TECHNICAL FIELD

[0001] The present application relates to the technical field of grain sample preparation, in particular to a grain quantitative sample preparation device. BACKGROUND

[0002] Mixing and subsampling sample preparation machine: a device for mixing and subsampling grain samples into three quantitative small samples. Currently, there are three methods for mixing and subsampling sample preparation on the market: 1. Before or after mixing, the sample is weighed or measured to a certain mass or volume, and then subsampled to obtain n quantitative small samples; 2. After mixing, the sample is weighed and calculated to obtain a quantitative small sample after N times of subsampling; 3. After mixing and subsampling, a medium sample is obtained, which is weighed or measured to obtain a quantitative small sample. Methods 1 and 3 are generally considered to be disturbed during the mixing and subsampling process because of the weighing or measuring process, and the sample is not representative.
