Therefore, an improved sample dividing device is needed, which can change the grain flow trajectory many times, mix the grain particles with different specific gravities more uniformly, and divide the sample more representatively. The improved sample dividing device has very important practical significance for solving the quality inspection disputes in the critical state, calming the customers' emotions, improving the work efficiency and reducing the labor intensity. However, there is no relevant public report so far. SUMMARY

The material collecting barrel is arranged above the dustproof bin. A mixing bin and a separating bin are sequentially arranged below the dustproof bin and are connected with each other. The mixing bin and the separating bin are respectively provided with a mixing bin door and a separating bin door through hinges. A plurality of sample dividers are arranged in the mixing bin and the separating bin in a vertically connected manner. Each sample divider is arranged in the mixing bin and the separating bin through a slide. The sample dividers in the separating bin are arranged in a staggered manner in the vertical direction and are connected with the outside through a first inclined groove and a second inclined groove. Two receivers are arranged below the lowermost sample divider in the separating bin.
