A rice transplanter for co-planting parents of hybrid rice seed production and its synchronous rice transplanting method

Abstract

The invention discloses a rice transplanter for simultaneously transplanting male parents and female parents for the seed production of hybrid rice. The rice transplanter consists of a transplanting mechanism, a box moving mechanism, a longitudinal rice seedling conveying mechanism, a rice seedling box, a rice seedling boat, a tail plate and a power drive device; the transplanting mechanism comprises 12 rice seedling transplanting arms, including 10 female parent rice seedling transplanting arms and 2 male parent rice seedling transplanting arms; the female parent rice seedling transplanting arms are distributed on the two sides, and the space between adjacent female parent rice seedling transplanting arms is 177 mm; the space on one sides of the male parent rice seedling transplanting arms is 238 mm, the space on the other sides of the male parent rice seedling transplanting arms is 300 mm, the space between two male parent rice seedling transplanting arms is 291 mm; each time of transverse movement distance of the rice seedling box is 20 mm; each time of rice seedling conveying distance of the longitudinal rice seedling conveying mechanism is 18 mm; the transplanting work of male parent rice seedlings and female parent rice seedlings is finished by simultaneously transmitting power to the male parent rice seedling transplanting arms and the female parent rice seedling transplanting arms and simultaneously conveying the rice seedlings in the transverse direction and the longitudinal direction via the power drive device. By adopting the rice transplanter, labor intensity can be reduced greatly, rice transplanting efficiency can be improved, farming season can be saved, production cost can be reduced, and the problems of labor shortage, unstable seed quality and the like are solved.

Description

technical field [0001] The invention relates to a rice transplanting machine mainly used for hybrid rice seed production in Anhui and surrounding areas, in particular to a rice transplanter for co-planting parents of hybrid rice seed production. Background technique [0002] Experimental research shows that the row spacing required for transplanting the female parent of hybrid rice in Anhui and its surrounding areas is about 5.5-5.6 inches, the row spacing required for male parent transplanting is about 8-9 inches, and the distance between the parents is 7 inches on one side. 1 foot on each side. At present, the row spacing of rice transplanters is mostly 300mm or 240mm, which cannot meet the requirements of hybrid rice seed production in Anhui and surrounding areas; moreover, the sowing date of parents varies greatly, up to more than 20 days. Existing small-row-spacing hybrid rice seed-making and transplanting machines are only suitable for transplanting seedlings of the f...

Problems solved by technology

[0003] The purpose of the present invention is to make up for the deficiencies in the prior art, providing a kind of rice transplanter for the co-planting of the parents of the hybrid rice seed production, mainly for the co-planting of the parents of the hybrid rice seed production in Anhui and surrounding areas. There are following problems in hybrid rice seed production: the one, the backward production method that most of existing hybrid rice hybrid seed production uses manual transplanting, its labor intensity is big, production cost height, work efficiency is low; The 2nd, existing rice transplanter Most of the row spacing is 300mm or 240mm, which cannot meet the requirements of hybrid rice seed production in this area; third, a small number of areas have adopted hybrid rice seed production and transplanters with small row spacing, but they are only used for the transplanting of small female seedlings, and the male parent seedlings still need manual labor. to plant
