In response to the issues of high energy consumption, limited functionality, and uneven soil–fertilizer mixing in mechanical operations for trenching fertilizing hilly orchards, this study proposes design a crawler-type self-propelled machine, integrating three main functions: trenching, fertilizing, soil covering. The key components device, soil-covering device were designed. Three simulation models (pre-plant, mid-plant, post-plant) established using EDEM discrete element software. effects under each mode analyzed, with results indicating that post-plant better meets requirements deep organic fertilizer application. Using speed, forward bending angle knife as experimental factors, operating power consumption uniformity evaluation indicators, Box–Behnken experiment was conducted optimize parameters components. A regression model analyze interaction between factors indicators. optimal operational parameter combination determined follows: speed 265.03 r/min, 0.40 m/s, 130°. Under these parameters, 1.74 kW 77.15%, respectively. Orchard verification tests on machine showed relative errors field simulations 7.40% 4.50%, These meet agronomic provides valuable references application related technologies orchard operations.

This study developed a chain counter-rotating trenching and backfilling device to reduce high tillage resistance in orchard operations. A 3D mathematical model of the blade was created using Cartesian coordinate transformation. Taking curvature (β), curve angle (α), bend radius (R), cone residual (θ) as experimental factors, soil cutting evaluation index. The optimized parameters were β=95°, α=10°, R=24 mm, θ=39°. Bench tests performed with optimal parameters, results showed that ditching reduced by 18.7% compared ordinary blades. Field test 9.64% reduction furrowing torque.
