Sub transplanting mechanism of transplanter for female parent transplant in hybrid rice seed production

Abstract

The invention discloses a sub transplanting mechanism of a transplanter for female parent transplant in hybrid rice seed production. The sub transplanting mechanism comprises a support arm, a sprocket shaft, planting arms, crank shafts, a rocker arm, a seedling claw, a cam, a shift fork and a seedling pushing device, wherein the sprocket shaft is arranged at the front end of the support arm, the crank shafts are mounted at the two ends of the sprocket shaft respectively, the planting arms are fixedly mounted at the end parts of the crank shafts, the rear ends of the planting arms are connected with the rocker arm, the rocker arm is rotationally mounted on a brace on the front end surface of the support arm, the seedling claw and the seeding pushing device are mounted at the front ends of the planting arms, the seeding pushing device is positioned in the middle of the seedling claw, the cam and the shift fork are used for driving and mounted inside the planting arms in a matched manner, guiding hole are formed inside the planting arms above the shift fork, a spring is arranged inside the guiding holes, and the lower end of the spring props the shift fork. According to the invention, the row spacing of the planting arms on the two sides of the support arm is designed to be capable of meeting the row spacing requirements on female parent transplanting in the regions, and the complete machine of the mechanism is in an independent wheel riding-type. Therefore, the labor intensity is greatly reduced, the seedlings transplanting efficiency is improved, the farming season is shortened, and the manufacturing cost is lowered.

Description

[0001] Technical field [0002] The present invention relates to the field of rice transplanter machinery, in particular to a seedling transplanter splitting mechanism for transplanting hybrid rice seed production female parents. Background technique [0003] At present, experimental studies have shown that the row spacing required for transplanting female parent of hybrid rice seed production in some areas is about 170mm, while the row spacing of rice transplanters is mostly 300mm or 240mm, which cannot meet the requirements for hybrid rice seed production in these areas; Some female parent transplanting methods are mostly manual transplanting, which has cumbersome procedures, heavy labor, long working hours, high labor intensity, and high production costs, and will affect the yield and quality of seeds. Summary of the invention [0004] The purpose of the present invention is to make up for the shortcomings of the existing technology, and provide a seedling transplanting mechanis...

Problems solved by technology

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a transplanting mechanism for transplanting the female parent of hybrid rice seed production, which solves the problem that most of the existing hybrid rice hybrid seed production uses manual transplanting. The backward production method has high labor intensity, high production cost, and low work efficiency; at the same time, the row spacing of rice transplanters is mostly 300mm or 240mm, which cannot meet the requirements of hybrid rice seed production in this area.
