The Research On Oscillating Processing Tomato Fruit-stock Saparation Mechanism

With the development of the Western Movement and village economy, as a kind of agriculture cash crop, tomatoes'plant area is continuously extension. To solve this tense condition of lack of labor force for picking, at the same time to realize the mechanization of tomato, this essay makes a search on the core part of picking machine-the fruit-stock separation device. It draws lessons from the research achievement of the abroad separation device to design the fruit-stock separation device. The essay mainly analyzes sport characteristics and its impact factor of lacking of impartiality organization to design an adjustable type of separation device. It gets valuable structure, parameter, and analysis method for the development of physical kind machine and product and it provides a theory foundation for the harvest machine in domestic in some way.The main content of essay includes:1) Carrying on a thorough research on the separation mechanism of the tomato fruit-stock separation device, acquainting with sport characteristics and impact factor of the device; going to the field to carry on on-the-spot diagraph of the tomato fruit dint needed for separating stock, and acquired an original data. Applying a profession experiment data analysis software-DPS carry on a processing through measuring to get data and let up measure an error margin and reckon more reasonable data, and draw up a data curve equation to provide basis for movement parameter.2) carrying on an accurate design calculation to the synchronous wheel form, acquiring related size parameter, providing size source for the establishment of model, making use of Pro/E to realize the 3D entity design software to complete separating device for all models of spare prates, and carrying on the virtual assemble that separates organization spare parts, and carrying on initial analysis-interference the analysis and quality analyze to form the virtual model of the fruit-stock separation device.3) Carrying on thorough analysis for kinetics and dynamics of separation organization, and drawing simplified dint to fasten the distribution diagram, making use of the knowledge of theory mechanics, fastening to carry on a simplification n to the dint, getting end mechanics model to make sure to the main factor of acceleration is the distance that is apart from planet stalk, thus designing the partiality piece of adjustable type organization, satisfying different needs for tomato species'acceleration requirements.4) Making use of Mech/Pro connection software to solve data exchange problem between Pro/E software and ADAMS software. Ducting model data which is built in the separation organization into ADAMS software form the Pro/E, to make use of ADAMS software to separate the organization on kinetics and dynamics analysis, getting the relevant curve of roller, then setting design changeable data and excellent aim, carrying on to the organization excellent turn, finally satisfying the premise of separation request to assure the best position of partiality piece.
