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 stand of a seedling transplanter for planting crop seedlings such as rush seedlings.

[0002]

2. Description of the Related Art As a seedling supply structure of the above-mentioned seedling transplanter, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 3-10604, seedlings are preliminarily placed in a row in a detachable seedling supply box on a seedling holder. Then, slide the seedling supply box on the seedling rest,
There is known a configuration in which only the bottom plate of the seedling supply box is removed and the seedling is placed and held with the tip-prevention plate and the side wall left on the seedling mounting table as they are.

[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. An object of the present invention is to solve the above-mentioned disadvantages and to efficiently supply seedlings.

[0004]

A feature of the present invention is that a seedling supply box for replenishing seedlings is openable and closable at one end on the lower side when the seedling supply box is mounted on a seedling cradle of a transplanter. A shutter is provided, and a lock mechanism for holding the shutter in an upright posture for holding the seedlings is provided, and an operating tool for operating the lock mechanism is provided at a position opposite to the shutter existing side of the seedling supply box, and the operating tool and the operating tool are provided. The point is that a connecting member for linking with the lock mechanism is disposed outside the seedling supply box.

[0005]

According to the above construction, after the seedling supply box containing the spare seedlings is slid from above into the seedling cradle, the lock mechanism holding the shutter in the closed position is released by, for example, operation from the hand side. The shutter on the tip side is opened, and the stored seedlings can be transferred and supplied onto the seedling mounting table. Thereafter, the seedling supply box is pulled out rearward to complete the supply of the seedlings.

[0006]

Therefore, according to the present invention, even when seedlings are left on the seedling rest, only the seedlings stored in the seedling supply box can be easily replenished. It has become possible to improve work efficiency. In addition, since the connecting member for linking the lock mechanism and the operating tool for operating the locking mechanism is located outside the seedling supply box, the stored seedlings are prevented from being damaged by contacting the connecting member, and the seedlings without damage are supplied. Now you can.

Each seedling placement part 11 partitioned by the strip partition wall 10
At the same time, the rush seedlings separated from the mother plant are placed and supported in an upright position, and the seedlings are taken out by the endless rotating belt type vertical feeding device 12 provided with projections disposed below the seedling placing surface. It is configured to send out toward the mouth. In addition, a relatively short intermediate partition wall 13 is provided at an intermediate portion in the width direction of each strip seedling mounting portion 11 in order to maintain the posture of the mounted seedling and prevent lateral displacement.
Is formed. On the bottom surface of the seedling supply box 8, the intermediate partition portion 1 is arranged so as to bypass the intermediate partition wall 13 of the seedling rest 3.
4 so that the seedling can be slidably inserted into the seedling stand 4 from above, and that the seedling can be held and prevented from laterally displacing even when the seedling is placed on the spare seedling storage stand 9. is there.

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, as shown in FIGS.
The slide guide is formed in such a manner that the placement guide portion 15 formed on the lateral upper edge of the seedling is placed and supported on the upper part of the partition wall 10 of the seedling placing base 3 and is slid and inserted. A pair of vertical wall-shaped shutters 16, 16 located on both sides of the intermediate partition portion 14 are provided so as to be swingable and openable around the horizontal axis at the lower end. When the seedlings are stored, a lock mechanism R that locks and holds the shutters 16 and 16 in the upright position is provided on one lateral outer side of the seedling supply box 8, and the shutters 16 and 16 are positioned above the intermediate partition wall 10. It is configured so as to be able to swing open and hold its position in a standing posture integrally via a detouring connecting member 17. As shown in FIG. 4, the lock mechanism R locks a locking member 18 that locks on the upper part of one of the shutters 16 and maintains a standing posture in a freely swingable manner around the horizontal axis X and in the locking direction. Winding spring 1
9, a rod-shaped interlocking member 20 connected to the other end is extended to the lower end of the seedling supply direction, and a seedling rest is mounted on the other end of the interlocking member 20. An operating tool 21 is provided to abut and lock the end of the third partition wall 10. Further, the connecting tool 17 is provided with each shutter 16,
In a state where the shutter 16 is in the upright position, the other shutter 1 is provided so as to be swingable around a connection point with one of the shutters 16 around an axis in a direction orthogonal to the shutter plate surface.

When supplying spare seedlings to the seedling rest 3, the seedling supply box 8 is slid from the spare seedling receiving stand 9 of the traveling machine into each of the seedling placement portions 11 of the seedling rest 3. At this time, before the tip of the seedling supply box 8 comes into contact with the vertical frame portion 22 erected on the seedling placing stand 3 and the position thereof is regulated, and before the slide movement is stopped, the operating tool 21 of the interlocking member 20 is moved. The interlocking member 20 is pulled rearward and upward by abutting and locking to the end of the partition wall 10 of the seedling rest 3, and accordingly, the locking locking member 18 resists the urging force of the spring 19. And the shutter 16 is released from the locked state. Then, each of the shutters 16, 16 swings and opens downward due to the weight of the seedling, and the seedling attempts to move onto the seedling mounting table 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 shutters 16 and 16 are integrally rocked and opened at the same timing by the action of the connecting tool 17, so that the seedlings on both sides of the intermediate partition portion 14 are supplied almost simultaneously. Then, when the seedling supply box 8 is pulled out with the shutters 16 and 16 lying down, the connecting tool 17 comes into contact with the intermediate partition wall 13 of the seedling rest 3 and the connection point with one of the shutters 16 is centered. It swings in the left-right direction, the lock with the shutter 16 on the other side is released, and together with the shutter 16 on the connection side,
It can be removed by passing between the intermediate partition wall 13 and each of the partition walls 10.
