Industrialized rice seedling raising tray dividing machine and tray dividing method thereof

The invention discloses an industrialized rice seedling raising tray dividing machine and a tray dividing method thereof. An existing seedling tray distributing machine has a complex structure and high cost. The industrialized rice seedling raising tray dividing machine comprises a tray dividing mechanism, a seedling tray frame, a first sliding block, a second sliding block, a first connecting rod, a first gear, a second connecting rod, a second gear and a motor; the tray dividing mechanism comprises two upper guide rails, two lower guide rails, a first clamp plate, a second clamp plate, a third clamp plate, a fourth clamp plate, a first staggered connecting plate, a second staggered connecting plate and a supporting frame. A reciprocating motion of the tray dividing mechanism is achieved through two sets of crank sliding block mechanisms, a phase difference exists between two sets of the crank sliding block mechanisms, the third clamp plate and the fourth clamp plate move in a back-to-back direction when the
