[0002] Grain seed drying devices are essential equipment in modern agricultural production, used to reduce the moisture content of harvested grains or seeds to a safe storage level to prevent mildew, pests, and germination, ensuring the long-term preservation and commercial value of seeds. Such devices accelerate moisture evaporation and improve drying efficiency through different heating and ventilation technologies.

[0003] During the use of current grain seed drying devices, staff often find that most current grain seed drying devices directly put the seeds to be dried into the drying box, where the seeds are prone to accumulate in the box, and the seeds in the middle are difficult to come into full contact with the hot air, resulting in a reduction in drying efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Example 1, as shown in Figure 1 and Figure 2As shown in the figure, a grain seed drying device includes a box body 1, a feeding hopper 2 is fixedly communicated with the box body 1, a blower 3 is fixedly connected to the box body 1, an air outlet pipe 4 is fixedly connected to the output end of the blower 3, a blowing pipe 5 is communicated with the air outlet pipe 4, a plurality of air outlet nozzles 6 are arranged on the blowing pipe 5, and an electric heating pipe 7 is fixedly connected in the box body 1.

[0028] Referring to Figures 1 to 4 , a grading structure 8 is arranged in the box body 1. The grading structure 8 is mainly composed of two grading plates 81. Both grading plates 81 are arranged in the box body 1. Two discharge ports 811 are opened on one side of the box body 1. Two sliding grooves 82 are opened on one side of the box body 1. A slider 83 is slidably connected in the sliding grooves 82. The slider 83 is fixedly connected to the grading plate 81. The seeds to be dried are put into the box body 1 through the feeding hopper 2. The blower 3 is started. The blower 3 inputs external air into the interior of the box body 1 through the air outlet pipe 4 and the blowing pipe 5 and blows it to the seeds above through a plurality of air outlet nozzles 6. The air is heated when passing through the electric heating pipe 7. The aperture of the upper grading plate 81 is larger than that of the lower grading plate 81. When the seeds fall on the upper grading plate 81, some of them will fall onto the lower grading plate 81. Then, by sliding the two grading plates 81 up and down, the seeds can be driven to vibrate and spread out, so as to increase the contact area between the seeds and the hot air and improve the drying effect. The dried seeds are discharged through the two discharge ports 811, thus avoiding the situation that in most current grain seed drying devices, the seeds to be dried are directly put into the drying box, the seeds are easy to accumulate in the box body 1, and the seeds in the middle are difficult to fully contact with the hot air, resulting in a reduction in drying efficiency. Two connecting rods 84 are fixedly connected to both grading plates 81. A connecting block 85 is fixedly connected to the two connecting rods 84 together. By moving the connecting block 85 up and down, the two connecting rods 84 can be driven to move up and down, and then the two grading plates 81 can be driven to vibrate up and down. A round rod 86 is rotatably connected to the box body 1. One end of the round rod 86 is fixedly connected to a disc 87. A sliding rod 88 is fixedly connected to the disc 87. The sliding rod 88 is slidably connected to the connecting block 85. By rotating the round rod 86 to drive the disc 87 to rotate, the sliding rod 88 can be made to move in a circular motion, and then the connecting block 85 can be driven to move up and down. A first motor 89 is fixedly connected to the box body 1. The output shaft of the first motor 89 is fixedly connected to the round rod 86. By starting the first motor 89, the output shaft of the first motor 89 drives the round rod 86 to rotate, making the operation more convenient. A spring 810 is fixedly connected to the slider 83. One end of the spring 810 is fixedly connected to the inner wall of the sliding groove 82. When the grading plate 81 drives the slider 83 to slide, the spring 810 will be driven to deform and then reset, which can improve the vibration effect.

[0029] Referring to Figure 2 and Figure 4, a circulation structure 9 is provided on the box body 1. The circulation structure 9 mainly consists of two discharge hoppers 91. Both discharge hoppers 91 are fixedly connected to one side of the box body 1. The two discharge hoppers 91 communicate with the two discharge ports 811. A cylinder 92 is fixedly connected in common on the two discharge hoppers 91. The seeds falling out through the two discharge ports 811 will enter the cylinder 92 through the discharge hoppers 91. A screw conveyor 93 is rotatably connected in the cylinder 92. A second motor 94 is fixedly connected to the cylinder 92. The output shaft of the second motor 94 is fixedly connected to the screw conveyor 93. Starting the second motor 94, the output shaft of the second motor 94 drives the screw conveyor 93 to rotate, and the dried seeds can be transported upward. A recovery pipe 95 is fixedly connected to the cylinder 92. A first valve 97 is provided on the recovery pipe 95. A blanking pipe 96 is fixedly connected to the cylinder 92. A second valve 98 is provided on the blanking pipe 96. Opening the first valve 97 and closing the second valve 98 can make the seeds fall back into the box body 1 through the recovery pipe 95, and then be dried for the second time to further improve the drying effect. After multiple drying operations, opening the second valve 98 and closing the first valve 97 can make the seeds be discharged through the blanking pipe 96.

[0030] Working principle: The seeds to be dried are put into the box body 1 through the feeding hopper 2. The fan 3 is started. The fan 3 inputs the external air into the interior of the box body 1 through the air outlet pipe 4 and the air blowing pipe 5, and blows it upward to the seeds through a number of air outlet nozzles 6. The air is heated when passing through the electric heating pipe 7. The aperture of the upper grading plate 81 is larger than that of the lower grading plate 81. When the seeds fall on the upper grading plate 81, some of them will fall onto the lower grading plate 81. Then, by sliding the two grading plates 81 up and down, the seeds can be driven to vibrate, making them spread out flat, so as to increase the contact area between the seeds and the hot air and improve the drying effect. The dried seeds are discharged through the two discharge ports 811, thus avoiding the situation that most of the current grain seed drying devices directly put the seeds to be dried into the drying box, where the seeds are prone to accumulate in the box body 1, and the seeds in the middle are difficult to come into full contact with the hot air, resulting in a reduction in drying efficiency. The two connecting rods 84 can be driven to move up and down by moving the connecting block 85 up and down, and then the two grading plates 81 are driven to vibrate up and down. When the round rod 86 rotates, the disc 87 is driven to rotate, which can make the sliding rod 88 move in a circular motion, and then drive the connecting block 85 to move up and down. By starting the first motor 89, the output shaft of the first motor 89 drives the round rod 86 to rotate, making the operation more convenient. When the grading plate 81 drives the slider 83 to slide, the spring 810 will be deformed and then reset, which can improve the vibration effect. The seeds falling out through the two discharge ports 811 will enter the cylinder 92 through the discharge hopper 91. By starting the second motor 94, the output shaft of the second motor 94 drives the auger 93 to rotate, and the dried seeds can be transported upward. Opening the first valve 97 and closing the second valve 98 can make the seeds fall back into the box body 1 through the recovery pipe 95 for secondary drying to further improve the drying effect. After multiple drying operations, opening the second valve 98 and closing the first valve 97 can make the seeds be discharged through the blanking pipe 96.
