Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, and more specifically, to a drying device for grain processing. Background Technology
[0002] In the grain processing sector, drying is a crucial step in ensuring the quality of grain storage and processing. However, existing drying technologies have some limitations that affect drying efficiency and grain quality.
[0003] First, traditional natural air drying relies on natural conditions, such as sunlight and wind, to evaporate the moisture in the grain. This drying process is uncontrollable, greatly affected by weather changes, and is time-consuming and labor-intensive. In rainy weather or in environments with high humidity, the grain may not be dried sufficiently, thus increasing the risk of mold and sprouting, affecting the storage period and quality of the grain.
[0004] Secondly, some modern drying equipment uses fans and pipes to accelerate the drying process of grain. These devices mechanically deliver hot air into the grain to improve drying efficiency. However, existing fan and pipe designs usually use smooth inner walls. While this design helps reduce friction and damage to the grain in the pipes, it does not allow for flexible control of the wind speed. The instability of the wind speed will affect the drying effect and may lead to uneven drying of the grain, or even over-drying or under-drying.
[0005] In addition, some drying equipment is equipped with wind speed control devices, but these devices have a relatively simple structure and low stability. During the drying process, the vibration of the equipment or pipeline may cause the wind speed control device to loosen or shift, thereby changing the preset wind speed. This unstable wind speed will not only affect the drying effect, but may also damage the grain and increase the drying cost. Utility Model Content

[0033] Please see Figures 1-7 A grain drying device includes a drying chamber 1, characterized in that: a drying device is installed in the drying chamber 1, and a speed regulating device is installed on the outside of the drying chamber 1. The speed regulating device includes a fixed pipe 2, an adjusting block 3, an adjusting sleeve 4, a control sleeve 5, a rigid pipe 6, a mating sleeve 7, and an adjusting rod 8. The adjusting block 3 is movably installed in the fixed pipe 2. The adjusting sleeve 4 is threaded onto the outside of the adjusting rod 8. The two ends of the control sleeve 5 are rotatably connected to the fixed pipe 2 and the rigid pipe 6, respectively. The mating sleeve 7 is installed in the fixed pipe 2. The adjusting rod 8 is fixedly installed inside the control sleeve 5. A locking mechanism is installed on the outside of the fixed pipe 2. The locking mechanism includes a self-locking sleeve 9, a return sleeve 10, an arc groove 11, a circular groove 12, and a return... The system includes a spring 13, a locking plate 14, a top rod 15, a self-locking groove 16, a self-locking rod 17, a connecting block 18, and a return block 19. The self-locking sleeve 9 is slidably sleeved on the outside of the fixed tube 2, and the return sleeve 10 is rotatably sleeved on the outside of the fixed tube 2. An arc-shaped groove 11 is opened on the return sleeve 10, and a circular groove 12 is opened at one end of the arc-shaped groove 11. The two ends of the return spring 13 are respectively connected to the return block 19 and the connecting block 18. The locking plate 14 is set on the outside of the top rod 15, and the top rod 15 is fixedly connected to one side of the self-locking sleeve 9. Multiple self-locking grooves 16 are opened on the outside of the fixed tube 2. The self-locking rod 17 is slidably set on the self-locking sleeve 9. The connecting block 18 is fixedly connected to the outside of the fixed tube 2, and the return block 19 is fixedly connected to one side of the return sleeve 10.
[0034] The fitting sleeve 7 has a sliding groove 20, and the adjusting block 3 is connected to a sliding block 21 on one side. The sliding block 21 is slidably disposed in the sliding groove 20. The fitting sleeve 7 is connected to a slider 22 on the outside. The fixing tube 2 has a sliding groove 23 on the inside, and the sliding groove 23 is adapted to the slider 22.
[0035] An inclined groove 24 is provided inside the fixed tube 2, and an inclined plate 25 is connected to one side of the adjusting block 3. The inclined plate 25 is slidably disposed in the inclined groove 24.
[0036] A push spring 26 is connected to one side of the adjusting block 3, and a top block 27 is connected to the other end of the push spring 26.
[0037] A push spring 28 is sleeved on the outside of the push rod 15. One end of the push spring 28 is in contact with the return sleeve 10, and the other end of the push spring 28 is connected to the self-locking sleeve 9. A connecting spring 29 is connected to the outside of the control sleeve 5. One end of the self-locking rod 17 is connected to the outer wall of the control sleeve 5 through the connecting spring 29.
