[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a seedling table of a transplanter.

[0002]

2. Description of the Related Art Conventionally, a technique of arranging a seedling feeding roller below a central portion of a seedling mounting table in a seedling mounting table of a transplanting machine such as a rice transplanter to ensure the seedling feeding is known. is there. As shown in FIG. 14, the upper surfaces of the seedling placing plate 1 disposed on the upper part of the seedling placing stand, the seedling feeding belt 2 in the middle part, and the guide plate 3 provided on the lower part are arranged on the same plane. It is.

[0003]

[Problems to be Solved by the Invention] When the seedling mounting plate, the seedling feeding belt, and the guide plate are arranged on the same plane as in the related art, the seedling mounting plate and the seedling The gap between the feed belt and the guide plate, especially when the tension is configured on the roller that supports the seedling feed belt on the seedling placement plate side, to prevent interference between the seedling placement plate and the seedling feed belt. Therefore, when the seedlings are fed, the seedlings may fall into or be caught in the gaps, and there is a problem that the seedling feeding becomes uncertain.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. In the seedling mounting table of the rush transplanter, the seedling mounting plate 1, the seedling feed belt 2, and the guide plate 3 are sequentially arranged from above,
In a side view, the upper surface of the seedling placing plate 1 is higher than the upper surface of the seedling feed belt 2, and the upper surface of the seedling feed belt 2 is arranged at a position higher than the upper surface of the guide plate 3.

Is a plan view of a guide plate of the present embodiment, and FIG. 14 is a side sectional view of a conventional seedling mounting table.

Referring to FIG. 1, the overall structure of the blast transplanter will be briefly described. A working machine mounting device B is attached to the rear end of the traveling vehicle A, and a planting device C is detachably mounted at the rear end. The planting mission case 10 of the planting device C is attached to the rear end of the working machine mounting device B. A chain case 11 is fixedly provided, and a chain case 11 is protruded rearward from the planting mission case 10.
At one rear end, a planting arm 12 is provided.
The seedlings are cut and planted by a fixed amount by the rotation of. A float 1 is located below the planting mission case 10.
3 are disposed, and the seedling mounting table D of the present invention is disposed above.

[0007] As shown in FIGS. 2 and 3, the structure of the seedling mounting table D is provided with ribs 6, 6.・ The seedling resting plate 1, the bottom plate 9, and the guide plate 3 are sequentially fixed from the top to the back side in the horizontal direction,
A seedling feed belt 2 is provided so as to wind around the bottom plate 9, a rail portion 3 a is formed on the lower surface of the guide plate 3, and a seedling stand rail 14 fixed on a planting mission case 10.
Is fitted.

As shown in FIG. 4, when the rib 6 is formed as a hat-shaped rib 6 'with a flange, the flange 6a is fixed to the bottom plate 9 by rivets 7,7. When the seedling feeding belt 2 is arranged between the rib 6 'and the rib 6', the width between the ribs 6 'and 6' becomes wider than the width of the seedling feeding belt 2, so that the seedlings are lifted. At the time of vertical feeding, the roots of the seedlings were caught on the rivets 7 and the seedling feeding was insufficient, and the lack of stock was likely to occur. Therefore, in the present embodiment, as shown in FIG. 5, the rib 6 can be formed only by cutting a rectangular tube formed by extruding aluminum, thereby reducing the weight and cost. The bottom surface of the rib 6 of the rectangular tube is formed in a step shape, the seedling mounting plate 1 is fixed to the upper bottom surface 6b, the bottom plate 9 is fixed to the central bottom surface 6c, and the guide plate 3 is fixed to the lower bottom surface 6d. Then, they are fixed with bolts and screws 15, respectively. Therefore, the seedling feed belt 2 can be arranged in the entire width between the ribs 6, and the seedlings do not protrude from the seedling feed belt 2, so that the seedlings can be sent reliably. As shown in FIG. 6, the rib 6 can be formed by bending an aluminum plate into a "u" shape to form a rib 6 ". In this case, too, the seedling feeding belt 2 is connected to the rib 6" and the rib 6 ". , And can be arranged simply and inexpensively.

As shown in FIG. 3, an upper guide rail 16 is fixed to the rear surface of the seedling mounting plate 1, and a support 17 of the tension roller 4 is fixed to a lower portion of the rib 6, as shown in FIG. As shown in FIG.
Are fixedly mounted, a drive shaft 20 is pivotally supported by the support 19, and drive rollers 5, 5... Are fixed on the drive shaft 20 between the support 19 and one end of the drive shaft 20. A drive arm 22 is externally fitted via a one-way clutch 21. The drive arm 22 is connected to a drive shaft of a fork for scraping a seedling.

A seedling feeding belt 2 is wound between the tension roller 4 and the driving roller 5, and the seedling placing plate 1 is placed on the upper bottom surface 6b of the stepped rib 6 as described above, and is placed on the central bottom surface 6c. Since the bottom plate 9 has the guide plates 3 fixed to the lower bottom surface 6d, the height of the upper surface of the seedling feed belt 2 is lower than the height of the upper surface of the seedling placing plate 1 by L1 as shown in FIG. The upper end of the seedling feed belt 2 is located below the lower end of the seedling placing plate 1 to eliminate the gap, and the upper surface of the lower portion of the seedling feed belt 2 is configured to be higher than the upper surface of the guide plate 3 by L2. When sending it down, it will not be caught or dropped.

Further, tapered portions 5a are provided on both sides of the drive roller 5 so that the seedling feeding belt 2 does not shift laterally when the seedling feeding belt 2 is turned and rotated. However, as shown in FIG. 14, a gap E 'is formed between the guide plate 3' and the tapered portion 5a because the conventional guide plate 3 'is a linear plate. The roots were involved and a lack of stock had occurred. In the present embodiment, the guide plate 3 on the side facing the tapered portion 5a is provided with tapered portions 3b, 3b having the same shape as the tapered portions 5a, 5a of the driving roller 5, and the gap E is reduced as much as possible.
Is made smaller. Are formed in the guide plate 3 so that the position can be adjusted in the vertical direction.

A seedling mounting table D constituted by fixing the seedling mounting plate 1, the bottom plate 9 and the guide plate 3 to the rib 6 is reciprocated right and left during planting work, and is supported for reciprocating the seedling mounting table D. As shown in FIGS. 7, 8 and 9, the tip of a U-shaped seedling stand arm 8 formed between the seedling feeding belts 2 on the back surface of the seedling mounting table D is fixed across the seedling feeding belt 2. A support member 24 for receiving the slide 23 is fixedly provided at an arbitrary position of the seedling stand arm 8. The slide is inserted into a groove of a feed shaft laterally provided in the planting mission case 10, and the rotation of the feed shaft causes the seedling mounting table D to reciprocate right and left.

[0013]

[Effects of the Invention] The present invention has the following effects because it is configured as described above. That is, since the seedling placing plate, the seedling feeding belt, and the guide plate are arranged from the top and their upper surfaces are sequentially lowered, the seedlings do not get caught in the seam or fall down, and the seedlings can be smoothly fed. Therefore, the seedlings can be reliably sent downward.
