Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called shelf emergence trolley type transplanting apparatus for raising seedling boxes, and more specifically, it is provided with a support mechanism for lifting and feeding successively feeding seedling raising boxes in a shelf shape at predetermined intervals. The present invention relates to a seedling raising box transposing device having an extruding mechanism for pushing a plurality of seedling raising boxes supported by the supporting mechanism into a germination trolley provided with shelves having the same intervals as the predetermined intervals to reload the seedling raising boxes.

[0002]

2. Description of the Related Art In the so-called shelf emergence trolley system, seedlings are sown in each seedling raising box to which floor soil has been supplied, and then each seedling raising box is inserted into a sprouting trolley provided with shelves at predetermined vertical intervals. In the budding room, the sprouting process is performed, and then it is transferred to a greening trolley with a large vertical spacing, and the greening process is performed.However, when performing the work of transferring the seedling raising box in the budding trolley to the greening trolley Then, among the plurality of pushers in the push-out mechanism, the pushers at locations corresponding to the shelves of the greening cart are replaced with another long pusher for pushing the germination cart into the greening cart.

[0003]

However, in the above-described conventional structure, it is necessary to perform a troublesome work of replacing a large number of pushers with those having different specifications each time the work of loading the green truck is carried out, and the work efficiency is improved. There was a downside, and there was room for improvement. The present invention aims to eliminate the above-mentioned problems.

[0004]

A feature of the present invention is that, in the nursery box transshipment apparatus described at the beginning, a plurality of pushers for pressing and pushing each of the nursery boxes on a slide frame which can be laterally slid at a constant pitch. While supporting a predetermined number of pressing tools, with the slide movement of the slide frame, a state in which all the seedling raising boxes are transferred from the supporting mechanism to the budding cart, and the nursery boxes loaded on the budding cart. A mechanism for changing and adjusting the initial set position along the sliding direction with respect to the slide frame in a state where a predetermined number of the above are transferred to the greening trolley arranged on the outer side of the germination trolley. The push-out mechanism is configured as described above.

[0005]

[Operation] When the seedling raising boxes are loaded on the budding dolly, the raising mechanism sequentially lifts the seedling raising boxes into a shelf shape at predetermined intervals, and then the push-out mechanism pushes the seedling raising boxes on each shelf part of the budding dolly. It pushes it toward the shelf and transfers it. At this time, by setting all the pushers of the pushing mechanism so that they are all located at the same level in a straight line and sliding the slide frame by a predetermined amount, all the seedling raising boxes in the supporting mechanism are moved to the shelves of the germination cart. Can be transferred to. Next, when the germination process is completed and the process proceeds to the greening process step, a predetermined number of pressing tools [for example, 1
The initial setting position of every other pusher is changed and adjusted by the adjusting mechanism, so that the slide frame is slid by the same stroke as the predetermined amount, and the It is possible to transfer a predetermined number of vegetation trucks to the greening trucks arranged on the outer side of the budding trucks.

[0006]

Therefore, by reasonably improving the structure of the push-out mechanism, only the operation of adjusting the set position adjusting mechanism of the pusher is performed to load the germination cart and the germination cart to the greening cart. Since the same push-out mechanism can be used for the re-loading work to and from, the complicated work such as replacing a large number of pushing tools is unnecessary, and the work efficiency in the work for trans-loading nursery boxes is improved.
