摘要
果实的采摘必须克服果柄与果实的连接力,为揭示番茄果实采摘力的大小及变化规律,试验测定番茄果实拉伸采摘力和扭转采摘力矩,得出成熟加工番茄拉伸采摘力大小与采摘作业时果实的运动方向有关。果实沿某一方向运动时,果柄受拉伸倾斜角度越大,采摘力越小,且番茄果实的采摘力与拉伸倾斜角线性相关,采摘果实时果实的不同运动方向,采摘果实做功相同;对于果柄粗短、刚度大的果实,扭转采摘果柄转角较小,果实容易采摘。
As fruit picking must overcome the connection force between fruit stalk and fruit,the tensile force and torsion moment of tomato picking were measured by test for revealing the size and its change of tomato fruit picking force during tomato fruit picking practice.The test results show that the size of the ripe processing tomato picking force is related to the movement direction of the fruit in picking operation.When the fruit is moving in a direction,the picking force is smaller with the tilting angle of the stalk being greater,the force of tomato fruit picking has a linear correlation to tensile inclination angle,and energy consumption of picking fruit is the same at different fruit moving directions.For the fruits with short and high stiffness stalks,the turning angle of stalk is small and the fruit is easy to be picked.
