Pruning is an important link in the growth of the grape industry,however the traditional pruning whichby pruning dominated has low productivity, Cutting machine can be used for large vineyard has no space forthe development in China’s cropping patterns, thus affecting the market competitiveness of the grape industry.Combined with the characteristics of cropping patterns vineyards in Xinjiang, this paper designs areciprocating vines pruning machine, which solve the problems of the long time-consuming, high labor costs,large operating, enhanced the competitive advantage of the grape industry.In this paper, the overall design of the reciprocating grape pruning machine mainly consists of frame,cutting system, drive mechanism of cutting knife, hydraulic system and profiling mechanism etc. Bycomparing the advantages and disadvantages of the cutter, the applicable scope of the transmission systemand the degree of difficulty of profiling mechanism to achieve, it is concluded that the optimal combinationscheme, and has carried on the SolidWorks3D modeling. Analysis the movement of cutter, velocity, stressand cutter balance of inertia force, through the MATLAB software to optimize the parameters of the cutter.The structure analysis of profiling mechanism Analyzed by ANSYS software, show the stress and straincontours of static analysis, calculating the stress concentration and the maximum deformation position ofthe profiling mechanism; and the modal shapes of dynamic analysis of the profiling mechanism, calculatingthe safety working frequency range. According to the parameters of cutter and agricultural powermachinery, select the appropriate hydraulic pump, hydraulic motor, hydraulic cylinder and oil tank, anddesigned a hydraulic principle diagram. Establish a cutter test bed, through cutting test of grape stem, withthe orthogonal experiment results show the optimal parameters of the test of pruning for: walking speed0.8m/s, the speed of500r/min and a moisture content of28.7%.Reciprocating vines pruning machine is mainly used in the vineyards of small spacing, according to thesize of the line spacing can realize the amplitude by automatic adjustment; can complete the function ofpruning and shaping. Reciprocating cutting machine not only can be used for the pruning of the vineyard, canalso be used for other pruning and shaping of orchards and gardens, has the very good social benefit andeconomic benefit, can get a big promotion.
