Design Of Screw Cutting Tree Transplanting Machine And Parameter Research On Working Parts

It’s very urgent to develop a simple, convenient and reliable portable tree transplanting machine, which can replace artificial seeding transplant for our nation’s booming but poor mechanical nursery industry. In this paper, horizontal milling type tree mover and spiral drilling type tree mover had been designed. Father more, in order to obtain machines’ better working performance, the operating parameters of spiral milling pipe and spiral drilling pipe was studied and optimized. Thus, several parts as below mainly contained by this paper:(1) Milling experiments based on spiral milling pipeThrough a series of experiments, the effect of the operating parameters of spiral milling pipe to milling performance was grasped. And the correctness of spiral milling pipe was also verified.(2) Structural design of horizontal milling type tree mover and proofreading of key partsThe horizontal milling type tree mover was designed based on the Creo2.0software. According to the architectonics, dangerous section was proofread through the force analysis.(3) Finite element analysis on spiral milling pipeThe milling simulation of spiral milling pipe was completed based on the ANSYS/LS-DYNA13.0software. The milling power for gasoline engine and energy consumption below certain roller speed and feed speed were confirmed by the analysis of LS-PREPOST software.(4) Structural design of spiral drilling pipeThe response surface between the structural parameters of spiral drilling pipe and the soil particle vertical speed was drawn by based on the MATLAB11.0software. Through the further linear programming for the constraint condition of soil kinematics, the maximum load was calculated out.(5) Structural design of spiral drilling type tree moverThe spiral drilling type tree mover was also designed based on the Creo2.0software.
