The invention provides a modularized variable-aperture automatic
seedling tray
positive pressure dibbling
machine which is characterized in that a
machine body is rectangular and is provided with a discharging mechanism, a control host, dibbling modules, a telescopic rod, a fan, a fixed seat, a
pulley supporting plate frame and the like; the groove frame is connected with the main
machine frame through the telescopic rod and the fixing base, the dibbling module is inserted into the groove frame from a window on the right side of the machine body, and a
seedling raising plate is placed on the
pulley supporting plate frame. After starting up, the control host automatically pressurizes and supplements seeds for the dibbling module, after the control host automatically enters a seed discharging state, the telescopic rod works to enable the dibbling module to be in an inclined state, when seeds slide above holes,
pressure difference exists inside and outside the modules, the seeds are pressed on the holes by gas, and when redundant seeds slide to one side, the telescopic rod retracts, and the dibbling module recovers to be in a horizontal state. After seed metering is completed, the dibbling button is pressed down, the holes are enlarged, the seeds fall into the holes of the
seedling raising plate, and the machine automatically enters a seed metering state after dibbling is completed. Modularization and
automation of the seedling raising tray dibbling machine are achieved, the working efficiency of farmers is improved, and yield and income increase is facilitated.
