【摘要】：隨著城鎮(zhèn)道路建設(shè)面積不斷增加,道路綠化樹(shù)木成為城鎮(zhèn)道路綠化建設(shè)重要組成部分和城市文明的重要標(biāo)志,它能夠改善城鎮(zhèn)氣候、組織城鎮(zhèn)交通、改善環(huán)境衛(wèi)生、保護(hù)生態(tài)環(huán)境、豐富城鎮(zhèn)藝術(shù)形象。但是樹(shù)木生長(zhǎng)繁茂,容易受到病蟲(chóng)害的影響,所以需要定期進(jìn)行修剪、澆水、病蟲(chóng)害防治和剩余物處理等養(yǎng)護(hù)。道路綠化樹(shù)木養(yǎng)護(hù)是一項(xiàng)系統(tǒng)工作,以往依靠手工完成,工作困難、勞動(dòng)強(qiáng)度大、安全性低、機(jī)械化程度低。本文針對(duì)傳統(tǒng)道路綠化樹(shù)木養(yǎng)護(hù)困難、修剪剩余物不能及時(shí)有效回收利用造成資源浪費(fèi)等問(wèn)題,設(shè)計(jì)一種集修剪、削片、噴霧等多功能為一體的道路綠化樹(shù)木養(yǎng)護(hù)多功能機(jī),主要由汽車底盤、修剪系統(tǒng)、噴霧系統(tǒng)、削片系統(tǒng)等組成。通過(guò)對(duì)現(xiàn)有機(jī)型、設(shè)備及各工作裝置工作原理的研究,對(duì)六自由度修剪系統(tǒng)結(jié)構(gòu)、噴霧裝置結(jié)構(gòu)和液壓系統(tǒng)進(jìn)行設(shè)計(jì),對(duì)削片機(jī)進(jìn)行選型,采用汽車底盤發(fā)動(dòng)機(jī)作為動(dòng)力源,合理分配動(dòng)力傳動(dòng),完成修剪、削片、噴霧、行走等工作。運(yùn)用SolidWorks軟件對(duì)整機(jī)進(jìn)行建模和干涉檢查；對(duì)修剪系統(tǒng)進(jìn)行運(yùn)動(dòng)學(xué)、動(dòng)力學(xué)分析,對(duì)整機(jī)進(jìn)行側(cè)翻穩(wěn)定性分析；運(yùn)用ADAMS軟件對(duì)主體結(jié)構(gòu)修剪系統(tǒng)進(jìn)行ADAMS仿真分析,模擬修剪系統(tǒng)運(yùn)動(dòng)情況,得到各個(gè)關(guān)節(jié)的角度、角速度、角加速度、力和力矩的變化曲線、以及修剪刀具位置關(guān)系,結(jié)果分析表明設(shè)計(jì)達(dá)到要求,為結(jié)構(gòu)設(shè)計(jì)改進(jìn)提供指導(dǎo)；運(yùn)用ANSYS軟件對(duì)修剪系統(tǒng)和車架進(jìn)行靜力學(xué)與模態(tài)分析,得到應(yīng)力、應(yīng)變及模態(tài)振型云圖,比較分析數(shù)據(jù),修剪系統(tǒng)和車架的強(qiáng)度和剛度符合設(shè)計(jì)要求,且工作過(guò)程中不會(huì)發(fā)生共振現(xiàn)象。同時(shí),道路綠化樹(shù)木養(yǎng)護(hù)多功能機(jī)功能齊全,機(jī)械化程度高,具有很高的實(shí)際利用意義和經(jīng)濟(jì)效益。
[Abstract]:With the increasing area of urban road construction, road greening trees become an important part of urban road greening construction and an important symbol of urban civilization. It can improve urban climate, organize urban traffic, improve environmental hygiene. To protect the ecological environment and enrich the artistic image of towns. But trees grow luxuriantly and are susceptible to pests and diseases, so they need regular pruning, watering, pest control and residue treatment. The maintenance of road greening trees is a systematic work. In the past, it was done by hand, so it was difficult to work, the intensity of labor was high, the security was low, and the degree of mechanization was low. Aiming at the problems of difficult maintenance of traditional road greening trees and the waste of resources caused by the timely and effective recovery and utilization of pruning residues, a multifunctional maintenance machine for road greening trees is designed, which integrates pruning, slicing, spraying and so on. Mainly consists of automobile chassis, pruning system, spray system, cutting system and so on. Based on the study of the working principle of the existing models, equipments and working devices, the structure of the six-degree-of-freedom pruning system, the structure of the spray device and the hydraulic system are designed. The chippers are selected and the automobile chassis engine is used as the power source. Reasonable distribution of power transmission, complete pruning, cutting, spray, walking and so on. SolidWorks software is used to model the whole machine and interference check, kinematics and dynamics analysis to the pruning system, and roll stability analysis to the whole machine. ADAMS simulation analysis of the main structure pruning system is carried out by using ADAMS software. The angle, angular velocity, angular acceleration, force and torque of each joint are obtained by simulating the motion of the pruning system. The results show that the design meets the requirements and provides guidance for the improvement of the structure design. The static and modal analysis of the pruning system and frame is carried out by using ANSYS software, and the stress, strain and modal vibration pattern are obtained. The comparative analysis data show that the strength and stiffness of the pruning system and frame meet the design requirements. And the resonance will not occur in the working process. At the same time, the multifunctional maintenance machine for road greening trees has complete functions and high degree of mechanization, which has high practical significance and economic benefit.
