There was one configured to take out the stock.

[0003]

According to the above-mentioned conventional configuration, since each claw plate is lifted and lowered while keeping the thrust position to take out the stock, for example, the stock to be taken out is a good plant for supplemental planting, and When the leaves have grown greatly and protruded outside the peripheral wall of the pot for growing seedlings, the nail plate descending from the nail support member damages or cuts the leaves to hinder the growth. If the target strain is a defective strain that has grown to a size of the above-mentioned good plant for supplementary planting, the nail plate similarly cuts leaves, and the cut leaves are scattered around the seedling-growing pot, There was a problem that cleaning work was required.

The present invention has been made in view of the above points, and an object thereof is to damage a leaf of a plant when the nail plate descends from the nail support member and plunges into the pot for growing seedlings. It is possible to prevent cutting, and the poor growth of the good plant caused by scratching the good plant leaf with the nail plate, and the surrounding of the pot for growing seedlings caused by cutting the bad plant leaf with the nail plate The purpose is to eliminate the need for cleaning work.

[0005]

[Means for Solving the Problems]

[Structure] The characteristic structure of the invention according to claim 1 is, in the plant take-out device from the seedling-growing pot described at the beginning,
While the distance between the tip portions of each claw plate is configured to be adjustable and adjustable, each claw plate is inserted into the inner wall of the seedling-growing pot in the up-down direction, and the tip portions of the claw plates from this inserted position. A switching means is provided on the back side of the claw plate for switching to an open position, and each claw plate descends in the open position so that the tip surface of the claw plate reaches near the upper surface of the seedling-growing pot, and the seedling in the rushing position. A control device for controlling the switching means so as to plunge and descend into the growing pot is provided.

According to a second aspect of the present invention, the leaf of the plant in the seedling-growing pot is provided from the time when the nail plate starts descending from the nail-supporting member until the time when the nail plate plunges into the seedling-growing pot. There is a suction nozzle disposed between the plurality of claw plates for sucking the air around the above and causing the leaves of the plant to move vertically.

According to a third aspect of the present invention, the interval between the plurality of claw plates is set so that the claw plates can project into a position spaced inward from the peripheral wall of the seedling-growing pot inward of the pot. Then, the plant posture detecting means for detecting the posture of the cotyledon of the plant in the seedling-growing pot in a plan view is provided, and the plurality of claw plates are provided with a rotatable mechanism rotatable about the central axes of those claw plates, Based on the detection result of the stock posture detecting means, the rotating mechanism is controlled so that the descending posture of the nail plate in plan view from the nail supporting member corresponds to the posture of the cotyledon of the plant. A control device is provided.

[Operation] According to the construction of claim 1, [a] each nail plate descends from the nail support member to the seedling-growing pot side in a state of being set in an open posture in which the tip end portion is open to the nail plate back side. When the tip surface reaches near the upper surface of the seedling-growing pot, the control unit switches and controls the switching means to set each claw plate in a rushing posture along the inner wall of the seedling-growing pot in the vertical direction. Then, it is possible to plunge and descend into the pot for growing seedlings.

Since each claw plate is operated as in the above [a], the claw plate descends from the claw support member even if the leaves of the [b] strain are protruding to the outside of the peripheral wall of the seedling-growing pot. Then, when plunging into the pot for growing seedlings, it becomes difficult to contact the leaves of the plant, and it is possible to prevent the leaves of the plant from being damaged or cut.

[0010] According to the structure of claim 2, [C] during the period from the time when the nail plate begins to descend from the nail support member until the time when the nail plate plunges into the seedling-growing pot, the suction nozzle is used to Since the air around the leaves is sucked upward and the leaves of the strain are arranged along the vertical direction, the same operation as the above [b] can be achieved.

According to the structure of claim 3, [d] by setting the facing distance between the plurality of nail plates as described above, the nail plates are separated from the peripheral wall of the seedling-growing pot inward of the pot. Since it plunges into the position where the seedlings are grown, it is possible to leave the medium near the peripheral wall of the seedling-growing pot and hold only the medium around the bad and good plants with the nail plate to take out. Even if the medium is not fully spread in the pot and the medium on the inner peripheral wall side of the seedling growing pot is not yet united and easily collapses, the medium should be removed when removing the medium from the seedling growing pot. It can be held stably.