[0038] In this embodiment, when the wind speed needs to be adjusted according to requirements, the return sleeve 10 is first rotated, causing the return block 19 to move. Then, the return block 19 cooperates with the connecting block 18 to compress the return spring 13, and the return sleeve 10 drives the arc groove 11 and the circular groove 12 to rotate. When the return spring 13 is compressed to its limit, the circular groove 12 moves to a position concentric with the locking plate 14, pushing the self-locking sleeve 9. The self-locking sleeve 9 drives the top rod 15 and the locking plate 14 to pass through the circular groove 12. At the same time, the self-locking sleeve 9 cooperates with the return sleeve 10 to compress the push spring 28 sleeved on the outside of the top rod 15. When the push spring 28 is compressed to its limit, the corresponding locking plate 14 passes through the circular groove 12 and reaches the other side of the return sleeve 10. Then, the return sleeve 10 is released. 0. The return spring 13 pushes the return block 19 to reset, then the return block 19 drives the return sleeve 10 to reset, and then the return sleeve 10 drives the arc groove 11 and the circular groove 12 to reset, so that the push rod 15 slides into the arc groove 11. Then the self-locking sleeve 9 is locked on one side of the return sleeve 10 through the cooperation of the push rod 15 and the corresponding locking plate 14. At this time, the outer end of the self-locking rod 17 will lose the limit of the inner wall of the return sleeve 10. Then the control sleeve 5 is rotated, and the control sleeve 5 will drive the self-locking rod 17 to rotate. Then the side wall of the self-locking groove 16 will squeeze one end of the self-locking rod 17. Due to the rounded corner structure design of the edge of the self-locking groove 16 and the end of the self-locking rod 17, one end of the self-locking rod 17 will slide out of the self-locking groove 16. Then the other end of the self-locking rod 17 will drive the connecting spring 29 to stretch. Meanwhile, the control sleeve 5 will drive the inner adjusting rod 8 to rotate. Since the adjusting sleeve 4 is threadedly fitted onto the outside of the adjusting rod 8, and the slider 22 and the groove 23 limit the movement of the mating sleeve 7, the mating sleeve 7 and the adjusting sleeve 4 will not rotate. Then, the adjusting sleeve 4 will drive the mating sleeve 7 to slide along the adjusting rod 8, and the adjusting sleeve 4 will drive the slider 22 to slide along the groove 23. Then, the mating sleeve 7 will drive the adjusting block 3 to move through the sliding groove 20 and the sliding block 21. Then, the adjusting block 3 will drive the inclined plate 25 to slide along the inclined groove 24. Due to the inclined structure design of the inclined plate 25 and the inclined groove 24, when the inclined plate 25 slides along the inclined groove 24, the inclined plate 25 will drive the adjusting block 3 to converge or spread inward. Then, the adjusting block 3 will drive one side of the connecting... The sliding block 21 slides along the sliding groove 20. When the adjusting block 3 moves inward, multiple top blocks 27 first abut together, and then the push spring 26 is compressed, causing the gap of the push spring 26 to change. The movement of the adjusting block 3 changes the volume of air passing through, thereby changing the air passing speed. The change in the gap of the push spring 26 also changes the volume of air passing through, thereby further changing the air passing speed. When the wind speed is adjusted appropriately, the connecting spring 29 drives the self-locking rod 17 to reset, causing the other end of the self-locking rod 17 to engage in the corresponding self-locking groove 16. Then, the return sleeve 10 is rotated again, causing the return sleeve 10 to drive the return block 19 to move again. Then, the return block 19 cooperates with the connecting block 18 to compress the return spring 13 again.Furthermore, the return sleeve 10 will again drive the arc groove 11 and the circular groove 12 to move. When the circular groove 12 moves to a position concentric with the clamping plate 14, the push spring 28 pushes the self-locking sleeve 9 to reset. Then, the self-locking sleeve 9 will drive the push rod 15 and the clamping plate 14 to slide and reset. After the push spring 28 has fully reset, the return sleeve 10 is released, and the return spring 13 will push the return block 19 to reset. Then, the return block 19 will again drive the return sleeve 10 to reset, and then the return sleeve 10 will drive the arc groove 11 and the circular groove 12 to reset. When the circular groove 12 and the arc-shaped groove 11 move to a position no longer corresponding to the top rod 15 and the clamping plate 14, the top rod 15 will cooperate with the return sleeve 10 to provide stable support for the self-locking sleeve 9, preventing it from sliding. Then, the inner wall of the self-locking sleeve 9 will again limit the outer end of the self-locking rod 17, preventing it from moving. Finally, the self-locking rod 17 will cooperate with the self-locking groove 16 to stably limit the control sleeve 5, preventing it from rotating, thus ensuring the stability after wind speed adjustment.
