Design of Rape Plot Belt Type Precision Seed Metering SystemDesign of ZP275 Turntable
[Abstract] This design is mainly used for farmer's field sowing and facility planting and sowing. Additional devices can also be used for fertilization, raking,weeding and other field operations. The structure and composition of the seeder and the forms, requirements and functions of its components are introduced in detail. This paper introduces in detail the power device of electric small-sized seeder and the requirements of its components, including the power selection of the seeder, the selection and size of the mechanical transmission, the design of the meteringwheel, the design of the fertilizer meteringwheel, the design of the ditcher, the design of the shaft, the design of sprocket, the design of other components, theworking requirements of the seeder, the preparation before sowing and the use of the seeder, etc. The design considers that the sowing depth can be adjusted continuously, the row spacing can be adjusted continuously, the hole spacing can be adjusted, the seed breakage rate and the sowing uniformity meet the national standards. The design considers practicality and economy, so as to achieve the goal of reasonable structure, low production cost, low energy consumption, high efficiency and easy operation.
