【摘要】：隨著社會經(jīng)濟的發(fā)展,傳統(tǒng)的煤、石油、天然氣等化石燃料已經(jīng)無法滿足人類發(fā)展的需求,為了避免能源危機和環(huán)境污染,需大力開發(fā)可再生的清潔能源。巨菌草作為一種新的生物能源,能用來代替木本植物制作食用菌的培養(yǎng)基、喂養(yǎng)牲畜和制造沼氣等。其莖稈粗壯、根系發(fā)達、直立生長,富含糖分和蛋白質(zhì),同時也是一種新型高效的經(jīng)濟作物。隨著巨菌草的引入及大面積種植,如何合理的收獲巨菌草成為首要解決的問題。現(xiàn)階段因地形和收獲方式不同,巨菌草收獲機分為大小兩種機型。大型的巨菌草收獲機大致可分為全機械化和半機械化兩大類,半機械化收獲機由兩臺用于收割和剝?nèi)~的機器構(gòu)成,人工輔助喂入、打捆、清理等工序。全機械化是用聯(lián)合收獲機完成收割、剝?nèi)~、打捆、清理等全部工序。但大型巨菌草收獲機因地形限制,適合在平地收獲,若在坡地收獲機器易損壞,巨菌草破頭率增加,且大型收獲機在坡地中難于操作,靈活性差;而現(xiàn)有的小型巨菌草收獲機功能單一,效率低下。據(jù)此擬研究一種可適應(yīng)山地收割且操作性靈活的小型巨菌草收獲機。研究的小型巨菌草收獲機所要實現(xiàn)的功能是將巨菌草收割、打捆,此收獲機主要設(shè)計內(nèi)容是根據(jù)地面仿形設(shè)計出集收割、打捆的割捆工作裝置。設(shè)計割捆工作裝置時,先了解巨菌草的生物力學性質(zhì)和現(xiàn)有收獲機械的特點,提出用虛擬樣機技術(shù)設(shè)計工作裝置。先是使用三維軟件SolidWorks對工作裝置進行模型設(shè)計并裝配,再用ANSYS軟件分析割捆機重要零部件的力學性能,為理論設(shè)計提供基礎(chǔ),最后通過ADAMS軟件對設(shè)計的工作裝置進行仿真分析,驗證機構(gòu)的運動合理性,確定割捆裝置的關(guān)鍵結(jié)構(gòu)尺寸,做為物理樣機的基礎(chǔ)。對巨菌草小型割捆機的工作裝置的設(shè)計改進,不僅提高了機子的操作靈活性,也增強了對巨菌草的收割效率;能減少勞動力投入,增加農(nóng)民的經(jīng)濟收入。
[Abstract]:With the development of social economy, traditional fossil fuels such as coal, oil and natural gas can not meet the needs of human development. In order to avoid energy crisis and environmental pollution, it is necessary to develop renewable clean energy. As a new bioenergy source, Giant Grass can be used to replace woody plants to produce edible fungi, feed livestock and produce biogas, etc. Its stem is strong, its root system is developed, erect growth, rich in sugar and protein, but also a new efficient cash crop. With the introduction of megalomycetes and planting in large areas, how to harvest megalomycetes rationally becomes the most important problem. At present, due to the different terrain and harvest methods, the megalomonas harvester can be divided into two types: size and size. The large megalomonas harvester can be divided into two categories: fully mechanized and semi-mechanized. The semi-mechanized harvester is composed of two machines used for harvesting and leaf-stripping, and manual auxiliary feeding, bundling, cleaning and so on. Full mechanization is the use of combine harvesters to complete harvesting, leaf stripping, bundling, cleaning and other processes. However, because of the terrain limitation, the large megalobium harvester is suitable for harvesting in the flat land. If the harvesting machine is easy to be damaged in the sloping land, the rate of breaking the head of the giant fungus grass increases, and the large-scale harvester is difficult to operate in the sloping land, and the flexibility is not good. The existing megalomycetes harvester has a single function and low efficiency. Based on this, a small megalobium harvester, which can adapt to mountain harvesting and operate flexibly, is studied. The function of the study is to harvest and bundle the giant fungus and grass. The main design content of the harvester is to design the work device of harvesting and bundling according to the ground copying. The biomechanical properties of the giant fungus and the characteristics of the existing harvesting machinery were first understood in the design of the cutting and baling working device, and the virtual prototype technology was used to design the working device. First, the model of the working device is designed and assembled by using the three-dimensional software SolidWorks, then the mechanical properties of the important parts of the shearer are analyzed by using the ANSYS software, which provides the basis for the theoretical design. Finally, the designed working device is simulated and analyzed through the ADAMS software. To verify the rationality of the movement of the mechanism and determine the key structural dimensions of the cutting and binding device as the basis of the physical prototype. The design and improvement of the working device of the megalomycetes cutting and baling machine not only improves the operating flexibility of the machine, but also enhances the harvesting efficiency of the giant fungus grass, which can reduce the labor input and increase the farmers' economic income.
