Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter, and more particularly to improvement of a seedling planting device connected to a traveling machine body.

[0002]

2. Description of the Related Art A seedling planting device connected to a rice transplanter is a seedling platform on which mat-shaped seedlings are placed, and a planting arm for cutting one seedling from the bottom end of the mat-shaped seedlings and planting it in a field. , A plurality of ground leveling floats, and a transmission system for driving them, etc., and conventionally, in a seedling planting device for multi-row planting such as 8-row planting, the dimension in the lateral width direction is large, and Since it is a form that projects greatly in the direction, when traveling on the road etc. during non-working, the seedling planting device is temporarily separated from the machine body, and the posture of this seedling planting device is rotated by 90 degrees ( The lateral direction is set to the front-back direction of the machine body, and the lateral end of this seedling planting apparatus is connected to the machine body and pulled to reduce the amount of lateral extension of the seedling planting machine from the machine body.

[0003]

However, as described above, the work of changing the posture of the seedling planting device and connecting it to the machine body is not only time-consuming, but also requires time and labor, and there is room for improvement. . For the purpose of eliminating this inconvenience, the seedling planting device is divided into planting strip units, and by connecting the divided parts via hinges etc. so that the posture can be changed freely, a storage posture that reduces the amount of overhang in the lateral direction of the aircraft It is also conceivable that the configuration can be switched freely.

Considering a case in which the seedling planting device is configured to be freely split and the amount of protrusion from the machine body of the seedling planting device is reduced by changing the posture of the split product, a multi-row planting plant such as an eight-row planting plant is considered. Since the seedling planting device for plants is large in size and relatively heavy in weight, it requires labor to store it manually, and it is desired to reduce the labor.

In addition, when the seedling planting device configured to be freely divided is switched to the retracted posture, the pivot shaft may be set at an appropriate position, and the swinging motion may be switched between the working posture and the retracted posture. Conceivable. However, since the swinging operation is a combination of a rotating operation and an operation along an arcuate locus, the operation form is limited, and there is room for improvement in terms of increasing the operation range.

An object of the present invention is to provide a rice transplanter that can easily perform switching to reduce the amount of overhanging of the seedling planting device in the lateral direction of the airframe when not in operation, and yet obtain a desired operation mode for the seedling planting device during this switching. There is a point in configuring.

[0007]

A feature of the first invention is that a seedling planting device for planting a plurality of rows, which is connected to a traveling body, is divided into planting strip units, and the body of the seedling planting device after the division. The storage posture that reduces the amount of lateral overhang and the work posture that does not divide are configured to be freely switchable, and the operation to rotate the divided objects when dividing the seedling planting device to reduce the amount of lateral overhang. Is provided with an actuator for setting the storage posture by performing the following. The operation and effect are as follows.

Further, the second aspect of the present invention is that the seedling planting device for planting a plurality of rows connected to the traveling machine body is divided into planting strip units, and the divided seedling planting device is moved by movement according to the guide member. It is configured so as to be freely switchable between a storage posture in which the amount of overhang in the lateral direction of the machine body is reduced and a work posture in which no division is performed. The action and effect are as follows.

[0009]

According to the features of the first aspect of the invention, when the storage device is retracted, the divided pieces of the seedling planting device are turned by driving the actuators to reduce the amount of extension of the divided pieces in the lateral direction of the machine body.

That is, since the multi-row seedling planting device originally has a large lateral dimension, it is necessary to divide it into planting row units and perform a turning operation to reduce the amount of lateral overhang of the machine. Therefore, it is possible to store the image without difficulty, and since the turning operation is performed by the actuator, the labor burden on the operator can be reduced.

According to the feature of the second aspect of the invention, the seedling planting device is divided at the time of storage, and the divided object is moved to the storage posture by moving according to the guide member, so that the lateral extension of the machine body is reduced and the backward direction is reduced. It is also possible to switch to the work posture by operating.

In other words, since the multi-row seedling planting device originally has a large lateral dimension, it is divided into planting strip units and moved according to the guide member to form, for example, a swing type locus. It is possible to freely set the operation form and not to increase the operation range, as compared with the case of operating along. The second invention does not prevent the second invention from being used in combination with a swing type link or the like.

[0013]

Therefore, when not in operation, it is possible to easily and effortlessly switch the seedling planting device so as to reduce the amount of lateral extension of the device, and at the time of this switching, the rice planting device obtains a desired operation mode. The machine was reasonably constructed.
