[0015] A method for detecting selenium-enriched rice, comprising the following steps:

[0016] Step 1: Sampling;

[0017] Insert the sampling tube into the rice sample to be sampled, adjust the insertion depth of the sampling tube according to the test requirements, then rotate the rotating baffle to open the sampling port and perform layered sampling of the rice;

[0018] Step 2: Divide the materials;

[0019] Insert the sampling tube after sampling in step 1 into the discharge bin, rotate the rotating baffle again, pour the rice out from the sampling port, and transport each layer of rice separately through the corresponding feeding pipe;

[0020] Step 3: Scrape flat;

[0021] The push plate is pulled to move the rice transported to the feeding pipe in step 2 into the storage box for inspection, and then the push plate is released. The spring restoring force drives the push plate to return to its original position, thereby flattening the upper surface of the storage box.

[0022] Step 4: Sample delivery;

[0023] The motor rotates under the action of the transmission connection of the pulley transmission component 2, driving the gear 2 to rotate, so that the gear 2 and the gear 3 are meshed and connected, and the rotating table rotates. At the same time, the electric push rod pushes the support plate, so that the two sets of friction plates are engaged, thereby rotating the shaft 3. Under the action of the transmission connection of the pulley transmission component 1, the gear 1 and the half gear are meshed and connected, driving the shaft 1 to rotate, thereby driving the material storage box to rotate and transport the rice sample to be tested in step 3;

[0024] Step 5: Rotation detection;

[0025] When the half gear rotates half a circle to disengage, one set of the storage box and the rotating table are magnetically attracted by the magnet. At this time, the electric push rod retracts, the two sets of friction plates are disengaged, and the rotating table rotates independently, thereby driving the storage box to rotate at a uniform speed. The rice is detected by the near-infrared detection instrument as a whole, and the rice is detected while rotating.

[0026] Step 6: Sample discharge;

[0027] After the detection is completed, the electric push rod 2 is driven to move, so that the blocking plate is flipped under the action of the meshing connection between the gear 4 and the rack plate, thereby discharging the rice sample after the detection in step 5.

[0028] Compared with the prior art, the present invention has the following advantages: the provision of the sampling port and the partition facilitates layered sampling of the sampling tube; the provision of the feeding pipe facilitates the control of rice feeding, facilitates the separate delivery of rice at each layer to the storage box, and facilitates batch testing; and the provision of the blocking component facilitates the leveling of the rice, facilitates testing, is simple to operate, and facilitates continuous testing by testing personnel;

[0029] By setting up the synchronous driving components and engaging the two sets of friction plates, it is easy to drive the rotating table and the feeding plate to rotate. The rotation of the feeding plate facilitates the transportation of rice inside the storage box, facilitating the continuous detection operation. By releasing the engagement of the two sets of friction plates, the rotating table rotates independently, thereby facilitating the independent driving and rotation of the storage box moved above the rotating table, facilitating the uniform detection of rice and improving the detection rate.

[0030] The setting of the flip opening and closing parts makes it easy to discharge the rice in the storage box, which is convenient for the inspection of the next batch of rice. The setting of the collecting box makes it easy to collect the rice. The setting of the storage trough allows the operator to choose whether to store the rice in a classified manner or in a centralized manner.

[0031] By setting up the blocking component and pulling the push plate, the rice inside the feeding pipe can be transported to the storage box for testing. When the blocking plate is opened, the remaining rice inside the feeding pipe can be selectively discharged or not to proceed with the next batch of testing. BRIEF DESCRIPTION OF THE DRAWINGS
