[0002] In modern engineering construction work, concrete is one of the most commonly used building materials. It is mainly obtained by mixing gravel, stone powder, cement, water, etc. in a certain proportion. After solidification, it is as hard as rock, also known as concrete. In the production of concrete, different additives and special cements are generally required to adjust the quality of concrete. The quality of concrete is very important, so sampling and testing the concrete before it is put into use is a very important work link in the project.

[0003] A concrete detection sampler disclosed in the announcement number CN217605369U has a simple structure. Because the handle head is threadedly connected to the sample outlet, the sample can be poured out from the sample outlet after the handle head is rotated to separate it from the sampling head.

[0004] However, this concrete detection sampler has the following disadvantages:

[0005] (1) During concrete sampling, it is impossible to crush concrete and collect concrete samples at the same time, which is inconvenient to collect the crushed concrete fragments and increases the workload of the staff;

[0006] (2) When sampling concrete, a large amount of vibration will be generated. If the sampling equipment is not firmly connected, it will cause the sampling to deviate, which will cause the sampling position to change, affecting the accuracy of the sampling. Utility Model Content

[0009] Optionally, the negative pressure assembly includes a negative pressure cylinder sleeved inside the connecting frame, a second driving motor is arranged on the top of the negative pressure cylinder, and an output end of the second driving motor passes through the top of the negative pressure cylinder and is connected to an impeller.

[0010] Optionally, the positioning assembly includes a positioning plate arranged at the bottom end of the leg, a threaded hole is opened on one side of the surface of the positioning plate, the internal thread of the threaded hole is connected to a threaded column for fixing, and the bottom end of the threaded column is provided with a tapered rod for nailing into concrete.
