| Abstract: |
| This paper deals with normal working conditions under which the sweep wings do not disturb the unploughed Land in the course of ploughing by the rotary double-wing sweep,and analyses the variations and affecting factors of respective moving parameters in the course of soil cutting from which the principles of selection of feature coefficient-λ=Rω/Ve were determined.This paper also illustrates geometry parameters,moving parameters and theoretical calculation formula of application of parameter as well as the scope of value-taking by means of actual examples as to provide bases for the designing of the sweep types. |
