[0003] The prior art patent publication number CN220894107U describes a rapid screening device for dried agricultural products from both northern and southern China. This patent includes a main body with a control panel and a discharge port on its front side. A monitoring window is located to the right of the discharge port. The main body is mounted on a frame and utilizes two opposing pressure detectors. When a packaged bag passes through, a movable pressure sensor moves upward, generating a pressure reading. Conversely, when a leaky or completely leaky package passes through this pressure detector, the reading is lower than that of a properly packaged one, thus detecting and distinguishing between intact and leaky packaging. However, in practical use, this patent has the following shortcomings: In practice, when unqualified packaging is detected, it requires a push plate to remove the package from the conveyor belt, necessitating a stop in the conveyor belt. This reduces the efficiency of product detection and hinders convenient sorting and transport of qualified and unqualified packaged goods, thus complicating subsequent processing and reducing the device's practicality.
[0004] Therefore, there is a need for a rapid screening device for dried agricultural products to solve the problems in existing technologies where the screening process affects transportation efficiency and makes it inconvenient to conveniently classify and transport packaged goods that have passed and failed the test.

[0021] The present invention will be further described below with reference to the embodiments.
[0022] Please see Figure 1-4This utility model provides a rapid screening device for dried agricultural products, including a mounting frame 1, a conveying device 2, and a screening box 3. The conveying device 2 is mounted on the mounting frame 1, and the screening box 3 is mounted above the conveying device 2 via the mounting frame 1. A feeding plate 4 is fixedly connected to the right side of the mounting frame 1, and a partition plate 401 is fixedly connected to the feeding plate 4. A feeding basket 402 is provided on the lower right side of the feeding plate 4, and a collection frame 403 is detachably mounted on the feeding basket 402. A screening mechanism 5 is provided on the screening box 3, and a screening partition 303 is fixedly connected inside the screening box 3, dividing the screening box 3 into two parts. A detection device 6 is provided in the front space inside the screening box 3, and a viewing window 301 is provided on the front surface of the screening box 3. A controller 302 is fixedly mounted on the right side of the viewing window 301 on the screening box 3. The screening mechanism 5 and the detection device 6 are both electrically connected to the controller 302.
[0023] The conveying device 2 and the detection device 6 have been specifically disclosed in the patent with patent publication number CN220894107U, and their related principles and structures will not be elaborated on here.
[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the left side of the screening partition 303 is set as an inclined guide plate, and the right side of the screening partition 303 is matched with the partition plate 401. There are two collection boxes 403 on the feeding basket 402, and the two collection boxes 403 are matched with the partition plate 401 and are separated in front and behind.
[0025] One step like Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the detection device 6 includes a fixed frame 601, which is fixedly installed inside the screening box 3 and located in front of the screening partition 303 and on the left side of the through opening 501. A pressure sensor 602 is fixedly installed inside the fixed frame 601, and a spring 603 is fixedly connected to the pressure sensor 602. A detection plate 604 is fixedly connected to the bottom end of the spring 603, and the detection plate 604 is slidably disposed inside the fixed frame 601.
[0026] In use, the screening partition 303 is set so that the goods can only be conveyed under the detection device 6. When the packaged goods are conveyed under the detection plate 604, they will be squeezed, which will cause the pressure sensor 602 to generate a pressure value through the spring 603. When unqualified packaging is detected, the pressure sensor 602 will generate an abnormal pressure value, thus determining that the packaging is unqualified. Through the conveying device 2, the qualified and unqualified goods are conveyed to the unloading plate 4 through the front and rear sides of the partition plate 401, and then collected by different collection boxes 403, so as to facilitate different subsequent processing operations for different goods and improve the practicality of the device.
[0027] As can be seen from the above working process, the screening partition 303 inside the screening box 3 divides the interior into two conveying spaces. The screening mechanism 5 facilitates the separate conveying of qualified and unqualified goods, and they are collected by different collection boxes 403 to facilitate subsequent processing operations, thus improving the practicality of the device.
[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the screening mechanism 5 includes a through-hole 501, on which a screening baffle 303 is provided and located on the right side of the detection device 6. A movable plate 502 is movably disposed within the through-hole 501, and the movable plate 502 is sized to match the through-hole 501. A rotating shaft 503 is fixedly connected to the top right side of the movable plate 502, and the rotating shaft 503 is rotatably mounted on the screening box 3. An adjustment groove 504 is provided on the upper surface of the movable plate 502, and a roller 505 is slidably disposed within the adjustment groove 504. A connecting block 506 is fixedly connected to the top, and a slide block 507 is fixedly connected to the rear side of the connecting block 506. An installation frame 508 is fixedly connected to the outside of the slide block 507 on the screening box 3. A groove 509 matching the slide block 507 is opened on the inner surface of the installation frame 508. The slide block 507 slides in the installation frame 508 through the groove 509. A maintenance plate 5011 is detachably installed on the top of the installation frame 508. An electric telescopic rod 5010 is fixedly connected to the rear side of the slide block 507. The electric telescopic rod 5010 is fixedly installed in the installation frame 508.
[0029] In use, when unqualified goods are detected during screening, the controller 302 sends a command to the electric telescopic rod 5010 to operate, causing the slide 507 to slide within the mounting frame 508. This, in turn, causes the connecting block 506 to move the roller 505. Since the roller 505 is slidably set within the adjusting groove 504, the roller 505 pushes the movable plate 502 to rotate via the rotating shaft 503 during its movement. This causes the movable plate 502 to rotate within the through opening 501, opening the through opening 501. The movable plate 502 also acts as a guide, directing the unqualified goods to the space behind the screening partition 303 for transport via the conveying device 2. After completion, the system is restored to its original state, and the screening work continues.
[0030] This solution has the following working process: When this device is in use, the goods are conveyed to the screening box 3 by the conveying device 2 for screening. The screening partition 303 ensures that the goods can only be conveyed below the detection device 6. When the packaged goods are conveyed below the detection plate 604, they will compress the detection plate 604, causing the pressure sensor 602 to generate a pressure value through the spring 603. When unqualified packaging is detected, the pressure sensor 602 will generate an abnormal pressure value, thus determining that the packaging is unqualified. At this time, the controller 302 sends a command to the electric telescopic rod 5010 to operate, causing the slide 507 to slide within the mounting frame 508, which in turn causes the connecting block 506 to drive the roller 505 to move. The shaft 505 is slidably installed in the adjusting groove 504, so that the roller 505 pushes the movable plate 502 to rotate through the rotating shaft 503 during the movement of the roller 505. This causes the movable plate 502 to rotate in the through opening 501, opening the through opening 501. The movable plate 502 also acts as a guide, guiding the unqualified goods to the space behind the screening partition 303, where they are transported by the conveying device 2. After completion, the original position is restored, and the screening work continues. Through the conveying device 2, qualified and unqualified goods are discharged onto the feeding plate 4 through the front and rear sides of the partition plate 401, and then collected by different collection frames 403, so as to facilitate different subsequent processing operations for different goods and improve the practicality of the device.
[0031] In summary: The screening mechanism 5, in conjunction with the detection mechanism 6, can conveniently and quickly screen and transport unqualified packaged goods. The screening process does not affect the conveying efficiency of the conveying device 2, thereby improving the goods conveying efficiency and screening efficiency. The screening partition 303 inside the screening box 3 divides it into two conveying spaces. The screening mechanism 5 facilitates the separate transport of qualified and unqualified goods, which are then collected by different collection boxes 403 for subsequent processing, thus improving the practicality of the device.
