The universal wheel 2 is installed at the bottom end of the drying box 1, and an oscillation mechanism and a drying mechanism are arranged inside and on the outer wall of the drying box 1.

[0027] The oscillating mechanism comprises a charging unit and a shaking unit.

[0028] The shaking unit includes a mounting plate 305, a driving motor 306, a connecting piece 307, a supporting seat 308, a connecting column 309 and a clamping column 310. The mounting plate 305 is mounted on the side of the drying box 1, the driving motor 306 is mounted on one side of the mounting plate 305, the connecting piece 307 is mounted on the rotating end of the driving motor 306, the bottom end of the connecting piece 307 is engaged with multiple groups of clamping columns 310, and the connecting column 309 is continuously moved laterally through the back and forth swinging of the connecting piece 307 and the connection of multiple groups of clamping columns 310, thereby driving the loading box 302 to move laterally continuously, the supporting seat 308 is mounted on the side of the drying box 1, and the connecting column 309 is movably mounted on one side of the loading box 302, the outer wall of the connecting column 309 is abutted against and slidably connected to the inside of the supporting seat 308, the supporting seat 308 supports the connecting column 309, thereby improving the lateral movement stability of the loading box 302, and the clamping column 310 is mounted on the outer wall of the connecting column 309. Example

[0029] On the basis of Example 1: the loading unit includes a support plate 301, a loading box 302, a mounting member 303 and a support wheel 304, the support plate 301 is installed on the inner wall of the drying box 1, the loading box 302 is arranged inside the drying box 1, the mounting member 303 is installed at the bottom of the loading box 302, the mounting member 303 and the support wheel 304 are symmetrically distributed at the bottom of the loading box 302, thereby improving the support efficiency of the loading box 302, the support wheel 304 is connected to the inside of the mounting member 303, the connecting end of the support wheel 304 is rotatably connected to the inside of the mounting member 303, and the outer wall of the support wheel 304 abuts against the inner wall of the support plate 301, so that the loading box 302 can be shaken more stably, thereby improving the stability of drying.

[0030] The drying mechanism includes a fixed plate 401, a machine frame 402, a fan 403, an electric heating rod 404, a heat pump fan 405 and a mesh tube 406. The fixed plate 401 is installed at the top of the drying box 1, the machine frame 402 is installed at the top of the fixed plate 401, the fan 403 is installed at the fixed end of the machine frame 402, and the fan 403 is distributed inside the machine frame 402.

The heating of the electric heating rod 404, the heat pump fan 405 and the mesh tube 406 generates heat inside the drying box 1. Under the action of the fan 403, the heat circulates inside the drying box 1, thereby improving the drying efficiency. The connection member 307 is rotated by the operation of the driving motor 306. Since the bottom end of the connection member 307 is engaged with the multiple groups of clamping columns 310, the connection column 309 is continuously moved horizontally through the back and forth swing of the connection member 307 and the connection of the multiple groups of clamping columns 310, thereby driving the charging box 302 to continuously move horizontally under the support of the support plate 301 and the support wheel 304, so that the grains inside the charging box 302 are more evenly heated and dried, thereby improving the drying quality.
