Wide-narrow row transplanting mechanism for two-stage non-conic bevel gear of high-speed rice transplanter

In the document with the publication number CN102640604A, a non-conical bevel gear wide and narrow row splitting mechanism for high-speed rice transplanter is disclosed, but the central gear and the intermediate gear meshing with it in this document are all cylindrical gears, including helical teeth and straight teeth. , the intermediate axis and the central axis have an included angle or are arranged in parallel. Since the included angle is a staggered angle in the horizontal plane, although this angle is conducive to adjusting the seedling picking point and the seedling transplanting point, it is not necessary for the adjustment of the posture of the seedling claws when picking seedlings. However, it is unfavorable, and it is easy to cause inaccurate seedling picking and knocking on the seedling door; in addition, because the intermediate shaft and central axis of the splitting mechanism are arranged alternately in the horizontal plane, there is an intersection angle between the planetary axis and the intermediate shaft in the vertical plane, and even when the intermediate shaft When arranged in parallel with the central axis, the angle of intersection between the planetary axis and the intermediate axis in the vertical plane will become larger, making the space volume of the entire insertion mechanism larger, and it is easy to interfere with other parts of the rice transplanter
