[0025] As shown in the figure: a grain unmanned laboratory described in the present invention includes a sampling system 1, a detection system 2, a sample retention system 3, a central control cabinet 4 and a computer 5. The sampling system 1 includes a sampler 101, an electric screen 102 and a sample divider 103 connected in sequence. The detection system 2 includes a detector 201 and an output mechanism 202 for outputting samples flowing out of the detector 201. The sample retention system 3 includes a collection bucket 301, an automatic packaging mechanism 302 connected to the collection bucket 301 and an automatic spray device 303 connected to the automatic packaging mechanism 302, and also includes a self-moving distribution system 6 for receiving the sample divider 103 and distributing the sample to the collection bucket 301 and the detector 201. The detector 201, the output mechanism 202 and the material distribution system are connected to the central control cabinet 4 for controlling the operation of the equipment and the computer 5 for data and signal interaction. The automatic packaging mechanism 302 and the automatic spray device 303 are connected to the computer 5. The automatic packaging mechanism 302 preferably selects a filling and packaging integrated machine, and the output mechanism 202 preferably selects a screw conveyor. Preferably, the self-moving distribution system 6 includes a slide rail 601, a trolley 602 moving along the slide rail 601, a bucket 604 provided on the trolley 602, a discharge pipe provided on the bucket 604 and connected with the bucket 604, and a controller of the trolley 602 (not shown in the figure), a position sensor 7 is provided at one end of the slide rail 601, a dosing device 603 is provided at the discharge pipe, the dosing device 603 is connected to the controller of the trolley 602, the position sensor 7 is connected to the central control cabinet 4, and the controller of the trolley 602 is connected to the central control cabinet 4 in a wired or wireless manner. Of course, the self-moving distribution system 6 can also be a device with a similar self-moving distribution function.

[0026] When in use, the sampling tube extracts the grain to be inspected in the vehicle to the electric screen 102, and the electric screen 102 is smashed to form a sample to be inspected. The sample to be inspected enters the sample divider 103 through the discharge port of the electric screen 102 to distribute the sample to the bucket 604. The trolley 602 carries the sample in the bucket 604 for a distance and stops above the detector 201. After stopping for a certain period of time, the controller of the trolley 602 controls the quantitative device 603 to quantitatively distribute the sample in the bucket 604 to the detector 201. Here, the detector 201 can be a combination of one or more of a gas detector 2011, a three-grain detector 2012, a pest detector (not shown in the figure), and a moisture detector 2014. The detector 201 is a prior art, and the corresponding detector transmits the detection data and results to the computer 5. The trolley 602 continues to move to the top of the collection bucket 301, and quantitatively distributes the samples to the collection bucket 301. The samples in the collection bucket 301 enter the filling and packaging integrated machine under the action of their own gravity, and the filling and packaging integrated machine automatically packages the samples. The packaged samples are sprayed with corresponding information, such as key test indicators and vehicle information or qualified or not, by the automatic spray device 303 controlled by the computer 5 on the workbench of the filling and packaging integrated machine, for comparison of results in later spot checks.

[0027] In order to ensure that the trolley 602 stops accurately, each time before the next operation, the trolley 602 moves from one end of the track to the position sensor 7. After each operation, it returns to the position and is detected by the position sensor 7. In the next operation, the accumulated motion error is avoided to ensure the accurate stopping position of the trolley 602.

