Description

TECHNICAL FIELD The present invention relates to an apparatus for transplanting seedlings raised in a paper cylinder, and more specifically, it may be selected by a seedling selection apparatus and sent at different seedling intervals. Even so, it provides a device that can regulate the normal planting interval.

(Prior Art) Conventionally, when cultivating sugar beets, onions, tobacco, paddy rice, etc., it is widely practiced to transplant soil-grown seedlings raised in a paper cylinder with a transplanter. 57-202212
No. 58/117319 and the like. Originally, when seedlings were raised in a paper tube, some of the seedlings had good growth that was normal,
Since there are defective seedlings that do not germinate or that do not germinate even if they germinate and are not suitable for transplantation, the defective seedlings should be manually selected and transplanted by the transplanter described in JP-A-57-202212. As described in Sho 58-117319, the transplanter is equipped with a sorter for selecting seedlings with two belts that support the leaves and roots, and transplants while automatically sorting.

(Problems to be solved) However, according to the transplanter described in Japanese Patent Application No. 58-117319, the paper seedlings are first separated in parallel at regular intervals,
Since they are re-paralleled after sorting, the paralleling intervals are likely to be uneven, and if they are conveyed by a transfer belt at regular intervals and planted, the planting intervals are likely to be uneven. In addition, the sorting device and the planted disc are configured to be performed by the same grounding wheel, but when the sorting device is installed, the device becomes complicated and the grounding wheel is overloaded and slips occur in some fields, resulting in a planting interval. There was a problem of making them unequal.

(Means for Solving the Problem) The present invention has conducted research to obtain a transplanter that can be planted at regular intervals even if a sorting device is attached, and holds a seedling from the sorting device and vertically clamps the belt for vertical transfer. It is composed of two stages, a seedling detection sensor is provided under the upper belt, rotation can be stopped by detecting the seedling of the sensor, and a planting circle is attached to the shaft that is interlocked with the planting disc driven by the grounding wheel. A plate rotation counter was attached, and when the planted disc rotated a predetermined rotation angle, the stopped upper belt was rotated to pass the seedlings to the lower belt, and further the seedlings were passed to the planted disc to be planted. However, if the drive source for the planted disc and the drive source for the sorter are separate, a better regulation effect can be achieved.

(Operation) Paper seedlings are separated into rows by manpower or a seedling row separator, and placed on the seedling supply conveyor 72. The seedling rows are separated one by one by the seedling separating roller 78 and fall on the root support belt 65 and the leaf support belt 57, and the defective seedlings are sorted and conveyed. Next, by the first belt 36, 36 ', which rotates rapidly, the upper part of the belt is conveyed downward while being held in a state of being protruded, and the protruding seedlings reaching the lower end of the conveyance are detected by the seedling detection sensors S, S'. Then, the temporary transfer is stopped and put on standby.

On the other hand, the rotation axis 15 of the planted disc 14 is made to count the rotation angle by the planted disc rotation counter 81, and when the counted value reaches a predetermined value, a signal is sent to the microcomputer 80 and the stopped upper stage. The belt is rotated and the seedlings are passed to the lower belts 26 and 26 'and further the seedlings P are passed to the planting disc 14 to be planted.
