The utility model discloses a cleaning structure for a low and small
crop harvester, which comprises a harvester header, a feeding
auger roller is rotatably connected in the harvester header, a fixing frame is fixedly connected on the outer wall of the harvester header, a groove is arranged on the inner side of the fixing frame, a reciprocating lead screw mechanism is arranged in the groove, and the reciprocating lead screw mechanism is fixedly connected with the feeding
auger roller. A cross beam is fixedly connected to the inner side of the reciprocating lead screw mechanism, a
hydraulic cylinder is installed at the top of the cross beam, one end of the
hydraulic cylinder is fixedly connected with the top side of the mounting frame, the cross beam is slidably connected to the inner side of the fixing frame, the mounting frame is connected to the bottom of the cross beam in a lifting mode, a
rotating drum is rotatably connected to the inner side of the mounting frame, and bristles are arranged on the outer wall of the
rotating drum; sprayers are arranged on the two sides of the mounting frame and the inner wall of the top of the mounting frame, and an
air blower is connected to the top end of the mounting frame. According to the device, the harvester header can be automatically and efficiently cleaned, and the situation that blades, soil and impurities on the harvester header cannot be cleaned due to adhesion is avoided.
