Rapid rice seedling separately-transplant device of rice transplanter

Abstract

The invention discloses a rapid rice seedling separately-transplanting device of a rice transplanter and belongs to the technical field of agricultural mechanical parts. In the rapid rice seedling separately-transplanting device disclosed by the invention, a bevel gear II of a dynamic row separator is meshed with a bevel gear I; a swing driving frame I, a swing driving frame II, a turnover shell lower cover, a sun gear and a turnover shell upper cover are sequentially mounted from bottom to top on a rotating shaft of the dynamic row separator; one end of a connecting rod of a rotating disc of the dynamic raw separator is movably connected with a through hole I of the swing driving frame I by a pin shaft I; a planet wheel II, a middle wheel II, the sun gear, a middle wheel I and a planet wheel I are arranged in a turnover shell and are meshed sequentially; a rice seedling holder I is movably connected with a central hole of the planet wheel II by a planet wheel fixing shaft II and a bearing; a rice seedling holder II is movably connected with the central hole of the planet wheel I by a planet wheel fixing shaft I and a bearing. The rapid rice seedling separately-transplanting device disclosed by the invention has the advantages of effectively guaranteeing rapid and accurate seedling picking and seedling transplanting, increasing the success rate of seedling picking and seedling transplanting, reducing damage to the rice seedlings and also reducing serious abrasion caused in the prior art by simplifying the structure.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery accessories, and in particular relates to a rice seedling rapid splitting device for a rice transplanter. Background technique [0002] Generally, the splitters used in rice transplanters are mostly crank-rocker splitter mechanisms, which can only work at a frequency of 200-220 times per minute. Due to mechanical inertia and vibration, the improvement of its working speed is limited. It can only work at a frequency of 200-220 times / minute, which limits the improvement of its working speed due to mechanical inertia and vibration. Then there was a splitting mechanism made of elliptical gear mechanism or eccentric gear mechanism. The splitting mechanism of this high-speed rice transplanter mainly consists of elliptical gear mechanism or eccentric gear mechanism. Compared with the crank-connecting rod splitting mechanism, this splitting mechanism reduces the motion inertia to a certain...
