[0002] A harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, collects the grains into a storage bin, and then transports the grains to a transport vehicle via a conveyor belt. It is widely used in the field of agricultural harvesting.

[0003] Chinese Patent Authorization Publication No. CN 212324779 U discloses a harvester header terrain-mimicking device, comprising a header for cutting, a terrain-mimicking component, a sensor, a controller, and a lifting mechanism. The terrain-mimicking component is detachably mounted on the header, and includes a movable part that contacts the surface of the field. The utility model allows the header to be adjusted at any time to ensure the quality of the harvested crops. The above-mentioned prior art solution has the following shortcomings: The movable part is driven to rotate by the flipping of the profile plate, and the rotation of the movable part is controlled by the sensor.
