【摘要】：當(dāng)前,我國政府對農(nóng)業(yè)機(jī)械化高度重視,對農(nóng)業(yè)投入的不斷增加,長沙縣農(nóng)業(yè)機(jī)械化水平得到了快速的發(fā)展,總體水平達(dá)到了歷史最好水平,促進(jìn)了長沙縣的農(nóng)業(yè)經(jīng)濟(jì)的發(fā)展,也很大程度上將農(nóng)民從繁重的體力勞動中解放出來。本研究是在分析國內(nèi)外收割機(jī)的研究現(xiàn)狀和調(diào)查長沙縣收割機(jī)推廣的機(jī)型、推廣的數(shù)量、購機(jī)補(bǔ)貼情況等的基礎(chǔ)上,對整個推廣的情況有一個具體的了解,在這個過程中發(fā)現(xiàn)長沙縣收割機(jī)推廣過程中存在的問題與不足,包括：自然條件問題、收割機(jī)的投入成本高,利用率低、農(nóng)業(yè)基礎(chǔ)設(shè)施不能滿足收割機(jī)的工作條件、售后服務(wù)跟不上、推廣經(jīng)費(fèi)不足、宣傳力度不夠,認(rèn)識不足、管理和培訓(xùn)體系滯后等七個方面：對存在的問題提出了對策和建議,包括：加快農(nóng)田的基本設(shè)施建設(shè),推行糧田適度規(guī)模經(jīng)營、提高利用率、增大作業(yè)量、加大科研能力,提高產(chǎn)品質(zhì)量,降低產(chǎn)品價格等七個方面,希望這些措施和建議對長沙縣收割機(jī)的推廣具有一定的參考作用。運(yùn)用模糊評判法對長沙縣收割機(jī)進(jìn)行了選型。根據(jù)水稻聯(lián)合收割機(jī)的選型原則,確定選型的主要影響因素,包括作業(yè)性、經(jīng)濟(jì)性、通過性、適應(yīng)性、可持續(xù)性、可維修性、安全性等,并根據(jù)專家評判意見,進(jìn)行權(quán)重的確定,得出評判矩陣,最后得出評判結(jié)果,即收割機(jī)優(yōu)劣的排列順序。得出的結(jié)論認(rèn)為,對于長沙縣連片的稻田,可以選用井關(guān)4LBZ-145C、洋馬4LBZJ-140D(AG600)、久保田4LZ-2.5CPRO688Q)收割機(jī)。對于小片的稻田,可以選用國產(chǎn)的中天龍舟4LZ-2.2、福田雷沃4LZ-1.8收割機(jī)。在運(yùn)用模糊評判法結(jié)果的基礎(chǔ)上,對長沙縣收割機(jī)進(jìn)行了優(yōu)化配置。采用非線性規(guī)劃配備法,以每年的作業(yè)成本最低為目標(biāo)函數(shù),作業(yè)量,作業(yè)時間,機(jī)型數(shù)量,非負(fù)整數(shù)為約束條件,建立了長沙縣水稻收割機(jī)優(yōu)化配置的一般模型,運(yùn)用MATLAB進(jìn)行求解,得到了長沙縣收割機(jī)的優(yōu)化配置方案,對現(xiàn)有的機(jī)型數(shù)量進(jìn)行調(diào)整,可以為長沙縣的收割機(jī)的配置提供科學(xué)依據(jù)。
[Abstract]:At present, the Chinese government attaches great importance to agricultural mechanization, and with the increasing investment in agriculture, the level of agricultural mechanization in Changsha County has developed rapidly, and the overall level has reached the best level in history, which has promoted the development of agricultural economy in Changsha County. To a large extent, farmers are also liberated from heavy physical labor. This study is based on the analysis of the current research situation of the harvesters at home and abroad and the investigation of the models popularized by the harvesters in Changsha County, the quantity popularized, the subsidy situation of purchasing machines, etc., and has a specific understanding of the whole popularization situation. In this process, the problems and shortcomings in the popularization of the harvester in Changsha County are found, including: natural conditions, high input cost of harvester, low utilization rate, and agricultural infrastructure can not meet the working conditions of the harvester. The after-sales service can not keep up with, the promotion funds are insufficient, the propaganda is not enough, the understanding is insufficient, the management and training system lags behind, and so on seven aspects: put forward the countermeasure and suggestion to the existing problems, including: speeding up the construction of the farmland basic facilities, Seven aspects, such as promoting moderate scale operation of grain fields, increasing the utilization rate, increasing the amount of work done, increasing the scientific research capacity, improving the quality of products, and lowering the prices of products, It is hoped that these measures and suggestions will be helpful to the popularization of the harvester in Changsha County. The fuzzy evaluation method is used to select the harvester in Changsha County. According to the selection principle of rice combine harvester, the main influencing factors, including operation, economy, adaptability, sustainability, maintainability, safety and so on, are determined. The weight is determined, the judgment matrix is obtained, and the final judgment result is obtained, that is, the order of the advantages and disadvantages of the harvester. It is concluded that for the rice fields in Changsha County, 4LBZ-145C, 4LBZJ-140DA600 and 4LZ-2.5CPRO688Q) can be selected. For small paddy fields, the domestic Zhongtian Dragon Boat 4 LZ-2.2 and Fukuda Revo 4LZ-1.8 Harvester can be selected. Based on the results of fuzzy evaluation method, the optimal configuration of harvesters in Changsha County was carried out. A general model for optimal allocation of rice harvesters in Changsha County was established by using the nonlinear programming method with the lowest cost of operation as the objective function, the amount of work done, the working time, the number of models and the number of non-negative integers as the constraint conditions. The optimal configuration scheme of the harvester in Changsha County is obtained by using MATLAB, and the quantity of the existing harvester is adjusted, which can provide scientific basis for the configuration of the harvester in Changsha County.
