Seedling transplanting machine

Abstract

The present invention provides a seedling transplanting machine which can easily perform switching operation of preliminary seedling frames no matter from a front side of the machine body or from the machine body without easily grasping the seedlings or causing arbitrary machine body vibration induced shape switching of the preliminary seedling frames. The seedling transplanting machine is provided with a preliminary seedling frame (81) on a front part of a traveling vehicle body, wherein the preliminary seedling frame (81) is provided with a plurality of preliminary seedling carrying stands and a link mechanism which can switch the preliminary seedling carrying stands into a stack-up state and an unfolding state, wherein a main operational unit (86a) of the operational link mechanism is disposed behind the preliminary seedling carrying stand which is located in front the machine body in the unfolding state and on the top layer in the stack-up state, a subsidiary operational unit (86b) of the operational link mechanism is disposed in front of the abovementioned top-layer preliminary seedling carrying stand, and operational sections of the main operational unit (86a) and the subsidiary operational unit (86b) are disposed at a position where the transplanting machine leaves the preliminary seedling carrying stands.

Description

technical field [0001] The invention relates to a seedling transplanting machine for planting seedlings in farmland. Background technique [0002] The seedling transplanting machine includes a traveling vehicle body including an engine as a power source, and power transmission mechanisms such as a main transmission and an auxiliary transmission, and a seedling planting device installed at the rear of the traveling vehicle body. The structure of the conventional seedling transplanting machine is disclosed by the following patent document 1, for example. [0003] In the seedling transplanting machine of Patent Document 1, there is provided a movable preparatory seedling frame that can be switched into the following two forms, that is, two preparatory seedling loading platforms are in the unfolded form arranged in the front and rear directions of the body, and two preparatory loading platforms The seedlings are in a stacked form arranged in the up and down direction of the bod...

AI Technical Summary

Problems solved by technology

[0007] However, in the seedling transplanting machine of the above-mentioned Patent Document 1, since an operation handle is disposed on the rear side of the body of the preparatory seedling-carrying platform positioned at the front of the body when in the stacked state and in the unfolded state, there is the following problem: When loading seedlings on the preparatory seedling loading platform in front of the machine, it is difficult to switch between the unfolded form and the stacked form of the movable preparatory seedling frame from the front of the machine

[0008] Therefore, in this conventional seedling transplanting machine, the operator needs to perform the switching operation of the movable preparatory seedling frame from the traveling vehicle body every time the switching operation is performed, resulting in a reduction in working efficiency and an increase in the labor of the operator.

[0009] In addition, in the seedling transplanting machine of this patent document 1, since the operating handle is arranged on the outer side of the machine body than the preparatory seedling loading platform, the operator on the traveling vehicle body will move the movable preparatory seedling frame from the unfolded state after loading the seedlings. When switching operation to the stacking mode, the operator may mistakenly grasp the seedlings together with the operating handle

Grasping the seedlings may cause bending or destruction of the seedlings, which may lead to a decrease in the yield and quality of the seedlings due to poor growth of the seedlings.

[0010] In addition, if the seedlings are grasped, the operator needs to wash hands soiled by the seedlings or soil, so there is also a problem of additional time and labor.

Therefore, in this conventional seedling transplanting machine, there is a problem that the operator has to pay attention not to grasp the seedling field for switching operations, etc., resulting in a decrease in work efficiency and an increase in the labor of the operator.

Therefore, there is a problem that the seedling picking board sometimes falls from the vehicle body due to wind or vibration of the machine body, and the operator must pick up the dropped seedling picking board, resulting in a decrease in work efficiency and an increase in the labor of the operator.
