| Abstract: |
| With the research and development of agricultural soil-touching machinery, some scholars have found that the resistance and abrasive wear reduction performance of agricultural soil-touching implements is closely related to their own work efficiency, work quality and service life. Therefore, the reduction of soil adhesion, work resistance and abrasive wear has become a hot issue that urgently needs to be solved in the field of soil-touching agricultural implements nowadays. Bionics has the advantages of practicality, wide application, stability, the most cost-effective biotechnology-based system, flexibility and reliability, etc., and has become a new direction for realizing research innovation in the fields of medicine, architecture, and mechanical industry. Structure bionics, non-smooth surface bionics, bionic structure composite coating is an important branch of bionic drag reduction and anti-wear theory, since the creation of bionics theory, drawing on the unique geometric structure of soil organisms surface, geometric structure shape and special function design bionic soil touching machinery, through the plants and animals unique function and body structure to get the inspiration to prepare bionic coatings, to realize the bionic drag reduction and wear resistance from the natural organisms to man-made functional surface bionic has been gained wide attention and development. This review focuses on the three types of bionic coatings, including structure bionic, non-smooth surface bionic and bionic structure composite coating, in agricultural soil touching implements from the perspectives of numerical simulation, soil trench test and field test, with specific comparative performances and their resistance and anti-abrasion mechanisms, summarizes the related research progress at home and abroad, introduces the principle of bionic, characteristics, bionic objects, detailed bionic data extraction and the process of bionic design and preparation of bionic implements, and exemplifies the latest scientific research results and application effects. The latest scientific research results and application effects are summarized to provide newer and more comprehensive references for the current and more in-depth exploration of bionic soil animal drag reduction and anti-wear research. Finally, the problems of the existing bionic research on agricultural soil touching implements are elaborated. In order to improve the above mentioned implements resistance and adhesion resulting in serious energy consumption, as well as wear and tear faster resulting in increased implements failure, better adapted to the development of agricultural touchdown machinery high efficiency, low loss, agricultural touchdown implements bionic technology in the future development direction will be:1. Numerical analog simulation, soil tank test and field test combined with the test, the implements numerical simulation of the relevant parameters as far as possible to take the material to measure, to ensure that the Reliable performance of the final design of the machine tool; 2. According to the bionic object drag reduction and wear-resistant tissues and organs of the macroscopic microstructure, material composition and behavioral coupling, etc., systematic structure, morphology, function and coating bionic application, multifunctional cross-bionic design, the use of advanced preparation technology combined with bionic materials to prepare bionic implements with better performance, and to improve the performance of the implements to reduce the drag resistance and wear resistance through the bionic of a high degree of similarity; 3. Accelerate the research on the field of bionic intelligence, to Improve the development level of intelligentization and automation of agricultural machinery. |
