DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stocking machine for rush and the like for dividing a mother plant grown densely into small plants suitable for transplanting to a field.

[0002]

2. Description of the Related Art Conventionally, as a rush plant sorter, as shown in Japanese Patent Application No. 4-120933 filed earlier, the opposing distance becomes shorter as the pair of endless rotary bands with needles goes downward. A pair of reciprocating claws are arranged at the lower end of the conveyer device arranged in a constricted manner, and the mother stock inserted by the spreading operation of the endless rotary band needle in the lower ring and the reciprocating claws is a small stock. There has been proposed a stock sorter in which a dividing device for dividing into stocks is configured.

[0003]

In the stock splitting machine according to the above-mentioned proposed technology, the process up to splitting a parent stock into small stocks is mechanized. However, when the split small plants are supplied to a planting machine such as a rush transplanter, they are actually collected in a storage box with a large number of small plants. Had to be done manually. An object of the present invention is to provide a stock sorting machine that is mechanized from splitting of a parent stock to boxing of small stocks, in particular, a stock sorting machine that can pack boxes with high efficiency.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a dividing method which acts on the roots of a mother plant conveyed by a conveyor and forcibly disperses and disperses the roots to divide them into small plants. A stock splitting unit equipped with a device, and a box packing unit equipped with an extruding device for sequentially packing and transferring small stocks discharged from the stock splitting unit into a storage box, and an extruding device, an extruding tool arranged in the storage box. A reciprocating mechanism for reciprocating the extruding tool in the small-packing direction and in a direction opposite to the small-packing direction, and at the end of movement of the extruding tool in the small-packing direction, move the extruding tool around the vertical axis. The extruder is provided with an end swing mechanism for swinging the head.

[0005]

In order to provide a boxing section for small stocks as one device part of a stock sorting machine, it is sufficient to pack the discharged small stocks in a storage box. Since the transfer alone does not sufficiently pack the small stocks into the storage box, the extruder is provided with an extruding device comprising a reciprocating mechanism for reciprocating the extruder in the small-packing direction and the opposite direction. It becomes possible to pack and transfer. It is convenient in terms of the filling rate if the discharged small stocks can be packed all over the width of the storage box,
In reality, there is a tendency for the clogging to become less favorable toward the left and right ends. Therefore, in the present application, the extruding tool is configured to swing around the vertical axis at the moving end in the small-packing direction by the end swing mechanism. Sufficient stuffing pressure can be applied to a certain small stock, and the small stock can be packed and transferred across the left and right sides of the storage box.

As a structure for swinging the head, a means for gradually swinging the pusher along with the movement of the pusher in the small-packing direction can be considered. Since it is much larger, it is expected that the pressing force acting on the left and right ends of the box will not be much different from the case of simply pushing out with this gradual swinging means. On the other hand, in the pushing means of the present invention, at the time when the packing by the pushing tool is completed or almost finished, the pressing force due to the swing movement mainly acts on the left and right ends of the box. Thus, the filling rate at the left and right ends of the box can be further increased.

[0007]

As a result, there is provided a rational stocking machine which can mechanize a series of operations from stock splitting of a parent stock to boxing of small stocks while maintaining a state of excellent small stock filling efficiency in a storage box in a box packing section. We were able to.
