Description

[Detailed description of the invention]

[0001]

The present invention relates to a spare seedling of a riding rice transplanter capable of effectively replenishing mat seedlings from each spare seedling rest at the rear of the machine to a spare seedling rest above the seedling rest at the planting section. It relates to a supply device.

[0002]

2. Description of the Related Art Conventionally, a large number of spare seedling stands are provided above the rear part of the machine, and the upper part of the seedling stand which is obliquely slidably reciprocable in a lateral direction at a planting portion at the rear of the machine. Above, in a riding rice transplanter equipped with a tilt-changeable spare seedling replenishing stand capable of replenishing mat seedlings on the seedling rest, the spare seedling rest cannot move laterally with respect to the seedling rest. It was erected like this.

[0003]

[Problem to be Solved by the Invention] However, when mat seedlings are replenished on the spare seedling replenishing stand from the spare seedling resting stand of the machine, the spare seedling replenishing stand which reciprocates in the horizontal direction together with the seedling resting stand is used. If they do not match the front side of the mounting table, it is difficult to replenish the mat seedlings from the spare seedling mounting table, damaging the mat seedlings, requiring a separate replenishing table, and planting In some cases, a mat seedling cannot be supplied on the spare seedling supply stand.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem and to effectively replenish mat seedlings on a spare seedling supply stand. The spare seedling replenishing stand is selectively slidable between the spare seedling rest and the seedling rest, while being mounted so as to be movable laterally with respect to the rest.

[0005]

Therefore, when the spare seedlings are mounted on the spare seedling replenishing stand and the mat seedlings can be replenished on the seedling rest, the spare seedling replenishing stand is aligned with the seedling rest and locked. In this case, the spare seedlings can be replenished in the same manner as before, and when the spare seedlings are replenished on the spare seedling replenishing stand, the spare If the seedling table is reciprocated in the horizontal direction, the mat seedlings can be effectively re-supplied while sliding on the spare seedling table even if the seedling table is reciprocating in the horizontal direction. it can.

FIG. 1 shows a side view of a riding rice transplanter. The machine A equipped with both front wheels 4, both rear wheels 5, a handle 6, a seat 7 and the like has a multi-stage spare seedling supply stand on both front sides. 1c, respectively, and a planting portion B which is connected to the rear of the machine A via a link mechanism 8 so as to be able to move up and down is provided above each planting case 10 which is constructed above each float 9. A plurality of seedling mounting surfaces are provided laterally on a seedling extraction plate 12 having a plurality of seedling extraction openings through which the claws 11 pass, and a vertical feed belt 13 and a seedling splicing sensor 14 are provided above the seedling extraction plate 12. The seedling table 2 which reciprocates in the horizontal direction and has a slanted structure is configured similarly to the conventional structure.

[0007] Brackets 15 projecting laterally are mounted on both sides of the upper end of the seedling mounting table 2, and a support shaft 16 is provided between the two brackets 15 so as to be horizontal.
Each support piece 17 vertically suspended from the upper part of the spare seedling replenishing stand 3 on which one mat seedling C can be placed, which is located above the upper part of the
Is slidably fitted to the support shaft 16 and is actuated by turning on the seedling splicing sensor 14 on a support plate 18 erected above the seedling mounting table 2 so as to face the lower end of the spare seedling supply table 3. The auxiliary seedling replenishing stand 3 is mounted above the suction rod 19a which is attached to and retracted from the solenoid 19.
The lower end surface of the support piece 17 is mounted so that it can move in the lateral direction, and an electromagnetic lock device 20 that can move the stopper 20a in the front-rear direction is fixed below the support piece 17, When the spare seedling replenishing stand 3 is aligned with the upper part of the seedling placing stand 2, the stopper 20 a projecting rearward engages with the engaging portion 21 erected on the bracket 15 to move the spare seedling resting stand 3 to the seedling placing stand 2. It is configured so that it can be locked above.

On the rear rear cover 22 of the machine A, support frames 23 are provided on both sides, respectively, and at the top and bottom between the two support frames 23, a spare seedling mounting table 1a on which mat seedlings C can be placed, respectively. , 1b, but the lower seedling rest 1b is fixed horizontally, and the upper seedling rest 1a at the upper end is fixed.
Is pivotally supported on a support shaft 24 laid on the front, and
The suction rod 25a of the solenoid 25 is freely retractable and retractable on the lower surface of the rear end of the a. When the suction rod 25a rides on the suction rod 25a, the suction rod 25a becomes horizontal, and the suction rod 25a is turned around the support shaft 24 and tilted by being retracted. When the auxiliary seedling supply 3 is aligned with the front side of the auxiliary seedling mounting table 1b, the stopper 20a projecting forward engages with the engaging portion 26 provided below the auxiliary seedling mounting table 1b. Thus, the spare seedling replenishing stand 3 can be locked on the spare seedling placing stand 1b side.

Therefore, when the mat seedling C is mounted on the spare seedling replenishing stand 3 as shown in FIG. 2 so that it can be replenished on the seedling placing stand 2, as shown in FIG.
When a is engaged with the engaging portion 21 so that the spare seedling replenishing stand 3 is aligned with the seedling placing stand 2 and locked, the spare seedling can be replenished as in the conventional case as shown in FIG. In order to replenish the spare seedlings on the spare seedling supply table 3, the spare seedling supply table 3 is moved in the lateral direction with respect to the seedling mounting table 2 so as to coincide with the front side of the spare seedling supply table 1 b, as shown in FIG. When the stopper 20a is engaged with the engaging portion 26 and locked as shown in FIG.
In the state shown in FIG. 5, the mat seedling C can be effectively replenished while sliding the mat seedling C from the spare seedling mounting table 1b. From the upper spare seedling mounting table 1a, as shown in FIG. Can be effectively replenished while the mat seedling C is slid by inclining.

[0010]

[Effects of the Invention] As described above, according to the present invention, when the spare seedlings are mounted on the spare seedling supply table 3 and the mat seedlings C can be supplied on the seedling mounting table 2, the spare seedling supply table 3 If the seedling table 2 is locked in alignment with the seedling table 2, supplementary seedlings can be replenished in the same manner as in the prior art. Is moved in the horizontal direction with respect to the seedling mounting table 2 and is aligned with the front side of the spare seedling mounting table 1b and locked on the spare seedling mounting table 1b side, so that the seedling mounting table 2 reciprocates in the horizontal direction. Therefore, the mat seedling C can be effectively replenished while sliding the mat seedlings C from the spare seedling mounting tables 1a and 1b. It has the feature that seedlings C can be replenished and can be suitably implemented.
