[0025] like Figure 1 As shown, a dehumidification box 131 is also included. The dehumidification box 131 is installed at the connection between the air blower 13 and the diversion component 14, which can make the heated air dry before entering.
[0026] like Figure 2 As shown, the diverter assembly 14 includes a diverter pipe 141, an annular pipe 142 and a filter screen 143. The annular pipe 142 is evenly fixed on the outer ring of the drying cylinder 1, and a raised circular pipe is inserted into the outer wall of the drying cylinder 1. The diverter pipes 141 are welded on the left and right ends of the annular pipe 142, and the diverter pipes 141 are respectively connected to the air supply fan 13 and the exhaust fan 15. A filter screen 143 is fixed on the annular pipe 142, which is located at the end of the circular pipe where the annular pipe 142 is inserted into the drying cylinder 1.
[0027] like Figure 3 , Figure 6 and Figure 7As shown, it also includes a baffle frame 3, a round-headed rod 31, a handle 32, a fixing block 33, a limiting U-rod 34 and an elastic member 35. The baffle frame 3 is slidably connected to the lower end of the four-way conduit 2, and a sliding groove is opened at the front end of the vertical part of the four-way conduit 2. A handle 32 is welded in the middle of the top of the baffle frame 3, round-headed rods 31 are welded on both sides of the top of the baffle frame 3, and fixing blocks 33 are welded on the left and right sides of the baffle frame 3.

In the process of the baffle frame 3 moving upward and contacting the limiting U-rod 34, the handle 32 will not exceed the height of the sliding groove opened at the front end of the vertical part of the four-way conduit 2.
[0028] The staff turns on the motor Ⅰ17, the blower 13 and the motor Ⅱ23, and pours the grain to be dried into the opening at the rear end of the four-way guide tube 2. The motor Ⅱ23 drives the feeding belt 22 to rotate, and then drives the grain to move upward and pour it into the drying cylinder 1 through the feeding hopper 16. At this time, the motor Ⅰ17 drives the push plate 19 to rotate clockwise, and the grain just unloaded passes through the gap of the first segmented partition 18. In the process of moving, the dry hot air takes away the moisture in the grain. When it moves to the gap of the segmented partition 18, the grain falls, and each time it falls from the upper layer to the lower layer of the segmented partition 18, the edge of the grain falls to the middle position of the lower layer through the guide plate 181, and each time it rotates one circle before falling. By changing the speed of the motor Ⅰ17, the drying time can be fully adjusted. After the plate 18 is passed, the dried grain is collected from the opening at the bottom of the four-way conduit 2. During the drying process, the exhaust fan 15 is turned on intermittently so that the supplied air can fully contact the grain, and under the diversion of the diverter pipe 141 and the annular pipe 142, the gas can effectively absorb the moisture of the grain, and the filter 143 can prevent the grain from entering the annular pipe 142. If it is found that the drying effect of the grain still does not meet the specified standard, the limit U rod 34 is pulled backward to compress the elastic member 35. After the baffle frame 3 falls, the limit U rod 34 is released, and the elastic member 35 rebounds to block the opening at the bottom of the four-way conduit 2. The grain will continue to flow downward along the baffle frame 3 and be repeatedly loaded through the bucket of the loading belt 22. After passing the test, the handle 32 is pulled to raise the baffle frame 3, and the round head rod 31 squeezes the limit U rod 34 and limits it.
[0029] like Figure 4 and Figure 5 As shown, it also includes a limit plate 4 and a stirring frame 41. Between every two push plates 19, a limit plate 4 is welded on the upper and lower sides, and the stirring frame 41 is rotatably connected between the limit plates 4.
[0030] like Figure 4 and Figure 5 As shown, it also includes a fixed wheel 5 and a rotating wheel 51. The fixed wheel 5 is welded to the top of the drying cylinder 1 and the bottom of the segmented partition 18, and the rotating wheel 51 is welded to the bottom of the stirring frame 41. The rotating wheel 51 is meshed with the fixed wheel 5.
[0031] In the process of pushing the grain, the stirring frame 41 rotates along with the push plate 19, and the rotating wheel 51 is meshed with the fixed wheel 5, so that the push plate 19 rotates to stir the grain and optimize the contact effect between the grain and the air.
[0032] like Figure 1 and Figure 8 As shown, a sampling window 6 is also included. The sampling window 6 is arranged at the lower end of the four-way conduit 2.
[0033] Through the sampling window 6, no grain will fall when sampling, so it is convenient to take out the material and check the drying condition of the grain.
[0034] The specific steps of the segmented drying method are as follows: S1, turn on the motor I 17, the blower 13 and the exhaust fan 15, and pour the grain to be dried into the drying cylinder 1 through the feed hopper 16; S2, the motor I 17 drives the push plate 19 to rotate, and the push plate 19 is stirred by the stirring frame 41 during the movement, and the dry hot air takes away the moisture in the grain, and the grain falls down in sections; S3, when falling from the upper layer to the next layer of segmented partition 18, the grain on the edge falls to the middle position of the next layer through the guide plate 181; S4, after passing through all segmented partitions 18, the dried grain is collected from the bottom.
[0035] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
