[0002] In order to extend the shelf life of rice seeds, it is necessary to reduce the moisture content of crop seeds. The existing practice is usually to reduce the moisture content of crop seeds by airing or drying.

[0003] Sun drying is not suitable for large-scale seed processing. Therefore, the existing technology often uses drying devices. There are many types of existing drying devices, but their working principles are basically the same. They all pass hot air through the outside of the seeds to heat the seeds, thereby evaporating their moisture. During the drying process, most existing devices use mesh conveyor belts for horizontal transportation. The position of the seeds remains consistent during transportation, resulting in a certain difference in the degree of drying on both sides of the seeds. Therefore, it is necessary to increase the temperature or reduce the transportation rate, thereby extending the drying time to a certain extent. Therefore, to solve the above problems, the present application provides a rice seed drying device.

The two conveyor belts are clearance-matched to clamp and fix the two sides of the seed tray.

[0007] Gear discs are fixedly connected to the midpoints of both sides of the seed disc;

[0008] A plurality of racks cooperating with the gear discs are evenly distributed on the inner sides of the two conveyor belts.

[0012] Preferably, a spring piece is welded to the top of the end block, and the spring piece protrudes from the end block.

[0013] Preferably, the seed plate includes a supporting plate and a clamping net rotatably connected to the supporting plate, one side of the supporting plate and the clamping net are rotatably connected, and the other side is clamped, and the two are clearance-matched in the horizontal direction, and the gear plate is welded to the midpoint of the outer wall of the supporting plate.

[0024] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0025] Example 1: Reference Figure 1-Figure 5 The rice seed drying device comprises a drying channel 1 and a seed tray 7 for transporting seeds. A heat pump 3 for transporting hot air to the interior of the drying channel 1 is provided at the bottom of the drying channel 1. Conveyor belt 1 and conveyor belt 2 6 are rotatably connected on both sides of the drying channel 1. Conveyor belt 2 6 is located above conveyor belt 1 5 and the two sides are gap-matched to clamp and fix the two sides of the seed tray 7. The inner sides of conveyor belt 1 5 and conveyor belt 2 6 are provided with support plates welded to the inner wall of the drying channel 1. The support plates are used to limit the top of conveyor belt 1 5 and the bottom of conveyor belt 2 6, so as to ensure the stability of conveyor belt 1 5 and conveyor belt 2 6 in the process of transporting the seed tray 7. Both ends of conveyor belt 1 5 are extended to the outside of the drying channel 1. Conveyor belt 2 6 is located at the inner side of the drying channel 1. Conveyor belt 1 5 extends to the outside of the drying channel 1 to carry the seed tray 7, which is convenient for placing the seed tray 7. Conveyor belt 2 6 is located at the inner side of the drying channel 1, so that the seed tray 7 can be clamped and fixed on both sides after entering the inner side of the drying channel 1. The midpoints of both sides are fixedly connected with gear plates 9, and the gear plates 9 are rotatably connected with the end blocks 10 on the side away from the seed disc 7, and the end blocks 10 are rectangular structures. The seed disc 7 is stably placed on the conveyor belt 1 5 through the end blocks 10. The rectangular structure prevents it from rotating. A spring piece 11 is welded on the top of the end block 10, and the spring piece 11 protrudes from the end block 10. The spring piece 11 has upward elasticity. The end block 10 is matched with the spring piece 11, and the gap between the two is larger than the gap between the conveyor belt 1 5 and the conveyor belt 2 6 , thereby achieving a good clamping effect of the conveyor belt 1 5 and the conveyor belt 2 6 on the end block 10 and the spring piece 11, the seed tray 7 includes a carrier tray 701 and a clamping net 702 rotatably connected to the carrier tray 701, the carrier tray 701 and the clamping net 702 are rotatably connected on one side and clamped on the other side, and the horizontal gap between the two is matched, and the gap between the two allows the seeds to be spread flat on the inner side thereof, thereby reducing the accumulation of seeds with each other, thereby ensuring the drying effect, and the gear plate 9 is welded to the midpoint of the outer wall of the carrier tray 701;

[0026] Several racks 8 that cooperate with the gear plate 9 are evenly distributed on the inner side of the two conveyor belts 5. The length of each rack 8 is equal to 1 / 2 of the gear plate 9. The length of the rack 8 allows the transmission gear plate 9 to rotate 1 / 2 when the seed plate 7 passes through the changed position, thereby realizing the flipping of the seed plate 7, thereby improving the drying effect of the seeds.

[0027] The bottom of the drying channel 1 is fixedly connected to a guide cover 4, the output end of the heat pump 3 is connected to the guide cover 4, an air duct 101 connected to the inside of the guide cover 4 is opened at the bottom of the drying channel 1, and the top of the drying channel 1 is fixedly connected to an air guide cover 2 connected thereto, and the air guide cover 2 is used to transport the cooled air flow and water vapor to the outside.

[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
