Abrégé

Provided is a uniform-rotational-speed width/breadth spacing rice seedling transplanter, comprising a vehicle frame, a seedling tray, and a transplanting mechanism; the transplanting mechanism is provided with a rotating bin (3); the two ends of the rotating bin (3) are provided with transplanting arms, and each of the transplanting arms is provided with a rice-seedling transplanting claw (4); the seedling tray is connected to a seedling tray drive mechanism, the seedling tray drive mechanism is provided with a screw shaft (5), and changing the length of the lead of the screw of the screw shaft (5) achieves a change in the speed of motion of the seedling tray, such that the rice-seedling transplanting claw (4) alternates between actually inserting twice and inserting while empty once; the rotating bins (3) are in sets of three, and the rotating bins (3) in a set are arranged equidistantly; the separation distance between two adjacent sets of adjacent rotating bins (3) is 1.5 to 2 times the separation distance of the rotating bins (3) in a set; each set of rotating bins (3) corresponds to a seedling-carrying plate (1), achieving width/breadth rows and ultimately accomplishing the objective of two-dimensional width/breadth rice seedling transplantation.

When the rice seedling transplanter is operating, it alternates between inserting while empty once and actually inserting twice, thus implementing a width/breadth spacing rice-seedling transplantation method; the invention has a simple structure and good stability.

Abrégé

A double-mat-seedling wide-and-narrow-row rice transplanter comprises a frame, a seedling table, and a transplanting mechanism. The seedling table comprises several seedling trays. 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 (33) is disposed at a lower end. Transplanting arms are disposed at two ends of the rotary box. A transplanting claw 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 seedling tray is formed of by two standard mat seedling grooves (1) being connected in parallel. The rice transplanter improves air circulation and light passing between plants, thereby ensuring reliable production space.

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.

Each group of rotary boxes corresponds to one seedling tray (1). The wide-and-narrow-row rice transplanter effectively improves air circulation and light passing between plants, thereby ensuring reliable growth space for plants.
