Description

Technical Field

[0001] The present invention belongs to the technical field of corn seed drying, and specifically relates to a drying device for corn seed processing. Background Art

[0002] A drying device for corn seed processing is a device used to dry corn seeds and reduce their moisture content. The drying process can effectively prevent the seeds from mildewing and rotting, and ensure the germination rate and storage period of the seeds. Since the excessive water content of corn seeds will affect their storage and germination quality, the drying device is a very crucial link in the processing process.

[0003] In the existing drying device for corn seed processing, when performing drying treatment, on the one hand, the corn seeds are combined with hot air and dried during the reciprocating turning process. In fact, the stacking situation of the seeds during the turning process is serious, and it is difficult to achieve uniform drying. On the other hand, the internal water content of different seeds is different. At different drying speeds or the same drying speed, it is still impossible to ensure that all corn seeds can be completely dried within the same time. Some seeds, due to their low water content and high drying treatment intensity, can be completely dried first during the drying process. However, after drying, they cannot be separated and are still dried together with other corns in the drying system, resulting in over-drying of the corn seeds, damaging the activity of the corn seeds, affecting subsequent use, and greatly reducing the actual activity rate after drying, with poor comprehensive drying effect.

[0030] As Figures 1 to 9 shown, the embodiment of the present invention provides a drying device for processing corn seeds, including a support frame 1. The top of the support frame 1 is respectively fixedly provided with a storage cylinder 2 and an assembly cylinder assembly 3. A separation cylinder assembly 4 is arranged between the storage cylinder 2 and the assembly cylinder assembly 3. The bottom of the storage cylinder 2 is fixedly communicated with a circulating conveying portion 8, and the discharge end of the circulating conveying portion 8 is communicated with the inside of the assembly cylinder assembly 3. A heating portion 6 is arranged inside the storage cylinder 2, an air supply assembly 5 is arranged outside the storage cylinder 2, a flipping assembly 9 is sleeved on the front of the assembly cylinder assembly 3, a power portion 10 is arranged on one side inside the flipping assembly 9, a first electric push rod 7 is arranged above the separation cylinder assembly 4, and the movable end of the first electric push rod 7 is fixedly connected with the separation cylinder assembly 4. A linkage seal 11 is arranged inside the assembly cylinder assembly 3. The assembly cylinder assembly 3 is kept inclined. The separation cylinder assembly 4 includes a movable cylinder 41, a damping inner sleeve 42, a convex portion 43, an arc guide plate 44 and a first spring 45. The arc guide plate 44 is fixed on the front of the assembly cylinder assembly 3. The movable cylinder 41 is located between the storage cylinder 2 and the assembly cylinder assembly 3. The first spring 45 is fixedly connected between the movable cylinder 41 and the arc guide plate 44. The damping inner sleeve 42 is fixedly sleeved in the movable cylinder 41. The convex portions 43 are distributed around the inner wall of the damping inner sleeve 42.

[0031] Embodiment 1: When in use, start the No. 1 electric push rod 7, push the movable cylinder 41 in the separation cylinder assembly 4 to move downward, and compress the spring 1 45, open the storage cylinder 2 and the assembly cylinder assembly 3, and put the corn seeds to be dried into the storage cylinder 2 along the opened storage cylinder 2. Affected by the tilted storage cylinder 2, the corn seeds are automatically pushed inside the storage cylinder 2, and part of the seeds fall into the conveying cylinder 81 along the connecting frame 83 in the circulating conveying part 8. After the loading is completed, the movable cylinder 41 is reset, the heating part 6 is started, and the heating tube starts to heat up. The temperature inside the storage cylinder 2 and the movable cylinder 41 rises, and then the air supply assembly 5 and the circulating conveying part 8 are started at the same time, and the air pump 51 in the air supply assembly 5 inputs the air volume into the air guide pipe through the ventilation sleeve 52 53, and blow to the bottom of the inner wall of the movable cylinder 41, and disperse the nearby heat forward, and at the same time, the rotating shaft 85 in the conveying cylinder 81 drives the spiral blade 86 to rotate, and conveys the corn seeds in the conveying cylinder 81 upward to the annular cavity 33 of the assembly cylinder assembly 3, and starts the power unit 10, the motor 2 101 in the power unit 10 drives the gear 102 to rotate, and makes the meshing connected gear ring 93 rotate, so that the flip assembly 9 rotates, and the rotating ring 91 in the flip assembly 9 drives the inner wall paddle 92 to rotate, and as the paddle 92 rotates upward, the corn seeds in the annular cavity 33 are moved to the top of the inner cylinder 32, and fall along the drop opening 34, and continue to slide downward after falling to the inner wall of the inner cylinder 32, and the corn seeds are moved along the distribution The damping inner sleeve 42 and the inner wall protrusion 43 in the separation barrel assembly 4 slide downwardly into the storage barrel 2, and continue to fall into the circulating conveying part 8 for conveying. The corn seeds come into contact with the hot air when falling in the assembly barrel assembly 3, completing the uniform drying of the corn seeds after dispersion. When the internal moisture of the corn seeds gradually dries and decreases, the seed weight is reduced, and the moisture ratio is greatly reduced. When the internal moisture of the corn seeds is reduced by a certain amount, when falling along the inside of the assembly barrel assembly 3, the lightweight corn seeds that roll to the damping inner sleeve 42 and the protrusion 43 are simultaneously subjected to the upward hot wind blowing, and stop sliding and remain in the damping inner sleeve 42. The corn seeds that are not completely dried slide downward, and the No. 1 electric push rod 7 is started at this time to push the separation barrel assembly Component 4 moves downward, spring 145 is compressed, movable cylinder 41 moves downward and is offset from storage cylinder 2. Under the dynamic effect, the lightweight corn seeds statically balanced on the damping inner sleeve 42 slide along the bottom of movable cylinder 41 into the arc-shaped guide plate 44. During the action, movable cylinder 41 drives sleeve rod 115 to move downward and squeezes the hydraulic oil in curved tube 114. Under the action of hydraulic pressure, push rod 113 in bottom tube 112 is pushed upward, and mounting block 111 and sealing plate 117 are driven upward to block drop opening 34, thus completing the independent separation of the dried lightweight corn seeds stabilized in separation cylinder assembly 4. Then, the drop opening 34 is reopened after being reset, and circulating conveying section 8 continues to circulate and dry the seeds that are not completely dried.

