Abstract: Agricultural materials directional transportation pretreatment technology is an important means to improve the degree of automation of agricultural product processing, and the fixed posture before the processing of agricultural materials can effectively reduce the damage rate of agricultural products processing and improve the processing efficiency of agricultural products. Therefore, the research progress of domestic agricultural material directional transportation pretreatment technology is analyzed, and the methods of directional conveying of rolls, vibration directional conveying and directional conveying of transmission belts are compared and analyzed to clarify their orientation mechanism and equipment applications. Through comparative analysis, it can be seen that the current directional pretreatment technology of agricultural materials in China is not mature enough, the standardization degree of related directional conveying devices is low, the adaptability is poor, and the relevant basic research is insufficient. In view of the above problems, the research on the physical characteristics of agricultural products should be strengthened in the future, the adaptability of the directional conveying device should be improved, and a variety of directional conveying pretreatment technologies should be adopted to improve the success rate of orientation in the processing of agricultural products.

Key words: agricultural materials, directional conveying technology, directional conveying device, orientation principle
