Optimization design and experimental analysis of bionic viscosity reduction of chisel type energy saving subsoiling shovel

Abstract

In order to solve the problems of adhesion to soil and high resistance in traditional subsoiling shovel operation, a bionic energy-saving subsoiling shovel with bionic viscosity reducing and resistance reducing chisel is designed based on the polygon geometry structure of pangolin scales. In this paper, the bionic modeling analysis of chisel type energy-saving subsoiling shovel is carried out by using 3D modeling software. According to the simulation analysis data, we optimize the key structural parameters, and try to produce the bionic energy-saving deep scarifier with reducing viscosity and resistance. In order to study the performance of the chisel type energy-saving subsoiling shovel, L9 (34) orthogonal test was carried out in the field with the number of bionic surfaces, coating materials and forward speed as the experimental factors, and the adhesion soil amount and traction resistance as the test indexes. The results show that the order of influence of each factor on the index is the number of subsoiling shovel bionic surface, coating material and advancing speed; the optimal horizontal combination is that the number of bionic surfaces of subsoiling shovel is 10, the coating material is UHMWPE, and the advancing speed is 6km/h.

Simulation and experimental study on drag reduction and anti-adhesion of subsoiler with bionic surface

“…Recently, biomimetic technology had been widely applied in agricultural equipment due to the ability to reduce tillage resistance and prevent adhesion [7][8][9] . Huang et al [10] developed a kind of bionic viscosity reduction of chisel type energy saving subsoiling shovel based on scale structure of pangolin, which solves the problems of clay and high resistance in traditional subsoiling process. The results showed that the number of bionic surfaces, forward speed and coating materials had no significant effect on the traction resistance; the number of bionic surfaces and coating materials had a significant effect on soil adhesion; the forward speed had a significant impact on soil adhesion.…”
