[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-6 A sampling device for food safety detection is shown, including a weekly self-sampling mechanism and a cleaning intelligent controller 002. The weekly self-sampling mechanism includes an air suction support box 101, an air guide square tube 102, and an air suction powder intercepting box 103. The air suction powder intercepting box 103 is located between the air suction support box 101 and the air guide square tube 102. The air guide square tube 102 is configured to be L-shaped, and the end of the air guide square tube 102 close to the air suction powder intercepting box 103 is configured to be sealed, and the end away from the air suction powder intercepting box 103 is configured to be open. An air suction fan 104 is fixedly installed in the air suction support box 101. It is connected with a connecting pipe 105, and a sliding support plate 106 is arranged below the powder suction and intercepting box 103. A plurality of sampling boxes 107 evenly distributed along a straight line are movably arranged on the sliding support plate 106, and a box pushing cylinder 108 is fixedly installed on the sliding support plate 106. A linkage component is also arranged on the sliding support plate 106, and the linkage component includes a plurality of box frames 301 which are movably mounted on the plurality of sampling boxes 107, and adjacent box frames 301 are fixedly connected by connecting rods, and a pushed plate 302 is fixedly installed on one of the box frames 301, and the output end of the box pushing cylinder 108 is against the pushed plate 302.

[0020] See also Figure 1-5A sample drop hole 109 is provided on the outer wall of the air guiding square tube 102, a powder blocking hole 110 is provided on the outer wall of the suction guiding powder blocking box 103 away from the connecting tube 105, and a matching interception net 111 is fixedly installed in the powder blocking hole 110. A sampling hole 112 matching the sample drop hole 109 is provided on the top of the sampling box 107, and an air guiding hole 113 matching the powder blocking hole 110 is provided on the side wall of the sampling box 107. One of the sampling boxes 107 is located directly below the sample drop hole 109, and the sampling box 107 is slidingly and sealingly connected to the air guiding square tube 102 and the suction guiding powder blocking box 103. The air guiding square tube 102 is fixedly connected to the suction guiding powder blocking box 103 through a connecting rod 114, and the sliding support plate 106 is fixedly connected to the suction support box 101 through a connecting plate 115. An exhaust hole 116 is provided on the outer wall of the suction support box 101 away from the connecting tube 105.

[0021] See also Figure 6 The cleaning intelligent controller 002 is provided with a sampling control module and a box pushing control module. The sampling control module is connected to the suction fan 104 and the box pushing control module by signal. The box pushing control module is connected to the box pushing cylinder 108 by signal. The cleaning intelligent controller 002 is also provided with a cycle setting module. The cycle setting module is connected to the sampling control module by signal. Those skilled in the art can set the sampling cycle and other related parameters through the cycle setting module.

[0022] The sampling device is installed next to the conveyor belt for conveying corn starch, and one end (the open end) of the air-guiding square tube 102 away from the suction and powder-blocking box 103 is directly above the conveyor belt. The intelligent controller 002 will control the self-sampling mechanism to sample the corn starch on the conveyor belt once every period of time. Each time sampling is performed, the sampling control module will start the suction fan 104 to provide suction force. This suction force can act on the corn starch under the transmission of the connecting tube 105, the suction and powder-blocking box 103, the powder-blocking hole 110, the air-guiding hole 113, the sampling hole 112, the sampling hole 109, the air-guiding square tube 102, etc., so that the corn starch is sucked into the sampling box 107. The interception net 111 will intercept the corn starch to prevent the corn starch from entering the suction and powder-blocking box 103. After a certain period of time, the sampling control module will turn off the suction fan 104 and wait for a certain period of time for the floating corn starch to sink. After that, the sampling control module will send a signal to the box pushing control module. After receiving the signal, the box pushing control module will start the box pushing cylinder 108, so that the box pushing cylinder 108 pushes the pushed plate 302, thereby driving all the sampling boxes 107 to move forward together until the next empty sampling box 107 is pushed to the bottom of the sampling hole 109. In this way, one sampling can be completed. The cleaning intelligent controller 002 will periodically control the weekly self-sampling mechanism to perform the above operations, so that the corn starch can be sampled automatically and periodically. Therefore, through the joint setting of the weekly self-sampling mechanism and the cleaning intelligent controller 002, the cleaning intelligent controller 002 can automatically and periodically control the weekly self-sampling mechanism to sample the corn starch transported on the conveyor belt, without manual sampling. It is not only very convenient and intelligent, but can also effectively reduce the workload of staff and reduce labor costs. It can also prevent samples from being contaminated, thereby improving the accuracy of detection.

