Abstract:The three-dimensional dislocation cultivation system of factory hydroponic lettuce can be developed on the basis of increasing the number of cultivated plants per unit area without affecting the light of lettuce.To improve the mechanization rate of the system and reduce labor intensity, according to the characteristics of the three-dimensional dislocation cultivation, the planting cup was proposed to raise to a certain height before pushing the planting tray, and the colonization cup could cross the cultivation trough plug. The colonization tray was pushed up the cultivation trough, and a set of planting tray handling equipment was developed. Taking the lettuce colonization tray as test object, the Box-Behnken experimental design method was used to explore the factors affecting the success rate of the handling equipment on the plate, and the optimal parameter combination was discussed. The test results show that when the horizontal installation error of the cultivation tank is 0-5 mm with the guide plate angle of 60° and the advancing speed of 0.22 m/s, the largest success rate of the upper plate of 99.33% can be achieved, which can meet the three-dimensional dislocation production requirements of factory hydroponic lettuce.
