Example Embodiment
[0037] Example 1
[0038]1. Select about 500 mu of one-season rice fields in Gaoqiao Town, Changsha County, and sow milk vetch seeds among the rice rows 15 days before the rice harvest in the autumn of the previous year.
[0039] 2. After the rice is harvested, use a trencher to open ditches around the field. At the same time, open a straight ditch every 10m or so to form a "well"-shaped ditch system in the paddy field.
[0040] 3. In mid-March, clean up the "well"-shaped ditch system in the field to ensure the smooth flow of the drainage ditch, so that there will be no water left on the surface of the field when it is sunny, and no water will accumulate in the field when it rains.
[0041] 4. When the milk vetch seeds are about to mature from the end of April to the beginning of May, choose a full-feed rice combine harvester, and check the air volume of the rice combine harvester fan, the inclination angle of the upper sieve of the double-layer vibrating screen, the height an...
Example Embodiment
[0044] Example 2
[0045] 1. Select about 300 mu of one-season paddy field in Sanxianhu Town, Nan County, Dongting Lake District, and sow milk vetch seeds in the field 2-3 days after the rice harvest in the autumn of the previous year.
[0046] 2. Within half a month after the sowing of milk vetch, choose fine weather and use a trencher to open horizontal, vertical and side ditches in the rice fields.
[0047] 3. In mid-April, clean up the horizontal, vertical and side ditches in the field, so that the horizontal and vertical ditches and side ditches can all be drained smoothly, so that there is no water left on the surface of the field when it is sunny, and no water accumulates in the field when it rains.
[0048] 4. When the milk vetch seeds are about to mature in mid-May, choose a full-feed rice combine harvester, and check the fan air volume of the rice combine harvester, the inclination angle of the upper sieve of the double-layer vibrating screen, the height and speed of...

Abstract
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.
Description
technical field [0001] The invention relates to a method and a device for mechanically harvesting milk vetch seeds. Background technique [0002] Green manure is an important part of ecological agriculture and has played an important role in my country's agricultural production. Due to the rapid development of the chemical fertilizer industry and the transfer of rural labor forces, the green manure planting area has declined sharply in the past 30 years. In recent years, with the changes in the global economic situation, rising energy prices, increasing environmental protection requirements, and shortages of food and feed supplies, the restoration and development of green manure production has attracted the attention of the country, government and all walks of life. [0003] Milk vetch is the main green manure crop in southern paddy fields. Before the reform and opening up, the production and utilization of milk vetch played an important role in rice production and paddy s...
