  • Patent number: 12075727
    Abstract: The present disclosure provides a ratooning rice harvesting header and a harvester including the same. The ratooning rice harvesting header includes a multi-layer adjustable disc cutter, a header, and an ear cutter. The multi-layer adjustable disc cutter is mounted below the header and located below a rear portion of the ear cutter. The ear cutter is mounted at a front end of the header. The multi-layer adjustable disc cutter includes at least one group of multi-layer disc cutting assemblies. Each group of multi-layer disc cutting assemblies includes two multi-layer disc cutting assemblies. Each of the multi-layer disc cutting assemblies includes three layers of vertically arranged blades. The use of the multi-layer adjustable disc cutter in cooperation with the ear cutter can reduce the straw-grain ratio of the part cut from the crops to reduce the power consumption of the harvester.

  • Publication number: 20240215476
    Abstract: The present disclosure provides a high-efficiency and low-damage potato combine harvester, including a digging device, a conveyance and separation device, a separation and elevation reversing device, a potato collection box, and a control unit. The present disclosure can realize low-damage digging, high-efficiency conveyance, and high-performance potato-soil and potato-stem separation at a time, can effectively reduce a digging resistance in potato harvesting and prevent soil hilling and potato damaging phenomena, and improves conveyance and separation efficiencies for a potato-soil-stem mixture. The present disclosure makes the harvester more adaptable to different soil properties and potato varieties, allows an operator to better adjust working performance of the harvester, reduces a falling damage of potatoes due to a large falling height in box packaging, and meets requirements of high-efficiency combine harvesting of the potatoes.

  • Patent number: 12022768
    Abstract: The present disclosure provides a high-efficiency and low-damage potato combine harvester, including a digging device, a conveyance and separation device, a separation and elevation reversing device, a potato collection box, and a control unit. The digging device is provided at a front end of the potato combine harvester. The conveyance and separation device is provided behind the digging device, and configured to perform preliminary conveyance and separation on a potato-soil-stem mixture dug by the digging device. The separation and elevation reversing device is provided at a side of the conveyance and separation device, and configured to separate the potato-soil-stem mixture from the conveyance and separation device and elevate potatoes to the potato collection box. The potato collection box is located at a tail end of the separation and elevation reversing device, and configured to load the potatoes and feed weight information of carried potatoes back to the control unit.
