[0002] With the development of agricultural modernization, grain harvesting and storage have become crucial aspects of agricultural production. To ensure grain quality and extend its shelf life, air drying, as one of the most direct and effective processing methods, occupies an irreplaceable position in grain processing. Traditional grain air drying methods mostly employ natural sun-drying or simple mechanical air drying. While these methods can meet basic drying requirements, they are significantly insufficient in terms of efficiency and uniformity, especially during rainy seasons or in areas with high humidity, making it difficult to achieve a rapid and efficient drying process.

[0003] While existing technologies utilize fans to blow air onto grain on a conveyor belt to accelerate the drying process, the grain often clumps together, making it difficult for the grain to come into contact with air, thus affecting the overall drying effect. Furthermore, the lack of an effective turning mechanism means that some grain may experience uneven heating due to prolonged contact with the conveyor belt, leading to a decline in quality. Therefore, improving drying efficiency and uniformity while ensuring grain safety has become a pressing issue. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a grain drying device, including a conveyor belt body 1, a support frame 2 on the top of the conveyor belt body 1, a drying mechanism 3 consisting of a fan and a blower pipe on the top of the support frame 2, a multi-directional drive mechanism 4 on one inner wall of the support frame 2, a turning mechanism 6 above the conveyor belt body 1, the turning mechanism 6 and the multi-directional drive mechanism 4 being connected by a connecting positioning component 5, the turning mechanism 6 consisting of a fixed frame 61, a turning plate 62 and a motor 63, the turning plate 62 being an arc-shaped structure and installed inside the fixed frame 61, and the motor 63... The model is Y132S-4, and it is fixedly installed on one side of the outer wall of the fixed frame 61. When the grain is conveyed on the conveyor belt body 1 to the support frame 2 area, the drying mechanism 3, composed of a fan and a blower, starts to work. The air force is evenly distributed to the entire conveyor belt area through the blower, accelerating the grain drying process. At the same time, the multi-directional drive mechanism 4 starts and drives the turning mechanism 6 to move through the connecting positioning component 5. The motor 63 in the turning mechanism 6 drives the turning plate 62 to rotate. During the rotation, the turning plate 62 can effectively turn the grain on the conveyor belt, ensuring that each grain is fully dried. Exposed to wind, the uniformity and efficiency of air drying are greatly improved. Simultaneously, motor 63, through precise control of the rotation speed and angle of the turning plate 62, further optimizes the turning effect, preventing uneven heating of the grain due to prolonged contact with the conveyor belt and effectively protecting grain quality. In summary, this device, through the coordinated working mode of the air drying mechanism 3, the multi-directional drive mechanism 4, and the turning mechanism 6, successfully solves key problems in traditional air drying methods such as grain accumulation, uneven drying, and quality degradation, significantly improving drying quality and production efficiency. The multi-directional drive mechanism 4 includes a linear guide rail 41, a guide... The system comprises block 42, movable plate 43, and push cylinder 44. A linear guide rail 41 is mounted on the inner side wall of the support frame 2. The guide block 42 is mounted on the linear guide rail 41. The movable plate 43 is movably connected to the outer side of the guide block 42. The inner side of the top of the movable plate 43 is movably connected to the outer wall of the guide block 42 via a pivot pin. The push cylinder 44 is model SC100-100. The push cylinder 44 is connected between the guide block 42 and the corresponding side of the movable plate 43, and the output end of the push cylinder 44 is movably connected to the inner side of the bottom end of the movable plate 43 via a hinge. In this structure, the linear guide rail 41 drives the guide block 42 to move vertically. The movable plate 43 moves up and down, and the cylinder 44 drives the tilt angle of the movable plate 43, thereby adjusting the tilting amplitude and direction of the tilting plate 62 of the tilting mechanism 6. This not only ensures that the tilting plate 62 can evenly tilt the grain on the conveyor belt, but also further improves the uniformity and efficiency of air drying by precisely controlling the tilting frequency and range. At the same time, the combination of the linear guide rail 41 and the guide block 42 provides stable guiding support, ensuring the smoothness and reliability of the tilting process. The connecting positioning assembly 5 includes a positioning shaft 51 and a positioning sleeve 52. The positioning shaft 51 is laterally fixed to the outside of the movable plate 43.The connection between the positioning shaft 51 and the movable plate 43 is fixed by screws. The positioning sleeve 52 is fixed to one side of the top of the fixed frame 61 and sleeved on the outside of the positioning shaft 51. The positioning sleeve 52 is connected to the fixing bolt by a threaded structure. This connection positioning assembly 5, through the cooperation of the positioning shaft 51 and the positioning sleeve 52, pre-positions the turning mechanism 6 in a suitable position, ensuring that the turning plate 62 is in the optimal working position in the initial state, thus providing a stable starting point for subsequent turning and air-drying operations. Several protrusions 621 are evenly provided on the inner wall of the turning plate 62. The protrusions 621 and the turning plate 62 are integral structures, and the gaps between the protrusions 621 are all provided with material passages 622. The protrusions 621 of this structure can increase the friction between the turning plate 62 and the grain, ensuring that the grain can be turned more evenly during the turning process. The material passages 622 can allow some smaller grain particles or debris to pass through, further improving the efficiency of turning. To improve the efficiency and uniformity of air drying, a sponge pad 623 is glued and fixed to the bottom of the turning plate 62, and both ends of the turning plate 62 are connected to the inner walls of the two sides of the fixed frame 61 through a pivot. This structure of the sponge pad 623 can reduce the impact and wear on the grain during the turning process, protecting the integrity of the grain. The top of the fixed frame 61 has a ring-shaped air passage 611 inside, with an air inlet at one end and several air outlets 612 evenly distributed at the bottom. This structure allows the air passage 611 to be connected to the blower pipe of the air drying mechanism 3 through the air inlet via an air guide pipe, guiding part of the air force generated by the air drying mechanism 3 into the air passage 611. The air force is evenly distributed through the air passage 611 and blown out evenly from the air outlets 612 at the bottom, covering the grain on the turning plate 62, further ensuring that each grain of grain is fully exposed to the air force, improving the uniformity and efficiency of air drying.

[0018] Working principle: When using this grain drying device, firstly, connect an air inlet pipe between the spray pipe of the drying mechanism 3 and the air inlet of the air passage 611 at the top of the fixed frame 61 to ensure that the air force can be smoothly introduced into the air passage 611. Then, the grain is placed on the conveyor belt body 1 for conveying. The grain gradually enters the area of ​​the support frame 2. At this time, the drying mechanism 3 starts to work at the top of the support frame 2. The air force is evenly distributed to the entire conveyor belt area through the spray pipe, accelerating the drying process of the grain. At the same time, the multi-directional drive mechanism 4 is activated. The linear guide rail 41 drives the guide block 42 to move vertically, and the movable plate 43 begins to move up and down. When the cylinder 44 is driven, it changes the tilt angle of the movable plate 43. This allows adjustment of the turning amplitude and direction of the turning plate 62 of the turning mechanism 6. Simultaneously, the motor 63 drives the turning plate 62 to rotate. During rotation, the turning plate 62 increases the friction with the grain using the protrusions 621 on its inner wall, ensuring that the grain can be turned evenly. During the turning process, the air force in the air chamber 611 is blown out evenly through the air outlet 612 at the bottom, covering the grain on the turning plate 62, further ensuring that each grain can fully contact the air force, further improving the uniformity and efficiency of air drying. Throughout the process, the positioning shaft 51 and positioning sleeve 52 connecting the positioning component 5 ensure that the turning mechanism 6 is in the optimal working position in the initial state, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
