[0002] Currently, the planting area of corn in my country is about 300 million mu, and it is widely planted in tropical and temperate regions around the world. In order to facilitate the long-term storage of corn, it is necessary to thresh the corn and then dry the threshed corn.
[0003] Existing corn drying equipment is mostly quite simple, typically involving feeding a batch of corn into the drying equipment for uniform drying. However, corn kernels vary in size, with larger kernels having a larger surface area and volume, containing more moisture both internally and on the surface, while smaller kernels contain less moisture. Existing drying equipment cannot differentiate between these sizes. More importantly, in current corn processing technologies, corn kernels inevitably need to be screened after drying, which significantly increases processing time and reduces production efficiency. Therefore, it is necessary to develop a circulating corn dryer to address the shortcomings of existing technologies. Utility Model Content

[0025] 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.
[0026] like Figures 1 to 6As shown, this utility model provides a circulating corn dryer, including a drying cylinder 1. Several transmission components 2 are evenly distributed from top to bottom inside the drying cylinder 1. A drive component 3 is movably sleeved inside the several transmission components 2. The lower end of the drive component 3 passes through the drying cylinder 1 and is connected to a rotating mechanism. The upper end of the drive component 3 extends to the top of the drying cylinder 1. A feeding hopper 4 is provided at the top of the drying cylinder 1, located outside the drive component 3. The outer diameter of the drive component 3 is smaller than the inner diameter of the feeding hopper 4.
[0027] The transmission assembly 2 includes a first linkage ring 21 coaxially sleeved between the drying cylinder 1 and the drive assembly 3. The first linkage ring 21 is movably connected to a plurality of uniformly distributed filter drying plates 22. The sides of two adjacent filter drying plates 22 are tightly fitted together. A hinge block 23 connects the filter drying plates 22 and the first linkage ring 21. The bottom of the plurality of filter drying plates 22 is provided with a linkage assembly 24 sleeved on the outer surface of the drive assembly 3. Due to the arrangement of the plurality of transmission assemblies 2, with the cooperation of the feeding hopper 4, the corn poured in can be filtered and screened to achieve the effect of automated drying and screening, and at the same time, it is convenient to collect the corn after screening one by one.
[0028] The filter holes of the filter drying plates 22 gradually decrease in size from top to bottom. The outer surface of the filter drying plates 22 and the inner wall of the filter holes are smooth. Because the corn kernels are distributed from top to bottom according to their size, the kernels with different surface moisture contents can be distributed in sequence to adapt to the flow direction of the hot airflow, thereby helping to improve the drying efficiency.
[0029] The linkage component 24 includes a second linkage ring 241 attached to the bottom of several filter drying plates 22. The second linkage ring 241 is longitudinally slidably engaged with the outer surface of the drive component 3. The interior of the second linkage ring 241 has several evenly distributed material passage chambers 242 and limiting grooves 243, which correspond one-to-one and are alternately distributed. Due to the setting of the material passage chambers 242, it is ensured that the corn poured in can pass through the material passage chambers 242 and penetrate the linkage component 24 so that it can finally fall onto the corresponding filter drying plate 22. With the cooperation of the limiting grooves 243 and the linkage rods 244, it is ensured that when the drive component 3 rotates, it can drive the first linkage ring 21 and several filter drying plates 22 to rotate synchronously through the second linkage ring 241, so that the filtered corn can be spread on the filter drying plate 22 and fully contact the hot airflow along with the filter drying plate 22, thereby improving the drying efficiency.
[0030] The upper and lower ends of the material passage chamber 242 pass through the second linkage ring 241 and are connected to the interior of the drying cylinder 1. The internal sliding groove 243 is slidably engaged with the linkage rod 244. The top of the linkage rod 244 passes through the limiting groove 243 and extends to the top of the second linkage ring 241 and is fixedly connected to the bottom of the filter drying plate 22.
[0031] The drive assembly 3 includes a rotating shaft 31 rotatably connected inside the drying cylinder 1. The outer surface of the rotating shaft 31 and the inner wall of the second linkage ring 241 are both rough. The second linkage ring 241 is tightly fitted onto the outer surface of the rotating shaft 31. Since the second linkage ring 241 is longitudinally slidably engaged with the outside of the rotating shaft 31, it ensures that the linkage assembly 24 can rotate with the drive assembly 3. At the same time, when the adapter lifting ring 32 moves up and down, it can push the filter drying plate 22 to swing upward through the linkage assembly 24. Moreover, after the adapter lifting ring 32 moves away from the linkage assembly 24, it will not detach from the filter drying plate 22 under the action of gravity, thereby ensuring that the linkage slide rod 244 is always slidably engaged inside the limiting slide groove 243.
