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.

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.

The invention discloses a dry rice seedling transplanting method. The method is characterized by including the first step of seedling raising tray preparation, the second step of rice sowing and seedling raising, and the third step of rice seedling transplanting. The method has the advantages that by adopting the method, the rice yield can be increased; the survival rate of rice seedlings in dry land rice seedling transplanting can be guaranteed; rice seedling growth can be accelerated; water resources can be saved, and saved underground water or reservoir water can be used for dry-period irrigation; meanwhile, in dry land rice seedling transplanting, operation is convenient, and rice seedling transplanting efficiency is greatly improved; a coal ash matrix is used for seedling raising and has the advantages of low heavy metal content, high soil fertility, good breathability and high self-cleaning capacity, plant disease resistance can be improved by adopting the coal ash matrix which is beneficial to rice seedling production, and as the coal ash matrix contains no grass seed, the weeding issue is solved from the source; as the coal ash matrix is obtained by fermenting various wastes, on one hand, environmental pollution is reduced by fully utilizing the wastes, and on the other hand, the problem that soil is difficult to take for seedling raising is solved.

The invention discloses a seedling transplanting device for submerged plants, comprising: a seedling storage cabin, a seedling conveying assembly, a seedling transplanting assembly and a control system. It can be gathered and unfolded through the expansion and contraction of the telescopic cylinder two; the underwater ranging sensor in the control system is used to measure the depth of the ditching teeth from the bottom of the water. In the present invention, a seedling storage cabin and a conveyor belt are arranged on the workboat, and the seedlings in the seedling storage cabin can be transferred to the seedling receiving bucket through the conveyor belt; The upper sleeve is provided with a connecting pipe, and one end of the connecting pipe is provided with groove teeth. This setting enables the rice transplanting device to perform reliable rice transplanting operations on the water bottom, with high rice transplanting efficiency and good rice transplanting effect. Most of the whole rice transplanting process is mechanized, reducing labor costs.

A transplanter boat deck assembly comprises a boat deck body and a tie ridger body on the bottom of the boat deck body, and is characterized in that the boat deck body and the tie ridger body are cavities provided with a lightweight water resisting material filler. The invention can effectively prevent adhesion of mud on the boat deck assembly during marching and turning and bury of inserted seedlings at two sides of the boat deck by the mud, in order to increase a survival rate of seedling and enhance transplanting quality. The transplanter boat deck assembly has a small friction surface with the paddy field and small resistance during working, so as to increase marching speed and transplanting efficiency; besides the transplanter boat deck assembly is wear resistant, corrosion resistant and with high strength, even the boat deck body and the tie ridger body are worn through, the foaming material can prevent the mud from entering the cavity to prolong a service life; and post assembling time and labor force are reduced; therefore the invention has substantial advantage.
