According to the single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism, a first crank is hinged to one end of a first link; the other end of the first link is hinged to one end of a second link; one end of a third link is hinged to the middle part of the second link, and the other end of the third link is hinged to a sliding block; the sliding block is connected with a second crank through a sliding pair; a driving circular gear is fixed together with the first crank; a driven circular gear is hinged to a machine frame and is engaged with the driving circular gear; a cam is fixedly arranged on the machine frame; the second crank is fixed with the driven circular gear; the sliding block is connected with a sliding slot of the cam through a cam pair. According to the single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism, double ring-buckle-shaped trajectories can be realized, so that the full automation of the flower transplanting machine is realized, and proper angle and speed for flower seedling casting and verticality of seedling planting are guaranteed.

Concave tooth-incomplete eccentric circle-non-circular gear planetary system vegetable seedling picking mechanism

The invention discloses a concave tooth-incomplete eccentric circle-non-circular gear planetary system vegetable seedling taking mechanism. A conventional seedling taking mechanism adopts a locking arch or a rack-incomplete non-circular transmission mechanism to achieve the purpose that the transmission ratio of a seedling taking track is greatly varied, the locking arch has large transmission impact, and the rack-incomplete non-circular transmission mechanism is not ideal in transmission ratio variation range. A central shaft of the concave tooth-incomplete eccentric circle-non-circular gear planetary system vegetable seedling taking mechanism is fixed together with a planet carrier; a central incomplete eccentric circle-non-circular gear is fixed together with a rack; central concave teeth are fixed together with the central eccentric circle-non-circular gear and are all arranged on the central shaft in a sleeving manner; a first middle circle-non-circular gear is connected with a first intermediate shaft spline; a first convex tooth is fixed with the first middle circle-non-circular gear; a second middle circle-non-circular gear is connected with a second intermediate shaft spline; second convex teeth are fixed with the second middle circle-non-circular gear; a first planetary circle-non-circular gear is connected with a first planetary shaft spline; a second planetary circle-non-circular gear is connected with a second planetary shaft spline; one end of each of a first planetary shaft and a second planetary shaft is fixed with a shell of a seedling taking claw. The concave tooth-incomplete eccentric circle-non-circular gear planetary system vegetable seedling taking mechanism is stable in transmission and small in impact.

Design Method of Conjugate Cam-Crank-Rocker Combination Flower Transplanting Mechanism

The invention discloses a conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism and a designing method thereof. A planet gear system transplanting mechanism is limited in realizing track flexibility, and a rod mechanism with double stirrup tracks is difficult in parameter designing and adjusting. The conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism is characterized in that one ends of a first conjugate cam, a second conjugate cam and a crank are all hinged to a rack through a cam shaft, the other end of the crank is hinged to the middle of a second connecting rod, a first cam swing rod, a second cam swing rod and a swing rod are fixedly connected, the first cam swing rod is connected with the first conjugate cam through a first roller, the second cam swing rod is connected with the second conjugate cam through a second roller, and the swing rod is hinged to the second connecting rod through a first connecting rod. The designing method includes: reversely solving the conjugate cams through a mathematic model of single stirrup tracks formed by an end point of the free end of the second connecting rod, coordinates of a hinged point of a fork-shaped swing rod and the rack and known rod length conditions. The single stirrup tracks are realized by changing profile of the conjugate cams to control movement laws of a rocker rod, and the conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism is simple.
