Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a preliminary seedling that is provided in the upper front of a seedling planting device equipped with a rearward-declining tilted seedling placement table and places a preliminary seedling on each. The present invention relates to a preliminary seedling accommodating device for a rice transplanter, which is provided with mounting supports in a plurality of upper and lower stages relative to a fixed frame.

[Conventional technology]

As the above-mentioned accommodating device in the related art, for example, Japanese Utility Model Publication No. 58-4
As shown in Japanese Patent No. 1790, a spare seedling stand as a plurality of spare seedling placement supports is integrally mounted on a bracket, and the entire storage device is rotated around the horizontal axis with respect to the machine body. There was a structure that supported it so that it could be adjusted dynamically.

[Problems to be solved by the device]

The above-mentioned conventional structure is designed to rotate the storage device in the backward descending posture and push the preliminary seedling from the control unit side to slide it to transfer the seedling onto the seedling mounting table, but a large weight spare The operation and holding mechanism is required to hold the whole seedling storage device in a predetermined backward tilted position, which is disadvantageous in that it requires a large-scale structure. Since they are constructed as close to each other as possible and have a short height, there is an adverse effect that the auxiliary seedling stand on the upper side interferes with the work when the seedling on the lower side is supplied.

An object of the present invention is to eliminate the above disadvantages.

[Means for Solving the Problems]

The feature of the present invention is that, in the preliminary seedling accommodation device of the rice transplanter having the above-described configuration, at least the preliminary seedling mounting support on the upper side is vertically rocked around the horizontal axis at the rear side position of the preliminary seedling mounting support. It is movably attached to the fixed frame, and its action and effect are as follows.

[Action]

In other words, when transferring the seedlings on the seedling table from the state where the seedlings are stored and stored, the upper seedlings are pushed toward the seedling table and slide-transferred, and then the lower seedlings are supplied. In this case, by swinging the upper stage preliminary seedling placement support upward around the rear horizontal axis, the front upper side of the lower stage preliminary seedling is largely opened, and seedling supply becomes extremely easy.

[Effect of device]

As a result, it becomes easy to perform the work of supplying the lower-stage spare seedlings to the seedling mounting table, and a large-scale holding mechanism for rotatably supporting the entire spare seedling accommodation device is not required. It can be constructed with a simple structure in which it can be individually rocked.

〔Example〕

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

FIG. 4 shows a riding type rice transplanter equipped with a preliminary seedling accommodation device (A) according to the present invention. This rice transplanter connects a multi-row planting type seedling planting device (2) to the rear part of the riding type traveling body (1), and is located in front of and above the seedling planting device (2). The spare seedling storage device (A) is provided behind the driver's seat (3).

The seedling planting device (2) is configured to include a seedling platform (4) in which the seedlings for planting are placed in a rearwardly inclined posture, a planting mechanism (5) for cutting and planting seedlings one by one. , And is linked to the rear part of the machine body (1) via a link mechanism (6) so as to be capable of being driven up and down.

The spare seedling accommodation device (A) has three upper and lower stages of spare seedling placement sections (7a), (7b), (7c) for placing and storing the spare seedlings (W) respectively.
And each of the spare seedling placement parts (7a), (7b), (7c)
Each has a spare seedling support (8) for placing a spare seedling. Each of the spare seedling placement supports (8) is supported by a fixed frame (9) standing upright from the machine body (1), and the spare seedling placement support (8) is spared from the ridge side. It is configured so that the seedlings can be transferred in a slide form in a row.

That is, the block-shaped seedlings corresponding to each planting row are placed in rows on the seedling scooping plate (10) for each block from the ridge-side seedling supply device (not shown) to the seedling scooping plate (10). At the same time, the seedlings are transferred to the support bodies (8) of the preliminary seedling placement portions (7a), (7b), (7c) in a row form.

On the lower surface of the seedling scooping plate (10), there are provided engaging pieces (11), (11) which engage with the support plate (8) and can prevent the sliding down after the preliminary seedling is supplied. .

And the spare seedling placement parts (7a), (7b) on the upper and middle stages
The support body (8) is configured to be swingable upward around the rear horizontal axis (P ₁ ) and (P ₂ ).

That is, as shown in FIG. 1 and FIG. 2, the support bodies (8) of both the preliminary seedling placing portions (7a) and (7b) are connected to the horizontal axis (P ₁ ),
(P ₂ ) can swing up and down freely in the laterally extending portion (9
It is pivotally connected to a), and both supports (8) are configured to be received and supported by the upper surface of the laterally extending portion (9a) in a horizontal posture.

According to this structure, it suffices to swingably support the support body (8) with respect to the frame (9), and a large-scale mechanism such as adjusting the inclination angle of the seedling supply posture is not required and the structure is simplified. It can be converted. In other words, when transferring the spare seedling (W) in the mounted state onto the seedling mounting table (4) of the seedling mounting mounting (2), the seedling mounting device (2) is raised to raise the seedling mounting base. (4)
The upper end of one of the spare seedling placement parts (7a), (7b), (7
After setting to the state of being connected to the rear end of the support (8) of c),
The preliminary seedlings (W) are extruded and slide-transferred. Here, when supplying the lower side preliminary seedlings (W), as shown in FIG. 2, the support (8) of the upper side preliminary seedling placing portion (7a) is slightly moved in the upward swinging position. The support (8) of the preliminary seedling placement section (7b) on the middle stage side is kept swinging upward with one hand while the position is maintained in the forward tilted posture, and the lower stage preliminary seedling (with the other hand ( W) can be extruded and supplied.

[Other Embodiments] The support bodies (8) of the preliminary seedling placement portions (7a), (7b), (7c) may be configured by a pair of support rails, respectively.

All the support bodies (8) of the preliminary seedling placement portions (7a), (7b), (7c) may be provided so as to be swingable upward.

The preliminary seedling placement support (8) is not limited to the upper and lower three-stage structure, and can be applied to two or more stages.

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