Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a preliminary seedling accommodating device arranged above a seedling platform in an inclined position, and a tip of the preliminary seedling accommodating device is connected to the seedling platform. A state in which the spare seedlings are placed and held by being locked to a locking mechanism provided on the side, and a state in which the preliminary seedlings are placed and held when the locking mechanism is released and the tip of the seedlings is in contact with the seedling stand and the preliminary seedlings are placed and held. The present invention relates to a preliminary seedling storage structure for a rice transplanter that is configured to be swingable and switchable between a state in which seedlings are slid and fed.

[Conventional technology]

As a conventional preliminary seedling storage structure, there is a structure previously filed by the present applicant (Japanese Patent Application No. 63-52198). In other words, the preliminary seedling accommodating device was supported in a detachable manner with respect to its pivot shaft.

[Problem to be solved by the invention]

The above-mentioned conventional structure is designed so that new spare seedlings can be replenished while some spare seedlings remain on the spare seedling storage device.

However, in the above conventional structure, for example, if the locking mechanism malfunctions and the locking of the spare seedling storage device cannot be released, or if the spare seedlings are supplied prior to detection by the remaining seedling amount sensor, However, the operator must reach from a high position above the preliminary seedling accommodating device and lift the preliminary seedling accommodating device upward to disengage it from the rotation shaft, which is cumbersome. There was room for improvement in this respect.

An object of the present invention is to be able to supply new spare seedlings without causing seedlings to be placed on the seedlings during the supply of spare seedlings, and at the same time to eliminate the hassle of feeding the spare seedlings regardless of the operation of the locking mechanism. The point is to make it easy to do without any hassle.

[Means to solve the problem]

A feature of the present invention is that in the preliminary seedling accommodating structure of the rice transplanter described at the beginning, the preliminary seedling accommodating device includes a seedling mounting plate on which the preliminary seedlings are placed, and a seedling mounting plate that is pivotally supported on the side of the seedling platform and a support frame that supports both side edges of the seedling placement plate, and is configured to lock the tip of the seedling placement plate to the locking mechanism, and the support frame holds the seedling placement plate in a predetermined position. It is supported so that it can be held in position and relatively movable in the direction of detachment from the locking mechanism, and its functions and effects are as follows.

[For production]

In other words, when the reserve seedling accommodating device is in the seedling supply state and some spare seedlings remain on the reserve seedling accommodating device, when it is desired to supply new spare seedlings, the seedling placement plate is released from the locking mechanism. By moving the remaining seedlings in the opposite direction to the seedling sliding direction, the remaining seedlings can be smoothly transferred onto the seedling mounting table. In addition, when the spare seedling storage device is in the seedling holding state, if you want to feed the spare seedlings onto the seedling table, you can simply move the seedling table slightly along the support frame and the locking mechanism will release the seedlings. The placement lock can be released and the state can be switched to the seedling supply state.

〔Effect of the invention〕

Therefore, according to the present invention, when newly supplying spare seedlings during the supply of spare seedlings, remaining seedlings can be smoothly transferred without falling apart, and if the locking mechanism malfunctions or the locking mechanism If you want to supply spare seedlings before operation, you can simply pull the seedling placement plate slightly in the sliding direction from a low position, making the work easier.
