玉米秸稈粉碎還田機(jī)的設(shè)計(jì)含7張CAD圖,玉米,秸稈,粉碎,還田,設(shè)計(jì),cad 玉米秸稈粉碎還田機(jī)設(shè)計(jì) 摘要 近幾年隨著玉米產(chǎn)量的大幅度的提高，秸稈、根茬也大量增多，隨之出現(xiàn)的問(wèn)題是清理秸稈、刨根茬，成了農(nóng)民種地前最頭痛的事，為爭(zhēng)時(shí)爭(zhēng)工，不影響秋種的進(jìn)度，有些農(nóng)民只好將秸稈就地焚燒。既浪費(fèi)資源又污染環(huán)境。可以把秸稈粉碎后鋪撒在地里，既環(huán)保又可以改變土壤的理化性。玉米秸稈粉碎還田機(jī)就是這樣的一種農(nóng)具，本設(shè)計(jì)采用均力免震法排列刀，工作時(shí)由拖拉機(jī)采用后懸掛方式進(jìn)行耕作。刀具使用Y型刀中間采用齒輪傳動(dòng)和皮帶傳動(dòng)相結(jié)合的方法。 關(guān)鍵詞 還田機(jī) 玉米 設(shè)計(jì) Design of the Corn straw counters-field Abstract In recent years with the corn yield significant enhancement of straw, root, the increasing number of crop also. The resulting problems is clean up straw, follow chi, became farmers sow the land before headaches. As for work, when does not affect to prepare for the progress of the straw stalk, some farmers had to local burned. Do so just a waste of resources and environmental pollution. We can put it to pieces after the stalks strewn in the field, the environmental protection can alter the soil physicochemical. Corn straw chopper drive is one such farm implements. This design uses shock-free laws are arranged in knife edge, the work by the tractor by way of farming after the suspension. Tool use Y knife among USES the gear transmission and the method of combining the belt transmission.