[0039] Please see Figures 1-4 As one embodiment of the drying device: the drying device includes a fan 30, an air duct 31 and an air chamber 32. The fan 30 is detachably installed on the outside of the drying chamber 1. The air duct 31 is connected to one end of the air chamber 32 and the fan 30. The air chamber 32 is fixedly installed on the outside of the drying chamber 1.
[0040] The top of the drying chamber 1 is connected to the feeding chamber 33, the bottom of the drying chamber 1 is provided with the discharge port 34, the drying chamber 1 is provided with the cavity 35, the air chamber 32 is provided with the electric heating tube 36 which can be detached, and the inner wall of the drying chamber 1 is provided with the air inlet 37.
[0041] The drying chamber 1 is equipped with a baffle plate 38 and a flow divider plate 39. A flow guide plate 40 is provided below one of the baffle plates 38.
[0042] More specifically, when the equipment is needed, first turn on the electric heating element 36 for preheating, then turn on the fan 30 to blow natural air into the air duct 31, and then blow the natural air into the air chamber 32 through the air duct 31. The natural air will then exchange heat with the electric heating element 36 to become drying hot air, which will then enter the cavity 35 and enter the drying chamber 1 through the air inlet 37 on the side wall of the cavity 35. Then, the grain will be conveyed into the drying chamber 1 through the feeding hopper 33. The grain will first come into contact with the baffle plate 38 at the top of the drying chamber 1, which will disperse the grain and reduce its speed when entering the drying chamber 1. Then, the grain will pass through the baffle plate 38. The grain falls downward through the grooves on plate 38, causing it to come into contact with multiple diversion plates 39. After hitting the diversion plates 39, the grain spreads out and its falling speed decreases again, increasing the residence time of the grain inside the drying chamber 1, thus ensuring thorough drying. Due to the triangular structure design of the diversion plates 39, the grain can be effectively prevented from flying into the cavity 35 from the air inlet 37. After drying, the grain comes into contact with the baffle plate 38 set below the diversion plates 39, and then falls to the discharge port 34 through the guide plate 40. From there, it reaches the external conveying equipment, thus transporting the dried grain to the next process.
[0043] In summary, during the use or operation of the overall equipment: when the wind speed needs to be adjusted according to requirements, firstly, rotate the return sleeve 10, causing the return sleeve 10 to move the return block 19. Then, the return block 19, in conjunction with the connecting block 18, will compress the return spring 13. Simultaneously, the return sleeve 10 will cause the arc-shaped groove 11 and the circular groove 12 to rotate. When the return spring 13 is compressed to its limit, the circular groove 12 moves to a position concentric with the clamping plate 14, pushing the self-locking sleeve 9. The self-locking sleeve 9 will then cause the push rod 15 and the clamping plate 14 to pass through the circular groove 12. At the same time, the self-locking sleeve 9, in conjunction with the return sleeve 10, will compress the push spring 28 sleeved on the outside of the push rod 15. When the push spring 28 is compressed to its limit, the corresponding clamping plate 14 passes through the circular groove 12 and reaches the other side of the return sleeve 10. After releasing the return sleeve 10, the return spring 13 pushes the return block 19 to reset, then the return block 19 drives the return sleeve 10 to reset, and then the return sleeve 10 drives the arc groove 11 and the circular groove 12 to reset, so that the push rod 15 slides into the arc groove 11. Then the self-locking sleeve 9 is locked on one side of the return sleeve 10 through the cooperation of the push rod 15 and the corresponding locking plate 14. At this time, the outer end of the self-locking rod 17 will lose the limit of the inner wall of the return sleeve 10. Then, rotate the control sleeve 5, and the control sleeve 5 will drive the self-locking rod 17 to rotate. Then the side wall of the self-locking groove 16 will squeeze one end of the self-locking rod 17. Due to the rounded corner structure design of the edge of the self-locking groove 16 and the end of the self-locking rod 17, one end of the self-locking rod 17 will slide out of the self-locking groove 16. Then the other end of the self-locking rod 17 will drive the connecting spring 2. 