The Design And Research Of Small Drum Sieve Type Peanut Harvester

Peanut is one of the main oil crops in the world,are major peanut production areas in China,but has always been to peanut harvesting mechanization overall level is not high,the artificial operation not only high labor intensity,low efficiency,yield loss is big,and take up farming,which restricts the peanut production in China,seriously affected the enthusiasm of farmers friend peanut planting.While the existing peanut harvester is still stuck huiyong,soil,poor soil separation effect and so on a series of problems.According to our country’s present situation,development characteristic of peanut harvesting machinery,promote our country agriculture has great significance to the early realization of mechanization.Our country at present,the investigation of peanut harvester,suitable for the hilly region of sectional small peanut harvester according to its working principle is mainly divided into three categories,one is mining combined with separation,such as 4H-2;The second category is the scraper chain combination,such as 4H-800;The third type of shovel sieve combined,such as 4H-700.They each have advantages and disadvantages,the performance of the above problems,the author of this paper and the development status of the existing small peanut harvester explore design research and development on the basis of a southern hilly area small drum sieve type peanut harvester.The sieving effect are good drum sieve is applied to the peanut harvesting machine,the overall structure compactness,low consumption,fruit soil separation efficiency has improved greatly,high efficiency,low power consumption characteristics.At the same time,the machine can adjust the height of the limit depth wheel to adjust the Angle of the grave and digging depth of digging shovel,digging shovel to ensure optimal Angle,reduce the working resistance of digging shovel.This article also on the working principle of the machine,the digging shovel of soil,the paper analyzed the principle and the whole machine structure design summary the effects of technical parameters on the machine performance,and optimization analysis,determine the best parameters,through the movement simulation,mechanics analysis and modal analysis to verify its feasibility.By AutoCAD and solidworks2014 complete the parts design and virtual assembly,compares the advantages and disadvantages of existing digging shovel,combined with the advantages of existing digging shovel and satisfy the demands of the machine structure,design a new digging shovel.Use ansys software to analyze of the forced state of a key components,from the displacement nephogram and strain nephogram and find the position of loading dangerous stress nephogram,the digging shovel,frame and connection parts to optimize design.Modal analysis was carried out on the rack,solving the frame of the natural frequency and vibration mode figure,at the same time avoid the resonance,the structure is improved from the Angle of mechanics and vibration study Angle can satisfy the requirements of design.Finally,ADAMS software is used to simulate the movement of the roller screen to verify the feasibility of the motion plan and to get the best forward speed of the whole machine.Small drum screen type peanut harvester,a complete mining sieve soil,laying,and other functions,its design to provide new train of thought for the similar machinery research and development design,its good performance and can reduce the labor intensity of farmers and improve production efficiency.
