Bionic potato digging shovel capable of reducing viscosity and resistance

The invention belongs to the technical field of agricultural machinery, and relates to a bionic potato digging shovel capable of reducing viscosity and resistance. The bionic potato digging shovel isdesigned on the basis of a bamboo rat tooth structure and a soil accumulation nucleation phenomenon, a soil entering section is of a pentagonal plane structure, and a ridge structure designed on the basis of the soil accumulation nucleation phenomenon is arranged at the front face of a soil lifting section; the longitudinal section of the soil lifting section is of a bionic curve structure, and amounting section is of a cuboid structure; and the soil entering section, the soil lifting section and the mounting section are sequentially arranged from bottom to top and are smoothly connected, andthe soil entering section, the soil lifting section and the mounting section are each of a symmetrical structure about the upper center line ae of the digging shovel. The bionic potato digging shovelcan effectively reduce adve
