Design And Test Of Rotary Type Salvia Splendens Potting Mechanism

With the acceleration of the process of urbanization in China,the construction of urban landscaping is gradually advancing.potting flowers are often used to decorate festivals and beautify the environment because of their ornamental nature;At the same time,because of their short-term effectiveness,potting flowers have a great market demand.The main planting method of potting flowers is plug seedlings,which means that the seed is sown in the plug tray with a precision seed drill.When the seedlings grow to a certain size in the plug tray,the seedlings are moved from the plug tray into the pots,a process known as "potting." This cultivation method can improve the survival rate of flower seedlings and maintain the unity of the crop quality.However,artificial pots have a large workload,high labor intensity and low work efficiency.Therefore,it is of great significance to develop a low-cost supporting flower potting plant instead of artificial transplanting for liberating the labor force,improving the quality and efficiency of potting plants,and realizing the scale of the flower industry.The flower potting equipment developed by developed countries such as the Netherlands is at the international advanced level.The device imitates the technology and structure of field crop transplanting equipment for economic crops,and uses the results of mechatronics brought by information technology.The manipulator has a complex structure and high cost.This kind of equipment is mainly used in large-scale and intensive agricultural production mode,and it is not adaptable to the current domestic facility agricultural production mode.The whole set of equipment is expensive,and most of the domestic flower and fruit and vegetable production bases cannot afford it.This article relies on the optimization design platform of the research group to design a rotary salvia splendens potting mechanism that can realize flower pot seedling potting.The theoretical model of the potting mechanism was established,and on this basis,a visual computer-aided analysis software was prepared,and the application software was used to complete the parameter optimization.According to the optimized parameters,the two-dimensional model of the mechanism was designed in CAD and the three-dimensional model was established and assembled in UG.The specific research content of this paper is as follows:(1)The analysis of the research status of potting mechanism at home and abroad,aiming at the existing structure of potting plants existing in existing potting mechanism which is complicated in structure and high in electromechanical control cost,this paper proposes a revolving protruding red potting mechanism.The mechanism uses non-circular gear planetary gears in combination with a potting arm equipped with a probe-out seedling device to meet the pot trajectory and posture requirements that are not satisfied by a general rotary transplanting mechanism.(2)The introduction of the working principle of a series of red potting mechanism.Taking the seedling device and the potting arm as a whole,the kinematics analysis of the potting mechanism was carried out,the theoretical model of the potting mechanism was established,and the displacement,velocity and acceleration of the seedling tip of the potting mechanism were theoretically analyzed and calculated.(3)A number of optimization objectives to be satisfied by the potting mechanism were determined,and the computer-aided analysis method was used to solve the multi-objective and multi-parameter complex optimization problems of potting mechanism.On the basis of the theoretical model of the pot mechanism established above,the VB platform was used to develop potting mechanism optimization software,and various functions in the software were introduced.The influence of changes in various parameters of potting mechanism on the cusp trajectory of the seedling film was analyzed.A set of non-inferior solutions satisfying the potting mechanism requirements was optimized.(4)Based on the optimized parameters of the potting mechanism obtained by the above optimization,the potting mechanism is designed.First,the overall layout of the potting mechanism was completed using AutoCAD,and the design of potting arm and other important components was completed according to the corresponding institutional parameters,and the two-dimensional map of the potting mechanism parts was drawn.(5)The use of NX8.0 software to complete the formation of the drive gear in the potting mechanism,and the three-dimensional modeling of the parts in the potting mechanism,and completed the assembly of the virtual model of the potting mechanism.The assembled model was subjected to interference detection to prepare for the trial production of the physical prototype of the subsequent potting mechanism.(6)With the help of the 3D printing technology,the time for mold opening is saved,and the rapid prototyping of the physical prototype of salvia splendens potting mechanism is completed,and the assembly of the physical prototype is completed.A high-speed photography experiment was designed and the cusp trajectory of the seeding film was compared with the theoretical trajectory to verify the correctness of the design.Finally,a rotary salvia splendens potting mechanism test stand was built and the seedling test was completed.
