[0003] Traditional rice seeds are generally dried in the sun and then stored for use in the coming year or sold directly. However, since they are dried outdoors, the proportion of water vapor dried on the surface of the rice seeds is not high, and they are prone to deterioration during storage. At the same time, the rice seeds are easily mixed with some straws, shriveled rice husks, and dust, resulting in low quality of the rice seeds and low selling prices. Summary of the Invention

[0004] In order to overcome the problems that the drying effect of traditional rice seeds dried by the sun is poor, they are prone to deterioration during storage, and the rice seeds are easily mixed with some straws, shriveled rice husks, and dust, the utility model provides a dust-removing and drying integrated rice seed dryer. The rice seeds to be dried fall onto the conveying mechanism through the feeding hopper. The blower removes the straws, shriveled rice husks, and dust on the rice seeds. The rice seeds after removing impurities fall into the drying cylinder. The driving mechanism drives the drying cylinder to rotate at a constant speed. The electric heating tube heats and dries the rice seeds inside the drying cylinder, so as to ensure the drying effect of the device on the rice seeds.

[0020] Before the drying and dust removal operation, the staff places the rice seeds in the lower hopper 4. After placement, the fan 6, the motor 34, the drive motor 93, and the electric heating tube 12 are turned on in sequence. During drying, the staff holds the handle 411 to pull the pull-out plate 41 out of the lower hopper 4, and the rice seeds in the lower hopper 4 fall onto the conveyor belt 33. The motor 34 drives the active roller 31 and the driven roller 32 to rotate, thereby realizing the conveyor belt 33 to convey the rice seeds. The fan 6 removes the straw, shriveled rice husks, and dust on the rice seeds. The partition plate 5 divides the conveyor belt 33 into two parts. The straw, shriveled rice husks, and dust are transported to the collecting box 14 through the conveyor belt 33 and the lower feeding tray 7. The rice seeds after impurities are removed are then conveyed to the collecting box 14 through the conveyor belt 33 and the lower feeding tray 7. The material tray 7 and the receiving tray 11 cooperate to fall into the drying drum 10 for drying. The driving motor 93, the connecting shaft 94, and the reducer 95 cooperate to drive the rotating shaft 91 to rotate.

After the drying is completed, the staff turns off the fan 6, the motor 34, the driving motor 93, and the electric heating tube 12, and the drying drum 10 stops rotating. The staff opens the cover 13 at the end of the drying drum 100 and takes out the rice seeds after drying.

[0021] If Figure 4 、 Figure 5 As shown in the figure, the conveying mechanism 3 includes an active roller 31, a driven roller 32, a conveyor belt 33, a motor 34, and a baffle 35. The active roller 31 and the driven roller 32 are rotatably mounted on the support frame 2 through a bearing seat. The conveyor belt 33 is wound around the active roller 31 and the driven roller 32. The motor 34 is mounted on the top of the frame 1. The active roller 31 is connected to the output end of the motor 34 by transmission. The baffle 35 is mounted on the supporting beam 21 of the support frame 2. The baffle 35 is located on both sides of the conveyor belt 33. The fan 6 is mounted on the baffle 35. The bottom end of the unloading tray 7 is equipped with a collecting box 14. When the rice needs to be irrigated, the collecting box 14 is installed on the bottom end of the unloading tray 7. When the seeds are being dusted and dried, the motor 34 is turned on, and the motor 34 drives the active roller 31 and the driven roller 32 to rotate, thereby realizing the conveying of the rice seeds by the conveyor belt 33. The fan 6 removes the straw, shriveled rice husks and dust on the rice seeds. The partition plate 5 divides the conveyor belt 33 into two parts. The straw, shriveled rice husks and dust are transported to the collection box 14 through the conveyor belt 33 and the feed tray 7. The rice seeds after the impurities are removed fall into the drying cylinder 10 through the cooperation of the conveyor belt 33, the feed tray 7 and the receiving tray 11 for drying. The baffle 35 prevents the rice seeds from falling from both sides of the conveyor belt.

[0022] If Figure 3 ​As shown in the figure, a pull-out tray 41 is provided at the bottom end of the blanking hopper 4, and a handle 411 is provided on the pull-out tray 41. Before the drying and dust removal operation, the staff places the rice seeds inside the blanking hopper 4. During drying, the staff holds the handle 411 and pulls out the pull-out tray 41 from the blanking hopper 4, and the rice seeds in the blanking hopper 4 fall onto the conveyor belt 33. The conveyor belt 33 conveys the rice seeds with impurities removed to the inside of the drying cylinder 10 for drying treatment.

[0023] As Figure 2 shown, the driving mechanism 9 includes a rotating shaft 91, a guide wheel 92, a driving motor 93, a connecting shaft 94, and a speed reducer 95.

Two sets of speed reducers 95 are installed at both ends of the driving motor 93. One end of the connecting shaft 94 is connected to the driving motor 93, and the other end is connected to the input end of the speed reducer 95. The rotating shaft 91 is connected to the output end of the speed reducer 95. When drying, the driving motor 93 and the electric heating tube 12 are turned on. The cooperation of the driving motor 93, the connecting shaft 94, and the speed reducer 95 drives the rotating shaft 91 to rotate. The rotation of the rotating shaft 91 drives the guide wheel 91 to rotate, thereby realizing the rotation of the drying cylinder 10, causing the rice seeds inside the drying cylinder 10 to continuously tumble. The electric heating tube 12 heats and dries the rice seeds inside the drying cylinder 10, enabling the rice seeds to be evenly heated, so as to ensure the drying effect of the device on the rice seeds.

[0024] Working process:

[0025] Before the drying and dust removal operation, the staff place the rice seeds inside the feeding hopper 4. After the placement, the fan 6, the motor 34, the driving motor 93, and the electric heating tube 12 are turned on in sequence. During drying, the staff hold the handle 411 and pull out the pulling plate 41 from the feeding hopper 4. The rice seeds in the feeding hopper 4 fall onto the conveyor belt 33. The motor 34 drives the driving roller 31 and the driven roller 32 to rotate, thereby realizing the conveyance of the rice seeds by the conveyor belt 33. The fan 6 removes the straw, shriveled rice husks, and dust on the rice seeds. The partition plate 5 divides the conveyor belt 33 into two parts. The straw, shriveled rice husks, and dust are conveyed to the collection box 14 through the conveyor belt 33 and the feeding tray 7. The rice seeds after removing impurities fall into the drying cylinder 10 through the cooperation of the conveyor belt 33, the feeding tray 7, and the receiving tray 11 for drying treatment. The cooperation of the driving motor 93, the connecting shaft 94, and the reducer 95 drives the rotating shaft 91 to rotate. The rotation of the rotating shaft 91 drives the guide wheel 91 to rotate, thereby realizing the rotation of the drying cylinder 10, making the rice seeds inside the drying cylinder 10 continuously tumble. The electric heating tube 12 heats and dries the rice seeds inside the drying cylinder 10, enabling the rice seeds to be evenly heated, so as to ensure the drying effect of the device on the rice seeds. After drying, the staff turn off the fan 6, the motor 34, the driving motor 93, and the electric heating tube 12. The drying cylinder 10 stops rotating. The staff open the cover 13 at the end of the drying cylinder 100 and take out the dried rice seeds. This device integrates the functions of drying and impurity removal, ensuring that the seeds are fully dried and enabling the seeds to be fully decontaminated, which is beneficial to the efficient drying and impurity removal of the seeds.
