chopping mechanism
解釋
切碎裝置-
The testing results of straw cutting and field experiment show that this mechanism has excellent anti - blocking capability. ( 2 ) a new no - till planter equipped with the strip chopping anti - blocking mechanism was developed. compared with other no - till planters, it possesses higher anti - blocking capability and suits the need of seeding in huabei plain where the winter wheat - summer corn continuous double cropping system gives much straw and short planting season
（ 2 ）研製出新一代玉米免耕播種機，配以新型防堵機構，防堵性能優越，連續三年分別對三代樣機進行的田間試驗表明，可在地表整稈覆蓋量10t / ha的條件下連續作業而不堵塞，該播種機的防堵性能好。 -
In this thesis, a new strip chopping anti - blocking mechanism and a new no - till planter operating well in heavy straw mulching condition are developed from the following aspects : ( 1 ) in order to solve the problem that the no - till planters can not work well when the mulched straw is long and thick, especially in the double cropping area of huabei plain where the winter wheat gives a high yield, a new strip chopping anti - blocking mechanism was developed. it consists of a group of rotary blades, a narrow tine opener, a shear bar, a hood and a deflector
在以下幾個方面進行了較為深入的研究： （ 1 ）在對國內外免耕播種機防堵裝置研究的基礎上，針對華北一年兩熟地區麥收后地表覆蓋量大的特點，通過對驅動式和從動式防堵裝置的對比實驗，設計出一種具有高效防堵能力的帶狀粉碎防堵裝置，該裝置由組合刀片、開溝器、定刀片、罩殼和導草扳組成。 -
Firstly, the basic theory of switch reluctance generator ( srg ) is discussed in detailed, based on the mechanism electric energy converting analysis, non - linear analysis and non - linear simulation. three control methods of srg ( angle position control method, current chopping control method, pulse width modulation control method ) are deeply studied and analyzed. the electronic controller, which controlled by dsp or by hardware circuit are developed for low - power switched reluctance generation system
