[0019] Multiple row drying box 1 is connected by the lapping of interface 101 and interface plate 102, and the wet grain transported from grain inlet 2 is transported to grain outlet 3, and the drying process in multiple row drying box 1 is convenient for storage and shelling or crushing operation.

[0020] The end of air supply passage 5 extends into row drying box 1, and constant temperature chamber 9 is arranged vertically above the air supply passage 5 transport channel, the top surface and the bottom surface of constant temperature chamber 9 are uniformly provided with holes, baffle 10 is arranged vertically above constant temperature chamber 9, baffle 10 is V-shaped, and baffle 10 is fixedly installed in row drying box 1.

[0021] After the heating wire in constant temperature chamber 9 is electrified and heated, the energy transported by the air blower in heating bin 6 is used to transport heat energy to row drying box 1, and the wet grain in row drying box 1 is dried.

[0022] Inside the row drying oven 1, a rotating mechanism 11 is installed at a height corresponding to the connection ports 101 on both sides. The two ends of the rotating mechanism 11 are rotatably connected to a fan blade 12 and a striking ball 13. The height of the striking ball 13 is just enough to contact the frame of the screen 8. The frame of the screen 8 is solid, and the inside is a metal mesh. The screen 8 is inclined, and the inclination direction of the screen 8 is adapted to the setting height of the connection ports 101 on both sides. Multiple rotating mechanisms 11 are provided in the row drying oven 1.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual appendix Figures 1-3 When using this utility model, first arrange and install multiple drying boxes 1 in a row, then connect the corresponding connecting ports 101 and connecting plates 102. The connecting ports 101 and connecting plates 102 are distributed diagonally, so that the grain forms a downward inclined conveying channel.

[0026] Turn on the blower in the heating chamber 6 and the heating wire in the constant temperature chamber 9 to start heating the row drying box 1, so that the multiple row drying boxes 1 are kept at a constant temperature. When the wet grain is conveyed from the grain inlet 2 into the row drying box 1, it can dry its moisture and dehull better.

[0027] Refer to the instruction manual appendix Figures 3-5 Hot air is conveyed upward through the holes in the constant temperature chamber 9 and the V-shaped baffle 10, which simultaneously drives the rotation of the fan blades 12 and the grain on the screen 8 to be dried. The rotation of the fan blades 12 drives the rotation mechanism 11 to rotate, which can heat the grain more evenly (the falling grain will be evenly rotated and dried by the rotating mechanism 11 before falling onto the screen 8). While the fan blades 12 are rotating, the striking ball 13 is continuously struck against the edge of the screen 8 to prevent the grain from sticking to the edge and affecting the downward conveying.
