Transplanting mechanism of gear driving oblique wide and narrow row seedling transplanter

Abstract

The invention discloses a transplanting mechanism of a gear driving oblique wide and narrow row rice transplanter. Both sides of a chain wheel shaft are respectively provided with a transmission box and a transplanting arm with the same structure; the transmission box has the structure that a driving gear is fixed on the end of the chain wheel shaft; the driving gear is meshed with a driven gear fixed on an output shaft; the output shaft and the chain wheel shaft are arranged obliquely in a crossed way; the end of the output shaft is fixedly connected with a planet carrier; a sun gear supported on the output shaft by a bearing is fixedly connected with the end of the chain wheel box by a flange in the planet carrier; the sun gear is respectively connected with respective planet wheels by a middle wheel; and a planet wheel shaft fixedly connected with a right planet wheel is respectively connected respective right transplanting arms. Seedling needles on the transplanting arms driven by the planet wheels move in an oblique plane; after the seedling needles are used for taking seedlings, lateral motion relative to an advance direction is generated due to the obliqueness of the planet carrier so that the transplanting points of the seedlings move leftwards or rightwards relative to seedling taking positions; on the premise that seedling taking ports are distributed at the same interval, the seedling transplanting positions are distributed in wide and narrow different row distances required by agriculture.

Description

technical field [0001] The invention relates to a transplanting mechanism of a rice transplanter, in particular to a gear-driven inclined wide and narrow row transplanting mechanism of a 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 ...

AI Technical Summary

Problems solved by technology

In the existing published transplanting mechanism documents of rice transplanters, the central axis of the sun gear on the existing splitting mechanism is coaxial with the sprocket shaft, the planet carrier is perpendicular to the sprocket shaft, and the seedling needles on the planting arm are vertical to the sprocket shaft and the ground. In-plane movement, under the premise that the seedling openings are equidistantly distributed, the transplanting position cannot form the wide and narrow row seedling distribution required by agronomy
