Harvester impurity discharging mechanism and corn harvester

Abstract

The invention discloses a harvester impurity removal mechanism and a corn harvester, and the harvester impurity removal mechanism comprises an impurity removal fixing cylinder assembly, the impurity removal fixing cylinder assembly comprises an impurity removal cylinder, a flexible part assembly comprises a flexible part, and the first end of the flexible part is connected with a bottom plate of the impurity removal cylinder; the movable cover plate assembly is used for shielding the limiting opening, the fixed end of the linear driving part is hinged to the top of the impurity discharging barrel, the movable end of the linear driving part is hinged to the movable cover plate assembly, and the linear driving part is used for driving the movable cover plate assembly to rotate relative to the impurity discharging barrel so as to shield or open the limiting opening. The second end of the flexible part is driven by the movable cover plate assembly to be bent so as to adjust the direction of the impurity discharging channel. The flexible part is arranged on the bottom plate of the impurity discharging barrel, the movable cover plate assembly is arranged at the top of the impurity discharging barrel, the impurity discharging channel is defined by the movable cover plate assembly and the flexible part, the linear driving part drives the movable cover plate to rotate, the direction of the impurity discharging channel is adjusted, and the adaptability of the impurity discharging mechanism is improved.
