【摘要】：在葡萄种植过程中,施肥作业是极其重要的环节且繁重,大面积的葡萄施肥已实现机械化,施肥机械性能直接影响葡萄的产量与质量,因此葡萄施肥机性能检测已成为评价施肥机作业性能的重要一环,也将影响后期施肥机的设计与改进。为了解决目前国内施肥机排肥性能检测设备存在操作复杂、检测不准确等问题,针对宁夏地区大量使用的葡萄有机肥单行施肥机,本文设计了一种基于PLC精准控制的葡萄施肥机性能检测系统,实现准确地检测葡萄施肥机的排肥量、稳定性、均匀性和断条率。首先,采用SolidWorks设计了葡萄施肥机性能检测系统机械部分以及ANSYS对整体性能检测系统进行有限元分析,缩短了机具的设计时间;其次,使用AutoCAD Electrical软件设计了性能检测系统控制部分;然后,利用GX works编程软件编写了 PLC的梯形图运行语言;最后,运用组态王(King View)与PLC建立了串口通讯,完成了整个性能检测系统的实时监控。本文主要的研究工作如下:(1)结合拖拉机田间作业输出转速,设计了硬件部分的施肥机支架、输送带的带型、输送带支架和称重装置,确立了性能检测系统机械部分的构架和传动流程。(2)在硬件的设计基础上,通过上位机软件编写了 PLC控制梯形图和绘制组态监控画面。结合控制部分,完成了机械部分的操作。(3)通过以上设计,确立整体试验测试方案。葡萄施肥机性能检测系统可准确测出葡萄施肥机的排肥量、稳定性、均匀性和断条率是否达到国家标准。(4)设计了一种运行可靠、测量准确、智能高效的新型葡萄施肥机性能检测系统,用于葡萄有机肥单行施肥机性能的检测,满足葡萄施肥机性能检测的农业标准。控制变频电机输出转速和输送带带速,可模拟不同型号施肥机的实际工况,提高葡萄施肥机的排肥量、稳定性、均匀性和断条率等性能指标的精度和效率。
[Abstract]:In the process of grape planting, fertilization is an extremely important link and heavy, the large area of grape fertilization has been mechanized, the mechanical properties of fertilizer directly affect the yield and quality of grapes. Therefore, the performance testing of grape fertilization machine has become an important part of the evaluation of the performance of the fertilization machine. It will also affect the design and improvement of the later fertilization machine. In order to solve the problems of complex operation and inaccurate detection of fertilizer discharge performance testing equipment of domestic fertilization machine at present. Aiming at the grape organic fertilizer single-line fertilization machine which is widely used in Ningxia area, this paper designs a kind of performance testing system of grape fertilization machine based on PLC precision control, which can accurately detect the amount of grape fertilization machine. Stability, uniformity and breaking rate. Firstly, the mechanical part of the performance testing system of grape fertilization machine was designed by SolidWorks and the finite element analysis of the whole performance test system was carried out by ANSYS. The design time of machine and tools is shortened; Secondly, the control part of the performance testing system is designed by using AutoCAD Electrical software. Then, the trapezoidal diagram running language of PLC is written by using GX works programming software. Finally, the serial communication between KingView and PLC is established. The main research work in this paper is as follows: 1) combined with the output speed of tractor field operation, the hardware part of the fertilizer machine support, belt type of conveyor belt is designed. Conveyor belt support and weighing device, the mechanical part of the performance detection system frame and transmission flow. 2) on the basis of hardware design. The PLC control trapezoid diagram and drawing configuration monitoring picture are compiled by the upper computer software. Combined with the control part, the operation of the mechanical part is completed. Establish the whole test and test scheme. The performance test system of grape fertiliser can accurately measure the fertilizer discharge quantity, stability, uniformity and broken strip rate of grape fertilization machine to meet the national standard. 4) designed a reliable operation. Accurate measurement, intelligent and efficient performance testing system of a new type of grape fertilization machine, used for the performance testing of grape organic fertilizer single-line fertilization machine. The output speed of frequency conversion motor and the speed of conveyer belt can be controlled to simulate the actual working conditions of different types of fertilizing machine and to improve the quantity and stability of the fertiliser of grape. Accuracy and efficiency of performance indicators such as uniformity and broken bar rate.
