DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a seedling table provided in a riding type rice transplanter, a walking type rice transplanter and the like.

[0002]

Generally, a seedling mounting table provided on a rice transplanter has a seedling mounting surface partitioned for each row.
The mat seedling placed on the seedling mounting surface is configured to be slid and conveyed along the slope of the seedling mounting surface. However, in this case, there is a possibility that the roots on the bottom surface of the mat seedling may become slip resistance and hinder smooth seedling feeding, or the mat seedling may be tilted left and right based on variation in slip resistance or the like. Therefore, it is proposed that a plurality of guide ribs project along the conveying direction of the mat seedling on the seedling mounting surface. That is, the guide ribs support the mat seedlings in a floating manner to reduce the sliding resistance and regulate the inclination of the mat seedlings, so that the seedlings can be fed smoothly and orderly. When replenishing seedlings, there was a possibility that the mat seedlings would get caught on the upper end of the guide rib and hinder the seedling replenishment work.

[0003]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of providing a seedling mounting table which can solve these problems in view of the above-mentioned circumstances. A seedling mounting table having a divided seedling mounting surface and slidingly transporting a mat seedling placed on the seedling mounting surface along the inclination of the seedling mounting surface, wherein the mat seedling mounting surface has a matte seedling transport direction. Upon projecting a plurality of guide ribs along, the seedling mounting surface
Is a plurality of grooves along the seedling transport direction and adjacent to the grooves.
And the guide rib is provided with a
Along the direction of the convex surface, and
The upper end of Idlib, the amount of protrusion as the upper is reduced, seedlings
It has a tapered shape near the upper end of the mounting surface and is flush with the convex portion . That is, when supplying the mat seedlings from the upper end side of the seedling mounting table, the inconvenience of the mat seedlings being caught on the upper end of the guide ribs can be eliminated, and the workability of supplying the seedlings can be improved.

[0004]

Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a planting portion connected to a rear portion of a riding type rice transplanter via a lifting link mechanism 2, and the planting portion 1 is connected to a rear end of the lifting link mechanism 2. A portion holder 3, a planting portion frame 4 that is rotatably connected to the planting portion holder 3, a drive case 5 that is integrally assembled to the planting portion frame 4,
A plurality of planter cases 6 projecting rearward from the drive case 5, planting claws 7 provided on each planter case 6,
The planting section frame 4 and the drive case 5 are slidably supported left and right so as to be slidable left and right, and include a seedling mounting table 8 of a mat seedling type, and a float 9 which is provided below the planter case 6 so as to be vertically swingable. That is, when the planting unit 1 is operated, the planting claws 7 scrape the seedlings of the planting unit from the lower end of the seedling mounting table 8 and plant the scraped seedlings on the rice field, while the mat seedlings The seedling mounting table 8 to be placed is laterally fed back and forth in a reciprocating manner in synchronization with the timing of scraping the planting claws 7.

[0005] The seedling mounting table 8 is mounted on the planting section 1 in a slanting posture of front and rear height, and slides and conveys a mat seedling placed on a seedling mounting surface, which will be described later, downward and rearward along the slope. However, the inclination angle of the seedling mounting table 8 is set to be gentler toward the upper side. That is, considering the supply of seedlings from the driver's seat 10 located in front of the seedling mounting table 8, the inclination angle is set so that the height of the upper end of the seedling mounting table 8 is kept as low as possible.
Numeral 11 denotes a seedling presser for controlling collapse and lateral displacement of the mat seedlings, and numeral 12 denotes a vertical feed belt for forcibly feeding the mat seedlings vertically in synchronization with the horizontal feed reversal timing of the seedling mounting table 8.

Numeral 13 denotes a plurality of partition ribs for partitioning the seedling mounting surface for each row. Between the partition ribs 13, a resin seedling mounting plate 14 forming a seedling mounting surface for each row is assembled. Although provided, the seedling mounting plate 14 has a plurality of concave grooves 14a formed at predetermined intervals along the seedling transport direction. That is, the concave groove portion 14a reduces the sliding area with the mat seedling (the area of the convex portion 14b) to improve the sliding performance, and also functions as a reinforcing rib of the seedling mounting plate 14.

A guide rib 14c is formed on the convex surface 14b so as to protrude along the seedling transport direction. The guide rib 14c is substantially the same as the seedling mounting plate 14 except for the position of the mounting hole 14d of the vertical feed belt 12. It is formed over the entire length. The guide ribs 14c function to support the mat seedlings in a floating manner to reduce the sliding resistance and to regulate the inclination of the mat seedlings. 14e are formed. Moreover, this tapered portion 14e is
As is clear from the description, the protrusion amount decreases
And the same surface as the convex portion 14b near the upper end of the seedling mounting surface.
It has a tapered shape. As described above, when supplying the mat seedlings from the upper end side of the seedling mounting table 8, the guide ribs 14c
The mat can be replenished without being hooked on the upper end of the mat. 14f and 14g are a second taper portion and a third taper portion formed above and below the mounting hole 14d, respectively.
g is for preventing the mat seedlings from being caught on the guide ribs 14c when passing through the vertical feed position by the vertical feed belt 12.

In the structure constructed as described above, guide ribs 14c are formed on the convex portion 14b of the seedling mounting plate 14 so as to protrude the mat seedlings in a floating manner so as to reduce the sliding resistance and regulate the inclination of the mat seedlings. and although those were, at the upper end of the guide rib 14c, although the tapered portion 14e of the projection amount as the upper is reduced is formed, the tapered
The shape is a convex part near the upper end of the seedling mounting surface as shown in FIG.
14b. When the mat seedling is replenished from the upper end side of the seedling mounting table 8, the mat seedling can be prevented from being caught on the upper end of the guide rib 14c, and as a result, the workability of replenishing the seedlings can be improved.
