Abstract

The invention discloses a circular-elliptic knot curve gear planetary system rotating box of a transplanting mechanism. The circular-oval knot curve gear planetary system rotating box mainly comprises a sun gear, two middle wheels, two planet wheels, a planet carrier, two planting arms, two seedling needles and a stand. Due to the transmission ratio of a transmission gear of the transplanting mechanism, the transplanting mechanism is less in seedling damage during transplanting; the knot curve of the sun gear is formed by a section of elliptic arc curve ACB and a section of circular arc curve ADB which are in smooth connection with each other; the transplanting mechanism is small in vibration and free from the phenomena of seedling floating and seedling laying.

Description

technical field [0001] The invention relates to a high-speed rice transplanter, in particular to a circular-elliptic pitch gear planetary system rotary box of a splitting mechanism. Background technique [0002] The rotary splitting mechanism of the high-speed rice transplanter has the advantages of fast transplanting speed, high production efficiency and good working performance. In order to reduce the vibration of the machine and the opening of the planting hole after planting, the invention patent "circular-elliptic pitch curve gear planetary system rotary inserting mechanism" (Patent No. ZL201020684448.7) proposes a mechanism consisting of 7 non-circular gears Insertion mechanism, although the insertion effect of this mechanism is better, but the number of gears is large and the structure is more complicated, it is necessary to design a new type of non-circular gear pitch curve planetary system insertion mechanism to reduce the number of non-circular gears in the inserti...
