Description

TECHNICAL FIELD

[0001] The present application belongs to the field of cross-belt combined harvesting of soybean and corn in a combined planting mode, and particularly relates to a combined header suitable for a soybean and corn combined planting mode. BACKGROUND

[0002] Due to the complexity of the soybean and corn belt-shaped combined planting technology, there is no mature machine type for the special machine tools required by the belt-shaped combined planting, and most of them are still in the performance optimization test stage of the prototype, and there is still a certain distance from the final industrial application. The mechanical types, adaptability, reliability and operation performance of the soybean and corn combined harvesting machine need to be further improved. At present, the soybean and corn belt-shaped combined planting harvesting machinery is mainly based on the transformation of the original corn harvesting machinery and soybean harvesting machinery. It is usually a separate harvesting method of different machines harvesting at different time periods or different machines harvesting at the same time period. The harvesting time is long, and the harvesting efficiency is low. The soybean and corn planted in the combined planting mode are harvested at one time, which improves the harvesting efficiency, reduces the purchase cost and labor cost, and realizes the cross-belt soybean-corn belt-shaped combined planting mode. The purpose of combined harvesting improves the land utilization rate and output rate, and has important scientific significance and practical value for promoting agricultural efficiency and increasing farmers' income.

[0003] At present, some experts and scholars have carried out relevant research on the harvesting of soybean and corn. Chinese patent CN115735568A discloses a corn and soybean belt-shaped combined planting mechanized combined harvesting method, which is based on the planting mode of corn and soybean, and analyzes the structure and layout of the harvesting machinery. It proposes a soybean and corn planting mode and a harvesting structure layout of the harvesting machinery, which provides a way for corn and soybean belt-shaped combined planting mechanized combined harvesting. Chinese patent CN115191217A discloses a soybean and corn synchronous combined harvesting machine and its working method, which provides a soybean and corn synchronous combined harvesting machine that can complete corn harvesting while completing soybean harvesting.

[0004] While the aforementioned inventions can accomplish soybean and corn harvesting under specific conditions, certain problems remain. It's difficult to ensure that all corn plants are planted in a straight line, requiring the harvester to constantly adjust its cutting position to ensure complete harvesting of both soybeans and corn. Furthermore, environmental factors can cause corn and soybean plants to tilt or lodging, necessitating lower cutting positions to guarantee complete harvesting. Additionally, soybean-corn intercropping patterns vary across regions. Due to differences in sunlight, wind, and water conditions, planting spacing between soybeans and corn is adjusted, often using different ridge heights. When the machine height is too low, the harvester's structure may "eat the ridge," leading to uneven stress, structural deformation, and machine deviation over time. These issues place higher demands on harvesting machinery used in soybean-corn intercropping systems. Summary of the Invention

[0005] To address the above problems, this invention designs a combined harvesting platform and harvester for soybean-corn intercropping, which can realize the longitudinal movement of the corn and soybean cutting and harvesting devices and adjust the height and angle of the corn and soybean cutting and harvesting devices. It can adapt to soybean and corn planting with different ridge heights and spacings for harvesting, thereby improving the soybean and corn harvesting rate and the applicability of the machinery.

When there are a large number of inclined and prostrate corn plants, the corn structure angle adjusting screw rod 805 under the corn angle adjusting frame 808 can be adjusted to make the corn sweeping and harvesting device 1 obtain a lower supporting height and a lower cutting height, so that the harvesting rate of the corn sweeping and harvesting device 1 on the inclined and prostrate corn plants can be improved. When the planting distance and the ridge height of the soybean and corn are different, the inner end adjusting screw 806 and the outer end adjusting screw 810 can be adjusted to adjust the distance between the corn sweeping and harvesting device 1 and the soybean sweeping and harvesting device 9, and the soybean structure angle adjusting screw rod 804 under the soybean angle adjusting frame 807 and the corn structure angle adjusting screw rod 805 under the corn angle adjusting frame 808 can be adjusted to adjust the height position of the corn sweeping and harvesting device 1 and the soybean sweeping and harvesting device 9, so that different longitudinal positions and distances, ridge heights, and harvesting cutting heights of the two harvesting devices can be obtained, and the harvesting of the inclined and prostrate plants in different longitudinal positions and distances of the soybean and corn rows can be met. Since the two harvesting devices can be adjusted, the phenomenon of "eating the ridge" can be avoided.
