[0002] Grain processing refers to the business activities of transforming raw grains into semi-finished grains or finished grains, or vice versa. During grain processing, drying is necessary to extend the storage time of grains and effectively prevent them from being damaged by insects.
[0003] Traditional grain drying equipment places the grain in a drying chamber for drying, lacking an effective stirring and stratified drying mechanism. As a result, the grain takes a long time to dry, which reduces production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a drying device for grain processing in order to solve the problems of lack of effective stirring and layer drying mechanisms.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a box body, a drying trough on the side of the box body, a movable plate on the side of the drying trough, two hinges between one side of the movable plate and the box body, and two latches between the movable plate and the box body on the side away from the hinges. A first ventilation plate of matching size is movably connected to the upper end of the drying trough. A second ventilation plate of the same size is movably connected below the first ventilation plate, and a third ventilation plate of the same size is movably connected below the second ventilation plate. Two stirring devices are symmetrically arranged above the first, second, and third ventilation plates. Two electric telescopic rods are symmetrically fixed on both sides below the first, second, and third ventilation plates. A ventilation plate is located on the side of the drying trough away from the movable plate. A discharge port is located at both ends of the box body, and a conveyor belt is movably connected to the side of each discharge port. A hot air blower is located on the side of the box body away from the movable plate. A controller is located at one end of the box body.
[0006] Furthermore, the stirring device includes a drive motor, a rotating shaft is provided above the drive motor, four extension shafts are surrounded on the side of the rotating shaft, and several movable plates are arranged on the upper and lower sides of the extension shafts.
[0007] Furthermore, the drive motor is fixed below the three ventilation plates, and the extension shaft is movably connected to the movable plate above the three ventilation plates.
[0008] Furthermore, the movable plate has the same length and height as the box body and the two are movably connected.
[0009] Furthermore, the electric telescopic rod below the first ventilation plate is fixed to the upper surface of the second ventilation plate, the electric telescopic rod below the second ventilation plate is fixed to the upper surface of the third ventilation plate, and the electric telescopic rod below the third ventilation plate is fixed to the bottom of the drying tank.
[0010] Furthermore, the surface of the ventilation plate has ventilation holes that match the size of the hot air blower, and the surfaces of the first ventilation plate, the second ventilation plate, and the third ventilation plate have ventilation holes.
[0011] Furthermore, one end of the conveyor belt is movably connected to the inside of the discharge port, and both the second ventilation plate and the third ventilation plate are movably connected to the inside of the drying tank.
[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:
[0013] By setting up a first, second, and third ventilation plate, the grain can be placed and dried in layers. The electric telescopic rods under each ventilation plate can lift the plate to the appropriate position in sequence. In conjunction with the hot air blower and stirring device, the ventilation holes allow air to pass through both the top and bottom sides of the grain during the drying process, which speeds up the drying process, improves the drying efficiency, ensures uniform heating of the grain, and guarantees the drying quality. The stirring device can spread the grain evenly on the ventilation plate, and the cooperation between the conveyor belt and the feeding port can precisely control the amount of grain transported to each ventilation plate, avoiding too much or too little grain. This achieves precise handling of different amounts of grain and avoids affecting the drying quality of the grain. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Combination Figures 1 to 4 The grain drying device shown includes a housing 1, a drying trough 10 on one side of the housing 1, a movable plate 2 on the side of the drying trough 10, two hinges 3 between one side of the movable plate 2 and the housing 1, and two latches 4 between the movable plate 2 away from the hinges 3 and the housing 1. A first ventilation plate 5 of the same size is movably connected to the upper part of the interior of the drying trough 10, a second ventilation plate 6 of the same size is movably connected below the first ventilation plate 5, and a third ventilation plate 7 of the same size is movably connected below the second ventilation plate 6. Two symmetrical ventilation plates are arranged above the first ventilation plate 5, the second ventilation plate 6, and the third ventilation plate 7. The mixing device 8 has two electric telescopic rods 9 symmetrically fixed on both sides below the first ventilation plate 5, the second ventilation plate 6, and the third ventilation plate 7. The drying tank 10 has a ventilation plate 11 on the side away from the movable plate 2. Both ends of the box body 1 have a discharge port 12, and the sides of the discharge port 12 are movably connected to a conveyor belt 13. The conveyor belt is fixed and supported at the bottom of the conveyor belt 13 by a support leg with a limit pulley. A hot air blower 14 is provided on the side of the box body 1 away from the movable plate 2, and a controller 15 is provided at one end of the box body 1. The control connection method between the motor, the electric telescopic rod, the hot air blower, and the controller in this utility model is the prior art and will not be described in detail.
