Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a storage mechanism for seedling growing boxes transported from a seeding plant, and also includes a seedling box pushing mechanism for transferring the seedling growing boxes from this storage mechanism to a seedling growing shelf. The present invention relates to the provided seedling box loading device.

[Conventional technology]

In the above-mentioned seedling box loading device, conventionally, the 9th
As shown in the figures and FIG. 10, the storage mechanism 8 is designed to hold the seedling raising boxes 1 from the seeding plant 7 side by side in the width direction of the seedling raising shelf 9, which has the following disadvantages. In addition, 11 is a storage mechanism 8 to a seedling raising shelf 9.
10 is a lifting mechanism for raising and lowering the seedling raising shelf 9 relative to the storage mechanism 8.

[Problem that the invention seeks to solve]

In other words, only a small amount can be stored because the seedling boxes are lined up in the width direction of the seedling rack, and empty seedling racks are loaded in the designated way instead of the seedling racks where all the shelves have been loaded with seedling boxes. Even if we try to shorten the time required to set the seedlings in the desired position, there is a limit. Therefore, while setting the empty seedling racks, we are trying to avoid supplying more seedling boxes than can be stored in the storage mechanism. It has become necessary to slow down the speed at which seedlings pass through the seeding plant, to increase the interval between feeding boxes of seedlings to the seeding plant, or to stop the seeding plant, resulting in poor work efficiency.

An object of the present invention is to prevent a decrease in the efficiency of sowing companion seeds when replacing a full seedling-raising shelf with an empty seedling-raising shelf.

[Means for solving problems]

A feature of the present invention is that the above-described seedling box loading device is configured as follows.
In other words, the storage mechanism is a mechanism that arranges the seedling boxes in the vertical direction of the seedling raising shelf and holds the parallel pitch of the seedling raising boxes in the same or almost the same way as the parallel pitch of the shelf part of the seedling raising shelf. This is a mechanism that includes a plurality of push-out units arranged vertically, and simultaneously transfers a plurality of upper and lower seedling-growing boxes held by the storage mechanism onto a seedling-growing shelf using the plurality of push-out units.

[Effect]

() As mentioned above, if the storage mechanism is structured so that the seedling boxes are arranged and supported vertically, more seedling boxes can be stored per unit area than when they are arranged horizontally as in the conventional configuration. . Then, the plurality of seedling growing boxes in the storage mechanism are simultaneously transferred to the seedling raising shelf by the seedling growing box pushing mechanism.

In this case, multiple seedling boxes are pushed out after only a short period of time when the seedling box pushing mechanism operates once, and the storage mechanism has a large room for the seedling boxes. The seedling growing boxes can be fed into the storage mechanism without any problem without slowing down the feeding speed and the speed of the seeding plant.

() If the mechanism for pushing out seedling boxes is a type that repeats the operation of pushing out the topmost seedling box in the storage mechanism, then lifting the one level below, and pushing out the lifted seedling box, The total time to transfer a predetermined number of seedling boxes onto the seedling rack is calculated by multiplying the sum of the operation time of the seedling box pushing mechanism in both directions and the time required to lift the seedling boxes multiplied by the predetermined number of seedling boxes. Become.

On the other hand, the seedling box pushing mechanism of the present invention is of a type that simultaneously transfers a predetermined number of seedling boxes in the storage mechanism onto the seedling shelf, so the total time to transfer the predetermined number of seedling boxes onto the seedling shelf is limited to one time. It is only necessary to add the time required to lift a predetermined number of seedling boxes to the reciprocating operation time.

As a result, when a predetermined number of seedling boxes are transferred from the storage mechanism to the seedling shelf, the total time for transfer is shortened according to the seedling box pushing mechanism of the present invention. Therefore, during this total reloading time, it is not necessary to feed the seedling boxes into the storage mechanism and to temporarily stop the operation of the seeding plant, or these stoppages can be done for a very short time. .

() In the above-mentioned model (a model that repeats extrusion one stage at a time), if the total time for reloading is to be shortened, it is necessary to operate the seedling box extrusion mechanism at high speed to shorten the time required for each operation. .

However, if you push out the seedling nursery box at high speed like this, when you start pushing out or stop inside the nursery shelf,
Due to this inertia, the soil inside the seedling box is biased to one side,
There may be gaps between the soil and the box, and the sown paddy near the edges of the seedling box may fall into the gaps, which is unfavorable for the growth of seedlings.

On the other hand, if the seedling box pushing mechanism of the present invention is of a type in which a predetermined number of seedling boxes are placed on the seedling shelf at the same time, the operation of the seedling box pushing mechanism does not need to be extremely fast. There are no negative effects such as uneven soil in the nursery box. Moreover, the stopping position of the seedling box after extrusion is completed is also easy to align in an orderly manner.

〔Effect of the invention〕

As mentioned above, there are two points: the storage mechanism can have a large margin for the seedling boxes in the short time it takes for the seedling box pushing mechanism to operate once, and the total time required for transferring the seedlings to the seedling shelf is short. Since there is no need to slow down the speed of feeding the seedling boxes into the storage mechanism and the speed of the seeding plant, a decrease in overall work efficiency can be suppressed.

In addition, when transferring to the seedling raising rack, there is no problem such as uneven soil in the seedling raising box, so it is possible to prevent poor growth of seedlings and reduce the rate of defective sowing. .
