The invention discloses a three-arm differential non-circular gear train transplanting mechanism, and belongs to the field of agricultural machinery. The mechanism comprises a non-circular center gear, a first-stage non-circular planet wheel, a second-stage non-circular planet wheel, a third-stage non-circular planet wheel, a planet carrier and a transplanting arm, the planet carrier and the non-circular center gear rotate in a differential mode in the same direction, and through meshing transmission between the non-circular planet wheels, on one hand, the third-stage non-circular planet wheel does turnover motion along with the planet carrier, and on the other hand, the non-circular planet wheel does non-circular motion along with the planet carrier; on the other hand, non-constant-speed rotation is conducted relative to the planet carrier. Transplanting arms are fixedly connected with the corresponding three-stage non-circular planet gears respectively, and under the constraint of the non-circular gear train, special motion trails needed by the transplanting arms are obtained. Based on the three-arm differential non-circular gear train transplanting mechanism, more ideal transplanting tracks and postures can be achieved, the requirement for large-plant-spacing transplanting is met, the moving space of the transplanting arms is large, the design flexibility is high, and the transplanting efficiency is high. By optimizing parameters of the three-arm differential non-circular gear train transplanting mechanism, transplanting tracks and postures required by different crops such as rice or vegetables can be realized.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a three-arm differential non-circular gear train transplanting mechanism. Background technique [0002] Field crops such as rice and corn and economic crops such as vegetables and tobacco can prolong the growth period of crops through seedling cultivation and transplanting, and improve the multiple cropping index and the yield and quality of crops. The transplanting mechanism is the core working part of the transplanting machine, which completes the actions of taking seedlings, transporting and planting. The existing transplanting mechanism has problems such as unsatisfactory posture, low efficiency, high seedling injury rate, and poor work reliability. At present, the transplanting of crops, especially economic crops, is mainly done manually. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a three-arm differe...
