The seedling plant 21 is moved up and down via the lift link 18 by the expansion and contraction of the lift cylinder 19. Then, the posture is switched between the working posture and the non-working posture, and is adjusted up and down according to the depth of the soil surface. At this time, the seedling tank 3 is moved up and down while maintaining the substantially parallel form by the parallel link form of the lift link 18. Therefore, the seedling A loading state or seedling supply of each seedling tank 3 can be stabilized.

Here, the invention described in claim 1 is
A mat-shaped seedling A is placed on the seedling separation port 1 at the rear lower side while reciprocating left and right while being reciprocated, and the planting claws 2 act on the seedling separation port 1 to separate and plant the seedling A. In the seedling planting machine having the seedling tanks 3 to be performed, the auxiliary seedlings A are stored and supported at the upper end of each seedling tank 3 in the front-back horizontal state B,
The auxiliary seedling supply device is characterized in that the auxiliary seedling stand 4 for supporting the seedling tank 3 by supplying the stored seedling A to the seedling tank 3 while rotating in the inclined state C along the seedling tank 3 is supported.

Thus, the auxiliary seedling stand 4 is supported on the upper end of the seedling tank 3 and can accommodate and support the auxiliary seedling A in the front-rear horizontal state B. Can be moved up and down while maintaining a substantially horizontal state integrally with the seedling tank 3, so that the auxiliary seedling A can be supported in a stable state. By rotating the auxiliary seedling stand 4 to the inclined state C to follow the inclination of the seedling tank 3, the auxiliary seedling A on the auxiliary seedling stand 4 can be slid onto the upper surface of the seedling tank 3 and supplied. The seedling supply operation can be performed accurately and smoothly. Further, in such a supporting configuration of the auxiliary seedling stand 4, the seedlings can be replenished by using the space between the auxiliary seedling stand 4 and the upper part of the seedling tank 3, so that the seedling tank 3 is effectively used. And the restriction on seedling accommodation can be reduced. The auxiliary seedlings A can be accurately supplied to the seedling tank 3 with such a simple configuration.

The invention according to claim 2 is characterized in that the auxiliary seedling mounting table 4 is rotatably supported in a seesaw-like manner around a support shaft 5 at the upper end of each seedling tank 3. It is. As a result, the auxiliary seedling stand 4 is rotatably supported in a seesaw state before and after the support shaft 5 on the seedling tank 3. Therefore, in the horizontal state B, the front end projects forward from the upper end of the seedling tank 3. In this state, auxiliary seedlings can be easily mounted from the front vehicle body driver's seat side. In supporting and supporting the auxiliary seedlings A, the weight of the auxiliary seedlings 4 is distributed around the support shaft 5 so that the support of the auxiliary seedling stand 4 is balanced. When the auxiliary seedlings A are supplied to the seedling tanks, the entire mat-shaped seedlings A can be slid along the inclined surfaces of the seedling tanks 3 and the auxiliary seedling stands 4 by a seesaw-like inclination to smoothly supply them.

According to a third aspect of the present invention, the auxiliary seedling stand 4
Are characterized in that they are interlocked with each other so that they can be switched and rotated by a seedling sensor 6 for detecting a decrease in seedlings in each seedling tank 3. Thereby, the seedlings A of the auxiliary seedling stand 4 are detected by the seedling sensor 6 on the seedling tank 3 detecting the decrease of the seedlings.
Since it is supplied to the seedling tank 3, accurate automatic supply can be performed.

Further, the invention according to claim 4 is characterized in that the auxiliary seedling stand 4 is mounted and supported on an upper end of a tank support frame 7 for supporting the seedling tank 3 so as to be reciprocally movable left and right. is there. Thus, since the auxiliary seedling stand 4 is mounted and held on the tank support frame 7 for guiding the reciprocating movement of the seedling tank 3 from side to side, the center of gravity is shifted without moving the seedling tank 3 in the left and right direction. And accurate seedling planting can be maintained as a stable support form.

Here, the auxiliary seedling stand 4 is provided with each seedling tank 3
Each is independently rotatably provided in a seesaw shape about the support shaft 5. The front portion has a box-shaped configuration, and the rear portion has a long fork-shaped configuration, and is set at the front center of gravity as the entire auxiliary seedling stand 4. A stopper 31 that is bent upward is formed at the rear end of the fork. When the auxiliary seedling A is placed on the auxiliary seedling stand 4, the auxiliary seedling A is in the state of the rear center of gravity. Auxiliary nursery stand 4
The support shaft 5 integral with the supporting shaft 5 is rotatably supported by the tank support frame 7. Each support shaft 5 has a claw ring 32. The claw ring 32 has a seedling sensor 6 of the seedling tank 3 and a rod 33.
By engaging the interlocking locking claw 34, the rotation of the auxiliary seedling stand 4 to the inclined state C can be locked to maintain the front and rear horizontal state, and by releasing this engagement, By rotating the auxiliary seedling stand 4 at the rear center of gravity to the rear lower inclined state C, the upper seedling tank 3 can be approached or polymerized. Reference numeral 36 denotes a spring that resiliently moves in a direction in which the locking claw 34 is released.

