[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Example: Figure 1 , 2 , 3, 4, 5, and 6, the fixed ratio grain sampler of this embodiment includes a frame 1, a casing 2, a rotation drive device 3, and a centrifugal rotation module 4. The casing 2 is mounted on the upper end of the frame 1, and has a cylindrical cavity 21 inside. The centrifugal rotation module 4 is a ring-shaped component adapted to the cavity 21. The inner cavity of the centrifugal rotation module 4 forms a centrifugal sample separation cavity 41. The centrifugal rotation module 4 is coaxially arranged in the cavity 21, and the axis extends horizontally. A feed port connected to the centrifugal sample separation cavity 41 is provided in the middle of one end of the casing 2. The rotation drive device 3 is mounted on the frame 1. On the top, its driving end passes through the middle of the other end of the above-mentioned casing 2 and is transmission-connected with the above-mentioned centrifugal rotating module 4. The bottom of the above-mentioned casing 2 is provided with a plurality of discharge ports 22 connected with the above-mentioned cavity 21 between its two ends. The above-mentioned centrifugal rotating module 4 is provided with a plurality of groups of discharge channels 42 corresponding to the above-mentioned discharge ports 22 one by one. The two ends of the above-mentioned discharge channels 42 are respectively connected to the above-mentioned centrifugal sample separation cavity 41 and the periphery or edge of the centrifugal rotating module 4. The above-mentioned rotation driving device 3 is used for driving the above-mentioned centrifugal rotating module 4 to rotate, and makes each group of the above-mentioned discharge channels 42 rotate through the above-mentioned discharge port 22 corresponding to the bottom.

[0028] The usage process is as follows:

[0029] A batch of grain samples are put into the centrifugal sample separation chamber 41 inside the centrifugal rotating module 4 through the feed port at one end of the casing 2. Synchronously, the rotary drive device 3 drives the centrifugal rotating module 4 to rotate in the chamber 21 of the casing 2. Since the size of the chamber 21 is close to that of the centrifugal rotating module 4 (the gap between the two is small and the grain samples will not enter), during the rotation of the centrifugal rotating module 4, the grain samples are only introduced when the discharge channel 42 rotates to the port (external port) at the periphery or edge and aligns with the corresponding discharge port 22 below. It will fall through the discharge port 22. Since the number of the discharge ports 22 corresponds to the number of the multiple groups of discharge channels 42, and the rotation and sampling of the grain in the centrifugal sampling chamber 41 is a uniform powder process, the grain sample will be evenly distributed into multiple portions through the inner ports (ports connected to the centrifugal sampling chamber 41) of the multiple groups of discharge channels 42 of the centrifugal rotating module 4. The multiple portions of grain samples fall through the multiple discharge ports 22 respectively, and the quantity of each portion is determined according to the number of each group of discharge channels 42, thereby finally realizing the proportional sampling of the grain sample.

[0030] In this embodiment, the number of each group of the above-mentioned discharge channels 42 is one or more, and the multiple above-mentioned discharge channels 42 in each group are distributed at intervals along the circumference of the above-mentioned centrifugal rotating module 4.

[0031] More specifically, there are four discharge ports 22, and correspondingly, there are four groups of discharge channels 42, and the ratio of the number of the four groups of discharge channels 42 distributed from one end to the other end along the axial direction of the centrifugal rotating module 4 is 6:1:1:2. In this embodiment, the number of the four groups of discharge channels 42 from one end to the other end of the centrifugal rotating module 4 can be set to 6, 1, 1, and 2, so that the volume ratio of the food samples distributed through the four discharge ports is about 6:1:1:2.

[0032] As a preferred embodiment, the two ends of the above-mentioned cavity 21 and the two ends of the above-mentioned centrifugal rotating module 4 respectively form annular cavities, and the outlets of the two groups of the above-mentioned discharge channels 42 located at the two ends are respectively located at the edges of the end surfaces of the two ends of the centrifugal rotating module 4, and the outlets of the remaining two groups of the above-mentioned discharge channels 42 are both located on the outer peripheral surface of the above-mentioned centrifugal rotating module 4.

[0033] In the above embodiment, the two ends of the cavity 21 are set as annular cavities. This structural design makes the outer ports of the two groups of discharge channels 42 located at the two ends designed at the edges of the end faces of the centrifugal rotating module 4, and the outer ports of the two groups of discharge channels 42 located in the middle are on the outer peripheral surface of the centrifugal rotating module 4. In this way, the arrangement of the discharge channels 42 is more reasonable, the outer ports will not be concentrated on the outer peripheral surface of the centrifugal rotating module 4, and the volume can be designed to be miniaturized.

[0034] As a preferred embodiment, each of the above-mentioned discharge ports 22 is connected to a discharge channel 5 at the lower end, and the above-mentioned discharge channels 5 extend downward into the above-mentioned frame 1, and a material receiving box 8 is provided below the lower end channel opening of each of the above-mentioned discharge channels 5.

[0035] In the above embodiment, the multiple grain samples from the discharge port 22 fall into the corresponding material receiving boxes 8 from the discharge channel 5. Specifically, if there are four discharge ports 22, the grain samples are divided into four portions and fall into four material receiving boxes 8. The volume ratio of the grains in the four material receiving boxes 8 can be set to 6:1:1:2 according to the above embodiment, or the number of discharge channels 42 can be changed to define other ratios.

[0036] In this embodiment, the rotation drive device 3 adopts a servo motor or a stepper motor of an appropriate type. Figure 6 As shown, the motor shaft of the rotary drive device 3 is connected to a mounting plate (indicated by b in the figure) through a transmission shaft (indicated by a in the figure), and the mounting plate is coaxially connected to the other end of the centrifugal rotating module 4. Among them, one end of the centrifugal rotating module 4 is coaxially provided with the above-mentioned centrifugal sample separation chamber 41.

[0037] In this embodiment, a plurality of supporting rubber feet 11 are provided at the bottom of the frame 1. The design of the supporting rubber feet 11 makes the entire device more stable when placed on a carrier surface such as a desktop, and is not easy to slip.

[0038] As a preferred embodiment, a grain feeding device 6 is connected to the feed inlet.

[0039] In the above embodiment, the grain feeding device 6 facilitates the feeding of grain samples into the centrifugal sampling chamber 41 .

[0040] As a preferred embodiment, the grain feeding device 6 includes a hopper 61 and a feed pipe 62. The hopper 61 is fixed above one end of the casing 2. One end of the feed pipe 62 is connected to the bottom of the hopper 61, and the other end extends downward and is connected and connected to the feed port.

[0041] In the above embodiment, a valve is provided at the upper end of the discharge pipe 62. When in use, the valve is closed in advance, and a grain sample is loaded into the hopper 61. Thereafter, after starting the equipment (that is, after starting the rotary drive device 3), the valve is opened, and the grain sample in the hopper 61 slides into the centrifugal sampling chamber 41 through the discharge pipe 62 under the action of gravity, and then the subsequent sampling operation is performed.
