[0029] The top of the storage box 1 is fixedly connected with a butt joint pipe 9; the position of the butt joint pipe 9 satisfies that when the driving motor drives the plurality of partition sampling boxes 7 to rotate, the feed ports 8 on the plurality of partition plate sampling boxes can pass through the bottom of the butt joint pipe 9 in sequence; the driving mechanism drives the plurality of partition sampling boxes 7 to pass continuously under the butt joint pipe 9, and the sampled grains are stored separately, so that the device can perform continuous sampling operations, and the working efficiency is higher;

[0030] A suction port 10 is provided at the bottom of the plurality of partitioned sampling boxes 7, a sampling air pump 11 is fixedly connected to the bottom of the inner wall of the storage box 1, and a suction pipe 12 is fixedly connected to the air inlet end of the sampling air pump 11, and the position of the suction pipe 12 satisfies that: when the plurality of partitioned sampling boxes 7 are driven electrically to rotate, the suction ports 10 on the plurality of partitioned plate sampling boxes can pass through the top of the suction pipe 12 in sequence; by setting the sampling air pump 11, when sampling, the sample is pumped in the form of a negative pressure formed by the suction, so that the sample can fall into the partitioned sampling box 7 more quickly and stably;

[0031] The outlet end of the sampling air pump 11 is fixedly connected to an outlet pipe 13, and an outlet port 14 is provided at the bottom of one side of the storage box 1, and one end of the outlet pipe 13 is fixedly connected to one side of the outlet port 14;

Gasket 27, airtight gasket 18 located in the air suction port 10, has a material separation net fixedly connected therein; by setting the air suction seal, the butt joint pipe 9 and the air suction pipe 12 are ensured to be stably connected to the separated sampling box 7 during the sampling operation, and the sealing sleeve 16 is pushed to move by the push spring so that its bottom end extends into the air suction port 10 (or the feed port 8), and at the same time, the butt joint gasket 27 is fitted with the airtight gasket 18, thereby improving the air tightness and ensuring the stable suction force of the sampling air pump 11 on the grain sample;

[0033] Arc grooves are provided at the top and bottom of the partition sampling box 7, and the feed port 8 and the air extraction port 10 are both arranged in the arc grooves. The bottom end surface of the sealing sleeve 16 is arranged in an arc shape and slides with the inner wall of the arc groove. By providing the arc groove, the obstruction of the sealing sleeve 16 to the rotation of the partition sampling box 7 is reduced, and at the same time, the stable docking of the air extraction port 10 and the feed port 8 with the sealing sleeve 16 is ensured;

[0034] The sampling part includes a sampling shovel, and the sampling shovel includes an inner shovel head 19 and an outer shovel head 20. Both the outer shovel head 20 and the inner shovel head 19 are configured as semi-cylindrical shapes with pointed cones at the ends, and the inner shovel head 19 is configured inside the outer shovel head 20; one end of the outer shovel head 20 is fixedly connected to a sampling sleeve 21, and one end of the inner shovel head 19 is fixedly connected to a guide tube 22, one end of the guide tube 22 passes through the inside of the sampling sleeve 21 and is fixedly connected to the middle part of an operating tube 23, the diameter of the operating tube 23 is larger than the diameter of the sampling sleeve 21, and one end of the sampling sleeve 21 is stably fitted with one end of the operating tube 23; by arranging the inner shovel head 19 inside the outer shovel head 20, and making the inner shovel head 19 fixed and the outer shovel head 20 rotatable, the inner shovel head 19 and the outer shovel head 20 can enclose and form a sampling cavity, so that the sample amount of each sampling is basically the same, which is convenient for subsequent detection and separation;

[0035] One end of the operating tube 23 is fixedly connected to the docking tube 9 through an adjusting hose 24, and the adjusting hose 24 is configured as a retractable hose; by configuring the adjusting hose 24, the sampling piece can move freely within a certain range, which is convenient for operators to use;

At the same time, since the volume of the marking balls is much larger than the volume of the sampled grain particles, the pushing force it receives during the suction operation is much greater than that of ordinary grain particles. Therefore, the marking balls have higher inertia and impact force when moving in each pipeline, thereby achieving the pushing and cleaning of the grain samples, effectively reducing the probability of grain accumulation in the pipeline.

[0037] The working principle of the present invention is as follows: the device is pushed to the vicinity of the grain sample to be sampled, the operator takes the operating tube 23, inserts the sampling shovel into the grain, and then rotates the sampling sleeve 21 to drive the outer shovel head 20 to rotate, so that the inner shovel head 19 and the outer shovel head 20 are mutually enclosed to form a sampling cavity, and the grain to be sampled in the sampling cavity is encapsulated, and then the operator extracts the sampling shovel from the grain and lifts it vertically upward, so that the sampled grain falls along the guide tube 22, the operating tube 23, and the adjustment hose 24;

[0038] After the obtained sample passes through the operating tube 23, open the storage box 25, take out the appropriately marked marking ball, open the closing plate 26, and put the marking ball into the operating tube 23 through the air inlet pipe; at this time, the sampling air pump 11 starts to drive the marking ball and the grain sample to fall into the separated sampling box 7; when the marking ball and all grain samples enter the separated sampling, the sampling air pump 11 stops working and one sampling is completed.

[0039] After one sampling is completed, the driving motor 5 is started, driving the driving turntable 6 and the partitioned sampling box 7 to rotate until another empty partitioned sampling box 7 is docked with the docking tube 9 and the suction seal on the suction tube 12;

[0040] When all sampling operations are completed, the sampling plate is pulled to move the driving pad 2 together with a plurality of partitioned sampling boxes 7 out as a whole.
