Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling transplanting device that divides one seedling from a seedling outlet of a seedling stand and plants the divided seedlings at a planting position.

A seedling transplanting device for fields that uses pine-shaped seedlings divides one seedling from the seedling take-out port of the seedling stand with a planting claw, holds it in the planting claw, and places it in the field soil at the planting position. The seedlings are transplanted by inserting their roots into the seedlings, but depending on the type of crop being transplanted, the roots of the pine-like seedlings may be weakly intertwined, and in the case of such pine-like seedlings, When dividing a single seedling with the planting claw, the seedbed collapses and the seedlings tend to fall off, and in the case of soybean seedlings where the leaves are heavier than the roots, it is difficult to hold them in the planting claw. Seedlings tend to turn upside down, and both of these can cause plant failure.

In view of the above-mentioned actual situation, the present invention provides a seedling planting mechanism equipped with a planting claw that divides and holds one seedling from the seedling take-out port of the seedling stand and plants the seedling at the planting position. The planting mechanism is provided with a groove fork consisting of a vertical piece substantially parallel to the planting claw and a horizontal piece perpendicular to the planting claw in correspondence with the planting claw, and when the seedlings are divided by the planting claw. And, while the seedlings for one divided and held plant reach the planting position, the seedlings are supported from below by the horizontal piece of the trenching fork, and at the planting position, the trenching fork is used in advance of planting the seedlings. The apical corner of the holder is configured to create a planting groove, making it easy to divide a single seedling from the seedling take-out port of the seedling stand using the planting claws, and when planting by holding the seedlings between the seedlings. While being transferred to the new location, the horizontal piece of the ditching fork securely supports the seedbed of each seedling, which is divided and held by the planting claws, from below to prevent the seedling from falling off and hold it. However, it is not possible to wipe out the occurrence of missing plants, but the apical part of the trenching fork is used to create the planting trench prior to planting the seedlings, and a special trenching mechanism is required. It is an object of the present invention to provide a seedling transplanting device that can simplify the mechanism.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. 1 is a seedling platform; 2 is a seedling planting mechanism; Face plates 4 are disposed opposite each other, and the seedling stand 1 is linked to a mechanism that reciprocates left and right at a pitch the width of one seedling. The seedling planting mechanism 2 includes a planting arm 6 having a pair of planting claws 5, 5 at its tip, and a reciprocating mechanism 7 for driving the planting arm 6 up and down. A crank arm 9 connected to a shaft 8 is pivotally connected to a crankshaft 10, and the base end of the planting arm 6 is pivotally connected to a crankshaft 12 of a bell crank 11. 6 is reciprocated up and down so that a pair of planting claws 5, 5 at the tips thereof trace a loop-shaped trajectory (dotted line trajectory in Fig. 2) between the seedling extraction port 3 in the upper part and the planting position in the lower part. It is becoming more and more like this. 13 is a pivot shaft of the bell crank 11. Further, 14 is a groove-making fork, and the groove-making fork 14 is a vertical piece that is substantially parallel to the planting claws 5, 5 so that its tip acting portion corresponds to the lower end of the pair of planting claws 5, 5. 14a and the horizontal piece 14b orthogonal to the planting nails 5,5,
It is formed in an L-shape having an apex corner 14c.
The groove fork 14 is connected to the vertical reciprocation of the planting arm 6 when the planting claws 5, 5 separate a single seedling from the seedling outlet 3, and when the planting fork 14 is held in the lower part. While reaching the planting position, the horizontal piece 14b supports the seedbed from below in correspondence with the lower ends of the planting claws 5, 5, and when the planting position is reached, the planting groove fork 14 supports the planting claws 5, 5. It operates so as to draw a loop-shaped trajectory (the chain line trajectory in FIG. 2) that goes forward and cuts a planting groove at the apex portion 14c, and then returns upward. Therefore, the groove forming fork 14 is pivotally attached to the crankshaft 10 via the fork arm 16,
Further, the fork arm 16 is connected to a bell crank 17 via its crankshaft 18, and the bell crank 17 is pivotally mounted to a pivot shaft 19. 2
0 is a seedling extrusion fork, and the seedling extrusion fork 20 is interposed between the planting claws 5 and 5, and is interlocked with the planting arm 6 to push the seedling extrusion fork between the planting claws 5 and 5 at the seedling planting position. It functions to push the clamped seedling downward. A is a pine-shaped seedling, and b is the field soil surface at the planting position.

In the structure as described above, seedling stand 1
The upper pine-shaped seedling a is divided into single seedlings by the planting claws 5, 5 from the seedling outlet 3, and the divided seedlings are held by the planting claws 5, 5 and sent downward. transported to the planting position. And the above-mentioned planted nail 5,
In the process of dividing a single seedling and moving it to the planting position according to step 5, the horizontal piece 14b forming the tip acting part of the cropping fork 14 supports the seedbed of the seedling from below and doubles as a seedbed support. Therefore, the seedbed does not collapse when dividing one seedling by the planting claws 5, 5, and the division of the seedlings is carried out smoothly and reliably. To reliably prevent one seedling from falling off when it is transferred to a new location. On the other hand, as described above, when the planting claws 5, 5 reach the planting position while holding one seedling, the groove fork 14 precedes the planting claws 5, 5, and the apical corner part 14
At c, a planting groove is formed in the field soil at the planting position, and the groove fork 14 is then raised. Then, after trenching is done by the trenching fork 14, one seedling is pushed downward by the seedling extrusion fork 20 and planted.

As described above, when dividing one seedling by the planting claws 5, 5, and in the process of holding the seedling by the planting claws 5, 5 and transferring it to the planting position, the planting groove fork 14 Since the seedbed is securely supported from below by the support, even if the roots of the pine-shaped seedlings are weakly intertwined, the seedbed can be divided without destroying the bed. Even if the seedlings are transferred, it is possible to prevent the seedlings from turning over and falling off during transportation. Furthermore, at the planting position, the grooves are cut prior to planting the seedlings by the advance operation of the groove-cutting fork 14, so there is no need to provide a groove-cutting mechanism.

In short, the present invention provides a seedling planting mechanism equipped with a planting claw that divides and holds one seedling from a seedling take-out port of a seedling stand and plants it at a planting position. A groove fork consisting of a vertical piece approximately parallel to the planting nail and a parallel piece perpendicular to the planting nail is provided corresponding to the planting nail, and the planting nail is used to divide and hold the seedlings. While each seedling reaches the planting position, the seedling is supported from below by the horizontal piece of the fork, and at the planting position, the vertical angle of the fork is adjusted prior to planting the seedling. Since the section is configured to create a planting groove, it is possible to divide one seedling from the seedling take-out port of the seedling stand using the planting claw, and also to hold the divided seedlings and transfer them to the planting position. During the interval, the bed of one seedling, which is divided and held by the planting claw, is firmly supported from below by the horizontal piece of the ditching fork to prevent the seedling from falling off, and to prevent the seedling from falling off. In addition to being able to eliminate the occurrence of grooving, the apex of the grooving fork allows furrowing to be done prior to planting seedlings, eliminating the need for a special grooving mechanism and simplifying the mechanism. It has very useful novel effects, such as the ability to
