【摘要】：為南方小面積田塊棉稈切碎還田機(jī)設(shè)計了棉稈切碎還田裝置。該裝置由切割裝置、扶稈裝置、除茬裝置組成,棉稈由扶稈裝置喂入,從上至下依次被切斷、除茬。將該裝置掛接在土槽試驗(yàn)機(jī)上,對影響棉稈切割長度合格率、功耗和除茬率的主要因素,即機(jī)具前進(jìn)速度、鋸盤轉(zhuǎn)速和導(dǎo)向槽口寬度進(jìn)行了單因素試驗(yàn)和回歸正交試驗(yàn)。結(jié)果表明:影響合格率與除茬率的因素大小依次為機(jī)具前進(jìn)速度、鋸盤轉(zhuǎn)速、導(dǎo)向槽口寬度;影響功耗的因素大小依次是鋸盤轉(zhuǎn)速、機(jī)具前進(jìn)速度、導(dǎo)向槽口寬度。利用規(guī)劃求解進(jìn)行參數(shù)優(yōu)化,在棉桿長度合格率與除茬率分別不低于85%和90%的情況下,鋸盤轉(zhuǎn)速為860 r/min,機(jī)具前進(jìn)速度為0.65 m/s,導(dǎo)向槽口寬度為60 mm時,功耗為5.91 k W。
[Abstract]:A cotton stalk shredding and returning device was designed for a small area cotton stalk shredder in southern China. The device consists of a cutting device, a culm support device and a stubble device. The cotton stalk is fed in by the culm support device, which is cut off from top to bottom, and stubble is removed. The device was hung on the soil groove testing machine. The single factor test and regression orthogonal test were carried out on the main factors affecting the cotton stalk cutting length qualification rate, power consumption and stubble removal rate, namely, the advance speed of the machine, the rotating speed of the saw plate and the width of the guide slot. The results show that the factors that affect the qualified rate and stubble rate are the speed of the machine and the speed of the saw plate, the width of the guide groove, and the factors affecting the power consumption are the speed of the saw plate, the speed of the machine and the width of the guide groove. The parameters were optimized by programming solution. When the cotton rod length qualified rate and stubble rate were more than 85% and 90%, respectively, the speed of saw plate was 860 r / min, the speed of machine was 0.65 m / s, the width of guide slot was 60 mm, the power consumption was 5.91 kW.
