Design and Experiment of Integrated Fertilizer Machine for Camellia Oleifera Orchard
Aiming at the problems of single operation function,inflexible movement,insufficient power and unstable and unqualified tillage depth of the existing small trenching and fertilizing machine in camellia oleifera orchards in hilly mountainous areas,the integrated fertilizing machine suitable for digging and fer-tilizing and mulching in camellia oleifera orchards is developed and researched.The parameters and work-ing principle of the machine were introduced;the design of the cavity digging drill and the analysis of the movement of the lever feeder during the cavity digging process were carried out;and the reasonable size of the frame and handrail made it easy for manual operation;the outer groove wheel type fertilizer discharge with simple structure and stable fertilizer discharge was selected and the size of the fertilizer discharge de-vice was designed to meet the agronomic requirements;the mulching plate with adjustable height and an-gle to better fit the ground was designed to increase the levelness of the mulched soil.The experimental re-sults show that the machine has good operational performance,with flexible movement,good turning per-formance,simple operation and low labor intensity;the average digging depth is 203.1 mm,the coefficient of variation of digging depth is 3.2％,and the relative error between theoretical and experimental fertilizer discharge volume of external slotted wheel type fertilizer discharger is 1.7％,which meets the agronomic requirements of oil tea orchard fertilizer chasing overall.