[0022] The stirring device 8 includes a drive motor 81, a rotating shaft 82 above the drive motor 81, four extension shafts 83 surrounding the side of the rotating shaft 82, and several movable plates 84 arranged on the upper and lower sides of the extension shafts 83. The motor, electric telescopic rod, hot air blower, buckle, hinge and conveyor belt in this utility model are existing technologies and will not be described in detail.
[0023] The drive motor 81 is fixed below the three ventilation plates, and the extension shaft 83 is movably connected to the moving plate above the three ventilation plates; the length of the extension shaft 83 can rotate inside the drying tank.
[0024] The movable plate 2 has the same length and height as the box 1 and the two are movably connected.
[0025] The electric telescopic rod 9 below the first ventilation plate 5 is fixed to the upper surface of the second ventilation plate 6, the electric telescopic rod 9 below the second ventilation plate 6 is fixed to the upper surface of the third ventilation plate 7, and the electric telescopic rod 9 below the third ventilation plate 7 is fixed to the bottom of the drying tank 10.
[0026] Ventilation plate 11 has ventilation holes through its surface and is the same size as hot air blower 14. Ventilation plates 5, 6 and 7 have ventilation holes through their surfaces. When drying is performed, each ventilation plate is located on the side of hot air blower 14. The size of the ventilation opening is smaller than that of traditional grains.
[0027] One end of the conveyor belt 13 is movably connected to the inside of the discharge port 12. The second ventilation plate 6 and the third ventilation plate 7 are both movably connected to the inside of the drying trough 10. After conveying the grain, the conveyor belt 13 is moved away by the support legs with pulleys at the bottom. The discharge port 12 can discharge moisture during drying.
[0028] Working Principle: In operation, the grain is first conveyed via conveyor belt 13 and discharge port 12 to the top of the first ventilation plate 5. Then, the stirring device 8 is activated, and the drive motor 81, in conjunction with the rotating shaft 82, drives the extension shaft and moving plate 84 to rotate, spreading the grain evenly on the first ventilation plate 5. After a suitable amount is conveyed, the conveyor belt 13 stops. Then, the electric telescopic rod 9 on the second ventilation plate lifts the first ventilation plate 5 to the top of the drying trough. The conveyor belt 13 then resumes conveying the grain. This process is repeated until the second ventilation plate 6, after being filled with a suitable amount of grain, is lifted by the electric telescopic rod 9 on the third ventilation plate 7. Raise the feed inlet 12 above the top, and then follow the steps described above to place an appropriate amount of grain on the third ventilation plate 7. Then, use the electric telescopic rod 9 at the bottom of the drying trough to raise the third ventilation plate 7 to the bottom of the hot air blower, so that the grain on the third ventilation plate is below the feed inlet. This prevents the grain from leaking out of the feed inlet during the drying and stirring process. Then, start the hot air blower and the stirring device to stir and dry the grain. This layered stirring and drying of the grain, combined with the ventilation holes on the ventilation plate to allow air to pass through from both the top and bottom sides of the grain, can accelerate the drying speed. After drying, the movable plate can be opened by locking to remove the grain for collection and storage.