[E] By providing the stock posture detecting means, the rotation mechanism, and the control device as described above, for example, the claw plate before the plunge into the seedling-growing pot can move in the longitudinal direction in plan view. Even if the cotyledons are located from both sides, before the plunge into the seedling-growing pot of the nail plate, the plant posture detection means detects the posture of the cotyledon of the plant in the seedling-growing pot in plan view. Then, based on this detection result, the control device controls the rotation mechanism so that the descending posture of the nail plate in the plan view from the nail support member corresponds to the posture of the cotyledon of the plant, and the cotyledon of the cotyledon in the plan view It is possible to set the posture so that it is sandwiched from both sides in the width direction, and it becomes difficult for the claw plate that descends into the pot for seedling growth to contact the cotyledons of the plant, and the cotyledons of the plant are not damaged or cut. It can be prevented.

[Effect] Therefore, according to the constitution of claim 1, due to the above-mentioned actions [a] and [b], the poor growth of the good plant due to the damage of the leaves of the good plant by the nail plate, and the nail plate Therefore, it was possible to eliminate the work of cleaning the leaves around the seedling-growing pot, which was caused by cutting the leaves of the defective plants.

According to the structure of claim 2, the above-mentioned action [C]
As a result, it is possible to achieve the same effect as the effect according to claim 1.

According to the third aspect of the present invention, the above operations [d] and [e] allow the work to be performed smoothly even when the medium in the seedling-growing pot is not organized and easily collapses. Even if possible, even if the plurality of nail plates before plunging into the seedling-growing pot are positioned so as to sandwich the cotyledon from both sides in the longitudinal direction of the cotyledon in a plan view, or the cotyledon of the plant is a seedling-growing pot. Even if it is biased to the peripheral wall side, the growth of good plants caused by scratching the cotyledons of good plants with the nail plate, or seedling growth caused by cutting the cotyledons of bad plants with the nail plate Cleaning the leaves around the pot has become unnecessary.

Is a cylinder (not shown) in a defective plant removing device body 6a (an example of a nail support member) having a bracket 14 to which two vertically long claw plates 10 for holding defective plants in the seedling growing pot 4 are attached. (1) is supported by the defective plant removing device main body 6a so as to be movable up and down, and each nail plate 10 is brought close to the seedling-growing pot 4, and each nail plate 10 is brought into contact with the seedling-growing pot 4.
It is configured such that it can be freely switched to the claw separated state separated from.

Each claw plate 10 is supported by a bracket 14 so as to be vertically movable via two pencil-type first cylinders S1. When the claw plate 10 is in the proximity of the claws, the first cylinder S1 is extended to drive each claw plate. The plate 10 is configured to be able to plunge into the seedling growing pot 4. Specifically, the two first cylinders S

(4) The first cylinder S1 is driven to extend, and the claw plate 10 plunges into the seedling-growing pot 4 at a position spaced inward from the inner peripheral wall of the pot (see FIG. 24). As described above, the descending posture of the nail plate 10 in plan view is set to correspond to the posture of the cotyledon of the plant, and the nail plate 10 is set to sandwich the cotyledon from both ends in the width direction in plan view. Therefore, it is possible to make it difficult for the claw plate 10 that descends into the pot 4 for growing seedlings to interfere with the cotyledons of the plant. (5) The cylinder in the supplementary planting apparatus main body 7a is shortened to raise the support bracket 14, and the good plant is held by the nail plate 10 and taken out from the seedling growing pot 4 (see FIG. 25). Since the pressing ring 12b presses the upper end of the seedling-growing pot 4, it is possible to prevent the seedling-growing pot 4 from being lifted up when the good plant is taken out. In addition, as described above, the claw plate 10 plunges into the seedling-growing pot 4 at a position spaced inward from the inner peripheral wall of the pot 4, thereby explaining the operation of the defective plant removing device 6. The same effect can be achieved.
