[0021] Working process:
[0022] During operation, the broad bean harvester conveys the harvested broad beans to the threshing box 2 through the conveying mechanism. At the same time, the motor drives the rotating shaft 406 to rotate, further driving the crank 405 to swing. The crank 405 drives the slider 403 to move back and forth through the connecting rod 404, thereby driving the rubbing plate 401 to move back and forth, and cooperates with the threshing roller group 3 to reciprocate and rub the broad bean pods, so that the broad bean shells are separated from the broad bean grains, reducing the phenomenon of incomplete threshing, and realizing the threshing function of the broad beans. The threshing effect is obvious and the threshing efficiency is high, which can meet the production needs of users. At the same time, the labor intensity of workers is greatly reduced, saving time and effort; the broad bean grains and broad bean shells after threshing fall into the screening bucket 6 through the gap between the threshing rollers 301, and the broad bean grains are discharged into the collection box along the mesh of the screen 601, and the pea shells slide down to the discharge port 602 for discharge; the broad bean grains and broad bean shells can be effectively and quickly screened out, and the screening efficiency is high.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
