Planting Arm

Abstract

The planting arm of the direct-taking wide-narrow row splitting mechanism belongs to agricultural machinery; the planting arm includes a planting arm shell and a cam fitted on the planting arm shell, a shift fork shaft, a shift fork, a seedling pusher and a seedling claw, and the cam The cam axis and the shifting fork axis of the shifting fork shaft are arranged in a space staggered angle, through the space staggered angle, the pusher bar and the seedling claws are perpendicular to the rice transplanter seedling door, and the pusher bar and the seedling claws are aligned with each other. The working direction of the rice transplanter is parallel; the planting arm realizes the operation of wide and narrow rows to form rectangular seedling blocks when picking seedlings, and the two sides of the claws act on the seedling blocks at the same time, and the seedlings are vertical when transplanting. The structure is simple and reasonable, and the operation quality is good. features.

Description

Technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a planting arm of a wide and narrow row splitting mechanism on a rice transplanter. Background technique [0002] In order to meet and adapt to the needs of wide and narrow row rice transplanting operations, the current wide and narrow row rice transplanters have made innovations in the separation mechanism: one is that the new sun gear shaft forms a small angle with the central axis of the transmission box; the other is that the new planetary gear shaft is in the original The planetary wheel shaft rotates at a small angle. The trajectory of the seedling claws formed in this way forms an angle with the advancing direction. After the seedlings are taken from the seedling door, they are offset outward, so that the transplanting position forms a certain lateral offset from the position of the seedling door, thereby forming a row spacing that is wider than the distance between the two seedli...

AI Technical Summary

Problems solved by technology

However, due to the above-mentioned structure, the seedling claws enter the seedling door at a small angle with the advancing direction, and at the same time, the seedling claws form a small angle with the horizontal plane when entering the seedling door, that is, the two seedling claw tips are high on one side and low on the other side when entering the seedling door. When picking seedlings, a diamond-shaped seedling block is formed, and the two seedling tips of the seedling claws do not pick seedlings at the same time; the seedling door forms a certain oblique angle with the forward direction, and the seedling claws also form a small angle with the ground when transplanting seedlings. not vertical
