Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare seedling container used for transporting a large number of spare seedlings to ridges or farm roads adjacent to a field and making them stand by.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned container for spare seedlings has been constructed by arranging a plurality of shelves on which a plurality of spare seedlings are placed in a fixed frame in a horizontal posture aligned in a plurality of stages.

[0003]

[Problems to be Solved by the Invention] Generally, the supply of the spare seedlings from the container for the spare seedlings placed on the ridges or the farm roads to the rice transplanter in the field is carried out in the direction of taking out the spare seedlings from the container for the spare seedlings each time. It is carried out along a transportation rail that is handed over to the spare seedling container and the rice transplanter. However, when the preliminary seedling container is configured as in the above-mentioned conventional technique, the preliminary seedling removal direction of the preliminary seedling container is determined by the posture when the preliminary seedling container is positioned on a ridge or a farm road. When supplying the spare seedlings from the spare seedling container to the rice transplanter via the transport rail,
It is necessary to ensure that the rice transplanter is positioned in the fixed preliminary seedling removal direction. In other words, if the rice transplanter is stopped at a position that is slightly out of the preliminary seedling removal direction of the spare seedling container, the transport rail cannot be passed to the spare seedling container and the rice transplanter, and the spare seedling is not transferred. Since it becomes impossible to supply the rice, the rice transplanter has to be moved again so as to be positioned in the spare seedling removal direction of the spare seedling container.

Further, in the above-mentioned conventional container for spare seedlings, since the shelves on which a plurality of spare seedlings are placed are arranged in a horizontal posture, the spare seedlings are put in and out from the back side of the shelves. In that case, it is necessary to perform work such as pulling out the preliminary seedling from the back side or pushing it in the back side, and especially for high-level shelves and low-level shelves, it is impossible to stretch or bend the work. Since it is necessary to carry out in the above, it has been a laborious and troublesome task to put the spare seedlings in and out of each shelf of the spare seedling container.

An object of the present invention is to facilitate positioning of the rice transplanter with respect to the spare seedling container when supplying the spare seedling from the spare seedling container to the rice transplanter by using the transport rail, and to secure the spare seedling container. The purpose is to reduce the labor required for placing the spare seedlings on each shelf and supplying the spare seedlings from the spare seedling container to the rice transplanter.

[0006]

In order to achieve the above object, in the invention according to claim 1 of the present invention, a spare seedling placement is provided in which shelves on which a plurality of spare seedlings are placed are arranged in a plurality of stages. And a support pedestal that rotatably supports the preliminary seedling placement portion around the axis of the vertical axis, and each shelf has a horizontal posture and a tilted posture in which the rack is lowered frontward in the preliminary seedling take-out direction. The posture can be switched to and.

According to the first aspect of the present invention, since the preliminary seedling placing portion is configured to be rotatable around the axis of the vertical axis, the preliminary seedling container can be placed on a ridge or a farm road. There is no inconvenience that the posture determines the preliminary seedling removal direction of the preliminary seedling container. In other words, when supplying the preliminary seedlings from the preliminary seedling container to the rice transplanter using the transport rail, even if the rice transplanter is stopped at a position deviated from the preliminary seedling removal direction of the preliminary seedling container, the preliminary seedling placement is performed. By rotating the part around the axis of the vertical axis, the rice transplanter can be positioned in the preliminary seedling removal direction of the preliminary seedling container without the trouble of moving the rice transplanter again.

[0008] Further, since each shelf is configured to be capable of switching the posture between a horizontal posture and an inclined posture in which the front seedling is lowered toward the preliminary seedling take-out direction, a large number of spare seedlings placed on the shelves are spared. When loading a container for seedlings on a truck etc. and transporting it to ridges or farm roads adjacent to the field, by switching each shelf to a horizontal position, the spare seedlings placed on each shelf are reserved due to their own weight. It is possible to prevent sliding in the seedling removal direction. On the other hand, when taking out the spare seedlings from each shelf of the spare seedling container and supplying them to the rice transplanter, by switching the shelf from which the spare seedlings are taken out to an inclined position, the front side of the shelf (the lower side of the spare seedling taking out direction) Side), the spare seedlings on the back side of the shelf (the upper side in the spare seedling take-out direction) after taking out the spare seedlings and supplying them to the rice transplanter can be pulled out to the front side of the shelf with a small manual pulling force. Sliding can be performed by the weight of the spare seedling or by the weight of the spare seedling only. In other words, it is possible to transport the spare seedlings in a stable horizontal position when transporting the spare seedlings by a truck, etc., and when taking out the spare seedlings from each shelf of the spare seedling container, pull out the spare seedlings on the back side of the shelf to the front side of the shelf. You will be able to reduce your effort. Especially when it was possible to pull out the spare seedlings on the back side of the shelf by sliding only by the weight of the spare seedlings, the pull-outs of the spare seedlings located on the back side of the higher or lower shelves were stretched or bent. Since it is not necessary to perform it in an unreasonable posture, it is possible to considerably reduce the labor required for taking out the spare seedlings from each shelf of the spare seedling container.

