Straw cleaning device for drip irrigation corn no-tillage sowing strip

The invention relates to a drip irrigation corn no-tillage sowing strip straw cleaning device. The device comprises a front double-side spiral grass pulling mechanism, a drip irrigation strip ditching and laying mechanism, a back-pulling single-inner-side spiral grass pulling mechanism, a rear single-outer-side spiral grass pulling mechanism and a rack. The front double-side spiral grass pulling mechanism is used for cutting straw in a narrow-row drip irrigation zone laying area and throwing the straw to the two sides of the narrow-row drip irrigation zone laying area; the drip irrigation tape ditching and laying mechanism is used for ditching a drip irrigation tape laying ditch in the clean area cleaned by the front double-side spiral grass pulling mechanism and laying a drip irrigation tape; the two groups of back-poking single-inner-side spiral grass poking mechanisms which are in axial symmetry about the longitudinal axis of the machine are used for cutting straws in the seeding strips after the drip irri