[0023] See also Figure 1-2 A pair of side sealing plates 117 matching the sampling hole 112 are fixedly installed on the sampling box 107, and a pair of top sealing plates 118 matching the air guide hole 113 are fixedly installed on the suction powder blocking box 103. The side sealing plates 117 and the top sealing plates 118 can respectively seal the sampling hole 112 and the air guide hole 113 to prevent the sample from being contaminated. A connecting sleeve matching the output end of the pushing box cylinder 108 is fixedly connected to the side of the pushed plate 302 close to the pushing box cylinder 108. The connecting sleeve is movably sleeved on the output end of the pushing box cylinder 108, which can improve the stability of the pushing box cylinder 108 when pushing the sampling box 107.

[0024] The second implementation method: Figure 7-10A sampling device for food safety detection is shown. Different from the first embodiment, a cleaning control module is also provided in the cleaning intelligent controller 002. The sampling device also includes an adjusting cleaning mechanism. The adjusting cleaning mechanism includes a support frame 401 fixedly installed on the top of the suction support box 101, a blowing support box 402 is fixedly installed on the support frame 401, and a blowing fan 403 is fixedly installed in the blowing support box 402. The bottom end of the blowing support box 402 is connected to a blowing pipe 404, and the bottom end of the blowing pipe 404 is connected to the connecting pipe 105. The support frame 401 is set to an L shape, and an electric The magnetic valve 119 and the blow pipe 404 are located on the side of the solenoid valve 119 away from the suction support box 101. An suction hole 407 is opened on the side wall of the blowing support box 402. The suction hole 407 is located above the blowing fan 403. The regulating and cleaning mechanism also includes a support platform 405 arranged below the suction support box 101. A driving motor 406 is fixedly installed on the top of the support platform 405. The output end of the driving motor 406 is fixedly connected to the suction support box 101. The pushing box control module and the cleaning control module are signal-connected. The cleaning control module and the blowing fan 403, the support platform 405, and the solenoid valve 119 are all signal-connected.

[0025] Each time sampling is performed, after the box-pushing cylinder 108 pushes the next empty sampling box 107 to the right below the sample-dropping hole 109, the box-pushing control module sends a signal to the residual cleaning control module. After receiving the signal, the residual cleaning control module starts the driving motor 406, so that the driving motor 406 drives the suction support box 101, the air guide square tube 102, etc. to rotate a certain angle, so that the air guide square tube 102 is away from the conveyor belt, and then the residual cleaning control module closes the solenoid valve 119 and starts the blowing fan 403, so that the blowing fan 403 provides a blowing force, under the action of the blowing force, the interception net 111 and the air guide square tube 102 can be removed. The residual corn starch in the tube 102 is cleaned out. After a certain period of time, the residual cleaning control module will turn off the air blowing fan 403 and open the solenoid valve 119, and then the residual cleaning control module will control the driving motor 406 to drive the suction support box 101, the air guide square tube 102, etc. to rotate and reset. Therefore, by adjusting the setting of the residual cleaning mechanism, after each sampling is completed, the residual cleaning mechanism will be adjusted under the control of the cleaning intelligent controller 002 to automatically clean the residual corn starch on the intercepting net 111 and the air guide square tube 102, thereby improving the accuracy of sampling, and further improving the accuracy of detection.

[0026] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
