[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, four connecting brackets 2 are fixedly connected to the top of the fixed platform 1. The four connecting brackets 2 are symmetrically distributed on the top of the fixed platform 1. Two fixed plates 4 are fixedly connected to the top of the four connecting brackets 2. The two fixed plates 4 are symmetrically distributed on the top of the connecting brackets 2. A first motor 5 is fixedly connected to one side of one of the fixed plates 4. Several connecting rollers 6 are fixedly connected to the opposite sides of the two fixed plates 4. The connecting rollers 6 are arranged in a linear array between the two fixed plates 4.

First, the material to be sampled is placed on the transmission belt 7, and the first motor 5 is started at the same time. The first motor 5 drives the connecting rollers 6. The transmission belt 7 rotates, causing it to rotate and gradually move the material forward. When sampling is required, the sampling component 3 takes the sample.

Simultaneously, the first motor 5 is started, driving the connecting roller 6 to rotate, which in turn drives the transmission belt 7 to rotate, gradually moving the material forward. When sampling is required, it is performed by the sampling component 3. When the material passes the bottom of the sampling component 3, the second motor 312 drives the transmission shaft 308 to rotate. Simultaneously, the transmission shaft 308 drives the hinge shaft 309 to rotate. Then, the hinge shaft 309 drives the fixed rod 310 and the sampling head 311 to sample the material on the transmission belt 7. The sampled material is then collected. The sampling head 311 rotates, and at the same time, the drive motor 313 drives the connecting sliding block 307 to move towards the discharge trough 305. When it moves to the appropriate position, the material from the sampling head 311 is poured into the discharge trough 305, thus completing the material sampling. Installed in the middle of the belt, it can intercept the material across the entire cross section of the belt, avoiding the material segregation problem that may occur with end sampling. It can collect more representative samples, accurately reflect the overall characteristics of the transported material, and provide reliable data for subsequent analysis.