Therefore, according to the first aspect of the present invention, it is easy to align the rice transplanter with the spare seedling container when the spare seedling container is supplied to the rice transplanter using the transport rail. Also, it has become possible to reduce the labor required to supply the spare seedlings from the spare seedling container to the rice transplanter.

According to the second aspect of the present invention,
In addition to the invention described in claim 1, the tilt direction of each of the shelves can be switched.

According to the second aspect of the present invention, in addition to the horizontal posture and the inclined posture in which the shelves are lowered frontward in the preliminary seedling taking-out direction, the shelving postures in which the racks are raised forward in the preliminary seedling taking-out direction are provided. Therefore, when placing the spare seedlings on each shelf of the spare seedling container, when the spare seedlings are placed on the shelves, the shelf is tilted so that the racks on which the spare seedlings are placed are raised toward the front of the spare seedlings. By switching to, the placement of the spare seedlings on the back side of the shelf (upper side in the preliminary seedling removal direction) is changed to the front side of the shelf (lower side in the preliminary seedling removal direction).
It is possible to perform the sliding by the slight pushing force of the spare seedling placed on the table and the weight of the spare seedling or by the weight of the spare seedling alone. That is, when the spare seedling container is placed on each shelf of the spare seedling container, the labor required to push the spare seedling on the front side of the shelf into the back side of the shelf can be reduced. Especially when it is possible to push the preliminary seedlings to the back of the shelves by sliding only by the weight of the preliminary seedlings, pushing the preliminary seedlings located on the front side of the high shelf or the low shelf makes stretching or bending. Since it is not necessary to carry out the work in a complicated posture, it is possible to considerably reduce the labor required for placing the spare seedlings on each shelf of the spare seedling container.

Further, since the spare seedling placement portion is configured to be rotatable around the axis of the vertical axis, the spare seedling container is fed into the spare seedling container (when the spare seedling is taken out, the spare seedling is taken out. ) Can be directed to the direction in which the spare seedlings are placed, further reducing the labor required for placing the spare seedlings on the shelves of the spare seedling containers, and at the same time, in each rack of the spare seedling containers in a narrow space. It becomes possible to easily place the spare seedlings on.

Therefore, according to the second aspect of the present invention, it is easy to align the rice transplanter with the spare seedling container when the spare seedling container is supplied to the rice transplanter by using the transport rail. In addition to reducing the labor required to supply the spare seedlings from the spare seedling container to the rice transplanter, the labor required to place the spare seedling on each shelf of the spare seedling container can be reduced. It became so.

In the invention according to claim 3 of the present invention,
A spare seedling placement part in which a plurality of shelves on which spare seedlings are placed are aligned and arranged, and a support pedestal part that supports the spare seedling placement part rotatably around the vertical axis, Each shelf was equipped with alternate tilted postures, and a drop port was formed at the lower end of each shelf other than the lowest stage.

According to the third aspect of the invention, as in the case of the first aspect of the invention described above, when supplying the preliminary seedlings from the preliminary seedling container to the rice transplanters using the transport rail, the rice transplanters are spared. Even if the seedling container is stopped at a position deviated from the preliminary seedling take-out direction, by rotating the preliminary seedling placement part around the vertical axis, the rice transplanter does not need to be moved again without the need to move the rice transplanter. The container can be positioned in the spare seedling removal direction.

Further, since a plurality of shelves are installed in alternate tilted postures and a drop port is formed at the lower end of each of the shelves other than the lowermost one, a preliminary seedling is prepared from the lower end of the shelf located at the lowermost one. When the seedlings are taken out, the spare seedlings placed on the respective shelves are slid by a slight pushing force or pulling force manually and the self-weight of the spare seedlings, or by only the self-weight of the spare seedlings, in order from the one located below, The shelves are moved toward the lower end side or dropped from the drop openings formed at the lower ends of the shelves other than the lowermost one to the upper ends of the shelves located immediately below the shelves. That is, the spare seedlings placed on each shelf of the spare seedling container can be continuously taken out from the lower end of the shelf located at the lowest stage without changing the posture of the shelf, and the spare seedlings on each shelf can be removed. It is possible to reduce the labor when moving to the lower end of the lowest shelf (preliminary seedling take-out position).

Therefore, according to the third aspect of the present invention, it is possible to facilitate the positioning of the rice transplanter with respect to the spare seedling container when supplying the spare seedling from the spare seedling container to the rice transplanter using the transport rail. At the same time, the labor required to supply the spare seedlings from the spare seedling container to the rice transplanter can be further reduced.