[0032] First, by utilizing the storage cylinder 2, the separation cylinder assembly 4, the assembly cylinder assembly 3, and the circulating conveyor 8, and in combination with the inclined assembly effect, a circulating drying system is formed to achieve the circulating drying of corn seeds after they are put in, enabling the seeds to continuously transfer in the system and realizing a small amount of continuous and dispersed movement. In combination with the heating unit 6 and the air supply assembly 5, uniform and effective hot air drying is carried out for the corn seeds put in small amounts and multiple times, improving the drying uniformity of the batch-input corn seeds, thereby improving the actual drying efficiency and having a good comprehensive drying effect.

[0033] In addition, by utilizing the wind direction control of the air supply assembly 5, in combination with the separation cylinder assembly 4 controlled by the first electric push rod 7, and in combination with the linkage seal 11, during the actual continuous circulating drying process, for the situation where the internal humidity of some corn seeds is small, there are some corn seeds that are dried in advance. Through the cooperation of the damping inner sleeve 42, the convex part 43, and the action of the inclined hot air, when the seeds that are dried in advance move in the circulating drying system, they actually achieve balance at the separation cylinder assembly 4 and remain stationary in the damping inner sleeve 42, temporarily blocking the continuous movement. In combination with the descending movable cylinder 41, the completely dried seeds that are stationary and circulated in the middle are guided out of the system, realizing the early separation of the completely dried corn seeds, avoiding over-drying, and improving the comprehensive drying quality.

[0034] Embodiment 2: When hot air is continuously blown into the storage cylinder 2, the continuously blown and heated hot air fills the interiors of the separation cylinder assembly 4 and the assembly cylinder assembly 3, and enters the annular cavity 33 along the side through-hole 35, drying the seeds conveyed and flipped in the annular cavity 33 with hot air. At the same time, the hot air is further guided to be input into the conveying cylinder 81 along the top of the circulating conveyor 8 and finally output along the bottom hole 84.

When the air supply assembly 5 disperses and blows out the heat from the heating unit 6, in combination with the side through-hole 35, the hot air is dispersed in the system. Besides carrying out hot air drying between the assembly cylinder assembly 3 and the storage cylinder 2, the hot air is also introduced into the interiors of the assembly cylinder assembly 3 and the flipping assembly 9, and at the same time into the circulating conveyor 8, and the movement direction of the hot air is opposite to the circulating drying direction, fully guiding and filling the hot air to all parts of the circulating system, completing the full hot air drying of the dispersed corn seeds everywhere. At the same time, in combination with the bottom hole 84, the discharge of impurity particles and the discharge of hot air during the circulating conveying process are completed, realizing the screening of impurities and strengthening the circulating heating and drying.

[0036] Embodiment 3: After the relative drying process of the subsequent seeds is completed, the air supply component 5 is closed, and the second electric push rod 116 in the linkage seal 11 is started to drive the sealing plate 117 to move downward.

