Abstract: An electric-drive circular-cutting and middle-placing windrower for oilseed rape is designed. Circular cutter adopts the cutting method that a chain-driven movable blade is combined with upper and lower double fixed blades, and designs a double-support circular cutter as well. Moreover, the symmetrical hugging and middle-placing reeling device is designed through artificial reeling operation. The simulated and kinematic analysis of the reeling device is done as well. The simulated analysis results show that the reeling track meets the operation requirement and the reeling devices have a good effect on the rape plants. The intelligent synchronous reeling control is designed on the reeling device drive. The field test of the prototype showed that the placing angle of the windrower was 11.48°, and the angle difference was 6.64°.This research provides theoretical and technical references for the design of the circular-cutting and middle-placing windrower for oilseed rape.

Keywords: circular cutting; symmetrical hugging; intelligent synchronous control; oilseed rape; cut and windrow.
