Abstract: In response to the problem of the plow, which is unable to achieve deep plowing and is capable of deep plowing due to the characteristics of soil overturning, and is not suitable for facility greenhouses, this paper designs an insitu tilling plow based on reverse engineering technology. The GMSCANH handheld laser 3D scanner was used to scan the BT-25 plow, obtain point cloud data, and use the reverse design software Geomagic Design X to construct the surface of the plow body and other working components, completing the 3D modeling of the local soil turning plow. The samples of scaled model was printed by 3D printing technology and the soil tank test was carried out. The test results showed that the insitu tilling plow designed by reverse engineering technology had a soil falling rate of 903% in the original ditch. The threedimensional model established provided a reference for further research and optimization of insitu tilling plow in the future.

摘要： 针对当前设施农业耕整作业大多采用旋耕法无法实现深翻而能够深翻的铧式犁存在土垡侧翻特性使其不适用于设施大棚的问题，基于逆向工程技术创新设计就地翻土犁。选用GMSCAN-H手持式激光三维扫描仪对BT-25型铧式犁进行扫描，获取点云数据，并通过逆向设计软件Geomagic Design X构建就地翻土犁犁体曲面及其他工作部件，完成就地翻土犁的三维建模。利用3D打印技术打印其缩放模型并进行土槽试验。试验结果表明：应用逆向工程技术设计的就地翻土犁，原沟落土率为903%，所建三维模型为后续就地翻土犁进一步研究和优化提供参考。
