[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0016] A sampling device for cement quality sampling and testing includes: a sampling unit 1, a rotating unit 2, and a storage bottle 3. The sampling unit 1 is rotatably connected to the rotating unit 2, and the storage bottle 3 is screwed to the rotating unit 2. Multiple storage bottles 3 are provided.

[0017] The sampling unit 1 includes: a sampling tube 1-1, a shaft support 1-2, a rotating shaft 1-3, a spiral blade 1-4, a rotating ring 1-5, a rotating ring hole 1-6, and a positioning groove 1-7. The sampling tube 1-1 has an opening at its front end. The shaft support 1-2 is fixed inside the sampling tube 1-1. One end of the rotating shaft 1-3 is rotatably connected to the shaft support 1-2, and the other end of the rotating shaft 1-3 rotatably passes through the sampling tube 1-1. The spiral blade 1-4 is fixed on the rotating shaft 1-3. The rotating ring 1-5 is fixed at the outer end of the sampling tube 1-1. The rotating ring 1-5 is provided with a rotating ring hole 1-6, which is fixedly connected to the sampling tube 1-1. The sampling tube 1-1 is provided with a positioning groove 1-7, which corresponds to the rotating ring hole 1-6.

[0018] The rotating unit 2 includes: a rotating disk 2-1, an annular groove 2-2, a screw-in groove 2-3, a connecting hole 2-4, and an alignment groove 2-5. The sampling tube 1-1 rotates through the center of the rotating disk 2-1. The rotating disk 2-1 is provided with an annular groove 2-2, and the rotating ring 1-5 rotates within the annular groove 2-2. The rotating disk 2-1 is provided with multiple downward-facing screw-in grooves 2-3, each with an internal thread. Multiple storage bottles 3 are screwed into the screw-in grooves 2-3 respectively. The rotating disk 2-1 is provided with multiple connecting holes 2-4, one end of which communicates with the screw-in groove 2-3, and the other end of which communicates with the screw-in groove 2-3. The size of the connecting hole 2-4 matches the rotating ring hole 1-6. The rotating disk 2-1 is provided with multiple alignment grooves 2-5 on its side, each alignment groove 2-5 corresponding to one screw-in groove 2-3.

[0019] The working principle of this utility model is as follows:

[0020] When using this device, multiple storage bottles 3 are screwed into the screw-in grooves 2-3 respectively, and the storage bottles 3 are marked with numbers. Then, the sampling tube 1-1 is inserted into the cement bag. Then, rotating the rotating shaft 1-3 causes the spiral blades 1-4 to rotate, driving the cement upwards. The cement then enters the connecting hole 2-4 through the rotating annular hole 1-6, then enters the screw-in groove 2-3 through the connecting hole 2-4, and finally enters the storage bottle 3 for storage. The annular groove 2-2 limits the rotating annular hole 1-6, thus supporting and limiting the sampling tube 1-1. When the cement stored in the storage bottle 3... After filling, remove the storage bottle 3, reverse the rotation shaft 1-3 to rotate the spiral blade 1-4 and push out the remaining cement in the sampling tube 1-1, thus cleaning the inside of the sampling tube 1-1. Then, hold the sampling tube 1-1 and rotate the rotating disk 2-1 to align the other alignment groove 2-5 with the positioning groove 1-7. At this time, the other engagement groove 2-3 and the connecting hole 2-4 are aligned with the rotating ring hole 1-6. Then, another bag of cement can be sampled in the same way. Multiple bags of cement can be sampled simultaneously in this way without having to go back and forth between the sampling and storage devices. After sampling is completed, remove the storage bottle 3 for testing. By setting the positioning groove 1-7 and the alignment groove 2-5, the rotating ring hole 1-6 can be aligned with the connecting hole 2-4 more quickly and accurately.

[0021] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
