割稈刀 的英文怎麼說
中文拼音 [gēgǎndāo]
割稈刀
英文
stalk cutter-
It still works well when the mulched straw is more then lot / ha. ( 3 ) an experiment was conducted on a self - made testing equipment to investigate the chopping properties of wheat straw under different conditions. on the basis of testing results, main cutting curves of wheat straw were given under different cutting speeds of rotary blade, with different straw lengths, different moisture contents, different cutting position, different thick of knife edge, with and without shear bar
（ 3 ）為了研究帶狀粉碎防堵裝置對麥秸的切碎效果，在特製的實驗臺上，應用了虛擬儀器測試技術對不同處理的麥稈進行了切斷試驗，得到了在不同切割速度下對不同長度、不同含水率的麥稈、麥稈的不同切割部位以及有定刀和無定刀情況下的切斷率，為麥秸粉碎裝置的設計提供了依據。After this they continued for some long time in a reverie, as they went on seizing the ears of corn, drawing out the straw, gathering it under their arms, and cutting off the ears with their bill - hooks, nothing sounding in the barn but the swish of the straw and the crunch of the hook
說完這話以後，她們好長時間沒有說話，保持著沉默。她們繼續幹活，把麥穗從麥稈里理出來，夾在胳膊下，用鐮刀把麥穗割下來，在麥倉里，除了麥稈的沙沙聲和鐮刀割麥穗的聲音，聽不見別的聲音。The curves showed that the moisture contents of straw and the shear bar are the main factors impacting the cutting ratio besides cutting speed. the speed of 40mm / s is necessary to cut off wet straw. ( 4 ) the testing results indicate that the rotary speed of the blade axle need to be more then 1230 rpm ( rotary radius of the blade is 25cm ) to cut off straw ( with moisture content less then 20 % )
試驗結果表明，對于乾的長秸稈，刀片切割速度達到15m / s時，切斷率達100 ；對于乾的短秸稈，刀片切割速度需達到20m / m / s以上；要切斷濕秸稈需要有40m / s以上的切割線速度；加定刀與不加定刀對于切斷麥秸這類軟質秸稈是非常重要的，其切斷速度差別很大；另外，麥秸不同部位所需要的切斷速度也是不一樣的，根部較之頂部和中部更難切斷。
