[0017] Beneficial effects of the present invention:

[0018] 1.

At the same time, the multi-layer conveyor belts are conducive to increasing the residence time and movement path of the seeds in the drying equipment, so that the rice seeds can fully receive heat, ensuring that the drying effect of the rice seeds is more uniform, which is conducive to improving the drying efficiency of the rice seeds.

[0019] 2. By turning on the fifth motor on several isolation units, the fifth motor drives several baffles on the rotating rod to rotate, so that the conveyor belt can stir the rice seeds in all directions during the transportation process, which is conducive to breaking the accumulation state of seeds that may form on the conveyor belt, so that each seed has the opportunity to fully contact with the hot air, and cooperate with the multi-layer conveyor belt to transport the seeds. On the one hand, it is beneficial for the seeds to undergo multiple stirring and movement during the transportation process, ensuring that all seeds can receive uniform heat transfer at different heights and positions, maximizing their contact area with hot air, accelerating water evaporation and diffusion, further speeding up the drying speed, shortening the overall drying time, effectively avoiding local over-drying or under-drying, and further improving the uniformity and quality of rice seed drying. On the other hand, stirring can prevent seeds from sticking together, maintain the integrity of seed particles, and avoid the decline of seed quality due to drying.

[0020] 3. By turning on the hot air blower on the preheating and drying component, the hot air is passed into the box through the air supply pipe and the exhaust pipe, and the third motor on the separation unit is turned on. The third motor drives the guide plate to rotate, and the guide plate evenly directs the hot air to different positions of the box, which is not only conducive to quickly raising the temperature in the box to the specified temperature, but also ensures that the rice seeds on each conveyor belt can obtain uniform and sufficient hot air, avoiding the rice seeds from being affected by local excessive temperature during the drying process. The activity of the seeds is further improved, and the safety of the dryer is higher during operation. In addition, the seeds are turned and stirred by several baffles on each conveyor belt and the separation unit, which is convenient for constantly changing the contact angle between the seeds and the hot air, which is conducive to the hot air being able to penetrate the seed layer more efficiently and take away moisture on the surface and inside of the seeds, thereby strengthening heat exchange, reducing energy consumption, and ensuring the consistency and stability of the rice seed drying quality.

By turning on the first motor 105 on the feeding component 1, the first motor 105 drives the spiral conveying rod 106 to rotate, and the rice seeds to be dried are poured into the feeding trough 102, which is conducive to the spiral conveying rod 106 to convey the rice seeds to one end of the discharge pipe 104, ensuring that the rice seeds are stably and efficiently transported to the conveyor belt 404 of each system preheating and drying component 3 through the discharge pipe 104, so that the spiral conveying rod 106 can accurately and sequentially deliver the seeds to the starting position of each layer of the conveyor belt 404, which is conducive to the orderly and continuous loading of rice seeds, avoiding the seed accumulation or blockage problems that may occur in traditional loading methods, and greatly improving the loading efficiency and stability.

[0037] In an optional embodiment of the embodiment of the present invention, a base frame 5 is welded to the bottom of the box 201, and an observation port is provided on one side of the box 201.

A second motor 2031 is installed at one end of the blocking unit 203, and a partition 2032 is movably connected to one end of the second motor 2031 through a rotating shaft. The partition 2032 has a cylindrical structure and is provided on the inner wall of the discharge pipe 202.

[0038] In an optional implementation of the embodiment of the present invention, a hot air blower 301 is installed in the middle of one side of the box body 201, and a partition unit 304 is provided at one end of each of the exhaust pipes 303 away from the air supply pipe 302. A third motor 3041 is installed at one end of the partition unit 304, and a guide plate 3042 is movably connected to one end of the third motor 3041 via a rotating shaft. By turning on the hot air blower 301 on the preheating and drying component 3, the hot air blower 301 passes hot air into the box body 201 through the air supply pipe 302 and the exhaust pipe 303. In conjunction with opening the third motor 3041 on the partition unit 304, the third motor 3041 drives the guide plate 3042 to rotate, and the guide plate 3042 evenly directs the hot air to different positions of the box 201, which not only helps to quickly increase the temperature in the box 201 to the specified temperature, but also ensures that the rice seeds on each conveyor belt 404 can obtain uniform and sufficient hot air, avoiding the occurrence of local excessive temperature affecting the activity of the rice seeds during the drying process, and further improving the safety of the dryer during operation.

[0039] In an optional implementation of an embodiment of the present invention, the exhaust pipe 303 is arranged at an angle, the guide plate 3042 is a cylindrical structure, and the guide plate 3042 is arranged on the inner wall of the exhaust pipe 303, which is conducive to smoothly adjusting the angle of the guide plate 3042, thereby facilitating the hot air to pass stably into the box body 201 through the exhaust pipe 303, thereby preheating the interior of the box body 201.

