[0017] Beneficial Effects

[0018] The present invention provides a corn stalk and ear harvester with threshing function. Compared with the prior art, it has the following beneficial effects:

[0019] (1) This corn stalk and ear harvesting machine with threshing function drives the rotating shaft to rotate by setting a driving component, thereby driving a pair of threshing rollers to rotate relative to each other for threshing. After the corn threshing is completed, the corn kernels and corn cobs fall from between the pair of threshing rollers onto the inclined plate, and the corn kernels can fall into the collection box through the square holes, while the corn cobs slide off the inclined plate. The rectangular bars can block the corn kernels without affecting the falling of the corn cobs, and then the screening component is set to prevent the fallen fluff and waste from falling together for screening, and the fluff and debris are separated by the separation component.

[0020] (2) The corn stalk and ear harvesting machine with threshing function can rotate a pair of discs, thereby driving the vertical plate to move up and down through a rotating sliding rod, thereby driving the vertical plate to vibrate up and down, thereby driving the screen plate to vibrate up and down, so that corn kernels and fluff can be screened on the screen plate, and at the same time, the screen plate can be prevented from being blocked by fluff and corn kernels, and the corn kernel screening speed can be accelerated, thereby improving the collection speed.

[0021] (3) The corn stalk and ear harvesting machine with threshing function uses a fan to blow low-power air to the material on the screen plate without blowing the corn grains. The waste crumbs and fluff are blown up without blowing the corn grains, so that they can be absorbed and transported out of the collection box by a vacuum pump. This avoids the difficulty of blowing the waste crumbs and fluff out of the collection box when the fan power is low, and the influence of the collection of corn grains when the fan power is high, thereby playing an auxiliary role. Filters are provided in the rectangular air intake and strip air supply ports. BRIEF DESCRIPTION OF THE DRAWINGS
