Abstract

The invention relates to a bionic multi-scale spinule structure based on the fractal theory, and belongs to the technical field of agricultural machinery. Multiple spinule structures provided by the invention are sequentially distributed on a bionic convex hull structure based on the fractal theory according to fractal dimensions in a multi-scale manner, and are arranged in an array. The bionic multi-scale spinule structure combined with the bionic convex hull structure is used for the surface of a soil-engaging component of irrigated field equipment, wherein the bionic convex hull structure itself has anti-sticking and drag-reducing capabilities for dry field; and by adding the bionic multi-scale spinule structure based on the fractal theory, the soil-engaging component of the equipment can have anti-sticking and drag-reducing capabilities for irrigated field, so that the agricultural equipment can operate better in the irrigated field. The bionic multi-scale spinule mechanism can achieve better anti-sticking and drag-reducing effects in the irrigated field having high viscosity, thereby ensuring the operation quality, reducing the energy consumption and saving the production cost.

Description

technical field [0001] The invention relates to a bionic multi-scale microthorn structure based on fractal theory, which can be combined with a bionic convex hull structure, is suitable for the surface geometry structure of soil-contacting parts of paddy field machinery, and belongs to the technical field of agricultural machinery. Background technique [0002] In the process of contacting the soil-contacting parts of modern agricultural machinery and tools with the soil, reducing the adhesion and resistance when in contact with the soil has always been the research direction of scientific and technological personnel on the soil-contacting parts of modern sandy soil machinery. When the soil interacts with the soil-contacting parts of the implement, the soil may adhere and accumulate on the surface of the soil-contacting parts, resulting in greater resistance. In addition, when the soil-contacting parts of the implements are in contact with the soil, there will be a lot of fr...