[0028] Preferably, in order to increase the closedness of the present invention, a laboratory is also added in this embodiment. The laboratory includes a sample chamber, a detection chamber, a sample retention chamber and a dustproof partition, the sample chamber 8 is located at the upper part of the dustproof partition 15, the detection chamber 9 and the sample retention chamber 10 are located at the lower part of the dustproof partition 19, and the self-moving distribution system is located at the lower part of the dustproof partition 18 and placed at the upper part of the detection chamber 9 and the sample retention chamber 10; the sampling system 1, the detection system 2, and the sample retention system 3 are respectively arranged in the sample chamber 8, the detection chamber 9 and the sample retention chamber 10, and the dustproof partition 18 is provided with a guide pipe 104, and the upper end of the guide pipe 140 is connected to the sample divider 103 and the lower end penetrates and is connected to the dustproof partition 18. The present invention not only simplifies the structure by reasonably arranging the sampling system 1, the detection system 2, and the sample retention system 3, and reasonably designing the connection relationship between the systems, but also realizes that the sample feed port and the cheating equipment are all enclosed in the laboratory. Therefore, the present invention realizes unmanned operation and enhances the anti-cheating effect. Secondly, the dustproof partition 18 can be used to fix the track of the vehicle and is connected to the detection chamber 9 through a guide pipe 104 and has a compact structure with few openings, which can ensure that the grain in the sample divider can smoothly enter the bucket. The opening of the dustproof plate can be reduced, and the grain is effectively prevented from contaminating the detection system 2 and the sample retention system 3 when the electric screen 102 removes impurities.

[0029] Furthermore, it also includes a display 11 and a printer 12 connected to the computer 5 for displaying the test data and printing the test results, respectively, and the display 11 and the printer 12 are arranged outside the laboratory. Of course, a rainproof shield (not shown) is provided at the printer.

[0030] In this embodiment, the electric screen 102 is provided with a fan 1021 and a debris removal port, and the first electric valve 1022 is provided at the debris removal port, and the first electric valve 1022 is connected to the slide pipe. The fan 1021 and the debris removal port can timely remove the impurities to prevent them from being retained in the electric screen 102 and preventing them from affecting the next detection result.

[0031] At present, there are quantitative and non-quantitative samplers 101 on the market. In order to enrich and improve the usability of the present invention, in this embodiment, the lower end of the sample divider 103 is provided with a first sample outlet (not shown in the figure) for outputting excess materials, and the first sample outlet is provided with a second electric valve 1031, and the second electric valve 1031 is connected to a material delivery pipe 1032, and the outlet end of the material delivery pipe 1032 is connected to a material temporary storage box 13. The second electric valve 1031 of the first sample outlet can discharge the excess sample in the sample divider 103 to facilitate the use with ordinary samplers 101 on the market. Further, the slide pipe and the output mechanism 202 are connected to the material temporary storage box 13, and the material temporary storage box 13 is connected to a return pipe 14, and a vacuum pump 15 is provided in the return pipe 14. The discharge end of the return pipe 14 is located at the upper part of the car, and the vacuum pump 15 is electrically connected to the central control cabinet 4. After the excess sample enters the material temporary storage box 13, the vacuum pump 15 and the return pipe 14 can return it to the vehicle.

[0032] A grain testing method comprises the following steps:

[0033] S1: Use the sampler 101 to take a fixed or unfixed amount of food in the vehicle into the electric sieve 102 for standby use;

[0034] S2: Control the electric sieve 102 to deliver the cleaned sample to the sample divider 103, and the sample divider 103 distributes the sample to the self-moving trolley 602;

[0036] S4: The detector 201 interacts with the computer 5 and outputs the test results to the display screen. The sample retention system 3 retains the sample for comparison of the results in the subsequent spot check.

[0037] S5: After the detection is completed, the detector 201 and the excess samples in the trolley 602 are output to the laboratory using the output mechanism 202 to prepare for the next detection.

[0038] In this embodiment, a fingerprint lock 17 is set on the door 16 of the laboratory in S5, and the fingerprint lock 17 is connected to the computer 5, and the fingerprint information is used to record the information of the personnel entering and leaving the laboratory to form a complete quality control information. Even after the sample is taken away, the information of the sampler can be tracked and checked.

[0039] The grain testing method of the present invention has strong equipment and information closure, which greatly improves the difficulty of cheating and reduces the probability of favoritism. In addition, the existing mature fingerprint lock 17 function is combined with the sample tracking function to greatly save costs, and the information flow is closed and complete.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
