[0002] Rice refers to the seeds without removing the husk. Botanically, it belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Oryza in the Gramineae family. The moisture content of the rice just after threshing is high. If it is not dried in time, it is easy to germinate and mold, affecting the quality and storage of the rice. By drying, the moisture content of the rice can be effectively reduced, thereby avoiding the problems of germination and mold in the rice, ensuring the safe storage of the rice. Secondly, drying the rice helps to improve its quality and taste; therefore, we need a circulating rice drying device;

[0026] When in use, the rice is located outside the air inlet pipe 2, the filter 7 is located inside the air inlet pipe 2, and the outer wall of the filter 7 is in contact with the inner wall of the air inlet pipe 2. When the rice moves, the filter 7 isolates the ventilation holes 3 to prevent the rice from entering the air inlet pipe 2 along the ventilation holes 3 when moving, thereby preventing the rice from accumulating inside the air inlet pipe 2, thereby avoiding a reduction in drying efficiency, and preventing the parts inside the air inlet pipe 2 from being damaged by the rice.

[0027] Reference Figure 4 The inner side wall of the drying device housing 1 is fixedly connected with a partition 10, and the partition 10 divides the interior of the drying device housing 1 into two parts. The bottom of the drying device housing 1 is fixedly connected with a motor 12, and the motor 12 is connected to an external power supply. The output end of the motor 12 is fixedly connected with an auger body 13, and the auger body 13 is located inside the drying device housing 1, and the auger body 13 is connected to the motor 12 in a rotational connection with the drying device housing 1. The inner bottom of the drying device housing 1 is fixedly connected with a vertical bucket 11, and the vertical bucket 11 is located inside the drying device housing 1. The vertical bucket 11 is The drying device is bucket-shaped, and the bottom of the auger body 13 is located inside the vertical bucket 11. The inner bottom wall of the drying device shell 1 is fixedly connected with the auger shell 25. The auger shell 25 is located inside the vertical bucket 11. The auger body 13 is located inside the auger shell 25. The top outer wall of the auger shell 25 is connected with the discharge chute 15. When in use, the motor 12 is started, and the motor 12 drives the auger body 13 to rotate. At this time, the rice is poured into the vertical bucket 11. When the auger body 13 rotates, it drives the rice to climb inside the auger shell 25, thereby displacing the rice.

[0028] Reference Figure 1 and Figure 2The outer wall of the drying device casing 1 is fixedly connected with an escalator 23, and the escalator 23 is set with an inclination angle. When the staff needs to replace the filter 7, they can climb to the top of the drying device casing 1 through the escalator 23 to further replace the filter 7, thereby improving the safety of the staff and the maintenance efficiency.

[0029] Reference Figure 3 The inner wall of the drying device shell 1 is fixedly connected with a fixing frame 14, and three fixing frames 14 are arranged. The three fixing frames 14 are distributed in a linear array along the direction of the auger shell 25, and the inner wall of the fixing frame 14 is fixedly connected to the outer wall of the auger shell 25. The three fixing frames 14 limit the angle of the auger shell 25 to prevent the angle of the auger shell 25 from changing during use, thereby preventing the auger shell 25 from tipping over during use.

[0030] Reference Figure 3 A closing plate 16 is fixedly connected to the top of the drying device shell 1, and a feed hopper 17 is connected to the top of the closing plate 16. The side of the feed hopper 17 away from the discharge trough 15 is provided with an inclination angle, and the inner wall of the feed hopper 17 is fixedly connected to the outer wall of the discharge trough 15. When the auger body 13 lifts the rice, the rice is lifted to the discharge trough 15, discharged from the discharge trough 15, and hits the inner wall of the feed hopper 17. Since the side of the feed hopper 17 away from the discharge trough 15 is provided with an inclination angle, when the rice hits the inner wall of the feed hopper 17, it will enter the interior of the drying device shell 1 along the inner wall of the feed hopper 17. At this time, the rice is located on the side of the partition 10 away from the auger shell 25, and the staff can put the rice through the feed hopper 17.

