A air supply mechanism is installed at the top of the feeding tray 2 near each placement hole 9, a stepper motor 26 is fixedly installed on the top wall of the support platform 1, and the output end of the stepper motor 26 penetrates the top end of the support platform 1 and is fixedly installed with the rotation center of the feeding tray 2.

[0020] In this embodiment, the air supply mechanism includes a support plate 11 fixedly installed at the top end of the feeding tray 2. A chute 15 is formed through the outer surface of the support plate 11. A slider 16 is slidably installed on the inner wall of the chute 15. A cover 17 is fixedly installed on the outer surface of the slider 16. The cover 17 is arranged directly above the placement hole 9. A plurality of through holes 19 are evenly formed through the bottom of the cover 17. A transmission rod 13 is rotatably installed through the top of the cover 17. A blower fan blade 14 is fixedly installed at the bottom end of the transmission rod 13. A lifting mechanism is installed between the slider 16 and the support table 1. The lifting mechanism includes a gantry frame 20 fixedly installed on the upper surface of the support table 1. A support column 21 is fixedly installed on the top wall of the gantry frame 20. A guide cylinder 23 is fixedly installed at the bottom end of the support column 21. The guide cylinder 23 and the feeding tray 2 are coaxially arranged. A closed-loop guide groove 24 is formed on the outer circumference of the guide cylinder 23. A guide post 25 is fixedly installed on the outer surface of the slider 16. The guide post 25 is slidably installed on the inner wall of the closed-loop guide groove 24. A driving assembly is installed between the support column 21 and the transmission rod 13. The driving assembly includes a transmission gear ring 22 fixedly installed on the outer circumference of the support column 21. A transmission pipe 12 is rotatably installed through the top end of the support plate 11. The transmission rod 13 is inserted into the interior of the transmission pipe 12, and the transmission rod 13 and the transmission pipe 12 are installed through spline transmission. A transmission gear 18 is fixedly installed at the top end of the transmission pipe 12. The transmission gear 18 meshes with the transmission gear ring 22. A plurality of ventilation holes 10 are formed through the outer circumference of the feeding tray 2 near each placement hole 9. The plurality of ventilation holes 10 are all communicated with the interior of the placement hole 9.

[0021] After weighing, the feeding tray 2 is driven to rotate by the stepping motor 26, so that the feeding tray 2 can push the weighed seeds to the electric heating block 5 through the placement hole 9, enabling the electric heating block 5 to perform a drying operation on the seeds and remove the moisture inside the seeds; while the feeding tray 2 rotates, the cover 17 will be driven to rotate as a whole by the support plate 11 and the slider 16. When the guide post 25 installed on the slider 16 moves from the covering section groove 241 to the maintaining section groove 242, the cover 17 moves downward as a whole, so that the bottom of the cover 17 covers the top of the placement hole 9. At the same time, the corresponding transmission gear 18 will roll on the transmission gear ring 22, enabling the transmission gear 18 to drive the blower fan blade 14 to rotate through the transmission pipe 12 and the transmission rod 13, so that the blower fan blade 14 can supply air into the placement hole 9, accelerating the air flow speed inside the placement hole 9, enabling the water vapor generated by seed drying to be quickly discharged from the ventilation holes 10, improving the seed drying efficiency; and the air flow blown by the blower fan blade 14 can blow the seeds in the placement hole 9, enabling the seeds to be evenly heated as a whole.

[0022] In this embodiment, the closed-loop guide groove 24 includes a covering section groove 241, a maintaining section groove 242 and a lifting section groove 243. The closed-loop guide groove 24 is formed by connecting the covering section groove 241, the maintaining section groove 242 and the lifting section groove 243 end to end.

[0023] When the guide post 25 is in the holding section groove 242, the bottom of the cover 17 always covers the placement hole 9, preventing the seeds inside the placement hole 9 from being blown out when the feeding fan blade 14 feeds air.

[0024] In this embodiment, a discharge port 7 is formed through the upper surface of the support table 1 between the first weight sensor 3 and the second weight sensor 4, and a discharge hopper 8 is fixedly installed on the lower surface of the support table 1 near the discharge port 7.

[0025] After the feeding tray 2 drives the seeds to move above the second weight sensor 4, the second weight sensor 4 will weigh the cooled seeds and record the final weight of the seeds, so as to calculate the moisture content of the seeds by combining the initial weight and the final weight of the seeds subsequently; as the feeding tray 2 continues to rotate, the seeds in the placement hole 9 will fall into the discharge port 7 and be discharged through the discharge hopper 8, eliminating the need for manual removal of the seeds after the detection is completed, facilitating continuous moisture detection operations on the seeds and improving the detection operation efficiency.

[0026] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: during use, the seeds to be detected for moisture are placed in the placement hole 9 corresponding to the first weight sensor 3, enabling the first weight sensor 3 to weigh the weight of the seeds falling above it and record the initial weight data; After the weighing is completed, the feeding tray 2 is driven to rotate by the stepping motor 26, enabling the feeding tray 2 to push the weighed seeds to the heating block 5 through the placement hole 9, enabling the heating block 5 to perform a drying operation on the seeds and remove the moisture inside the seeds; while the feeding tray 2 rotates, the cover 17 will be driven to rotate as a whole through the support plate 11 and the slider 16. When the guide post 25 installed on the slider 16 moves from the covering section groove 241 to the holding section groove 242, the whole cover 17 moves downward, causing the bottom of the cover 17 to cover the top of the placement hole 9. At the same time, the corresponding transmission gear 18 will roll on the transmission gear ring 22, enabling the transmission gear 18 to drive the feeding fan blade 14 to rotate through the transmission pipe 12 and the transmission rod 13, enabling the feeding fan blade 14 to blow air into the placement hole 9, accelerating the air flow speed inside the placement hole 9, enabling the water vapor generated by the drying of the seeds to quickly discharge from the ventilation hole 10, and improving the drying efficiency of the seeds; and the air flow blown by the feeding fan blade 14 can blow the seeds in the placement hole 9, enabling the seeds to be evenly heated as a whole; After the seeds are dried, the feeding tray 2 drives the seeds to move to the heat dissipation hole 6. At the same time, the feeding fan blade 14 continues to blow air into the placement hole 9, enabling the dried seeds to quickly cool down and dissipate heat, so that the seeds can return to a stable state, avoiding errors caused by hot air or moisture absorption during subsequent weighing of the seeds; After the feeding tray 2 drives the seeds to move above the second weight sensor 4, the second weight sensor 4 will weigh the cooled seeds and record the final weight of the seeds, so as to calculate the moisture content of the seeds by combining the initial weight and the final weight of the seeds subsequently; As the feeding tray 2 continues to rotate, the seeds in the placement holes 9 will fall into the discharge port 7 and be discharged through the discharge hopper 8, eliminating the need for manual removal of the seeds after the detection is completed, facilitating continuous moisture detection operations on the seeds and improving the detection operation efficiency; When the guide post 25 moves to the lifting section groove 243, the guide post 25 will drive the cover 17 to lift to its original position as a whole, so that the cover 17 no longer blocks the placement holes 9, facilitating subsequent reloading of seeds for moisture detection operations.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
