[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 5 The placing assembly 3 includes a placing plate 31, a connecting rod 32 fixedly connected to one side of the placing plate 31, a motor 33 fixedly connected to the outside of the drying box 1, and a rotating rod 34 fixedly connected to the output end of the motor 33. The placing plate 31 is fixedly connected to the rotating rod 34 on the side away from the connecting rod 32. The inner wall of the drying box 1 is provided with a mounting groove 12. The connecting rod 32 is rotatably connected to the mounting groove 12. The upper surface of the placing plate 31 is provided with a first air vent 311. The rotating rod 34 passes through the drying box 1. The placing assembly 3 is provided with two groups. The two groups of placing assemblies 3 are sequentially arranged inside the drying box 1 from top to bottom. When drying, the rice is placed on the top of the two groups of placing plates 31. The heating tube 5 In order to heat the air quickly, the hot air flow heats the rice on the top of the two groups of placement plates 31 through the second air vents 82 and the first air vents 311, and the rotating rod 34 is driven to rotate by the motor 33, thereby driving the placement plates 31 to rotate, and first the placement plates 31 at a lower height are flipped over. At this time, the placement plates 31 at a lower height are flipped over to pour the rice into the top of the pulling plate 8, and the placement plates 31 at a higher height are flipped over to pour the rice into the top of the placement plates 31 at a lower height. The flipping of the two groups of placement plates 31 helps to flip the rice during the drying process, effectively reducing the problems of agglomeration and incomplete drying of the rice, making the heat distribution more even, and facilitating shortening the drying time and accelerating the drying cycle.

[0027] A first slide groove 13 is provided on the inner wall of the drying box 1, and a slider 81 is fixedly connected to the outer surface of the pull-out plate 8. The slider 81 is slidably connected to the first slide groove 13. When the pull-out plate 8 is pulled, the slider 81 slides along the first slide groove 13, which facilitates the pull-out plate 8 to be taken out from the inside of the drying box 1 to collect the dried rice.

[0028] The outer surface of the drying box 1 is provided with a circulation component 4 for circulating hot air flow, and the circulation component 4 includes a drying box 43 fixedly installed on the top of the drying box 1, an air pump 41 fixedly installed on one side of the drying box 43, an air intake pipe 42 fixedly installed on the air intake end of the air pump 41, a connecting pipe 44 fixedly connected to one side of the drying box 43, an air supply pipe 45 fixedly connected to the outer surface of the connecting pipe 44, and a drying box 46 arranged inside the drying box 43, a third air vent 461 is opened on the lower surface of the drying box 46, drying cotton is placed inside the drying box 46, the air supply pipe 45 is arranged above the drying box 46, and the air intake pipe 42 runs through the drying box 1. Under the action of the air pump 41, the moist airflow after drying the rice in the drying box 43 enters the drying box 43 through the air intake pipe 42, absorbs moisture in the moist airflow under the action of the drying cotton, and the airflow after being dried by the drying cotton flows through the connecting pipe 44, and is finally discharged through the air supply pipe 45, thereby realizing the recycling of airflow.

[0029] An air inlet 11 is provided on the side wall of the drying box 1, and an air supply pipe 45 is arranged inside the air inlet 11. There are multiple groups of air inlets 11 and air supply pipes 45. By setting up multiple groups of air inlets 11 and air supply pipes 45, it is convenient for hot air flow to enter the drying box 1 evenly from multiple directions, so that the hot air flow distribution is more even. The air supply pipe 45 is arranged inside the air inlet 11 without passing through the air inlet 11 to prevent interference with the flipping of the placement plate 31.

[0030] A second slide groove 431 is provided on one side of the drying box 43, and the drying box 46 is slidably connected to the second slide groove 431. When the drying box 46 is pulled, the drying box 46 slides along the second slide groove 431, so that the drying box 46 can be taken out to replace the saturated drying cotton.

[0031] A pressure relief pipe 6 is fixedly connected to the top of the drying box 1, and a pressure relief valve 61 is fixedly connected to the outer surface of the pressure relief pipe 6. During the drying process, as the temperature rises, a certain positive pressure will be generated inside the drying box 1. The cooperation between the pressure relief valve 61 and the pressure relief pipe 6 facilitates the timely release of this excess pressure to ensure the safety of the drying operation.

[0032] When in use, the rice is placed on the top of the two groups of placement plates 31. After placement, the box door 2 is closed. The heating tube 5 is convenient for quickly heating the air. The hot air flow passes through the second air vent 82 and the first air vent 311 to heat the rice on the top of the two groups of placement plates 31. Under the action of the air pump 41, the moist air flow after the rice is dried in the drying box 43 enters the drying box 43 through the suction pipe 42, absorbs the moisture in the moist air flow under the action of the drying cotton, and the air flow after being dried by the drying cotton flows through the connecting pipe 44, and is finally discharged through the multiple groups of air supply pipes 45, so that the hot air flow enters the drying box 1 evenly from multiple directions, so that the hot air flow distribution is more even, and the motor 33 drives the rotating rod 34 to rotate. Thereby, the placement plate 31 is driven to rotate, and the placement plate 31 at a lower height is flipped first. At this time, the placement plate 31 at a lower height is flipped to pour the rice into the top of the pull-out plate 8, and the placement plate 31 at a higher height is flipped to pour the rice into the top of the placement plate 31 at a lower height. The flipping of the two groups of placement plates 31 helps to flip the rice during the drying process. After the heating is completed, the box door 2 is opened and the pull-out plate 8 is pulled. At this time, the slider 81 slides along the first slide groove 13, which is convenient for taking out the pull-out plate 8 from the inside of the drying box 1 to collect the dried rice. The drying box 46 is pulled, and the drying box 46 slides along the second slide groove 431, which is convenient for taking out the drying box 46 to replace the saturated drying cotton.
