液压驱动前悬挂式果树修剪机的设计与试验

Design and Test of a Hydraulic Driven Front Suspension Pruning Machine for Fruit Trees

目前,果树修剪成本高且成效低问题,已经严重制约了果树种植行业的发展。为此,研发了全自动果树修剪机具,并在试验中对应用效果进行分析,以达到果树种植行业效率与产值双提升的目的。确定了全自动果树修剪机的工作原理与总体结构,并针对机具的关键部位进行了相关设计与理论分析。通过对修剪机总成支撑锯切作出合理分析,对修剪机支撑杆的位置以及清除机构的工作过程作出分析,确定圆锯片刀的齿数是120齿、尺寸是14in。对液压油缸的尺寸以及液压系统的合理性作出分析,确定修剪马达转速为1600r/min。进行修剪试验,结果表明:相关作业参数均符合设计要求,果树漏剪率为10%,符合修剪需求。

At present, the cost of the fruit tree is high and the effect is low. This problem has been restricted to the good development of the fruit tree planting industry. Therefore, a scientific full-automatic fruit tree pruning machine is developed, and its reasonable application is made in the experiment, so as to achieve the purpose of double promotion of the efficiency and the output value of the fruit tree planting industry. In this paper, the working principle and general structure of the full-automatic fruit tree trimmer are determined, and the relevant design and theoretical analysis are carried out for key parts of the implement. By reasonable analysis of the support and sawing of the trimming machine assembly, the position of the supporting rod of the trimmer and the working process of the cleaning mechanism are analyzed, the number of teeth of the circular saw blade cutter is determined to be 120 teeth, and the ruler 14 inches. Determine the rationality of relevant design, analyze the size of hydraulic cylinder and rationality of hydraulic system, and trim motor speed is 1600 r/min. Finally, the full-automatic tools are used to carry out the trimming test to make trial production, commissioning, assembly and relevant working parameters of fruit tree contour trimming machines and tools meet the design requirements. Meanwhile, the pruning rate of fruit trees is 10%, which also meet the requirement of trimming.
