Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a spare seedling accommodation device disposed above a seedling mounting base in an inclined posture, and the tip of the spare seedling accommodation device is the seedling mounting base. The state in which the preliminary seedlings are placed and held by being locked by the locking mechanism provided on the side, and the locking with the locking mechanism is released, and the tip is brought into contact with the seedling mounting table to make a spare. The present invention relates to a preliminary seedling accommodating structure for a rice transplanter, which is configured to be swingable so that seedlings can be slid and supplied.

[Conventional technology]

As a conventional structure for accommodating the above-mentioned seedlings, there is a structure which the applicant of the present invention filed previously (Japanese Patent Application No. 63-52198). In other words, the preliminary seedling accommodation device is supported so as to be disengageable with respect to the pivot shaft.

[Problems to be Solved by the Invention]

The above-mentioned conventional structure is designed so that a new spare seedling can be replenished with some spare seedlings remaining on the spare seedling storage device. However, in the above-mentioned conventional structure, for example, when the locking mechanism has a problem and the locking and holding of the preliminary seedling accommodation device cannot be released, or when the preliminary seedling is supplied prior to the detection of the residual seedling amount sensor, , It is troublesome for the worker to put his hand from a higher position above the spare seedling storage device and lift the spare seedling storage device upward to release the engagement with the rotation support shaft. There was room for improvement in this regard.

An object of the present invention is to supply a new preliminary seedling without causing seedling collapse or the like during the preliminary seedling supply, but the operation of supplying the preliminary seedling is troublesome regardless of the operation of the locking mechanism. It's about making things easier.

[Means for solving the problem]

A feature of the present invention is that in the preliminary seedling accommodation structure of the rice transplanter described at the beginning, the preliminary seedling accommodation device is a seedling placing plate on which a preliminary seedling is placed, and the seedling placing is pivotally supported on the seedling placing table side. A support frame that supports both side edges of the placing plate, and is configured to lock the tip of the seedling mounting plate to the locking mechanism,
The support frame supports the seedling placement plate so that it can be held at a predetermined position and relatively movable in the direction in which the seedling placement plate is disengaged from the locking mechanism, and the action and effect thereof are as follows.

[Action]

In other words, when the spare seedling accommodation device is in the seedling supplying state and some spare seedlings remain on the spare seedling accommodation device, when it is desired to replenish the spare seedling, the seedling placing plate is detached from the locking mechanism. The remaining seedlings can be smoothly transferred onto the seedling placing table by moving the seedlings in the direction in which the seedlings slide, that is, in the direction opposite to the seedling sliding direction. Further, when the preliminary seedling accommodation device is in the seedling placing and holding state and the preliminary seedling is supplied onto the seedling placing table, the seedling placing plate is moved slightly along the support frame and the locking mechanism is provided. The placement lock can be released and the seedling supply state can be switched.

〔The invention's effect〕

Therefore, according to the present invention, during the supply of the spare seedlings, when the new spare seedlings are supplied, the remaining seedlings can be transferred smoothly without breaking, and when the locking mechanism has a problem or the locking mechanism If it is desired to supply the preliminary seedlings before the operation, it is sufficient to slightly pull the seedling placement plate from the lower position in the sliding direction, which makes the work easier.