[0040] In an optional implementation of an embodiment of the present invention, several transport components 4 are staggered, and a support frame 401 is provided on the transport component 4. A fourth motor 402 is installed at the end of one side of the support frame 401, and a conveyor belt 404 is provided in the middle of the support frame 401. Both ends of the conveyor belt 404 are connected to the support frame 401 through a rotating shaft, and the fourth motor 402 is movably connected to the conveyor belt 404 through the rotating shaft. Baffles 403 are provided on both sides of the conveyor belt 404, and the two baffles 403 are welded to the support frame 401. By turning on the fourth motor 402 on several transport components 4, the multi-layer conveyor belt 404 is conducive to increasing the residence time and movement path of the seeds in the drying equipment, so that the rice seeds can fully receive heat, ensuring that the drying effect of the rice seeds is more uniform, and thus helping to improve the drying efficiency of the rice seeds.

[0041] In an optional implementation of the embodiment of the present invention, a number of isolating units 405 are arranged at equal intervals between the two baffles 403, and the isolating units 405 are arranged above the conveyor belt 404.

By turning on the fifth motors 4051 on the several isolating units 405, the fifth motors 4051 drive the several baffles 4053 on the rotating rod 4052 to rotate, so that the conveyor belt 404 can perform all-round stirring of the rice seeds during the transportation process, which is conducive to breaking the seeds on the conveyor belt. The accumulation state that may be formed on 404 gives each seed the opportunity to fully contact with the hot air, and cooperates with the multi-layer conveyor belt 404 to transport the seeds. On the one hand, it is beneficial for the seeds to undergo multiple stirring and movement during the transportation process, ensuring that all seeds can receive uniform heat transfer at different heights and positions, maximizing their contact area with the hot air, accelerating water evaporation and diffusion, further accelerating the drying speed, shortening the overall drying time, and effectively avoiding local over-drying or under-drying, further improving the uniformity and quality of rice seed drying. On the other hand, stirring can prevent seeds from sticking together, maintain the integrity of seed particles, and avoid seed quality degradation due to drying.

[0042] When in use, first, the first motor 105 on the feeding assembly 1 is turned on, and the first motor 105 drives the spiral conveying rod 106 to rotate, and the rice seeds to be dried are poured into the feeding trough 102. The spiral conveying rod 106 conveys the rice seeds to one end of the discharge pipe 104. The rice seeds fall onto the conveyor belt 404 of the top preheating and drying assembly 3 through the discharge pipe 104, ensuring that the rice seeds are stably and efficiently transported to the conveyor belt 404 of each system preheating and drying assembly 3 through the discharge pipe 104. The spiral conveying rod 106 accurately and sequentially delivers the seeds to the starting position of each layer of the conveyor belt 404;

[0043] Then, the fourth motor 402 on the transport component 4 is turned on, and the fourth motor 402 drives the conveyor belt 404 to rotate, which is conducive to the orderly and continuous feeding of rice seeds, and avoids the problem of seed accumulation or blockage that may occur in the traditional feeding method. The fifth motor 4051 on the isolation unit 405 is turned on, and the fifth motor 4051 drives the multiple baffles 4053 on the rotating rod 4052 to rotate, so as to stir the rice seeds on the conveyor belt 404, which is conducive to breaking the accumulation state that may be formed on the conveyor belt 404 of the seeds, so that each seed has the opportunity to fully contact with the hot air. The seeds are transported by the multi-layer conveyor belt 404, which is conducive to the seeds being stirred and moved multiple times during the transportation process, so that the contact area between the seeds and the hot air is maximized, the evaporation and diffusion of water are accelerated, the drying speed is further accelerated, the overall drying time is shortened, and the situation of excessive or insufficient local drying is effectively avoided, thereby further improving the uniformity and quality of the rice seed drying.

[0044] Finally, the hot air blower 301 on the preheating and drying component 3 is turned on, and the hot air blower 301 passes the hot air into the box 201 through the air supply pipe 302 and the exhaust pipe 303, and cooperates with the opening of the third motor 3041 on the partition unit 304, and the third motor 3041 drives the guide plate 3042 to rotate, and the guide plate 3042 evenly guides the hot air to different positions of the box 201, which is not only conducive to quickly raising the temperature in the box 201 to the specified temperature, but also ensures that the rice seeds on each conveyor belt 404 can obtain uniform and sufficient hot air, avoiding the occurrence of the rice seeds being affected by the local high temperature during the drying process. The second motor 2031 is turned on, and the second motor 2031 drives the partition 2032 to rotate, and the dried rice seeds are discharged through the discharge pipe 202.
