Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a seedling transplanter equipped with a seedling feeding device on a seedling mounting table.

2. Description of the Related Art Conventionally, a seedling feeder that acts on a bottom surface of a seedling to transfer a seedling is provided on a lower side of a seedling mounting table that is obliquely arranged with one side being front and rear and the other side being lower. At the time of work, there was a seedling feeding device that operates with the lower side of the seedling mounting table as the seedling feeding direction.

[Problems to be Solved by the Invention] When the rice transplanting work is advanced by the rice transplanter, the seedlings placed on the seedling mounting table and sent to the seedling dividing port are often pulled up to the upper side of the seedling mounting table. is there. For example, in the case of planting at the ridge, when planting with fewer rows than the number of rows of the planting device mounted on the rice transplanter, that is, pull up the seedlings remaining on the seedling mounting table when the planting operation is completed. It is necessary to remove the seedlings, and if there are any clogged seedlings or foreign matter near the division opening, remove them by 10-20 to remove them.
It was necessary to raise the seedling by about cm. In addition, when planting fractional rows, sometimes the seedlings that are not to be planted are pulled up from the seedling division and planted for the required number of rows.

Therefore, the conventional seedling feeder cannot feed the seedlings to the upper side of the seedling mounting table, so that the worker pulls up the seedlings by directly grasping the seedlings by hand. However, at this time, the seedlings were torn apart, so that the seedlings were broken apart and could not be lifted well. If the seedlings are torn, the seedlings can no longer be placed on the rice transplanter and used again. In addition, when the fertilizer application device is arranged on each line behind the seedling mounting table, it is difficult to take out the seedlings near the seedling split opening directly from the rear of the seedling mounting device because the fertilizer application device is in the way. It became difficult to raise the seedlings. In particular, it was difficult to reach the seedlings on the side of the central strip from both the left and right sides, which hindered raising the seedlings of the strip.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention operates on the bottom side of the seedling on the lower side of the seedling mounting table 12 which is obliquely arranged with one of the front and rear sides as upper and the other side as lower. A seedling feeder 26 for transferring seedlings and providing upper seedling feeders 33 and 41 above the seedling feeder 26. At least the seedling feeders 26. At the time of work, the lower side of the seedling mounting table 12 operates as the seedling feeding direction, and at least the upper seedling feeders 33, 41
Is a seedling transplanter provided so that the upper side of the seedling mounting table 12 can be operated and operated in the seedling feeding direction when the operation is stopped.

[Operation and Effect of the Invention] At least the seedling feeders 26... Operate in the seedling feeding direction with the lower side of the seedling mounting table 12 at the time of seedling work. Since the upper side of the seedling mounting table 12 is provided so as to be operated in the seedling feeding direction, the seedling feeder 26 acts on the lower side of the seedling mounting table 12 to transfer the seedling to the lower side of the seedling mounting table 12 during the seedling operation. Thus, the seedlings placed on the seedling mounting table 12 can be appropriately sent in the lower direction, so that good seedling planting work can be performed. On the other hand, when taking out the seedlings placed on the seedling mounting table 12 when the operation is stopped, at least the upper seedling feeders 33, 41 must be moved to the seedling mounting table 1.
By operating the upper side of 2 as the seedling feeding direction, the seedlings placed on the seedling mounting table 12 can be properly pulled up to the upper level of the seedling mounting table 12, and the conventional problems can be appropriately solved. it can.
