Research And Experiment Of Multi-purpose Single Seed Drilling Technology

Precise sowing has time-saving, the labor saving, the province plants and the production increase merit, is the work development direction. The precise seed sowing device is the key component that influence precise sowing quality, enhances the seeder the year use utilization ratio is the important link which the precision seeder develops, also is a hot spot which the present farm machinery scientific and technical worker studies.The precise seed sowing device basis its principle of work may divide into the mechanical type and the physical strength type. Regardless of the mechanical type or the physical strength type, the common shortcoming is they cannot be suitable to sow different kind of crops' seed, by enhances the seed sowing device the year utilization ratio, increases the income of the farmer.This topic carries on the thorough research analysis in the consult massive literature material and to the domestic and foreign existing precise seed sowing device, proposed one kind of multi-purpose single seed and accurate seed sowing device, and conducts the research to the technical mechanism of the device, theoretically proves its single seed, multi-purpose, the high efficiency row of scientific nature, the serviceability, the efficiency.First, analysis the geometry parameter and the shape characteristic of the corn, the wheat and the soybean which uses to this topic laboratory.Next, take seed geometry parameter and shape characteristic analysis as foundation, determine various designing parameter and performance parameter of the seed sowing device, including: cell plate diameter, cell shape, cell parameter, cell number and cell arrangement way and so on. And analyzes the process of sufficient and clear and the request of protect plants and throw plants, the reasonable determination related to sufficient and clear of technical influence essential factor, completes structural design of the seed sowing device.Finally, determines the seed sowing device through the experiment that the different seed surface in the seed box and the different rotational speed of the seed sowing device, the corn, the wheat, the soybean seed's displacement stability and feed uniform under the different velocity ratio condition and so on the actual effect, and builds the foundation for further improves.
