Description

Detailed Description of the Invention

[0001]

The present invention relates to a seedling planting mechanism, a seedling stand,
The present invention relates to a rice transplanter equipped with a seedling planting device equipped with a ground float on a traveling machine body.

[0002]

2. Description of the Related Art For example, in a multi-row rice transplanter such as a six-row or eight-row planting, the lateral width of the seedling planting device is too wide and the lateral width of the building is too wide in the working state. In some cases, they may come into contact with each other and may not be able to drive on the road.In addition, when the rice transplanter is mounted on a carrier vehicle and transported, it may protrude beyond the width of the truck bed. I was having a hard time. Therefore, in the past, for example, when driving on the road, for example
As shown in Japanese Patent Laid-Open No. 36-36, the seedling planting device was detached from the elevating link, and the seedling planting device was laid sideways, and was again locked to the elevating link to run on the road.

[0003]

With such a configuration, it is necessary to perform work such as removing and reattaching the seedling planting device, which increases the burden on the operator and the seedling planting. Since the form of the attachment device is the same as that of the attachment device, there is still no solution to the problem that the attachment device may protrude from the loading platform when it is mounted on the carrier. An object of the present invention is to introduce a folding structure into a working device provided with a fertilizer application device and a seedling planting device, which can be transformed into a compact shape as compared with the time of working, and at the time of work such as maintenance of the seedling planting device. In the above, there is a point of providing a rice transplanter capable of changing the settings of the fertilizer application and the like in consideration of workability and reducing the work burden on the operator for changing the settings.

[0004]

The features of the present invention are a seedling planting mechanism equipped with a seedling planting mechanism, a seedling stand, and a grounding float, and a granular material for managing the seedlings planted on the field surface. Or, a working device including an auxiliary device for supplying fertilizer is attached to the traveling machine body so that the auxiliary device is located on the rear side of the machine body, and the seedling stand is configured to be divided into a plurality of divided seedling stand parts. The divided seedling planting device is divided into a plurality of divided seedling planting device parts, each of which is provided with the divided seedling placement base part, and a splitting auxiliary device part in which the auxiliary device is divided to form a plurality of divided work device parts. , Each of the divided work device unit, while setting the adjacent work posture so that the seedling placement surface of the split seedling placement unit section is continuous in the machine lateral direction, the each divided work device unit,
It is configured to switch to a non-working posture in which the seedling placing surface of each of the divided seedling placing parts is arranged so as to face each other in a state along the machine front-rear direction, and in each of the working device portions,
With respect to the division seedling planting device unit the division auxiliary device unit,
It is configured so that the position can be changed between the working position and the non-working position retracted from the working position, and the function and effect thereof are as follows.

[0005]

In other words, since the work device can be divided into two divided work device parts in a state of being attached to the traveling machine body, and the divided work device parts can be switched to the non-working posture. The work width can be switched between the working posture and the non-working posture while the occupation width in the left-right direction of the traveling body is reduced. Here, not only the seedling planting device but also the entire working device including the auxiliary device can be divided to switch to the non-working posture described above, so it is necessary to separately attach the auxiliary device and the seedling planting device to the traveling machine body. Instead, the working device may be attached as a unit. Further, referring to the auxiliary device, in this auxiliary device, each divided auxiliary device unit belongs to each working device unit, and each divided auxiliary device unit can be independently moved relative to each divided seedling planting device unit. Therefore, the rear of the split seedling planting device can be opened when the work for the split seedling planting device is performed, for example, when the remaining seedlings on the seedling surface are removed after the work is completed, the operator is cramped. There is no need to work in a posture or in a narrow space. Moreover, since it is possible to move with respect to the divided seedling planting device unit for each divided auxiliary device unit, the worker does not need to move the auxiliary device integrally.

[0006]

As a result, the work load required for switching the postures of the divided work device sections can be reduced, and by setting each divided work device section in the non-working posture, it can be mounted on the road and carried on a transport vehicle well. Can be done. Moreover,
It is possible to form a mounting structure for mounting the working device on the traveling machine body as a unit, and to simplify the mounting structure. Moreover, since it is possible to move the divided auxiliary device units, it is possible to reduce the work burden imposed on the worker for the movement as compared with the case where the auxiliary device is moved integrally.