[0031] Reference Figure 2 and Figure 4 The inner side wall of the drying device housing 1 is fixedly connected with an inclined plate 18, and a plurality of inclined plates 18 are provided. The plurality of inclined plates 18 are evenly distributed on the inner side wall of the drying device housing 1, and the plurality of inclined plates 18 are all located on the side of the partition 10 away from the auger housing 25. The inclined plates 18 are provided with an inclined angle. When the staff puts the rice into the drying device housing 1 through the feed hopper 17, the rice first contacts the top of the uppermost inclined plate 18. Since the inclined plate 18 is provided with an inclined angle, when the rice contacts the top of the inclined plate 18, it will move along the inclined plate 18. It falls at an inclined angle and repeatedly contacts the inclined plates 18 at various heights, and finally falls to the bottom of the drying device casing 1, delaying the time that the rice stays inside the drying device casing 1, increasing the drying time, and thus improving the drying efficiency. An opening is provided at the bottom of the drying device casing 1, and the opening connects the cavities on both sides of the partition 10. When the rice falls to the bottom of the drying device casing 1, it enters the interior of the vertical bucket 11 through the opening, and is further lifted by the auger body 13, and then the rice is repeatedly dried.

[0032] Reference Figure 4 and Figure 5 A base 19 is fixedly connected to the bottom of the drying device casing 1, and the inner bottom wall of the base 19 is fixedly connected to the bottom of the motor 12. An air inlet 20 is fixedly connected to the bottom of the drying device casing 1, and a heating wire 21 is provided on the inner side wall of the air inlet 20. The heating wire 21 is connected to an external power supply. A fan 22 is fixedly connected to the bottom of the air inlet 20, and the fan 22 is connected to an external power supply. When in use, the fan 22 is started, and the fan 22 draws external air. The heating wire 21 is started. When the air flows through the heating wire 21, the heating wire 21 heats the air, thereby drying the rice inside the drying device casing 1.

[0033] Reference Figure 1 The outer wall of the drying device shell 1 is provided with an observation port 24, and there are four observation ports 24. The four observation ports 24 are distributed in a linear array on the outer wall of the drying device shell 1. When it is necessary to observe or clean the inside of the drying device shell 1, the staff can climb to a specified height via the escalator 23, and after opening the observation port 24, observe or clean the inside of the drying device shell 1, thereby improving the staff's control over the drying effect inside the drying device shell 1. At the same time, when it is necessary to clean the inside of the drying device shell 1, the staff can climb to the designated observation port 24 via the escalator 23, and after opening one of the observation ports 24, clean the inside of the drying device shell 1, thereby improving the maintenance efficiency of the equipment and preventing the staff from entering the inside of the drying device shell 1, thereby reducing the personal risk of the staff.

[0034] Working principle: When in use, the rice is located outside the air inlet pipe 2, the filter 7 is located inside the air inlet pipe 2, and the outer wall of the filter 7 is in contact with the inner wall of the air inlet pipe 2. When the rice moves, the filter 7 isolates the ventilation holes 3 to prevent the rice from entering the air inlet pipe 2 along the ventilation holes 3 when moving, thereby preventing the rice from accumulating inside the air inlet pipe 2, thereby preventing the drying efficiency from being reduced, and preventing the parts inside the air inlet pipe 2 from being damaged by the rice.

[0035] After the filter 7 is installed, the fan 22 is started to extract the external air, and the heating wire 21 is started. When the air flows through the heating wire 21, the heating wire 21 heats the air. Under the action of the fan 22, the hot air moves toward the top of the drying device shell 1 along the direction of the air inlet pipe 2. During the movement, it flows to the inside of the drying device shell 1 along the multiple ventilation holes 3, thereby drying the rice inside the drying device shell 1. The staff pours the rice into the drying device shell 1 along the feed hopper 17. At this time, the rice first contacts the top of the uppermost inclined plate 18. Since the inclined plate 18 is set at an inclined angle, the rice When it touches the top of the inclined plate 18, it will fall along the inclined angle, and then repeatedly touch the inclined plates 18 at various heights, and finally fall to the bottom of the drying device shell 1, delaying the time that the rice stays inside the drying device shell 1. An opening is provided at the bottom of the drying device shell 1, and the opening connects the cavities on both sides of the partition 10. When the rice falls to the bottom of the drying device shell 1, it enters the interior of the vertical bucket 11 through the opening, and is further lifted by the auger body 13. When the rice is further lifted to the discharge trough 15, the rice is discharged along the discharge trough 15, and then enters the interior of the drying device shell 1 along the feed hopper 17, and then the rice is repeatedly dried.
