Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seedling supply structure in a rice transplanter.

[Conventional technology]

As the above-mentioned supply structure, conventionally, a pair of upper and lower flat plate-shaped spare seedling mounts for accommodating the spare seedlings are arranged on the upper part of the seedling mount in the backward descending position, and each spare seedling mount is provided at the front end. The seedlings are pivotally supported on the seedling planting device side, and the seedlings are kept in a substantially horizontal position. The seedlings are tilted downward and connected to the upper part of the seedling stand. There was a configuration in which the seedlings could be supplied efficiently by switching freely between the seedling supply state and the seedling supply state.

[Problems to be solved by the device]

However, in the above-mentioned conventional structure, when the seedlings on the spare seedling mounting table are slid part way, if the aircraft approaches the edge and wants to supplement the spare seedling mounting table with the spare seedlings, a seedling scooping plate is used. Even if the seedlings were taken out, there was a drawback that the seedlings could not be transferred to the seedling placing table because they would be caught by the spare seedling placing table.

Then, as shown in FIG. 5 and FIG. 6, the structure which formed the recessed part (12) through which a seedling can pass was considered on the rocking | swiveling side of a preliminary seedling mounting base (7b).

However, even with the above-mentioned improved structure, the inclination angle of the seedling supply state of the auxiliary seedling stand on the lower side is smaller than that on the upper side, the slide guide performance of the seedlings is not sufficient, and the smooth transfer of the seedlings is not achieved. It had a drawback to be improved that it could not be loaded.

The present invention aims to eliminate the above disadvantages.

[Means for Solving the Problems]

The feature of the present invention is that, in the upper front part of the machine of the seedling planting device, two front and rear stages of the spare seedling mount which are pivotally supported by the front part of the device are swingable, and both spare seedling mounts are respectively In the downward swinging posture,
The seedlings placed via the seedling scooping plate are configured to be slidable on the seedling mounting table in the seedling planting device, and a concave section through which the seedlings can pass is formed on the swinging end side of the auxiliary seedling mounting table on the lower side. In addition, a guide roller whose position can be freely changed is attached to the preliminary seedling mounting base over the working posture of the seedling scooping plate projecting above the seedling mounting surface and the storage posture retracting from the recess (12). There are certain points, and the actions and effects are as follows.

[Action]

That is, when supplying the preliminary seedlings to the seedling mounting table, first, the lower seedling mounting table is tilted to supply the seedlings, and then the upper seedling mounting table is tilted and supplied. When supplying the lower stage preliminary seedlings, the guide roller is set to the working posture, and the seedlings can be smoothly slid from the lower stage preliminary seedling mounting table to the seedling mounting table having a small inclination angle.

Moreover, if the aircraft approaches the edge of the ridge and the lower seedlings can be transferred halfway and you want to replenish the lower seedlings with auxiliary seedlings, set the guide rollers to the storage posture and then scoop the seedlings. When the plate is pulled out toward the front, the spare seedlings are transferred to the seedling mounting table through the recesses, and the spare seedling mounting table can be reset to the seedling mounting table posture.

[Effect of device]

Therefore, according to the present invention, it is possible to efficiently place the preliminary seedlings in a small space by using a two-tiered structure,
It is possible to smoothly transfer the spare seedlings onto the seedling mounting table, and it becomes possible to supply the spare seedlings even when the amount of seedlings reduced is relatively small, thus improving work efficiency. It became a thing.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows the rear part of the riding type rice transplanter according to the present invention. This rice transplanter is configured by connecting a seedling planting device (3) to a rear portion of a riding type traveling body (1) via a link mechanism (2) so as to be able to move up and down.

The seedling planting device (3) cuts out one by one a seedling stand (4) in a backward descending posture for placing seedlings for planting and seedlings provided under the seedling stand (4) one by one. It consists of a seedling planting mechanism (5) for planting on the paddy field, a grounding float (6), etc. Above the front of the seedling planting device (3), there are two upper and lower reserves for accommodating spare seedlings. Seedling stands (7a) and (7b) are provided.

The seedling mounting table (4) is located below the rear seedling mounting table (4a) having a steep slope and the preliminary seedling mounting tables (7a), (7b), and the front seedling mounting table (4b) having a gentle slope. The rear seedling placing table (4a) is configured so that the inclination angle is always constant, and the front seedling placing table (4b) is configured to be swingable up and down around the rear end horizontal axis (P). However, a sliding roller (8) for smoothing the movement of the seedlings is provided at the connecting portion between the two stands (4a) and (4b).

As shown in FIG. 2 and FIG.
a) and (7b) are a preliminary seedling mounting position in which the front part is pivotally supported by the support frame (9) and is locked by the locking member (10) that can be retracted and maintained in a substantially horizontal posture, and the rear part. Is configured to be freely swingable to a seedling feeding position where the seedling placing table (4) swings downward to the upper surface, and at the seedling feeding position, the seedlings (W) placed via the seedling scooping plate (11) are placed. It is configured so that it can be slide-transferred onto the mounting table (4). The support frame (9) is fixed to the front seedling mounting table (4), and these are integrally provided so as to be rotatable and adjustable around the shaft core (P), depending on the type of seedling and the ease of sliding. The angle can be initialized.

As shown in FIG. 1, a recess (12) through which the seedling (W) can pass is formed on the swinging end side of the auxiliary seedling stand (7b) on the lower side, and seedlings of the seedling scooping plate (11) are formed. A guide roller (13) whose position can be freely changed between a working posture projecting upward from the mounting surface (11a) and a storage posture retracting from the recess (12).
Is attached to the spare seedling stand (7b).

More specifically, the support brackets (15) and (15) fixed to the lower surface sides of the protrusions (14) and (14) on both sides of the recess (12) of the preliminary seedling stand (7b) are supported respectively. A shaft (16) is installed and a plurality of guide rollers (13) are attached to the support shaft (16). On the other hand, an insertion hole (17) is formed in the seedling scooping plate (11) at a position corresponding to the roller, and the guide roller (13) is inserted so as to project from the seedling placement surface (11a). In addition, an elongated hole (18) extending in the front-rear direction is formed in each of the support brackets (15) and (15), and the support shaft (16) is formed into the elongated hole (1
