A two-dimensional wide-narrow-interval rice transplanter comprises a frame, a seedling table, and a transplanting mechanism. The seedling table comprises several seedling trays (1). The transplanting mechanism comprises several transplanting boxes (2) disposed in a single row, an upper end of the transplanting box is connected to a driving mechanism, and a rotary box is disposed at a lower end. Transplanting arms are disposed at two ends of the rotary box, A transplanting claw (4) is disposed on each transplanting arm. Three rotary boxes make a group, the rotary boxes inside the group are disposed at an equal interval, and an interval between adjacent rotary boxes of two adjacent groups is 1.5 times to 2 times of an interval between rotary boxes inside a group. Each group of rotary boxes corresponds to one seedling tray. The driving mechanism is a non-constant-speed driving mechanism, and the transplanting box actuates periodic motion of the rotary boxes. The rice transplanter enhances air circulation and light passing between rice seedlings, thereby improving a yield. |