The auxiliary seedling stand 4 is provided with the auxiliary seedling A as described above.
In the empty state where no seedlings are placed, the center of gravity is on the front side, and is in the front-rear horizontal state B around the support shaft 5; 3
Can be turned to the inclined state C along the axis, but instead of this, it is also possible to configure to mechanically and electromagnetically switch and rotate.

At the upper end of the seedling tank 3, there is formed a groove 35 into which the fork-shaped stopper 31 can be fitted, and when the stopper 31 sinks into this groove 35, the seedling on the upper surface of the auxiliary seedling stand 4 is formed. A is slid to the seedling tank 3 side and supplied. The rotation of the auxiliary seedling stand 4 is such that the seedling tank 3
The seedling sensor 6 provided in the center of the process detects the decrease in seedlings. The seedling sensor 6 is disposed below the groove 35 and protrudes from the upper surface of the seedling tank 3 when there is no seedling A. When the seedling A is supplied to the upper surface of the seedling tank 3, the weight of the seedling A is increased. And is moved down around the sensor shaft 37. Then, the locking claw 34 is rotated around the claw shaft 38 against the spring 36 via the rod 33, and
To the claw ring 32 side. At this time, since the auxiliary seedling stand 4 is in the inclined state C, the locking claw 34 does not directly engage with the claw ring 32, but when the seedling A supplied to the seedling tank 3 is moved down over the stopper 31, Even if the seedlings A remain on the seedling sensor 6, the empty auxiliary seedling stand 4 is returned to the horizontal state B from the inclined state C by the front center of gravity. By this rotation, the claw wheel 3
2 also rotates and engages with the locking claw 34, so that even if a new auxiliary seedling A is placed on the auxiliary seedling stand 4 in the horizontal state B and the center of gravity is set to the rear center of gravity, the auxiliary seedling A is rotated to the inclined state C. Not done.

Instead of such a mechanically linked seedling sensor 6, a control structure in which the auxiliary seedling stand 4 is electromagnetically rotated may be in the form of a limit switch or a photoelectric sensor. The seedling A taken out from the seedling mounting shelf 17 is placed on the auxiliary seedling stand 4 in the horizontal state B, and is ready for seedling supply. When the number of seedlings in the seedling tank 3 decreases due to the seedling planting operation, the auxiliary seedling stand 4 is rotated from the horizontal state B to the inclined state C by the detection of the decrease in the seedlings by the seedling sensor 6, and this seedling A becomes the auxiliary seedling. Stand 4
Is supplied to the seedling tank 3 by sliding. After the supply of the seedling A, the auxiliary seedling stand 4 returns to the horizontal state B, and the next auxiliary seedling A
Can be placed. The supply of the auxiliary seedlings A to the seedling tanks 3 is performed in a state where each of the seedling tanks 3 that reciprocate left and right is aligned with a position facing each of the auxiliary seedling stands 4.

The seedling plant 21 is moved up and down between the seedling planting position and the non-seedling planting position, or switches the lift control valve of the hydraulic circuit of the lift cylinder 19 by the vertical movement of the center float 25 depending on the soil depth. In many cases, lifting and lowering control such as automatic raising and lowering is performed. However, since the front and rear horizontal state B is maintained by the lift link 18, the seedlings A are easily placed on the auxiliary seedling stand 4. Seedling A movement is reduced and stable seedling A support is performed. Also, in supplying seedlings to the seedling tank 3, since the auxiliary seedling stand 4 follows the inclination angle of the seedling tank 3, excessive compression and distortion of the seedlings A are reduced, and accurate seedling supply action is achieved. Let it do.

Since such an auxiliary seedling stand 4 is supported in a seesaw shape across the support shaft 5 at the upper end of the seedling tank 3, the auxiliary seedling stand 4 is protruded long to the front driver's seat 9 side, and It is easy to supply seedlings from the loading shelf 17 side. Further, when the auxiliary seedling stand 4 is in the inclined state C, the auxiliary seedling stand 4 can be extended upward along the inclined surface of the seedling tank 3, so that a sufficient space for replenishing seedlings can be maintained. Thus, it is easy to perform the sliding supply by the inclination. Furthermore, the weight balance between the front and rear of the seedling plant 21 or the whole seedling machine can be improved, and the front and rear length can be reduced.

In the form in which the auxiliary seedling 4 is supported on the tank support frame 7 at a fixed position with respect to the seedling frame 22, the auxiliary seedling 4 does not move left and right. Small and stable seedlings can be planted. The fork portion at the rear part of the auxiliary seedling stand 4 is drawn out from the front part, or as a folded form,
When the fork is in the way, the fork can be pushed forward or folded up. Thus, when the seedlings are directly supplied to the seedling tank 3 before work or the like, the fork portions do not interfere with the supply of the seedlings, and the seedlings can be easily supplied.
Thereafter, when placing the seedlings 4 on the auxiliary seedling stand 4, the fork portion may be pulled out or deployed rearward.
