The invention discloses a seedling slinging mechanism, comprising: a seedling taking unit comprising a seedling cutter support and a scaling drive and a cutter head which are installed on the seedling cutter support, the cutter head comprising a first blade and a second blade which can rotate relative to each other, a seedling clamping groove being formed between the first blade and the second blade; the scaling drive is connected with the cutter head, and the seedling clamping groove of the cutter head is controlled to be scaled through the scaling drive, so that the seedling clamping groove is in a shrunk state at a seedling taking position and is in an enlarged state at a seedling throwing position; and the seedling taking driving unit is connected with the seedling cutter bracket and is used for driving the seedling taking unit to move back and forth between the seedling taking position and the seedling throwing position. In the scheme, when the tool bit rotates to the seedling throwing position, the seedling clamping groove of the tool bit can be automatically enlarged, so that the roots of seedlings are completely separated from the limitation of the bottom surface of the tool bit, the loss of throwing force caused by the obstruction of the tool bit when the seedlings are thrown out is avoided, the soil penetrating depth after the seedlings are thrown out is increased, and the growth of the seedlings is more facilitated.

    本发明公开一种抛秧机构,包括:取秧单元,包括秧刀支架以及安装于所述秧刀支架上的缩放驱动和刀头,所述刀头包括可相对转动的第一刀片和第二刀片,所述第一刀片和所述第二刀片之间形成有卡秧槽;所述缩放驱动与所述刀头连接,通过所述缩放驱动控制所述刀头的所述卡秧槽缩放,使得所述卡秧槽于取秧位置处于缩小状态,于抛秧位置处于放大状态;取秧驱动单元,与所述秧刀支架连接,用于带动所述取秧单元往返于所述取秧位置与所述抛秧位置之间。本方案中,刀头旋转到抛秧位置时,刀头的卡秧槽能够自动放大,使得秧苗的根部完全脱离刀头底面的限制,避免秧苗抛出时受刀头阻碍而造成抛出力度的损失,增大了秧苗抛出后的入土深度,更有利于秧苗的生长。
