After the material on the auger 130 falls into the material collecting box 150, as the two crankshafts 322 respectively drive the two connecting plates 210 to alternately move up and down, when the feeding plate 220 at the lowest side on the left side is lower than the lower side of the baffle 152, the material in the material collecting box 150 enters the feeding plate 220, and when the moving rod 230 rises to be abutted with the stop block 111, the moving rod 230 drives the feeding plate 220 to rotate towards the lower side, so that the material on the feeding plate 220 falls onto the feeding plate 220 at the other side, and the reciprocating manner is realized, so that the material is driven to rise, and is conveyed to the upper end of the auger 130 through the discharge chute 112, so that the material is circulated.

Meanwhile, the transmission shaft 320 drives the fan blades 400 to rotate, so that the hot air collected at the upper part of the drying box 100 is blown to the inner lower side of the separation box 110, and the hot air circularly flows between the drying box 100 and the separation box 110, and the circulation direction of the hot air is opposite to the circulation direction of the materials, so that the full and effective contact and drying are realized. In the present application, unless explicitly stated or defined otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as fixed connections, as well as removable connections, or as one piece; may be mechanically connected, may be electrically connected or may communicate with each other; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

While preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
