However, this type of sampler has many parts, a complex structure, and high cost. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a sample splitter, which solves the technical problem of how to make the sample splitter low in cost.

[0006] The objectives of the present utility model can be achieved through the following technical solutions: a sample divider, comprising a feed funnel and a frame, characterized in that it also comprises a sample dividing shell arranged on the frame and a sample dividing core located in the sample dividing shell and capable of rotating, a plurality of discharge pipes being connected to the bottom of the sample dividing shell, the sample dividing core being cylindrical, a sample dividing cavity connected to the feed funnel being provided in the sample dividing core, at least one first discharge port connected to the sample dividing cavity being provided on the left side of the sample dividing core, at least one second discharge port connected to the sample dividing cavity being provided on the right side of the sample dividing core, at least one third discharge port connected to the sample dividing cavity being provided on the circumferential outer side of the sample dividing core, the first discharge port, the second discharge port and the third discharge port being respectively connected to the corresponding discharge pipes.

[0007] During operation, grain enters the sample separation cavity of the sample separation core through the feed funnel, and the sample separation core is driven to rotate by a drive motor. As long as the first, second, and third discharge ports are aligned with the corresponding discharge pipes, the grain will flow out from the first, second, and third discharge ports under the action of its own gravity, and then flow out through the discharge pipe. By controlling the size and number of the first, second, and third discharge ports, the amount of grain flowing out of the first, second, and third discharge ports can be controlled, and the grain can be sampled according to different proportions. The sample separator can complete the material separation by providing the sample separation cavity and discharge ports in the sample separation core.

[0009] In the aforementioned sample divider, the sample dividing housing includes several closely fitting sample dividing rings. The sample dividing rings at both ends are tightened by fasteners to ensure a tight fit and secure connection. The annular partitions are located on one or both sides of the sample dividing rings. This structure allows the sample dividing housing to be processed separately and then integrated into one piece, making it easy to manufacture and reducing processing costs.

[0011] In the above-mentioned sample divider, the first discharge port is in a U shape, penetrates through the circumferential edge of the left partition plate, and the circumferential edge of the left side of the core body is provided with a plurality of left limiting blocks embedded in the U-shaped opening of the corresponding first discharge port, so that the left partition plate is circumferentially positioned with the core body. This structure makes the first discharge port convenient to form, and the core body and the left partition plate are firmly connected.

[0012] In the above-mentioned sample divider, the second discharge port is in a U shape, penetrates through the circumferential edge of the right partition plate, and the circumferential edge of the right side of the core body is provided with a plurality of right limiting blocks embedded in the U-shaped opening of the corresponding second discharge port, so that the right partition plate is circumferentially positioned with the core body. This structure makes the second discharge port convenient to form, and the core body and the right partition plate are firmly connected.

[0013] In the above-mentioned sample divider, the circumferential outer side of the sample dividing core is further provided with at least one fourth discharge port, the third discharge port and the fourth discharge port have a certain interval along the axial direction of the sample dividing core, the third discharge port is close to the left side of the sample dividing core, the fourth discharge port is close to the right side of the sample dividing core, and the fourth discharge port is communicated with the corresponding discharge pipe. The arrangement of the fourth discharge port enables the sample divider to divide the fourth sample, and if necessary, a fifth discharge port, a sixth discharge port and the like can be arranged on the circumferential outer side of the sample dividing core, and only a certain interval along the axial direction of the sample dividing core is needed, so that the discharge ports do not interfere with each other.
