Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter in which a planting device is connected to the rear of a traveling machine body so as to be swingable from side to side around a vertical axis.

In this type of rice transplanter, the orientation of the planting device can be automatically changed to the steering direction of the traveling device or a direction close to this by swinging the planting device left and right with respect to the traveling device. Although it is possible to successfully plant along curved ridges while suppressing mud pushing laterally by the planting device as much as possible during planting work in the field, etc., when planting straight ahead, the traveling machine body If the plant is temporarily moved laterally in the left-right direction due to unevenness, etc., the planting device tends to follow the same and move laterally, which has the disadvantage of causing meandering of the planted shoots.

The present invention has an object to improve the above-mentioned drawbacks, and a characteristic configuration of the present invention made to achieve the above object is that the planting device is provided with a resistor against lateral movement of the planting device. It is at the point.

The functions and effects of the above characteristic configuration are as follows.

In other words, by providing the above-mentioned resistor in the planting device to make the lateral movement of the planting device a little slower, the planting device can be moved when the steering time of the traveling machine is long, such as when planting along a curved ridge. Although the aircraft was turned to the steering direction and planted while driving with less mud pushing, the aircraft temporarily moved laterally to the left or right due to unevenness of the plowing platform during the straight planting process. In some cases, it has been possible to suppress the following lateral movement of the planting device as much as possible, and it has become possible to perform good planting with no or little meandering.

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

The riding rice transplanter consists of an integrated top link 3 and a pair of left and right links that are movable vertically and horizontally using its front end as a fulcrum at the rear of a traveling body A that is equipped with front and rear wheels 1, 2 and a control section 10. The lower links 4, 4 are provided, and a mounting frame 5 in a vertical direction is provided over the rear of these links 3 and 4, 4.
The mounting frame 5 is equipped with a planting device B equipped with a seedling stand 6 and a ground float.
A transmission case 8 is installed, and a hydraulic cylinder 9 for driving and lowering the planting device B is installed between the traveling body A and the top link 3 in a state that allows the top link 3 to swing from side to side. death,
In addition, the planting device B is configured so that it can be driven up and down with respect to the traveling body A, and is also configured to be swingable in the left and right directions using the front connecting portion of the top link 3 and the lower links 4, 4 as a fulcrum. are doing.

The stay 10 extending forward from the transmission case 8 of the planting device B has a plurality of resistors that have sharp surfaces along the direction of movement of the aircraft and can provide resistance to lateral movement of the planting device B. The body 11 is connected to the tiller surface with an appropriate distance therebetween.

By providing such a resistor 11 to slightly slow down the lateral movement of the planting device B, when the traveling body A is temporarily moved laterally in the left and right direction due to unevenness of the plowing surface, etc., the planting device B can follow the movement of the planting device B. This makes it possible to suppress lateral movement as much as possible, allowing for successful planting with less meandering.

FIG. 4 and FIG. 5 show another embodiment, in which the resistor 11 is connected to a plurality of resistors (11) that can be grounded on the tiller and that can freely swing up and down around the horizontal axis P at the front end. It is composed of a sled body (even one piece is fine), and
This sled body 11 and the mounting frame 5 of the planting device B
A hydraulic cylinder 12 is interposed between the plant and the plant, and by vertically swinging the sled body 11 with the hydraulic cylinder 12, the planting depth by the planting device B can also be adjusted.

FIG. 6 shows another embodiment, in which the resistor 11 is connected to a plurality of resistors that can be grounded on the tiller and that can swing up and down integrally around the horizontal axis P at the front end of the resistor 11. It is composed of sled bodies and is provided with a coiled spring 13 that biases the sled bodies 11 toward the ground side.
