Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a transplanter for transplanting rush seedlings.

[Prior art] The cultivation of rush plants grows shoots emerging from the root of the mother plant, and it is considered that it is better to divide the mother plant seedlings into child plants and transplant them to the field. As a rush transplanter for transplanting (rush seedlings), for example, as disclosed in Japanese Patent Application Laid-Open No. 2-171106, a tape seedling in which the seedlings are held on a continuous tape at a constant pitch has been proposed. I have.

The tape seedlings used in this transplanter are arbitrarily lengthened by loosening the mother plant to make a large number of plants, and holding the stem of the plant at a constant pitch in the tape longitudinal direction between two continuous adhesive tapes. The tape seedlings are cut in units of one plant while being mechanically fed, and are planted in a field with planting claws.

[Problems to be solved by the invention]

According to the above proposed structure, the stocked rush seedlings are handled in a state of being held on a tape, so that the taped seedlings can be supplied to the transplanting machine in a wound state or in a folded state, so that there is little risk of damaging the shoots and the handleability is excellent. However, there are drawbacks in that a large amount of time and labor are required for the preliminary processing of the seedling, that is, the production of tape seedlings, and that a dedicated device is required, and the equipment cost is high. In addition, the transplanting machine itself requires a cutting mechanism for cutting the tape at an appropriate timing, and there is a problem that the structure becomes complicated.

The present invention has been made in view of such a situation, and eliminates the need for preliminary processing of seedlings, and can transplant rush seedlings with the same configuration as a popular rice transplanter, and moreover, The purpose of the present invention is to make it easier to supply and handle rush seedlings without damaging the seedlings (especially new shoots).

[Means for solving the problem]

The technical means of the present invention, taken to achieve the above object, is configured such that a seedling storage box that houses a group of rush seedlings in a standing posture is detachable with respect to a seedling cradle that reciprocates sideways with a constant stroke, The length of the seedling storage box in the seedling vertical feeding direction is set shorter than the length of the seedling mounting table in the vertical feeding direction, and the height of the side wall is set to be shorter than the length of the rush seedling to be stored. The storage box has, at its front, a front wall member that can be switched between an open state that allows passage of rush seedlings and a closed state that prevents passage of rush seedlings, and a storage part that is stored at the rear. A rear wall for receiving the rear side of the rush seedling is provided, and the seedling pedestal receives the root side of the rush seedling supplied from the seedling storage box on the side in the vertical feeding direction above the lower end of the seedling pedestal. A vertical feeder that feeds vertically The apparatus is constituted by a transport belt long in the transport direction having a seedling resting surface for placing and supporting the rush seedlings supplied from the seedling storage box, and the seedling transport operation range is set to the range from the seedling storage box. That is, the entirety of the rush seedlings located in the range of delivery and supply to the belt is set in a range that can be sent to the lower end side of the seedling nest over the lower end in the transport direction of the delivery and supply range.

[Action]

The effect of adopting the above technical means is as follows.

In other words, rush seedlings obtained by dividing the mother plant into suitable offspring are discontinuous rose seedlings, but there is no need to take time and effort such as connecting them with tape, and the rose seedlings are stored in the seedling storage box as they are. They can be housed side by side in a standing position, transported, and supplied in boxes to the seedling rest.

During this transportation, by closing the front wall member,
The rush seedlings in the box, which are rose seedlings, can be handled without spilling, and the rush seedlings in the box can be sent forward by switching the front wall member to the open state on the seedling rest.

Also, since the height of the side wall of the seedling storage box is set to be shorter than the length of the stored rush seedling, the rush seedlings have their stems protruding upward from the seedling storage box, and are moved to the seedling storage box. The rush seedling can be handled by grabbing the stem without touching the sprout at the root when taking in and out the rush seedling.

Since the length of the seedling storage box in the seedling vertical feeding direction is set shorter than the length of the seedling mounting base in the vertical feeding direction, the seedlings stored in the seedling storage box are Even when some seedlings remain on the top, it can be replenished without hindrance. In other words, since the rush seedlings in the seedling storage box are discontinuous rose seedlings, if the length of the seedling storage box in the vertical feeding direction is equal to the length of the seedling mounting base in the vertical feeding direction, If you do not completely use up the seedlings, you will not be able to replenish the seedling rest, but in the present invention, the length of the seedling storage box is set shorter than the seedling rest as described above, With the consumption, if there is a free space on the seedling nest where a seedling storage box can be mounted, all of the rose seedlings can be mounted on the seedling nest.

In this way, when a certain amount of the seedling group is left at the end of the seedling stand in the vertical feeding direction on the seedling stand, the rush seedlings in the seedling storage box can be replenished. It is possible to avoid the inconvenience that the remaining rush seedlings become so small that the standing posture cannot be maintained and the posture at the time of seedling collection is disturbed.

In addition, the seedling rest acts on the rush seedlings in the range supplied from the seedling storage box on the side farther from the end position of the seedling rest in the seedling longitudinal feed direction, and the rush seedlings adjust the range. It is equipped with a vertical feeding device that gives a vertical feeding action so that it is sent out toward the terminal side in the vertical feeding direction of the seedlings, so that a certain seedling group is left on the seedling mounting table and the next seedling storage box Even if the seedlings are replenished, they can be fed vertically without any problems.

Further, since the vertical feeding device is configured by a transport belt capable of vertically feeding the root of the rush plant,
For example, compared to the case where a group of rush seedlings is placed on a seedling surface without a vertical feeding action and the vertical feeding is performed only by pushing in from the rear side, the entire seedling group can be sent vertically without difficulty. It is also advantageous in avoiding the occurrence of problems such as damage to the seedlings due to strong compression acting on the foliage on the rear side of the plant.

[Effect of the invention]

As is clear from the above description, the rush seedling transplanter according to the present invention exhibits the following effects.

I. The seedlings consisting of discontinuous rose seedlings that have not been subjected to preliminary processing, such as connecting with tape, can be filled in a seedling storage box and transported in a box unit, and the seedlings can be transported and supplied to the seedling stand. The seedlings can be reliably and easily done without damage.

B. While the front wall member is closed and the rush seedlings can be easily transported without spilling, opening the front wall member allows the rush seedlings to be smoothly transferred to the seedling mounting table, and the supply of the seedlings is reduced. Easy to do.

C. Grass tips protruding from the upper part of the seedling storage box can be grasped so that rush seedlings can be taken in and out without damaging the new shoots at the root, and handling of the seedlings is facilitated.

D. With a certain amount of seedlings remaining at the end of the seedling stand in the vertical feeding direction on the seedling stand, replenish all of the rush seedlings consisting of rose seedlings in the seedling storage box without trouble, and feed vertically. Therefore, there is an advantage that replenishment of the seedling posture of the rush seedling composed of rose seedlings can be performed with less disturbance.

E. Since the roots of the rush seedlings can be placed and transported vertically by the transport belt that can be transported vertically, there is little risk of damaging the seedlings by applying a strong compressing action. Can be.