[0046] Working principle and usage process of the present invention: When in use, start the first electric push rod 7 to push the movable cylinder 41 in the separation cylinder assembly 4 downward, compress the first spring 45, open the storage cylinder 2 and the assembly cylinder assembly 3, and put the corn seeds to be dried into the storage cylinder 2 along the opened storage cylinder 2. Affected by the inclined storage cylinder 2, the corn seeds are automatically pushed together inside the storage cylinder 2, and some seeds fall into the conveying cylinder 81 along the connecting frame 83 in the circulating conveying part 8. After the feeding is completed, reset the movable cylinder 41, start the heating part 6, and the heating tube starts to heat up, and the temperatures inside the storage cylinder 2 and the movable cylinder 41 increase. Subsequently, start the air supply assembly 5 and the circulating conveying part 8 simultaneously. The air pump 51 in the air supply assembly 5 inputs the air volume through the ventilation sleeve 52 into the air guide pipe 53 and blows it towards the bottom of the inner wall of the movable cylinder 41, and disperses the nearby heat forward. At the same time, the rotating shaft 85 in the conveying cylinder 81 drives the spiral blade 86 to rotate, and conveys the corn seeds in the conveying cylinder 81 upward to the annular cavity 33 of the assembly cylinder assembly 3. And start the power part 10. The second motor 101 in the power part 10 drives the gear 102 to rotate, and makes the meshing-connected gear ring 93 rotate, thereby making the flipping assembly 9 rotate. The rotating ring 91 in the flipping assembly 9 drives the inner wall paddle 92 to rotate. As the paddle 92 rotates upward, the corn seeds in the annular cavity 33 are dialed above the inner cylinder 32 and fall along the material dropping port 34, and continue to slide downward after falling onto the inner wall of the inner cylinder 32. The corn seeds slide downward along the damping inner sleeve 42 and the inner wall convex part 43 in the separation cylinder assembly 4 and fall into the storage cylinder 2, and continue to fall into the circulating conveying part 8 for conveying. The corn seeds are in contact with the hot air when dropping in the assembly cylinder assembly 3, and the uniform drying of the dispersed corn seeds is completed. When the internal moisture of the corn seeds gradually dries and decreases, the seed quality decreases, and the moisture ratio greatly decreases. When the internal moisture of the corn seeds decreases by a certain amount, when falling along the inside of the assembly cylinder assembly 3, the lightweight corn seeds that roll to the damping inner sleeve 42 and the convex part 43 are simultaneously blown by the hot air inclined upward, stop sliding and remain in the damping inner sleeve 42. The corn seeds that are not completely dried slide downward. At this time, start the first electric push rod 7 to push the separation cylinder assembly 4 downward, the first spring 45 is compressed, the movable cylinder 41 moves downward and is staggered from the storage cylinder 2. Under the dynamic effect, the lightweight corn seeds statically balanced on the damping inner sleeve 42 slide along the bottom of the movable cylinder 41 into the arc-shaped guiding plate 44. And during the action, the movable cylinder 41 drives the sleeve rod 115 to move downward, and squeezes the hydraulic oil in the curved pipe 114. Under the hydraulic action, the push rod 113 in the bottom pipe 112 is pushed upward, and drives the mounting block 111 and the sealing plate 117 to move upward, and blocks the material dropping port 34, completing the independent separation of the dried lightweight corn seeds stably in the separation cylinder assembly 4. Subsequently, reset, the material dropping port 34 is reopened, and the circulating conveying part 8 continues to perform cyclic drying treatment on the seeds that are not completely dried;When hot air is continuously blown into the storage cylinder 2, the continuously blown and heated hot air fills the interiors of the separation cylinder assembly 4 and the assembly cylinder assembly 3, and enters the annular cavity 33 along the side through-hole 35, drying the seeds being flipped and conveyed in the annular cavity 33 with hot air. At the same time, the hot air is further guided to be input into the conveying cylinder 81 along the top of the circulating conveying part 8, and finally output along the bottom hole 84. During this process, the impurity particles mixed in the seeds fall out along the bottom hole 84, realizing the full-path hot air guidance during the circulating conveying process and completing uniform heating and drying. When the subsequent relative drying process of the seeds is completed, the air supply assembly 5 is closed, and the second electric push rod 116 in the linkage seal 11 is started to drive the sealing plate 117 to move downward. The distance between the sealing plate 117 and the material dropping port 34 increases. Then, the first electric push rod 7 is started again to push the movable cylinder 41 to move downward. The end face of the movable cylinder 41 is staggered from the end face of the storage cylinder 2. At this time, the sealing plate 117 does not seal the material dropping port 34. Keeping the circulating conveying part 8 and the power part 10 started, the corn seeds are continuously conveyed into the upper assembly cylinder assembly 3 and fall out along the material dropping port 34. The corn seeds continuously fall out and slide down along the guidance of the movable cylinder 41 into the arc-shaped guiding plate 44, completing automatic and comprehensive discharging.
