Design And Research Of Processed Tomato Filming Machine After Transplanting

Filming after transplanting is a new cropping patterns, combined with the advantages of ditchingtransplanting and mulching. Processing tomato acreage increased year by year. Seedling transplantingtechniques and mulching technology used more widely. Membrane transplanting currently exist issuessuch as low rates. This new cropping patterns for solving the above problem has a certain value andsignificance. Developing filming machine after transplanting is very urgent.In this paper, processed tomato filming machine after transplanting design parameters of the wholestructure, simulation analysis of filming agency, tensile properties experiments and filming agenciesphysical prototype experiments including the following aspects:(1)Structural design and analysis. Overall design scheme is put forward and Key components ofstructural parameter design and analysis is finished. Designing Protect seedlings plate based on themorphological parameters of processing tomato seedlings, width100mm, height100mm. Pressuring filmroller with a radius of110mm. When the spiral width B take75mm, mulch lateral force balance. When theconveyor belt width180mm, it meets the soil delivery requirements.(2)Filming Mechanism Simulation Analysis. Using of solidworks established Filming Machine aftertransplanting. The virtual prototyping, through interference checking, no interference. Using the RecurDynto simulate and analysis models under different laying Angle. When the laying angle is0°, film folding.Through the contact force curves when the laying angle is20°-30°,the contact force is small.(3)Plastic tensile test. According to plastic tensile orthogonal experiment, the significant factor forpull-off force is the width of the film. Significant factor for elongation is sawtooth pitch. At condition ofa symmetrical sawtooth distribution, larger sawtooth pitch, wider film width, the film performances better.(4)Filming agencies physical prototype experiment. Studies have shown that the significantly factorfor film motion state is tilt angle of protect seedlings plate. When the tilt angle of protect seedlings plate is30°,mulch laying angle20°,mulch laying speed800mm/s, the film fully opened, sticking on protectseedlings plate.
