Functional Structure Modeling and Assembly Practice of Ditching Fertilizer Based on Standardized Module Design

In the existing agricultural machinery field, the agricultural machinery is generally cumbersome, the transportation, disassembly and assembly, maintenance procedures are more complicated, and the functions are single, and the versatility is not good. This article combines the industrial design standardization and modularization ideas for the trenching fertilizer application machine. Model construction and assembly practice were carried out. The whole machine was built according to independent functions, and divided into racks, fertilisers, trenching assemblies, suspension systems, transmission systems, etc. Modeling of the rack, modeling of the fertilizer turntable, and plowing the modeling process is elaborated. By assembling the functional components and standard parts, the modular design idea can be reused and exchanged in the design of the trenching fertilizer machine. The relevant modules can form the final product through the arrangement and combination. The final assembly entity can be a variety of products, which can better meet the customer's customization needs; the repetitive use of similarity can make the whole product more convenient in manufacturing and maintenance, and the overall machine coordination and appearance are more beautiful.
