夏季酿酒葡萄修剪机的设计与试验

Design of Summer Wine Grape Pruning Machine

针对夏季酿酒葡萄修剪工作劳动强度大、效率低、修剪质量难以保证等问题,结合新疆酿酒葡萄种植模式,研制了一种夏季酿酒葡萄修剪机。首先对整机结构、工作原理、关键部件设计进行说明,然后运用Box-Benhnken中心组合试验方法对试验因素进行分析,以刀具转速、作业速度、含水率进行试验并进行响应曲面分析,建立曲面响应三维模型,并最终得出最优工作参数组合。试验结果表明:当作业速度1.5m/s、刀具转速1 200r/min、含水率65%时,切断率达到最大为96%。该机具作业性能可靠,各项指标满足性能设计要求。

In view of the problems of high labor intensity, low efficiency and difficult to guarantee the pruning quality of wine grapes in summer, a pruning machine for wine grapes in summer was developed based on the cultivation mode of wine grapes in Xinjiang. Firstly, the structure, working principle and the design of key components of the machine are described. Then, the Box-Benhnken central combination test method is used to analyze the test factors. The tool speed, working speed and moisture content are used to test and analyze the response surface, and the three-dimensional model of surface response is established, and the optimal combination of working parameters is obtained. According to the test results, when the operating speed is 1.5 m/s, the tool speed is 1200 r/min and the moisture content is 65%, the cutting rate reaches 96%. The performance of the machine is reliable, and the indexes meet the design requirements.
