The invention discloses a mechanical Chinese
milk vetch seed harvesting method and device. The method comprises the following steps: cleaning ditches and draining in a field; adjusting a harvester; cleaning sundries in the field; and harvesting the Chinese
milk vetch in the field. The device comprises a fan, a double-
deck vibrating screen, a reel, a cutter, an
auger and a header, wherein the air quantity of a fan of a whole-feed rice combine is 6-9 m / s; the inclination angle of an upper screen of the double-
deck vibrating screen and a horizontal plane clamp form an angle of 3-5 degrees; the distance from reel teeth of the reel to the cutter does not exceed 15 cm; the rotation speed of the reel is 10-15 r / min; the inclination angle of the unisexual reel teeth on the reel tilts backwards and forms an included angle of 5-15 degrees with the perpendicular line; the distance between the cutter and the
auger does not exceed 15 cm; the cutter is 5 cm above the ground. According to the method and the device, the Chinese
milk vetch can be harvested by using the conventional harvester through
continuous testing and adjustment, the problem of
bottle neck of seed production in southern rice area
green manure crop production and utilization development is solved, a direct
promotion effect on
green manure development which is arisen in China again is achieved, and the incomes of Chinese milk vetch seed reserving farmers are improved; the method and the device have great application and promotion value.
