ROLLER COVER WITH ANGLE-ADJUSTABLE GRASS GUIDE PLATES

摘要

A roller cover with angle-adjustable grass guide plates comprises a roller cover body (1) and a connecting plate (4). Several movable grass guide plates (2) are hinged on an inner wall of the roller cover body (1), and a slotted hole (3) is formed at one end portion of each movable grass guide plate (2). The connecting plate (4) is movably restricted in a slide rail on an inner side of the roller cover body (1), and the slide rail extends longitudinally along the roller cover body (1). First fork shafts (5) are fixedly arranged on the connecting plate (4), wherein the number of the first fork shafts (5) corresponds to that of the movable grass guide plates (2), and the first fork shafts (5) are slidably restricted in the slotted holes (3) of the movable grass guide plates (2). A control mechanism for driving the connecting plate (4) to slide along the slide rail is mounted on the roller cover body (1). The roller cover with angle-adjustable grass guide plates is convenient to operate, and the mounting angles of the adjustable grass guide plates (2) can be changed by a small control force, to achieve the purpose of controlling the threshing time of crops in a threshing chamber, so that the threshing performance of the crops is improved and the threshing loss is reduced.
