one of two transverse ends of the conveyor belt base is a seedling supplementation side; a section of the upper conveyor belt (13) and a section of the lower conveyor belt (14), which are located on the seedling supplementation side, are seedling supplementation sections that extend in a straight line in a longitudinal direction of the conveyor belt base; the seedling supplementation sections are perpendicular to the seedling discharging sections; movement directions of the first seedling dropping cup group (15) and the second seedling dropping cup group (16) are from the seedling pick-up sections to the seedling supplementation sections, and then from the seedling supplementation sections to the seedling discharging sections; the seedling supplementation device is located on the seedling supplementation side and is close to the seedling supplementation sections; the seedling pick-up device is located on the seedling pick-up side and is close to the seedling pick-up sections;
the seedling pick-up device comprises a plug seedling conveyor belt (1); the plug seedling conveyor belt (1) is able to simultaneously convey a plurality of plug seedlings to a seedling pick-up position; the seedling pick-up position is located on one side of the plug seedling conveyor belt (1) close to the seedling pick-up sections; a supporting rod (2) is arranged on an outer side of the plug seedling conveyor belt (1); a top end of the supporting rod (2) is connected with a cover plate (3); a longitudinal guide rail (4) is arranged on a bottom side of the cover plate (3); a sliding block is arranged on the longitudinal guide rail (4); the sliding block is connected with a top end of a lifting cylinder (6); the cover plate (3) is further provided with a longitudinal conveying motor (5) capable of driving the sliding block and the lifting cylinder (6) to move along the longitudinal guide rail (4); a bottom end of the lifting cylinder (6) is connected with a transverse extension and retraction device (8) and a transverse cylinder (7) capable of driving the transverse extension and retraction device (8) to extend and contract in the transverse direction; a plurality of seedling pick-up mechanisms are mounted at intervals on the transverse extension and retraction device (8); each seedling pick-up mechanism comprises a seedling pick-up cylinder (9) and a seedling pick-up claw (10);
a seedling pick-up photoelectric sensor (11) is arranged on one side of the plug seedling conveyor belt (1); when the seedling pick-up photoelectric sensor (11) detects the plug seedlings at the seedling pick-up position, a controller enables the longitudinal conveying motor (5), the lifting cylinder (6), and the transverse cylinder (7) to cooperate to drive the plurality of seedling pick-up mechanisms to longitudinally approach the seedling pick-up position and transversely get together, thereby causing the plurality of seedling pick-up mechanisms to move above the plurality of plug seedlings located at the seedling pick-up position; a detection camera (12) is arranged on a top side of the conveyor belt base; the detection camera (12) takes photos of the plurality of plug seedlings located at the seedling pick-up position, so that the controller recognizes high-quality seedlings and low-quality seedlings at the seedling pick-up position up; the controller enables the pick-up cylinder (9) located above the high-quality seedlings to drive the seedling pick-up claw (10) to be opened and pick up the high-quality seedlings; after the seedling pick-up claw (10) picks up the high-quality seedlings, the controller makes the longitudinal conveying motor (5), the lifting cylinder (6), and the transverse cylinder (7) cooperate to drive the plurality of seedling pick-up mechanisms to longitudinally approach the seedling pick-up sections and be transversely separated, so that the plurality of seedling pick-up mechanisms respectively move above the plurality of seedling dropping cups of the first seedling dropping cup group (15) or the second seedling dropping cup group (16) located at the seedling pick-up sections; the controller opens the seedling pick-up claw (10) located above the seedling dropping cups, so that the plurality of high-quality seedlings fall into top openings of the plurality of seedling dropping cups of the first seedling dropping cup group (15) or the second seedling dropping cup group (16) respectively;
the seedling supplementation device comprises a seedling supplementation plate; the seedling supplementation plate is horizontally arranged and is located above the seedling dropping cups at the seedling supplementation sections; a seedling supplementation conveyor belt (24) is mounted above the seedling supplementation plate; the seedling supplementation conveyor belt (24) is connected with a plurality of seedling supplementation cups; seedling supplementation conveying motor (25) capable of driving the seedling supplementation conveyor belt (24) to move is mounted on the seedling supplementation plate, thereby forming a seedling supplementation cup group (26) capable of cyclically moving along with the seedling supplementation conveyor belt (24); a seedling supplementation port (27) is provided on one side of the seedling supplementation plate close to the seedling supplementation sections; the seedling supplementation port (27) is aligned with a bottom opening of the seedling supplementation cup located above the seedling supplementation port and the top opening of the seedling dropping cup located below the seedling supplementation port at the same time; a seedling supplementation photoelectric sensor (23) is arranged on the top side of the conveyor belt base; and when the seedling supplementation photoelectric sensor (23) detects that the seedling dropping cup located below the seedling supplementation port (27) is empty, the controller stops the movements of the upper conveyor belt (13) and the lower conveyor belt (14), and makes the seedling supplementation conveying motor (25) to drive the seedling supplementation cup group (26) to move, so that a seedling supplementation cup with a high-quality seedling moves above the seedling supplementation port (27), and the high-quality seedling stored in the seedling supplementation cup group (26) falls into the empty seedling dropping cup.
