Description
Technical Field
[0001] The utility model belongs to the technical field of dryers, and particularly relates to a drum-type grain dryer. Background Technique
[0002] Grains are the general term for foods such as cereals and miscellaneous grains. Due to China's large population base, the issue of food security has gradually been taken seriously. The existing foods can not only meet the daily living needs of people, but also have some surpluses for backup. In our family life, we will also collect and store the extra foods. However, when the storage environment of these foods has more moisture, these foods are very likely to become inedible due to spoilage and mildew, resulting in food waste. Therefore, a dryer is needed to dry the grains.
[0003] The existing dryers have the following problems during use:
[0004] 1. During the process of drying grains by the existing dryers, since the grains are damp, they usually stick together in groups. When drying the grains, with the rotation of the drum, the grains cannot be well dispersed, thus affecting the drying effect of the grains.
[0005] 2. During the process of drying grains by the existing dryers, the grains are usually directly added into the inner part of the feed hopper, and the grains are sent to the inner side of the drying cylinder through the feed hopper. The grouped grains are likely to block the feed hopper. For this reason, we propose a drum-type grain dryer. Content of the Utility Model

[0026] To better understand the purpose, structure, and function of the present invention, the following further describes a drum-type grain dryer of the present invention in detail with reference to the drawings.
[0027] As Figures 1-3 shown, a drum-type grain dryer of the present utility model includes a mounting base plate 1. A first fixed support block 2 is fixedly connected to the bottom end of the mounting base plate 1. Moving support mechanisms 3 are symmetrically arranged on the top of the mounting base plate 1. A first moving drying hood 4 is arranged on the top of one of the moving support mechanisms 3, and a second moving drying hood 5 is arranged on the top of the other moving support mechanism 3. First guiding and limiting rings 7 are arranged on the outer sides of the surfaces of the first moving drying hood 4 and the second moving drying hood 5. Second guiding and limiting rings 8 are arranged on the outer sides of the surfaces of the first moving drying hood 4 and the second moving drying hood 5. A feeding and crushing mechanism 9 is fixedly connected to one side of the moving support mechanism 3 close to the first moving drying hood 4. An air extraction and stirring mechanism 10 is fixedly connected to one end of the second moving drying hood 5 far from the first moving drying hood 4. A heating ring 11 is arranged on the outer side of the end surface of the feeding and crushing mechanism 9.
[0028] The moving support mechanism 3 includes a moving mounting plate 12. A universal wheel 13 is fixedly connected to the bottom end of the moving mounting plate 12. Support mounting arms 14 are symmetrically arranged at one end of the top of the moving mounting plate 12. First movable rollers 15 are arranged on the inner sides of the tops of the support mounting arms 14. Fixed support columns 16 are symmetrically arranged at the other end of the top of the moving mounting plate 12. A connecting mounting bottom block 17 is fixedly connected to the top ends of the fixed support columns 16 and the moving mounting plate 12. Fixed mounting arms 18 are symmetrically arranged at one end of the top of the connecting mounting bottom block 17. Second movable rollers 19 are movably connected to the inner sides of the fixed mounting arms 18. A fixed tooth 20 is fixedly connected to one side of the first guiding and limiting ring 7. A first motor 21 is fixedly connected to the top of the connecting mounting bottom block 17. A driving gear 22 is fixedly connected to the output end of the first motor 21. A connecting moving block 35 is fixedly connected to one end of the bottom of the moving mounting plate 12. A threaded rod 36 is connected to the inside of the connecting moving block 35 by threads. One end of the threaded rod 36 is fixedly connected to a fourth motor 37, and the fourth motor 37 is fixedly connected to the mounting base plate 1.
[0029] The driving gear 22 is meshed with the fixed tooth 20. The outer side of the surface of the second movable roller 19 is in mutual fit with the inner side of the first guiding and limiting ring 7. The outer side of the surface of the first movable roller 15 is in mutual fit with the inner side of the second guiding and limiting ring 8, which is convenient for the first motor 21 to drive the fixed tooth 20 to drive the driving gear 22, and then drive the fixed tooth 20, so as to drive the first moving drying hood 4 and the second moving drying hood 5, and roll and turn the grains inside, with convenient operation.
