Preferably, the sample divider is made of a transparent material.
The staff can conveniently and directly observe and know the internal conditions of the sample divider, such as the capacity use condition of the top sealing cylinder 8 and the material receiving cup 4.
Preferably, the sample divider is made of polycarbonate.
The polycarbonate material has the advantages of high and low temperature resistance, impact resistance, no color, transparency, no toxicity, light weight and the like, and is particularly suitable for being used as a manufacturing material of a sample divider which is directly contacted with grain and oil samples.
Preferably, the feeding hopper 1 is in a conical funnel-shaped structure, the blanking cylinder 2 is a cylinder, the sample separating cylinder 3 is a cylinder with a conical funnel-shaped structure at the bottom, and a containing cavity formed by separating the separating plates 7 is in a fan-shaped column shape;

Preferably, the outer part of the receiving cup 4 is in a truncated cone shape with the diameter decreasing from bottom to top.
The following describes the application process by taking a sample divider provided with two sets of blanking cylinders 2 and sample dividing cylinders 3 as an example:
the method comprises the steps of firstly, splicing and installing and fixing a feeding hopper 1, a first blanking barrel 2, a first sample dividing barrel 3, a second blanking barrel 2, a second sample dividing barrel 3 and a receiving cup 4 from top to bottom in sequence, enabling the bottom of the feeding hopper 1 to extend into the first blanking barrel 2 from an opening at the top of the first blanking barrel 2, and enabling a discharging hole 6 to be communicated with the opening at the top of the first sample dividing barrel 3 through the first blanking barrel 2; simultaneously, the tapered structure narrowed at the bottom of the first sample dividing cylinder 3 stretches into the second blanking cylinder 2 from the opening at the top of the second blanking cylinder 2, and the opening at the bottom end of the sample dividing cylinder 3 is communicated with the opening at the top of the second sample dividing cylinder 3 through the second blanking cylinder 2; the tapered structure of the bottom of the second sample separating cylinder 3 is formed by extending a collecting opening formed at the top of the collecting cup 4 into the collecting cavity, so that an opening at the bottom end of the second sample separating cylinder 3 is communicated with the collecting cavity.
And secondly, pouring grain and oil samples into the feeding hopper 1 through the feeding port 5, and naturally falling the grain and oil samples into the first blanking barrel 2 through the discharging hole 6 positioned right above the central shaft of the first sample separating barrel 3 after the grain and oil samples are collected through the funnel-shaped structure of the feeding hopper 1.
Thirdly, the center shafts of the discharge hole 6 and the first sample separating cylinder 3 are opposite to each other, so that grains and oil samples naturally falling from the discharge hole 6 can be ensured to fall into four cavities of the first sample separating cylinder 3 through the first blanking cylinder 2 in a dispersing way as uniformly as possible;
wherein, the grain and oil samples falling into a pair of top sealing cylinders 8 of the first sample dividing cylinder 3 are separated and collected in the pair of top sealing cylinders 8, and the grain and oil samples falling into a pair of top discharging cylinders 9 of the first sample dividing cylinder 3 fall into the second blanking cylinder 2 from an outlet at the bottom end of the first sample dividing cylinder 3.
Fourthly, the outlet at the bottom end of the first sample dividing cylinder 3 is opposite to the central shaft of the second sample dividing cylinder 3, so that grains and oil samples falling from the outlet at the bottom end of the first sample dividing cylinder 3 can be ensured to fall into four cavities of the second sample dividing cylinder 3 in a dispersed manner as uniformly as possible through the second blanking cylinder 2;
similarly, the grain and oil samples falling into the pair of top sealing cylinders 8 of the second sample separating cylinder 3 are separated and collected in the pair of top sealing cylinders 8, the grain and oil samples falling into the pair of top discharging cylinders 9 of the second sample separating cylinder 3 fall into the receiving cup 4 from the outlet at the bottom end of the second sample separating cylinder 3 until the weight of the grain and oil samples in the receiving cup 4 approaches the weight of the sample required by detection, and the grain and oil samples in the receiving cup 4 are taken as the sample.
In the above experimental process, the staff needs to keep observing the capacity use condition of each pair of top sealing cylinders 8 and receiving cups 4. When the top sealing cylinder 8 is close to full of grain and oil samples, sampling should be suspended, and sampling work is continued after the grain and oil samples in the top sealing cylinder 8 are timely removed. If the capacity of the receiving cup 4 is insufficient to hold a sufficient amount of sample, the "quarter method" sampling of the sufficient amount of sample can be realized by combining the grain and oil samples collected in each receiving cup 4 after multiple sampling.
