However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides an agricultural seed drying device, including a drying box 1, a conveying mechanism 3 is arranged near the lower part of the drying box 1, a positioning mechanism 4 is arranged at the upper middle part of the drying box 1, the conveying mechanism 3 includes two driving rollers 301, two driven rollers 302, two transmission gears 304 and a driving motor 305, the two driving rollers 301 and the two driven rollers 302 are symmetrically connected to rotate between the front and rear inner surface walls of the drying box 1, the driving motor 305 is installed on the front surface of the drying box 1, the two transmission gears 304 are symmetrically connected to the rear surface of the drying box 1, and the outer surfaces of the driving rollers 301 and the adjacent driven rollers 302 are symmetrically connected to the outer surfaces of the driving rollers 301 and the adjacent driven rollers 302. A conveyor belt 303 is sleeved between the surfaces, two driving rollers 301 are arranged in the middle position near the bottom of the drying box 1, and two driven rollers 302 are arranged in the edges of the two sides of the drying box 1, and the two driving rollers 301 are fixedly connected to the two transmission gears 304 through shafts respectively, and the two transmission gears 304 are meshingly connected, and the first hot air blower 2 is symmetrically installed on the outer surfaces of both sides of the drying box 1 near the top, and a top cover 11 is installed on the top of the drying box 1, and two second hot air blowers 21 are symmetrically installed on the top of the top cover 11, and the bottom of the drying box 1 is fixedly connected with support legs 12 near the four corners, and the front surface of the drying box 1 is symmetrically fixedly connected with a feed hopper 13.

[0024] The effect achieved by the entire embodiment 1 is that when the device is used to dry newly harvested seeds, they are first put into the interior of the drying box 1 through the two feeding hoppers 13. The new seeds entering the drying box 1 will fall onto the two conveyor belts 303 and roll down to a lower place. Then, the first hot air blower 2 and the second hot air blower 21 are started to send hot air into the drying box 1 to blow towards the seeds, and the driving motor 305 is started at the same time. At this time, the driving motor 305 will drive one of the driving rollers 301 to rotate, and the driving roller 301 will drive the other driving roller 301 to rotate synchronously in the opposite direction under the action of the two transmission gears 304. At this time, the two driving rollers 301 cooperate with the corresponding driven rollers 302 to drive the conveyor belt 303 to rotate in opposite directions on both sides, thereby The seeds that are accumulated at the bottom and then contact the surface of the conveyor belt 303 are transported upward. During the transportation process, some seeds will be transported to the highest point, and some seeds will roll to the lower point due to gravity. The seeds transported to the highest point will be blown to the lower point under the action of the two first hot air blowers 2. During the operation of this device, the seeds are always in a state of being turned over, and can be quickly dried under the action of the first hot air blower 2 and the second hot air blower 21. The overall drying efficiency is high and the drying effect is good. The lowest point of the first hot air blower 2 corresponds to the highest point of the conveyor belt 303 in height. There is a gap between the two driving rollers 301, and the gap is blocked by the V-frame 404 and the roller shaft 405. The support legs 12 play a role in supporting the device off the ground.

[0025] Embodiment 2, as Figure 1-Figure 5As shown, a discharge port 14 is provided near the middle of the bottom of the drying box 1, and the positioning mechanism 4 includes an H-shaped frame 401, which is fixedly connected between the front and rear inner walls of the drying box 1 near the middle, and an electric push rod 402 is fixedly connected to the inner top of the H-shaped frame 401, and a T-shaped frame 403 is fixedly connected to the bottom of the electric push rod 402, and a V-shaped frame 404 is fixedly connected to the bottom of the T-shaped frame 403, and rollers 405 are rotatably connected to the bottom of the V-shaped frame 404 near both sides, and the outer surface of the roller 405 is in contact with the outer surface of the conveyor belt 303.

[0026] The effect achieved by the entire embodiment 2 is that when the conveyor belt 303 is running, the roller 405 at the bottom of the V-frame 404 is in contact with the surface of the conveyor belt 303 and rotates, which mainly plays the role of covering the gap between the two conveyor belts 303 to prevent seeds from falling. When the seeds are dried, the electric push rod 402 at the top of the H-frame 401 is started to drive the T-frame 403 to move upward. At this time, the V-frame 404 will drive the two rollers 405 away from the surface of the conveyor belt 303 to leak out the gap between the two conveyor belts 303, and then control the drive motor 305 to rotate in the opposite direction so that the two conveyor belts 303 transport the seeds toward the middle gap. Then the seeds will be discharged through the gap and the discharge port 14. The overall degree of automation is high, which improves the overall seed drying efficiency.

[0027] Working principle: When using this device to dry newly harvested seeds, first put them into the interior of the drying box 1 through the two feeding hoppers 13. The new seeds entering the drying box 1 will fall onto the two conveyor belts 303 and roll down to a lower place. Then start the first hot air blower 2 and the second hot air blower 21 to send hot air into the drying box 1 to blow towards the seeds, and start the driving motor 305 at the same time. At this time, the driving motor 305 will drive one of the driving rollers 301 to rotate, and the driving roller 301 will drive the other driving roller 301 to rotate synchronously in the opposite direction under the action of the two transmission gears 304. At this time, the two driving rollers 301 cooperate with the corresponding driven rollers 302 to drive the conveyor belt 303 to rotate in opposite directions on both sides, so that the seeds accumulated at the bottom and then in contact with the surface of the conveyor belt 303 are transported upward. During the transportation process, some seeds will be transported to the highest place. Some seeds will roll down to a lower place due to the action of gravity, while the seeds transported to the highest place will be blown down to a lower place under the action of the two first hot air blowers 2. During the operation of the device, the seeds are always in a state of being turned over, and can be quickly dried under the action of the first hot air blower 2 and the second hot air blower 21. The overall drying efficiency is high and the drying effect is good. When the seed drying is completed, the electric push rod 402 at the top of the H-shaped frame 401 is started to drive the T-shaped frame 403 to move upward. At this time, the V-shaped frame 404 will drive the two rollers 405 away from the surface of the conveyor belt 303 to leak out the gap between the two conveyor belts 303, and then control the drive motor 305 to rotate in the opposite direction so that the two conveyor belts 303 transport the seeds to the middle gap direction, and then the seeds will be discharged through the gap and the discharge port 14. The overall degree of automation is high, which improves the overall seed drying efficiency.
