[0028] The first uniform distribution box 2 is provided with a first uniform distribution device, the first uniform distribution device comprises a plurality of uniform distribution plates 21, the uniform distribution plate 21 is a reverse V structure, the discharge end of the uniform distribution plate 21 is located on the front side and the rear side of the uniform distribution plate 21, and the material is uniformly distributed into each channel when passing through the plurality of reverse V structure uniform distribution plates 21, so that local overload or blockage of the material is avoided. The second uniform distribution box 3 is provided with a crushing device and a second uniform distribution device. Since the sizes of the materials are inconsistent or have large differences, the crushing device crushes the materials to improve the uniformity of the sizes of the materials. The discharge port of the crushing device is in communication with the feeding port of the second uniform distribution device. The second uniform distribution device comprises a first uniform distribution assembly, a second uniform distribution assembly and a third uniform distribution assembly. The first uniform distribution assembly, the second uniform distribution assembly and the third uniform distribution assembly are sequentially arranged from top to bottom, and the top of the first uniform distribution assembly is in communication with the bottom of the crushing device. The crushed materials sequentially pass through the first uniform distribution assembly, the second uniform distribution assembly and the third uniform distribution assembly, are uniformly distributed in the transverse direction, and then enter the flour mill to be ground,

[0029] In some possible embodiments, the plurality of uniform distribution plates 21 are arranged in a triangular lattice model, that is, in the order from top to bottom, one uniform distribution plate 21 in the first row, two uniform distribution plates 21 in the second row, three uniform distribution plates 21 in the third row, and so on. The upper uniform distribution plate 21 is located on the center line of the next row of two uniform distribution plates 21, and the top of the lower uniform distribution plate 21 is located on the extension line of the inclined plate on one side of the previous row of uniform distribution plates 21, so that the materials sliding from the two sides of the upper uniform distribution plate 21 can be uniformly distributed by the lower uniform distribution plate 21 again, and then fall from the two sides of the lower uniform distribution plate 21 into the second uniform distribution box 3. The material is uniformly distributed in the longitudinal direction by passing through the plurality of rows of uniform distribution plates 21.
