Description

  The present invention is provided with a preliminary seedling stage supported by a seedling stage support in a plurality of upper and lower stages, and a seedling scoop placed on the uppermost preliminary seedling stage among the upper and lower stages of the preliminary seedling stage. It is supported by the seedling support column so as to be able to swing up and down in a descending action posture in which a plate or a seedling box is pressed against the uppermost preliminary seedling stand and a lifting release posture in which the pressing of the seedling rake plate or seedling box is released. The present invention relates to a spare seedling storage device for a rice transplanter equipped with a holding body.

  In the above-mentioned spare seedling storage device, the preliminary seedling is placed on the seedling rake plate or placed in the seedling box together with the seedling rake plate and stored in the preliminary seedling stand, and the seedling rake plate and seedling box are emptied by using the spare seedling. Then, if the seedling scooping plate and seedling box that have been emptied are placed on the uppermost preliminary seedling stand and the presser is used, the seedling scooping plate and seedling box should be stored in a state that prevents the seedling scooping plate and seedling box from falling off. It is something that can be done.

FIG. 10A and FIG. 10B are cross-sectional views of the conventional spare seedling storage device in the empty seedling box storage state. However, this conventional seedling storage device is provided with preliminary seedling platforms 22 and 23 in two upper and lower stages.
As shown in FIG. 10 (a), in the conventional preliminary seedling storage device, if there is one empty seedling box 42 stored on the uppermost preliminary seedling mounting base 22, the free end 33 of the presser body 30 becomes the seedling. The seedling rake plate 41 in the box was lowered, and the holding body 30 was in a descending action posture so as to press the seedling box 42 against the preliminary seedling stage 22 through the seedling rake plate 41.
As shown in FIG. 10 (b), in the conventional spare seedling storage device, if there are two empty seedling boxes 42 accommodated in the uppermost preliminary seedling stand 22, two empty seedling boxes 42, 42 are stacked. Since the base end side of the presser body 30 comes into contact with the upper end of the side wall 42a of the upper seedling box 42, the free end portion 33 of the presser body 30 does not descend to the seedling rake plate 41 in the seedling box. The presser body 30 did not switch to the lowering action posture.

  Conventionally, when a seedling box that has been accommodated in a plurality of upper and lower standby seedling platforms is emptied, one seedling box can be pressed and fixed to the uppermost preliminary seedling platform, The box could not be fixed simply by being placed on the lower stage seedling stand, or even if all the seedling boxes were accommodated in the upper stage seedling stage, good pressing and fixing could not be performed.
