Transplanting mechanism of swing-type wide-narrow row rice transplanter

Abstract

The invention discloses a transplanting mechanism of a swing-type wide-narrow row rice transplanter. A left planet shaft and a right planet shaft are provided with two transplanting arms which have the same structure and swing through a pair of conjugate cams; the transplanting arms rotate around the planet shafts and periodically swing along the axle perpendicular to the directions of the planetshafts; a shell of each transplanting arm is divided into an inner layer and an outer layer to rotate; the conjugate cams are fixed to a gear box through cam flanges and are straddled on the planet shafts; shift forks matched with the conjugate cams rotate around a shift fork shaft fixed on the inner shell of each transplanting arm; one end of each shift fork is contacted with each conjugate cam and the other end is connected with the outer shell of each transplanting arm; the swinging of the shift forks is converted into swinging of the outer shells of the transplanting arms to realize swinging of seedling needles. A three-section type seedling pushing rod is adopted to finish the seedling pushing action after the transplanting arms swing at a certain angle; after taking the seedlings, the transplanting arms swing under the action of the conjugate cams so that the seedling penetrating point moves left or right relative to the seedling position and wide-narrow row distribution is formed on the seedling position under the premise that the seedling ports are distributed at intervals.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a splitting mechanism for a swing-type wide and narrow row rice transplanter. Background technique [0002] Wide and narrow row transplanting refers to the implementation of one wide and one narrow planting method for the row spacing of rice transplanting. This planting method utilizes the principle of crop marginal advantage to increase production. By adjusting the row spacing of transplanting rice seedlings, the ventilation and light transmittance between plants can be improved, and diseases can be reduced. Increase the leaf area index, prolong the life of the leaves, and accelerate the accumulation of dry matter, so as to achieve the purpose of high quality and high yield, saving cost and increasing efficiency. [0003] The separate transplanting mechanism is a component on the rice transplanter that realizes taking seedlings, implanting them in the field, and planting the seedlings i...
