Description

Technical Field

[0001] The invention belongs to the technical field of corn seed drying, in particular to a drying device for corn seed processing. Background Art

[0002] The 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 mold and rot, and ensure the germination rate and storage period of the seeds. Since too high a moisture content in corn seeds will affect their storage and germination quality, the drying device is a very critical link in the processing process.

[0003] The drying device for corn seed processing in the prior art, when performing drying treatment, on the one hand, uses the combination of corn seeds and hot air to complete the drying treatment in the reciprocating turning process. In fact, the seeds are seriously piled up in the turning process, and it is difficult to achieve uniform drying. On the other hand, different seeds have different internal water contents. At different drying speeds or the same drying speed, it is still impossible to ensure that all corn seeds can be fully dried within the same time. Some seeds can be fully dried first in the drying process due to their low water content and high drying intensity. However, they cannot be separated after drying and are still dried together with other corns in the drying system, causing the corn seeds to be over-dried, destroying the activity of the corn seeds, affecting subsequent use, and the actual activity rate after drying is greatly reduced, and the overall drying effect is not good.

The movable end of the No. 1 electric push rod 7 is fixedly connected to the separation cylinder assembly 4. A linkage seal 11 is provided inside the assembly cylinder assembly 3. The assembly cylinder assembly 3 remains tilted. The separation cylinder assembly 4 comprises a movable cylinder 41, a damping inner sleeve 42, a protrusion 43, an arc guide plate 44 and a 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 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 protrusions 43 are distributed around the inner wall of the damping inner sleeve 42.

[0021] 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.

[0022] Firstly, by utilizing the storage cylinder 2, the separation cylinder assembly 4, the assembly cylinder assembly 3 and the circulating conveying part 8, in coordination with the inclined assembly effect, a circulating drying system is formed to realize the circulating drying of the corn seeds after they are put in, so that the seeds are continuously transferred in the system and a small amount of continuous dispersed movement is realized. In coordination with the heating part 6 and the air supply assembly 5, uniform and effective wind-heat drying is performed on the corn seeds that are put in a small amount and multiple times, thereby improving the drying uniformity of the corn seeds put in batches, thereby improving the actual drying efficiency and achieving a good comprehensive drying effect.

[0023] In addition, by utilizing the wind direction control of the air supply component 5, in conjunction with the separation cylinder component 4 controlled by the No. 1 electric push rod 7, and in conjunction with the linkage seal 11, in the actual continuous circulation drying process, in view of the situation that the internal humidity of some corn seeds is low, some corn seeds are dried in advance. By cooperating with the damping inner sleeve 42 and the protrusion 43 and the inclined hot air, the seeds that have been dried in advance are actually balanced at the separation cylinder component 4 when moving in the circulating drying system, and are stationary in the damping inner sleeve 42, temporarily blocking the continuous movement, and cooperating with the descending movable cylinder 41, the completely dried seeds that are stationary in the middle of the circulation are guided out of the system, so as to achieve the early separation of the completely dried corn seeds, avoid overdrying, and improve the overall drying quality.

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, 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 passes the air volume through the ventilation sleeve 52 The corn seeds in the conveying cylinder 81 are conveyed to the annular cavity 33 of the assembly cylinder assembly 3, and the power unit 10 is started.

When the corn seeds fall in the assembly cylinder assembly 3, they come into contact with the hot air, completing the uniform drying of the corn seeds after dispersion. When the moisture inside the corn seeds gradually dries and decreases, the seed weight is reduced, and the moisture ratio is greatly reduced. When the moisture inside the corn seeds is reduced by a certain amount, when they fall along the inside of the assembly cylinder 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.
