The working principle of the bean harvester is relatively simple and efficient. During operation, the harvester cuts the bean crop plants from the roots by means of a cutter, and then utilizes a conveyor belt to transport the crop to the thresher. In the thresher, the legume pods are removed from the plant by mechanical action and processed through a separator and a cleaner, resulting in pure soybeans. Throughout the process, the various components work in tandem to ensure the efficiency and quality of the harvest.
