DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling planting device for a rice planting machine, and more particularly, a support for rotatably supporting a pair of seedling planting claws is rotatably mounted on a machine body, and this support is provided. As the body is driven to rotate, a pair of seedling-planting claws are individually operated to rotate independently with respect to the support, and any of the seedling-planting claws is reciprocated up and down between the seedling rest and the field. By taking out the seedlings of one strain from the seedlings placed on the seedling rest, and carrying out seedling planting movement to descend and transport to the field, a pair of seedling planting claws alternate with the same planting strip as the aircraft travels The present invention relates to a seedling planting apparatus configured to plant seedlings in a plant.

[0002]

2. Description of the Related Art The above-described seedling planting apparatus has two plants per planting line.
By planting seedlings with one seedling planting claw and by planting the seedlings by revolving rotation and rotation, the planting work can be performed at high speed while suppressing the occurrence of drive vibration. However, conventionally, seedlings were supplied to the two seedling planting claws from the same seedling rest.

[0003]

Conventionally, the seedling mounting base is set so that the seedlings are picked up sequentially from one lateral end to the other end of the seedling placed on the seedling mounting base. It is necessary to reciprocate in the lateral direction of the machine in conjunction with the planting movement, and further compare the lateral feed speed of the seedling nest due to feeding from the same placed seedling to any seedling planting claw Since it is necessary to achieve a high speed, one heavy object consisting of a seedling rest and seedlings for supplying seedlings to two seedlings is moved relatively horizontally at a high speed, The weight balance between the left and right of the planting device was poor. Further, when the seedling rest reaches the end of the left and right lateral movement strokes, two vertical planting mechanisms are provided so as to forcibly transfer the placed seedlings to the seedling supply port side of the seedling rest. Since the consumption rate of the placed seedlings is relatively high in order to remove the seedlings from the placed seedlings, the number of times the vertical feed mechanism needs to be driven has been relatively large, and from this aspect, the suppression of the drive vibration has been insufficient. An object of the present invention is to provide a seedling planting apparatus capable of high-speed operation while maintaining a good weight balance and more sufficiently suppressing drive vibration.

[0004]

According to the present invention, there is provided a seedling planting apparatus for a rice transplanter according to the present invention, wherein a first seedling planting claw is rotatably supported around a first axis to achieve the object. And a claw support that rotatably supports the second seedling planting nail around a second axis parallel or substantially parallel to the first axis, parallel or substantially parallel to the first axis and the second axis. The first seedling rest and the second seedling rest for mounting and storing the seedlings to be planted are displaced in the longitudinal direction of the machine so that the first seedling rest and the second seedling rest are mounted so as to be rotatable and rotatable about a third parallel axis. The planting device is slidably attached to the body of the plant in the lateral direction of the machine, and with the rotation of the support,
The first seedling planting claw reciprocates up and down between the first seedling rest and the field to take out one plant seedling from the seedlings placed on the first seedling rest and is transported down to the field. The second seedling planting claw is reciprocated up and down between the second seedling rest and the field, so that one strain is placed from the seedling placed on the second seedling rest. The seedlings are taken out and the seedlings are moved downward to the field for planting. Further, the first seedling planting nails and the second seedling planting nails are alternately planted on the same planting line with the machine running. A claw operating mechanism for rotating the first seedling planting nail and the second seedling planting nail in rotation with respect to the nail support in an attached state, and interlocking with the seedling planting movement of the first seedling planting nail. The one seedling rest is reciprocated in the lateral direction of the machine, and the second seedling rest is interlocked with the seedling movement of the second seedling placement claw. Reciprocates in the lateral direction of the body, and further, the first seedling rest and the second seedling are placed in a state where the moving direction of the first seedling rest and the moving direction of the second seedling rest are opposite to each other. A seedling lateral feed mechanism that reciprocates the mounting table is provided.

[0005]

The seedling-planting claw performs seedling-planting movement by revolving rotation by the rotation of the nail support and rotation by the action of the claw operating mechanism. Even if the number of seedlings per unit time is the same as the number of seedlings per unit time in comparison with the planting device in which the seedlings are planted by the swinging rotation of the link mechanism by planting in the planting strips, the drive vibration Claw driving can be performed with less occurrence of the claw. The first seedling rest and the second seedling rest are reciprocated while moving in opposite directions to each other, so that the first seedling rest and a heavy object composed of the seedlings placed thereon and the second seedling rest are moved. And the heavy material consisting of the seedlings placed on it move in the opposite direction, and the heavy material for supplying the seedlings shifts only to one side of the left or right side of the machine, as in the conventional method. Seedlings can be supplied while avoiding lateral movement of the center of gravity of the mounting table and the placed seedlings as a whole. The first seedling rest and the second seedling rest are supplied separately to the first seedling planting nail and the second seedling planting nail, respectively, so that the consumption speed of the seedlings becomes slower than before, and the lateral feeding speed and the vertical feeding of the seedlings are reduced. The seedlings can be supplied where the seedlings are picked out at a desired size and at a picking pitch while the number of times of generation of the seedling moving inertia and the longitudinal feed drive vibration is reduced by reducing or reducing the number of times compared to the conventional method.

[0006]

According to the present invention, it is possible to efficiently work by high-speed planting in which a pair of seedlings are planted on the same planting strip, but not only the surface for planting claw drive but also the surface for seedling lateral feed speed and the seedling vertical feed drive. In addition, the occurrence of driving vibration is suppressed from the viewpoint of, and furthermore, the problem of weight balance caused by the lateral feeding of the seedlings is eliminated from both sides of the lateral feeding method and the lateral feeding speed, so that it is possible to work lightly and safely. It became something.
