Description

[Detailed Description of the Invention] The present invention includes a main seedling stand that moves back and forth horizontally with respect to the machine body;
The present invention relates to a seedling replenishing device for a rice transplanter, which is equipped with a spare seedling stand that is fixed in position relative to the machine body, and supplies seedlings on the spare seedling stand to the main seedling stand in a stopped state.

Conventionally, the seedling replenishment device of this type of rice transplanter was
There is a device described in Publication No. 0-135629, in which a spare seedling stand is fixed in position relative to the machine body, and only the main seedling stand is moved back and forth horizontally, in order to prevent the balance of the machine body from being greatly disturbed from side to side. In order to reduce the weight of the thing that moves back and forth horizontally with respect to the machine, we stop the horizontal back and forth movement of the main seedling stand and replenish seedlings from the spare seedling stand to the main seedling stand. In order to receive the seedlings supplied from the spare seedling stand, it is necessary to align the horizontal position of the main seedling stand with the spare seedling stand, and the horizontal position of the main seedling stand must be The disadvantage is that the position adjustment is very complicated.

In view of the above-mentioned circumstances, an object of the present invention is to eliminate the troublesome task of aligning the stop position with the seedling replenishment position from the spare seedling rack when stopping the main seedling rack that is moving back and forth laterally for replenishing seedlings. The object of the present invention is to provide a seedling replenishing device for a rice transplanter that does not require extensive work.

A characteristic configuration of the present invention is that, in the seedling replenishing device of the rice transplanter mentioned above, a relay supply table is provided that once receives the seedlings from the preliminary seedling tray and then supplies them to the main seedling tray, and the seedling tray is placed in the seedling tray. is provided so as to be movable in the lateral direction of the machine, so that the seedling receiving and placing surface of the relay supply table is connected to a predetermined seedling placing surface of the preliminary seedling placing table, and a predetermined position of the main seedling placing table where seedlings are to be supplied. The structure is configured such that the position can be changed between the positions connected to the seedling placement surface.

The effects of the characteristic configuration of the present invention are as follows.

In other words, in order to be able to connect the seedling receiving surface of the relay feeding table to the seedling placing surface of each of the preliminary seedling placing table and the main seedling placing table, the preliminary seedlings can be placed on the main seedling placing table. Although it is possible to slide the seedlings and feed the seedlings easily, when the main seedling stand that is moving back and forth horizontally is stopped to feed the seedlings,
Even if the main seedling tray deviates from the desired position for supplying seedlings with respect to the spare seedling tray, since the relay supply table moves in the lateral direction of the machine, the preliminary seedling tray It is possible to move the bacteria on the relay supply stand, which has once been received, laterally to the supply position to the main seedling stand.In other words, the seedlings can be transferred from the preliminary seedling stand to the main seedling stand. To replenish the seedlings, first transfer the seedlings to the horizontally movable relay supply stand, and then replenish the seedlings from the relay supply stand to the main seedling loading stand.
The misalignment of the main seedling rest with respect to the preliminary seedling rest can be absorbed by the lateral movement of the relay feeding stage, and as a result,
The difficult and complicated operation of stopping the main seedling rack at the seedling supply position with respect to the preliminary seedling rack is completely unnecessary, and the operator can freely place the main seedlings at a convenient time. This allows the seedlings to be replenished by stopping the platform.

Embodiments of the present invention will be described below based on illustrative drawings.

The figure shows a riding-type rice transplanter for planting four rows, and a seedling planting device 3 is connected to the rear of the machine, which is equipped with rear propulsion wheels 1, 1 and front steering wheels 2, 2 that can be raised and lowered. The rear propulsion wheels 1, 1 are raised and lowered according to the depth so that the seedling planting device can be positioned at a desired height.

The seedling planting device has four sets of swing link type planting mechanisms 4.
...w are arranged in series, and four seedlings arranged in a mat shape are placed side by side in front of the main seedling surface 5', which moves back and forth in the horizontal direction with a constant stroke. The table 5 is arranged at an angle.

Further, above the main seedling rest 5, a spare seedling rest 6 equipped with a seedling mounting surface 6' for placing and accommodating spare seedlings is positioned, and a support frame A extending from the machine body side is installed. , A is used to support and fix the position of the preliminary seedling stand 6 relative to the machine body.

Further, at the front part of the upper end of the main seedling resting stand 5, there is provided a seedling receiving mounting surface 9' for supplying seedlings to the main seedling resting stand 5 after once receiving the seedlings from the preliminary seedling resting stand 6. Relay supply stand 9
, and the relay supply stand 9 is placed on both support frames A.
, is supported by a guide rod B which is suspended horizontally at the front end of A, so as to be able to swing vertically.

The relay supply table 9 is configured so that when it is swung upward, its swinging end comes into contact with the front end of the preliminary seedling loading table 6,
The structure is such that the seedlings on the preliminary seedling loading table 6 can be fed by sliding them onto this relay feeding table 9, and furthermore, the relay feeding table 9 holding the seedlings can be swung downward to control its swinging. The end is brought into contact with the upper end of the main seedling rest 5, so that the seedlings on the relay supply stand 9 can be slid onto the main seedling rest 5 and supplied.

Further, the relay supply table 9 is configured to be able to slide and move laterally along the guide rod B, and is configured to be able to slide and move laterally along the guide rod B.
The structure is such that the seedlings from the main seedling stand 5 for planting in multiple rows can be supplied to any of the rows by horizontally moving the seedlings in the inherited state.

In addition, the relay supply table 9 is arranged as shown in FIGS. 2 and 3.
If the width is smaller than the width on which a row or two rows of seedlings can be placed, that is, the width of the main seedling rest 5 during which the seedlings are being placed, even when the relay feeding stand 9 is moved laterally, the relay feeding stand 9 does not protrude significantly to the sides of the fuselage.

Further, the preliminary seedling stand 6 may be provided with a plurality of upper and lower seedling support shelves so as to be able to accommodate a large amount of bacteria.
