Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a horizontal lifting vertical seed dryer. Background Technology

[0002] Seeds need a suitable amount of moisture to sustain their life activities, but excessive moisture content can cause them to easily mold, spoil, and rot during storage. Drying can reduce the moisture content of seeds to a safe storage range. For example, the safe storage moisture content for cereal seeds is generally around 13%-15%. When the seed moisture content is reduced to this level, the growth and reproduction of microorganisms and the seed's own respiration are inhibited, thereby extending the seed's shelf life.

[0003] Traditionally, seeds are dried by sun-drying, which is time-consuming and labor-intensive. Seed dryers, on the other hand, are highly efficient drying equipment with advantages such as fast drying speed and low labor intensity for workers. For example, the existing technology CN113180105B proposes a tower-type grain drying device, which puts seeds in from top to bottom to achieve seed drying.

[0004] However, existing vertical drying equipment involves feeding seeds from the top port, dispersing them through a stirring rod, and then simultaneously drying them using a fan. While this method can dry the seeds, the seeds fall relatively quickly, have a short exposure time to hot air, and the drying effect is relatively poor. Furthermore, the seeds are easily broken due to being struck by the stirring rod. Therefore, we provide a horizontal lifting vertical seed dryer to solve the aforementioned problems.

A second transmission belt is installed between the two second pulleys.

[0011] As a further improvement of this utility model, the C-type bucket elevator is provided with a discharge port on one side of its upper end.

[0012] As a further embodiment of this utility model: the driving assembly includes a central lever block, which is fixedly connected to the middle of the upper end face of the rack.

[0029] 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.

[0030] Please see Figures 1-7In this embodiment of the present invention, a horizontal lifting vertical seed dryer includes a drying box 2 and a C-type bucket elevator 1. The drying box 2 is installed inside the C-type bucket elevator 1. The upper side of the C-type bucket elevator 1 is provided with a discharge port 8. The lower end of the drying box 2 is provided with a discharge pipe 19, the lower end of which is connected to the lower horizontal section of the drying box 2. The lower horizontal section of the C-type bucket elevator 1 is also provided with a feed port 9. The drying box 2 is provided with three temporary holding components 6 from top to bottom to slow down the falling speed of the seeds. Inside the drying box 2, below the sliding rod 18 and the ventilation mesh plate 609, there are several diamond-shaped dispersing rods 7 for dispersing the seeds. The diamond-shaped dispersing rods 7 can disperse the seeds when they fall and also disperse the airflow from bottom to top.

[0031] The upper end of the drying chamber 2 is provided with a feeding assembly for dispersing seeds. The feeding assembly includes a seed inlet 11, which is fixedly connected to the middle of the upper end of the drying chamber 2. A flexible tube 15 is connected to the lower end of the seed inlet 11, and a seed dispersing inlet 14 is connected to the lower end of the flexible tube 15. Two sliding rods 18 are fixedly connected to the upper end of the drying chamber 2. The two sides of the seed dispersing inlet 14 are slidably connected to the sliding rods 18 respectively. A reciprocating assembly for driving the seed dispersing inlet 14 to reciprocate is provided on one side of the drying chamber 2. The reciprocating assembly includes a drive shaft 17, which is rotatably connected to one side of the upper end of the drying chamber 2. A shaft frame 27 is fixedly connected to one side of the upper end of the interior of the drying chamber 2. A turntable 16 is rotatably connected to the end of the shaft frame 27. A bevel gear 28 is fixedly connected to the upper end of the connecting shaft of the turntable 16 and the end of the drive shaft 17 near the turntable 16. Two bevel gears 28 mesh with each other. A connecting rod 10 is connected to the turntable 16 away from the center. The end of the connecting rod 10 away from the turntable 16 is rotatably connected to the seed dispensing port 14. A drive motor 13 is also installed on the upper side of one side of the drying chamber 2. A second pulley 29 is installed on the output end of the drive motor 13 and the end of the drive shaft 17 that passes through the drying chamber 2. A second transmission belt 5 is installed between the two second pulleys 29. During operation, the drive motor 13 drives the second pulleys 29 to rotate, causing the drive shaft 17 to rotate. The rotation of the drive shaft 17 drives the bevel gears 28 to rotate. The rotation of the bevel gears 28 drives the turntable 16 to rotate. The rotation of the turntable 16 drives the connecting rod 10 to move. The movement of the connecting rod 10 drives the seed dispensing port 14 to move back and forth. The reciprocating movement of the seed dispensing port 14 can evenly sprinkle the seeds entering the drying chamber 2 into the interior of the drying chamber 2.

[0032] The lower end of the drying chamber 2 is equipped with a heater for drying the seeds. The heater includes a hot air blower 3, which is located on both sides of the drying chamber 2. The output end of the hot air blower 3 is connected to a ventilation pipe 4, and the upper end of the ventilation pipe 4 is connected to an air inlet hood 30. The drying chamber 2 has several air inlets inside the air inlet hood 30. When working, the hot air blower 3 is activated to send air to the ventilation pipe 4. The hot air enters the air inlet hood 30 through the ventilation pipe 4 and then enters the drying chamber 2 through the air inlets to dry the seeds.

