Seedling taking-out guide member and rice shoot transplanting machine provided with the same

Abstract

The planting claws (22) enter the lower end of the seedling raising mat (M) to rake the seedlings (S), make the seedlings (S) pass through the seedling passage holes formed on the lower guide rail (28) and lift the seedlings (S) It is guided downward and planted on the ground. The seedling taking-out guide member (50) is provided with a seedling front guide part (50b) and a seedling side guide part (50cl, 50cr). The seedling front guide part (50b) is configured such that its front end protrudes downward in front of the planting claw passage space as a space for the planting claw to pass after passing through the rice shoot passage opening, and the rice shoot front guide part (50b) is formed to: Plant the track of the front end of claw (22). The seedling side guides (50cl, 50cr) are disposed so as to protrude downward from the side of the planting claw passage space, and the seedling side guides (50cl, 50cr) are formed so that the base ends of the seedling front guides (50b ) connection, when viewed from the side, the interval between the side seedling guides (50cl, 50cr) and the seedling front guides (50b) gradually expands towards the lower end.

Description

technical field [0001] The present invention mainly relates to a seedling taking-out guide member for guiding downward a seedling taken out from a lower end portion of a seedling mat, and a rice shoot transplanting machine provided with the seedling taking-out guide member. Background technique [0002] Conventionally, the rice shoot transplanting machine provided with the rice shoot taking-out guide member which guides the rice shoot raked from the lower end part of a seedling raising mat downward is known. Patent Document 1 discloses a rice shoot transplanter (rice transplanter) provided with a seedling guide structure as such a seedling taking-out guide member. The rice seedling guiding structure of this patent document 1 is provided in the following rice transplanter, and this rice transplanter is equipped with: the rice seedling stage, and it is placed on the seedling raising mat; and planting claws, which take out the seedlings to be raked from the seedling raising ma...

AI Technical Summary

Problems solved by technology

According to this structure, for the seedling guide structure of Patent Document 1, the seedlings picked up by the planting claws are clamped by a pair of side guide bodies on the left and right, while the seedlings are guided downward. Therefore, the seedlings are restricted. Disturbance of posture in the left-right direction

In addition, since the front surface of the seedling is guided downward along the front seedling guide body, the disturbance of the posture of the seedling toward the front is also limited.
