[0002] The harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and collects the grains into the storage bin, and then transports the grains to the transport vehicle through the conveyor belt. When the harvester harvests crops, the upper ears need to be cut and recycled, but after the upper part of the crop is cut off, the lower part will leave longer branches in the field, affecting subsequent farming, so most of the branches of the crop need to be cut together, leaving short branches in the field.
