[0026] The disintegrating parts are symmetrically arranged in the inner cavity of the drying box 11 at the position below the corresponding feeding port 13 .

[0027] When the grains to be dried are added from the feeding port 13, the grains generally fall into the drying box 11 in piles, and the grains falling into the drying box 11 are dried by the provided drying parts, and the fallen piles of grains are broken up by the breaking parts provided below the feeding port 13 to prevent the grains from falling in piles, thereby increasing the drying efficiency of the grains.

[0028] The disintegrating parts include a rotating shaft 21 and a partition 22. The two ends of the rotating shaft 21 are rotatably connected to the side walls on the front and rear sides of the drying box 11 respectively. A plurality of partitions 22 are arranged in an array and spaced apart on the surface of the rotating shaft 21. A driving member 1 is arranged on the outer wall of the rear side of the drying box 11 at a position corresponding to the rotating shaft 21. The output end of the driving member 1 is connected to the rotating shaft 21, and the driving member 1 drives the two rotating shafts 21 to rotate in a direction away from each other.

[0029] The driving member 1 is a motor, which drives the rotating shaft 1 21 and the partition 1 22 to rotate away from each other, thereby breaking up the falling grains.

[0030] A filter screen 23 is also provided in the inner cavity of the drying box 11 at a position below the scattered parts. The filter screen 23 is tiltedly provided on the inner side walls on both sides opposite to each other, and the ends of the two filter screens 23 close to each other are lower.

[0031] A second filter screen 24 is also provided at the bottom of the cavity inside the drying box 11. The second filter screen 24 is arched and does not completely fit the inner bottom wall.

[0032] The mesh diameters of the filter 1 23 and the filter 2 24 are both smaller than the diameter of the grains. The filter 1 23 can prolong the falling time of the grains. The grains are scattered by the scattering element and fall onto the inclined filter 1 23, and then slide down onto the filter 2 24. The grains are accumulated on the arched filter 2 24, which is convenient for the drying element arranged below to dry them, further improving the drying efficiency.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The figure shows the overall structure of the drying device in the embodiment. Figure 2 FIG. 1 is a schematic top view of the air guide tube in the embodiment. Figure 3 Shown is a schematic side view of a flap in an embodiment.

[0034] The drying box 11 further includes a flipping member 25, which is disposed between the filter screen 1 23 and the filter screen 24. A driving member 26 is disposed on the outer side wall of the drying box 11 at a position corresponding to the flipping member 25. The output end of the driving member 26 is connected to the flipping member 25, and the flipping member 25 flips the grains accumulated on the upper end of the filter screen 24.

[0035] The turning member 25 can turn over the grains accumulated on the second filter screen 24, so that the grains are dried evenly. The second driving member 26 is a motor, which plays a role in driving the turning member 25 to rotate.

[0036] The flip member 25 includes a second rotating shaft 27 and a flip plate 28. The two ends of the second rotating shaft 27 are rotatably arranged on the inner side walls of the drying box 11 on both sides. The flip plate 28 is symmetrically arranged on the outer surface of the second rotating shaft 27. The output end of the second driving member 26 is connected to the second rotating shaft 27.

[0037] The second driving member 26 drives the second rotating shaft 27 to rotate, thereby driving the turning plate 28 to continuously turn the piled grains, thereby improving the grain drying efficiency and making the grains dry evenly.

[0038] The drying component includes a fan 31 and an air guide tube 32. The fan 31 is arranged inside the mounting seat and is connected to a driving component fixed on the inner bottom wall of the mounting seat. The air guide tube 32 is arranged inside the mounting seat at a position directly above the fan 31, and the other end of the air guide tube 32 extends to the outside of the mounting seat.

A plurality of heating wires 34 arranged at intervals are provided in the air guide tube 32, and a plurality of air inlet holes 33 are opened through the bottom plate of the mounting seat.

[0039] The driving part 3 is a motor, which drives the fan 31 to rotate. The fan 31 inhales cold air from the air inlet 33 and blows it into the air guide tube 32. The cold air is heated by the heating wire 34 in the air guide tube 32, and the heated hot air is blown out from the dust cover above into the drying box 11. The grains inside the drying box 11 are dried. The dust cover can play a dustproof role to prevent dust from falling from the grains from entering the air guide tube 32 and affecting the operation of the fan 31.

[0040] Specifically, a plurality of exhaust holes are provided on the side wall of the drying box 11 to ensure air convection so that hot air can smoothly enter the drying box 11 and realize air exchange inside the drying box 11 .

[0041] Working principle: When using this device to dry grains, first turn on the drying part to pass hot air into the drying box 11, and at the same time add the grains to be dried from the feeding port 13. The grains are first broken up by the breaking parts to prevent the grains from falling in piles. After the breaking parts break up the grains, they fall onto the top of the inclined filter screen 1 23, and then slide down to the filter screen 2 24. The grains are finally accumulated on the arched filter screen 24. Finally, turn on the driving part 26 to drive the rotating shaft 27 to rotate, thereby driving the flip plate 28 to continuously flip the accumulated grains, thereby improving the grain drying efficiency and making the grains dry evenly.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
