetting the sampling structure 4, other structures can be driven to reset.

[0051] The working principle of the sampling device for testing finished cement products will be described in detail below.

[0052] like Figure 1-11 As shown, when it is necessary to sample the bagged cement, first, the elastic force of the spring three 6 needs to be adjusted according to the depth of the bagged cement. The top cover 3 and the protective block 1 are fixed by the cooperation of the plug and the fixed block, so the position connection between the top cover 3 and the protective block 1 can be released by sliding the plug out of the inner cavity of the fixed block, and then the threaded block 52 is rotated on the upper part of the connecting rod 51, and the threaded connection between the connecting rod 51 and the threaded block 52 is utilized to drive the threaded block 52 to adjust its position. At the same time, in the process of adjusting the position of the threaded block 52, the connecting block 53 can be driven to adjust its position together, thereby driving the guide rod 2 71 and the push block 7 to adjust their positions together. Then, when the position of the push block 7 on the outer surface of the connecting rod 51 changes, the spring three 6 can be driven to contract or extend, so that the elastic force of the spring three 6 can be adjusted as needed.

[0053] Then, the lower end of the protective block 1 is placed on the surface of the bagged cement, and then a force is applied to the push rod 22 to drive the push rod 22 and the connecting plate 1 23 to slide in the inner cavity of the shell 1 21, and then the protrusion 24 is pushed to slide in the inner cavity of the limiting groove 12, so that the protrusion 24 can be used to apply a force to the card block 443 to drive the card block 443 to slide in the inner cavity of the shell 2 441, and drive the spring 2 442 to contract, so that the card block 443 can be pushed out from the inner cavity of the limiting groove 12, and then the position limitation of the sampling structure 4 by the second limiting structure 44 is released, and then under the elastic force of the spring 3 6, the sampling structure 4 will be pushed to slide in the inner cavity of the protective block 1, thereby driving the slider 1 42 to slide in the inner cavity of the slide groove 11, and then the sample chamber structure 43 will move toward the cement direction, so that the sample chamber structure 43 can be inserted into the bagged cement by using the spring 3 6, and during the sliding process of the connecting plate 2 41, the operating rod 45 will be driven to slide in the inner cavity of the connecting rod 51;

[0054] After the sample chamber structure 43 is deeply inserted into the cement, the connecting rod 51 is operated to rotate, so that the connecting rod 51 can be used to drive the operating rod 45 to rotate, and then the operating rod 45 is used to drive the blocking tube 433 to rotate in the inner cavity of the connecting groove 432, so that the blocking of the sampling port of the sampling tube 431 can be released, and then the cement sample will flow into the inner cavity of the sampling tube 431 through the sampling port of the sampling tube 431, so that the cement sample is sampled by the sampling tube 431, and then the connecting rod 51 is operated to rotate, and then the connecting rod 51 is used to rotate. The rod 51 drives the operating rod 45 to rotate, so that the operating rod 45 can be used to drive the blocking tube 433 to reset, and then the blocking tube 433 is used to close the sampling port of the sampling tube 431 to prevent other layers of cement from flowing into different sample storage chambers when the sampling structure 4 is taken out of the cement, thereby affecting the quality of subsequent detection. When the sampling structure 4 completes sampling, the sampling structure 4 is taken out of the cement, and then the sampling structure 4 is reset. By resetting the sampling structure 4, other structures can be driven to reset.
