    • A tiller cover assembly covering a rotary tiller unit is provided inside thereof with rake members arranged at a spacing along the width of cultivation for sieving lumps or blocks of soil carried around by the tiller unit. Each of the raker members is made of a resilient rod which has a coiled portion toward its base end and is fixed to an attaching member at the base end above the coiled portion. The coiled portions of the rake members are projected toward an upwardly or downwardly movable rear cover of the cover assembly, permitting the rear cover to contact the coiled portions. A clearance is formed between sieving portions of the rake members extending downward from the coiled portions to their free ends and the rear cover. A protector is provided on the inner side of the coiled portions, by which the lumps or blocks of soil carried around by the tiller unit are prevented from striking the coiled portions.
    • 在其内部设置有覆盖旋转耕耘机单元的耕耘机盖组件,其中沿着栽培宽度间隔布置的耙子构件用于筛分由耕耘机单元携带的块体或块状物。 每个耙子构件由弹性杆制成,该弹性杆具有朝向其基端的盘绕部分,并且在卷绕部分上方的基端处固定到安装构件。 前刀片的螺旋部分向罩组件的向上或向下可移动的后盖突出,允许后盖接触卷绕部分。 在从螺旋部分向其自由端向下延伸到其自由端的前耙构件的筛分部分和后盖之间形成间隙。 在螺旋部分的内侧设置保护器,防止由耕耘机单元携带的土块或块被撞击到卷绕部分。
