Description

[Detailed Description of the Invention] [Industrial application field] The present invention provides a spare seedling stand on the seedling placing table above the seedling placing surface. The present invention relates to a preliminary seedling replenishing device that is configured to be swingably switchable between a preliminary seedling replenishing posture in which the auxiliary seedling is replenished by tilting to the front and a supplementary preventing posture in which the preliminary seedling is prevented from being replenished by separating from the seedling mounting surface.

[Conventional technology]

As the above-mentioned preliminary seedling supply device, the present applicant previously applied for Japanese Patent Application No. 1-37067.

In this structure, a gate that rotates on the same surface as the seedling mounting surface is provided at the spare seedling outlet portion of the spare seedling stand in order to prevent the spare seedling from sliding out of the outlet.

[Problems to be solved by the device]

In the above-mentioned preliminary seedling supply device, when the preliminary seedling stand is switched to the preliminary seedling supply posture, the preliminary seedling is pushed by its own weight to push the gate to be supplied to the seedling placing surface of the seedling placing table. However, in this case, the preliminary seedlings try to slide out because there is nothing to prevent the movement when the gate is opened on the upper surface side of the bed soil part, but the friction resistance of the seedling mounting surface on the lower surface side of the floor soil part. The front part of the floor soil part is distorted and the front part of the floor soil part is rolled downwards by receiving the gate and the lower part of the front part of the floor soil part is slipped off by the gate, and the preliminary seedlings are worm-shaped. There was the inconvenience that it tended to bend.

Therefore, as a means for solving the above drawbacks, it is conceivable that the gate can be configured to swing open around an upper fulcrum to give sliding resistance to the upper surface side of the bed soil of seedlings. In addition, since the preliminary seedlings are held between the upper and lower sides by the seedling mounting surface and the gate, the sliding resistance becomes too large, which causes another inconvenience that smooth sliding of the preliminary seedlings is hindered.

The purpose of the present invention is to improve the structure of the gate so that the spare seedlings are unlikely to be in the scale of insects when the spare seedlings are supplied to the seedling mounting table, and that the spare seedlings can be supplied smoothly with less sliding resistance. And

[Means for solving the problem]

The feature of the present invention for achieving the above-mentioned object is to replenish the seedling mounting table with the end portion of the spare seedling outlet side tilted toward the seedling mounting surface side above the seedling mounting surface. A preliminary seedling stand that is swingably switchable between a preliminary seedling replenishing posture that allows the preliminary seedling replenishing posture and a replenishment preventing posture that separates the end on the outlet side of the preliminary seedling from the seedling mounting surface to prevent the replenishment of the preliminary seedling, In the spare seedling replenishing device, which is provided with a gate capable of swinging switching between a closed posture for preventing the spare seedling from sliding out and an open posture for allowing the spare seedling to slide out, the gate is , Configured to swing around the lower swing fulcrum and open and close in the vicinity of the swing fulcrum, and outside the seedling placement surface to guide the movement of the preliminary seedlings with the gate open. The seedling slide roller is installed, and its action and effect are as follows. A.

[Action]

By providing the seedling sliding roller at a position outside the spare seedling mounting surface of the spare seedling stand, when the gate is not opened and the supply is not performed, the seedling sliding roller is made inactive to the spare seedling, and the spare seedling is spared. When the gate is opened, it is possible to maintain a stable hold in the stand,
A seedling slide roller can be acted on the preliminary seedlings to be slid out, and the seedlings can be guided so as to promote the sliding out. Therefore, it is possible to suppress the distortion of the front surface of the floor soil portion due to the frictional resistance, and to suppress the occurrence of partial bending like a scale insect due to the front surface of the floor soil portion being wound downward.

Moreover, since the gate rotates around the lower fulcrum, it does not give a sliding resistance to the upper part of the floor soil.

[Effect of device]

As a result of the above configuration, when supplying the preliminary seedlings to the seedling mounting table, it is possible to avoid the preliminary seedlings from deforming like a scale insect, and moreover, the preliminary seedling table and the gate do not hold them from above and below, and the sliding resistance is small. Can smoothly supply seedlings.

Moreover, since the seedling sliding roller is a free-rolling roller that can roll under the seedling load, it does not require a special drive mechanism as compared with the case where it is forcibly driven through a drive device such as an electric motor, and the device is simple. Cost reduction.

As shown in FIG. 2, the seedling planting device (2) has a forward tilted seedling placing table (4) and a rotating case (5) that reciprocate left and right with a constant stroke with respect to the planting transmission case (3). Consisting of planting claws (6), (6), grounding floats (7), and fertilizer applicator (8) for cutting out and planting seedlings from the lower end of the placed seedlings while drawing an oval locus with the rotation of In the lower part of the seedling placing table (4), a pair of protruding belt type seedling vertical feeding mechanisms (9) for feeding the placed seedling downwardly each time the seedling placing table (4) reaches the stroke end are provided in pairs. .

Then, above the seedling mounting surface (4a) of the seedling mounting base (4),
A reserve that can be swung between a spare seedling replenishing position that tilts to the seedling mounting surface (4a) to supply the spare seedling and a supply blocking position that is separated from the seedling mounting surface (4a) to prevent the supply of the spare seedling. Seedling stand (10)
Is provided and is configured to release the locking of the locking mechanism (11) and switch to the preliminary seedling supply posture.

As shown in FIG. 6, the locking mechanism (11) includes a locking member (12) that is swingable around the horizontal axis (a) and is lightly urged in a clockwise direction in the figure. , Consisting of an electromagnetic solenoid (13) equipped with a core (13a) that can move in and out laterally,
When the electromagnetic solenoid (13) is energized and excited and the core (13a) retracts, the locking and fixing action on the locking member (12) is released, and the locking member (12) receives and locks. The existing seedling stand (10) swings downward due to its own weight,
It is configured to switch to the preliminary seedling supply posture. still,
The locking member (12) of the locking mechanism (11) is a spare seedling stand (10).
It acts on the receiving member (10a) provided at the center of the front end of the elastically retractable member.

Then, as shown in FIG. 2 and FIG. 5, the seedling placing table (4) is provided at the center of the seedling placing mechanism (9) in the lateral direction of the seedling placing mechanism (4) and at the center position in the vertical feeding direction. A seedling remaining amount sensor (14) is provided which is switchable between a non-detection state in which it projects upward from the seedling placement surface (4a) and a detection state in which it retreats below the seedling placement surface (4a) depending on the weight of the seedling. When the remaining seedlings on the seedling placing table (4) are running low and the seedling remaining amount sensor (14) is in a non-detecting state, the electromagnetic solenoid (13) is energized and differentially set to The lock mechanism (11) is linked to release the lock.
