Virtual Assembly, Parametric Design, and Finite Element Analysis of a Peanut Harvester Digging System for Saline-Alkaline Soils

Purpose : The research tackles the problem of deep hard soil cropping areas because standard groundnut tools lack sufficient penetration to obtain satisfactory pod yields. Under hard soil conditions the YRDIA designed an improved groundnut digger to enhance its harvesting capabilities. Methods : Tough soil breaks through two particular shares equipped with chisel points which elevate peanuts toward the picking area at 110 degrees. The YRDIA optimized the digging tool specifically for bunch-type groundnuts grown using 60-cm row placement in dry areas where soil conditions are normally hard. Analysis of structural performance happened through SPH method integration with LS-DYNA software to simulate ground-cutting procedures at 15 cm depth. Results : During the test the digger generated 737 Newtons of force while the maximum steel material deflection was 1.48 mm and peak stress reached 85.738 Pa alongside minimal strain of 0.0004. A high concentration of stress and strain originated from the blade tip. Soil-cutting operations remained stable under conditions where the stress reached 3.210 MPa and the force exceeded 650 N. Testing confirmed the tool could handle hard soiling conditions and presented acceptable financial terms. Conclusions : A promising tool for deep and hard soil peanut harvesting exists in the form of the YRDIA groundnut digger. Due to its advanced design and durable structure and economical nature this tool delivers significant benefits to improve pod harvesting efficiency in harsh agricultural environments.
