Abstract

PURPOSE:To supply seedings rapidly and readily by inserting a specific seedling placing tool from the top part of a dividing frame into a seeding placing stand consisting only of the dividing frame and sending seedings to the lower part of the seeding placing stand by a longitudinally transporting mechanism. CONSTITUTION:A dividing frame is equipped with a guide 7a, a seeding placing tool 6 bendable and deformable only in the vertical directions is inserted from the upper part of the dividing frame to a seedling placing stand. Seedlings are taken out downward and discharged by a longitudinally sending mechanism 8 at the bottom position of the seedling placing stand while being slid along the guide.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting section of a rice transplanter, and more specifically, a seedling placing tool such as a seedling feeding box or a seedling placing plate used for supplying seedlings, Regarding the technology to be utilized as.

[0002]

2. Description of the Related Art In conventional rice transplanters, a seedling placing table is composed of a seedling placing surface and a partition wall.
When the seedlings are replenished, the seedlings stacked on the spare seedling stand prepared separately from the seedling stand are transferred to the seedling stand surface of the seedling stand like the one disclosed in Japanese Patent No. 19 publication. It was

[0003]

According to this transfer means, the seedlings on the preliminary seedling stand are moved by shifting to the seedling placing surface, that is, by frictional sliding between the seedling placing surface and the seedlings. However, the inconvenience that the soil of the seedlings was scraped off and the vertical spacing between the seedlings was disturbed was relatively likely to occur, and therefore the seedling supply work had to be performed as carefully as possible. An object of the present invention is to make seedling supply work quick and easy by enabling seedling supply work without the above-mentioned inconvenience.

[0004]

In order to achieve the above object, the present invention has a structure in which a seedling placing table which moves reciprocally laterally with respect to a planting mechanism is composed only of a partition frame which has a missing seedling placing surface. In order to slide and guide the seedling placing tool configured to be bendable and deformable only in the up-down direction from the upper end portion of the partition frame into a pair of facing partition frames, which are configured to be fitted together. And a vertical feed mechanism for extracting and discharging the seedling placing tool fitted and supported between the partition frames downward at the lower end side position of the seedling placing table. ..

[0005]

[Operation] Since the seedling placing tool functions as a seedling placing surface of the seedling placing table, it is only necessary to insert the seedling placing instrument into the partition frame of the seedling placing table while the seedling is being placed when supplying the seedlings. As a result, it is not necessary to move the seedlings by moving them as in the conventional case, and the inconveniences caused by the scraping of the seedbed soil and the disturbance of the vertical spacing between seedlings do not occur. Moreover, since the seedling placing device is used as a part of the seedling placing table, when the seedling placing device is composed of only the seedling placing surface, it is not necessary to dispose of the seedling placing device after replenishment, When the seedling placing tool is configured in a box-like shape consisting of the seedling placing surface and the side frame members, it is sufficient to clean up only the side frame members, and the rearranging of the seedling placing tool after the seedling replenishment is performed. Unnecessary or easy. Since the seedling placing tool is bendable in the vertical direction, the downward movement direction of the seedling placing tool is bent to the anti-planting mechanism side so as not to interfere with the seedling take-out port by the downward movement by the vertical feeding mechanism. Therefore, the planting part according to the present invention can be provided with a vertical feeding function so as not to hinder the planting work.

[0006]

EFFECTS OF THE INVENTION Therefore, by constructing the seedling placing tool so that it can be bent up and down and at the bottom of the seedling placing table, seedling replenishing work can be performed while enabling good seedling planting work. It is possible to eliminate the adverse effect that the seedling planting state is disturbed due to
Moreover, the planting section of the rice transplanter, which has a great advantage that the refilling work itself is easy and easy, can be provided.

Embodiments of the present invention will be described below with reference to the drawings. Fig. 4 shows a riding type rice transplanter.
The elevating link mechanism 3 is a seedling platform, 4 is a traveling machine body, and 5 is a spare seedling box loaded on the front part of the machine body. As shown in FIGS. 1 and 2, the mat-shaped preliminary seedlings 5 are mounted in a plate-shaped seedling box (corresponding to a seedling placement tool) 6 that is composed of only the seedling placement surface. In order to be able to be bent and deformed only in the upward convex direction from the horizontal plane state on which is mounted, a large number of laterally long unit members 6a are connected by a pin 6b in a chain link-like structure, and A stop portion 6c is provided for each unit member 6a so that it can be bent in only one direction. When carrying this seedling box, it suffices to have both end portions in the longitudinal direction of the seedling box.

As shown in FIG. 3, the seedling placing base 3 which reciprocates laterally with respect to the planting mechanism 1 is constructed to have a structure consisting only of the partition frame 7 between the rows where the seedling placing surface is lacking, and a pair of facing ones are arranged. The seedling box 6 carrying the spare seedlings 5 is inserted into the partition frames 7 and 7 from the upper end of the partition frame 7 and is slidably guided downward along the partition frame 7, and ,
The seedling box 6 fitted and supported between the partition frames 7 is provided with a vertical feed mechanism 8 for extracting and discharging the seedling box 6 downward and forward at the lower end side position of the seedling placing table 3. The partition frame 7 has an inverted T-shaped cross section as shown in FIG. 2, and the rail member (corresponding to a guide) 7a is fitted with the unit member 6a of the seedling box 6 by the concavo-convex structure, and the rail portion 7a is seeded. A vertical feed mechanism 8 is formed by bending the pair of left and right sprocket members 9 engaged with the unit member 6a on the front side of the rail bending portion at the lower end of the mounting table so as to rotate by a motor (not shown). I am doing it. Then, the seedling take-out port 1 by the planting unit 1 from the point where the seedling box 6 retreats forward.
Between 1 and 2, a short seedling support surface 12 on which seedlings are temporarily slidably placed is provided. When the supplementary seedlings 5 in the seedling box 6 are replenished, a simple operation of fitting the seedling box 6 as it is from the upper end of the partition frame 7 and dropping and sliding it is sufficient. The seedling box may be configured in a box shape consisting of a bottom surface, left and right side walls, and a rear wall, and the bottom surface can be slid into and out of the left and right side walls. In this case, the bottom surface corresponds to the seedling placing tool. To do. Further, a seedling placing table provided with a horizontal frame frame for reinforcement, which connects upper end portions of the partition frames at a lower position that does not interfere with insertion and removal of the seedling placing tool, may be used.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