[0030] The feeding and crushing mechanism 9 includes a second fixed support block 23. A connecting and mounting sleeve block 24 is fixedly connected to the top of the second fixed support block 23. A feeding cylinder 25 is fixedly connected inside the connecting and mounting sleeve block 24. One end of the feeding cylinder 25 is fixedly connected to a second motor 26. The output end of the second motor 26 is fixedly connected to a spiral feeding roller 27. A feeding hopper 28 is fixedly connected to one end of the top of the feeding cylinder 25. The other end of the heating ring 11 is fixedly connected to the feeding cylinder 25. This facilitates the second motor 26 to drive the spiral feeding roller 27, enabling the agglomerated grains to be broken when being conveyed between the feeding hopper 28 and the feeding cylinder 25 as the spiral feeding roller 27 rotates, reducing the volume of the agglomerated grains, and then being stably conveyed into the first moving drying hood 4 and the second moving drying hood 5. During subsequent drying, under the action of the air extraction and stirring mechanism 10, the agglomerated grains can be further dispersed, and the operation is convenient.
[0031] The air extraction and stirring mechanism 10 includes a fixed mounting plate 29. A third motor 30 is fixedly connected to the side of the fixed mounting plate 29 away from the second moving drying hood 5. The output end of the third motor 30 is fixedly connected to a rotating mounting rod 31. Stirring arms 32 are fixedly connected to the outer surface of the rotating mounting rod 31. A fixed connecting plate 33 is fixedly connected to the surface of the fixed mounting plate 29. A suction fan 34 is fixedly connected to the surface of the fixed connecting plate 33. This facilitates the third motor 30 to drive the rotating mounting rod 31, enabling the rotating mounting rod 31 to drive the stirring arms 32, so that the stirring arms 32 can strike the agglomerated grains to disperse the grains, enabling the grains to be stably dried, and the water vapor generated during the drying process can be discharged to the outside under the action of the suction fan 34, and the operation is convenient.
[0032] A discharge guide platform 6 is fixedly connected to the middle of the top end of the mounting base plate 1. The discharge guide platform 6 is located below the connection between the first moving drying hood 4 and the second moving drying hood 5. This facilitates the separation between the first moving drying hood 4 and the second moving drying hood 5 under the action of the moving support mechanism 3, enabling the dried grains to be discharged to the outside, allowing the grains to fall inside the discharge guide platform 6 and be discharged to both sides of the mounting base plate 1.
[0033] Working principle of the drum-type grain dryer: During use, the grains are placed inside the feeding hopper 28, so that the agglomerated grains can be between the feeding hopper 28 and the material conveying cylinder 25. When the second motor 26 drives the spiral feeding roller 27, the spiral feeding roller 27 can strip and break the grains inside the feeding hopper 28 and the material conveying cylinder 25, reducing the volume of the agglomerated grain mass, so that the grains can be conveyed inside the material conveying cylinder 25 into the interiors of the first moving drying hood 4 and the second moving drying hood 5. At the same time, the heating ring 11 can heat, and the exhaust fan 34 can pump air to increase the temperature inside the first moving drying hood 4 and the second moving drying hood 5. At the same time, the third motor 30 can drive the rotating mounting rod 31 and the stirring arm 32, so that the stirring arm 32 can strike the grains inside the first moving drying hood 4 and the second moving drying hood 5, so that the stirring arm 32 can disperse the grains. At the same time, the first motor 21 drives the driving gear 22, and then makes the fixed locking teeth 20 rotate, so as to drive the first moving drying hood 4 and the second moving drying hood 5 to rotate, so that the first moving drying hood 4 and the second moving drying hood 5 rotate in the opposite direction to the stirring arm 32, so as to stably dry the grains. When the drying of the grains is completed, then the fourth motor 37 drives the threaded rod 36, so that the connecting moving block 35 can move on the outer surface of the threaded rod 36, driving the moving mounting plate 12, the universal wheels 13, the support mounting arm 14, the first movable roller 15, the fixed support column 16, the connecting mounting bottom block 17, the fixed mounting arm 18, the second movable roller 19, the first guiding and limiting ring 7, the second guiding and limiting ring 8 and the first moving drying hood 4 to move, so that the first moving drying hood 4 and the second moving drying hood 5 are separated from each other. At this time, the grains inside the first moving drying hood 4 and the second moving drying hood 5 can fall downward, and the grains can fall on the top of the discharge guiding platform 6, and under the action of the discharge guiding platform 6, the grains can be guided and discharged. The overall structure is simple and the operation is convenient and fast.