[0032] The rotating shaft 31 has several evenly distributed fitting grooves 33 on its side and several evenly distributed connecting grooves 34 inside. The connecting grooves 34 correspond one-to-one with the rotating shaft 31 and are interconnected.
[0033] The adapter slide rod 35 is slidably engaged inside the adapter slide groove 33, and the connecting slide rod 36 is slidably engaged inside the connecting slide groove 34. The opposing surfaces of the adapter slide rod 35 and the connecting slide rod 36 are fixedly connected. The height dimensions of the inner cavity of the adapter slide groove 33, the adapter slide rod 35, the inner cavity of the connecting slide groove 34, and the connecting slide rod 36 decrease sequentially. Due to the arrangement of the adapter slide groove 33 and the connecting slide groove 34, the adapter slide rod 35 and the connecting slide rod 36 can slide smoothly up and down with the transmission sleeve 37 within the rotating shaft 31. They can also restrict the movement of the transmission sleeve 37, allowing it to move up and down with the rotating transmission rod 38. Thus, the adapter slide rod 35 and the connecting slide rod 36 drive several external adapter lifting rings 32 to move up and down.
[0034] The rotating shaft 31 is fitted with several matching lifting rings 32. The outer surface of the matching slide rod 35 passes through the matching slide groove 33 and extends to the outside of the rotating shaft 31 and is fixedly connected to the inner wall of the several matching lifting rings 32. The distance between the several matching lifting rings 32 increases from top to bottom. The several matching lifting rings 32 correspond one-to-one with the linkage component 24. The matching lifting rings 32 move up and down with the matching slide rod 35 and eventually contact the second linkage ring 241 at the top of it. Since the distance between the several matching lifting rings 32 increases from top to bottom, when the matching lifting rings 32 move upward, the corresponding linkage component 24 can be driven to move upward from top to bottom through the corresponding matching lifting rings 32, thereby pushing the filter drying plate 22 to swing upward from top to bottom.
[0035] The rotating shaft 31 is movably fitted with a transmission sleeve 37. The inner wall of the connecting slide rod 36 passes through the connecting groove 34 and is fixedly connected to the outer surface of the transmission sleeve 37. The transmission sleeve 37 is threadedly fitted with a transmission rod 38. The transmission rod 38 is rotatably fitted inside the rotating shaft 31. The top of the transmission rod 38 is fixedly connected to a transmission shaft 39, which is rotatably fitted inside the rotating shaft 31. The top of the transmission shaft 39 is fixedly mounted with a drive motor 30. The bottom of the output shaft of the drive motor 30 is fixedly connected to the top of the transmission shaft 39.
[0036] Working principle and usage process of this utility model:
[0037] After assembling the equipment as shown in the figure, the rotating mechanism is activated to drive the rotating shaft 31 to rotate slowly. Then, a batch of corn to be dried is poured into the top of the transmission component 2 inside the drying cylinder 1 through the feeding hopper 4. Under the action of gravity and the continuous rotation of the transmission component 2, corn of different particle sizes is filtered through the filter drying plate 22, causing corn of different particle sizes to fall onto the corresponding filter drying plate 22. The drying system is then activated, allowing the high-temperature hot airflow inside the drying cylinder 1 to remove the moisture from the surface of the corn. After drying is complete, the drying system is activated, and the rotating mechanism stops operating. At this time, the drive motor 30 runs, which drives the transmission rod 38 to rotate through the transmission shaft 39. This, in turn, causes the rotating shaft 31, the matching slide 33, the matching slide rod 35, and the connecting slide 3 to rotate. Under the constraint of the connecting slide rod 36, the transmission rod 38 drives the transmission sleeve 37 to move upward, and then through the connecting slide rod 36 and the adapter slide rod 35, it drives the outer several adapter lifting rings 32 to move upward slowly. Since the distance between each adapter lifting ring 32 and the bottom of the corresponding transmission component 2 is different, when the several adapter lifting rings 32 move upward, they can push their respective corresponding linkage components 24 one by one from top to bottom. Then, under the constraint of the hinge block 23, the upward movement of the second linkage ring 241 can, with the cooperation of the limiting slide groove 243 and the linkage slide rod 244, make the end of the filter drying plate 22 close to the drive component 3 slowly swing upward and reach an inclined state, so that the dried corn supported on its top slides down, thereby completing the drying and screening.
