Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is directed to a pair of support shafts projecting laterally from both ends of a planting case that is driven to rotate around a horizontal axis of a machine body, and supports both the support shafts. Attach the planting claws to the shaft, and configure the seedling planting device so that both planting claws alternately cut out the seedlings from the seedling stand and plant them in the field as the planting case rotates. The present invention relates to a rice transplanter configured such that the provided agricultural powder and granular material feeding device and the seedling planting device are mechanically linked so that the agricultural powder and granular material feeding device is driven in association with the planting operation.

[Conventional technology]

In recent years, high-speed rice transplanters that perform one row of planting with two sets of planting claws have emerged as described above, and the existing type of rice planting plant that performs one row of planting with one set of planting claws has become popular. Compared with this, the planting speed can be almost doubled.

When such a high-speed rice transplanter is equipped with a fertilizer application that is one of the agricultural powder and granular material feeding devices, the planting claws of the seedling planting device and the fertilizer application are connected to a rod or the like in the same manner as existing models. It is considered that the fertilizer application device is configured to be mechanically interlocked and coupled through a linking mechanism to drive the fertilizer application by the planting operation of the planting claws.

As a connecting structure of the linking mechanism and the planting claw, a support shaft for mounting the linking mechanism is attached to a side surface of the planting claw, or a support shaft supporting the planting claw is attached from the side surface of the planting claw. It is configured so as to be extended and projected to substitute for the support shaft.

[Problems to be solved by the invention]

With the above-mentioned configuration, when switching to a rice transplanter not equipped with a fertilizer application, attachment and detachment of the support shaft is troublesome, and in a model in which the support shaft is projected, the end of the support shaft projects from the side surface of the planting claw. Will be planted in the state of
There is a risk that the protruding portion may come into contact with the planted seedlings and fall down the seedlings.

In view of the above-mentioned problem, the present invention has an object to obtain a connecting structure in which a support shaft or the like does not project from the side surface of the planting claw when the linking mechanism is removed.

[Means for solving problems]

According to a characteristic configuration of the present invention, a pair of support shafts are projected laterally from both ends of a planting case that is rotationally driven around a horizontal axis of the machine body, and the planting claws are attached to the both support shafts to attach the planting claws. The seedling planting device is configured so that both the planting claws alternately cut out the seedlings from the seedling stand and plant them in the field with the rotation of the attached case. In a rice transplanter configured to mechanically link the planting device and drive the agricultural grain and powder feeding device in conjunction with the planting operation, the support shaft end is exposed from the side surface of the planting claw. And a first linking member that bridges the agricultural powder and grain feeding device and the seedling planting device over the ends of the support shafts, and the first linking member and the agricultural powder and grain feeding device. By a linking mechanism including a second linking member that is installed over the power intake member of Ligated, and is to the mounting screw hole of the seedling planting apparatus of the linkage mechanism is provided on the support shaft end.

[Work]

In the type in which the support shaft is attached to the side surface of the planting claw or the support shaft of the planting claw is projected from the side surface of the planting claw, the linkage mechanism is attached to the projecting portion and tightened by a nut or the like. According to the configuration, the bolt and the like are screwed in together with the linkage mechanism from the outside. Therefore, the support shaft end portion of the planting claw can be set so as to slightly project from the side surface of the planting claw or be inward of the side surface of the planting claw.

〔The invention's effect〕

Therefore, the linking mechanism from the fertilizer applicator can be connected to the planting claw without using the support shaft dedicated to mounting the linking mechanism, and the structure can be simplified. Since the support shaft does not project, the projecting portion from the planting claw does not overturn the planted seedling unlike the conventional configuration.
