Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is equipped with a plurality of stages of spare seedling mounts at the rear of a driver's seat in a rice transplanter machine, and blocks for each planting row from the ridge side. The present invention relates to a preliminary seedling accommodation device for a rice transplanter configured such that the preliminary seedlings placed and supported by the support member can be slide-transferred onto the preliminary seedling placement table in a row.

[Conventional technology]

As the above-mentioned preliminary seedling accommodation device, for example, as shown in Japanese Utility Model Publication No. 62-204411, the upper preliminary seedling mounting table is composed of a pair of front and rear support rails, and each support rail is provided in a fixed state. There was something.

[Problems to be Solved by the Invention]

The conventional structure described above is designed so that the spare seedlings can be transferred from both the left and right sides and that the spare seedlings can be stably placed and supported.

However, in the above-mentioned conventional structure, when supplying the seedlings of the seedling planting device with the spare seedlings, when supplying the spare seedlings on the upper stage side, it is possible to smoothly perform without any obstacles. When supplying seedlings, there was a drawback in that the front side support rails of the upper preliminary seedling mounting stand interfered with the seedling supply work and made the work difficult.

The present invention has an advantage that the preliminary seedlings can be slide-transferred in a row form, but an object thereof is to eliminate the above-mentioned problems.

[Means for Solving the Problems]

A feature of the present invention is that in the preliminary seedling accommodation device of the rice transplanter having the above-mentioned configuration, a pair of front and rear support rails along the transfer direction of the preliminary seedling mounting table are provided, and operation in the preliminary seedling mounting table on the upper stage side is performed. The seat side support rail is configured to be freely positionable between a regular seedling support position and a retracted position that opens the front side upper side of the lower stage spare seedling, and its action and effect are as follows. On the street.

[Work]

That is, when the seedlings are transferred to the slide and the seedlings are placed and supported, the support rails on the driver's seat side are set to the regular support positions so that the seedlings are stably supported by the pair of support rails. be able to. Then, when supplying the seedlings placed on the lower side to the rear seedling planting device, by setting the support rail continuously extending in the sliding direction to the retracted position, the worker The part where the hand is inserted to operate the front part is largely opened, which facilitates the work.

〔The invention's effect〕

Therefore, according to the present invention, while having the advantage that a plurality of blocks of spare seedlings corresponding to the planting section of the rice transplanter can be efficiently slide-transferred in a row, at the time of the seedling supply work on the lower stage side. There were no obstacles and it was possible to work efficiently.

〔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 the preliminary seedling accommodation device (A) according to the present invention. This rice transplanter is a seedling planting device (3) for planting a plurality of rows through a link mechanism (2) that swings up and down by a hydraulic cylinder (1) at the rear of a riding type traveling body.
Are connected. The seedling planting device (3) is for placing seedlings for planting and moving back and forth with a constant stroke in a rearward and downward inclined posture. The seedling placing table (4) is placed below the seedling placing table (4). It consists of a seedling planting mechanism (5) and a grounding float (6) for cutting out and planting each plant.

A rear seedling storage device for storing spare seedlings for replenishing the seedlings that have been planted and are decreasing at a position behind the driver's seat (7) of the machine body and above the front of the seedling mounting base (4). (A)
Have been deployed. Hereinafter, the configuration of the preliminary seedling accommodation device (A) will be described in detail.

As shown in FIG. 2, the rear part of the machine is equipped with upper and lower two stages of spare seedling mounts (8) and (8), and seedlings which are an example of a supporting member for each block of each planting row from the ridge side. The preliminary seedlings (W) placed and supported on the scooping plate (9) can be slide-transferred onto the preliminary seedling placement tables (8) and (8) in a row form.
That is, a pair of left and right vertical frames (11), (11) are erected up and down from the body frame (10), respectively, and a pair of front and rear extending in the left-right direction is provided at the upper ends of the vertical frames (11), (11). The support rails (12a), (12b) are fixed to form the lower side preliminary seedling mounting table (8), and the laterally-viewing U-shaped connecting frame (13) is laterally spaced at appropriate intervals.

b) and (12b) are formed so that the upper part has an arc shape and the lower surface has a flat shape.

As shown in FIG. 1, the seedling scooping plate (9) is formed with a chevron-shaped projecting bent portion (9a) near one end, and this bent portion (9a) is attached to the front side. The support rail (12a) is configured to be slid and transferred while being engaged with the support rail (12a), and the movement of the seedling scooping plate (9) in the front-rear direction is restricted. Further, a long hole (14) for facilitating holding is formed in the grip portion (9b) further on the end side of the bent portion (9a).

As shown in FIGS. 1 and 3, the front side support rail (12
A storage member (15) for storing the seedling scooping plate (9) after the preliminary seedling supply is detachably connected to the lower surface of the middle part of a). That is, the U-shaped mounting bracket (16) is fixed to the lower surface of the support rail (12a), and the storage member (15) made of a bar material is formed into a U shape so that the elongated hole (14) can be inserted therethrough. Attach the flat end to the bracket (1
It is bolted to 6) so that it can be removed from the lower side.

Then, the front side of the upper seedling stand (8), that is, the support rail (12a) on the driver's seat (7) side, is set at the regular seedling support position and in front of the lower seedling (W). The position can be freely changed to a retracted position where the upper part side is opened. More specifically, as shown in FIG. 1, the side portions of the plurality of connecting frames (13) are swingable around the horizontal axis (P ₁ ) intermediate between the front and rear support rails (12a) and (12b). The rocking member (7) is pivotally supported, and the front support rail (12a) is fixed to the rocking end of the rocking member (17). The swing member (1
