Problems solved by technology

[0003] Existing harvesters cannot keep the height of stubble cut at a certain level when harvesting the first season of ratooned rice, which is easy to damage the ratooned rice and affect the yield of ratooned rice in the next season; when the existing harvester harvests the first stubble of ratooned rice, most of the rice stalks enter The threshing system, the power consumption of the threshing system is relatively large, the length of the stems discharged after threshing is relatively large, and cannot fall to the ground, and it is easy to accumulate on the surface of the stubble of the ratooned rice, affecting the regrowth of the ratooned rice and having a significant impact on the yield of the ratooned rice. influences

Embodiment 1

[0029] Such as figure 1 As shown, a regenerative rice harvesting header includes an upper header 1, a lower cutter driving device 6, an ear head height detection device 10, a stubble height detection device 7 and a hydraulic cylinder control system 3. The upper header 1 is fixedly connected to the conveying trough 2, the hydraulic cylinder control system 3 is installed on the conveying trough 2, the lower end of the conveying trough 2 is hinged with one end of the conveying trough hydraulic cylinder 5, and the other end of the conveying trough hydraulic cylinder 5 is connected to the harvester frame 4 hinged. The bottom of the upper header 1 is hinged with the lower cutter driving device 6, and the lower cutter driver 6 is located behind the upper cutter 9 along the advance direction of the harvester. Stubble height detection device 7 is installed. Ear head height detection device 10 is installed on the reel frame. Delivery trough hydraulic cylinder 5, lower cutter driving ...

Abstract

The invention provides a combine harvester and a ratoon rice harvesting header. The ratoon rice harvesting header comprises an upper-layer header, a lower cutter driving device, an ear height detection device, a stubble height detection device and a hydraulic cylinder control system. The ear height detection device and the stubble height detection device can collect information of ears and stubbles in real time and send the same to the hydraulic cylinder control system for processing, and cutting height of an upper cutter and a lower cutter can be adjusted in real time to maintain positions ofthe stubbles and the ears to be fixed. Height of the ears fed into the harvester can be maintained stable, burden of a threshing and cleaning system can be reduced, and damage to the ears can be prevented; height of the stubbles can be maintained fixed to meet growth needs of regeneration crops. In addition, the lower cutter can be protected from being damaged.

Description

technical field [0001] The invention relates to the field of combine harvester headers in agricultural machinery, in particular to a harvesting header suitable for harvesting regenerated rice head stubble and regenerated stubble, and capable of automatically controlling the height of the ear head and the height of the remaining stubble. Background technique [0002] Raising rice is a mode of rice planting, which is characterized in that after a crop of rice matures, only about 2 / 3 of the upper part of the rice plant is cut off, and the rice ears are harvested, leaving the lower 1 / 3 of the plant and root system for fertilization and cultivation , let it grow another season of rice. [0003] Existing harvesters cannot keep the height of stubble cut at a certain level when harvesting the first season of ratooned rice, which is easy to damage the ratooned rice and affect the yield of ratooned rice in the next season; when the existing harvester harvests the first stubble of rato...
