Optimized design and experiment of a controllable rotary tube strip fertilizer spreader for hilly mountainous terrain.

ABSTRACT: The existing fertilizer spreader has suboptimal performance in terms of fertilizer uniformity, lack of controllability of fertilizer spreading width, low utilization rate, and inability to meet the requirements of hills, mountains, and other complex terrains. In response to these shortcomings, we have developed a rotary tube fertilizer spreader for mountainous terrain. This device uses a fertilizer trajectory based on the drop distribution of overlapping prolate cycloids, which enables uniform fertilizer application in both the transversal and longitudinal directions. Based on an analysis of the structure and operating principles of the device, Table L₉ (3⁴) was selected for orthogonal array testing, and the results showed that the transversal fertilizer distribution
