Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a straw sorter or the like for splitting a densely grown mother strain into small strains suitable for transplantation into a field.

[0002]

2. Description of the Related Art Conventionally, as a strawberry plant stock sorting machine, as shown in Japanese Patent Application No. 4-120933 filed earlier, the facing distance becomes smaller as the pair of endless rotary bands with needles goes downward. A pair of reciprocating claws is arranged at the lower end of the conveying device arranged in a downward constriction shape, and the mother stock introduced by the spreading operation of the endless rotation band needle in the lower ring and the reciprocating claw There has been proposed a stock splitting machine configured with a splitting device for splitting into stocks.

[0003]

With the stock splitting machine according to the above-mentioned technique, the process of splitting the mother stock into small stocks is mechanized. However, when the divided small caplets are supplied to a planting machine such as a strawberry transplanter, they are actually collected in a storage box equipped with a large number of small caplets. Had to be done manually. An object of the present invention is to provide a stock sorting machine that is mechanized from the division of mother stocks to the packaging of small stocks, and particularly a stock sorting machine that can be packaged with high efficiency.

[0004]

Means for Solving the Problems To achieve the above object, the present invention is a division in which the root portion of a mother plant conveyed by a carrier device is forcibly disentangled and dispersed in order to divide it 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 this stock splitting unit into a storage box, and an extrusion device, and an extruding tool arranged in the storage box. , A reciprocating mechanism for reciprocating the pushing tool in the small-capsule packing direction and the opposite direction, and at the end of the pushing tool in the small-caps packing direction, the pushing tool is rotated about the vertical axis. The push-out device is provided with a terminal swinging mechanism for swinging and swinging.

[0005]

[Function] In order to provide a boxing unit for small caplets as a device part of the stock sorting machine, the discharged small caps should be packed in the storage box. Since it is not sufficiently packed only by transferring, small stocks can be satisfactorily sequentially stored in the storage box by providing an extruding device composed of a reciprocating movement mechanism that reciprocally moves the pushing tool in the small stock packing direction and the opposite direction. It becomes possible to pack and transfer. It is convenient in terms of filling rate if the small caps to be discharged can be packed evenly in the width of the storage box.
In reality, the closer to the left and right ends, the less likely it is to get stuck. Therefore, in the present application, the terminal swinging mechanism swings the pusher around the vertical axis at the end of the movement in the small-capsule packing direction, so that the swinging swings the pusher to the left and right ends in the storage box. Sufficient stuffing pressure can be applied to a certain small cap, and the small cap can be stuffed and transferred across the left and right sides of the storage box.

[0006] By the way, as a structure for swinging and swinging the head, a means for gradually swinging the extruding tool as it moves in the small-capsule packing direction can be considered. Since it is much larger, it is expected that the gradual swinging means does not significantly change the pressing force acting on the left and right ends of the box as compared with the case of simply pushing out. On the other hand, in the extruding means of the present application, the pressing force due to the swing movement further acts on the left and right ends of the box predominantly at the time when the packing transfer by the extruding tool is completed or almost completed. Therefore, the filling rate at the left and right ends of the box can be further increased.

[0007]

As a result, it is possible to provide a rational stock splitting machine that can mechanize a series of operations from stock splitting of mother stocks to boxing of small stocks while maintaining excellent efficiency of filling small stocks into the storage box in the packing section. We were able to.
