Description

[Detailed Description of the Invention] The present invention relates to an auxiliary seedling stand device in a rice transplanter. Rice transplanters with an auxiliary seedling stand installed on the machine body have already been provided, but since the conventional auxiliary seedling stand was generally of a fixed type, each time when feeding and placing seedlings on the auxiliary seedling stand, it was necessary to insert pine seedlings each time. Each time the device is held in hand, it is necessary to step into the mud to carry it to the position where the auxiliary seedling stand is placed, which is a heavy burden on the worker and also causes the inconvenience of wasting a lot of valuable time in feeding the seedlings. Particularly when there is only one worker or when a large machine is used for multi-row planting, there is a drawback that the worker's labor increases and efficiency decreases.

The present invention was developed to solve the above-mentioned drawbacks, and although the auxiliary seedling stand can be fixed to the machine body in a well-balanced manner, when feeding seedlings to the auxiliary seedling stand, the auxiliary seedling stand must be placed in the field. The angle and position that are most convenient for the operator to work are adjusted according to the topography of the aircraft, and the seedlings can be easily supplied and placed from the side of the aircraft or from the rear bank or road, thereby reducing the worker's effort and labor.
It is an object of the present invention to provide an auxiliary seedling stand device for a rice transplanter that can significantly reduce the burden and reduce the time spent on seedling supply work as much as possible.

To explain the configuration of the present invention with reference to an embodiment shown in the drawings, A is a riding-type rice transplanter, and a seedling stand 3, a float 4 and a planting machine are installed at the rear of a traveling body 2 equipped with an engine 1. Planting section 6 consisting of rods 5, etc.
are connected via a link mechanism 7 so as to be able to rise and fall freely, and the power of the engine 1 is derived from the rear of the traveling body 2 through a universal joint (not shown).
The power is transmitted to the planting section 6 via the power, and the planting rod 5 moves up and down at a predetermined speed, and the pine seedlings ( Seedlings are scraped off one by one from (not shown) and successively planted on the rice field.

Reference numeral 8 denotes an auxiliary seedling stand installed in parallel with the seedling stand 3 in the vicinity of and behind the driver's seat 9. Upper and lower two-stage seedling tray 8b supported so that it can be inserted and removed freely
It is made up of. Reference numeral 10 denotes an auxiliary seedling support frame having an inverted L-shape when viewed from the side, and one end of the support frame 10 is horizontally rotatably connected to a fulcrum shaft 11 which is erected and fixed at the center of the rear part of the machine body A in the machine width direction. A pair of channel-shaped guide rails 12, 12 are provided on the upper horizontal portion 10a of the support frame 10.
It is fixed perpendicular to. 13 is a stay for reinforcing the guide rails 12, 12.

14 is a roller mounting leg fixed to the back surface of the frame 8a, and rollers 14a, 14a rotatably supported by the channel-shaped guide rails 12, 12 are pivotally supported on the roller mounting leg 14. There is.

With the above configuration, the entire auxiliary seedling stand 8 is attached to the fulcrum shaft 11
It is designed to be able to rotate in the horizontal direction about the center and to be able to slide in the longitudinal direction along the guide rails 12, 12.

Reference numeral 15 denotes stoppers provided at both ends of the guide rails 12,12. On the other hand, 16 is a fixing device for fixing the auxiliary seedling stand 8 parallel to the seedling stand 3 and at an appropriate mounting position in the machine width direction.
A locking pin 18 is attached to the upper part of a rod 17 that stands opposite to each other in front of the rod, so that the locking pin 18 can freely appear and retract in the front and rear direction.
When the auxiliary seedling stand 8 is parallel to the seedling stand 3 and at the proper mounting position in the machine width direction (the state shown in FIG. 2), the locking pin 18 is fixed to the locking plate 8a. 19 and the pin hole 10b of the support frame 10, and the locking pin 18 is fitted into the pin holes 19a, 10b by the action of a spring 20. 21 is a spring holder.

