一种仿蚯蚓波纹润滑体表减阻开沟器

本发明公开了一种仿蚯蚓波纹润滑体表减阻开沟器，是由护种罩、铧柄、芯铧和输种管组成，输种管固定设置在护种罩后端，铧柄固定设置在护种罩前端，芯铧后端具有翼板，护种罩、铧柄和输种管分别固定设置在芯铧上；本发明采用蚯蚓头部收缩态曲线进行仿生，因为蚯蚓的收缩态头部是进行破土钻土过程中与土壤最先发生作用的部分，所受的强度最大，是入土的最关键部分，蚯蚓体表试样的减粘降阻效果由大到小依次是：收缩态、静息态、舒张态，且头部试样比体部试样减粘降阻效果明显。本发明能够完成波纹形态体表与润滑作用相结合，实现二元耦合，能够减小土壤粘附，降低开沟阻力，且结构简单，入土性能好，强度高，工作效率高，开沟质量高。 The invention discloses an earthworm simulated corrugated lubrication body surface resistance reduction groove opener, which consists of a seed protection cover, a ploughshare handle, a core ploughshare and a seed conveying pipe, wherein the seed conveying pipe is fixedly arranged at the back end of the seed protection cover; the ploughshare handle is fixedly arranged at the front end of the seedprotection cover; the back end of the core ploughshare is provided with a wing plate; the seed protection cover, the ploughshare handle and the seed conveying pipe are respectively and fixedly arranged on the core ploughshare. The earthworm head shrinkage state curve is used for simulation; the earthworm head shrinkage state head
