At present the total area of our country’s tea plantation reached nearly 4 millions of acres, with people's living standards improved, every year increased speed nearly 10%, tea consumption accelerated fastly, tea garden area has steadily expanded, tea total output hit a new high, tea industry is gradually growing, whole society pays close attention for it.The prevalence of tea science and technology in application of automation, standardization of tea garden low proportion, the most important is mechanical equipment is backward, the problem such as extensive of tea garden management.At the same time as the amount of labor transfer, production of tea planting, management facing many weak links, low efficiency, high cost of manual work.In order to make the mechanization of tea production, therefore Jiangsu Yunma agricultural machinery co.,ltd and Nanjing Agricultural Mechanization Research Institute jointly developed the first domestic ride type full automatic picking machine, has tested at tea garden in Jiangsu province, and got the success.The research and development of type 4CJ-20 ride self-propelled picking machine adopts a reciprocating cutting type cambered picker, and tea tree top surface is adapted to a height adjustable, picking, the picking width is 1.2 meters, the blade double action.Operation by a reciprocating cutting blade will cut tooth tip of tea, the fan leaf collecting device will be picking leaves into a leaf bag, efficiency is 3-8 mu / h.This machine, successfully resolved the lift type tea picking machine need to bear man, big labor intensity, the consumption problem.In the demo scene got the consistent high praise of experts, leaders,and the user's: This machine is a high degree of automation, stable performance, good in operation effect, domestic initiative, advanced and practical, and can save a lot of labor, laid a solid foundation for the tea mechanization production .
