Description
Technical field
The present invention relates to agricultural machinery, especially relate to a kind of elliptic gear power train transplanting mechanism of eliminating backlash.
Background technology
In existing disclosed rice transplanter transplanting mechanism document, the central gear in the elliptic gear power train transplanting mechanism, idler gear and planetary arrangement mode have two kinds: orthoscopic and triangular form.The advantage that orthoscopic is arranged is that initial setting angle is determined easily, and design and calculating are all more convenient.But its volume profile is relatively large, only is applicable to high-speed transplanter.The relative orthoscopic of triangular form is arranged, and the box shape size can design forr a short time, obtains greatlyyer and module is optional, helps improving gear teeth intensity, by optimizing relevant parameter, both can be used for walk-behind type paddy-field work machine and also can be used for high-speed transplanter.
There is not backlash in elliptic gear power train mechanism from point of theory, but in actual applications, because the wearing and tearing in processing and rigging error and the use can cause elliptic gear engagement backlash to produce, cause that transplant arm produces vibration at work, influence the uniformity and the rice transplanting quality of seedling taking amount thus.In existing elliptic gear power train transplanting mechanism, do not see to be provided with the device of eliminating backlash.
Summary of the invention
For uniformity and the rice transplanting quality that solves the seedling taking amount, the purpose of this invention is to provide a kind of elliptic gear power train transplanting mechanism of eliminating backlash.The physical dimension of this mechanism is less relatively, vibrates also little.
