The gyroscope sensor, the driving small turntable 804 and the driving mechanism are respectively connected to the controller. Preferably, the number of the third cylindrical supports 806 is two. In a specific embodiment of the present invention, the gyroscope sensor is used to measure the angular velocity of the support seat 805 and send it to the controller, and the controller controls the rotation of the driving small turntable 804 so that the third cylindrical support 806 maintains a horizontal direction, ensuring the smoothness of the seedling tray transportation process.

[0049] As Figure 3As shown, the width of the second belt 407 is one-third of that of the first belt 406, which not only ensures the smooth transportation of the seedling tray but also facilitates the third cylindrical support 806 of the vertical conveying device 8 to pass through the gap between the first cylindrical support 404, the second driving roller 403, and the second driven roller 405, as Figure 1 shown. As Figure 4 shown, the width of the third belt 507 is one-third of that of the fourth belt 506, which not only ensures the smooth transportation of the seedling tray but also facilitates the third cylindrical support 806 of the vertical conveying device 8 to pass through the gap between the second cylindrical support 504, the fourth driving roller 503, and the fourth driven roller 505, as Figure 7 shown.

[0051] The controller is a PLC.

[0052] The utility model monitors the sowing accuracy rate of the seedling tray through the camera 702 and the controller. Ideally, one rice seed is sown in each cell of the seedling tray. If the accuracy rate is lower than the preset value, the unqualified seedling trays are screened out by the vertical conveying device 8 and transported to the third horizontal conveying device 6 for manual assistance, and the qualified seedling trays are transported to the second horizontal conveying device 5 for seedling raising, which improves the accuracy of the entire sowing flow operation and reduces the difficulty of the seedling raising work.

[0053] The working process of the seedling tray screening and transporting device of the utility model is as follows:

[0054] After the seeder finishes sowing on the seedling tray, the seedling tray screening and transportation device downstream of the seeder is entered. First, it enters the first frame 1. The first belt 406 of the first transverse conveying device 4 transports the seedling tray to the end of the second belt 407. The camera 702 of the detection device 7 takes a photo of the seedling tray and transmits it to the controller. The controller checks whether the sowing accuracy rate of the seedling tray exceeds the preset value based on the picture. If it does not exceed the preset value, it is qualified; if it exceeds the preset value, it is unqualified. If it is qualified, the controller controls the second belt 407 to transport the seedling tray to the third belt 507 of the second transverse conveying device 5 to wait for seedling cultivation. If it is unqualified, the controller controls the active loading plate 801 of the vertical conveying device 8 to start rotating. The fifth belt 803 drives the third cylindrical support 806 to pass through the gap between the first cylindrical support 404, the second driving roller 403, and the second driven roller 405, lifting the seedling tray on the second belt 407. The gyroscope sensor measures the angular velocity of the support seat 805 and transmits it to the controller. The controller controls the active turntable 804 to rotate, so that the third cylindrical support 806 remains in the horizontal direction, ensuring the smoothness of the seedling tray transportation process.

[0055] When the seedling tray rises to the third transverse conveying device 6, the third transverse conveying device 6 transports the seedling tray on the third cylindrical support 806 to the rear, waiting for manual assistance to sort out the number of sowing grains on the seedling tray.
