Design Of Corn Stalks Mulching And Returning Machine

The number of crop stalks in China is increasing year by year.Returning stalks to farmland can increase soil fertility,save costs,and increase crop yields.Since corn stalk contains a large amount of organic matter,the roots of subsequent crops cannot be completely absorbed if they are directly returned to the field,and rot roots,diseases and insect pests,and low yields will occur.The decomposing agent contains a variety of highly effective microbial bacteria that can be used as corn stalks.Organic matter in the organic matter is converted to inorganic matter for better plant absorption.Realizing resource recycling.Through market research,it has been found that there is no mechanized corn stalk maturing and returning equipment that can be used together with the return of corn straw and composting agent.According to the requirements of the project,a corn stalk mulching and returning machine for corn stalks that can be used for poly ridges,row sterilizing,repression and earth covering operations at one time was designed.This paper combines the agronomic process and the existing straw returning machinery to design the whole machine and select the type of parts;The design and calculation of the operating parameters of the main working part finger dials.In order to reduce the amount of grass wrapped around the fingers,ensure the efficient operation of the finger plate,set a declination in the direction of the finger plate and the forward direction,set a tilt angle between the finger plate and the ground,and obtain the finger plate by calculating the trajectory of the elastic tooth.The best working declination and inclination;using SolidWorks software to carry out three-dimensional solid modeling and assembly of the whole machine parts,check whether there is interference in the assembly of the whole machine.The corn straw mulching and returning machine designed in this paper satisfies the design requirements and meets the market demand,effectively improves the quality of straw returning,increases the crop yield,and lays the foundation for practical production and application of straw mulching equipment.
