BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a seedling receiving belt provided at a lower end of a seedling mounting table so that a posture of a rush seedling does not collapse when a seedling mounting table of a grass transplanter slides left and right.

[0002]

2. Description of the Related Art In a planting device mounted at the rear of a grass transplanter, a grass seedling is placed on a seedling table slidably mounted on a seedling table support rail in a laterally slidable manner, and a planting claw is rotated. Then, a certain amount of grass seedlings is gripped from the opening at the lower part of the seedling mounting table, and planted in a field. The rush seedling is divided into ribs on the seedling mounting table, and the seedling mounting table slides right and left on the seedling mounting table support rail at the lower end portion in order to sequentially send rush seedlings to the opening of the planting claw. It has a structure. However, the grass seedlings at the lower end are displaced to the left and right due to the slide of the seedling mounting table, so that not only cannot a certain amount of grass seedlings be accurately fed into the opening, but also the seedlings are damaged. Therefore, in order to suppress the displacement of the sapling at the lower end, a seedling receiving belt is fixed to the lower end of the rib of the seedling mounting table, and is wound around a roller attached to the seedling mounting support rail.

FIG. 9 is a plan view showing a mounting structure of a conventional seedling receiving belt. That is, the roller frame 6 is fixed to the lower end of the seedling support rail 5, the rollers 7L, 7R, 7.7 are pivotally supported on the roller frame 6, and the seedling receiving belt 1 is wound around the rollers. . Also, in order for the wound belt to move with the left and right slide of the seedling mounting table 2,
A part of the belt is inserted into a belt holding groove 3a formed at the lower end of the ribs 3, 3... Of the seedling mounting table 2. Further, the belt holding member 4 is inserted into the groove from the inside of the belt. A part of the seedling receiving belt 1 is clamped and fixed by the fitting, the belt pressing groove 3a and the belt pressing tool 4. The portion where the seedling receiving belt 1 is not wound between the adjacent belt rollers 7L and 7R is a seedling support rail because the rotating planting claws grip a certain amount of rush. 5 is provided with an opening 8 for a planting nail.

[0004]

FIG. 10 shows the shape of the seedling receiving belt 1 when the seedling mounting table 2 slides left and right to reach the limit position of the sliding width. That is, when the seedling mounting table 2 reaches the position, the rib 3 reaches the L position or the R position. At this time, the L position or the R position of the rib 3 is
Since it is located outside the roller 7L or 7R (close to the planting claw opening 8), the portion of the wound seedling receiving belt fixed to the rib 3 is outside the belt winding locus of the roller 7L or 7R. Position. That is,
The moving distance La between the L position and the R position of the rib 3 is longer than the roller pitch Lb between the rollers 7L and 7R. Therefore, in the seedling receiving belt 1, the rib 3 is L
Alternatively, the length should be set to allow for the difference in the position between the belt fixing portion and the belt roller 7L or 7R at the R position. However, when the seedling mounting table 2 is moving within the limit position of the left and right slide, that is, when the rib 3 is moving between the rollers 7L and 7R, the seedling receiving belt 1 has a long winding locus. Is shorter than the belt length in FIG. Therefore, as shown in FIG. 9, the seedling receiving belt 1 is in a slack state (FIG. 9 is a state in which the seedling mounting table 2 is moving to the left), and the slack portion X is locally This may cause the belt to break when hitting other members.

This is for clamping and fixing the tilt 1 .

[0006]

When the seedling platform 2 of the grass transplanter slides left and right on the seedling platform support rail 5, the seedling platform 2 reaches the horizontal sliding limit position, and the rib 3 reaches the left / right limiting position L or R position. Sometimes, only the belt fixing portion 1a is pulled with respect to the belt fixing portion outside the right and left end rollers 7L and 7R, and the belt main body is not pulled much. Therefore, there is no difference in the length of the winding locus of the belt between when the rib 3 is moving between the rollers 7L and 7R, and no slack occurs.

The overall structure of the grass transplanter will be described with reference to FIG. The grass transplanter has a planting device B mounted on the rear part of a traveling machine A that travels with front and rear wheels so as to be able to move up and down. B is driven. In the planting device B, the seedling mounting table 2 is mounted on the seedling mounting table support rail 5 so as to be slidable left and right, and a transmission case for the planting device located at the front of the seedling mounting table 2 below. More specifically, the chain case 9 protrudes rearward, and the planting claw 10 is rotatably attached to the chain case 9. In the seedling mounting table 2, the ribs 3.3
... are provided in parallel, and the rush seedlings P are placed on the ribs 3 by dividing into the number of planting strips. The planting nail 10
During rotation, a claw is inserted into the planting claw opening 8 formed on the seedling mounting table support rail 5, the grass seedling P located at the opening 8 is gripped, and the plant is rotated downward along the guide. Then, the seedlings are planted on a field. In addition, the fork shutter claw 12 projecting upward below the seedling mounting table 2 is a member for separating a certain amount of seedlings into a strip shape.
Is a member for leveling the field before planting the seedlings.

The seedling receiving belt 1 is interposed between the lower end of the rib 3 of the seedling mounting table 2 and the seedling mounting table support rail 5, and the rush seedling P
When the seedling platform 2 is slid left and right, the lower end of the grass seedlings P is rubbed against the seedling platform support rails 5 to prevent the position from shifting. As shown in FIG. 5, the shape of the seedling receiving belt 1 is a ring-shaped belt made of a rubber material or the like, and the same member or another flexible member such as urethane rubber. The belt fixing portion 1a having a fitting hole is heat-welded. Alternatively, in order to further increase the strength of the belt, as shown in FIG. 6, the belt fixing portion is formed by bending a part of one outer ring-shaped belt 1b to form the inner ring-shaped belt 1b.

With this configuration, the seedling receiving belt 1 moves left and right while receiving the lower end portion of the germ seedlings, and conveys a certain amount of rush seedlings sequentially to the planting claw opening 8 together with the left and right sliding of the seedling mounting table 2. Things.

The seedling receiving belt 1 according to the present invention has a structure in which a belt fixing portion 1a fixed to the belt is sandwiched and fixed by a belt holding groove 3a of a rib 3 and a belt holding member 4. ing. With this structure, when the seedling mounting table 2 reaches the left-right movement limit position and the rib 3 reaches the L or R position in FIG. 2, the position of the rib 3 is located outside the roller 7L or the roller 7R. But FIG.
(Shown when the rib 3 reaches the R position)
Even when the belt fixing portion 1a is pulled by the rib 3, the main body of the seedling receiving belt 1 is hardly pulled outward and the winding locus hardly changes. Therefore, even when the rib 3 moves between the rollers 7L and 7R in FIG. 7, the seedling receiving belt 1 hardly loosens. That is, conventionally, the seedling receiving belt 1 itself is
The belt body is pulled out together with the ribs 3 when the ribs 3 reach the L position or the R position. When the ribs 3 are located between the rollers 7L and 7R, the length of the belt winding locus greatly differs from the length of the belt winding locus, causing slack. However, the seedling receiving belt 1 according to the present invention has this problem. Is eliminated.
This operation and effect can be obtained also by the seedling receiving belt having the shape shown in FIG.
