Rice seedling transplanter

Abstract

The invention relates to a rice seedling transplanter. The rice seedling transplanter comprises a traveling mechanism, a driving mechanism, a separate planting mechanism and a seedling conveying mechanism, wherein the traveling mechanism comprises a rubber caterpillar track, an anti-sinking plate and a chassis and is applicable to different pavements, the rice seedling transplanter is prevented from being get stuck in a rice seedling bed, and the steady advancing of the rice seedling transplanter in the seedling planting process is ensured; the driving mechanism adopts belt driving and has the advantages of steadiness in driving and low cost; the separate planting mechanism adopts a chain wheel to drive a group of crank and slide rod mechanism to move, a slide rod is provided with a seedling separating fork for realizing a seedling separation action, not only can quick-return characteristics be achieved, but also the seedling separating fork is enabled to have almost constant-speed movement in a working stroke, the seedling separating efficiency is high, and the empty rate is relatively low; and the seedling conveying mechanism is formed by connecting a linkage mechanism, a ratchet wheel mechanism and a group of rubber crawler-track conveyor belt wheel, the length of a crank can be adjusted to control a rotating angle of a ratchet wheel so as to control a feeding amount of the crawler belt wheel, and the rice seedling transplanter has the characteristics of high controllability, stability in feeding, applicability to seedlings with different soil amounts and the like.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a rice transplanter. Background technique [0002] With the continuous improvement and rapid development of human social productivity, the world has entered an era of more and more mechanization. Agriculture, as the foundation of human survival, has been especially valued by people. Since Japan applied for the first rice transplanter patent in 1898 , The rice transplanter has been being reformed and updated. At present, most of the moving trajectories of the transplanting mechanisms of the rice transplanters on the market are arcs, and there is a high empty insertion rate, and the seedling delivery mechanism cannot adapt to the seedlings with different soil amounts. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a rice transplanter so that the moving track of the transplanting mechanism is a straight line, and ...
