The Design And Research Of Sludge Paver For Rice Seedling Bed

As the main food crop in South China,rice is planted in large areas in the major rice growing areas of South China.The main planting method of rice is transplanting,and seedling raising is the most critical link of transplanting.The wet and rainy climate and the wet and sticky soil conditions in the south of China,the mud method has become the main field seedling raising method in the south of China.This kind of seedling raising method is still dominated by manual work,with high labor intensity,low working efficiency and poor quality of mud produced,which has affected the seedling raising effect,and has become a prominent problem restricting the development of rice planting.With the rapid development of rice planting industry,the level of rice planting mechanization is getting higher and higher.However,there are few spreading machines at home and abroad that are specially used for seedling bed slime seedling raising.Therefore,the research and design of a kind of spreading machine for seedling bed slime is of great significance to solve the shortcomings of manual operation,cater to the rapid development of Rice Mechanical Transplanting Technology in South China and accelerate the process of rice planting mechanization in South China Great practical significance.Based on the analysis and research of the existing relevant seedling raising equipment in combination with the relevant agronomic requirements,it is found that the existing seedling raising equipment or large volume is not suitable for working in the field,or it has to be participated in manually,and lacks of mobility;there are fewer seedling bed mud spreading machines integrating the three functions of mud preparation,mud collection and filtration,and mud spreading,and the machinery similar to the seedling bed mud spreading machine is rarely heard and has a single function In this paper,a kind of seedbed mud spreader is designed and researched,which is mainly composed of four parts: walking device,mud making device,mud collecting and spreading device.In order to reduce the damping of the machine,reduce the sinking depth of the whole machine and improve the working stability of the machine,the machine innovates the structure,integrates the walking device and the pulping device to form the paddy wheel assembly,uses the submersible mud pump to collect and spread the mud,and needs to bond the paddy soil before pulping Carry out soil breaking work,and install a soil breaking plow at the end of the whole machine.Through the proe 5.0 3D drawing software to complete the 3D design of parts and virtual assembly of the whole machine.This paper studies the damping problem of the paver in the working process,and analyzes the driving stability and anti rollover ability of the pulper by establishing the mechanical model.ANSYS finite element software is used to analyze the loading and deformation of rotary blade when making mud,and the modal analysis of paddy field wheel is carried out.Through the analysis of its vibration mode and frequency,the optimal design is carried out,and finally the assembly of paddy field wheel meets the design requirements.Finally,the paver prototype is made and field test is carried out,and the simulation results are compared and analyzed to optimize the performance of the whole machine.The research and design of the seedbed slurry paver not only reduces the labor,but also improves the working efficiency,which provides a reference for the development and application of rice slurry seedling cultivation in the southern hilly area.
