模拟手枸杞采摘机设计

Design of simulate hand wolfberry picking machine

为解决现有采摘机对果实损失较大以及采摘效率低等技术问题,根据枸杞果实成熟自然特性,设计模拟手枸杞采摘机。手持采摘头内两旋转体的表面相对称凸出设有若干胶环。两旋转体通过直流电机的传动进行相对运动,实现了模拟人手采摘动作采摘果实。整机性能测试结果表明,手持采摘头质量约300g,直流电机转速在120r/min,运行平稳可靠,采摘枸杞果时对树叶和不成熟果实没有损伤,不影响采后产量和生长。每小时可采摘成熟枸杞果15～20kg,而每小时手工采摘成熟枸杞果只有2～3kg。该机具可以满足大面积枸杞采摘的需要,采摘速度是人工的7～8倍。

To solve the technical problem like large loss of fruit by picking machine and picking low efficiency, according to the natural characteristics of wolfberry mature fruit, the author designed a lyceum picking machine of simulate hand. The surface of the two rotating set up several relatively salient plastic rings in the hand-picking head. The two rotating body carry on relative motion to realize the simulation hand-picking to pick fruit by the direct current machine transmission. The machine performance test result showed that the quality of the hand-picking head was approximately 300 grams, the rotational speed of the direct current was 120 r/min, it moved steadily, there is no harm to leaves and immature fruit when it picked wolfberry fruit, and did not affect the yield and growth of postharvest. It could pick mature wolfberry 15 to 20 kg/h , however manual picking efficiency was only 2 to 3 kg/h. The machine can meet the need of large picking wolfberry,and its speed is 7 to 8 times that of manual picking.
