Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, a rice transplanting machine body is equipped with a preliminary seedling mounting base, and is placed and supported by a support member for each block of each planting row from the ridge side. The present invention relates to a spare seedling accommodating device for a rice transplanter in which spare seedlings can be slide-transferred on the spare seedling mounting table in a row.

[Conventional technology]

As the above-mentioned preliminary seedling accommodation device, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-204411, both ends of the preliminary seedling mounting table are configured to be open, and each has a guide portion inclined downward. There was a structure to form.

[Problems to be Solved by the Invention]

The above-mentioned conventional structure allows the preliminary seedlings to be slid and transferred from either the left or right side of the preliminary seedling mounting table provided along the lateral direction of the rice transplanter machine, and is considered in terms of workability. However, in the above structure, when the preliminary seedlings are slid from one side in order to allow slide insertion from both the left and right sides, there is a possibility that the preliminary seedlings may accidentally project from the opposite side, and the tilt of the aircraft during the planting work. There was a possibility that the preliminary seedlings would slip out due to such reasons.

It is an object of the present invention to eliminate the above-mentioned disadvantages while having an advantage that slide transfer can be performed in a row.

[Means for Solving the Problems]

A feature of the present invention is that in the preliminary seedling accommodation device of the rice transplanter having the above-described configuration, at least one end of the preliminary seedling mounting table in the slide transfer direction receives and locks the support member that is slid from the inside. Then, it can be switched between a projecting working posture that restricts further movement of the preliminary seedling and a non-working posture that comes into contact with the supporting member that is close to the outside and retracts from the preliminary seedling moving path, and projects. The point is that a biased stopper member is attached, and the action and effect thereof are as follows.

[Work]

That is, when the preliminary seedling is slid and inserted from any one end of the preliminary seedling mounting table, the support member at the tip comes into contact with the stopper member at the end portion and retracts this downward, so that the transfer is carried out. It will be possible. Then, each spare seedling is slid from the other end side in a row, and when the tip of the support member slides to the opposite end, it is received by the stopper member at the opposite end, and further sliding movement is restricted. To do. Moreover, when a predetermined number of blocks of the spare seedlings are placed, the stopper member on the insertion side is released from contact and withdrawal, and the movement of both ends of the seedlings is restricted.

〔The invention's effect〕

As a result, it is possible to transfer the seedlings to the preliminary seedling mounting table, but it is possible to suppress excessive pushing when the seedlings are pushed and slide, and to prevent the seedlings from sliding down due to the inclination of the aircraft accompanying the progress of the aircraft. Became.
