Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention stores tape seedlings formed by attaching a bundle of crop seedlings at predetermined intervals in the longitudinal direction of the tape in a zigzag manner in a vertically overlapping state. The present invention relates to a storage mechanism of a tape seedling making device provided with a seedling storage section.

[Conventional technology]

In the storage mechanism of this kind of tape seedling making device, the seedling storage part composed of the bottom wall and the peripheral wall for receiving the tape seedlings can be integrally lifted and lowered, and the piled up volume of the tape seedlings becomes higher, The tape seedlings are lowered so as to be away from them, and the height of the tape seedlings supply portion and the tape seedling placement surface of the seedling storage section is always kept constant to reduce the disorder of the tape seedlings.

[Problems to be Solved by the Invention]

However, in this case, since the side wall of the seedling storage unit also moves up and down as a unit, the seedling storage unit can only come close to the position where the upper end of the side wall reaches the tape seedling supply site. Therefore,
At least the vertical distance between the tape receiving surface of the seedling storage portion that receives the tape seedlings and the tape seedling supply portion is equal to or greater than the height of the peripheral wall of the seedling storage portion. Then, since the distance between the tape seedling supply site and the tape mounting surface of the seedling storage unit becomes large, the storage posture of the tape seedlings hung from the tape seedling supply unit and put into the seedling storage unit may be disturbed. . In other words, the tape seedling situation is constructed by attaching a crop seedling bundle to the tape with a large volume root part on one side and a small volume stem tip on the other side, so the tape in the process of being hung There is a problem that the seedlings are likely to be twisted, the storage posture is disturbed, and the seedlings are entangled with each other and the seedlings are damaged when the stored seedlings are delivered at the time of planting.

An object of the present invention is to provide a tape seedling that can be folded and stored in the seedling storage portion while suppressing the posture disorder of the tape seedling by reducing the distance between the tape seedling supply site and the tape mounting surface of the seedling storage portion. There is a point to do.

[Means for Solving the Problems]

The characteristic configuration according to the present invention is that the seedling storage portion is composed of a peripheral wall and a bottom wall for receiving the tape seedlings, a mechanism for reciprocating the seedling storage portion in the lateral direction is provided, and the bottom wall is There is a mechanism for relatively moving up and down from the position corresponding to the upper end portion of the peripheral wall to the position corresponding to the lower end portion, and the action and effect thereof are as follows.

[Work]

In other words, by the reciprocating movement of the seedling storage section in the lateral direction, the tape seedlings with the crop seedling bundles attached at predetermined intervals in the tape longitudinal direction are spread over both walls in the lateral movement direction in the peripheral wall of the seedling storage section. Now you can automatically store it in a zigzag shape.
Further, by raising and lowering only the side wall for receiving the tape seedlings in the seedling storage section, the tape seedlings can be stored in a state where the height from the tape seedling supply site to the tape seedling placement surface on the seedling storage section side is always constant. Moreover, since the bottom wall can be relatively raised to the position corresponding to the upper end of the peripheral wall, the peripheral wall of the laterally moving seedling storage unit can be compared with the conventional seedling storage unit that raises and lowers the peripheral wall and the bottom wall integrally. The actual distance from the tape seedling supply portion to the tape seedling placement surface on the seedling storage portion side can be made small without contacting the seedling supply portion.

〔The invention's effect〕

Therefore, it is possible to reduce the chance that the tape seedling hung from the tape seedling supply part to the seedling storage portion will twist, and even if twisting occurs, the amount of twist can be reduced by the short drooping interval, It has become possible to automatically store the seedlings in a zigzag shape in a suitable state while suppressing the entanglement of the seedlings in the storage section.
