Transplanting mechanism special for male parent two-line transplanting of hybrid rice seed production

Abstract

The invention discloses a transplanting mechanism special for male parent two-line transplanting of hybrid rice seed production. The transplanting mechanism comprises a transmission part, a left transplanting mechanism and a right transplanting mechanism, wherein the left transplanting mechanism and the right transplanting mechanism are in symmetrical structures, the left transplanting mechanism is respectively in hinge connection with the left end of a gear shaft of the transmission part and the rear left part of a transmission case through a left crank shaft and a left rocker shaft, the right transplanting mechanism is respectively in hinge connection with the right end of the gear shaft of the transmission part and the rear right part of the transmission case through a right crank shaft and a right rocker shaft, and the crank of the left crank shaft and the crank of the right crank shaft are arranged by 180 degrees at two ends of the gear shaft. By adopting the transplanting mechanism, the left seedling claw of the left transplanting mechanism and the right seedling claw of the right transplanting mechanism realize a two-row staggered transplanting function, the final transplanting effect of the one-stage two-row male parent is 'delta-shaped'or triangular, specific agronomic requirements of male parent one-stage two-line interval transplanting of the hybrid rice seed production can be met, seedling intervals are uniform, the seedling transplanting quality is good, the production efficiency is high, and the labor intensity of the hybrid rice seed production is effectively reduced.

Description

technical field [0001] The present invention relates to agricultural machinery, in particular to a special transplanting mechanism for two-row transplanting of male parents in hybrid rice seed production, which realizes two rows of staggered transplanting and meets the trajectory requirements of two-row interval transplanting of male parents in the first phase of hybrid rice seed production. Reduced the labor intensity of hybrid rice seed production. Background technique [0002] Hybrid rice seed production is a field production process in which the male sterile line (female parent) and the male sterile line restorer line (male parent) are artificially cultivated to achieve cross-pollination and fruiting. It is one of the important links to achieve high rice yield. The key to hybrid rice seed production is to ensure that the flowering periods of the male and female parents meet. In the production practice of hybrid rice seed production, the flowering period of the male pare...

Problems solved by technology

At present, the manual planting method is usually used to plant the male parent in stages, which is not only labor-intensive and difficult to complete properly, but also the seedling spacing is uneven after manual planting, and the straightness and parallelism of the ridges are poor, resulting in poor planting quality. It is conducive to the growth and pollination of seedlings in the later stage; the transplanting mechanism of the existing rice transplanter is to plant seedlings synchronously, which cannot meet the requirements for planting hybrid rice male parents at intervals
