DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for placing seedlings on a seedling rest of a seedling transplanter for planting crop seedlings such as rush seedlings, for example. The seedling supply structure of the seedling transplanter configured to slide the inserted seedling supply box into the respective seedling placement portions of the seedling rest, and then pull out the seedling supply box while leaving the spare seedling on the seedling rest. About.

[0002]

2. Description of the Related Art In the seedling supply structure of the above-described seedling transplanter, conventionally, a structure for supplying seedlings is disclosed in
As disclosed in Japanese Patent Application Laid-Open No. 0604, the seedling supply box is slid and mounted on the seedling holder in a state where the rush seedlings are previously placed in a row in a detachable seedling supply box on the seedling holder. There is a known configuration in which only the bottom plate of the supply box is removed and the seedling is placed and held with the tip-side fall prevention plate and the side wall left on the seedling mounting table.

[0003]

However, in the above-mentioned conventional structure, the seedling supply box is always set on the seedling rest during the planting operation. There was a disadvantage that the seedlings could not be replenished and other workers could not store the seedlings in the seedling supply box during the planting operation, resulting in low work efficiency. Therefore, as a method of solving the above-described problem, it is conceivable to configure so that the seedling supply box is pulled out of the seedling mounting table after the seedlings are supplied, but in this case, after the seedlings are supplied, the box is supplied. When pulling out, the vertical wall on the tip side becomes an obstacle, so it is necessary to remove this vertical wall from the rear side of the machine opposite to the seedling supply side, so two workers are required. There is room for improvement in efficiency. An object of the present invention is to solve the above-mentioned disadvantages and to facilitate seedling supply work.

[0004]

According to a feature of the present invention, in the seedling supply structure of the seedling transplanter described at the outset, the vertical wall of the seedling supply box at the leading end side of the seedling supply is swung about the horizontal axis at the lower end. A movable mechanism is provided so as to be freely openable, and a lock mechanism for holding the vertical wall in a standing posture for holding the seedlings is provided. The lock mechanism is provided on the seedling rest when the seedling supply box is slid into the seedling rest. The point is that the lock operation is released by contact with the contact portion.

[0005]

In the seedling supply box, the vertical wall on the tip side in the seedling supply direction is held in the seedling holding position by the lock mechanism when the seedlings are stored, and the placed spare seedlings can be effectively prevented from falling down. When the supply box is slid into the seedling rest, the lock mechanism automatically releases the lock operation by contact with the contact portion on the seedling rest side. Try to get on the platform. then,
When the seedling supply box is pulled out rearward, the stored seedlings remain on the seedling mounting table while being transferred, and only the seedling supply box can be pulled out.

[0006]

Therefore, another worker pulls out the vertical wall of the seedling supply box on the tip side in the seedling supply direction, or slides the seedling supply box on the seedling mounting table to open the vertical wall. No extra work such as dedicated operation is required, and the worker can slide and insert the seedling supply box on the seedling cradle and then pull it out backwards, so that it can be handled by one person alone, making seedling supply work easy and efficient. It can be done.

Embodiments will be described below with reference to the drawings. FIG.
Shows a transplanter for rush plants. This seedling transplanter is provided with a seedling transplanter 2 via a link mechanism 1 at the rear of the riding type traveling machine.
Are connected. The seedling transplanting device 2 includes a seedling rest 3 which is reciprocatingly moved at a constant stroke and then has a downwardly inclined posture, a planting mechanism 4 for taking out and planting seedlings one by one from the lower end of the seedling rest 3. It is provided with a ground float 5 and the like that slide. Engine bonnet for traveling aircraft 7
A reserve seedling storage table 9 is provided on each of the left and right sides of the storage box, and a seedling supply box 8 in which reserve seedlings are placed and stored is placed and stored in each reserve seedling storage table 9.

