Description

[Detailed Description of the Invention] The present invention provides a seedling planting device that is removably connected to the rear of the traveling machine and has a width larger than the front and back, and is attached to the rear of the traveling machine with its width direction facing the front and back direction. Regarding rice transplanters configured to be mounted on a trailer that is detachably connected to the rear of the rice transplanter, the rice transplanter is designed to facilitate the work of assembling the seedling planting device mounted on the trailer to the traveling machine. be.

The above rice transplanter has a seedling planting device that is larger than Yokoyama in front and rear widths.
When traveling on the road, the vehicle can be placed on a trailer that is removably connected to the rear of the vehicle with its width facing forward and backward, thereby avoiding damage from contact with other objects. However, there was a problem in that it was difficult to assemble the seedling planting device placed on the trailer to the traveling body.

That is, in order to assemble the seedling planting device to the traveling body, a frame to be connected to the traveling body is provided at the front end of the seedling planting device placed on the trailer, and a frame is provided at the rear end of the traveling body. It connects and fastens the seedling planting device connection frame.

Conventionally, the height above the ground of the frame to be connected and the height above the ground of the connecting frame are set to be the same when the trailer and the traveling body are supported on the ground at the same height. In this case, there are many unevenness on the farm roads in or near the fields, making it difficult to support the trailer and the traveling machine on the ground at the same height. There was a problem in that the assembly work was difficult to perform due to the vertical relative position deviation.

The present invention was made keeping in mind the above actual situation,
In the rice transplanter having an official structure, the seedling planting device is placed on the trailer so that the rear end thereof is centered and the front end thereof is swingable upward, and the trailer and the traveling body are placed at the same height. When the seedling planting device is supported on the ground on the ground, the height above the ground when the frame to be connected to the trailer is mounted on the traveling body provided at the front end of the seedling planting device is set at the rear end of the traveling body. The height of the seedling planting device is set smaller than the height above the ground of the connection frame of the seedling planting device.

That is, the seedling planting device is placed on the trailer so that the front end can swing upward with the rear end centered, and the connected frame provided on the front end of the seedling planting device is moved upward. While making it possible to change the position, and in a state where the trailer and traveling aircraft are supported on the ground at the same height, the ground height of the connected frame when it is mounted on the trailer is set to be higher than the ground height of the connecting frame. Because the setting is small, even if it is not possible to support the trailer and the traveling aircraft on the ground at the same height, by changing the position of the connected frame upward, it is easy to connect the connected frame and the connecting frame. This makes it possible to make the top and bottom heights the same.

As a result, this rice transplanter solves the problem of government registration, makes it easier to assemble the seedling planting device mounted on the trailer to the traveling body, and is more convenient to use overall. I ended up getting this.

Embodiments of the present invention will be described in detail below based on illustrative drawings.

FIG. 4 shows a side view of the seedling planting device 2 placed on a trailer 3 removably connected to the rear of the tractor 1 with its width direction facing the front-rear direction, and FIG. ing.

The seedling planting device 2 includes a seedling platform 4 in an inclined position located at the front of the upper part which can be horizontally reciprocated with a constant stroke, and a vertical circulation operation between the lower end of the seedling platform 4 and the mud. Eight planting nails 5 arranged side by side at appropriate intervals in the horizontal direction.
and five floats 6 arranged side by side at appropriate intervals in the lateral direction.
・ etc., and the seedlings are taken out one by one along the lower row of the bacterial group placed on the seedling stand 4 and planted on the leveled field using the float 6 ・ etc. The system is structured in such a way that it

To explain the connection structure of the seedling planting device 2 to the tractor 1, a pair of left and right connecting frames 7, 7 to the tractor 1 provided at the front end of the seedling planting device 2 are connected to the rear end of the tractor 1. It is removably connected and fixed to a pair of left and right seedling planting device connection frames 8, 8 provided on the sides, and is rotatably supported around the horizontal axis X, and is attached to the rear end of the tractor 1. Pivoted so that it can swing up and down,
In addition, a pair of left and right lift arms 10, 10, which are vertically swung by a hydraulic cylinder 9, and a pair of left and right links 11, 11, which are pivotally supported to the seedling planting device 2 in a vertically swiveling manner, are removably pivoted. Supported.

The seedling planting device 2 is connected to the seedling planting device 2 so as to be able to swing up and down about the horizontal axis center X and to be detachable.

The trailer 3 includes a mounting base 13 equipped with a pair of left and right free wheels 12° 12, a connected frame 14 extending forward and upward from the front end of the mounting base 13, and a frame 14 that is removably attached to the front end of the connecting frame 14, a connecting frame 15 that is pivotably connected to be swingable around an axis Y and that is detachably connected to the tractor 1;
, and a stand 16 that supports the mounting base 13 on the ground in cooperation with the idle wheels 12, 12 when the connected frame 14 is separated from the connecting frame 15.

Note that the connection frame 15 has a corresponding connection frame 14.
A pair of left and right poles that can contact and restrict the swinging angle of the poles, and change the swinging angle by adjusting the rotation.17.1