[0033] The temporary holding component 6 includes several evenly arranged ventilation mesh panels 609. Each ventilation mesh panel 609 has an end shaft 601 fixedly connected to both ends. The end shaft 601 is rotatably connected to the drying chamber 2. Gears 602 are fixedly connected to the positions where the end shaft 601 extends out of the drying chamber 2. T-shaped slide rails 610 are fixedly connected to the drying chamber 2 above the gears 602 on one side. Racks 603 are slidably connected to the T-shaped slide rails 610, and the racks 603 mesh with the gears 602. The drying chamber 2... One side is also equipped with a drive assembly for driving the rack 603 to reciprocate and rotate the ventilation mesh plate 609. During operation, the ventilation mesh plate 609 can be laid flat in a horizontal state to block the seeds. The drive assembly can make the ventilation mesh plate 609 rotate intermittently, so that the seeds can stay on the ventilation mesh plate 609 for a short time. At the same time, the three sets of temporary holding components 6 can make the seeds stay multiple times, thereby effectively increasing the residence time of the seeds in the drying box 2, so that the seeds are fully dried.

[0034] The driving assembly includes a central shift block 606, which is fixedly connected to the middle of the upper end face of the rack 603. Fixed blocks 605 are fixedly connected to both ends of the rack 603. Two spring seats 608 are fixedly connected to the drying chamber 2 above the rack 603. A limiting block 607 matching the spring seats 608 is provided above the rack 603 in the drying chamber 2. Return springs 604 are installed between the fixed blocks 605 and the spring seats 608. A shifting assembly for driving the three racks 603 to move alternately is also provided on one side of the drying chamber 2. The shifting assembly includes a second synchronous pulley 31, a double-groove synchronous pulley 21, and a third synchronous pulley 603. A first synchronous pulley 25, a second synchronous pulley 31, a double-grooved synchronous pulley 21 and a first synchronous pulley 25 are rotatably connected from top to bottom above a rack 603. A synchronous belt 20 is installed between the second synchronous pulley 31, the first synchronous pulley 25 and the double-grooved synchronous pulley 21. A third paddle 23 is fixedly connected to the second synchronous pulley 31. A second paddle 24 is fixedly connected to the double-grooved synchronous pulley 21. A first paddle 22 is fixedly connected to the first synchronous pulley 25. A first pulley 12 is installed on the drive shaft 17 and the connecting shaft of the second synchronous pulley 31. A first transmission belt 26 is installed between the two first pulleys 12.

[0035] During operation, the rotation of the drive shaft 17 drives the first transmission belt 26 and the first pulley 12 to operate. The operation of the first pulley 12 drives the second synchronous pulley 31, which drives the synchronous belt 20. The synchronous belt 20 drives the double-groove synchronous pulley 21, which drives the first synchronous pulley 25. When the second synchronous pulley 31, the double-groove synchronous pulley 21, and the first synchronous pulley 25 rotate, they can respectively drive the third paddle 23, the second paddle 24, and the first paddle 22 to operate. The third paddle 23, the second paddle 24, and the first paddle 22 can respectively drive the intermediate paddle block 606 to move. The movement of the intermediate paddle block 606 can drive the rack 603, which can drive the gear 602 to rotate. The rotation of the gear 602 can drive the ventilation mesh plate 609 to flip over, flipping the seeds down. After the third paddle 23 disengages from the intermediate paddle block 606, the rack 603 resets under the action of the return spring 604, so that the ventilation mesh plate 609 returns to a horizontal state.

[0036] The included angle between the third paddle 23, the second paddle 24 and the first paddle 22 is 120 degrees. Since there is an included angle between the third paddle 23, the second paddle 24 and the first paddle 22, when the second synchronous pulley 31, the double-groove synchronous pulley 21 and the first synchronous pulley 25 rotate synchronously, they can sequentially drive the ventilation mesh plate 609 to flip.

[0037] The working principle of this utility model is as follows: During operation, the seeds to be dried are fed into the feed inlet 9, and then the C-type bucket elevator 1 transports the seeds to the seed dispensing inlet 11. Simultaneously, the drive motor 13 drives the second pulley 29 to rotate. The rotation of the second pulley 29 drives the drive shaft 17 to rotate, which in turn drives the bevel gear 28 to rotate. The rotation of the bevel gear 28 drives the turntable 16 to rotate, which in turn drives the connecting rod 10 to move. The movement of the connecting rod 10 drives the seed dispensing inlet 11. 4. The seed dispersing port 14 moves back and forth, evenly distributing the seeds entering the drying chamber 2. The diamond-shaped dispersing rods 7 disperse the seeds as they fall. Simultaneously, the hot air blower 3 starts, sending air into the ventilation pipe 4. The hot air enters the air inlet hood 30 through the ventilation pipe 4, and then enters the drying chamber 2 through the air inlet holes to dry the seeds. At the same time, the ventilation mesh plate 609 can be laid flat in a horizontal state to block the seeds. While the drive shaft 17 rotates, it can also drive the first transmission belt 26 and the second transmission belt 27. A first pulley 12 rotates, driving a second synchronous pulley 31, which in turn drives a synchronous belt 20. The synchronous belt 20 drives a double-grooved synchronous pulley 21, which in turn drives a first synchronous pulley 25. When the second synchronous pulley 31, the double-grooved synchronous pulley 21, and the first synchronous pulley 25 rotate, they respectively drive a third shifter 23, a second shifter 24, and a first shifter 22. These shifters, in turn, drive the intermediate shifter 606 to move. The movement of the paddle 606 can drive the rack 603, which in turn drives the gear 602 to rotate. The rotation of the gear 602 can cause the ventilation screen 609 to flip over, flipping the seeds down. After the third paddle 23 disengages from the middle paddle 606, the rack 603 is reset by the return spring 604, which restores the ventilation screen 609 to a horizontal state. The seeds that fall from the drying box 2 return to the C-type bucket elevator 1 through the discharge pipe 19 for circulation. When the seeds are dried, they are discharged from the discharge port 8 on the C-type bucket elevator 1.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
