Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a vegetable transplanter.

[0002]

2. Description of the Related Art As a conventional vegetable transplanter, a seedling is taken out from a seedling tray by a seedling catcher, and the taken-out seedling is supplied to an opening device, and the opening device is displaced and moved toward a ridge. 2. Description of the Related Art There is known a configuration in which a seedling is transplanted to a ridge while traveling in a field.

[0003]

However, in the above-mentioned conventional vegetable transplanter, which has only one opener, when the vegetable transplanter is run once along the ridges, it has a problem. Only the seedlings can be transplanted. Therefore, in order to improve the cultivation efficiency, to transplant the seedlings in two rows on the ridge or in a staggered manner, run the vegetable transplanter several times along the ridge. And required a lot of effort and time.

[0004]

Therefore, according to the present invention, a planting mechanism for planting seedlings in ridges and a seedling supply mechanism for supplying seedlings to the planting mechanism are provided on a traveling machine, respectively. In a vegetable transplanter that transplants seedlings to ridges while traveling, a pair of left and right planting mechanisms are arranged on the traveling machine body, and the seedling supply mechanism supplies alternately the seedlings to the left and right planting mechanisms. I decided that.

In the seedling supply mechanism, a seedling supply passage is formed, and the end of the seedling supply passage is alternately connected to the left and right planting mechanisms, so that the seedlings are alternately supplied to the left and right planting mechanisms. It was decided to be constituted.

In the seedling supply mechanism, a seedling supply passage having a passage switching valve formed at a branch portion and communicating with both the left and right planting mechanisms and having a passage switching valve at a branch portion is formed. By operation, it was configured to supply the seedlings alternately to the left and right planting mechanisms.

BEST MODE FOR CARRYING OUT THE INVENTION A vegetable transplanter according to the present invention is provided with a planting mechanism for planting seedlings in ridges and a seedling supply mechanism for supplying seedlings to the planting mechanism on a traveling machine, respectively. The seedlings are transplanted to the ridges while traveling in the field.

[0008] The planting mechanism is disposed on the traveling machine body at an interval in the lateral width direction.

In the seedling supply mechanism, a seedling supply passage is formed, and the end of the seedling supply passage is alternately connected to the left and right planting mechanisms, so that the seedlings are alternately supplied to the left and right planting mechanisms. doing.

[0010] A seedling supply passage having a passage switching valve formed at the branch portion and communicating with both the right and left planting mechanisms and forming a seedling supply passage is formed on the way to the seedling supply mechanism. It is also possible to configure so that seedlings are alternately supplied to the left and right planting mechanisms.

[0011] Two runs of seedlings can be simultaneously planted on the ridges by the planting operation of the left and right planting mechanisms only by running once on the ridges, and the seedlings can be planted on the ridges by the left and right planting mechanisms. By operating to plant alternately,
The seedlings can be planted on the ridges in a staggered arrangement at regular intervals, thereby greatly reducing the time and labor required for the transplanting operation.
