AI Technical Summary
Existing grain and oilseed sampling devices often result in uneven sample differentiation when the feed volume is large, affecting the reliability of subsequent testing.
The structure includes a feeding hopper, a dispersion chamber, a conveying channel, and a sample distribution chamber. The sample distribution chamber is equipped with a sample distribution seat and a disperser. The sample distribution seat is equipped with a partition plate and a sample distribution cone. Combined with the disperser and the sample receiving box, the sample is evenly dispersed and the drop speed is reduced.
This method achieves thorough and uniform sample dispersion, reduces the material feeding speed, and ensures the representativeness of the samples and the reliability of subsequent testing.