[0008] As shown in Figs.
Are each of the seedling placement parts 1 partitioned by the strip partition wall 10.
First, the rush seedlings separated from the mother plant are placed and supported in an upright position, and the mounted seedlings are seeded by the endless rotating belt type vertical feeder 12 with projections disposed below the seedling placing surface. It is configured to feed out toward the outlet. In addition, a relatively short intermediate partition wall 1 is provided at an intermediate portion in the width direction of each of the seedling placement portions 11 in order to maintain the posture of the placed seedlings and prevent lateral displacement.
3 is formed. An intermediate partition portion 14 is formed on the bottom surface of the seedling supply box 8 so as to bypass the intermediate partition wall 13 of the seedling storage tray 3 so that the slide can be inserted into the seedling storage tray 4 and a spare seedling storage tray is provided. Even when placed on 9,
The posture of the seedlings can be maintained and lateral displacement can be prevented.
In other words, as shown in FIG. 5, a protrusion 9a is formed at a position corresponding to the intermediate partition portion 14 of the mounting portion of the spare seedling storage table 9 so as to engage with the intermediate partition portion 14. 8 is configured to prevent lateral displacement.

When supplying a spare seedling to the seedling holder 3,
After the above-mentioned seedling supply box 8 is slid from the upper side into each row seedling mounting part 11, the spare seedlings are left on the seedling placing stand 3 and the seedling supply box 8 is pulled out and removed rearward. The seedling supply work can be performed by one person from the traveling machine side. More specifically, the apparatus is configured to be slid and inserted while being placed and supported on each of the seedling placement sections 11 of the seedling supply box 8 and positioned on both sides of the intermediate partition section 14 at the seedling supply tip side of the seedling supply box 8. A pair of vertical walls 16 are pivotally connected to each other so as to be swingable and openable about the horizontal axis at the lower end. At the time of storing the seedlings, a lock mechanism R for locking and holding the vertical walls 16, 16 in the upright position is provided on one lateral outer side of the seedling supply box 8, and the vertical walls 16, 16 are connected to the intermediate partition wall 13.
It is configured so as to be able to swing freely and hold its position in an upright posture integrally via a connecting member 17 that bypasses the upper part. The lock mechanism R locks a locking member 18 that locks to an upper portion of one of the vertical walls 16 and maintains a standing posture by a helical spring 19 that is freely swingable around a horizontal axis X and hangs in a locking direction. When the seedling supply box 8 is slid into the vicinity of the end while being provided in a state of being urged to rotate in the direction, the other end of the locking member 18 is brought into contact with a contact portion 22 a formed on the vertical frame portion 22 of the seedling rest 3. It is configured to come into contact with and rotate against the urging force of the spring 19 to automatically release the locking lock. In addition, the connecting tool 17
Is provided so as to be swingable around a connection point with one of the vertical walls 16 around an axis in a direction orthogonal to a plate surface of the vertical wall, in a state where the vertical walls 16 are in the upright position, and The other vertical wall 1
6 is provided so as to be locked so as to restrict the open swing.

As shown in FIG. 1, when supplying spare seedlings to the seedling rest 3, the seedling supply box 8 is moved from the spare seedling receiving stand 9 of the traveling machine to the respective seedling placement parts 11 of the seedling rest 3. Insert the slide into. At this time, the tip of the seedling supply box 8 is
In the vicinity of the position where the sliding movement is stopped by contacting the vertical frame portion 22 erected on the
8 is a contact portion 22a formed on the vertical frame portion 22 at the other end.
To release the locking lock of the vertical wall 16. Then, each of the vertical walls 16, 16 swings and opens according to the weight of the seedling, and the seedling attempts to move onto the seedling rest 3 by its own weight. At this time, if the seedling supply box 8 is pulled out rearward, the seedlings will be transferred while being left on the seedling rest 3. Here, the vertical walls 16, 16 are integrally rocked and opened at the same timing by the action of the connecting tool 17, and the seedlings on both sides of the intermediate partition 14 are supplied almost simultaneously. And the vertical walls 16, 16
When the seedling supply box 8 is pulled out in the backward state, the connecting tool 17 comes into contact with the intermediate partition wall 13 of the seedling rest 3 and swings right and left about the connecting point with one of the vertical walls 16. Then, the engagement with the vertical wall 16 on the other side is released, and with the vertical wall 16 on the connection side, the intermediate wall 13 and the partition wall 10 can pass through and be removed.

[Other Embodiment] Instead of providing the intermediate partition wall 13 on the seedling rest 3, as shown in FIG. 6, the leading end side vertical wall 16 of the seedling supply box 8 has an integral structure over the entire width. May be used.