In the above-mentioned configuration, when performing the planting work, after placing pine seedlings on the seedling stand 3 and the auxiliary seedling stand 8, the traveling body 2 is advanced and the work is started. As the work progresses, the number of pine seedlings on the seedling stand 3 decreases, but before the remaining seedlings on the seedling stand are completely gone, the machine 2 is stopped and the pine seedlings placed on the auxiliary seedling stand 8 are removed. Transfer the seedlings onto the seedling stand 3. In this case, since the planting section 6 can be automatically raised from the driver's seat 9 position by manual operation, the inclined upper end of the seedling stand 3 is positioned at approximately the same height as the auxiliary seedling stand 8. By aligning the rows of the seedling stand 3 and the auxiliary seedling stand 8 as shown in Fig. 2,
It is sufficient to lift the pine seedlings together with the seedling tray 8b and simply slide the pine seedlings from the seedling tray 8b onto the seedling platform 3, and therefore the work of transferring the pine seedlings can be easily performed from the driver's seat 9.

After the seedlings have been transferred from the auxiliary seedling tray 8 to the seedling carrier 3 as described above, the planting section 6 is lowered to the ground and the planting work is continued. When the mat seedlings on the auxiliary seedling tray 8 run out and seedlings need to be replenished to the auxiliary seedling tray 8, the machine body A is moved to the bank or road a side, and the locking pin 18 of the fixing device 16 is pulled in the direction of the arrow in FIG. 3 against the spring 20, so that the locking pin 18 is locked in the locking plate 19 and the pin holes 19a, 19b of the support frame 10.
0b, the auxiliary seedling tray 8 is released from its fixed state with respect to the rotation and sliding by a single operation of the locking pin 18. Therefore, by manually rotating the auxiliary seedling tray 8 in accordance with the topography of the field, the entire auxiliary seedling tray 8 rotates horizontally around the fulcrum shaft 11, so that the auxiliary seedling tray 8 can be rotated to the angle most convenient for the operator, as shown in Fig. 5 or 6. Moreover, by drawing out the auxiliary seedling tray 8 in its longitudinal direction, the entire auxiliary seedling tray 8 can slide via the guide rails 12, 12 and the rollers 14a, 14a, so that the auxiliary seedling tray 8 can be positioned at the closest position to the seedling supply point, such as the bank or road a. Therefore, the operator can easily and quickly supply seedlings to the auxiliary seedling tray 8 from the side or rear bank of the machine body A without having to enter the mud of the field every time. At this time, either the operator or the assistant can freely rotate and slide the auxiliary seedling tray 8, so that the operation of supplying seedlings to the auxiliary seedling tray 8 can be carried out quickly and efficiently.

In this case, the auxiliary seedling stand 8 can be turned to the right or to the left around the fulcrum shaft 11, and can also be slid to either end of the guide rails 12, 12, so it can adapt to the topography of the field. In addition, the auxiliary seedling stand 8 can be positioned at an angle and position where it is most convenient to supply seedlings, which greatly increases work efficiency and reduces the labor and burden on the operator as much as possible.

After the seedlings have been supplied to the auxiliary seedling stand 8 as described above, the auxiliary seedling stand 8 is rotated back to its original position, and the locking pin 18 is inserted into the locking plate 19 and the pin hole 19a of the support frame 10. By inserting the auxiliary seedling stand 8 into the seedling stand 10b, the auxiliary seedling stand 8 is positioned and fixed in a proper mounting position parallel to the seedling stand 3 with one touch.

In the above embodiment, a riding-type rice transplanter has been described, but the present invention can be installed not only in a riding-type rice transplanter but also in a walking-type rice transplanter.

As described above, the present invention has an auxiliary seedling stand installed in the width direction of the rice transplanter, and is configured to be rotatable in the horizontal direction and slidable in the longitudinal direction. Since this device is equipped with a fixing device that locks the auxiliary seedling stand at the proper mounting position and angle with respect to the machine body by simultaneously preventing both the auxiliary seedling stand from rotating and sliding at the same time. Although the auxiliary seedling stand can be fixed in a well-balanced manner at the appropriate position of the machine with one touch, when feeding seedlings to the auxiliary seedling stand, it is difficult to feed seedlings to the auxiliary seedling stand by operating a single fixing device to the release side. The rotation lock and slide lock of the auxiliary seedling stand can be released at the same time, and the auxiliary seedling stand can be easily moved to the angle and position that is most convenient for the operator according to the topography of the field. Seedlings can be easily fed and placed directly on the auxiliary seedling stand from the road, etc., which greatly reduces the labor and burden on workers, and also reduces the time spent on seedling feeding work as much as possible. This has the effect of significantly increasing the efficiency of planting work.
