自动取苗装置是移栽机的核心部件。针对硬质穴盘苗设计了一种利用顶苗爪将穴盘苗顶出,并由接苗板上的夹片夹持住穴盘苗基质,随后带动穴盘苗转动90°到放苗位置的机构;穴盘可以进行水平位置和纵向位置移动,从而实现穴盘中的苗按规则取出;整个装置的运动顺序由PLC进行控制,依靠气缸作为执行元件驱动。初步试验显示,自动取苗装置能够完成硬质穴盘苗的取苗作业,取苗速度达72株min。
Automatic seedling removal device is the core part of the transplanter. Aiming at the rigid plug seedlings, a top seedling claw was used to top out the plug seedlings, and the seedling seedling matrix was held by the clips on the pickling seedlings, and then the seedling seedlings were driven to rotate by 90 ° to the position of the seedling seedling Of the body; plug can be horizontal position and vertical position of the mobile plug in order to achieve seedlings rule out; the entire device movement control by the PLC, relying on the cylinder as the actuator drive. Preliminary experiments show that the automatic seedling device can take the hard seedling seedlings take seedlings operation, take seedling speed of 72 min.
