Design And Test Of Orchard Full Hydraulic Rotary Tillage Machine

In 2019,China’s orchard planting area totaled 184.15 million mu,and Hunan Province’s fruit planting area reached more than 8 million mu,with an output value of more than 60 billion yuan.With the continuous increase of fruit planting area and the transfer of rural labor force to cities,China’s fruit planting industry is facing great challenges.According to the relevant investigation,most of China’s orchards are in the state of unmanned management,resulting in China’s fruit yield per unit area is not high,relatively poor quality and many other problems.This article through to operational conditions and agronomic requirements of orchard in our province machinery research,developed a remote control of hydraulic crawler chassis,the chassis can carry rotary tillage ridging and vertical mowing machine,vertical rotary tillage operation equipments has the function of copying obstacle avoidance in the rotary tillage weeding work is automatically avoid the obstacles such as trees.This article according to the requirements and characteristics of the orchard on the hydraulic rotary cultivator chassis structure design,3 d modeling,mechanical characteristics analysis and finite element analysis,hydraulic and electric control system design,and the development of remote control hydraulic rotary rig to study in the orchard,vehicle speed and the rotation of the machine the best match.(1)analysis of the development of orchard rotary rig at home and abroad the latest research results of rotary cultivator and related enterprises,combined with the basic situation of orchard rotary cultivator at home and abroad and the related data of rotary cultivator standards,based on existing problems and related technical requirements for orchard rotary cultivator,and determine the research contents and technical route of this article.(2)According to the functional requirements of the orchard rotary tiller and the agronomic requirements of China’s orchard,determine the overall design scheme and performance parameter requirements,carry out the structure design of the orchard remote rotary tiller,hydraulic components of the parameter calculation and selection,establish the three-dimensional structure model of the orchard rotary tiller.(3)Carry out theoretical analysis for the orchard rototiller,conduct dynamic analysis on the chassis and key parts of the whole machine,calculate the basic structural parameters,carry out strength check,and analyze the selection of the entire hydraulic system to meet the driving requirements of the orchard rototiller.(4)The Simulation module of Solid Works2017 is used to carry out static mechanical analysis and static finite element analysis on the chassis and key parts.According to the strain,stress and displacement of each part,parameters are checked to optimize the part structure.(5)Performance test for remote control full hydraulic rotary tiller prototype.The tractability,passability and rotary tillage depth of the prototype were verified to meet the design requirements,and the optimal combination of chassis forward speed and machine rotation speed was determined.