9. During the stretching process, the control sleeve 5 will drive the inner adjusting rod 8 to rotate. Since the adjusting sleeve 4 is threadedly fitted onto the outside of the adjusting rod 8, and the slider 22 and the groove 23 limit the movement of the mating sleeve 7, the mating sleeve 7 and the adjusting sleeve 4 will not rotate. Then, the adjusting sleeve 4 will drive the mating sleeve 7 to slide along the adjusting rod 8, and the adjusting sleeve 4 will drive the slider 22 to slide along the groove 23. Then, the mating sleeve 7 will drive the adjusting block 3 to move through the sliding groove 20 and the sliding block 21. Then, the adjusting block 3 will drive the inclined plate 25 to slide along the inclined groove 24. Due to the inclined structure design of the inclined plate 25 and the inclined groove 24, when the inclined plate 25 slides along the inclined groove 24, the inclined plate 25 will drive the adjusting block 3 to converge or spread inward. Then, the adjusting block 3 will drive a... The side-connected sliding block 21 slides along the sliding groove 20. When the adjusting block 3 converges inward, multiple top blocks 27 first abut together, and then the push spring 26 is compressed, causing the gap of the push spring 26 to change. The movement of the adjusting block 3 changes the volume of air passing through, thereby changing the air passing speed. The change in the gap of the push spring 26 also changes the volume of air passing through, thereby further changing the air passing speed. When the wind speed is adjusted appropriately, the connecting spring 29 drives the self-locking rod 17 to reset, causing the other end of the self-locking rod 17 to engage in the corresponding self-locking groove 16. Then, the return sleeve 10 is rotated again, causing the return sleeve 10 to drive the return block 19 to move again. Then, the return block 19 cooperates with the connecting block 18 to compress the return spring 13 again.Furthermore, the return sleeve 10 will again drive the arc groove 11 and the circular groove 12 to move. When the circular groove 12 moves to a position concentric with the clamping plate 14, the push spring 28 pushes the self-locking sleeve 9 to reset. Then, the self-locking sleeve 9 will drive the push rod 15 and the clamping plate 14 to slide and reset. After the push spring 28 has fully reset, the return sleeve 10 is released, and the return spring 13 will push the return block 19 to reset. Then, the return block 19 will again drive the return sleeve 10 to reset, and then the return sleeve 10 will drive the arc groove 11 and the circular groove 12 to reset. When the circular groove 12 and the arc-shaped groove 11 move to a position no longer corresponding to the top rod 15 and the clamping plate 14, the top rod 15 will cooperate with the return sleeve 10 to provide stable support for the self-locking sleeve 9, preventing it from sliding. Then, the inner wall of the self-locking sleeve 9 will again limit the outer end of the self-locking rod 17, preventing it from moving. Finally, the self-locking rod 17 will cooperate with the self-locking groove 16 to stably limit the control sleeve 5, preventing it from rotating, thus ensuring the stability after wind speed adjustment.
[0044] When the equipment is needed, first turn on the electric heating element 36 for preheating, then turn on the fan 30 to blow natural air into the air duct 31, and then blow the natural air into the air chamber 32 through the air duct 31. The natural air will then exchange heat with the electric heating element 36 and become drying hot air. The hot air will then enter the cavity 35 and then enter the drying chamber 1 through the air inlet 37 on the side wall of the cavity 35. Then, the grain will be conveyed into the drying chamber 1 through the feeding hopper 33. The grain will first come into contact with the baffle plate 38 at the top of the drying chamber 1, which will disperse the grain and reduce the speed at which it enters the drying chamber 1. Then, it will pass through the baffle plate 38. The grain falls downward through the groove on plate 8, causing it to come into contact with multiple diversion plates 39. After hitting the diversion plates 39, the grain spreads out and its falling speed is reduced again, increasing the residence time of the grain inside the drying chamber 1, thus ensuring thorough drying. Due to the triangular structure design of the diversion plates 39, the grain can be effectively prevented from flying into the cavity 35 from the air inlet 37. After drying, the grain comes into contact with the baffle plate 38 set below the diversion plates 39, and then falls to the discharge port 34 through the guide plate 40. From the discharge port 34, the grain reaches the external conveying equipment, thus transporting the dried grain to the next process.
