Description

[Detailed explanation of the invention] Generally, in a rice transplanter, when the seedlings (mat-shaped seedlings) placed on the main seedling stand are planted and there are few remaining, the rice transplanter replenishes the seedlings with spare seedlings. As a device,
A main seedling resting stand tilted forward is arranged in front of the operating handle extending rearward, a spare seedling resting stand is arranged near the top of the main seedling resting stand, and the spare seedling resting stand is placed in a forward position. It can be freely swung up and down around the horizontal axis, and can be freely switched between a preliminary seedling placement and accommodation posture and a seedling supplying posture in which the lower end of the preliminary seedling tray overlaps the upper end of the main seedling tray. In addition, an operating lever for changing the posture of the preliminary seedling rest is extended to the control handle side of the preliminary seedling rest, so that the posture of the preliminary seedling rest can be changed by operation from the control section. Previously, a device has been proposed in which the preliminary seedlings on the preliminary seedling rack can be pulled out from the control section and transferred to the main seedling rack.

According to this seedling supply device, when the spare seedling rest is switched to the seedling supply position, the spare seedling rest is overlapped with the upper end of the main seedling rest, so that the main seedling rest is transferred from the spare seedling rest to the seedling rest. This makes it easy to move the spare seedlings smoothly when dragging them out onto the table.

However, in the past, the width of the preliminary seedling rack was set to be the same as the width of the seedlings, so it was not possible to feed the seedlings smoothly due to the sliding resistance caused by the side stems. There was an inconvenience that it was not easy to load seedlings.

Therefore, it is conceivable to make the width of the preliminary seedling rack wider than the width of the seedlings to reduce the sliding resistance when replenishing the seedlings, but in such a case, the side frame of the preliminary seedling tray and the seedlings This creates a gap between the seedlings and the sides, causing the inconvenience of the seedlings moving from side to side.

The present invention is a seedling replenishing device for a rice transplanter that can smoothly replenish seedlings as described above, so that seedlings can be easily loaded into the spare seedling rack and seedlings can be conveniently replenished into the main seedling rack. The aim is to improve the preliminary seedling stand.

A feature of the seedling replenishing device of the rice transplanter of the present invention is that the side frame of the preliminary seedling rest is formed into an outwardly expanding inclined surface, and the height of the side frame is adjusted to the upper part of the seedling bed. This structure is set to be smaller than the thickness, and this structure provides the following effects.

That is, since the sides of the side frame of the stand for preliminary seedlings are formed into outwardly expanding inclined surfaces, the width of the stand for preliminary seedlings can be made to be the same width as the width of the seedlings. It is possible to easily load seedlings into the stand for extra seedlings, and to prevent the placed seedlings from moving laterally. In this case, a triangular space is formed between the side of the side frame of the stand for preliminary seedlings and the side of the placed seedlings, and as time passes, the placed seedlings may move laterally due to the vertical vibration of the machine. This causes the inconvenience that the seedlings cannot be smoothly fed from the preliminary seedling rack to the main seedling rack because the seedlings spread to the side frame and adhere to the side frame. Because it is designed to be smaller than the thickness of the part,
There is little sliding resistance due to the lateral stems, making it easy to supply seedlings smoothly.

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

The figure shows a pair of left and right propellers in contact with a hard surface that propels the aircraft, which consists of a front engine 1, a rear seedling planting device 2, and a control handle 3 connected rearward and upward from near the seedling planting device 2. This figure shows a walking-type rice transplanter that moves while being supported at an appropriate height in a field by the cooperation of wheels 4, 4 and three floats 5 arranged in parallel in the horizontal direction that slide on the field.

The seedling setting device 2 includes a main seedling resting stand 6 which is tilted forward and tilted forward and moves horizontally in a constant stroke, and a main seedling resting stand 6 which is arranged side by side in a horizontal direction that circulates up and down between the lower end of this main seedling resting stand 6 and the mud. The six planting nails 7, etc. are to be kept in mind,
One by one, block seedlings are taken out one by one along the lower end row of the mat-like seedlings W placed on the main seedling stand 6 and whose roots are connected to the floor, and 6 rows of seedlings are placed in the field. It is planned to instill

Next, when the seedlings W placed on the main seedling rest 6 are planted and there are only a few remaining, a procedure is carried out to replenish the main seedling rest 6 with spare seedlings Wa in the form of a broken mat. The seedling supply device will be explained.

That is, a preliminary seedling rest 8 is provided near the top of the main seedling rest 6.

This preliminary seedling stand 8 is rotatably supported around a horizontal axis X with respect to a pair of left and right loop-shaped support arms 9, 9 which are connected from the machine frame, and is supported by an operating lever. 10, the main seedling resting stand 6 is switched between a seedling supplying position (indicated by a phantom line in the figure) in which the lower end overlaps the upper end of the main seedling resting stand 6, and a seedling placement and storage position. ,and,
They are designed to be locked and held in their respective positions.

The main seedling resting stand 6 and the preliminary seedling resting stand 8 are constructed by processing resin into a certain shape, and are provided with side frames 6a and 8a at appropriate intervals in the lateral direction.・is in great shape.

The side frames 6a of the main seedling resting table 6 have a height H such that the seedlings W. The height h of the side frame 8a of the preliminary seedling stand 8 is set to be smaller than the thickness of the upper part of the bed of the seedling Wa, and The side surfaces of 8a... are formed into outwardly expanding inclined surfaces 8b...

In addition, in carrying out the present invention, when the preliminary seedling resting stand 8 is provided in a form that does not move laterally integrally with the main seedling resting stand 6 as shown in the illustration, the height h of the side frame 8a... This makes it possible to set the value to a low value, and it is easy to bring out the effects of the present invention.

In this case, as shown in FIG. 4, the upper part of the floor that protrudes upward from the side frame 8a tends to spread laterally due to the influence of vibration of the machine body, etc., and as a result, the main seedling stand 6
When loaded into the seedling tray, the bed soil portion can be properly received by the side frames 6a of the main seedling stand 6 without wobbling.

In addition, as in the embodiment, in the case of a configuration in which the spare seedling resting table 8 is not moved laterally integrally with the main seedling resting table 6, the horizontal position of the main seedling resting table 6 and the preliminary seedling resting table 8 must match when replenishing seedlings. However, since it is difficult to stop the seedlings in such a consistent state, it would be convenient if the preliminary seedling stand 8 was configured to be able to be moved laterally within a small range.
