Design And Experiment On Precise Seed-Metering Device For Rape

Rape is important edible oil crops in China. At present, the rape production in China still use firstly artificial or half mechanization operation mode of operation and the intensity of labor is big and efficiency is low. For rape planting machine, the most key components for metering device. Rape seed metering device in our country at present stage to rape the little seed is difficult to achieve precise seeding. And rape seed metering situation should not be observed. If the line appears uneven displacement, replay, sowing conditions such as leakage, after the late seedling, difficult to handle, certain economic loss. Thus developing a precise planting of rape seed metering device is necessary.In order to complete the rape of precise design improvements, first determine the working principle of the metering device circuit design technology. Know about the characteristics of rape seeds and agronomic requirements of rape seed, rape seed precise metering device for design.First through PROE to various kinds of machine parts design, some key components of the row of kind of shaft in ANSYS intensity, the parts design is completed and all parts are assembled. Metering device is assembly after the completion of the whole. Rape seed metering device type makes kinematics simulation in the hole under environment of Pro/mechanism. Finally finish the rape of precise design.The rape seed grain is small and unfavorable to observe the characteristics of the case,. The color discrimination degree is not high, we design rape seed metering device detection device. The various components of the design mainly include the design of the detection device shell, hardware circuit and software design. After the completion of the design of detection device can well the real-time status of rape seed testing.Complete design of rapeseed precise. Rape seed precise make experiments on rape seed metering device to detect the metering performance. Based the two kinds of rape on the experiment, the experiments mainly includes the single factor experiment and orthogonal experiment. Single factor experiment factors include kinds of spindle speed, type hole, clear way, cleaning, gas pressure and gas blowing Angle. Ultimately the single factors determine the row of single optimal solution. Orthogonal experiment determines the optimal combination of the single factor experiment. The experimental results showed that qualified, replay index, leak seeding index achieves metering requirements.
