Problems solved by technology

Most of the existing transplanting mechanisms use single-degree-of-freedom K-H-V non-circular gear planetary gear trains. The two-stage unequal speed transmission ratios restrict each other. The feasible resolution range of the mechanism is small, and there is a problem of side clearance accumulation. Poor and less accurate

Abstract

The invention discloses a differential non-circular gear train transplanting mechanism and method, and belongs to the field of agricultural machinery. The differential non-circular gear train transplanting mechanism comprises a driving system and a differential non-circular gear train, wherein power is input through the driving system; the driving system divides the power into two paths; the two paths of power are output to the transplanting mechanism through the differential non-circular gear train; the differential non-circular gear train comprises a planet carrier, a non-circular sun gear and a non-circular planet gear; the non-circular sun gear is engaged with the non-circular planet gear; the non-circular planet gear is arranged on a planet shaft; the planet shaft is hinged onto the planet carrier; and the two paths of power correspondingly drive the non-circular sun gear and the planet carrier. The differential non-circular gear train transplanting mechanism can be configured into a double-arm type transplanting mechanism; a plurality of transplanting arms can also be configured through optimized design; the structure is compact; the transmission is stable; the seedling injury rate is reduced; and the transplanting precision is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a differential non-circular gear train transplanting mechanism and method. Background technique [0002] The transplanting of rice and other crops is an important link in the planting process. At present, rice transplanting machines mainly include rice transplanters, rice throwing machines and pot seedling transplanters. The rice transplanter adopts blanket-like seedlings, which have a long seedling slowing period and damage the roots; the rice seedling throwing machine is easy to cause the seedlings to fall, and the uprightness is not good; while the potted seedlings are planted with good uprightness and no slowing down period. [0003] The transplanting mechanism is the core working part of the transplanting machine, which completes the actions of taking seedlings, transporting and planting. Most of the existing transplanting mechanisms use single-degree-of-fr...
