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.

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. The present disclosure greatly improves an efficiency and performance in mechanized harvesting of the potatoes, lowers a harvesting cost of the potatoes, and improves harvesting quality of the potatoes.

Crop transfer device (4) for transferring crop to a receptacle, the device comprising a conveyor (8) for transferring the crop and the conveyor defining a conveyor plane (CP). The conveyor has a conveyor outlet (10) defining an outlet direction (OD) which is the direction of the crop falling from the conveyor at the conveyor outlet. The crop transfer device (4) comprises a scanning device (12) adapted to scan the surface of crop situated below the conveyor outlet and the crop transfer device (4) comprises a mounting device (14) by which the scanning device is mounted to the conveyor (8) with a translational mobility of the scanning device with respect to the conveyor along a path (20).

This pick-up apparatus for picking up harvested root crop defines a pick-up plane and comprises a pick-up section. The pick-up section comprises a pick-up member adapted to pick up the root crop, and a cleaning member. The pick-up member defines a pick-up position with respect to the pick-up plane. The pick-up apparatus comprises a cleaning adjustment device adapted to adjust the position of the cleaning member between at least two cleaning positions, the cleaning positions being different one from another. In each of the cleaning positions of the cleaning member and while the pick-up member is in the pick-up position, the distance of the cleaning member with respect to the pick-up plane is different from the distance of the cleaning member with respect to the pick-up plane in the other cleaning position.

The pick-up apparatus (2) for picking up harvested root crop, in particular sugar beets, from a root crop heap, comprises a pick-up section (8) which defines a pick-up direction PD a pick-up plane PL and a first lateral outward direction LOD1, comprises a pick-up member (24), and a pick-up frame (20), the pick-up frame (20) having a first lateral side (36), a second lateral side (38) and forming a pick-up opening (42), the pick-up opening (42) and the pick-up direction PD defining a pick-up area PA on the pick-up plane PL. The pick-up apparatus (2) comprises a heap divider (10) adapted for dividing the root crop heap and comprising a mobile heap dividing member (100), the mobile heap dividing member is adapted to convey root crop which is situated outside the pick-up area PA into the pick-up area PA.

Crop transfer device (4) for transferring crop to a receptacle, the device comprising a conveyor (8) for transferring the crop and the conveyor defining a conveyor plane (CP). The conveyor has a conveyor outlet (10) defining an outlet direction (OD) which is the direction of the crop falling from the conveyor at the conveyor outlet. The crop transfer device (4) comprises a scanning device (12) adapted to scan the surface of crop situated below the conveyor outlet and the crop transfer device (4) comprises a mounting device (14) by which the scanning device is mounted to the conveyor (8) with a translational mobility of the scanning device with respect to the conveyor along a path (20).
