车载绿篱修剪机设计含三维图+二维图+说明书

摘要

本次设计针对设计的是一种车载式绿篱修剪机的整机机械结构设计以及液压驱动系统设计，针对市场现有产品分析得出，现如今产品大多数耗能比较大，因为采用电机等机械结构驱动，导致了成本的增加，同时，因为自由度较多，机械传动效率相对较低，导致了整体灵活性较差，本文针对现存在的问题设计出一种新型的液压泵站驱动的车载式绿篱修剪机。
本文设计的车载绿篱修剪机具有体积小、智能化程度高、修剪能力强、液压驱动方便快捷等优势，相对于市场现有产品来说，解决了成本的同时，还能更好的适用大范围的修剪作业，具有现实的意义。采用独立的液压控制系统，控制三个油缸控制大臂俯仰系统、小臂伸缩系统和修剪摆动系统进行动作，同时液压系统中设立一个独立的驱动马达控制底座旋转，通过PLC编程，设定好程序，根据传感器的数据反馈，控制器驱动执行机构动作，实现了智能化；相对于传统的整体采用电机和机械结构驱动车载式绿篱修剪机来说，本文采用液压驱动传动，使得驱动力更大，更高效，效率更高，修剪能力更强；设置修剪组件单独控制，采用电机控制。对于整机位置定位采用液压油缸和马达控制，对于修剪组件采用电机控制，这样能更好的分配效率，使得较大的机械传动实现起来较低的部位用液压高效控制，修剪组件中修剪需要高速旋转，旋转需要稳定，采用一定功率的电机单独控制，可以避免设置整个液压系统中收到其他支路干扰影响修剪的稳定性。
本课题主要进行了如下设计：车载式绿篱修剪机的整体结构设计，关键部件的参数计算，关键轴的校核，液压系统原理图的设计、液压系统参数的计算、液压元件的选型、能量损失验算、热平衡验算、油缸的设计等。这种车载式绿篱修剪机的全新设计、全新优化是市场急需的，对于现如今城市园林修剪作业日益剧增的需求的一个现实的研发支持。市场需求的增加、技术研发的迫切需求使得这种车载式绿篱修剪机的设计有着广阔的前景。

ABSTRACT

The graduation design for the design is a kind of vehicle-based hedge trimmer mechanical structure design and hydraulic drive system design, in view of the market analysis of existing products, most of the current product energy consumption is relatively large, because of the use of mechanical structures such as motor drive, resulting in an increase in costs, and because of greater degrees of freedom, mechanical transmission efficiency is relatively low, resulting in poor overall flexibility, aiming at the existing problems, a new type of vehicle-mounted hedge trimmer driven by hydraulic pump station is designed in this paper.
The vehicle-mounted hedge trimmer designed in this paper has the advantages of small volume, high intelligence, strong trimming ability, convenient and fast hydraulic drive, etc. , it can also be better applied to a wide range of pruning operations, with practical significance. Using an independent hydraulic control system, control of three oil cylinder control arm pitching system, arm telescopic system and pruning swing system action, at the same time, an independent drive motor is set up in the hydraulic system to control the base rotation. The program is programmed by PLC. Compared with the traditional whole use of motor and mechanical structure to drive the vehicle-mounted hedge trimmer, this paper uses hydraulic drive drive, making the drive force larger, more efficient, more efficient, more powerful pruning capacity; Set up the pruning module to control alone, using motor control. For the position of the whole machine using hydraulic cylinder and motor control, for the trim components using motor control, so that a better distribution of efficiency, so that a larger mechanical transmission to achieve a lower part of the hydraulic efficient control, high speed rotation and stable rotation are needed in the pruning module, and a certain power motor can be used to control the pruning, which can avoid the interference of other branches in the whole hydraulic system.
This topic has carried on the following design mainly: the vehicle type green hedge trimmer overall structure design, the key component parameter computation, the key axis check, design of hydraulic system schematic diagram, calculation of hydraulic system parameters, selection of hydraulic components, check of energy loss, check of heat balance, design of cylinder, etc. . The new design and optimization of this kind of car-mounted hedge trimmer is urgently needed by the market. It is a realistic research and development support for the increasing demand of urban garden trimming. The increasing market demand and the urgent demand of technology research and development make the design of this kind of vehicle-mounted hedge trimmer have broad prospects.
