[0002] Building materials refer to various materials used in construction projects; there are many types of building materials, which can be roughly divided into inorganic materials, organic materials and composite materials. Witness sampling refers to the sampling or preparation of test pieces on site by professional material testers of the construction unit under the witness of the construction supervision unit or the construction unit. Before the construction of the project, it is necessary to survey and monitor the soil at the construction site to determine the depth of the foundation and the total weight of the building. It is a particularly important task before construction. In order to ensure the safety of materials used in construction projects, ensure the qualification of building materials, and improve the safety of buildings, a small amount of building materials are randomly sampled through a sampler before testing and sampling, and then used for testing to analyze whether the proportion of components is qualified. The sampler is a commonly used tool for testing and sampling.

[0003] There are powder materials in building materials. Since powder materials have a certain fluidity, the existing sampler has an open storage bin during the sampling process. That is, in the process of inserting the sampler into the powder material and pulling it out of the powder material, materials of different depths will enter the storage bin. Therefore, the existing sampler cannot guarantee the accuracy of stratified samples when sampling powder materials. Summary of the invention

The interior of the sampling tube is rotatably connected with an intermediate component, and the inner cavity of the sampling tube is provided with a rotating shaft. The equipment is placed at the position to be sampled, and the hydraulic cylinder is connected to an external power supply to work. The hydraulic cylinder drives the slide plate to move downward, so that the slide plate drives the sampling tube to move downward, and the sampling tube drives the outer spiral plate to move downward. As the spiral plate moves downward, the spiral plate drives the sampling tube to rotate, so that the sampling tube rotates and is inserted into the material, which reduces the damage to the original structure and distribution state of the material due to the insertion action, and ensures that the sample taken can better represent the original state of the material. , which improves the authenticity and reliability of the sample. After the insertion depth is good, the motor is connected to the external power supply to work. The motor drives the rotating shaft to rotate through the connecting assembly, and the rotating shaft drives the cylinder and the extension rod to rotate.
