Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter that is equipped with a seedling planting device having a seedling weighing stand that is reciprocally movable in left and right directions and a spare seedling mounting stand.

Normally, rice transplanters are equipped with a spare seedling stand as a means of increasing the amount of seedlings that can be loaded onto the machine at one time and improving work efficiency.

When providing a spare seedling stand that is advantageous in terms of work efficiency, for example, if this spare seedling stand is integrally connected to the reciprocating seedling weighing stand of the seedling planting device, The feeding of seedlings from the loading table to the seedling weighing table is automated, which is more convenient for work.

However, this preliminary seedling loading platform, which has a considerable weight due to the amount of preliminary seedlings loaded, must also be moved back and forth in the left and right directions at the same time, which not only increases the power required for reciprocating the seedling loading platform. Since the heavy objects move back and forth in the lateral direction, the center of gravity of the aircraft is unstable and the lateral balance of the aircraft is easily lost.

This causes a significant deterioration in maneuverability, especially in the case of a walking rice transplanter.

In view of the above points, the present invention aims to stabilize the center of gravity of the machine by fixedly providing a spare seedling platform on both left and right sides of the center part in the left-right direction of the machine. While maintaining good maneuverability, it is possible to load a large amount of seedlings at a time, and for planting from this spare seedling platform, it is possible to easily and quickly supply seedlings to the seedling weighing platform of the device. It is intended to be fake.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIGS. 1 and 2 show a vehicle installed between the front and rear wheels 5 and 6 at the lower part of the widthwise central portion 1 of the body A, via a parallel link mechanism 7 and a chain body 8, in a state that it can be raised and lowered relative to the body A. A mid-mount type riding rice transplanter is shown in which a seedling planting device 4 is arranged in a connected and supported manner. Land leveling float 9・
・And a seedling weighing table 3 which is curved and inclined from the rear lower part to the front upper part in the direction of travel and is movable back and forth in the left and right lateral directions.
The seedlings taken out from the seedling take-out port 3a of the seedling weighing table 3 are planted in units, and the seedlings taken out from the land leveling float 9 are planted in the notch 9.
The planting to be planted on the mud surface through a... is made up of a claw 10... and a drive section 11 that controls the drive of the claw 10. Preliminary seedling mounting tables 2, 2' are provided, and the seedling mounting table 3 of the device 4 for planting the seedlings is placed on the lower side in the direction in which the preliminary placed seedlings are sent out from the preliminary seedling loading tables 2, 2'. are doing.

As clearly shown in FIG. 3, the preliminary seedling mounting tables 2, 2' are
Due to the elastic force of the springs 12, 12', etc., the horizontal position is biased in the direction of contacting the stoppers 13, 13', and the movement around the pivot part 16 is linked to the operation of the stepping lever 15 provided on the control part 14. By swinging the seedling mounting table 3 to a seedling supplying position for supplying pre-placed seedlings to the seedling mounting table 3, the seedling mounting table 3 can be switched to a seedling feeding position in which pre-placed seedlings are supplied to the seedling mounting table 3. It is configured to move back and forth between the outer sides 2a and 2a' of the .

Incidentally, when supplying the preliminary seedlings loaded on the preliminary seedling mounting tables 2 and 2' to the seedling loading table 3, the seedling loading table 3 is stopped at the end of the forward movement or the end of the backward movement. In this state, the stand is raised to a predetermined height, and the preliminary seedling mounting tables 2, 2' are switched from the horizontal position to the seedling supplying position.

FIG. 4 shows another embodiment, which is a rear cloak type riding rice transplanter in which a seedling planting device 4 is supported and connected to the rear of the machine so that it can be raised and lowered via a parallel link mechanism 7. Spare seedling stands 2, 2' are provided on both left and right sides of the widthwise central portion 1 at the rear of the aircraft, and the seedling planting table 3 of the device 4 is used for seedling planting. The seedling mounting table 3 of the device 4 is placed on the lower side in the sending direction of the preliminary seedlings from 2', and the seedling mounting table 3 of the device 4 is used for seedling planting.
.

In summary, the present invention provides the following advantages:
Spare seedling mounting tables 2, 2' are provided on both left and right sides of the table, and the seedling trays 2, 2' are movable back and forth in the left and right directions to the lower position in the direction of sending out the seedlings placed in advance and prepared from these preliminary seedling loading tables 2, 2'. The seedling planting machine having a seedling mounting table 3 is a rice transplanting machine in which a device 4 is arranged, and each outer side 2a, 2 of the preliminary seedling mounting table 2, 2' is used for seedling planting.
It is characterized in that a' is disposed so as to correspond to the end of the movement range of the seedling table 3 on the outer side of the body.

In other words, by fixedly providing the spare seedling loading platform on both sides of the center portion in the lateral direction of the machine, it is possible to stabilize the center of gravity of the machine, which improves the maneuverability, especially in the case of a walk-behind rice transplanter. At the same time, it is possible to increase the amount of seedlings loaded each time and improve the efficiency of seedling planting.

Moreover, by providing the preliminary seedling mounting tables 2, 2' fixedly on both the left and right sides of the center portion in the left-right direction of the machine, the seedlings of the preliminary seedlings mounted on the preliminary seedling loading tables 2, 2' can be easily removed. In view of the fact that it becomes difficult to supply the seedling table 3, the outer sides 2a, 23' of the spare seedling table 2, 2' are positioned corresponding to the outer end of the machine body of the movement range of the seedling table 3. By arranging the stand 2゜2' and the movable seedling weighing stand 3,
This makes positioning easier and allows seedlings to be supplied from the standby seedling stands 2, 2' to the seedling stand 3 easily and quickly.
