Power transmission device and method for male parent two-row rice transplanter for hybrid rice seed production

Abstract

The invention discloses a power transmission device of a two-line male parent rice transplanting machine for use in hybrid rice seed production and a method of the device. The power transmission device comprises an engine, a transmission shaft, a planting gearbox, a box moving spiral shaft, a connecting rod, a front transplanting mechanism, a rear transplanting mechanism, a front rice transplanting stage, a rear rice transplanting stage, a front transmission shaft, an intermediate transmission shaft, a rear transmission shaft and a transmission case which are arranged on a frame, wherein an output shaft of the engine is connected with an input shaft of the planting gearbox; an output shaft of the planting gearbox is connected with an input shaft of the transmission case through the intermediate transmission shaft; the engine is used for transmitting power to the front transplanting mechanism, the front rice transplanting stage, the rear rice transplanting stage and the transmission case in sequence through the planting gearbox, and then power is transmitted to the rear transplanting mechanism through an output shaft of the transmission case. By adopting the power transmission device for the two-line male parent rice transplanting machine in hybrid rice seed production, power transmission of two-line male parent rice transplanting can be realized, triangular distribution of large seedlings and small seedlings on two lines of hybrid rice male parent ridges is realized after transplanting, and synchronous transplanting of large and small seedlings is realized.

Description

technical field [0001] The invention relates to a rice transplanter, in particular to a power transmission device and a method for a male-parent two-row rice transplanter for hybrid rice seed production. Background technique [0002] In order to ensure that the male parent and the female parent meet at the flowering stage in the hybrid rice seed production process to improve the quality and yield of the hybrid seed production, the male parent needs to provide a longer pollen period so that the female parent at different flowering stages can be pollinated. In order to achieve this goal, it is generally required to plant seedlings of two male parents with a certain age difference in two phases and in two batches. Two times the spacing between the plants is planted at intervals, so that the large seedlings of the two rows of male parents are distributed in a "pin" or triangle, and the small seedlings of the male parents are inserted between the large seedlings every other day, ...
